257589 | Matt Ridley in [Rational Optimist](https://en.wikipedia.org/wiki/The_Rational_Optimist:_How_Prosperity_Evolves) says that countries are prosperous when divided due to competition among government. Countries are backward when united.
According to this theory, China advanced after dividing. Sung is after chaos that followed the Tang dinasty.
During the Ming dynasty, the Chinese send one big freakin fleet. After some reasonable success of the fleet, the one government unilaterally stopped the expedition and prohibit all ships production to prevent private enterprise from sailing ahead.
These stupid decisions can't be made collectively by Europeans. Europeans consist of many countries and no one idiotic emperor can prevent the whole civilization from exploring.
This explains why Europe became far more advanced than the Chinese.
Yet, Europeans do not seem to prosper when the Roman Empire fell and they got divided into many smaller tribes fighting each other.
So what's the catch?
Does Mr. Ridley's theory stand up when examined across history? Are there counterexamples or alternative compelling theories? | Ridley's argument as presented above is very simplistic. Fragmentation may sometimes lead to prosperity, but only if a number of other conditions are fulfilled. To my mind, these other conditions are more important and more interesting than the number of countries in the world, which seems incidental and arbitrary. Does Ridley think more fragmentation is always better, or are these diminishing returns when you reach [the levels of the Holy Roman Empire](https://en.wikipedia.org/wiki/List_of_states_in_the_Holy_Roman_Empire)? Is there something magical about our 195-some countries today, or would we for some reason be more prosperous if the U.S. split up into 50 countries?
What are some of these preconditions for prosperity among political fragmentation? For example, fragmentation of government does not lead to wealth if [every minor baron demands a toll to use his road or float barrels down his river](https://en.wikipedia.org/wiki/Road_toll_(historic)). This is grossly inefficient. The Roman Empire (which mind you, also had the revenue to invest in roads and other infrastructure) was more conducive to growth.
Political fragmentation can also lead to a lack of standardized currency, volatile exchange rates, and jealous attempts to protect domestic industry, all of which can slow growth. The United States' economy [puttered](https://en.wikipedia.org/wiki/America's_Critical_Period#Debt_and_Taxes) under the Articles of Confederation, but started to prosper after the new Constitution sought further political integration of the states--which led to further economic integration. Note that it was the merchants of New England and the pro-growth Hamiltonians who wanted closer political integration in order to achieve economic integration.
Note also that governance can exist at many levels. The modern state system has been accompanied by a proliferation of trade-related international agreements. These often seek to harmonize domestic laws, establish international standards, standardize payment methods, protect property rights, tear down tariffs and customs. International political economy faces enormous pressures for coordinated governance at the highest levels--and that level of coordination appears all the higher when we consider the role of behemoth transnational corporations, which generate a "private" layer of world governance. It's unlikely that the modern economy could sustain such high levels of economic integration without these many, many public and private coordinating mechanisms.
**TLDR:** A fragmented world is conducive to growth in some ways (innovation; distribution of wealth) but deleterious in other ways (incompatible standards; higher barriers of trade). However, the fact that governance exists at subnational levels means that even very large political entities can enjoy great periods of economic growth and innovation; the fact that governance also exists at supranational levels means that even a world as fragmented as today's can enjoy the benefits of political integration. The number of countries is only loosely related to the quality of governance, and so it's better to write directly about the policies and institutions conducive to growth, trade, and innovation. |

Maybe because you a missing the worksheetname before `Rows(CStr(LSearchRow) & ":" & CStr(LSearchRow)).Select`?
After the code executes this line
`ThisWorkbook.Worksheets.Add After:=Worksheets(Worksheets.Count)`
The current sheet is the new sheet and hence it will refer to the newly created sheet. And later the `wks.Select` returns the control back to your main sheet.
So change that to
```
wks.Rows(CStr(LSearchRow) & ":" & CStr(LSearchRow)).Select
```
Also your entire sub can be re-written as (**UNTESTED**)
```
Option Explicit
Sub Sample()
Dim LSearchRow As Long, LCopyToRow As Long
Dim wks As Worksheet, wksCopyTo As Worksheet
On Error GoTo Err_Execute

257815 | I'm trying to stop certain fields being changed by the user. However I don't know what columns those fields will be in, only what value they will initially contain.
My current approach is this:
```
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
Dim columnHeaderRange As Range
Set shtData = Worksheets("Data")
Set columnHeaderRange = Union(shtData.Columns(ColumnNumber(5, "example1")), _
shtData.Columns(ColumnNumber(5, "example2")), _
shtData.Columns(ColumnNumber(5, "example3")))
Set columnHeaderRange = Application.Intersect(Target, columnHeaderRange)
ElseIf Not (columnHeaderRange Is Nothing) Then
With Application
.EnableEvents = False
.Undo
MsgBox "Change is not possible.", 16
.EnableEvents = True
End With
Else
Exit Sub
End If
```
My ColumnNumber function in the above code takes the row and field value as parameters and returns the column number. Since I'm using fixed field values though, this fails if a field has been changed so my union call fails.
Is there a way to have this code run upon a user attempting to change the value of a cell but before the actual value of the cell is changed? Alternatively can anyone suggest a better approach? | Further to my comments
**EXAMPLE 1**
Create a sheet called `List`, which will store your values. The best part about this method is that you do not have to amend the code every time you want to add/delete items from your list.
See Screenshot
And let's say this is your main sheet
Paste this code in the Sheet Code Area

258012 | seems like a very, common & frustrating topic... but my wifi is at a super slow crawl. I am getting speeds slower than dial-up modems, which gets maddening when you are trying develop a website.
**TEMPORARY SOLUTION**
After trying -EVERY- solution below, nothing worked. So I used Timeshift and rolled back my machine to Oct. 22nd, then I did NOT do any updates or upgrades.. and now wifi seems to be working pretty well. So I plan to ignore updates & upgrades for the next month and see if the problem gets corrected elsewhere. It was definitely a recent update that caused this problem.
This is my hardware:
```
$sudo lshw -class network -short && nmcli device status

[Ubuntu 20.04 Network Performance Extremely Slow](https://askubuntu.com/questions/1230525/ubuntu-20-04-network-performance-extremely-slow)
and nothing has worked.
Does anybody have any new tricks, that I can try? even 1MB download would be a blessing from the heavens.

Also, it is always slow at boot time. | So It just depends on you what you want, I can only suggest because your system specs are OK, You can have any type of ubuntu flavour you want, Let me give you a brief Idea
You can find alternatives of ubuntu I.e ubuntu flavours [here](https://ubuntu.com/download/flavours)
---
Lubuntu
=======
A good Linux distro, If your PC isn't much good in specs then Lubuntu can help you to get maximum performance even from an ultra potato PC, It also offers an OK GUI, It also comes with a handful of apps and stuff, So I guess it would be good for you PC specs,
[Official page of Lubuntu](https://lubuntu.me)
[Wikipedia Page of Lubuntu](https://en.m.wikipedia.org/wiki/Lubuntu)
---
Xubuntu
=======
Good for performance with very minimal memory usage, This is what is good and recommend for your PC.
It would be good in this case as you are not on a bad PC, It is just normal. Lubuntu is designed for a very minimal thing. But Xubuntu can help you as it is for the average PC and works well even with very good PCs
<https://xubuntu.org/about/>
---
Kubuntu
=======
Good for a beautiful GUI, It may cut off some performance but is beautiful. But as your specs it will not give much performance, So it's not for heavy use as per your specs but it is good if you are a GUI lover
More info can be found at
<https://kubuntu.org/about-us/>
---
Ubuntu Vanilla
==============
Good but I don't recommend it for your specs, Don't install it.
---
I cannot tell you everything all about distros but you need to check out more about them yourself
=================================================================================================
---
CONCLUSION
==========
It depends on your admiring, every distribution is good, but I would personally recommend Xubuntu for you.
---
**There are many other distros too, check out Gentoo, mint, kali or Garuda, All these are just the best in their forms**
---
"Every Distribution has its abilities"
======================================

Your specs are good enough to use any of them, So go ahead and pick one today. |
258043 | Right now I'm using an N-Channel MOSFET. I am inputting a 2V pk-pk square wave into the gate, the drain is connected to a bare wire (that is connected to nothing) and the source is connected to ground. For some reason there's a voltage reading in the drain of my MOSFET. Is this normal? | If you see just the "edges" (positive/negative peaks at the times when there are rising/falling edges at the input signal) it can be explained by the capacitance between gate and drain. |
258951 | after a lot of help yesterday, I came up against a known error in asp.net4 beta - I upgraded to VS2012 RC Express (4.5), and now I'm getting an internal server error, and I can't see why. I'm creating a web API:
**Model**
```
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
using System.Data.Entity.ModelConfiguration.Conventions;
using System.Data.Entity;
using System.ComponentModel.DataAnnotations.Schema;
namespace MvcApplication6.Models
{
public class tblCustomerBooking
{
[Key()]
public int customer_id { get; set; }
public string customer_name { get; set; }
public string customer_email { get; set; }
public virtual ICollection<tblRental> tblRentals { get; set; }
}
public class tblRental
{
[Key()]
public int rental_id { get; set; }
public int room_id { get; set; }
public DateTime check_in { get; set; }
public DateTime check_out { get; set; }
public decimal room_cost { get; set; }
public int customer_id { get; set; }
[ForeignKey("customer_id")]
public virtual tblCustomerBooking tblCustomerBooking { get; set; }
}
}
```
I then used the Add Controller wizard, selected "Template: API controller with read/write actoins, using Entity Framework", chose tblCustomerBooking as my Model Class, and clicked , which is:
```
using System.Data.Entity;
namespace MvcApplication6.Models
{
public class BookingsContext : DbContext
{
public BookingsContext() : base("name=BookingsContext")
{
}
public DbSet<tblCustomerBooking> tblCustomerBookings { get; set; }
}
}
```
My Controller (BookingsController.cs) automatically generated by Visual Studio 2012 Express is:
```
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity.Infrastructure;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web;
using System.Web.Http;
using MvcApplication6.Models;
namespace MvcApplication6.Controllers
{
public class BookingsController : ApiController
{
private BookingsContext db = new BookingsContext();
// GET api/Bookings
public IEnumerable<tblCustomerBooking> GettblCustomerBookings()
{
return db.tblCustomerBookings.AsEnumerable();
}
}
}
```
I added a breakpoint at "return db....." above, and checked the Watch part in VS - it clearly shows the object, with the customer, and the associated rentals:
However if I allow the script to continue, I just get an http500 error (as shown in Fiddler below):
Is there any more code I can add into the controller to allow me to see why it is erroring? Or can anyone see what may be wrong? VS appears to retrieve it ok, as shown in the first screenshot, but doesn't seem to be able to send it out.
Thanks for any help or pointers,
Mark
**Update**
Hi - am I simply asking too much of the API? Is it not possible (out of the box) for it to simply return objects with one to many relationships? Can it only really produce a single object list?
Thanks, Mark | You might want to add a global error handler to your project. It can trap and log any odd errors that are happening in background threads.

``` | The problem is that you are expecting too much from `zip`. `zip` is a Python function that generates tuples from iterables. Python tuples are not numpy data structures and therefore cannot respond to an ndim request. If you want to acccess the data points associated with `x`, `y`, and `z` as ndarrays then you want to do something like the example below:
```
from io import StringIO
import numpy as np
txt = """10,10,30
10,20,10
10,30,5
10,40,30

sample_data = np.genfromtxt(s, delimiter=",", names=["x", "y","z"])
sample_data["z"].ndim

259811 | What do I need to do to change the RPCNFSDCOUNT setting without a full service restart?
I need to reload the NFS configuration without restarting the service. The RPCNFSDCOUNT thread count is too low for the workload but I cannot get the management to agree on a schedule for a change window.
A normal service can frequently do this with a SIGHUP. I did attempt this with a `kill -HUP $(pidof rpc.mountd)`, but that was unsuccessful in getting the new RPCNFSDCOUNT setting applied from /etc/sysconfig/nfs on this old Fedora 8 box.
The man pages for the other NFS daemons incline me to think that HUP'ing those processes won't be of any benefit, and I'm rather reluctant to HUP the kthreadd process that is the parent process of the nfsd threads themselves. | And after an obvious mental lapse, I remembered the /proc filesystem. /proc/fs/nfsd, specifically, controls the runtime settings of the nfsd service.
In my case, this meant `echo '32' > /proc/fs/nfsd/threads` sets the number of threads to 32. |
259907 | I'm learning some more PHP and after PHP itself to work, I can't seem to get it to validate any form field correctly. My goal is to check if the firstname field is empty, and if it is, it will give a message in a red color. The message in the red works, but only because the echo script is being called by the form submission, not because it has detected any empty field, because when I made an else statement to say "wassup" if its not empty, I got the same message for when the field is empty. Also, is there a way to check off multiple input fields at once like you could with JavaScript? For example if input1 == '' || input2 == '' and so on. Here is my HTML:

Looks, like this is some adb or Genymotion bug.
To solve this, you must manually connect adb to running Genymotion Device
In first, you need to know Androids internal IP. You can find it in window title of Genymotion device.
Next:
1. cd to your Android SDK dir
2. cd to platform-tools
3. ./adb connect 192.168.57.102:5555
where 192.168.57.102 is my IP address of Genymotion Virtual Device. You must put here your own |

263572 | I am trying build a dictionary of Expressions that have different input parameter types. I am trying to store the type of the parameter because later down the road I plan to use Reflection to discover a method on the type. Here is the code that creates the dictionary and a generic Add function I created to add entries to it:
```
public class LoadEntityQuery : IQuery<LoadEntityQueryResult>
{
public IDictionary<Type, Expression<Func<Type, bool>>> Entities { get; set; }
public LoadEntityQuery()
{
Entities = new Dictionary<Type, Expression<Func<Type, bool>>>();
}
public void Add<T>(Expression<Func<T, bool>> where = null) where T : Entity
{
Expression<Func<Type, bool>> _lambda = null;
if (where != null)
{
ParameterExpression param = Expression.Parameter(typeof(T), where.Parameters[0].Name);
var body = Expression.Invoke(where, param);
_lambda = Expression.Lambda<Func<Type, bool>>(body, param);
}
Entities.Add(typeof(T), _lambda);
}
}
```
The body of the new method is created properly. The issue is when I try to create the new Lambda expression with the type from the expression being passed in, I receive this error:
ParameterExpression of type 'TestNamespace.TestClass' cannot be used for delegate parameter of type 'System.Type'
Does anybody have an idea as to what I can do in this situation? Like I said before, at some point later I am going to loop through this dictionary to do some reflective programming on each entry. If there is a better way to do this I am all ears.
As an example of what I am trying to do, I store the expressions for Where clauses for POCO objects that need to be initialized:
```
LoadEntityQuery _query = new LoadEntityQuery();
_query.Add<PayrollLocation>();
_query.Add<PayrollGroupBU>();
_query.Add<PersonnelPosition>(t => t.DataSet == MasterDataSet);
_query.Add<EmployeeStatus>();
_query.Add<PayrollGrade>();
```
This list of Entities will be different for each app. The idea is to collect all the entities and Where clause for each and discover a certain method using reflection on each one. (e.g. PayrollLocation has a GetPayrollLocationsQuery() method, PayrollGroupBU has a GetPayrollGroupBUQuery() method...). The Add method is generic in order for me to make use of the lambda expression in the calling code.
Thanks,
Jason | Looking closely at your code, the expression you generate has some problems. See my explanation at the top of [this answer](https://stackoverflow.com/questions/5744764/linq-to-sql-throwing-a-stackoverflowexception/5751931#5751931) to explain one of them, it's the same issue here. You're creating a new lambda where the parameter instance you create here is not used in the body.
The bigger problem is that your expressions are just wrong for what you appear to be trying to do. As far as I can tell, you are just trying to create a mapping from entity types to functions that take an entity of that type and returns a bool. `Type -> Expression<Func<TEntity, bool>>`. The expression you build just does not work.
You should make the dictionary store non-generic lambdas that way you can store these functions easily without performing conversions or rebuilding the expressions. You will not be able to store them as generic lambdas here. Then cast to the generic lambda when you access them. I'd put this in a separate class to manage the casting and refactor your code to this:
```
// add all necessary error checking where needed and methods
public class EntityPredicateDictionary
{
private Dictionary<Type, LambdaExpression> dict = new Dictionary<Type, LambdaExpression>();
public Expression<Func<TEntity, bool>> Predicate<TEntity>() where TEntity : Entity
{
return (Expression<Func<TEntity, bool>>)dict[typeof(TEntity)];
}
public LambdaExpression Predicate(Type entityType)
{
return dict[entityType];
}
internal void Add<TEntity>(Expression<Func<TEntity, bool>> predicate) where TEntity : Entity
{
dict.Add(typeof(TEntity), predicate);
}
}
public class LoadEntityQuery : IQuery<LoadEntityQueryResult>
{
public EntityPredicateDictionary Entities { get; private set; }
public LoadEntityQuery()
{
Entities = new EntityPredicateDictionary();
}
public void Add<TEntity>(Expression<Func<TEntity, bool>> predicate = null) where TEntity : Entity
{
Entities.Add(predicate);
}
}
// then to access the predicates
LoadEntityQuery query = ...;
var pred1 = query.Entities.Predicate<Entity1>();
var pred2 = query.Entities.Predicate(typeof(Entity2));

263740 | I have a web view which request one web page, now that web has some action events which may reply to IOS app as HTML or json. So how would the app will come to know the response type sent. So that the response is handled within the app.
Reading of static HTML content in webview using its delegate is what i have tried, when it is dynamic then how can one handle.
code logic:-
1. ON load of controller, request page with URL(something) in web view, user will interact
2. check response type if JSON then 4 else 3
3. load web page with different URL
4. Deserialize the JSON Data and store in native DB | **Method 1**
First, You need to set and handle the `UIWebView` delegate methods in your `UIViewController`
Then, in `webView: shouldStartLoadWithRequest: navigationType:` method, use the following
```
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
NSError *error;
NSString *responseString = [NSString stringWithContentsOfURL:request.URL
encoding:NSASCIIStringEncoding
error:&error];
//Parse the string here to confirm if it's JSON or HTML
//In case of JSON, stop the loading of UIWebview
if(json) {
retrun NO;
}
return YES;
}
```
**Note:** This will take a performance hit in case of HTML content as the response will be loaded 2 times. Once in `stringWithContentsOfURL` method and second time when the web view loads.
**Method 2**
To avoid the double loading you can let the web view load, irrespective of the content type. And then get the loaded content in `webViewDidFinishLoad` method.
*For this you may need to perform some changes on the server end as well.*
Suppose your HTML page with JSON is structured as :
```
<html>
<body>
<div id="json" style="display: none">{"jsonvalue":"{{result}}"}</div>
</body>
</html>
```
Then in `webViewDidFinishLoad`
```
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
NSString *res = [webView stringByEvaluatingJavaScriptFromString:@"document.getElementById('json').innerHTML"];
//Use the JSON string as required
}

Pardon me for posting a large program here. | A Python program is executed from top to bottom, so you need to define the function before you use it. A common alternative is putting all the code that is automatically executed in a `main` function, and adding at the bottom of the file:

main()

**UPDATE** *(see my answer for the fixed webpack.config)*
I give a try to the DLL webpack plugin suggested by @jpwiddy by compiling angular in a separate build, in order to have to rebuild only the application code during developments and gain considerable time of compilation.
However, after an inspection of the output JS, the file size is quite the same and there is still angular code inside.
Here is the new webpack config file for angular sources :
```
var webpack = require('webpack');
module.exports = {
entry: {
angular:[
'@angular/platform-browser',
'@angular/platform-browser-dynamic',
'@angular/core',
'@angular/common',
'@angular/compiler',
'@angular/http',
'@angular/router',
'@angular/forms'
]
},
output: {
filename: 'ng2.dll.js',
path: __dirname + '/build/',
library: 'ng2'
},
plugins: [
// Fixes angular 2 warning
new webpack.ContextReplacementPlugin(
/angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/,
__dirname
),
new webpack.DllPlugin({
name: 'ng2',
path: __dirname + '/build/ng2.json'
})
]
}
```
And the updated webpack config for application :
```
var webpack = require('webpack');
var LiveReloadPlugin = require('webpack-livereload-plugin');
module.exports = {
entry: __dirname + '/assets/app/app.ts',
output: {
filename: 'myApp.bundle.js',
path: __dirname + '/build/'
},
// Turn on sourcemaps
devtool: 'source-map',
resolve: {
extensions: ['.ts', '.js']
},
plugins: [
new LiveReloadPlugin({
appendScriptTag: true
}),
// Fixes angular 2 warning
new webpack.ContextReplacementPlugin(
/angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/,
__dirname
),
new webpack.DllReferencePlugin({
context: __dirname + '/build/',
manifest: require(__dirname + '/build/ng2.json')
})
],
module: {
rules: [{
enforce: 'pre',
test: /\.js$/,
loader: "source-map-loader"
},
{
enforce: 'pre',
test: /\.tsx?$/,
use: "ts-loader"
}
]
}
}
```
Here is one of the angular code I found in my application JS output :
```
_TsEmitterVisitor.prototype.visitBuiltintType = function (type, ctx) {
var typeStr;
switch (type.name) {
case __WEBPACK_IMPORTED_MODULE_2__output_ast__["R" /* BuiltinTypeName */].Bool:
typeStr = 'boolean';
break;
case __WEBPACK_IMPORTED_MODULE_2__output_ast__["R" /* BuiltinTypeName */].Dynamic:
typeStr = 'any';
break;
case __WEBPACK_IMPORTED_MODULE_2__output_ast__["R" /* BuiltinTypeName */].Function:
typeStr = 'Function';
break;
case __WEBPACK_IMPORTED_MODULE_2__output_ast__["R" /* BuiltinTypeName */].Number:
typeStr = 'number';
break;
case __WEBPACK_IMPORTED_MODULE_2__output_ast__["R" /* BuiltinTypeName */].Int:
typeStr = 'number';
break;
case __WEBPACK_IMPORTED_MODULE_2__output_ast__["R" /* BuiltinTypeName */].String:
typeStr = 'string';
break;
default:
throw new Error("Unsupported builtin type " + type.name);
}
ctx.print(typeStr);
return null;
};
```
Did I missed something in the new config to prevent webpack including angular sources in the output ?
Thank you | One great way I've personally done that has sped up the Webpack build process is implementing DLLs within your build.
Webpack works by analyzing your code for `require`s and `import`s, and then builds a table from these statements of all of your module dependencies and links to where those files can be found.
The DLL plugin improves on this, as when you register your dependencies with a DLL, every time those dependencies change (should be very infrequent), you build a DLL (made up of a javascript bundle and a JSON manifest file) and wraps all of those dependencies in a single package. That package is then referenced when pulling in those dependencies into the app.
A quick example:
```
entry: {
angular:[
'@angular/platform-browser',
'@angular/platform-browser-dynamic',
'@angular/core',
'@angular/common',
'@angular/compiler',
'@angular/http',
'@angular/router',
'@angular/forms'
],
bs: [
'bootstrap',
'ng-bootstrap'
]
},
output: {
filename: '[name].dll.js',
path: outputPath,
library: '[name]',
},
plugins: [
new webpack.DllPlugin({
name: '[name]',
path: join(outputPath, '[name].json')
})
]
```
... and then referenced as so -
```
{
plugins: [
new webpack.DllReferencePlugin({
context: process.cwd(),
manifest: require(join(outputPath, 'angular.json'))
}),
new webpack.DllReferencePlugin({
context: process.cwd(),
manifest: require(join(outputPath, 'bs.json'))
}),
]
}

264212 | I just set up SSH on my freeNAS server. However every time I connect I get kicked out right away. I get the following message:

264373 | I have the following class defined:
```
<TypeConverter(GetType(ExpandableObjectConverter))>
<DataContract()>
Public Class Vector3
<DataMember()> Public Property X As Double
<DataMember()> Public Property Y As Double
<DataMember()> Public Property Z As Double
Public Overrides Function ToString() As String
Return String.Format("({0}, {1}, {2})",
Format(X, "0.00"),
Format(Y, "0.00"),
Format(Z, "0.00"))
End Function
End Class
```
Using the `DataContractJsonSerializer` I receive the following JSON as expected:
```
{
"Vector": {
"X": 1.23,
"Y": 4.56,
"Z": 7.89
}
}
```
However, JSON.NET produces:
```
{
"Vector": "(1.23, 4.56, 7.89)"
}
```
If I remove the `ExpandableObjectConverter` attribute from the class, JSON.NET produces results as expected (same as DataContractJsonSerializer).
Unfortunately I need the `ExpandableObjectConverter` so that the class works with a property grid.
Is there any way to tell JSON.NET to ignore `ExpandableObjectConverters`?
I prefer to use JSON.NET instead of `DataContractJsonSerializer` because it is much easier to serialize enums to their string representations. | Although I appreciate Rivers' answer I am really looking for a solution that ignores all expandable object converters automatically (like the DataContractJsonSerializer does) rather than building a custom JsonConverter for each offending class.
I have found the following two solutions:
1. Use the built in DataContractJsonSerializer instead (at the expense of some other conveniences of JSON.NET).
2. Use a custom ExpandableObjectConverter (see below).
Since the default ExpandableObjectConverter supports converting to/from string, JSON.NET is serializing the class with a string. To counteract this I have created my own expandable object converter which does not allow conversions to/from string.
```
Imports System.ComponentModel
Public Class SerializableExpandableObjectConverter
Inherits ExpandableObjectConverter
Public Overrides Function CanConvertTo(context As System.ComponentModel.ITypeDescriptorContext, destinationType As System.Type) As Boolean
If destinationType Is GetType(String) Then
Return False
Else
Return MyBase.CanConvertTo(context, destinationType)
End If
End Function
Public Overrides Function CanConvertFrom(context As System.ComponentModel.ITypeDescriptorContext, sourceType As System.Type) As Boolean
If sourceType Is GetType(String) Then
Return False
Else
Return MyBase.CanConvertFrom(context, sourceType)
End If
End Function
End Class
```
Applying the above converter works flawlessly with JSON.NET and with the property grid control! |
266120 | So I am just tinkering with Lua after hearing that it was more versatile than python, so I tried to make a countdown to one year, in the form of DDD:HR:MN:SC. If anyone could give me an example it would be much appreciated! | You can use [`os.date`](https://www.lua.org/manual/5.3/manual.html#pdf-os.date) to retreive the current date as a table, then just build the difference by subtracting component-wise like this:
```lua
local function print_remaining(target)
local current = os.date("*t")
print(string.format("%i years, %i months and %i days",
target.year-current.year,
target.month-current.month,
target.day-current.day
))
end
local function countdown(target)
while true do
print_remaining(target)
os.execute('sleep 1')
end
end
countdown {year = 2019, month=12, day=25}
```
If you want it to be cooler, of course you'd have to adjust what components are shown depending on how much time is left.
---
Inspired by @csaars answer, I changed a few things and ended up with this
```lua
local function split(full, step, ...)
if step then
return math.floor(full % step), split(math.floor(full / step), ...)
else
return full
end
end
local function countdown(target)
local s, m, h, d = split(os.difftime(os.time(target), os.time()), 60, 60, 24)
print(string.format("%i days, %i:%i:%i", d, h, m, s))
if os.execute('sleep 1') then
return countdown(target)
end
end
countdown {year = 2019, month=12, day=25}
```
The `plit` function is a bit more complex than it needs to be for this example, but I thought it'd be a nice chance to showcase how nicely some things can be expressed with variadic recursive functions in Lua. |

Create a simple module and add a helper class then call it in your phtml file.
You can use Category's `CollectionFactory` class and select all attributes by using a `star (*)` symbol in `addAttributeToSelect` method. You can try this code example in your helper class.
```
protected $_categoryFactory;
public function __construct(
// ...
\Magento\Catalog\Model\ResourceModel\Category\CollectionFactory $collecionFactory,
) {
// ...
$this->_categoryFactory = $collecionFactory;
}
public function yourFunctionName()
{
$catId = 5; // category id
$collection = $this->_categoryFactory
->create()
->addAttributeToSelect('*')
->addAttributeToFilter('entity_id',['eq'=>$catId])
->setPageSize(1);
$catObj = $collection->getFirstItem();
$catData = $catObj->getData(); // dump this line to check all data
// ...
return $catObj->getPopularCategory();
}
```
Call the helper method in your phtml file.
```
$helper = $this->helper('{Vendor}\{Module}\Helper\Data');
$values = $helper->yourFunctionName();
```
**Using Object Manager (Not Recommended)**
```
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$catId = 5; // category id
$collection = $objectManager->create('Magento\Catalog\Model\ResourceModel\Category\CollectionFactory')
->create()
->addAttributeToSelect('*')
->addAttributeToFilter('entity_id',['eq'=>$catId])

267590 | I'm trying to set my own **stopword list** for MySQL (5.1.54) fulltext index, but encountered problems with configuration. I tried the following steps:
1. I did set system variable in */etc/mysql/my.cnf* by adding line:
```
ft_stopword_file = "/home/buli/stopwords.txt"
```
2. I created file */home/buli/stopwords.txt* with words that should be ignored

My problem is that I want to update the content of the `Textbox1`control but it doesn´t work. It writes perfectly the output into the console with the line `Console.WriteLine(alternative.Transcript);` but not into my textbox.
If someone could help I would appreciate so much his help. | The problem is that you're using `Task.Run`, which means your code will be running on a thread-pool thread.
Instead of calling `Task.Run()`, just move that code into a separate async method:
```
async Task DisplayResponses(IAsyncEnumerator<StreamingRecognizeResponse> responses)
{
while (await responses.MoveNext(default(CancellationToken)))
{
foreach (var result in responses.Current.Results)
{
foreach (var alternative in result.Alternatives)
{
Textbox1.Text = alternative.Transcript;
}
}
}
}
```
Then call that method *directly* (without `Task.Run`) from code that's already on the UI thread (e.g. an event handler).
The async machinery will make sure that after the `await` expression, you're back on the UI thread (the same *synchronization context*). So the assignment to the `Text` property will occur on the UI thread, and all should be well.
For example:
```
// This would be registered as the event handler for a button
void HandleButtonClick(object sender, EventArgs e)
{
var stream = client.StreamingRecognize();
// Send the initial config request
await stream.WriteAsync(...);
// Presumably you want to send audio data...
StartSendingAudioData(stream);
await DisplayResponses(stream.ResponseStream);
}

The first decimal point in which in this case is 3 from 2.34 should only change a maximum of one digit. Up or down randomly. The leading decimal points can change to anything in a random fashion.
What would be the best way of doing this? | ```
Random rand = new Random();
double x = ...;
x = ((int)(x*10) + rand.nextDouble()*2 - 1)/10.0;

Multiply by 10 and truncate to get the digits including the first decimal, add a random number between -1 and 1, scale back.
Note that your doubles will not have just 6 decimal digits; these numbers aren't decimal numbers. For output to show 6 decimals you'll need to format the number by using a format requesting 6 decimal digits. |

```
In the `composer.json` in the root of my Drupal codebase, I have this:
```
"extra": {
...
"merge-plugin": {
"include": [
"core/composer.json",
"modules/custom/my_yamm3/composer.json"
],
...
```
I updated my codebase with this commands:
```
$ composer update
$ composer dumpauto
```
And I noticed this line in composer's output:
```
> Drupal\Core\Composer\Composer::vendorTestCodeCleanup
- Installing geedmo/yamm3 (1.1.0): Loading from cache
```
Which is confirmed by an examination of the filesystem:
```
$ ls vendor/geedmo/yamm3/
bower.json composer.json demo/ gulpfile.js index.html LICENSE.txt package.json README.md yamm/
```
I've enabled the `my_yamm3` module on my site, and under `admin/config/development/performance`, I've disabled css aggregation.
However, when I load the page, I do not see the yamm libraries being loaded in the network tab in my browser.
Am I using the correct method to load a third-party css library? What am I doing wrong?
**EDIT** osman asked for some confirmation of the state of my environment. In my drupal project root, while I do have `/composer.json` and the directories `/drush/` and `/vendor/`, I don't have `/scripts/` nor `/web/`. I guess that means I am not using the `drupal-composer/drupal-project` project.
Regarding his recommended additions to `composer.json`, this is what I had:
```
"extra": {
"installer-paths": {
"core": ["type:drupal-core"],
"modules/contrib/{$name}": ["type:drupal-module"],
"profiles/contrib/{$name}": ["type:drupal-profile"],
"themes/contrib/{$name}": ["type:drupal-theme"],
"drush/contrib/{$name}": ["type:drupal-drush"],
"modules/custom/{$name}": ["type:drupal-custom-module"],
"themes/custom/{$name}": ["type:drupal-custom-theme"]
}
},
```
So again it looks like I don't have the composer project? | **Fundamentals**
To bind a CSS library into your Drupal installation, it should be defined and exposed via a \*.libraries.yaml file.
For example (taken from core's classy theme):
```
book-navigation:
version: VERSION
css:
component:
css/components/book-navigation.css: {}
```
defines that there is a library called `book-navigation` that when included in a page will deliver the `css/components/book-navigation.css` css file.
**Using composer with 3rd-party CSS libraries**
Composer works easily and reliably for PHP dependencies, using the `merge-plugin` in the way you started working in the OP. But, CSS and Javascript libraries, especially when some preprocessing or building step is required, are a different story.
This is an open and unsolved (to my knowledge and to the date) problem, you can read this issue to get an idea of what problems arise:
* <https://www.drupal.org/project/drupal/issues/2873160>
The main problem is, that when you import the library as a composer dependency, as you did, the library is installed inside the `vendor` directory **wherever** that is located. So, you cannot assume much inside your \*libraries.yaml file about the file path to the CSS/JS file(s) you want to use.
**Alternative (A) without composer: using CDN / externally hosted libraries definitions**
For you case, and taken that you want to include this file:
```
https://raw.githubusercontent.com/geedmo/yamm3/master/yamm/yamm.css
```
you could define it inside your \*libraries.yaml file as an externally hosted library (see [#external](https://www.drupal.org/docs/8/creating-custom-modules/adding-stylesheets-css-and-javascript-js-to-a-drupal-8-module#external)):
```
my_module.yamm3:
remote: https://raw.githubusercontent.com/geedmo/yamm3/master/yamm/yamm.css
version: VERSION
license:
name: MIT
url: https://github.com/geedmo/yamm3/blob/master/LICENSE.txt
gpl-compatible: true
css:
theme:
https://raw.githubusercontent.com/geedmo/yamm3/master/yamm/yamm.css : { type: external }
```
N.B.: This approach should always deliver the latest `yamm.css` version.
**Alternative (B) without composer: keeping a local copy in your own module's folder**
If you place the CSS file inside your module's folder, e.g. `css/yamm.css`, you will be able to use the following yaml definition in your \*.libraries.yaml file in order to be able to use it:
```
my_module.yamm3:
version: VERSION
css:
theme:
css/yamm.css : {}
```
**Attaching a library to page(s)**
Finally, after you are done defining your library, you can start using it.
This is documented extensively here (<https://www.drupal.org/docs/8/creating-custom-modules/adding-stylesheets-css-and-javascript-js-to-a-drupal-8-module>) and I would recommend reading that if you haven't already.

271895 | The official display has a 5 pin header marked "GPIO".
One pin is marked "5V" and appears to be a power output. However, it is not connected directly to the 5V rail of the board which is available on the "PWR OUT" USB connector. Instead it is connected to the collector pin of Q2. What is the intended purpose of this pin, and why is it not connected directly to the 5V rail? What is the function of Q2, and where does this 5V supply actually come from? The voltage on this pin appears to be a few mV higher than that of the PWR OUT connector. Why?
Two of the pins are marked SDA and SCL, and they are connected to the same I2C bus that is available on the DSI connector. Why are they duplicated?
Finally there is the INT pin. This is not available on the DSI connector. What does it do?
Edit: Also, why is the unit supplied with a four pin dupont cable? | The I2C ports are duplicated because older models do not have an I2C port on the DSI connector:
>
> The DSI connector on Model A/B boards does not have the I2C connections required to talk to the touchscreen controller and DSI controller.

* <https://www.raspberrypi.org/documentation/hardware/display/>
This explains why the I2C pins are duplicated and what the cable is for.
The 5V GPIO pin is separated from the main 5V supply by this small circuit:
[](https://i.stack.imgur.com/KA0y2.jpg)
U5 is a voltage detector. When the board is powered it waits for a short amount of time before switching on Q3, which powers up the GPIO 5V line as well as the display backlight power circuit. I am still not sure why the GPIO 5V has this but the USB PWR OUT does not.
The INT line is connected to PC7 of the ATTINY88 chip. This chip controls the backlight brightness and also seems to be connected to the touch screen controller, so it is probably passing through the touch interrupt. That doesn't make any sense at all, but I don't know what else it could be. |

I want to make use of the LV called "data" but I don't know how to create a filesystem on this since there is no path associated. Is there another LVM command I need to map this to a device? | The `data` LV appears to be a [thinpool LV](https://pve.proxmox.com/wiki/Storage:_LVM_Thin). It's an additional layer between the VG and the final LV. It allows additional features (eg: overprovisionning or also efficient copy-on-write where performances don't decrease the more additional snapshots are made).
There's plenty of documentation available about it. For example the [lvmthin(7)](https://manpages.debian.org/lvm2/lvmthin.7) manpage describing the feature:
>
> Blocks in a standard lvm(8) Logical Volume (LV) are allocated when the
> LV is created, but **blocks in a thin provisioned LV are allocated as
> they are written**. Because of this, a thin provisioned LV is given a
> virtual size, and **can then be much larger than physically available
> storage**. The amount of physical storage provided for thin provisioned
> LVs can be increased later as the need arises.
>
>
> Blocks in a standard LV are allocated (during creation) from the
> Volume Group (VG), but blocks in a thin LV are allocated (during use)
> from a special "thin pool LV". The thin pool LV contains blocks of
> physical storage, and blocks in thin LVs just reference blocks in the
> thin pool LV.
>
>
> **A thin pool LV must be created before thin LVs can be created within
> it**. A thin pool LV is created by combining two standard LVs: a large
> data LV that will hold blocks for thin LVs, and a metadata LV that

>
>
>
It's kept hidden under the hood, but the large data LV is `data_tdata` and the metadata LV is `data_tmeta`. To display them you can use `lvs --all` or `lvdisplay --all` (which will show `Internal LV Name`, telling it's not for direct use), but you can also forget about it, it's not really needed to know about this.
Anyway to use them, there's also a lot of documentation available around. For example at [Redhat](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_logical_volumes/assembly_thinly-provisioned-logical-volumes_configuring-and-managing-logical-volumes "RHEL8 - Chapter 12. Creating and managing thinly-provisioned logical volumes (thin volumes)"):
>
> The following command uses the `-T` option of the `lvcreate` command to create a thin volume named thinvolume in the thin pool `vg001/mythinpool`. Note that in this case you are specifying virtual size, and that you are specifying a virtual size for the volume that is greater than the pool that contains it.
>
>
>
> ```
> # lvcreate -V 1G -T vg001/mythinpool -n thinvolume
>
> ```
>
>
So in your case to create a 100 terabytes thin provisionned logical volume (to show off the over-provisioning feature):
```
lvcreate -V 100T -T pve/data -n bigthinvolume
```
It will then be usable like other LVs, with slight differences when it comes to advanced features like snapshots.
Be careful with overprovisionning, once data% (or more rarely meta%), as displayed with [`lvs`](https://manpages.debian.org/lvm2/lvs.8) reaches 100% on a thinpool, any write that causes block allocation will fail, resulting in an I/O error in the layer above (the thin LV): you must increase available real size before this ever happens.
On a Debian-based system, the package [`thin-provisioning-tools`](https://packages.debian.org/stable/thin-provisioning-tools) should probably be installed, it might be needed to handle some thin provisioning advanced features, including at boot. I don't know where this applies with Proxmox. |

273676 | Dears,
I am at very pressed situation :-(
I started to learn Javascript some months ago and I have written some pages for amusements of my invalid niece to her birthday this Friday. Separate pages are OK. But I feel calamitous that I am still unable to set php including. I have two earlier websites with php code that runs very well so I used to copy the code from those to my new index.php. Of course, I changed the name of folder and names of files. My two websites have menu and submenus, my new website has only menu without submenu, but every file has its own folder.
I quickly translated it to English and made it shorter but principle is the same. I tried:
```
<?php
$x = isset($_GET['x']) ? $_GET['x'] : 'hello';
if (isset($x) && preg_match('/^[a-zA-Z0-9_-]+$/', $x)) {
if (file_exists ("../pokus/".$x.".php")) {
include "../pokus/".$x.".php";
} else {
include (__DIR__)."/404.php";
}
}
?>
```
but allegedly the files "was not found on this server." Naturally, they are all of them uploaded to my server.
My HTML code:
```
<ul>
<li>
<a href="/hello/"<?php echo $x == "hello" ? 'class="choice"' : '';?>>
<img src = "pictures/hello.jpg" width = "320" height = "240">
</a>
</li>
<li>
<a href="/folder1/file1/" <?php echo $x == '../file1' ? 'class="choice"' : '';?>>
<img src = "pictures/pict1-menu.jpg" width = "320" height = "240">
</a>
</li>
<li>
<a href="/folder2/file2/" <?php echo $x == '../file2' ? 'class="choice"' : '';?>>
<img src = "pictures/pict2-menu.jpg" width = "320" height = "240">
</a>
</li>
<li>
<a href="/folder3/file3/" <?php echo $x == '../file3' ? 'class="choice"' : '';?>>
<img src = "pictures/pict3-menu.jpg" width = "320" height = "240">
</a>
</li>
</ul>
```
At folder called pokus I have index.php and hello.php (= some sentences to her birthday). Then I have subfolder folder1 and file1.php inside, subfolder folder2 and file2.php inside etc. I am forced to use many subfolders because each subfolder contains many pictures A1.jpg, A2.jpg ... D4.jpg using JS FOR cycle and therefore it is unable to mix them together.
I am very astonished that not even file hello.php sitting beside index.php I am not able to load. My Apache says that this file "was not found on this server." But the file hello.php is loaded immediately with opening index.php! Why is Apache so paranoid?
Here is live illustration: <http://pokus.zlatberry.cz/>

2. Use Promise
Promise.all(getManufactures(), getColors()).then([manufactures, colors] => {
getCars(manufactures, colors))
}
3. Separate the logic of calling API (getCars), use eventHandler to call that logic `onColorChange`, `onManufactureChange`
4. Use local state to handle data while filtering as you may not use this data in any other places. |

274353 | *Sorry for being such a novice.*
For this question I used C language, and the libraries stdlio.h and stdlib.h.
---
Question
--------
So a question is asking me to:
1. Open a text file named 'numbers.txt' in read mode. This text file
has 6 integers in it.
2. Read the 6 integers from that text file using a loop.
3. Calculate and display the total and average of those 6 integers.
The text file 'numbers.txt' holds the integers: 5, 10, 15, 20, 25.
Here's my code:
```
FILE *n;
n = fopen("numbers.txt", "r");
int a, num, sum = 0;
float avg;
for (a = 0; a < 6; a++) {
fscanf(n, "%d", &num);
sum = sum + num;
}
avg = sum / (a - 1);
printf("Sum = %d\nAverage = %.2f\n\n", sum, avg);
fclose(n);
```
Another variation of the question is that I need to use a while loop to read the integers in the text file.
Here's my code for that:
```
FILE *n;
n = fopen("numbers.txt", "r");
int a = 0, num, sum = 0;
float avg;
while (fscanf(n, "%d", &num) != EOF) {
fscanf(n, "%d", &num);
sum = sum + num;
a++;
}
avg = sum / a;
printf("Sum = %d\nAverage = %.2f\n\n", sum, avg);
fclose(n);
```
---
Problem
-------
When I run each of the above programs, I expect this output:
```
Sum = 75
Average = 15.00
```
However I get this instead (for the first code):
```
Sum = 100
Average 20.00
```
And this (for the second code):
```
Sum = 55
Average = 18.00
```
How am I able to get the correct output from both of these programs?
*Again I apologise for how basic this question is. Nonetheless, any help would be appreciated.* | In your word counting code, you are using the variable `content` which holds all of the users inputted lines in a list of lists. In your letter counting code, you use the variable `line` which is just the last line the user entered. Since that line must be "." to leave the loop it never has any letters thus you always return 0. Apply your letter counting technique to each word from word list like:
```
letter = sum(c.isalpha() for word in words_list for c in word)
``` |
274403 | I would like to read a text file into an array of strings using System.IO.File.ReadAllLines. However, ReadAllLines strips out some odd characters in the file that I would like to keep, such as chr(187). I've tried some different encoding options, but that doesn't help and I don't see an option for "no encoding."
I can use FileOpen and LineInput to read the file without modification, but this is quite a bit slower. Using FileSystemObject also works properly, but I would rather not use that.
What is the best way to read a text file into an array of strings without modification in .net? | There's no such concept as "no encoding". You *must* find out the right encoding, otherwise you can't possibly interpret the data correctly.
When you say "chr(187)" what Unicode character do you mean?
Some encodings you might want to try:
* Encoding.Default - the system default encoding
* Encoding.GetEncoding(28591) - ISO-Latin-1
* Encoding.UTF8 - very common in modern files |
275535 | I want build a form using a block module in `Drupal 8`. I am aware of building the forms in `Drupal` 7 but the same seems to be different in Drupal 8.
Request anyone who has worked on drupal8 custom forms as block to help me. | Your question is very vague, as I don't know how much you already know about modules, forms and blocks in Drupal 8. So here is a small guide what to do, further information on how to do stuff in detail would be overkill for this answer.
**1. Create a new module and enable it**
Look here: [Naming and placing your Drupal 8 module](https://www.drupal.org/node/2116781).
Basically you create the module folder and the module info yml file to let Drupal know about the module. Then you enable it using drush or the admin area in Drupal.
**2. Create the form**
Look here: [Introduction to Form API](https://www.drupal.org/node/2117411).
under `your_module/src/Form` you create the form. More details in the link above.
**3. Create the block and render the form**
Look here: [Create a custom block](https://www.drupal.org/node/2101565).
under `your_module/src/Plugin/Block/` you create the block which will render the form.
The idea is basically (code updated with suggestion from Henrik):
```
$builtForm = \Drupal::formBuilder()->getForm('Drupal\your_module\Form\YourForm');
$renderArray['form'] = $builtForm;
return $renderArray;
```
Note: You don't need to wrap the `$builtForm` with the `$renderArray`, you can return just the `$builtForm` and be fine. I just personally like to do it that way, because often times I need to add something else to the final render array like some markup, cache settings or a library etc.
**4. Place the block**
Place the block in the desired region(s). Done. |

276270 | I want to backup some filesystem folders from a client to an external server. My goal is to have a secure backup on the external server even if the client gets compromised/hacked in any way.
I am considering the following techniques (prio in that order):
* rsync
* aws S3
* sFTP
* HTTPs
AFAIK rsync and sFTP transmit over SSH and therefore I need to put some sort of SSH key on the client. If an attacker gets access to the client, he could also read the SSH key and connect to the external backup server. This is what I want to prevent.
AWS s3 permission model (<https://docs.aws.amazon.com/AmazonS3/latest/dev/acl-overview.html>) has a WRITE permissions which "Allows grantee to create, overwrite, and delete any object in the bucket". So a compromised client could delete all of my backups. Not suted in that scenario.
With HTTPs there are of course also credentials stored on the client, but I would create some sort of API on the external system only allowing to POST/Upload data. So an attacker could "only" upload "bulk" data onto the external server, and not e.g. delete my stored backups over SSH. But performing backups via HTTPs sounds like the wrong tool for the job.
Am I missing something obvious?
Any recommendations are highly appreciated. | The way that I handle this is to move control of the data to the *backups* destination. For the purposes of this description, *production* is your production (main) machine and *backups* is the backup server. This does require that you have a *backups* server rather than just a data repository, though.
* Remove ssh equivalence from between *production* and *backups* unless you protect the keys with a password. (This removes any opportunity for someone or something to get from one to the other.) DO NOT use the same password on both systems!
* Set up `rsyncd` on *production* with a read-everything but read-only configuration protected by username/password. Consider denying any access to `~/.ssh` directories - particularly root's
* Create a regular `rsync` job on *backups* to pull data from the *production* server. I couple this with `rsnapshot`, and actually to save space I run the entire set of backups on top of [S3QL](http://www.rath.org/s3ql-docs/) (hung off local disk rather than S3 storage).
This will stop a break-in on *production* getting to your *backups* data. It will also stop a break-in on *backups* overwriting your *production* system.
The downside of this as described is that `rsyncd` only delivers data in-the-clear. There are two options to handle this, as I wouldn't recommend clear text data transfer for any trans-Internet communication
* `stunnel`, which can be configured to present an SSL socket on behalf of `rsyncd`
* a point-to-point VPN tunnel using something such as as Wireguard, OpenVPN or IPsec.
I should point out that although this solution is Linux-centric, I do have `rsyncd` running on Windows systems, too, successfully backing up user data. The caveat here is that it's not easy to backup data from open files without using a VSS shadow snapshot, and `rsyncd` doesn't know how to create those. |
276275 | I have a dialog where users allocate product on an order to various available lots of product.
So basically if there are 100 units on a line item of an order, the user would have to allocate this quantity out to the available lots of product in a warehouse. This part of the design will work well. The part I am having problem designing is the returns.
Consider that weeks later, some product may be returned for one reason or another. I would like the user to be able to go back to this allocation dialog and input the return in some way. The return would have to be specific to a certain lot of product, so I have considered putting an extra column of inputs labeled Returns next to the Quantities column.
Here's the issue however. Will the user assume that any amount entered in the Returns column will have to be removed from the original Quantity column manually? Or will they assume that they should enter the Return amount and leave the originally entered quantity alone? I could design it to behave either way, but I am trying to think of other ways to make sure that they expect it to behave the way that it actually does behave. Perhaps automatically subtracting from the quantity column when they enter an amount into the returns column (this would probably cause other problems however...)?
I thought of making the quantity column readonly after the requested pickup date has passed, but am worried about what if they are editing the order quantities after the pickup date due to a mis-ship or other exception case. What do you think? Any ideas on making this UI better? | Keep in mind that the user interface for returns doesn't have to be a modified version of the interface you show above. Maybe a specialized returns interface would be a better way to go? |
276394 | Python 3
Consider the following two code samples.
Two questions:
1: What is the difference between the two approaches? For what benefit would I implement A versus B?
2: In sample A, is the self variable prefix required?
Sample A:
```
class DoSomething():
self.dispatcher = {
'SaveToS3': self.savetos3,
'SendWebHook': self.webhook,
'AddToQueue': self.addtoqueue,
'SendSms': self.sendsms,
'SendEmail': self.sendemail,
}
def __init__(self):
pass
```
Sample B:
```
class DoSomething():
def __init__(self):
self.dispatcher = {
'SaveToS3': self.savetos3,
'SendWebHook': self.webhook,
'AddToQueue': self.addtoqueue,
'SendSms': self.sendsms,
'SendEmail': self.sendemail,
}
``` | 1. In Sample A, `dispatcher` is shared among all instances of the class, and so modifying it will modify `self.dispatcher` for every `DoSomething`. With Sample B, on the other hand, each instance gets a separate `self.dispatcher`, and modifying one will leave all of the others alone. Sample A also lets you access `DoSomething.dispatcher` without involving any instances, while this won't work in B.
2. `self.` is actually not allowed at "class level," as there is no "`self`" object defined there. |

You can convert many `If` statements using [`PiecewiseExpand`](http://reference.wolfram.com/mathematica/ref/PiecewiseExpand.html):
```
If[Mod[n, 2] == 0, x[n - 1], y[n - 1]] // PiecewiseExpand
If[Mod[n, 2] == 0, r*x[n - 1] (1 - x[n - 1]), y[n - 1]] // PiecewiseExpand
```
The final code may look something like this:
```
r = 3;
x0 = 0.25;
RecurrenceTable[
{x[n] == Piecewise[{{x[n - 1], Mod[n, 2] == 0}}, y[n - 1]],
y[n] == Piecewise[{{r*x[n - 1] (1 - x[n - 1]), Mod[n, 2] == 0}}, y[n - 1]],
x[1] == x0,
y[1] == 0},
{x, y},
{n, 10}
]
```
```
{{0.25, 0.}, {0.25, 0.5625}, {0.5625, 0.5625}, {0.5625,
0.738281}, {0.738281, 0.738281}, {0.738281, 0.579666}, {0.579666,

```
A couple of related points:
1. It is best not to use capital letters for your symbol names, as these may conflict with built-in functions.
2. You may consider `Divisible[n, 2]` in place of `Mod[n, 2] == 0` if you wish. |

Thank you | One way to do this, is to make the SwitchViewController a custom container controller, and add either the table view or map view as its child. Here is an example that I've used before that has the same set up as your storyboard (my ContainerViewController is your SwitchViewController, and my controllers with the identifiers "InitialVC" and "substituteVC" would be your table view and map view).
This is code I have in the ContainerViewController,
```
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
UIViewController *initial = [self.storyboard instantiateViewControllerWithIdentifier:@"InitialVC"];
[self addChildViewController:initial];
[self.view addSubview:initial.view];
self.currentController = initial;
[self constrainViewEqual:self.currentController];
}
-(void)switchToNewView {
UIViewController *sub = [self.storyboard instantiateViewControllerWithIdentifier:@"SubstituteVC"];
[self addChildViewController:sub];
sub.view.frame = self.view.bounds;
[self moveToNewController:sub];
}
-(void)moveToNewController:(UIViewController *) newController {
[self.currentController willMoveToParentViewController:nil];
[self transitionFromViewController:self.currentController toViewController:newController duration:.6 options:UIViewAnimationOptionTransitionCrossDissolve animations:^{}
completion:^(BOOL finished) {
[self.currentController removeFromParentViewController];
[newController didMoveToParentViewController:self];
self.currentController = newController;
[self constrainViewEqual:self.currentController];
}];
}
```
constrainViewEqual is a category method that I use to set up the layout constraints for the views. It looks like this,
```
-(void)constrainViewEqual:(UIViewController *) vc {
[vc.view setTranslatesAutoresizingMaskIntoConstraints:NO];
NSLayoutConstraint *con1 = [NSLayoutConstraint constraintWithItem:self.view attribute:NSLayoutAttributeCenterX relatedBy:0 toItem:vc.view attribute:NSLayoutAttributeCenterX multiplier:1 constant:0];
NSLayoutConstraint *con2 = [NSLayoutConstraint constraintWithItem:self.view attribute:NSLayoutAttributeCenterY relatedBy:0 toItem:vc.view attribute:NSLayoutAttributeCenterY multiplier:1 constant:0];
NSLayoutConstraint *con3 = [NSLayoutConstraint constraintWithItem:self.view attribute:NSLayoutAttributeWidth relatedBy:0 toItem:vc.view attribute:NSLayoutAttributeWidth multiplier:1 constant:0];
NSLayoutConstraint *con4 = [NSLayoutConstraint constraintWithItem:self.view attribute:NSLayoutAttributeHeight relatedBy:0 toItem:vc.view attribute:NSLayoutAttributeHeight multiplier:1 constant:0];
NSArray *constraints = @[con1,con2,con3,con4];
[self.view addConstraints:constraints];
}
```
I call switchToNewView from a button in the initial view controller (the one you have labeled as ViewController) like this,
```
-(IBAction)doStuff:(id)sender {
ContainerController *cc = (ContainerController *)self.childViewControllers[0];
[cc switchToNewView];
}

In the above request i want to access the parameter `ride_transection_id` for finding particular transection object and also some other value as well.
So basically i have 3 way to do that.
**1.** i can use `@PathVariable`
```
@RequestMapping(value = "/end-ride", method = RequestMethod.POST)
public ResponseEntity<?> endRide(@PathVariable("ride_transection_id") long ride_transection_id,@RequestBody
SomeDTORequest someDTORequest ) {
//find transaction using path varibale
}
```
**2.**i can use `@RequestParam`
```
@RequestMapping(value = "/end-ride", method = RequestMethod.POST
public @ResponseBody item getitem(@RequestParam("ride_transection_id")
long ride_transection_id,@RequestBody SomeDTORequest someDTORequest ){
//find transaction using RequestParam varibale
}
```
3. i can use DTO Object `SomeDTORequest` and accept `ride_transection_id` into that with other value as well.
```
@RequestMapping(value = "/end-ride", method = RequestMethod.POST)
public ResponseEntity<?> endRide(@RequestBody SomeDTORequest someDTORequest ) {
//find transaction using path someDTORequest .getID()
```
}
i am little bit confuses.just want ask which is safest and right way to access the `ride_transection_id` ?
thanks | You can use any of them but every way is designed for a certain use.
Path variable:
is used when you need to access an entity using a certain field for example i want to access an order and this order is defined by id so to access this order i need the following request `Get /order/{id}`
Request Parameter:
when you want to send a specific variable or flag for a certain method
for example `Get /orders?is_shipped=true`, so this will get all shipped orders or you may need orders at certain page `Get /orders?page=1`
Request body:
when you need to update the entity by the put or patch request as you will update the entity using the entity's json representation which can be send through the request body
for example `PUT /orders/{id}`
body: `{"title": "order_1"}`
then the order with id {id} will be updated with the new title

277420 | I just installed Moblin Operating System. It's using GRUB2. On my Ubuntu 8.04 GRUB 0.97 was being used in which i was using the **default saved** option comfortably. I found that with GRUB2 i should not edit /boot/grub/menu.lst directly *but I did* :) because my Moblin does not contain any **/etc/default/grub** where they say I should do the modification I want.
So what I did is as following which did not work:
```
default=saved
timeout=1
#splashimage=(hd0,0)/boot/grub/splash.xpm.gz
#hiddenmenu
#silent
title Moblin (2.6.31.5-10.1.moblin2-netbook)
root (hd0,0)
kernel /boot/vmlinuz-2.6.31.5-10.1.moblin2-netbook ro root=/dev/sda1 vga=current
savedefault=1
title Pathetic Windows
rootnoverify (hd0,1)
chainloader +1
savedefault=0
```
By doing so I should have automatically switch between Moblin and Window at each boot but it's not working.
Almost all the troubleshooters on internet are saying that I should enable the **DEFAULT=save** option in **/etc/default/grub** but I am unable to find this file. Any idea what else should I do?
Thanks a lot
**Update:**
I used the equal to sign because by default my menu.lst had an entry as **default=0**. However, **default 0**, is also working fine.
Moreover the **menu.lst**, i have is actually a symbolic link to **./grub.conf**. I have also noticed that **grub-intall** and **grub-set-default** commands are not working. | The correct syntax for enabling `savedefault` in `/etc/default/grub` (GRUB 2) is with the lines:
```
GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true
```
and *not* with the line `DEFAULT=save` that the enquirer suggested.
After adding the two lines above to `/etc/default/grub`, one has to update GRUB's configuration, as a superuser, with the following commands:
```
grub-mkconfig
update-grub
```
At least on Lubuntu 12.10, `grub-mkconfig` is not needed (as it, without options, dumps the config file to stdout). The only needed command is `update-grub` which actually invokes `grub-mkconfig` with the proper `-o file` option. |

279313 | I'm not exactly sure how to ask this question really, and I'm no where close to finding an answer, so I hope someone can help me.
I'm writing a Python app that connects to a remote host and receives back byte data, which I unpack using Python's built-in struct module. My problem is with the strings, as they include multiple character encodings. Here is an example of such a string:
"^LThis is an example ^Gstring with multiple ^Jcharacter encodings"
Where the different encoding starts and ends is marked using special escape chars:
* ^L - Latin1
* ^E - Central Europe
* ^T - Turkish
* ^B - Baltic
* ^J - Japanese
* ^C - Cyrillic
* ^G - Greek
And so on... I need a way to convert this sort of string into Unicode, but I'm really not sure how to do it. I've read up on Python's codecs and string.encode/decode, but I'm none the wiser really. I should mention as well, that I have no control over how the strings are outputted by the host.
I hope someone can help me with how to get started on this. | There's no built-in functionality for decoding a string like this, since it is really its own custom codec. You simply need to split up the string on those control characters and decode it accordingly.
Here's a (very slow) example of such a function that handles latin1 and shift-JIS:
```
latin1 = "latin-1"
japanese = "Shift-JIS"
control_l = "\x0c"
control_j = "\n"
encodingMap = {
control_l: latin1,
control_j: japanese}
def funkyDecode(s, initialCodec=latin1):
output = u""
accum = ""
currentCodec = initialCodec
for ch in s:
if ch in encodingMap:
output += accum.decode(currentCodec)
currentCodec = encodingMap[ch]
accum = ""
else:
accum += ch
output += accum.decode(currentCodec)
return output
```
A faster version might use str.split, or regular expressions.
(Also, as you can see in this example, "^J" is the control character for "newline", so your input data is going to have some interesting restrictions.) |
279803 | I have a list of hostnames / IP addresses, and my script takes the each item from the text file and stores them in the `nodes` variable as a list.
I want to ping each host and output the results to a text file. I can do it with a single host, but am having trouble understanding how to iterate through the list.
I have looked at other posts on Stackoverflow, but most of the posts are using the OS module, which has been deprecated.
**My code:**
```
#!/usr/local/bin/python3.6
import argparse
import subprocess
parser = argparse.ArgumentParser(description="Reads a file and pings hosts by line.")
parser.add_argument("filename")
args = parser.parse_args()
# Opens a text file that has the list of IP addresses or hostnames and puts
#them into a list.
with open(args.filename) as f:
lines = f.readlines()
nodes = [x.strip() for x in lines]
# Opens the ping program
ping = subprocess.run(
["ping", "-c 1", nodes[0]],
stdout=subprocess.PIPE,
stderr=subprocess.PIPE
)
# Captures stdout and puts into a text file.
with open('output.txt', 'w') as f:
print(ping.stdout.decode(), file=f)
f.close()
``` | You can iterate directly through your list of nodes like so:
```
with open(args.filename) as f:
lines = f.readlines()
nodes = [x.strip() for x in lines]
with open('output.txt', 'w') as f:
for node in nodes:
# Opens the ping program
ping = subprocess.run(
["ping", "-c 1", node],
stdout=subprocess.PIPE,
stderr=subprocess.PIPE
)
# Captures stdout and puts into a text file.
print(ping.stdout.decode(), file=f)
```
Note that you can also directly iterate over your input file, which is said to be more 'Pythonic' than using `readlines()`:
```
with open(args.filename,'r') as infile, open('output.txt', 'w') as outfile:
for line in infile:
node = line.strip()
# Opens the ping program
ping = subprocess.run(
["ping", "-c 1", node],
stdout=subprocess.PIPE,
stderr=subprocess.PIPE
)
# Captures stdout and puts into a text file.
print(ping.stdout.decode(), file=outfile)
```
Note that this is untested, but I can't see any obvious errors. |
280131 | net core web api application. I have configured swagger for my web api app. I am doing authentication and authorization from swagger and I do not have webapp or SPA.

281621 | I have a photo gallery on my site with 1M photos in it. There are 2 search tables associated with it. Table #1 contains a list of words used in the photos. Table #2 contains a list of what words match up with what photos. Table #2 is 7M rows. I am testing partitioning this 7M row table because I have another set of tables with 120,000,000 rows. Queries against the 120M row wordmatch table below, with or without a join again the wordlist table below, take multiple seconds to run.
I am trying to perform a join between these 2 tables and MySQL 5.6 EXPLAIN PARTITIONS shows it is using all the partitions. How can I redo this query to make this correctly use only a single partition?
The 2 tables:
```
CREATE TABLE wordlist (
word_text varchar(50) NOT NULL DEFAULT '',
word_id mediumint(8) unsigned NOT NULL AUTO_INCREMENT
PRIMARY KEY (word_text),
KEY word_id (word_id)
) ENGINE=InnoDB
CREATE TABLE wordmatch (
pic_id int(11) unsigned NOT NULL DEFAULT '0',
word_id mediumint(8) unsigned NOT NULL DEFAULT '0',
title_match tinyint(1) NOT NULL DEFAULT '0',
PRIMARY KEY (word_id,pic_id,title_match),
KEY pic_id (pic_id)
) ENGINE=InnoDB
/*!50100 PARTITION BY HASH (word_id)
PARTITIONS 11 */;
```
SQL query I am performing:
```
EXPLAIN PARTITIONS SELECT m.pic_id FROM wordlist w, wordmatch m WHERE w.word_text LIKE 'bacon' AND m.word_id = w.word_id
+----+-------------+-------+-----------------------------------+-------+-----------------+---------+---------+----------------------------+------+-------------+
| id | select_type | table | partitions | type | possible_keys | key | key_len | ref | rows | Extra |
+----+-------------+-------+-----------------------------------+-------+-----------------+---------+---------+----------------------------+------+-------------+
| 1 | SIMPLE | w | NULL | range | PRIMARY,word_id | PRIMARY | 52 | NULL | 1 | Using where |
| 1 | SIMPLE | m | p0,p1,p2,p3,p4,p5,p6,p7,p8,p9,p10 | ref | PRIMARY | PRIMARY | 3 | w.word_id | 34 | Using index |
+----+-------------+-------+-----------------------------------+-------+-----------------+---------+---------+----------------------------+------+-------------+
```
The join produces a query that uses all partitions.
If I retrieve the word\_id # first and go straight against the wordmatch table, everything is ok:
```
EXPLAIN PARTITIONS SELECT m.pic_id FROM wordmatch m WHERE m.word_id = 219657;
+----+-------------+-------+------------+------+---------------+---------+---------+-------+-------+-------------+
| id | select_type | table | partitions | type | possible_keys | key | key_len | ref | rows | Extra |
+----+-------------+-------+------------+------+---------------+---------+---------+-------+-------+-------------+
| 1 | SIMPLE | m | p9 | ref | PRIMARY | PRIMARY | 3 | const | 18220 | Using index |
+----+-------------+-------+------------+------+---------------+---------+---------+-------+-------+-------------+
```
How do I get this to work correctly?
I prefer not to split this into multiple queries if possible.
You may have noticed I am using LIKE above. People will often search on bacon% to get plurals of words, etc.
Example:
```
SELECT m.pic_id FROM wordlist w, wordmatch m WHERE w.word_text LIKE 'bacon%' AND m.word_id = w.word_id
```
I realize this wildcard search may result in 2 or more partitions being selected. This is probably ok, although if there is a way to change the partitioning to prevent that, I welcome any tips.
**Edit #1:** Added details as my original question was confusing. I was testing my 7M row table first before doing my 120M row table.
**Edit #2:** Resolution to my overall issue: My performance issues seem to be resolved as I partitioned my 120M row table into 101 partitions per this post: [MySQL performance: partitions](https://stackoverflow.com/questions/16721772/mysql-performance-multiple-tables-vs-index-on-single-table-and-partitions) I do not know if MySQL is going against all the partitions at runtime - Ollie Jones says it does not in the comments below and EXPLAIN PARTITIONS is incorrect - but it is fast now so I am happy. | To get your query working with efficient indexing is probably a good idea before you dive into the partitioning project. Here's your query refactored to use `JOIN`:
```
SELECT m.pic_id
FROM wordlist w
JOIN wordmatch m ON w.word_id = m.word_id
WHERE w.word_text LIKE 'bacon%'
```
This query can use a compound index on `wordlist (word_test, word_id)`. It will random-access the index for the first matching `word_text`, and then scan the index retrieving the `word_id` values until it gets to the last matching `word\_text.
It can also use your existing primary key on `wordmatch (word_id, pic_id)` It speeds up your query because the data base engine can satisfy your query directly from the index without having to bat the hard drive back and forth to the table itself.
So, give those indexes a try. Your large table, the `wordmatch` table, should work fairly well without partitioning. It's more common to partition tables that contain lots of content (like the text of articles) than it is to partition this kind of fixed-row-size join table.
Notice that your `EXPLAIN` announces it will look at all the partitions because `EXPLAIN` can't tell which partition (or partitions) your `w.word_text LIKE 'bacon%'` WHERE-clause will need to examine. `EXPLAIN` isn't as dumb as a box of hammers, but it is close. MySQL won't examine the partitions it doesn't need to, but it doesn't know which partitions are involved until runtime.
Have you considered using FULLTEXT search? It might simplify what you're doing. |
281756 | this must be possible via PowerShell as it can be done from Central Administration. I have a task to modify just the public URL of an existing alternate access mapping (AAM).
```
PS U:\> $aam = Get-SPAlternateURL -WebApplication http://mysite
PS U:\> $aam
IncomingUrl Zone PublicUrl
----------- ---- ---------
http://default.mysite Default http://default.mysite
http://mysite Internet http://mysite
```
So with the above AAM, in the Internet zone, I need to change the public URL to say `http://othermysite`
If I run
```
PS U:\> Set-SPAlternateURL -Identity http://mysite -Zone Internet -Url http://othermysite
```
I end up with both the public URL and Internal URL changed
```
PS U:\> $aam = Get-SPAlternateURL -WebApplication http://othermysite
PS U:\> $aam
IncomingUrl Zone PublicUrl
----------- ---- ---------
http://default.mysite Default http://default.mysite
http://othermysite Internet http://othermysite
```
As well, Set-SPAlternateURL does not provide an argument -Internal like the New-SPAlternateURL cmdlet.
If I run
```
PS U:\> New-SPAlternateURL -WebApplication http://default.mysite -Zone Internet -Url http://mysite -Internal
```
I get the correct aam, but I have two in the list of Internet zone aam now.
```
PS U:\> $aam = Get-SPAlternateURL -WebApplication http://default.mysite
PS U:\> $aam
IncomingUrl Zone PublicUrl
----------- ---- ---------
http://default.mysite Default http://default.mysite
http://othermysite Internet http://othermysite
http://mysite Internet http://othermysite
```
If I try to remove the aam
```
http://othermysite Internet http://othermysite
```
both aam for the Internet zone are removed.
So how can I get the following accomplished via PowerShell, or is this only possible via the GUI in Central Administration?
```
IncomingUrl Zone PublicUrl
----------- ---- ---------
http://default.mysite Default http://default.mysite
http://mysite Internet http://othermysite
``` | You need to do this in three steps as the IncomingURL and PublicURL are equal. Start by removing what you have on the internet zone (1) and build your url-structure starting with the PublicURL (2). When that's done - set a new URL for the IncomingURL (3).
```
#(1)
Remove-SPAlternateURL -WebApplication http://mysite -Zone "Internet"
#(2)
New-SPAlternateURL http://othermysite -Zone "Internet"
#(3)
New-SPAlternateURL http://mysite -Zone "Internet" -internal
```
Now you have what you wish for:
```
IncomingUrl Zone PublicUrl
----------- ---- ---------
http://mysite Internet http://othermysite
```
From this setting, you are able to set the publicURL since it differs from the IncomingURL:
```
Get-SPAlternateURL “http://othermysite” | Set-SPAlternateURL “http://newothermysite”
```
And the outcome will be
```
IncomingUrl Zone PublicUrl
----------- ---- ---------
http://mysite Internet http://newothermysite

284465 | I am a Maya user and I am currently writting an Auto-Rig.
I created different Classes for each major tasks of the tool. (ex: Class\_UI, Class\_Arms\_Rig, etc..)
The problem I have is that I can't call a method from "Class\_Joints" (the class that will generates every needed Joints) with my "Class\_UI"
Here are the codes :
First the Class\_UI
```
import sys
sys.path.append('G:\\3D2\\Script\\Auto_Rig')
import Class_Joints
import Class_Arms
import maya.cmds as mc
class Window_UI(object):
# Initializing global variables
def __init__(self):
# Getting acces to the different modules
self.Arms = Class_Arms.Arms_Rig()
self.Joints = Class_Joints.Gen_Joints()
# Create Ui
self.create_UI()
# Creating the UI
def create_UI(self):
# Create window
self.UI = mc.window(title='Auto-Rig Tool', w=(300), h=(350))
# Main layout
self.mainLayout = mc.menuBarLayout()
### Joints Option ###
# Create Joints Button
self.createJointsButton = mc.button(label='Create Joints', command=self.Joints.gen_arms_joints)
Window_UI()
mc.showWindow()
```
Then the Class\_Joints :
```
import maya.cmds as mc
class Gen_Joints:
# Creating arm Jnts and the list of it
def gen_arms_joints(self):
self.shoulderJnt = mc.joint(absolute=True, position=[5,8,0], n='L_Shoulder_Jnt')
self.elbowJnt = mc.joint(absolute=True, position=[10,8,-1.5], n='L_Elbow_Jnt')
self.wristJnt = mc.joint(absolute=True, position=[15,8,0], n='L_Wrist_Jnt')
self.handcupJnt = mc.joint(absolute=True, position=[18,8,0], n='L_HandCup_Jnt')
self.jntList = mc.ls(self.shoulderJnt, self.elbowJnt, self.wristJnt, self.handcupJnt)
```
When I run the `Class_UI` Code, the button within the UI is supposed to run the `gen_arms_joints` method within the `Class_Joints`
But I get this error message : `# Error: gen_arms_joints() takes exactly 1 argument (2 given) #`
I know that self is an implicit argument here but I do not know how to avoid this error.
Thank you all for your time.
:D
Cordially, Luca. | Two things i would recommend you do. I dont use Maya but i have built apps with multiple different GUIs.
1. Every GUI I've used when it comes to buttons is the first argument is a reference to self, and then there is usually 1 or 2 more arguments passed in. Some pass the reference to the button itself while others pass a argument that holds event details. My guess is this is what is happening. When you click the button it is passing in an "event" object that hold details about what was clicked and other details.
2. To truly find out what is passed change your function signature to this and see what is logged.
```
def gen_arms_joints(self, mystery_second_arg):
print(type(mystery_second_arg), mystery_second_arg)
self.shoulderJnt = mc.joint(absolute=True, position=[5,8,0], n='L_Shoulder_Jnt')
self.elbowJnt = mc.joint(absolute=True, position=[10,8,-1.5], n='L_Elbow_Jnt')
self.wristJnt = mc.joint(absolute=True, position=[15,8,0], n='L_Wrist_Jnt')
self.handcupJnt = mc.joint(absolute=True, position=[18,8,0], n='L_HandCup_Jnt')
self.jntList = mc.ls(self.shoulderJnt, self.elbowJnt, self.wristJnt, self.handcupJnt)

284548 | I am interested in creating new rows is SAS that are conditional on specific variables.
Suppose these are the names of the columns RecordID, ItemName, ItemCount, ItemX, ItemY, ItemZ.
ItemX, ItemY, and ItemZ are numeric variables that can be equal to or greater than 0.
When ItemX, ItemY, and/or ItemZ holds a value greater than 0, I want a new row to be created where ItemName contains the variable name (ItemX, ItemY, ItemZ) and ItemCount to contain the numeric value.
For example, if RecordNumber=1 has ItemX=5 and ItemY=10, then ItemName=ItemX and ItemCount=5 will appear in a new row. ItemName=ItemY and ItemCount=10 has its own row.
How should I go about this in SAS? Thanks. | Pretty easy:
```
data want(keep=ItemName ItemCount);
set have;
array items[3] itemx itemy itemz;
format ItemName $32. ItemCount best.;
do i=1 to 3;
if items[i] > 0 then do;
ItemName = vname(items[i]);
ItemCount = items[i];
output;
end;
end;
run;
```
Create an array of the item variables. Loop over that array. Check your condition. Use the `vname()` function to get the variable name and the `output` statement to create the output record. |

284927 | [This answer](https://aviation.stackexchange.com/a/47132) made me wonder if engines are stopped automatically after an emergency landing as soon as one of the exit doors are opened.
>
> (...) if the engine is still running, you're about to run forward into the area where you're at risk of being sucked into the running engine.

I'm not sure how high the risk would be to be sucked in or being blasted away by the jet-blast, I guess a lot of the emergency landings are because of engine failure so they aren't running anymore.
Maybe as an added extra - how long does it take for an engine to spin down to a safe RPM (so that it won't suck in people or blast them away)? | There is no automatic shutdown. However, shutting down the engines is part of the evacuation checklist done by the flight crew.
It's happened before that the controls link was severed and an engine could not be shutdown, such as in [Qantas Flight 32](https://en.wikipedia.org/wiki/Qantas_Flight_32).
>
> Upon landing, the crew were unable to shut down the No. 1 engine, which had to be doused by emergency crews until flameout was achieved.
>
>

Normally the captain would then instruct the cabin crew to not use that side of the plane. Same thing happens when there is a fire on one side, in that case the captain would also steer the plane so that the [good side is upwind](https://aviation.stackexchange.com/q/37104/14897).
Aircraft are tested to ensure all occupants can evacuate with 50% of the emergency exits not working (glass half-full: 50% of the doors working). See: [How are evacuation tests made as realistic as possible?](https://aviation.stackexchange.com/q/21160/14897)
About how long it takes for the engine to stop producing thrust, it's about 5 seconds. If there is no or little thrust, there is no suction to worry about. Also note that figure is for a spool down from full thrust (not from idle thrust, which is to be expected after landing).

285288 | I'm writing a utility Mac OS X app that basically acts as a web server accepting incoming HTTP requests (think of it as a mock REST API server). I want to be able to support HTTPS, but ideally I'd like to remove the requirement for my users to have to purchase their own SSL certificates.
I've been thinking a little on how I might achieve this. Let's say I register a domain called `myapp.com`. I then purchase an SSL cert for `myserver.myapp.com` that is signed by a registered CA. I ship my app with those SSL cert details embedded within it. All my users have to do is update their `/etc/hosts` file to point `myserver.myapp.com` to whatever IP address my app is installed and running on.
In fact, by far, the most common scenario would be my app running on the same machine as the client, so I'm considering updating the main DNS entry for `myserver.myapp.com` to point to `127.0.0.1`, and most users wouldn't have to change anything.
So, that's the basic theory. What have I missed that would make this an unworkable plan? A couple of things that have crossed my mind:
* I could use a self-signed cert. However, many SSL clients barf (or throw up warnings) if the cert doesn't have a valid CA chain. I'm happy to pay the money for a real cert to alleviate this inconvenience for my users.
* I would be embedding the private key for my SSL cert into my app. In theory, someone could extract that and use it to impersonate my app. I guess my reaction is "so what?" My app is a small productivity app, it isn't an e-commerce site. It doesn't collect sensitive info. It literally just simulates web server responses so devs can test their apps.
Any advice/feedback would be greatly appreciated. Thanks. | This won't work - but for nontechnical reasons.
Distributing an SSL certificate to your users along with its associated key will violate the issuance terms of your SSL certificate provider, and they will revoke the certificate when they discover what you have done. (This happened, for example, [when Pivotal tried to offer SSL service for developers through sslip.io](https://blog.pivotal.io/labs/labs/sslip-io-a-valid-ssl-certificate-for-every-ip-address).) This will, of course, cause your application to stop working.
If your users have administrative access to their machines, they can [create and trust their own self-signed CA using Keychain Access](https://support.apple.com/kb/PH20132?locale=en_US). Once they have done so, they could create a certificate (again, using Keychain Access) and insert that into your application to enable SSL. |
285926 | **Background on the machine I'm having a problem with:**
The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2-year-old to keep in touch with her grandparents and other members of the family - which everyone loves.
It has a DFI CM33-TL/G ATX (identified using SiSoft Sandra) motherboard hosting an Intel Celeron 1.3 GHz CPU, 768 MB PC133 SDRAM, a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board based on the NEC uPD720102 chipset containing three external and one internal USB sockets. It's also hosting a 1.44 MB floppy drive on FDD0, a new 80 GB Western Digital hard drive running as master on IDE0 and a Panasonic DVD+/-RW running as master on IDE1.
All this is sitting in a slimline case running off a Macron Power MPT-135 135 W Flex power supply.
The motherboard is running a version of Award BIOS 05/24/2002-601T-686B-6A6LID4AC-00. Could this be updated? If so, from where? I've raked through the manufacturer's website, but I can't find any hint of downloads for either drivers *or* BIOS updates.
The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover).
It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component.
The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website.
**The problem:**
If I hook any devices to the USB 2.0 sockets, it hangs the whole machine, and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover.
**Workarounds found:**
I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried three different kinds of USB thumb drives, three different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0, but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected.
**Attempted solutions:**
I've seen suggestions that this could be a power problem - that the PSU just doesn't have the power to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU power], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector, etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem?
If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher power than the current one? My interpretation was that the power only affected the number of drives you could hook up to the power connectors. Is that right?
I've installed the USB card in another machine, and it works without any issues, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it.
The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the Wi-Fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work?
**Other thoughts/questions:**
Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will *any* version of Award BIOS function in its place?
**Question:**
Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine? | I had all manner of problems on an older machine trying to use my iPod over USB through a cheap USB 2.0 PCI card I had. In the end, I chucked it and bought a more expensive one, and all the problems went away. I'd suggest trying that. I can't imagine that a USB 2.0 PCI card will cost much these days, but do what I did and buy the next one up from the cheapest one you can get. |
285959 | I want to have custom colors according to the mouse events (mouse enter, exit, pressed, etc). So to accomplish this, I wrote the code below. It is fine for everything, except in the case of the mouse pressed event, which does nothing.
It only works if I override the color in the `UIManager` like this `UIManager.put("Button.select", Color.red);`. The problem with the `UIManager` is that it will change for all my buttons.
Can anyone tell me what I might be doing wrong or what is the best approach to accomplish what I'm trying to do?
My Code:
```
final JButton btnSave = new JButton("Save");
btnSave.setForeground(new Color(0, 135, 200).brighter());
btnSave.setHorizontalTextPosition(SwingConstants.CENTER);
btnSave.setBorder(null);
btnSave.setBackground(new Color(3, 59, 90));
btnSave.addMouseListener(new MouseListener() {
@Override
public void mouseReleased(MouseEvent e) {
btnSave.setBackground(new Color(3, 59, 90));
}
@Override
public void mousePressed(MouseEvent e) {
// Not working :(
btnSave.setBackground(Color.pink);
}
@Override
public void mouseExited(MouseEvent e) {
btnSave.setBackground(new Color(3, 59, 90));
}
@Override
public void mouseEntered(MouseEvent e) {
btnSave.setBackground(new Color(3, 59, 90).brighter());
}
@Override
public void mouseClicked(MouseEvent e) {
btnSave.setBackground(new Color(3, 59, 90).brighter());
}
});
```
Edit1:
So, instead of `MouseListener`, I'm using `ChangeListener` and `ButtonModel` as suggested by mKorbel. With this code I'm still not observing any changes on mouse pressed in the button except when I press and drag outside the button. Any thoughts?
```
btnSave.getModel().addChangeListener(new ChangeListener() {
@Override
public void stateChanged(ChangeEvent e) {
ButtonModel model = (ButtonModel) e.getSource();
if (model.isRollover()) {
btnSave.setBackground(new Color(3, 59, 90).brighter());
} else if (model.isPressed()) {
btnSave.setBackground(Color.BLACK);
} else {
btnSave.setBackground(new Color(3, 59, 90));
}
}
});

Is there something horribly simple I'm missing? All the other related questions to this have simple answers such as link library order, and the paths used - but I've already verified they're in place and working as expected.

`Linux 3.16.0-38-generic`
`gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3)` | I don't think you need a custom directive to fire the `$http` call to fetch the results whenever your input value changes.Instead you can do as below
```
<input type="text" ng-model="header.search"
typeahead-on-select="searchClicked($item)"
uib-typeahead="state as state.data.name for state in suggestions($viewValue) | filter:$viewValue | limitTo:8"
typeahead-min-length="0" placeholder="Søg..." >

In your JS controller you can write the function `$scope.suggestions()` to fetch the new results on query type.
```
var app = angular.module('plunker', ['ui.bootstrap']);
app.factory('dataProviderService', ['$http', function($http) {
var factory = {};
factory.getCities = function(input) {
//I've used google api to fetch cities ..we can place our service call here..
return $http.get('//maps.googleapis.com/maps/api/geocode/json', {
params: {
address: input,
sensor: false

return response.data.results.map(function(item) {
return item.formatted_address;

});
};
return factory;
}]);
app.controller('TypeaheadCtrl', ['$scope', '$log','$http', 'dataProviderService', function($scope, $log,$http, dataProviderService) {

286887 | I am making a search engine for songs using tags, and I have trouble building the SQL query that will list all the songs that match with the tags.
The database looks like this:
<http://i.imgur.com/5zmfAz8.png>
Songs have many Tags through an intermediate table(SongTags).
Let's have a population as example:
**Tags**:
Electro, Instrumental, Energetic, Melancholic, Vocal, Rock
**Songs**:
SongA (Electro, Melancholic, Vocal)
SongB (Instrumental, Melancholic, Rock)
SongC (Energetic, Vocal)
---
The search should return the songs that contains ALL the tags requested.
**Search1:**
"Vocal" returns: SongA, SongB
**Search2:**
"Vocal", "Energetic" returns: SongC
**Search3:**
"Vocal", "Energetic", "Electro" returns: nothing
---
I see how to do a search on 1 tag, but not on multiple tags.
For exemple for the Search1, I know that this would work:
```
SELECT * FROM "songs"
INNER JOIN "song_tags" ON "song_tags"."song_id" = "songs"."id"
INNER JOIN "tags" ON "tags"."id" = "song_tags"."tag_id"
WHERE "tags"."name" = 'Vocal'
```
But then I have no idea on how I could execute Search2, because I need the Song to contain both "Vocal" and "Energetic".
Edit:
I am using PostgreSQL | To understand why your code didn't work, you should understand what's `flashvars` parameter and how it's working.
Adobe said about that [here](https://helpx.adobe.com/flash/kb/pass-variables-swfs-flashvars.html), for example :
>
> The FlashVars parameter of the HTML <OBJECT> tag sends variables into the top level of a SWF file when it loads in a web browser. The <OBJECT> tag is used to add SWF files to HTML pages. The <EMBED> tag can also be used, but is older and now obsolete.
>
>
>
So here we can understand that those variables are loaded when the SWF is loaded and that's why even if you've changed the `flashvars` parameter, that will do nothing, absolutely nothing to that loaded SWF which should be loaded again to get them (variables) applied.
So to do that, take this simple example :
**HTML :**
```
<div id='swf_container'>
<embed id='swf_object' src='swf.swf' flashvars='id=1' />
</div>
```
**JavaScript :**
```
// change the flashvars attribute
var swf_object = document.getElementById('swf_object');
swf_object.setAttribute('flashvars', 'id=2');
var swf_container = document.getElementById('swf_container');
var inner_html = swf_container.innerHTML;
// reload the swf object
swf_container.innerHTML = '';
swf_container.innerHTML = inner_html;
```
This manner is, of course, working but maybe it's not a good idea to reload the SWF object everytime we need it to do something, and that's why we have [`ExternalInterface`](http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/external/ExternalInterface.html) to communicate between the SWF and JavaScript.
---
So in the case where you've access to the ActionScript code to create that SWF, you can use `ExternalInterface` to call any function in your SWF when it's already loaded.
For that, take this example :
**ActionScript :**
```
if(ExternalInterface.available)
{
// registers an AS function to be called from JS
ExternalInterface.addCallback('from_JS_to_AS', from_JS);
}
function from_JS(id:int) : void
{
// use the id sent by JS
}
```
**JavaScript :**
```
var swf_object = document.getElementById('swf_object');
swf_object.from_JS_to_AS(1234);
```
... and don't forget to use [`swfobject`](https://code.google.com/p/swfobject/) to avoid some browsers compatibility and to be sure that you establish the communication between your ActionScript side and the JavaScript one ...
Hope that can help. |
288351 | make\_shared allocates single block for object and reference counter. So there is an obvious performance benefit using such technique.
I made simple experiment in VS2012 and I was looking for 'evidence':
```
std::shared_ptr<Test> sp2 = std::make_shared<Test>();
std::shared_ptr<Test> sp(new Test());
// Test is a simple class with int 'm_value' member
```
when debugging I got in locals view something like this (some lines are deleted)
```
- sp2 shared_ptr {m_value=0 } [make_shared] std::shared_ptr<Test>
+ _Ptr 0x01208dec {m_value=0 } Test *
+ _Rep 0x01208de0 make_shared std::_Ref_count_base *
- sp shared_ptr {m_value=0 } [default] std::shared_ptr<Test>
+ _Ptr 0x01203c50 {m_value=0 } Test *
+ _Rep 0x01208d90 default std::_Ref_count_base *
```
It seems that **sp2** is allocated in **0x01208de0** (there is a ref counter) and then in **0x01208dec** there is an Test object. Locations are very close to each other.
In second version we have **0x01208d90** for ref counter, and **0x01203c50** for object. Those locations are quite distant.
Is this proper output? Do I understand this correctly? | If you read [cppreference's page for `make_shared`](http://en.cppreference.com/w/cpp/memory/shared_ptr/make_shared), they say:
>
> This function allocates memory for the `T` object and for the `shared_ptr`'s control block with a single memory allocation. In contrast, the declaration `std::shared_ptr<T> p(new T(Args...))` performs two memory allocations, which may incur unnecessary overhead.
>
>
>
So this is the intended behaviour and you interpreted it properly.
And of course, it makes sense; how could the `shared_ptr` control the allocation of an object you already allocated? With `make_shared`, you leave it in charge of allocating the object, so it can allocate space your object wherever it wants, which is right beside the counter.
*Addendum*: As Pete Becker noted in the comments, §20.7.2.2.6/6 of the Standard says that implementations are encouraged, but not required, to perform only one allocation. So this behaviour you observed should not be relied upon, though it's safe to say you have nothing to lose and something to gain if you always use `make_shared`. |

288568 | This may turn out to be a bit embarassing, but here it is. It is probably not true that the ascending and descending central series (\*) of a nilpotent group have the same terms. (Or at least one of MacLane-Birkhoff, Rotman and Jacobson would have mentioned it.) However, I have been unable to find an example where they are different. I thought I had a sketch of proof that they are always equal, but there is a gap, of the kind where you feel it is not patchable.
I've proved it for a few nilpotent groups (dihedral of the square, any group of order p^3, the Heisenberg groups of dimension 3 and 4 over any ring -- I think the argument extends to any dimension), and checked a few more exotic examples in the excellent [Group Properties Wiki](http://groupprops.subwiki.org/wiki/Main_Page).

(\*) For completeness, the ascending central series of a group G is defined by Z\_0 = 1, Z\_{i+1} = the pullback of Z(G/Z\_i(G)) along the projection, and the descending central series by G\_0 = G, G\_{i+1} = [G,G\_i]. The group G is nilpotent iff ever Z\_m = G or G\_m = 1. It turns out that if such m exists it is the same for both. | It's false even if $m=2$. Try the product of a group of order $2$ and a dihedral group of order $8$. The center has order $4$ and the quotient by the center is abelian. The commutator subgroup has order $2$. |
288594 | I want to fill an array with values. The **keys** of this array should be **readable dates** in the format 'YEAR-MONTH-DAY'. Starting point is '2010-5-25'.
The process should abort on the current date. Obviously, all dates should be valid dates.
I thought about doing this loop. But it seems that PHP is not able to check the condition of more than one in a 'for' loop. It does not give me any warnings or errors, though.
```
for ($d = 25, $m = 5, $y = 2010,
$this_day = date('j'),
$this_month = date('n'),
$this_year = date('Y');
($y <= $this_year) && ($m <= $this_month) && ($d <= $this_day);
$d++)
{
$values[$y.'-'.$m.'-'.$d] = 0; //fill array
$d++;
if(!checkdate($m, $d, $y)){
$d = 1;
$m++;
if($m > 12) { $m = 1; $y++; }
}
}
```
Doing this with nested loops would be rather painful.
One solution would be to use integer times as keys and then convert them later in another loop into the readable dates.
Is there a more efficient way? | Simply you can try using `strtotime()`. Example:
```
$values = array();
$oldDate = strtotime('2010-05-25');
while($oldDate <= time()){
$values[date('Y-m-d', $oldDate)] = 'Your value';
$oldDate += 86400;

289100 | I learned that numbers can be converted into strings with `sprintf`:
```
int main()
{
int n;
char s[32];
printf("n=");
scanf("%d",&n);
sprintf(s,"%d",n); //HERE
puts(s);
return 0;
}
```
Is it possible to convert a string into a number with a similar command, without checking if each character is a number? | Yes. You can use [`strtol`](http://linux.die.net/man/3/strtol) function.
```
long int strtol(const char * restrict nptr, char ** restrict endptr, int base);
```
The `strtol` convert the initial portion of the string pointed to by `nptr` to `long int` representation.
Better to not use `atoi`. It tells noting when unable to convert a string to integer unlike `strtol` which specify by using `endptr` that whether the conversion is successful or not. If no conversion could be performed, zero is returned.
Suggested reading: [correct usage of strtol](https://stackoverflow.com/a/14176593/2455888)
Example:
```
char *end;
char *str = "test";
long int result = strtol(str, &end, 10);
if (end == str || *temp != '\0')
printf("Could not convert '%s' to long and leftover string is: '%s'\n", str, end);

```
I tried using if statement based on what I find here. But it's not working, it just keeps on appending. | Everytime you call standardRoom function the `flag` variable is reset to 0, so it will always keeps adding the elements. Make sure you store that variable somewhere more global where you don't need to reset it:
```
var flag = 0;
function standardRoom() {
if ($('select#selectBoxStandard option').length > 1 ) {
flag++
$('#selectBoxStandard').find("option:nth-last-child(-n+" +
$('#selectBoxStandard').val() + ")").remove();
if (flag <= 1) {
$("#roomDetail ul").append('<li><strong>Standard Room - Regular Online Rate</strong> </li>').append('<li class="pull-right"><h4 style="color:darkorange">PHP {{$availableRooms[0]['nightRate']}}</h4></li>').append('<li>Number of night(s): {{$n_nights}} </li>').append('<li>Number of person(s): </li>').append('<li class="hr">Number of room(s): </li>').append(flag);
}
} else {
alert("No more rooms");

290484 | I want to use [jquery autocomplete](http://jqueryui.com/autocomplete/) jquery plugin, I test below code but nothing happend, I check, the file added correctly and there is not js error.

I had install `jquery update` module and set jquery version to 1.8 .
where is the problem?
**update**
after sometimes I type in textfield to test , I saw `TypeError: c.curCSS is not a function` in firebug, I search this error in google and suggestion in upgrade jquery ui to 1.9.3 but drupal not has version higher than 1.8. | Yes, jQuery UI is available in drupal core.
To include libraries like that you need to call the [drupal\_add\_library()](https://api.drupal.org/api/drupal/includes!common.inc/function/drupal_add_library/7) function to load the required js & css.
For exmaple:
```
drupal_add_library('system', 'drupal.autocomplete');
```
So where you are adding your javascript, add that first.
For example:
```
// Add the jQuery UI autocomplete library.
drupal_add_library('system', 'drupal.autocomplete');
// Load the custom js for this module.
drupal_add_js(drupal_get_path('module', 'MODULE_NAME') . '/js/SCRIPT_FILE.js');
```
The caps lock parts need to be changed to suit your module.
As for where you would put this, I can't say unless I know where you are putting your code. It could be in your theme or in a custom module.
If it is in your theme then the drupal\_add\_js() part would be drupal\_add\_js(drupal\_get\_path('theme', 'THEME\_NAME') . '/js/SCRIPT\_FILE.js');
I'm also assuming your scripts are in a js sub-directory.
You also need to make sure that any custom js you have is inside a drupal behavior (or $(document).ready() at the very least). Otherwise your javascript will run to early in the page load before the text field even is on the page, so it will do nothing.
It will be like this:
```
(function ($) {
Drupal.behaviors.yourThemeAutocomplete = {
attach: function (context, settings) {
// Your code goes here.
}
};
})(jQuery);
```

290790 | I'm learning to code in React from [Tyler Mcginnis' React course](https://tylermcginnis.com/courses/react/) (which I strongly recommend btw) and I decided to develop my own project, a university administration website, which can be displayed in different languages.
So far, I have developed the Login page, please **note that I'm using Babel**:
**Login.js**
```
import React from 'react'
import PropTypes from 'prop-types'
import { languagedata } from './Languages'
import languagesdata from '../languagesdata.json'
function LanguagesNav ({ selected, onUpdateLanguage}) {
const languages = ['EU', 'ES', 'EN']
return (
<div >
<h1 className='center-text header-lg'>
GAUR 2.0
</h1>
<ul className='flex-center'>
{languages.map((language) => (
<li key={language}>
<button
className='btn-clear nav-link'
style={language === selected ? { color: 'rgb(187, 46, 31)' } : null }
onClick={() => onUpdateLanguage(language)}>
{language}
</button>
</li>
))}
</ul>
</div>
)
}
LanguagesNav.propTypes = {
selected: PropTypes.string.isRequired,
onUpdateLanguage: PropTypes.func.isRequired
}
export default class Login extends React.Component {
constructor(props) {
super(props)
this.state = {
selectedLanguage: 'EU'
}
this.updateLanguage = this.updateLanguage.bind(this)
}
componentDidMount () {
this.updateLanguage(this.state.selectedLanguage)
}
updateLanguage (selectedLanguage) {
this.setState({
selectedLanguage
})
}
render() {
const { selectedLanguage } = this.state
return (
<React.Fragment>
<LanguagesNav
selected={selectedLanguage}
onUpdateLanguage={this.updateLanguage}
/>
<form className='column player'>
<label htmlFor='username' className='player-label'>
//Just testing whether JSON can be displayed
{ languagesdata.data }
</label>
<div className='row player-inputs'>
<input
type='text'
id='username'
className='input-light'
placeholder='Erabiltzailea'
autoComplete='off'
/>
</div>
<div className='row player-inputs'>
<input
type='password'
id='username'
className='input-light'
placeholder='Pasahitza'
autoComplete='off'
/>
</div>
<div className='row player-inputs'>
<button
className='btn dark-btn'
type='submit'
>
Sartu
</button>
</div>
</form>
</React.Fragment>
)
}
}
```
[](https://i.stack.imgur.com/C0zrY.png)
I would like to display the website in the selected language based on the information stored in a local JSON file:
```
[
{
"EU": {
"welcome": "Sartu GAUR 2.0ra",
"login": "Sartu"
},
"ES": {
"welcome": "Entra a GAUR 2.0",
"login": "Entrar"
},
"EN":{
"welcome": "Log into GAUR 2.0",
"login": "Log in"
}
}
]
```
I've tried several solutions that I've found on the Internet, but none of them worked for me.
I've tried importing a Javascript file that contains a JSON data (see below) and importing a JSON file itself (see JSON above).
```
const languagedata = {
"data": {
"languages": [
{
"euskara": {
welcome: "Sartu GAUR 2.0ra",
login: "Sartu"
},
"español": {
welcome: "Entra a GAUR 2.0",
login: "Entrar"
},
"english":{
welcome: "Log into GAUR 2.0",
login: "Log in"
}
}
]
}
};
```
Thus, I have 2 questions:
* What would be the best way to do what I'm trying to do?
* How can I display the JSON data in Login.js? | You can also get several documents by their id using:
```
Firestore.instance.collection('tournaments')..where(FieldPath.documentId, whereIn: myIdList).snapshots()
```
where myIdList is a List
