As you can see in the `$r` query, I am ordering by `exposure`. The exposure field can contain the numbers from `1-3`. What I am trying to do is to create a new row for each exposure number. Example:
Advertisements that have exposure = 1, will be in the first row
Below that, will be advertisements that have exposure = 2
And last, there will be advertisements that have exposure = 3
The way it is now, the advertisements/span4 divs are just being echoed out next to each other. I want to sort them inside the while loop in `<div class='row'></div>` | Why not try [jQuery post](http://api.jquery.com/jQuery.post/)?

157124 | See if i can get it working here: <https://codepen.io/canovice/pen/pVoBXJ>
I have searched a bit for this answer but have had no luck resolving the issue. Here is a screenshot of an anchor tag in a react component of mine:
[](https://i.stack.imgur.com/XToHn.png)
Notice the 3px margin (orange) and 3px padding (green), and also notice that below the text is a massive amount of white space that I would like to get rid of, but am struggling to do so. Any help is appreciated.
\*Note: I've tried the suggestions [at this link here](https://stackoverflow.com/questions/3197601/white-space-at-bottom-of-anchor-tag) with no luck...
\*Edit: let me know if theres more i can share on my app, ie. the current stylings, that will help.
**Javascript for the React component:**
```
import React from 'react';
import FaTwitter from 'react-icons/lib/fa/twitter';
import './TopPageHeader.css'
const TopPageHeader = () =>
<div className="top-page-container">
<a href="/">Canova's Analytics Dashboards</a>
<div className="social-links">
<a href="https://twitter.com/SmokeyCanova">
<FaTwitter />
</a>
</div>
</div>
export default TopPageHeader;
```
**and CSS:**
```
.top-page-container {
padding: 15px 20px;
margin: 0;
min-height: 30px;
height: auto;
width: 100%;
border-bottom: 1px solid #000;
display: flex;
justify-content: space-between;
}
.top-page-container a {
/*display: block;*/
/*height: auto;*/
vertical-align: bottom;
padding: 3px;
margin: 3px;
font-size: 1.75em;
/*padding: 15px 0px;*/
color: #000;
}
.top-page-container .social-links {
font-size: 1.75em;
/*padding: 15px 0px;*/
}
```
Lastly, here's what the component looks like on the top of my page. Canova Analytics Dashboard is not centered, but rather offcenter up a bit (due to this extra white space below the anchor tag)... Ideally, the vertical center of the text, and the vertical center of the twitter logo, would both be vertically centered on the div they are contained in.
[](https://i.stack.imgur.com/LWL9a.png)
Here's what the component is contained within...
This is a top page header component, and hence nothing before it. I don't think the css is being impacted anywhere else, but i could be wrong.

158499 | I'm currently getting troubled with the react router dom@6. Like, I want to redirect users to other pages If they logged in. But when I use Navigate component It threw error saying that :
"[Navigate] is not a component. All component children of Routes must be a Route or React.Fragment"
Though I have wrapped it in the fragment but the result still the same. Please help me, this is my code:
```
import {BrowserRouter as Router, Routes, Route, Navigate} from 'react-router-dom';
import Home from './pages/Home';
import ProductList from './pages/ProductList';
import Product from './pages/Product';
import Register from './pages/Register';

This is also a possible solution, drawback is that you cant redirect properly. You just have to make sure that you have the fallbackroutes set up right.
```
{isSignedIn && <Route path="" element={} />}

I would recommend using an AuthRout to wrap your Routes.
```js
function AuthRoute ({children}) {
if(!user.isSignedIn){
//Not signed in
return <Navigate to="/signIn" />
}
//Signed in
return children
}
//Route itself
<Route path="/abc" element={<AuthRoute><YourComponent /></AuthRoute>} />
```
That way the user gets redirected if he is not signed in |

I read that `$this->getImageLabel($_product, 'image_feature_front_right')` was the way to do it, but produces nothing. What am I doing wrong?
Thanks!
Tre | It seems you asked this same question in another thread, so to help others who might be searching for an answer, I'll anser it here as well:
I imagine this is some sort of magento bug. The issue seems to be that the Magento core is not setting the custom\_image\_label attribute. Whereas for the default built-in images [image, small\_image, thumbnail\_image] it does set these attributes - so you could do something like:
```
$_product->getData('small_image_label');
```
If you look at `Mage_Catalog_Block_Product_Abstract::getImageLabel()` it just appends '\_label' to the `$mediaAttributeCode` that you pass in as the 2nd param and calls `$_product->getData()`.
If you call `$_product->getData('media_gallery');` you'll see the custom image label is available. It's just nested in an array. So use this function:
```
function getImageLabel($_product, $key) {
$gallery = $_product->getData('media_gallery');
$file = $_product->getData($key);
if ($file && $gallery && array_key_exists('images', $gallery)) {
foreach ($gallery['images'] as $image) {
if ($image['file'] == $file)
return $image['label'];
}
}
return '';
}
```
It'd be prudent to extend the Magento core code (Ideally `Mage_Catalog_Block_Product_Abstract`, but I don't think Magento lets you override Abstract classes), but if you need a quick hack - just stick this function in your phtml file then call:
```
<?php echo getImageLabel($_product, 'image_feature_front_right')?>
``` |
159719 | Is there an equivalent to `getopt()` in the visual studio CRT?
Or do I need to get it and compile it with my project?
**Edit** clarification
`getopt` is a utility function in the unix/linux C Run Time library for common command line parsing chores i.e. parsing arguments of the form `-a -b` `-f someArg` etc' | Advice: boost::program\_options instead.

159784 | I have a normal list, and I want to change the element of that list every 25 indexes (starting by the second index). So I've created a loop to generate that number and store it in a list (i.e 2,27,52,77....). Then I've printed every item of that index, but for now I can't seem to find a way to work with re.sub.
I want to replace those elements by new ones, and then write all of items on the list (not just those I've changed) into a file.
**So the goal is using re.sub or some other method to replace:**
```
' Title =' by ' Author ='
```
How do I achieve this?
Here is my code:
```
counter = 0
length = len(flist) # Max.Size of List
ab = [2]
for item in flist:
counter +=1
a = ((25*counter)+2) #Increment
ab.append(a)
if a >= length:
ab.pop() #Removing last item
break
for i in ab:
print(flist[i-1]) #Printing element in that index
#replace item
#write to file
fo = open('somefile.txt', 'w')
for item in flist:
fo.write(item)
fo.close()
```
**PS: I'm new to python, sugestions and criticism is much apreciated!** | To match the text you can use:
```
new_str = re.sub(r'\s+Title\s+=', 'Author =', old_str)
```
`\s` means whitespace, `+` means one or more. You can use `\s{4}` to match exactly 4 whitespaces, or as many as you need. More info [here](https://docs.python.org/3/library/re.html).
Alternatively, you can use `replace()`:
```
new_str = old_str.replace(' Title =', 'Author =')
```
---
You can use `range()` to simplify the rest of your code a bit. range() has 3 arguments, 2 of which are optional; start, end, step.
```
for i in range(2, 200, 25):
print(i)
```
Finally, you can use `with open()` instead of `open()`:
```
with open('my_file.txt', 'w') as fo:
# Do stuff here.
....
....
# File closes automatically.

```

Thanks a lot for your help! | Java implements Generics using [Erasure](https://docs.oracle.com/javase/tutorial/java/generics/erasure.html). That means that at run-time, the JVM can't know what types are associated with the Generic class/method/object/whatever. There are hacks and workarounds that can be used to try to work with this, but this is a fundamental part of the language.
Given that you're working with JSON, you may wish to investigate whether the library has functions specialized for Generic datastructures. I happen to know for a fact that [GSON has functions specific to handling Generic data structures](https://google-gson.googlecode.com/svn/trunk/gson/docs/javadocs/com/google/gson/Gson.html#toJson(java.lang.Object,%20java.lang.reflect.Type)). |
160928 | Trying to restore an Amazon S3 object from GLACIER with the code below.
```
import boto3
s3 = boto3.resource('s3', verify=False)
bucket_name = r"my-source-bucket"
bucket = s3.Bucket(bucket_name)
key ="glacier_file2.txt"
try:
bucket.meta.client.restore_object(Bucket=bucket_name, Key=key, RestoreRequest={'Days': 1, 'GlacierJobParameters': {'Tier': 'Expedited'}})
except Exception as e:
print({"Problem Restoring": str(e)})
```
The code submits successfully, however the object still shows as in GLACIER in the AWS console as well as when I query it with boto3 even days later. If I run the following code I see it still shows GLACIER.
```
key = s3.Object(bucket_name,key)
print (key.storage_class)
print (key.restore)
>>>>GLACIER
>>>>ongoing-request="false", expiry-date="Sun, 19 Sep 2021 00:00:00 GMT"
```
When I try to do this same thing in the AWS console, I see that it says it's both in GLACIER AND restore is complete?
[](https://i.stack.imgur.com/wJZsI.png)
Does anyone have any insight? After restoring, I'm actually able to download the file, which tells me it's not actually in GLACIER, despite saying it is in the browser, and also in boto3. Is something wrong with how the storage class is being reported after a restore occurs?
**edit** I should point out I'm doing an expedited restore, which only takes a few minutes. | After doing a little more research, it appears that a "restore" is not what one would expect. Once an object goes to GLACIER there is no going back, other than "temporarily" restoring it (like I've done above) and then overwriting it. For example, I was able to run this command after restoring glacier\_file2.txt
```
aws s3 cp s3://my-source-bucket/glacier_file2.txt s3://my-source-bucket/glacier_file2.txt --force-glacier-transfer --storage-class STANDARD

161046 | ideally, I'd like to get the name of the property referenced by a KeyPath. But this seems not to be possible out-of-the-box in Swift.
So my thinking is that the KeyPath could provide this information based on protocol extension added by a developer. Then I'd like to design an API with an initializer/function that accepts a KeyPath conforming to that protocol (that adds a computed property).
So far I was only able to define the protocol and conditional conformance of the protocol. The following code compiles fine.
```
protocol KeyPathPropertyNameProviding {
var propertyName: String {get}
}
struct User {
var name: String
var age: Int
}
struct Person {
var name: String
var age: Int
}
extension KeyPath: KeyPathPropertyNameProviding where Root == Person {
var propertyName: String {
switch self {
case \Person.name: return "name"
case \Person.age: return "age"
default: return ""
}
}
}
struct PropertyWrapper<Model> {
var propertyName: String = ""
init<T>(property: KeyPath<Model, T>) {
if let property = property as? KeyPathPropertyNameProviding {
self.propertyName = property.propertyName
}
}
}
let userAge = \User.age as? KeyPathPropertyNameProviding
print(userAge?.propertyName) // "nil"
let personAge = \Person.age as? KeyPathPropertyNameProviding
print(personAge?.propertyName) // "age"
let wrapper = PropertyWrapper<Person>(property: \.age)
print(wrapper.propertyName) // "age"
```
But I am unable to restrict the API so that initialization parameter `property` has to be a KeyPath AND must conform to a certain protocol.
For example, the following would result in a compilation error but should work from my understanding (but probably I miss a key detail ;) )
```
struct PropertyWrapper<Model> {
var propertyName: String = ""
init<T>(property: KeyPath<Model, T> & KeyPathPropertyNameProviding) {
self.propertyName = property.propertyName // compilation error "Property 'propertyName' requires the types 'Model' and 'Person' be equivalent"
}
}
```
Any tips are highly appreciated! | You are misunderstanding conditional conformance. You seem to want to do this in the future:
```
extension KeyPath: KeyPathPropertyNameProviding where Root == Person {
var propertyName: String {
switch self {
case \Person.name: return "name"
case \Person.age: return "age"
default: return ""
}
}
}
extension KeyPath: KeyPathPropertyNameProviding where Root == User {
var propertyName: String {
...
}
}
extension KeyPath: KeyPathPropertyNameProviding where Root == AnotherType {
var propertyName: String {
...
}
}
```
But you can't. You are trying to specify multiple conditions to conform to the same protocol. See [here](https://stackoverflow.com/questions/57282655/why-there-cannot-be-more-than-one-conformance-even-with-different-conditional) for more info on why this is not in Swift.
Somehow, one part of the compiler thinks that the conformance to `KeyPathPropertyNameProviding` is not conditional, so `KeyPath<Model, T> & KeyPathPropertyNameProviding` is actually the same as `KeyPath<Model, T>`, because somehow `KeyPath<Model, T>` already "conforms" to `KeyPathPropertyNameProviding` as far as the compiler is concerned, it's just that the property `propertyName` will only be available *sometimes*.
If I rewrite the initialiser this way...
```
init<T, KeyPathType: KeyPath<Model, T> & KeyPathPropertyNameProviding>(property: KeyPathType) {
self.propertyName = property.propertyName
}
```

161452 | I'm using Rails 3 for the first time (especially asset pipelining and less-rails-bootstrap), so I might be missing some really basic concept here. I've tried two approaches for including the Twitter bootstrap CSS into my project and both have problems.
**Approach #1:** `app/assets/stylesheets/application.css` has `require twitter/bootstrap`. This includes the bootstrap css file using a separate link/href tag, which is good. However, the **problem** is that in my custom CSS file, say `app/stylesheets/mystyles.css` I am unable to access variables+mixins defined in less within the bootstrap code, like `@gray`, `.box-shadow`, etc.
**Approach #2:** Put `@import 'twitter/bootstrap'` at the top of `app/assets/stylesheets/mystyles.css`. This allows me to access variables+mixins defined in less (within the bootstrap code), which is good. However, the **problem** is that it pulls in the entire bootstrap CSS at the top of `mystyles.css` increasing the filesize. If there are a bunch of different stylesheets that `@import twitter/ bootstrap` it would cause a lot of duplication.
What's the recommended approach for handling this situation? | Your answer is sufficient if you want to exclusively use the default twitter bootstrap variables. If you find yourself wanting to override the variables and have them applied to BOTH twitter bootstrap's styles AND your own styles, you'll need to do separate out your variables into its own myvariables.less file and have that file included with twitter bootstrap instead of in the manifest.
Example
-------
application.css:
```
/*
* Notice we aren't including twitter/bootstrap/bootstrap in here
*= require bootstrap_and_overrides
*= require mystyles
*/
```
bootstrap\_and\_overrides.less:
```
# Bootstrap with both bootstrap's variables, and your own
@import "twitter/bootstrap/bootstrap";
@import "myvariables";
```
mystyles.less:
```
# Your styles with both bootstrap's variables, and your own
@import "myvariables";
h1 {
// Use
color: @textColor;
}
```
myvariables.less:
```
@import "twitter/bootstrap/variables";
@textColor: green;
``` |
161535 | I have a method which tests for the existence of a file prior to carrying out some manipulation of file content as follows:
```
Private Sub AddHeaderToLogFile()
''#Only if file does not exist
If Not File.Exists(_logPath) Then
Dim headerLogger As Logger
headerLogger = LogManager.GetLogger("HeaderLogger")
''#Use GlobalDiagnosticContext in 2.0, GDC in pre-2.0
NLog.GlobalDiagnosticsContext.Set("appName", _appName)
NLog.GlobalDiagnosticsContext.Set("fileVersion", _fileVersion)
NLog.GlobalDiagnosticsContext.Set("logId", 0)
headerLogger.Info("")
End If
End Sub
```
The idea is that if the file does not exist, then the file is generated by calls to the NLog logger instance, at which point the file is created and the specified header info is inserted. The method works fine from the application itself, however I have a simple NUnit test which implements a test method to verify that the file is created and populated as expected. When I step through with the debugger, I find that '\_logPath' is set to:
D:\Documents and Settings\TE602510\Local Settings\Temp\nunit20\ShadowCopyCache\4288\_634286300896838506\Tests\_-1937845265\assembly\dl3\7cdfe61a\aa18c98d\_f0a1cb01\logs\2010-12-22.log
Unfortunately, despite the fact that the file DOES exist, the call to File.Exists returns false. From earlier viewing of the config path the above path would appear to be correct for these NUnit tests. Does anybody have a clue what is happening here and what I need to do to get the desired result? The pathname to the log file as per the XP file system is:
D:\Documents and Settings\TE602510\My Documents\_VSSWorkArea\PsalertsIp\Tests\bin\Debug\logs

Paul J. | Short answer : of course it makes sense, you can apply a CPS-transform directly, you will only have lots of cruft because each argument will have, as you noticed, its own attached continuation
In your example, I will consider that there is a `+(x,y)` uncurried primitive, and that you're asking what is the translation of
```
let add x y = +(x,y)
```
(This `add` faithfully represent OCaml's `(+)` operator)
`add` is syntaxically equivalent to
```
let add = fun x -> (fun y -> +(x, y))
```
So you apply a CPS transform¹ and get
```
let add_cps = fun x kx -> kx (fun y ky -> ky +(x,y))
```
If you want a translated code that looks more like something you could have willingly written, you can devise a finer transformation that actually considers known-arity function as non-curried functions, and tream all parameters as a whole (as you have in non-curried languages, and as functional compilers already do for obvious performance reasons).
¹: I wrote "*a* CPS transform" because there is no "one true CPS translation". Different translations have been devised, producing more or less continuation-related garbage. The formal CPS translations are usually defined directly on lambda-calculus, so I suppose you're having a less formal, more hand-made CPS transform in mind.
The good properties of CPS (as a *style* that program respect, and not a specific transformation into this style) are that the order of evaluation is completely explicit, and that all calls are tail-calls. As long as you respect those, you're relatively free in what you can do. Handling curryfied functions specifically is thus perfectly fine.
Remark : Your `(cps-add k 1 2)` version can also be considered tail-recursive if you assume the compiler detect and optimize that cps-add actually always take 3 arguments, and don't build intermediate closures. That may seem far-fetched, but it's the exact same assumption we use when reasoning about tail-calls in non-CPS programs, in those languages. |

Another issue is that you forget to check the last sphere when printing the results.
Also, there is the issue that after reading the last line, `leer1.eof()` is still `false`. Only after trying to read past the end of the file will `eof()` be set. The correct way to read in the spheres is:

162047 | I have seen this effect on a few sites ( [CSS Wizardry](http://csswizardry.com/2012/02/pragmatic-practical-font-sizing-in-css/) - watch the logo/nav ) where an element stays in view while scrolling down the page (this is not the hard part) & then stops scrolling when it 'collides' (for want of a better word) with a specified element (the hard part).
I have found two plugins that aim to do just this but do not have all the functionality I need:
**1. jQuery lockScroll**
<http://www.anthonymclin.com/code/7-miscellaneous/108-jquery-lockscroll-13>
This forces the desired element to have position fixed to begin with, which could mean that if the element starts below the fold, it is never seen.
(Demo: <http://www.anthonymclin.com/media/demos/jquery.lockScroll.1.3/>)
**2. jQuery fixedScroll** Used on [CSS Wizardry](http://csswizardry.com/2012/02/pragmatic-practical-font-sizing-in-css/)
This forces position fixed again & it needs a top offset in order to work. This offset is applied on DOMReady & moves the element if it is not at that position - it is the offset used when scrolling.
Plugins that I am aware of that do not produce the desired effect:
* <https://github.com/dutchcelt/Keep-in-View>
* <http://imakewebthings.github.com/jquery-waypoints/sticky-elements/>

162386 | OK. I am facing some difficulties in understanding the basics of concurrency. This question is about Deadlock. Please tell me why are both of these threads end in a deadlock.
I took this example from [this](http://docs.oracle.com/javase/tutorial/essential/concurrency/deadlock.html) tutorial. And it says,
*"When Deadlock runs, it's extremely likely that both threads will block when they attempt to invoke bowBack. Neither block will ever end, because each thread is waiting for the other to exit bow."*
What I understand from this is that: First, they would wait because when a thread invokes a synchronized method, it automatically acquires the intrinsic lock of the object to which the synchronized method belongs, and continues to own it until the method returns; and meanwhile no other thread can own it.
**1. Now my first question is that the first thread calls zarah.bow(), so the intrinsic lock is associated with zarah. The second thread would call khan.bow() and so that would be a different intrinsic lock (because it is associated with a different object named khan), isn't it?**
**And aren't zarah.bow() and khan.bow() different? Because they belong to two different instances?**
**2. The second question is from the notion of "both" the threads waiting forever. Both the threads will be blocked forever waiting for each other to exit bow. I don't get this.**
```
package Threads;
public class DeadlockModified {
static class Friend {
private final String name;
Friend(String name){
this.name=name;
}
private String getName(){
return this.name;
}
private synchronized void bow(Friend bower){
System.out.format("%s: %s"+" bowed to me.%n",bower.getName(),name);
bower.bowBack(this);
}
private synchronized void bowBack(Friend bower){
System.out.format("%s: %s" + " was nice enough to bow back to me.%n",bower.getName() ,name );
}
}
public static void main(String [] args){
final Friend zarah= new Friend("Zarah");
final Friend khan= new Friend("Khan");
new Thread(new Runnable(){
public void run(){zarah.bow(khan);}
}).start();
new Thread(new Runnable() {
public void run(){khan.bow(zarah);}
}).start();
}
}
```
OUTPUT:-
```
Khan: Zarah bowed to me.
Zarah: Khan bowed to me.
```
Thank you in advance.
**Edit:-**
In this tutorial's section of "Synchronized methods" it was written that,
*"Invoking other objects' methods from synchronized code can create problems that are described in the section on Liveness."*
This is the section on Liveness. I see that another object's method bowBack() is being called from bow(). There are some problems as well- Looking at the output of the program, looks like bowBack() has not been executed by both the threads. But there aren't any more details given. | * Thread 1 calls `zarah.bow(khan)`: it acquires the intrinsic lock of the object referenced by `zarah`
* Thread 2 calls `khan.bow(zarah)`: it acquires the intrinsic lock of the object referenced by `khan`
* Thread 1 tries to call `khan.bowBack()`: it needs the intrinsic lock of khan to be able to do that. But this lock is held by Thread 2. So Thread 1 waits until thread 1 releases the lock of `khan`
* Thread 2 tries to call `zarah.bowBack()`: it needs the intrinsic lock of zarahto be able to do that. But this lock is held by Thread 1. So Thread 2 waits until thread 1 releases the lock of `zarah`
Both threads are thus waiting for each other, forever. That's a deadlock. |

163753 | I have been working on RAD Studio and on that this is performed automatically if the background is fully transparent, but it seems that it isn't as simple to do in Visual Studio. I have read articles and questions of functions GetWindowLong() and SetWindowLong(), but when I try to use them myself, I get error "the name xxx does not exist in the current context".
What I tried was:
```

{
public Form1()
{
InitializeComponent();
int initialStyle = GetWindowLong(this.Handle, -20);
SetWindowLong(this.Handle, -20, initialStyle | 0x80000 | 0x20);
}
}
}
```
So is there some file I have to include in order get it to work, or do I have to place the function elsewhere? I'm also curious to know why does it behave so differently in the RAD Studio and Visula Studio. | The methods you are using are not found in the standard .NET libraries, you need to invoke them through `user32.dll`.

{
if (IntPtr.Size == 4) return GetWindowLong32(hWnd, nIndex);
else return GetWindowLongPtr64(hWnd, nIndex);

Calling them this way will now work correctly:

**1)**
```
function restart(){ echo('restart') };
```
**2)**
```
function shutdown(){echo ('shutdown')};
```
then I include the **index.php** file to the **foo.php** and when I want to call index.php **methods** in an **eventHandler** in foo.php it doesn't work like this:
```
<?php
include ('index.php');
?>

console.log('restarted');
<?php
restart();
?>
})
</script>
</body>
</html>

output: **nothing and no errors**

and when I **remove** the php code **inside the eventHandler** it works! like this:
---
```

165052 | I'm hosting a Minecraft server that gets updated from time to time. I'd like to make it easy for players to know which mods they will need to play without requiring me to communicate with them outside of Minecraft.

Currently, if a player is missing a mod in their client, they will see a generic error message.
**Is there a way to inform users *in-game* which mods they will need?**
One idea I have is to put a web address on the game screen they see before joining, and then keep that web page updated, but that seems clunky.

165575 | I have a device ([NXQ1TXH5](https://eu.mouser.com/datasheet/2/302/NXQ1TXH5_SDS-1152191.pdf)) that I want to run at 5V. I am also interfacing this device with a Raspberry Pi4 for i2c communication. This raspberry pi 4 is going to be the master in my i2c network. This runs at 3v3.
As the title says, I want to pull up SDA/SCL to 3V3, as required by the datasheet (although the device can take up to 5v, the SDA/SCL only works with 3v3 (maximum 3.6V)).
**Datasheet mentioning 3v3**
[](https://i.stack.imgur.com/b1ZR7.png)
I could use a voltage regulator to step down from 5V to 3v3.t would require some filtering capacitor and more complex assembly
The second option is a voltage divider. Would a voltage divider do the trick here, given that the 5V source will be constant? (it's cheaper, although it might be less efficient)
If yes, what values? | The best option, when possible, especially in the case where there is a single I2C master, is to pull up to the same VCC as the I2C master. In your application that would be the Raspberry Pi VCC, I guess.
But it is still an interesting question. The basic answer is, yes, you can use a divider for pullup.
The effective pullup voltage is V \* R2 / (R1+R2) where R1 is the upper leg of the divider and R2 is the lower leg of the divider. The effective pullup resistance is R1 in parallel with R2, which is (R1\*R2)/(R1+R2).
[simulate this circuit](/plugins/schematics?image=http%3a%2f%2fi.stack.imgur.com%2fVYySX.png) – Schematic created using [CircuitLab](https://www.circuitlab.com/)
Note that the divider will consume power even when SDA and SCL are not pulled down. In micropower designs, the divider approach may not be the wisest option for that reason. An option (a bit odd, but potentially workable) would be to use a low quiescent current (Iq) linear regulator (possibly an LDO) to generate the 3.3V for the pullups. I have never seen this or had to resort to it, so I suspect it is not commonly needed. |

165949 | Trying to generate a random number and use it for variable value in Windows batch script file. Maybe I am missing something very basic, but something is not working here for me.
Created a batch file named `random_test.bat` with the following content.
```
SET rnumber=%random%
echo %random%
pause
```
Running the file consecutively three times produces the following set of outputs:
One
```
C:\Users\user\Desktop>SET rnumber=28955
C:\Users\user\Desktop>echo 20160
20160

C:\Users\user\Desktop>echo 18885
18885
C:\Users\user\Desktop>pause
Press any key to continue . . .
```
As you can see the command `echo %random%` keeps producing relatively random numbers between 0 and 32,767 as expected.
At the same time using `%random%` to set a value for variable `rnumber` does not. It produces a not-so random number (possibly too between 0 and 32,767) but it is not random. If I were to guess right now it seems to be slowly growing in the 0 to 32,767 direction.
To clarify the script keeps producing a random number with line 2 on each execution (20160, 13887, 18885...), but line 1 seems to produce a number that keeps increasing with each execution of the batch file (28955, 29072, 29183, and so on in my multiple tests).
I already tried it on two different computers, Windows 7 x64 and Windows 2012 R2 respectively, running this 3 line script multiple times in row.
Next thing to try will be on a computer from a completely different network, I'm wondering if this has anything to do with domain policies, network, software..
What is going on here?
UPDATE:
=======
When running the commands in sequence from the same CMD window it works as expected, but it does not when executing the same batch file multiple times.
* The line in the script `echo %random%` works as expected.
* The line `SET rnumber=%random%` does not.

srand((unsigned)time(NULL));
```
As a result when two(or more) CMD windows are started within the same second the initial returns of the %random% are the same. Subsequent returns of %random% within two CMD windows with the same seed and run time (to a second) are also the same.
Moreover if CMD windows are consequently started with certain delays from each other the first return of the %random% pseudo-variable in each new CMD window will be far from random and will be slowly increasing (0 to 32767 range). In my testing this initial seed number grows by either 3 or 4 every one second for each new window.

166204 | I've a strange issue. Let me explain in details below step by step:
1. I've a vendor developed REST WS (Made using WCF) for synchronizing data with MS CRM.
2. I've developed a windows service, which fetches batches of data to be synchronized from a database and then pass it to this web services using Post method as JSON objects. The windows service is deployed on one of the node.
3. The issue I am facing have never occurred in Dev, QA, UAT or staging environment. It's unique to Production environment only.
4. In production the application works for sometime and then starts throwing 400 Bad request error. Then until we restarts the site or reset the App Pool Identity the IIS keeps throwing 400 Bad request errors. When we restarts the site or App Pool then the same requests which were getting failed starts getting successful responses. It works for sometime like this and than again 400 starts happening.
5. The environment where web services are hosted is a Win Server 2012, 2 node load balanced environment. WS is deployed on port 8080 on boht nodes and configured to run under .Net 4.0.
6. I received the following error in my Windows Service log which is the client for these WS.
>
> System.Net.WebException: The remote server returned an error: (400)
> Bad Request.
> at SspToCrmSynchronizationService.Helpers.CrmWrapperWsHelper.CallService(String
> data, String url, String method, String userName, String password,
> String contentType) in CrmWrapperWsHelper.cs:line 79

> at SspToCrmSynchronizationService.Process.SequentialProcess.Process(List`1
> appList, DatabaseHelper dbHelperForChildTask, CancellationToken ct) in
> SequentialProcess.cs:line 88
>
>
>
6. First we've checked the IIS Logs and found that IIS is returning the 400 error in just few 100 MS. We suspect that it's not reaching to WS application since application is not logging any thing at all, despite that Logging the request is the first thing vendor is doing in the WS code.
7. Secondly we used Fiddler to capture the request and response and get the following:
>
>
> ```
> HTTP/1.1 400 Bad Request
> Cache-Control: private
> Content-Length: 1647
> Content-Type: text/html
> Server: Microsoft-IIS/8.5
> X-ASpNet-Version: 4.0.30319

> Date: Tue, 17 Oct 2017 07:14:26 GMT
>
> ```
>

8. Than we checked the IIS Httperr.log. In the log we found the following for some of the request and not for every failed requests. It seems nothing is there.
>
> 2017-07-07 03:32:45 10.102.2.52 63726 10.102.2.52 8080 - - - - - Timer\_ConnectionIdle -

9. Than we configured the Failed Traced Log in IIS for 400 and got one warning in the trace log when this 400 Error is thrown. I've erased some of the data from the image due to NDA and security reasons.
[](https://i.stack.imgur.com/VHHxs.png)
Basically the Warning details are as follows:
>
>
> ```
> 124. MODULE_SET_RESPONSE_ERROR_STATUS
> ModuleName="ManagedPipelineHandler",
> Notification="EXECUTE_REQUEST_HANDLER",
> HttpStatus="400",
> HttpReason="Bad Request",
> HttpSubStatus="0",
> ErrorCode="The operation completed successfully. (0x0)",
> ConfigExceptionInfo=""
>
> ```
>
>
10. After that I've compared one error case and one success case. Below is the image. What I noticed is that in case of failure General\_Read\_Entity\_Start and General\_Read\_Entity\_End didn't occurred at all.
[](https://i.stack.imgur.com/O382L.png)
The maximum I can understand is that somehow IIS is not able to parse JSON String to some Entity and the AppPool gets crashes then starts throwing 400 errors until a AppPool or IIS Reset is not done. I've no idea what is causing this (Root Cause) and how to resolve this and why it's working initially and not working after some time. Any help would be highly appreciated.
**[Edits]**
1. Resource consumption on the server is less then 10%.
2. For successful cases the average response time of WS are 5 secs, while for Error cases it returns within 100 Milli Seconds.
3. We did the Stress test for the service in test for about 100+ request and all went ok. | We need to understand how it works, there were quite a few conditions:
1. We were passing a datetime value in JSON. At the WS end the DateTime value was throwing some parsing errors when The WS container in our case (IIS and WCF) trying to pass the DateTime field to the application was failing in doing the conversion. I believe this could be due to locale. We fixed it by changing datetime to string in the WS accepted JSON.
2. The second issue was that our vendor used WCF as a technology to create RestAPI. One behavior of WCF is that if a request from a client causes a fatal exception to occour in the WS container the IIS will register this client on a block list and will not forward the request from the same client to the application until an IIS restart is done. The IIS will keep returning us Bad Request status message. |

So. `p.terminate()` kills the process you created, but the OS process (`/bin/bash ./test.sh`) simply gets assigned to the system's scheduler process and continues executing.
You could use [subprocess.Popen](https://docs.python.org/2/library/subprocess.html#popen-constructor) instead:

169111 | The problem:
============
I have several Rmarkdown documents representing different sections of my thesis (e.g. chapter 1 results, chapter 2 results), and I would like to combine the knitted latex versions of these documents with other TeX files into a master TeX 'thesis' document. The problem is, that when knitting to PDF and keeping the TeX file to include in the master TeX document, Rstudio auto-generates a bunch of preamble that ends up clashing with my preamble in the master.TeX document.
A less than ideal, workaround:
==============================
I have been working around this issue by deleting this preamble by hand before including the knitted output into the `master.tex` file.
So far my current workflow is as follows:
* set the output to pdf\_document in the YAML header, with the keep\_tex option set to true.
* knitPDF using the Rstudio button
* delete the preamble at the beginning of the knitted TeX files by hand.
* include the files into my master.tex file using \include{}
The question:
=============
I would like to convert Rmd to LaTeX, without having to delete the preamble manually before including the knitted TeX files into a master TeX file. How do I do this?
### Sweave is not an option:
I'm sure I could achieve this by working with Sweave, however I like the flexibility of output formats that Rmarkdown offers: I can knit to html and view in my browser as I'm writing, to quickly view the progress of my work and ensure that there are no bugs, and I can also choose to knit to word to share with my supervisor who works only in word. Then, when I'm ready to compile everything into my master LaTeX document for printing, I can select knit to PDF in Rstudio to obtain the latex output. | Here is a simpler solution using the LaTeX package `docmute`.
Your main Rmarkdown document, (e.g., `main.Rmd`) should load the `docmute` package and include your other files (e.g., `part1.Rmd` and `part.Rmd`), once knitted and located in the same directory, with `\input` or `\include`like this:
```
---
title: "Main"
output: pdf_document
header-includes:
- \usepackage{docmute}
---
# Part 1
\input{part1.tex}
# Part 2
\input{part1.tex}
```
Then your other files just need to have a `keep_tex` argument in the YAML front matter. Like this:
```
---
title: "Part 1"
output:
pdf_document:
keep_tex: true
---
Something
```
and this:
```
---
title: "Part 2"
output:
pdf_document:
keep_tex: true
---
Something else
```
Then all you need to do is knit `part*.Rmd`'s before `main.Rmd` and all the content will appear in `main.tex` and `main.pdf`. The `docmute` package strips the preamble from the input `.tex` files so you will need to make sure anything you need before `\begin{docunent}` in the input files is also in `main.Rmd`. |

To persist any data you are going to have to use an external resource. You can write to an actual file in any path in the file system. That file is going to be external to your class path files. |

170020 | I am writing a batch file that executes a Powershell script that at one point loops items with UNC paths as attributes and uses `Get-ChildItem` on those paths. In a minimal version, this is what is happening in my scripts:
**Master.bat**
```
powershell -ExecutionPolicy ByPass -File "Slave.ps1"
```
**Slave.ps1**
```
$foo = @{Name = "Foo"}
$foo.Path = "\\remote-server\foothing"
$bar = @{Name = "Bar"}
$bar.Path = "\\remote-server\barthing"
@( $foo, $bar ) | ForEach-Object {
$item = Get-ChildItem $_.Path
# Do things with item
}
```
The problem I'm running into is that when I run **Master.bat**, it fails at `Get-ChildItem` with an error along the lines of
```
get-childitem : Cannot find path '\\remote-server\foothing' because it does not exist.
```
However, it seems to work perfectly fine if I run the **Slave.ps1** file directly using Powershell. Why might this be happening only when the **Master.bat** file is run?
**Things I have tried**
* Prepending the UNC paths with `FileSystem::` with providers <http://powershell.org/wp/2014/02/20/powershell-gotcha-unc-paths-and-providers/>
* Making sure there are no strange characters in the actual paths
* Using the `-literalPath` parameter instead of the plain `-path` parameter for `Get-ChildItem`
* Running `Get-ChildItem \\remote-server\foothing` in PowerShell and succeeding to verify connection to the remote server | I have found this issue when running scripts referring to UNC paths - but the error only occurs when the root of the script is set to a non file system location. e.g. PS SQLSEVER\
So the following fails with the same error:
```
cd env:
$foo = @{Name = "Foo"}
$foo.Path = "\\remote-server\foothing"
$bar = @{Name = "Bar"}
$bar.Path = "\\remote-server\barthing"
@( $foo, $bar ) | ForEach-Object {
$item = Get-ChildItem $_.Path
# Do things with item
Write-Host $item
}
```
So my resolution was to ensure that the PS prompt was returned to a file system location before executing this code. e.g.
```
cd env:
$foo = @{Name = "Foo"}
$foo.Path = "\\remote-server\foothing"
$bar = @{Name = "Bar"}
$bar.Path = "\\remote-server\barthing"
cd c: #THIS IS THE CRITICAL LINE
@( $foo, $bar ) | ForEach-Object {
$item = Get-ChildItem $_.Path
# Do things with item
Write-Host $item
}
```
I hope this helps - I would be very happy with the bounty as this is my first answer on stack overflow.
P.S. I forgot to add - the PS command prompt root may be set by auto loaded modules in the configuration of your machine. I would check with Get-Location to see if you are actually executng from a non FileSystem location. |

170374 | DX12 introduces a new feature of pipeline named 'Bundle'. It seems that can optimize the command list, and send it to final pipeline. Vulkan invent some different pipeline: The graphic pipeline and the compute pipeline. The graphic pipeline seems just the same with the original, the compute pipeline is used as an accessor of image memory.
My CG knowledge is pretty basic, and can not confirm that cognition is correct. Would someone kindly provide some explanations for it - The main difference of pipelines between them ?
References:
* <https://msdn.microsoft.com/zh-cn/library/mt617309>
* <https://www.khronos.org/registry/vulkan/specs/1.0/xhtml/vkspec.html#pipelines> | D3D12 has 4 separate kinds of command lists: direct, bundle, compute, and copy.
Vulkan has similar concepts, but they happen in a different way. Command buffers are allocated from command pools. And command pools are directly associated with a queue family. And command buffers allocated from a pool can only be submitted to the queue family for which the pool was built.
Queue families specify the kinds of operations that the queue can take: graphics, compute, or memory copying operations. D3D12's command queues have a similar concept, but D3D12's command list API has you to specify the list type. Vulkan's gets this information from the queue family the pool is meant for.
The D3D12 "bundle" command list type seems similar on the surface to Vulkan secondary command buffers. However, they are quite different.
The principle difference is this: bundles inherit *all state* from their executing direct command list, except for the bound PSO itself. This includes resource descriptor bindings.
Vulkan secondary command buffers inherit *no state* from their primary command buffer execution environment, except for secondary CBs that execute in a subpass of a renderpass instance (and queries). And those *only* inherit the current subpass state (and queries).
This means you do different things with them, compared to D3D bundles.
Bundles are sometimes used to modify descriptor tables and render stuff, on the assumption that the direct command list they're executed within will have set those tables up. So bundles are kind of like light-weight OpenGL display lists, only without all of the bad things those do. So the intent with bundles is that you build them once and keep them around. They're supposed to be small things.
Vulkan secondary CBs are essential for threaded building of commands intended for a single render pass instance. This is because a render pass instance can only be created within a primary CB, so for optimal use of threads, there needs to be a way to create commands meant to execute in the same subpass in different threads. That's one of the main use-cases of secondary CBs. So the intent is that you'll probably build secondary CBs each frame (though you can reuse them if you want).
So in the end, bundles and secondary CBs are intended to solve separate problems. Bundles are generally dependent on the executing environment, while secondary CBs are more stand-alone.
At the same time, Vulkan secondary CBs can do something bundles cannot: they can execute on compute/copy-only queues. Since Vulkan makes a distinction between the primary/secondary level of the command buffer and the queues where that CB can be sent, it is possible in Vulkan to have secondary command buffers that execute on compute or copy-only queues.
Direct3D 12 can't do that with bundles. The [`ExecuteBundle` function](https://msdn.microsoft.com/en-us/library/windows/desktop/dn903882(v=vs.85).aspx) can only be called on a direct command list. So a copy-only command list cannot execute bundles.
Granted, because Vulkan doesn't inherit anything between secondary CBs except for subpass state, and compute/copy operations don't use render passes, there isn't much to be gained from putting such commands in a secondary CB rather than a primary one.
---
D3D12 has the same separation between [compute pipelines](https://msdn.microsoft.com/en-us/library/windows/desktop/dn788663(v=vs.85).aspx) and [graphics pipelines](https://msdn.microsoft.com/en-us/library/windows/desktop/dn770348(v=vs.85).aspx) that Vulkan does. However, when issuing commands, D3D12 has only one pipeline binding point, to which you can bind any kind of pipeline. By contrast, Vulkan has separate binding points for compute and graphics pipelines. Of course, Vulkan doesn't have different descriptor binding points for them, so the two pipelines can interfere with one another. But if you design their resource usage carefully, it is possible to invoke a dispatch operation without disturbing the needs of the graphics pipeline.
So overall, there's no real difference in pipeline architecture here. |
171102 | I have a problem with renderUI and I couldn't find a solution anywhere. Probably I'm asking the wrong question to google and more than a shiny problem is a basic R problem.

Error: argument 1 (type 'list') cannot be handled by 'cat'
```
and
```
Error:no applicable method for 'xtable' applied to an object of class "character"

**i dont know what this serialize do in this class can someone help me out** | This `serialize` method is just translating the model into other format for interoperability. In your case it's translating `Email` object into `dictionary` format.
This method is not built-in it's custom method, you can use custom method based on your use case.
Moreover, the name `serialize` is not also fixed, like `self` you can use any name as you like. `django` has also it's own `serializer` check here to know about `django serializers` <https://docs.djangoproject.com/en/3.0/topics/serialization/> |
172971 | I have two VMs (in VirtualBox), both of them are Ubuntu Server 18.10 (cosmic):
* the first one, `Server`, has two NICs: one in NAT, the other one in intnet
* the second machine, `Client`, has only one NIC, in intnet, to communicate with `Server`
Now I would like to make `Server` a gateway, and so I've enabled IP forwarding (by modifying `sysctl.conf`, restarted it and so on.
When I check `sudo ufw status` (on `Server`), it says `inactive`. OK. But I cannot ping any external IP address on `Client` until I set iptables on `Server` with
>
> `iptables -t nat -A POSTROUTING -o enp0s3 -j MASQUERADE`
>
>
>
As soon as I press Enter, ping command typed in `Client` does work. But why, since UFW is inactive?? | UFW being inactive has nothing to do with it.
In `iptables` parlance, you *must* have a `MASQUERADE` rule set in the NAT table for traffic to work being forwarded outbound regardless. Otherwise, the system won't know what to do with the packets. This remains the case even if you directly use `iptables` to manipulate the `*filter` rules (to set `INPUT`, `OUTPUT`, etc. access control lists and such, or even to just `ALLOW` all traffic on those policysets) - NAT always is in play and you have to add the NAT rule to make forwarded traffic masquerade out to the Internet as the server's primary IP.
Therefore, you must add the rule whether using UFW or not in order to get the system to understand how to translate the packet and route it via the server to the Internet, and thus how to automatically handle the reverse routing as well.
---
[This Github GIST](https://gist.github.com/kimus/9315140#nat) which I found has a pretty good explanation of what to do for this for UFW:
>
> The final step is to add NAT to ufw’s configuration. Add the following

173039 | I am just a beginner with angularJs , and i am trying to do CRUD Operations using $http and asp.net MVC :-
1. I am using ng-repeat to display list of "Terms" .
2. I have a
button to display a dialog ,which in turn will be used to inserting
new "Term".
3. ng-repeat works well and the dialog also displayed
and i can insert new item successfully.
the problem is :-
- after inserting new term and closing the dialog , ng-repeat doesn't updating . and this the code i am using :
```
var glossayApp = angular.module("glossaryApp", ['ui.bootstrap.dialog']);
var ctrl = glossayApp.controller("termController", function ($scope, $http, $route, $dialog, $window) {
$scope.terms = [];
$scope.init = function () {
$http.get("/Home/List").success(function (data) {
$scope.terms = data;
});
}
$scope.add = function () {
$scope.opts = { backdrop: true, keyboard: true, backdropClick: true, templateUrl: '/Home/Add', controller: 'dialogController' };
var d = $dialog.dialog($scope.opts);
d.open().then(function (term) {
if (term) {
$http.post('/Home/Add/', { Name: term.name, Definition: term.definition }).success(function () {
$scope.init();
});
}
});
}
});
glossayApp.config(function ($routeProvider) {
$routeProvider.when('/', {
controller: 'termController', templateUrl: '/Home/list'
}).when('/Details:id', {
controller: 'termController', templateUrl: '/Home/details'
}).otherwise({
redirectTo: '/'
});
});
var dialogController = glossayApp.controller('dialogController', function ($scope, dialog) {
$scope.save = function (term) {
dialog.close(term);
}
$scope.close = function () {
dialog.close();
}
});
```
and this the HTML I am using in ngrepeat :-
```
<table border="0" cellpadding="0" cellspacing="0" ng-init="init();">
<thead>
<tr>
<td>
Term
</td>
<td>
Definition
</td>
</tr>
</thead>
<tr ng-repeat="term in terms">
<td>
{{term.Name}}
</td>
<td>
{{term.Definition}}
</td>
</tr>
</table>
<br />
<input type="button" name="Add" value="Add New Term" ng-click="add();" />
``` | at the first glance , I guessed that the problem is the Scope , so I worked around it , I attached a CSS class to the table element which contains ng-repeat directive , this is my working code :
```
$scope.add = function () {
$scope.opts = { backdrop: true, keyboard: true, backdropClick: true, templateUrl: '/Home/Add', controller: 'dialogController' };
var d = $dialog.dialog($scope.opts);
d.open().then(function (term) {
if (term) {
$http.post('/Home/Add/', { Name: term.name, Definition: term.definition }).success(function () {
$http.get("/Home/GetData").success(function (data) {
var termscope = angular.element($(".term")).scope();
termscope.terms = data;
termscope.$apply();
});
});
}
});
}
```
I get the scope of the table which contains ng-repeat using :-
```
var termscope = angular.element($(".term")).scope();
```
and set terms variable again :-
```
termscope.terms = data;
```
and at the end i need to call $apply to update view(html).
```
termscope.$apply();
```
and it works well and updated the ng-repeat (view) after closing the dialog with no problem . |

public String Fragment { get { return Input.Substring(startFragment, (endFragment - startFragment)); } }

Match match = Regex.Match(s, pattern, RegexOptions.Singleline);
if (match.Success)
{
try
{
html.Input = s;
html.Version = Double.Parse(match.Groups["version"].Value, CultureInfo.InvariantCulture);
html.Source = match.Groups["source"].Value;
html.startHTML = int.Parse(match.Groups["startH"].Value);
html.endHTML = int.Parse(match.Groups["endH"].Value);
html.startFragment = int.Parse(match.Groups["startF"].Value);
html.endFragment = int.Parse(match.Groups["endF"].Value);

catch (Exception fe)

175142 | I am confused by the behavior of `is.na()` in a for loop in R.
I am trying to make a function that will create a sequence of numbers, do something to a matrix, summarize the resulting matrix based on the sequence of numbers, then modify the sequence of numbers based on the summary and repeat. I made a simple version of my function because I think it still gets at my problem.
```
library(plyr)
test <- function(desired.iterations, max.iterations)
{
rich.seq <- 4:34 ##make a sequence of numbers
details.table <- matrix(nrow=length(rich.seq), ncol=1, dimnames=list(rich.seq))
##generate a table where the row names are those numbers
print(details.table) ##that's what it looks like
temp.results <- matrix(nrow=10, ncol=2, dimnames=list(1:10))
##generate some sample data to summarize and fill into details.table
temp.results[,1] <- rep(5:6, 5)
temp.results[,2] <- rnorm(10)
print(temp.results) ##that's what it looks like
details.table[,1][row.names(details.table) %in% count(temp.results[,1])$x] <-
count(temp.results[,1])$freq
##summarize, subset to the appropriate rows in details.table, and fill in the summary
print(details.table)
for (i in 1:max.iterations)
{
rich.seq <- rich.seq[details.table < desired.iterations | is.na(details.table)]
## the idea would be to keep cutting this sequence of numbers down with
## successive iterations until the desired number of iterations per row in
## details.table was reached. in other words, in the real code i'd do
## something to details.table in the next line
print(rich.seq)
}
}
##call the function
test(desired.iterations=4, max.iterations=2)
```
On the first run through the for loop the rich.seq looks like I'd expect it to, where 5 & 6 are no longer in the sequence because both ended up with more than 4 iterations. However, on the second run, it spits out something unexpected.
UPDATE
Thanks for your help and also my apologies. After re-reading my original post it is not only less than clear, but I hadn't realized count was part of the plyr package, which I call in my full function but wasn't calling here. I'll try and explain better.
What I have working at the moment is a function that takes a matrix, randomizes it (in any of a number of different ways), then calculates some statistics on it. These stats are temporarily stored in a table--temp.results--where temp.results[,1] is the sum of the non zero elements in each column, and temp.results[,2] is a different summary statistic for that column. I save these results to a csv file (and append them to the same file at subsequent iterations), because looping through it and rbinding hogs a lot of memory.
The problem is that certain column sums (temp.results[,1]) are sampled very infrequently. In order to sample those sufficiently requires many many iterations, and the resulting .csv files would stretch into the hundreds of gigabytes.
What I want to do is create and then update a table (details.table) at each iteration that keeps track of how many times each column sum actually got sampled. When a given element in the table reaches the desired.iterations, I want it to be excluded from the vector rich.seq, so that only columns that haven't received the desired.iterations are actually saved to the csv file. The max.iterations argument will be used in a break() statement in case things are taking too long.
So, what I was expecting in the example case is the exact same line for rich.seq for both iterations, since I didn't actually do anything to change it. I believe that flodel is definitely right that my problem lies in comparing a matrix (details.table) of length longer than rich.seq, leading to unexpected results. However, I don't want the dimensions of details.table to change. Perhaps I can solve the problem implementing %in% somehow when I redefine rich.seq in the for loop? | Your `break`s are breaking out of the `switch ... case` not the `while`. You'll need to use some kind of boolean flag to break out of the outer loop, e.g.:
```
bool someflag = true;
while(someflag){
switch(something){
case a:
someflag = false; // set the flag so we break out of the loop
break; // break out of the switch-case so we don't enter case b
case b:
// do something else
break;
}
}
```
`-------- EDIT, because I misunderstood the question ------------`
I think you need an extra state in your logic, right now (ignoring state 1), you have two states:
1. Wait for a `p`, when you get one, goto 2.
2. `printf` for each character until you get an `r`, then goto 1
What you want is:
1. Wait for a `p`, when you get one, goto 2.
2. Do a `printf`, then goto 3.
3. Wait for an `r`, when you get one, goto 1. |

175599 | I am importing via RSS various news articles from various sources (all beyond my coding/formatting control) into my client's database (all legal!) and I am attempting to standardize some of their styling for presentation on client's site via jQuery. For example...
Many many sites use various header tags seemingly for formatting only. When these are pulled into client's presentation they look like crap, so I have working code to find and replace these code blocks with a styled paragraph (the semantics of this code are not important, we mainly link back to original source), and it works fine. Code:
```
$(document).ready(function() {
$('#selector h1, #selector h2:not(.article_name), #selector h3, #selector h4, #selector h5').replaceWith(function() {
return '<p class="h_replace">' + $(this).text() + '</p>';
});
});
```
The `.h_replace` CSS simply enlarges the `<p>` and adds some other attributes to make it more heading-like. So far, so good.
But here's where I'm hitting a wall: same sites also often use a `<p>` immediately followed with a child `<b>` *as the only content* to substitute/act as a `heading`.
I want to find and replace these code blocks with a styled paragraph (as above), but I am **unsuccessful** selecting any `<p>` that contains **ONLY** a `<b>` element. That is to say I want to select this:
```
<p><b>Some content here.</b></p>
```
and not this:
```
<p><b>Some Bold Text:</b> and some NOT bold text.</p>
```
In the first example, the `<p>` contains ONLY a child `<b>` element. In the second example the `<p>` contains a child `<b>` element as well as paragraph text not enclosed in the child `<b>`.
I am looking to programmatically select only the first type of `<p>`, and not the second.
Any ideas?
Here's what I've got so far, but it selects both instances:
```
$(document).ready(function() {
$('#selector p b:only-child').parent('p').replaceWith(function() {
return '<p class="h_replace">' + $(this).text() + '</p>';
});
});
```
The `:only-child` selector I thought would be a magic bullet, but then, of course, the `<b>` **IS** the only child of the `<p>` in both cases.
I need to select paragraphs that contain *only* and *nothing but* `<b>` content.
I hope that's clear.
As always, any help is always greatly appreciated. | Try this:
```
var els = $('p').filter(function() {
return /^<(b)>.+<\/\1>$/.test($.trim($(this).html()));
});
```
It will get you all `p` that have an only children `b` without any text nodes. You can change `(b)` with whatever tag in the code above.
**Edit:** Don't know why the downvote but this works just fine:
* `<p><b>Something</b></p> // true`
* `<p> <b>Something</b> </p> // true`
* `<p><b>Something</b> lorem</p> // false`
* `<p>lorem <b>Something</b></p> // false`
* `<p><span><b>Something</b></span></p> // false`

If you need to reset the state on click on other div you can just add $(".block-in-div").removeClass('not-resized'); at the end.

176816 | I am trying to read a single file from a `java.util.zip.ZipInputStream`, and copy it into a `java.io.ByteArrayOutputStream` (so that I can then create a `java.io.ByteArrayInputStream` and hand that to a 3rd party library that will end up closing the stream, and I don't want my `ZipInputStream` getting closed).
I'm probably missing something basic here, but I never enter the while loop here:
```
ByteArrayOutputStream streamBuilder = new ByteArrayOutputStream();
int bytesRead;
byte[] tempBuffer = new byte[8192*2];
try {
while ((bytesRead = zipStream.read(tempBuffer)) != -1) {
streamBuilder.write(tempBuffer, 0, bytesRead);
}
} catch (IOException e) {
// ...
}
```
What am I missing that will allow me to copy the stream?
**Edit:**
I should have mentioned earlier that this `ZipInputStream` is not coming from a file, so I don't think I can use a `ZipFile`. It is coming from a file uploaded through a servlet.
Also, I have already called `getNextEntry()` on the `ZipInputStream` before getting to this snippet of code. If I don't try copying the file into another `InputStream` (via the `OutputStream` mentioned above), and just pass the `ZipInputStream` to my 3rd party library, the library closes the stream, and I can't do anything more, like dealing with the remaining files in the stream. | Your loop looks valid - what does the following code (just on it's own) return?
```
zipStream.read(tempBuffer)
```
if it's returning -1, then the zipStream is closed before you get it, and all bets are off. It's time to use your debugger and make sure what's being passed to you is actually valid.
When you call getNextEntry(), does it return a value, and is the data in the entry meaningful (i.e. does getCompressedSize() return a valid value)? IF you are just reading a Zip file that doesn't have read-ahead zip entries embedded, then ZipInputStream isn't going to work for you.
Some useful tidbits about the Zip format:
Each file embedded in a zip file has a header. This header can contain useful information (such as the compressed length of the stream, it's offset in the file, CRC) - or it can contain some magic values that basically say 'The information isn't in the stream header, you have to check the Zip post-amble'.
Each zip file then has a table that is attached to the end of the file that contains all of the zip entries, along with the real data. The table at the end is mandatory, and the values in it must be correct. In contrast, the values embedded in the stream do not have to be provided.
If you use ZipFile, it reads the table at the end of the zip. If you use ZipInputStream, I suspect that getNextEntry() attempts to use the entries embedded in the stream. If those values aren't specified, then ZipInputStream has no idea how long the stream might be. The inflate algorithm is self terminating (you actually don't need to know the uncompressed length of the output stream in order to fully recover the output), but it's possible that the Java version of this reader doesn't handle this situation very well.
I will say that it's fairly unusual to have a servlet returning a ZipInputStream (it's much more common to receive an inflatorInputStream if you are going to be receiving compressed content. |

Can someone tell me what causes this?
Many thanks | As @nico\_ekito says, your import is incorrect, and should be `org.junit.Test`.
But this doesn't explain your problem:
```
[WARNING]..... error: object junit is not a member of package org
[WARNING] import org.junit.framework.Test
[WARNING] ^
```
So it can't find org.junit. This means that org.junit isn't in the classpath when you're compiling the tests. So either your dependency tree is screwed up, or the actual jar is.
Try
```
mvn dependency:list
```
This should result in something like:
```
[INFO] The following files have been resolved:
[INFO] junit:junit:jar:4.8.1:test
```
Ensure that you've got no other junit libraries being resolved. If everything looks ok, check the contents of your junit jar. It should contain the class org.junit.Test. If it doesn't, you've got a corrupted repo, or you're not looking in the right place. The easiest way to know this is to use:
```
mvn dependency:copy-dependencies
```
which creates target/dependency with a copy of the dependencies. You can look at the jar there. |

178417 | I am confused by the Bundle/Gem approach of global dependencies. I thought global dependencies are a thing of a past. I present to you two approaches of handling dependencies, NPM vs Bundle/Gem.
### NPM
Let me demonstrate the power of NPM. Say you have an app with the following folder structure:
```
/app
/admin
package.json
/front-end
package.json
```
You can see that inside my app I have two other mini-apps. Each of those has its own `package.json`.
Say both of them have `q` as a requirement, but with **different version**. Running `npm install` in both of these folders will install appropriate versions to `node_modules` of each mini app. Everything is nicely isolated and works very well.
### Bundle/Gem
Bundles approach is slightly different. You use `Gemfile` to specify your dependencies. After running `bundle install` the gems will be put into a system wide location. That means that if I have an app that requires different versions of a gem within its mini-apps then it wont work.
Work arounds that make no sense to me:
* I am aware that there is a `bundle install --deployment`, but its
used only for deployments in production. How is my code supposed to
work in development?
* Also, I am aware that you have an options to require a specific
version of the gem in your code but that beats the convenience of
having `Gemfile` with specific versions in it. It also makes no sense
in production environment since you already have `bundle install
--deployment`.
I am 100% sure I'm missing something very trivial here. Please point me into the right direction. | I found the 'answer'.
Ruby unlike Node.js does not have a built in support for local node\_modules like implementation. Thus you have to use Bundler. But to use the dependencies in your code you need to let Ruby know where these dependencies are located. Bundler makes it easy for you with the following lines in your app code:
```
require 'rubygems'
require 'bundler/setup'
```
This will read your Gemfile.lock and apply proper paths when your require something form your app. This is the part that I missed.
You can also use `bundle exec {rubygem}` to run gems that are installed by bundler for your app and not those that are installed globally.
I hope this helps someone! |

178610 | I'm trying to make a user control in wxWidgets to represent a channel in an audio mixer. So, each channel has a standard set of controls inside itself (some sliders, buttons, etc..).
So inside my class I have a sizer in which I add the various child controls I need. So far that works.
But the problems I have are
* if I derive from wxPanel, the layout of the control works as I expect it (it gets expanded in the sizer to fit the child controls), however none of the children get any events (like EVT\_LEFT\_DOWN etc). I tried connecting an event for the main control that runs event.Skip() but that didn't help.
* If I change my class to derive from wxControl instead (or wxFrame, or possibly a number of others I tried), the child controls *do* get events, but the whole thing doesn't get expanded in the sizer it's located in, it just gets drawn as a tiny box (some 10-20 square px) even though the child controls take up much more space.
Any ideas?
*Update:*
**mangoMixerStrip.cpp**
```
mangoMixerStrip::mangoMixerStrip(wxFrame* parent, HostChannel* channel) : wxPanel(parent)
{
myChannel = channel;
SetBackgroundColour(wxColour(172,81,90));
wxBoxSizer* s = new wxBoxSizer(wxVERTICAL);
// some custom controls i made which all work fine when added like any other control, derived from wxPanel also
faderPan = new mangoFader(parent, 200, false, 55);
faderGain = new mangoFader(parent, 200, true, 126);
buttonSolo = new mangoButton(parent, false, ButtonGraphic::Solo);
s->Add(faderPan);
s->Add(buttonSolo);
s->Add(faderGain);
this->SetSizer(s);
this->Connect(wxEVT_LEFT_DOWN, wxMouseEventHandler(mangoMixerStrip::mouseDown)); // this function simply contains event.Skip()
}
```
**in my main wxFrame**
```
mangoFrameMain::mangoFrameMain(wxWindow* parent) : FrameMain( parent )
{
HostChannel* h = new HostChannel();
h->setName("what up"); // these 2 lines unrelated to the UI
mangoMixerStrip *test = new mangoMixerStrip(this, h);
this->GetSizer()->Add(test, 1, wxFIXED_MINSIZE, 0);

Change line:

1. last about 1 to 2 months
* be done individually
* have web interface would be great
* doesn't necessary have to go deep in maths, but some would be great

Since mortgages on home are much more common, it's typically inferred that a "mortgage" means a loan on a house (or possibly on a multi-family structure or other type of building). The reason that "land loans" are specified may be because the *conditions* of such a mortgage are very different. With a home mortgage, there will be restrictions on what you can use the building for. i.e. can you rent it out or do you have to occupy it? Can you make renovations that materially impact the house's value without the bank's consent? What type of insurance must be carried?
With a land loan the restrictions are different (and probably simpler). What can you put on the land? What modifications to the land can you make? etc. So they are also technically mortgages but are less common and thus have more specific descriptions.

The loan document *should* specify what the collateral for the loan is. So, for example, you couldn't take out a home mortage and use a boat as collateral. Now, if you had a paid-for house, you could take out a mortgage on the *house* and use the *money* to buy a boat, but the house would still be the collateral for the loan. |

I'm using up-to-date version of `Microsoft.ServiceBus.dll` NuGet package (2.4.0.0), so answers from Google "certificate validation is off by default in ServiceBus 1.8" are useless - I had not turned any validation to ON, and moreover - it works many hours in a row and fails only once every 2-3 days.
Similar [answer](https://stackoverflow.com/questions/24171931/azure-hosted-service-bus-the-x-509-certificate-cn-servicebus-windows-net-is-n) about self-hosted applications are not suitable too - website is running inside Azure, hosting VMs are manages by MS staff, I'm not allowed to update any root certificates.
Does anybody know why ServiceBus client decides to check SSL cert sometimes and how to disable this behaviour?
**UPD:**
I added `<add key="Microsoft.ServiceBus.X509RevocationMode" value="NoCheck"/>` in `appSettings` in `web.config` two weeks ago - no difference.
Also Reflector shows that 'NoCheck' value is default in `Microsoft.ServiceBus.Configuration.ConfigurationHelpers.GetCertificateRevocationMode()` | A change in Connectivity Mode *could* solve your problem.
```
ServiceBusEnvironment.SystemConnectivity.Mode = ConnectivityMode.Https

So I figure that the certificate will only be fetched once in this scenario, and that may introduce an extra latency at that point, and then it is used forever after. It seems logical that the risk of getting your exception is thus reduced considerably. |

182447 | Currently, my app allows the user to click on a "default avatar pic" and then select from a group of images. This image is then returned to the first activity via "startActivityForResult".

182716 | I was reading a chapter on effective Java that talks about the advantages of keeping only one instance of an immutable object, such that we can do object identity comparison `x == y` instead of comparing the values for identity.
Also, POJOs like [`java.awt.RenderingHints.Key`](http://docs.oracle.com/javase/1.4.2/docs/api/java/awt/RenderingHints.Key.html) often use the one-instance-per-unique-immutable design pattern:

using this as reference but now with different scenario [SQL Server query : get the sum conditionally](https://stackoverflow.com/questions/29597690/sql-server-query-get-the-sum-conditionally)
**explanation:**
Item, Sales, and remarks columns are given column from a database, New Sales column is a formulated column where in, it is getting the sum of items with the same keyword remarks except the default n/a remarks.
(regardless the remarks is not fully identical, at least there's a common similarity like what is on the image above - item 5 has "new" in it, still it sums up with item 6 because of their similar keyword found "small")
**code used**
**FIRST OPTION- using partition** - This doesn't work because when the remarks is not identical to each other it will not get the sum properly (for item5 and item6)
```
CASE
WHEN ([remarks] not like '%big%') AND ([remarks] not like '%PAENGS%')
THEN sales
ELSE SUM(sales) OVER(PARTITION BY [remarks])
END as 'New Sales'
```

d.*,

CASE
WHEN ([remarks] not like '%big%') or ([remarks] not like '%small%')

183504 | I am currently learning C++ and I am having an odd issue with threads. I've done lots of threaded stuff in Java and C# and not had an issue. I am currently trying to replicate a C# library that I have in C++ with a library and a test app.
In main.cpp I create an instance of a `InitialiseLibrary` class and call the method `initialise`. This does config loading and is then supposed to start a thread which stays running through the duration the application is running. I am expecting this thread to start, and then my initialise function returns true where I then continue and I create an instance of a test class which writes to a log file every 1 second.
Below is main.cpp
```
InitialiseLibrary initLibrary("config.ini");
if (!initLibrary.initialise(1))
{
cout << "Failed to initialise library" << endl;
return EXIT_FAILURE;
}
TestClass testClass;
testClass.writeSomeLogsInThread();
cout << "The library config log file is: " << GlobalConfig::GeneralConfig::logFile << endl;
```
In my Initialise method (which is in the library) I have:
```
bool InitialiseLibrary::initialise(int applicationAlarmID, int applicationTerminationTimeout)
{
//statusManager.setApplicationStatus(StatusManager::ApplicationStatus::Starting);
if (!this->loadInconfiguration(applicationAlarmID))
{
cout << "*****Failed to configuration. Cannot continue******" << endl;
return false;
}
GlobalConfig::libraryInitialised = true;
LogRotation logRotation;
logRotation.startLogRotation();
BitsLibrary bitsLibrary;
//Set up the signal handler if its needed, 0 means it terminates instantly, doesn't wait -1 is don't use signal handler
if (applicationTerminationTimeout >= 0)
{
bitsLibrary.setupSignalHandler(applicationTerminationTimeout);
}
return true;
}
```
As you can see, I read in the configuration and I then call `logRotation.startLogRotation().
Where I have the following code:
```
void LogRotation::startLogRotation()
{
//Is the configuration successfully loaded
if (!LogRotateConfiguration::configurationLoaded)
{
throw exception("Log Rotation not initialised");
}
BitsLibrary bitsLibrary;
stringstream logStream;
logStream << "Log rotation thread starting, monitor cycle time is " << LogRotateConfiguration::archiveSleepTimeInSeconds << " second(s)";
bitsLibrary.writeToLog(logStream.str(), "LogRotation", "startLogRotation");
thread logRotationThread(&LogRotation::logRotationThread, this);
logRotationThread.join();
}
void LogRotation::logRotationThread()
{
BitsLibrary bitsLibrary;
while (bitsLibrary.getApplicationStatus() == StatusManager::ApplicationStatus::Starting || bitsLibrary.getApplicationStatus() == StatusManager::ApplicationStatus::Running)
{
bitsLibrary.writeToLog("Running log monitoring");
this_thread::sleep_for(chrono::seconds(LogRotateConfiguration::archiveSleepTimeInSeconds));
}
stringstream logStream;
logStream << "Log rotation archive monitoring stopped. Current application status: " << bitsLibrary.getApplicationStatus();
bitsLibrary.writeToLog(logStream.str(), "LogRotation", "logRotationThread");
}
```
Here I am expecting, `startLogRotation()` to start run the method `logRotationThread` within a thread, the thread starts, and the startLogrotation() method finishes and backs through the stack to the initialise() method where that returns true, back up to main where I can then call my TestClass method within a thread.
For some reason though, the thread starts and keeps logging every few seconds `Running log monitoring` so I know the thread has started, yet it doesn't seem to return back to the initialise function to return true, so the app gets stuck on that function call and doesn't go any further.
I've read that you need to run `join` on the thread to keep it in sync with the main thread, otherwise the main thread exits, while the new threads are running and cause a SIGABRT which in deed it does, but having the join there seems to stop the method returning. | Your main thread blocks at this line, waiting for the logRotationThread to end.
```
logRotationThread.join();
```
Your main thread should go and do whatever work it needs to do after spawning the other thread, then only when it has nothing left to do should it `join()` the log rotate thread. |
183653 | I have a Excel sheet, which includes many groups and subgroups. Each subgroup has their own subtotal. And as long as I can't know how many lines users will require for the subgroups, I only left 3 rows blank for each subgroup and created a button which triggers Automatically Copy and Insert Copied Row macro.
Now I need to avoid users to trigger the button while they are on the First and the Last row of any subgroup.

This works as advertised to publish my React app at ***myusername*.github.io**, but it makes it impossible to make further changes to the source files since they are no longer available in the working directory.
I understand that GitHub *project* pages work differently than GitHub user pages (they allow the application to be published from the `gh-pages` branch rather than `master`).

[Finding duplicate values in multiple colums in a SQL table and count](https://stackoverflow.com/questions/70512433/finding-duplicate-values-in-multiple-colums-in-a-sql-table-and-count)
I have the following table structure:
```
id name1 name2 name3 ...
1 Hans Peter Frank
2 Hans Frank Peter
3 Hans Peter Frank
4 Paul Peter Hans
.
.
.
```
I use the following command to display the duplicates and the counts:
```
SELECT COUNT(name1), name1, name2, name3
FROM table
GROUP BY name1, name2, name3
HAVING (COUNT(name1) > 1) AND (COUNT(name2) > 1) AND (COUNT(name3) > 1)
```
This command gives me a count of 2. I would like to know how the second line could also be counted as a dublicate.
Unfortunately, the solution to the original question ([Finding duplicate values in multiple colums in a SQL table and count](https://stackoverflow.com/questions/70512433/finding-duplicate-values-in-multiple-colums-in-a-sql-table-and-count)) does not work for char | First normalize the table with `UNION ALL` in a CTE to get each of the 3 names in a separate row.
Then with `ROW_NUMBER()` window function you can rank alphabetically the 3 names so that you can group by them:
```
WITH cte(id, name) AS (
SELECT id, name1 FROM tablename
UNION ALL
SELECT id, name2 FROM tablename
UNION ALL
SELECT id, name3 FROM tablename
)
SELECT COUNT(*) count, name1, name2, name3
FROM (
SELECT id,
MAX(CASE WHEN rn = 1 THEN name END) name1,
MAX(CASE WHEN rn = 2 THEN name END) name2,
MAX(CASE WHEN rn = 3 THEN name END) name3
FROM (
SELECT *, ROW_NUMBER() OVER (PARTITION BY id ORDER BY name) rn
FROM cte
)
GROUP BY id
)
GROUP BY name1, name2, name3
HAVING COUNT(*) > 1;
```
Another way to do it, that uses similar logic to your previous question with numeric values, with string function `REPLACE()` instead of window functions, but works only if the 3 names in each row are different:
```
SELECT COUNT(*) count,
MIN(name1, name2, name3) name_1,
REPLACE(
REPLACE(
REPLACE(name1 || ',' || name2 || ',' || name3, MIN(name1, name2, name3), ''),
MAX(name1, name2, name3), ''), ',', ''
) name_2,
MAX(name1, name2, name3) name_3
FROM tablename
GROUP BY name_1, name_2, name_3
HAVING COUNT(*) > 1;

I can't figure out what is wrong. Even if you change the order of installation it says it can't find the other. | After installing one of your packages and downloading the other…
You're not including `testsuite/__init__.py` and `testsuite/prettyprint/__init__.py` in the source files.
The docs on [Namespace Packages](http://peak.telecommunity.com/DevCenter/setuptools#namespace-packages) the `setuptools`/`pkg_resources` way explains:
>
> Note, by the way, that your project's source tree must include the namespace packages' `__init__.py` files (and the `__init__.py` of any parent packages), in a normal Python package layout.

If you don't actually install these files, they don't do any good. You just end up with a `testsuite` with nothing in it but `prettyprint`, and that has nothing in it but `outcomes`, so `testsuite` and `testsuite.prettyprint` are not packages at all, much less namespace packages. |

$query->select(['created_by_id', 'created_by_name']);
}])
->where('is_active', '=', 0)
->orderBy('id', 'desc')
->get();
```
I am getting data from `User` but getting blank in `SelDetails`
```php
[relations:protected] => Array
(
[SelDetails] =>
)
```
Please correct me. | guys thanks for your precious response on this issue. i got the solution via following way.
**changes in "User" model Relation With 'SelDetails'**
```
public function SelDetails {
#return $this->belongsTo('App\UsersDetails', 'users_id');// the old one
return $this->hasOne('App\UsersDetails', 'users_id');
}
```
**changes in "UserController"**
```
$users = User::with('SelDetails')->where('is_active', '=', 0)->orderBy('id', 'desc')->get();
```
that's the changes that I have made and got the result

186074 | Inside `c:\test\` I have:
* .\dir1
* .\dir2
* .\dir3
and
* file1.txt
* file2.txt
* file3.txt
* file4.txt
I want to compress only `dir1`, `dir2`, `file1.txt` and `file2.txt`
I use the following script to compress selected folders
```
$YourDirToCompress="C:\test\"
$ZipFileResult=".\result.zip"
$DirToInclude=@("dir1", "dir2")
Get-ChildItem $YourDirToCompress -Directory |
where { $_.Name -in $DirToInclude} |
Compress-Archive -DestinationPath $ZipFileResult -Update
```
How would I be able to add my selected files (`file1.txt` & `file2.txt`) to final compressed `result.zip`?
Ideally I want the compression to happen in one go meaning I pass the list of selected files and folders and then do the compression. | Try something like this:
```
Get-ChildItem -Path $YourDirToCompress | Where {$_.Name -in $DirToInclude} | Compress-Archive -DestinationPath $ZipfFileResult -Update
```
`Compress-Archrive` is capable of zipping both files and directories. So in this code we are using `Get-ChildItem` without the `-Directory` flag which will return all files and directories at the root-level of `$YourDirToCompress`
Then we pass those files/folders to the `Compress-Archive` cmdlet just as we did before.
*Assuming that the files are at the root level of `$YourDirToCompress`* |
187010 | I'm writing a custom xml deserializer for an iphone app. As you can see below, I'm looping through all the list elements in the xml, I have debugged it, and with each loop there is a new and different element. The problem is that the xpath helper methods (there are similar ones to the one posted below, but for int and decimal) always returns the same value.
For example - 1st loop's xml "SomeValue" value will be "abc" and the helper method will return "abc", second item comes around and its xml "SomeValue" is "XYZ", but the helper method will still return "abc".
I'm new to iphone/objective c/memory managment so it could be any number of things. I just cant determine what the problem is :( could someone please offer some help?
```
-(void) deserializeAndCallback:(GDataXMLElement *)response
{
NSError * error;
NSArray *listings = [response nodesForXPath:@"//ListingSummary" error:&error];
NSMutableArray *deserializedListings = [[NSMutableArray alloc] init];
//loop through all listing elements, create a new listing object, set its values, and add
//it to the list of deserialized objects.
if(listings.count > 0)
{
for (GDataXMLElement *listingElement in listings)
{
Listing *list = [[Listing alloc] init];
//xpath helper function (shown below), just to get the value out of the xml
list.someValue = [QuickQuery getString:listingElement fromXPath:@"//SomeValue"];
[deserializedListings addObject:list];
}
}
if([super.delegate respondsToSelector: @selector(dataReady:)])
{
[super.delegate dataReady:deserializedListings];
}
}
+(NSString *) getString:(GDataXMLElement *)element fromXPath:(NSString *)xPath
{
NSError *error;
NSArray *result = [element nodesForXPath:xPath error:&error];
if(result.count > 0)
{
GDataXMLElement *singleValue = (GDataXMLElement *) [result objectAtIndex:0];
return singleValue.stringValue;
[singleValue release];
}
return nil;
[error release];
[result release];
}
```
EDIT: ok... I found a bit more info. Inside the helper function, the nodesForXpath method returns all the nodes from the entire xml, not just the current element I'm busy with. Does GDataXMLElement keep reference to its parent elements at all?
Example of what the xml looks like
```
<ListingSummary>
<SomeValue>abc</SomeValue>
</ListingSummary>
<ListingSummary>
<SomeValue>jhi</SomeValue>
</ListingSummary>
<ListingSummary>
<SomeValue>xyz</SomeValue>
</ListingSummary>
``` | It looks OK for me. Although the releases inside the getString:fromXPath: aren't necessary (you don't need to release parameters entered into a method or objects obtained from a NSArray. The proper way to release an object from a NSArray is removing it from the array, as for objects passed as a parameter, if you want to release it you should do it after you call the method.
The problem to your question must be somewhere else. |
187293 | I am working with ARM mali 72 on my Android smartphonne.
I would like to use the output buffer fron OpenCL to render it into OpenGL like a texture.
I have no problem with openCL alone nether openGL alone.
I got no cloud to how to use both in the same application.
The goal is to use mY output OpenCL and send it to openGL.
Some peice of code step by step would be very nice.
I can use openCL 2.0 and opengl ES 3.0 on my smartphonne.
\*\*\*\*\*\*\*\*\*\*\*\*\*\* ADDED THE 30/09/2020 \*\*\*\*\*\*\*\*\*\*\*\*
It Look like I need more information on how to manage my problem.
So my configuration is ! I got Java OpenGL ES Application to already develloped. I retreive the camera frame from Camera.OnPreviousFrame then a send it to OpenCL using JNI.
So i would like to Get the EGL display from Java OpenGL ES Send it through JNI and then Compute my openCL kernel send It back to java OpenGL ES.
I know how to retreive data from OpenCL, transform it to bitmap and use SurfaceTexture and GL\_TEXTURE\_EXTERNAL\_OES to display it into openGL ES.
My problem is how to Retreive EGL display from java OpenGL ES. How to send it to C++, this i can manage to find out using JNI. But i do not know how to implement the C++ part using EGL and OpenCL.
The Answer from BenMark is interresting concerning the processing but I am missing some part. It is possible to use my configuration, using java openGL ES or do i nedd to do all the EGL, openGL, openCL code in native ?
Thanks a lot for help me to anderstand the problem and try to find a solution. ;)) | You could do it with a recursive template like this :

I have the right parenthesis following the lower-case Roman numerals `i`, `iii`, and `v` aligned, and I would like to have the right parenthesis following the lower-case Roman numerals `ii`, `iv`, and `vi` aligned.
