apply the edge detection in an image segmentation <p>I have two questions about snake edge detection. The first question is, in openCV there is a function cvSnakeImage(src,points,.......), what does the points parameter mean?</p> <p>The second questions is: I want to apply this function on the part surrounded by an edge that I have already made, how can I do this?</p> <p>This is my code for edge detection:</p> <pre><code>cvCanny(img_bw, img_canny , thresh, thresh * 50, 3); cvFindContours(img_canny, contour, &amp;contours, sizeof(CvContour), CV_RETR_TREE, CV_CHAIN_APPROX_SIMPLE); </code></pre>

TensorFlow network not training? <p>I had a really weird time with TensorFlow the last days and can not think of what's going wrong atm.</p> <p>I have built this network: <a href="http://pastebin.com/GZaX4aYN" rel="nofollow">link</a>. It is a copy of TensorFlow's MNIST example.</p> <p>Basically, what I did, is altering the network from taking 28x28x1 images (MNIST greyscale) to 600x800x1 images (some images I took on my own, webcam with a relatively clean background and one object at different locations).</p> <p>What I wanted to do is playing around with such a CNN and have it output the x-location of the object in the image. So one single output neuron.</p> <p>However, no matter what I tried, the network is always outputting 1.0. Even (when you look at my testing section at the end of the code) when I feed all ones, all zeros or all random numbers into the network.</p> <p>Of course, since I have only 21 labeled training and 7 labeled test pictures I expected the performance to be really bad (since 800x600 pixel images are huge for neural networks and locating an object isn't easy).</p> <p>...but I have no idea at all why the network always outputs 1.0 even if it is fed with nonsense. Any ideas?</p>

Get frame by frame data from mp4 using C# and .NET 2.0 <p>I'm currently developing using Unity 3D, however my background is Apple development. In iOS/OSX development I can use <code>AVFoundation</code> to load an mp4 and get frame by frame data from it as it plays in BGRA format.</p> <p>I was wondering what the equivalent of this is for .NET (Unity uses .NET 2.0)?</p> <p>I know it's possible to call functions in an Objective-C++ file from unity but I need a way to do this on any platform not just iOS.</p>

Convert String to Variable Name <p>I need get combobox by string. Not worked.</p> <pre><code> for (int i = 0; i &lt; Slots.Count; i++) { var field = (ComboBox)this.GetType().GetField("cbSlots" + i).GetValue(this); field.DataSource = Slots[i.ToString()]; } </code></pre>

<p>Assign to learningTime the System.currentTimeMillis() value so it's 0 > 3000</p> <pre><code>learningTime = System.currentTimeMillis() </code></pre> <p>And, anyway you will block the main thread with this code. </p> <p>That can be an example of Handler</p> <pre><code>final Handler handler = new Handler(); Runnable runnable = new Runnable() { @Override public void run() { handler.postDelayed(this, 3000); } }; handler.postDelayed(runnable, 3000); </code></pre> <p><a href="http://developer.android.com/reference/android/os/Handler.html" rel="nofollow"><code>Handler class</code></a> <a href="http://developer.android.com/reference/java/lang/Runnable.html" rel="nofollow"><code>Runnable</code></a> <a href="http://developer.android.com/reference/android/os/Handler.html#postDelayed%28java.lang.Runnable,%20long%29" rel="nofollow"><code>Handler postDelayed</code></a></p> <p>Anyway, you don't need anymore <code>learningTime</code> and <code>i</code> (?)</p>

Set "Image File Execution Options" will always open the named exe file as default <p>As <a href="http://untidy.net/blog/2009/11/03/replacing-notepad-with-pn-via-image-file-execution-options/" rel="nofollow noreferrer">this link suggests</a>, I want replace <code>Notepad.exe</code> with <code>Notepad2.exe</code> using "<strong>Image File Execution Options</strong>" function by run the command</p> <pre><code>reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\notepad.exe" /v "Debugger" /t REG_SZ /d "\"c:\windows\Notepad2.exe\" /z" /f </code></pre> <p>But when I run <strong>notepad</strong> it still opens the file </p> <blockquote> <p>c:\windows\notepad.exe</p> </blockquote> <p>in notepad2.exe as a text file by default. </p> <p>Is there a way to avoid that?</p> <p>I know using this tech Notepad.exe will as the first param passed to Notepad2.exe. but I don't know how to avoid this :(</p>

How can I design input without knowing in advance how many values will be entered? <p>I want to input based on how many values a user inputs, without expecting an exact number of values. </p> <p>In my program I want user to input integer(s) but the problem is that I want to allow the user to either input one or two space separated integers.</p> <p>So,if user enters two space separated integers,they should get stored in variables a and b,and if he enters just one number before pressing enter then it should get stored in a,and the program should proceed further without waiting for the second number.</p> <p>What is the best way to do that?</p>

<p>Try to use a subquery with a LIMIT clause, e.g. -</p> <pre><code>SELECT i_s.pid, p_r.range_id as PriceRangeID, COUNT(p_r.range_id) as PriceGroupTotal FROM (SELECT * FROM indx_search WHERE i_s.word = 'memory' ORDER BY i_s.pid ASC LIMIT 0 , 20) i_s LEFT JOIN windex_mem w_m ON w_m.word = i_s.word LEFT JOIN price_range p_r ON p_r.pid = i_s.pid GROUP BY i_s.pid, PriceRangeID </code></pre>

<p>I agree, there are better ways to create a header for CCDA documents, however, if you'd like to stick with your solution here is the missing part:</p> <pre><code>var clinicalDocument = new XML ("&lt;clinicalDocument&gt;&lt;/clinicalDocument&gt;"); clinicalDocument['realmCode']['@code']="US"; clinicalDocument['typeId']['@extension']="POCD_HD000040"; clinicalDocument['typeId']['@root']="2.16.840.1.113883.1.3"; createSegment('templateId', clinicalDocument); createSegment('templateId', clinicalDocument, 1); createSegment('templateId', clinicalDocument, 2); clinicalDocument['templateId'][0]['@root']="2.16.840.1.113883.10.20.22.1.1"; clinicalDocument['templateId'][1]['@root']="2.16.840.1.113883.10.20.24.1.1"; clinicalDocument['templateId'][2]['@root']="2.16.840.1.113883.10.20.24.1.2"; clinicalDocument['documentationOf']['serviceEvent']['performer']['assignedEntity']['code']['@codeSystemName']="Healthcare Provider Taxonomy"; clinicalDocument['documentationOf']['serviceEvent']['performer']['assignedEntity']['code']['@displayName']="Adult Medicine"; logger.info("Data : "+clinicalDocument); </code></pre>

<p>Youd need to pad your data with at least order n zeros; then you could set stride[n]==-stride[m] to achieve the intended effect, and avoid allocating order n*m zeros.</p> <p>But something tells me there must be a more elegant solution to your problem, if you take a bigger-picture view.</p>

<p>the function <code>Ei</code> does either not exist or is not in your matlab path.</p> <p><strong>Edit:</strong> this function seems to be new in matlab 2011b, so if you are using an older version of matlab, the function won't be there -> error.</p> <p><strong>Edit2:</strong> do you have the <strong>Symbolic Math Toolbox</strong> installed?</p>

<p>Maybe the <code>models</code> module has an <code>__all__</code> which does not include what you're looking for. Anyway, <code>from ... import *</code> is <strong>never</strong> a good idea in production code -- we always meant the <code>import *</code> feature for interactive exploratory use, <em>not</em> production use. Specifically import the module you need -- use that name to qualify names that belong there -- and you'll be vastly happier in the long run!-)</p>

<p>I don't know what happened, but I disabled the USB WiFi dongle and switched to a cabled network, and it started working. don't know what the reasons were, but I am happy now that it worked.</p> <p>May be this is useful to others too!</p>

<p>The issue is that your app does not have a module named <code>uwsgi</code>. You change the directory to <code>/home/user/appname</code> but it looks like the actual module would be <code>appname.uwsgi</code> since the <code>uwsgi.py</code> file lives within <code>/home/user/appname/appname/uwsgi.py</code>.</p> <p>Typically though, you don't need to specify both <code>--wsgi-file</code> and <code>--module</code> so I would either do</p> <pre><code>uwsgi --http :9010 --chdir /home/user/appname --wsgi-file /home/user/appname/appname/wsgi.py </code></pre> <p>or</p> <pre><code>uwsgi --http :9010 --chdir /home/user/appname --module appname.uwsgi </code></pre> <p>I personally prefer the second.</p>

Strange parallel loop behaviour int v long int <p>I have some code i'm running in parallel using an OMP for loop, up to large numbers. The code (with unimportant bits removed) is as follows (apologies if it's a mess/hard to follow):</p> <pre><code>long int primePos=-1; unsigned long long int odd; int primeFactor; while(fileNumber&lt;=nFiles) { percPrev=0; compCounter=0; #pragma omp parallel for shared(numberElements, iStart, iEnd,tau, wall0) schedule (guided) private(primePos,odd,primeFactor) for(unsigned long long int i=iStart;i&lt;=iEnd;i++){ #pragma omp atomic tau++; odd=2*i-1; if(!IsPrime(odd)){ primeFactor = getPrimeFactor(odd); for(long int j=0;j&lt;PrimeDatL;j++){ if(PrimeDataT[j]==primeFactor){ primePos=j; break; } } #pragma omp critical { if(compCounter+1&gt;numberElements){ cout&lt;&lt;"Array overflow, exiting."&lt;&lt;endl; exit(0); } InsertElement(odd,primeFactor,pHVector,primePos); compCounter++; } } } iStart=iEnd+1; iEnd=min(iEnd+numberElements,maxVal); fileNumber++; } </code></pre> <p>The idea is that I go through all the odds up to <code>2^n</code>, if they're not prime I take the smallest prime factor and put it, along with the odd, in a vector which is arranged in a particular fashion. The variable <code>primePos</code> simply denotes which spot in this vector it goes into, and isn't a particularly large number so it was originally simply an <code>int</code> type. </p> <p>However, for larger values of n ~33, I found that InsertElement() was throwing an exception because <code>primePos</code> was huge, much larger than it could possibly be as defined in the for loop which searches for the position of <code>primeFactor</code> in <code>PrimeDataT</code>. This was rectified (well, it compiles and runs and for low values of n i can verify in mathematica that it's correct) by changing <code>primePos</code> from <code>int</code> to <code>long int</code>, but i've no idea why that should be the case and I'd like to know before I continue, in case I'm missing something important.</p> <p>tl;dr = how can primePos take a value larger than PrimeDatL if it is declared as an <code>int</code> instead of <code>long int</code>? Thanks in advance!</p>

Adding a ContactsContract.CommonDataKinds.Event to Android contacts, does not show up <p>I'm trying to add a birthday event to contacts but the event <strong>doesn't show up</strong> when displaying the contact in the People app. When going into 'Edit' mode of the contact, an event DOES show up, but no selected date (see attached screenshot) as if the format is wrong.</p> <p>When inspecting the contacts2.db in an sqlite viewer, it seems that the date are formatted just fine, like other events/birthdays that are properly showing (see attached image. First row is a manually entered birthday through the app, and the second row, was added by my app and doesn't show)</p> <p>Here is the code I am using, which follows the SampleSyncAdapter from the $ANDROID_HOME sdk</p> <pre><code>public ContactOperations addBirthday(Date date) { mValues.clear(); if(date!=null) { mValues.put(ContactsContract.CommonDataKinds.Event.TYPE, ContactsContract.CommonDataKinds.Event.TYPE_BIRTHDAY); mValues.put(ContactsContract.CommonDataKinds.Event.START_DATE, BIRTHDATE_FORMATTER.format(date)); mValues.put(ContactsContract.CommonDataKinds.Event.MIMETYPE, ContactsContract.CommonDataKinds.Event.CONTENT_ITEM_TYPE); addInsertOp(); } return this; } private void addInsertOp() { if (!mIsNewContact) { mValues.put(ContactsContract.CommonDataKinds.Phone.RAW_CONTACT_ID, mRawContactId); } ContentProviderOperation.Builder builder = newInsertCpo(ContactsContract.Data.CONTENT_URI, mIsSyncOperation, mIsYieldAllowed); builder.withValues(mValues); if (mIsNewContact) { builder.withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, mBackReference); } mIsYieldAllowed = false; mBatchOperation.add(builder.build()); } </code></pre> <p><img src="https://i.stack.imgur.com/8YqnP.png" alt="enter image description here"></p> <p><img src="https://i.stack.imgur.com/x7jIe.png" alt="enter image description here"></p>

Pan class in Flash AS3 <p>I have a movieclip and I am going to add a pan feature to it. I want to add the pan as it's own class that the movieclip can reference.</p> <p>When I create the pan class, I send the movieclip to it so I have it's position properties at all times.</p> <p>What is the best way to access the stage in the pan class? I will need to be able to get the stage mouseX, mouseY, stageWidth, and stageHeight.</p> <p>Right now, I have the pan class extend a sprite object and actually add it as a child of the movieclip I want to pan.</p> <p>Would it be better to just send the stage itself into the pan class as well or is there a better way than this?</p>

<p>how about that:</p> <pre><code>value = value &gt; 0 ? value: ~value + 1 </code></pre> <p>its based on the fact that negative numbers are stored as 2's complement to there positive equivalent, and that one can build the 2's complement by first building the 1's complement and adding 1, so </p> <pre><code> 5 -&gt; 0000 0101b -5 -&gt; (1111 1010b) + 1 -&gt; 1111 1011b </code></pre> <p>what I did was basically to reverse this, so</p> <pre><code>-5 -&gt; 1111 1011b 5 -&gt; (0000 0100b) + 1 -&gt; 0000 0101b </code></pre> <p>I know it's a bit late but just had the same issue and landed here, hope this helps.</p>

<p>I assume what you want to do is that when the button is clicked, it should open the same URL that was present in href. If this is the scenario, you can just add an onclick event handler to the button i.e onclick="navigate('<em>Your URL here</em>');". </p> <p>You can also set the onclick event to call a javascript function which in turn can open a modal/normal popup window for you</p>

Removing 'Allow' response header <p>I have a web-app developed using Spring-MVC, Spring-Security and hosted on Tomcat 7. As a security measure, I have also whitelisted only certain HTTP methods in web.xml as follows:</p> <pre><code>&lt;security-constraint&gt; &lt;web-resource-collection&gt; &lt;web-resource-name&gt;restricted methods&lt;/web-resource-name&gt; &lt;url-pattern&gt;/*&lt;/url-pattern&gt; &lt;http-method-omission&gt;GET&lt;/http-method-omission&gt; &lt;http-method-omission&gt;POST&lt;/http-method-omission&gt; &lt;http-method-omission&gt;DELETE&lt;/http-method-omission&gt; &lt;/web-resource-collection&gt; &lt;auth-constraint /&gt; &lt;/security-constraint&gt; </code></pre> <p>At this point, what I would expect is that if I made an excluded http method call to any endpoint, then I would get a 403 response - and this setup works. But the 403 response also includes a "Allow" header as follows:</p> <pre><code>Allow: GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS, PATCH </code></pre> <ol> <li>Is blacklisting OPTIONS not a supported/recommended thing?</li> <li>Why is the list of allowed http methods different from what I have configured?</li> <li>I'm assuming Tomcat is the one adding the Allow header to the response - is that right?</li> <li>And how can I configure tomcat (or spring if that is adding the header) to not add this header to the response?</li> </ol>

How get Admin credentials? I am the Admin already <p>My new computer have Windows 8.1 64-bit Spanish version; the previous one had Windows XP and I never messed before with Credentials, Privileges, etc. In my computer there is just one user account that is marked as Administrator: "They have access to all files and programs stored in the computer". However, if I open a command-line window and execute <code>chkdsk</code> I get this:</p> <pre><code>Microsoft Windows [Versión 6.2.9200] (c) 2012 Microsoft Corporation. Todos los derechos reservados. C:\Users\Antonio&gt; chkdsk Acceso denegado porque no tiene privilegios suficientes. Invoque esta utilidad ejecutándola en modo elevado. </code></pre> <p>That is: "Access denied because you have not enough privileges. Invoke this utility executing it in elevated mode". I tried to use <code>runas</code> command, but I don't understand what parameters I must give.</p> <p>I get the same result when I execute <code>fsutil</code> with these options:</p> <pre><code>C:\Users\Antonio&gt; fsutil fsinfo ntfsInfo C: Error: Acceso denegado. </code></pre> <p>How can I execute these programs in my computer?

<p>So what's happening is your <code>draw::before/draw::after</code> elements are 0px tall at the start of your transition. That means the border radius is going to be very skewed. </p> <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false"> <div class="snippet-code"> <pre class="snippet-code-css lang-css prettyprint-override"><code>button { background: none; border: 0; box-sizing: border-box; color: #f45e61; font-size: inherit; font-weight: 700; padding: 200px; text-align: center; margin: 20px; position: relative; vertical-align: middle; } button::before, button::after { box-sizing: border-box; content: ''; position: absolute; width: 100%; height: 100%; } .draw { -webkit-transition: color 0.25s; transition: color 0.25s; border-radius: 70px; } .draw::before, .draw::after { border-radius: 70px; border: 30px solid transparent; width: 0; height: 0; } .draw::before { top: 0; left: 0; } .draw::after { bottom: 0; right: 0; } .draw:hover { color: #60daaa; } .draw:hover::before, .draw:hover::after { width: 100%; height: 100%; } .draw:hover::before { border-top-color: #60daaa; border-right-color: #60daaa; -webkit-transition: width 1.25s ease-out, height 1.25s ease-out 1.25s; transition: width 1.25s ease-out, height 1.25s ease-out 1.25s; } .draw:hover::after { border-bottom-color: #60daaa; border-left-color: #60daaa; -webkit-transition: border-color 0s ease-out 2.5s, width 1.25s ease-out 2.5s, height 1.25s ease-out 3.75s; transition: border-color 0s ease-out 2.5s, width 1.25s ease-out 2.5s, height 1.25s ease-out 3.75s; }</code></pre> <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;h1&gt;CSS Border Transitions&lt;/h1&gt; &lt;button class="draw"&gt;draw&lt;/button&gt;</code></pre> </div> </div> </p> <p>After enlarging/slowing down the animation you can see what the issue is.

Do temporary files get deleted even while the app is running? <h2>Background</h2> <p>On android, you can create temporary files as such (link <a href="http://developer.android.com/guide/topics/data/data-storage.html#InternalCache" rel="nofollow">here</a> and <a href="http://developer.android.com/reference/java/io/File.html#createTempFile%28java.lang.String,%20java.lang.String,%20java.io.File%29" rel="nofollow">here</a> for documentation) :</p> <pre><code>final File temp = File.createTempFile("myFile", ".tmp", context.getCacheDir()); </code></pre> <p>I'm developing an app that uses temporary files and when it's done with them (and on start of the app), it deletes them.</p> <h2>The question</h2> <p>The documentation says :</p> <blockquote> <p>When the device is low on internal storage space, Android may delete these cache files to recover space.</p> </blockquote> <p>Does it mean that files can get deleted even while my app is still running? In which cases would android be allowed to delete the files? </p> <p>In other words , can I assume that as long as I have the app running , android won't delete the files by itself, even if other apps create their own temporary files?</p>

<p>If you can't find a method, you can build one using ruby's <em>include?</em> method.</p> <p>Official documentation: <a href="http://www.ruby-doc.org/core-1.9.3/Array.html#method-i-include-3F" rel="nofollow">http://www.ruby-doc.org/core-1.9.3/Array.html#method-i-include-3F</a></p> <p>Usage:</p> <pre><code>array = [1, 2, 3, 4] array.include? 3 #=&gt; true </code></pre> <p>Then, you can do a loop:</p> <pre><code>def array_includes_all?( array, comparision_array ) contains = true for i in comparision_array do unless array.include? i contains = false end end return contains end array_includes_all?( [1,2,3,2], [1,2,2] ) #=&gt; true </code></pre>

<p>This approach will work with PostgreSQL but it'll tend to be pretty inefficient as you're updating each row twice - each update requires <em>two</em> transactions, two commits. The cost of this can be mitigated somewhat by using a <code>commit_delay</code> and possibly disabling <code>synchronous_commit</code>, but it's still not going to be fast unless you have a non-volatile write-back cache on your storage subsystem.</p> <p>More importantly, because you're committing the first update there is no way to tell the difference between a worker that's still working on the job and a worker that has crashed. You could probably set the token to the worker's process ID if all workers are on the local machine then scan for missing PIDs occasionally but that's cumbersome and race-condition prone, not to mention the problems with pid re-use.</p> <p>I would recommend that you adopt a <em>real</em> queuing solution that is designed to solve these problems, like ActiveMQ, RabbitMQ, ZeroMQ, etc. <a href="http://wiki.postgresql.org/wiki/PGQ_Tutorial" rel="nofollow">PGQ</a> may also be of significant interest.</p> <p>Doing queue processing in a transactional relational database <em>should</em> be easy, but in practice it's ridiculously hard to do well and get right. Most of the "solutions" that look sensible at a glance turn out to actually serialize all work (so only one of many queue workers is doing anything at any given time) when examined in detail. </p>

<p>Why not make the views layer-backed? You can then just apply an affine transform to the view's layer.</p> <pre><code>yourView.layer.transform = CATransform3DMakeRotation(M_PI_4, 0, 0, 1.0); </code></pre>

<p>If you only need to find direct members, you can use Attribute Scope Query (ASQ). This requires domain/forest functional level of 2003 (forgot domain or forest).</p> <pre><code>DirectoryEntry groupEntry = new DirectoryEntry("LDAP://&lt;server&gt;/&lt;group DN&gt;", "user", "pwd"); DirectorySearcher searcher = new DirectorySearcher(groupEntry); searcher.SearchScope = SearchScope.Base; searcher.AttributeScopeQuery = "member"; searcher.Filter = "(&amp;(objectCategory=person)(objectClass=user))"; searcher.PropertiesToLoad.Clear(); searcher.PropertiesToLoad.Add("name"); searcher.PropertiesToLoad.Add("mail"); searcher.PropertiesToLoad.Add("displayName"); foreach (SearchResult result in searcher.FindAll()) { Console.WriteLine(result.Path); } </code></pre> <p>For nested group members, you may use the LDAP_MATCHING_RULE_IN_CHAIN matching rule. This requires domain/forest functional level of 2008 R2 (again, forgot domain or forest).</p> <pre><code>DirectoryEntry rootEntry = new DirectoryEntry("GC://&lt;server&gt;", "user", "pwd"); DirectorySearcher searcher = new DirectorySearcher(rootEntry); searcher.SearchScope = SearchScope.Subtree; searcher.Filter = "(&amp;(objectCategory=person)(objectClass=user)(memberOf:1.2.840.113556.1.4.1941:=&lt;group DN&gt;))"; searcher.PropertiesToLoad.Clear(); searcher.PropertiesToLoad.Add("name"); searcher.PropertiesToLoad.Add("mail"); searcher.PropertiesToLoad.Add("displayName"); foreach (SearchResult result in searcher.FindAll()) { Console.WriteLine(result.Path); } </code></pre> <p><strong>Limitations:</strong></p> <ul> <li>Both methods don't handle primary group membership</li> <li>ASQ don't work across domain, an exception will be thrown if member from another domain is found. So normally you can only perform this for global groups.</li> </ul>

You date appears to be a string so we need to convert it twice:</p> <pre><code>update b set first = to_char( to_date( my_date, 'yyyy/mm/dd-hh:mi:ss:ff3') ,'yyyy-mm-dd hh:mi:ss' ) </code></pre> <p>Generally, when using dates it's far, far easier to only use <a href="http://psoug.org/reference/date_func.html" rel="nofollow">date functions</a> and the provided <a href="http://ss64.com/ora/syntax-fmt.html" rel="nofollow">formats</a>.</p> <p>As an added point if you have a date, store it as a date. It'll save a world of bother later on.</p>

<p>A regular expression substitution will do it. Look at the gsub() function.</p> <p>This gives you what you want (it removes any instance of '[' or ']'):</p> <pre><code>gsub("\\[|\\]", "", n) </code></pre>

<p>This isn't really an aggregation, it's just a groupwise maximum. <code>ROW_NUMBER</code> is the easiest way to write these queries:</p> <pre><code>;WITH CTE AS ( SELECT Query, CreatedTime, UpdatedTime, &lt;other_columns&gt;, ROW_NUMBER() OVER ( PARTITION BY Query ORDER BY CreatedTime DESC, UpdatedTime DESC ) AS RowNum FROM Somethings WHERE CreatedTime &gt;= '20100101' AND CreatedTime &lt; '20100201' ) SELECT * FROM CTE WHERE RowNum = 1 </code></pre> <p>It's not necessarily the most efficient, but it's reasonably good in most cases. And the nice thing is that you can modify this to do top 2 per group, top 3, etc., and you have complete control over ties.</p> <p>(P.S. I hope you don't actually name the column "Query")</p>

<p>Windows Azure machines are yours for the using so if you want a different time zone, go right ahead and set it.</p> <p>The easiest approach is to create a very simple startup task and use <strong>tzutil</strong>, the Windows Time Zone Utility.

Meteor-Bootstrap jQuery wrong version <p>I do have the following message in the console:</p> <pre><code>Uncaught Error: Bootstrap's JavaScript requires at least jQuery v1.9.1 but less than v3.0.0 </code></pre> <p>In .meteor > version file it says it's <code>jquery@1.11.9</code>.</p> <ul> <li>I did tried to meteor remove and the install again both jquery and boostrap separately.</li> <li>Also tried to manualy change current version in .meteor version file to 1.9.1 first in terminal it says: <br><code>jquery upgraded from 1.9.1 to 1.11.9</code><br> But after server restart the current version is back to 1.11.9</li> </ul> <p>What can be done to retrieve the favor of the javascript gods?</p>

<p>Given the format <code>$ _( int, int )___ .</code> where <code>_</code> is an arbitrary amount of whitespace use </p> <pre><code>int n = 0; int result = scanf("$ (%d,%d ) .%n", &amp;int1, &amp;int2); if ((result != 2) || (n == 0)) { ; // failed, handle error. } </code></pre> <p>Let's break the scanf() format down</p> <p><code>"$"</code> match a <code>'$'</code><br> <code>" "</code> match 0 to unlimited number of whitespace.<br> <code>"("</code> match <code>'('</code><br> <code>"%d"</code> match any amount of leading whitespace, then look for an <code>int</code>, storing in the corresponding <code>int *</code>.<br> <code>","</code> match <code>','</code><br> <code>")"</code> match <code>')'</code><br> <code>"."</code> match <code>'.'</code><br> <code>"%n"</code> Save the number of <code>char</code> parsed so far into the corresponding <code>int *</code>. Acting on this directive does not affect the <code>scanf()</code> result.</p> <p>Liberal use of <code>%n</code> could be intersperse should more specific scanning be require than suggested in this solution.</p>

<p>A couple of things to check.</p> <ul> <li><p>The pyenv tool doesn't install Python with a shared library by default. That could result in problems as mod_wsgi wants a shared library. You need to explicitly tell pyenv to build Python with a shared library.</p></li> <li><p>A home directory on many Linux systems is not readable to other users. When mod_wsgi is being initialised, it is running as the Apache user and will not be able to see inside of the home directory. There isn't an issue when the mod_wsgi module is loaded by Apache as Apache is running as root at that point.</p></li> </ul> <p>There are other issues with your configuration where don't follow best practices, but the above, especially the second item is likely the cause of your problem.</p>

<p>I don't know about such tool. You can write your own generator using database metadata info: <code>Connection.getMetadata()</code></p>

<p>This call </p> <pre><code>scanf_s("%s",msg); </code></pre> <p>is missing the size argument. Change to</p> <pre><code>scanf_s("%s", msg, (unsigned)sizeof msg); </code></pre> <p>You are also doing this</p> <pre><code>for(i=0;msg[i]!=NULL;i++) m[i]=msg[i]; </code></pre> <p>which generates a compiler warning, because <code>NULL</code> is pointer value, not a char value. But its biggest sin is not copying the <code>'\0'</code> string terminator. What do have against <code>strcpy()</code> or even <code>strdup()</code>?</p>

<p>As of NHibernate 2.1, the <a href="http://nhforge.org/blogs/nhibernate/archive/2008/11/09/nh2-1-0-bytecode-providers.aspx" rel="nofollow noreferrer">proxy factory is pluggable</a>. Here are some proxy providers supported:</p> <ul> <li>Castle.DynamicProxy</li> <li>LinFu</li> <li>Spring.NET</li> </ul> <p>So proxying will be actually out of NHibernate's responsibility, and the answer to this question really depends on the selected proxy factory.</p>

<p>You just need to multiply your concepts by your documents:</p> <pre><code>(20(currentConceptCount*currentDocumentCount) * 10(previousTime)) / 100(previousConceptCount*previousDocumentCount) </code></pre>

<p>in project.json you need this dependency</p> <pre><code>"Microsoft.Extensions.Localization": "1.0.0-rc2-final", </code></pre> <p>in Startup.cs in ConfigureServices you need code like this:</p> <pre><code> services.AddLocalization(options =&gt; options.ResourcesPath = "GlobalResources"); services.Configure&lt;RequestLocalizationOptions&gt;(options =&gt; { var supportedCultures = new[] { new CultureInfo("en-US"), new CultureInfo("en"), new CultureInfo("fr-FR"), new CultureInfo("fr"), }; // State what the default culture for your application is.

ncurses and stdin blocking <p>I have <em>stdin</em> in a <code>select()</code> set and I want to take a string from <em>stdin</em> whenever the user types it and hits <kbd>Enter</kbd>.</p> <p>But select is triggering <em>stdin</em> as ready to read before <kbd>Enter</kbd> is hit, and, in rare cases, before anything is typed at all. This hangs my program on <code>getstr()</code> until I hit <kbd>Enter</kbd>.</p> <p>I tried setting <code>nocbreak()</code> and it's perfect really except that nothing gets echoed to the screen so I can't see what I'm typing. And setting <code>echo()</code> doesn't change that.</p> <p>I also tried using <code>timeout(0)</code>, but the results of that was even crazier and didn't work.</p>

Is it possible to caputre the rendering audio session from another process? <p>I am taking my first dives in to the WSASAPI system of windows and I do not know if what I want is even possible with the windows API.</p> <p>I am attempting to write program that will record the sound from various programs and break each in to a separate recorded track/audio file. From the reseacrch I have done I know the unit I need to record is the various <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/dd370796%28v=vs.85%29.aspx" rel="nofollow">audio sessions</a> being rendered to a endpoint, and the normal way of recording is by taking the render endpoint and performing a loopback. However from what I have read so far in the MSDN the only interaction with sessions I can do is through <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/dd368246%28v=vs.85%29.aspx" rel="nofollow">IAudioSessionControl</a> and that does not provide me with a way to get a copy of the stream for the session.</p> <p>Am I missing something that would allow me to do this with the WASAPI (or some other windows API) and get the individual sessions (or individual streams) before they are mixed together to form the endpoint or is this a imposable goal?</p>

<p>Your code gives me the following compiler error, skipping some bits</p> <pre><code>/usr/include/boost/spirit/home/support/action_dispatch.hpp:142:13: error: no matching function for call to ‘action_dispatch&lt;&gt;::do_call( const main()::&lt;lambda(const string&amp;)&gt;&amp;, action_dispatch&lt;&gt;::fwd_tag&lt;std::vector&lt;char&gt;&gt;, ... </code></pre> <p>which boils down to that the argument passed to your lambda is <code>vector&lt;char&gt;</code>, not <code>string</code></p> <p>So, replace <code>string</code> with <code>vector&lt;char&gt;</code>:</p> <pre><code>(+qi::alpha)[[](const std::vector&lt;char&gt;&amp; s) { cout &lt;&lt; std::string(s.begin(), s.end()) &lt;&lt; '\n'; }] </code></pre>

<p>In this particular case, it depends. If using a namespace alias does the trick, by all means prefer it to macros, for all of the usual reasons. But the two do radically different things. You cannot open a namespace using its alias, i.e.: </p> <pre><code>namespace XYZ_ver1 {} namespace XYZ = XYZ_ver1; namespace XYZ { // Illegal! } </code></pre> <p>This works with a macro; in fact, you can define the macro before the namespace has ever appeared. If you need this, then you need to use a macro.</p>

<p>MNagel has the correct link for this, but to reiterate, you want to look at using something like:</p> <pre><code>CREATE PROC dbo.MyProc WITH EXECUTE AS 'SomeUser' AS BEGIN --Proc --Do Stuff END --Proc GO </code></pre> <p>"Execute As" has some other gotchas along the way. You have to allow others to impersonate the specified user and that user would need the appropriate select permissions to the underlying tables.</p> <p>If you want to mass grant permissions, you can do that at the Schema level instead of the object level - something like:</p> <pre><code>GRANT SELECT, EXEC ON Schema::dbo TO MyRole; </code></pre> <p>I've used that before to greatly simplify a lot of grant statements for our roles. We have very few overrides for the more general roles so this helps quite a bit.</p>

<p>You have to remove the line <code>editable: true,</code></p> <p>Here is a working example. use this <code>script tag</code>.</p> <pre><code>&lt;script&gt; $(document).ready(function() { var date = new Date(); var d = date.getDate(); var m = date.getMonth(); var y = date.getFullYear(); var Xmas95 = new Date("25 Dec, 1995 23:15:00"); alert('vidda : '+ Xmas95); $('#calendar').fullCalendar({ header: { left: 'prev,next today', center: 'title', right: 'month,agendaWeek,agendaDay' }, //editable: true, events: [ { title: 'All Day Event', start: '20140210' }, { title: 'Long Event', start: new Date(y, m, d-5), end: new Date(y, m, d-2) } ], dayClick: function(date, allDay, jsEvent, view) { alert('Clicked on the entire day: ' + date); console.log(date); } }); }); &lt;/script&gt; </code></pre> <p>this should work fine.

<p>I have identified a workaround. </p> <p>I'm using a tuple for the constraint and handling it myself in the didApplyConstraints handler. </p> <p>The format for the custom constraint assumes that the range begins at the first value and travels <em>counter clockwise</em> until the second value. It makes no allowances for constraint values above PI or below -PI. This solution also doesn't deal with total ranges greater than 2*PI. </p> <p>Ranges that do not cross the +/- PI boundary are "normal" and can be handled normally.</p> <p>Ranges that DO cross the +/- PI boundary are "goofy" and must be handled as a special case (if possible). </p> <p>A solution to the special case seems impossible unless you are tracking angular velocity with an SKPhysicsBody (or manually). This value is required to identify which boundary the node likely "crossed" and should thus be constrained to.</p> <pre><code>// constraint = (CGFloat(M_PI/2), -CGFloat(M_PI/2)) override func didApplyConstraints() { var r = rotationSprite.zRotation if constraint.0 &lt; constraint.1 { // regular constraint, easy to handle. rotationSprite.zRotation = min(max(r, constraint.0),constraint.1) } else // "goofy" constraint that crosses PI boundary { if r &lt; constraint.0 &amp;&amp; r &gt; constraint.1 { if rotationSprite.physicsBody?.angularVelocity &lt; 0 { // clockwise, crossed first value (so long as absolute angular vel is &lt; 2PI rotationSprite.zRotation = constraint.0 } else if rotationSprite.physicsBody?.angularVelocity &gt; 0 // counter clockwise, crossed second value (so long as absolute angular vel is &lt; 2PI { rotationSprite.zRotation = constraint.1 } else { // If 0 velocity (or no velocity), no way to find out which boundary was crossed. rotationSprite.zRotation = constraint.0 // Probably better to default to closest angle } rotationSprite.physicsBody?.angularVelocity = 0 // Alternately, multiply by a negative restitution factor. } } } </code></pre>

Django edit user profile <p>I'm trying to create an "Edit Profile" form in the fronted.

<p>First, you are checking if the object instance is in the collection, but you are only creating one instance once (outside the while loop). Therefore, when you check if <code>!myPartyGroupList.Contains(partyGroup)</code>, it will return false the first time, so you will add the obj to the collection and then it will return false every time.</p> <p>I would use a Dictionary using an Id property as the Dictionary key.</p> <p>like this:</p> <pre><code>Dictionary &lt;int,PartyGroup&gt; myPartyGroupList = new Dictionary &lt;int,PartyGroup&gt;(); using (AseDataReader reader = command.ExecuteReader()) { while (reader.Read()) { int id=Convert.ToInt32(reader["party_group_id"]); if (!myPartyGroupList.ContainsKey( id )) { PartyGroup partyGroup = new PartyGroup(); partyGroup.PartyGroupID = id; partyGroup.PartyGroupName = reader["party_group_name"].ToString(); partyGroup.PersonList = myPersonList; myPartyGroupList.Add(id, partyGroup); // key, value? check param order here } } } </code></pre>

Metro App reading HTML formatted string <p>I have a metro app and want to bind a <code>&lt;TextBlock&gt;</code> element to a string which contains some HTML formatting elements.

<p>It is a very clear algorithm and seems you got it right.
