32,027,651 | 0 | <blockquote> <p>Is Task a specific case where we rely on the native javascript implementation of Task?</p> </blockquote> <p>Exactly. You'll notice that <code>Task</code> the type but not <code>Task</code> the tag (thing on the right) are exported from the module, so you can't actually access the latter. It's a placeholder to make the type system happy.</p> <p>Instead, the Native JavaScript implementation knows what tasks <em>really</em> are, which is <a href="https://github.com/elm-lang/core/blob/2.1.0/src/Native/Task.js#L18-L58" rel="nofollow">a JS object</a>. Any native module dealing with Tasks (either the <code>Task</code> module or any third-party library like <code>elm-http</code>) is in on the secret. However, the <code>Task</code> module exports a good number of helper functions that you can have a lot of control over tasks using only the already published libraries.</p> <p>Clarification Edit: Yes, you need to use a third-party library to get a task that actually does some effect in the outside world. To actually run that task, you need to send it out a port; until you do that a Task is just a <em>description</em> of the work to do.</p> |

12,582,455 | 0 | <p>Have you considered <a href="https://notex.ch" rel="nofollow"><strong>NoTex</strong></a>: It is a UI to Sphinx and uses reStructuredText for content and LaTex for presentational issues (like HTML for structure and CSS for design). It's completely browser based, to you don't have to go through the head ache of installing LaTex/XeTex etc.</p> <p>In my opinion reStructuredText is the successor for the <em>content</em> part of LaTex; but since LaTex is so good in producing publication quality PDFs it should be used for the design part. Of course it would be nice to have an engine that's completely independent of LaTex and that translates rST directly into PDFs. Unfortunately <em>none</em> of those tools produce anything that can reach LaTex in terms of quality. </p> |

9,737,040 | 0 | <p>That book seems to be assuming the compiler inlines at a source level, this of course totally depends on the compiler. Most will begin inlining at the AST level, where transforms and certain optimizations can and will occur. This all assumes the compiler <em>will</em> inline the code.</p> <p>If we look at your function, any <em>decent</em> compiler will turn them both into the same IR code, as it will compile the inline function before it is inlined, thus a temporary is required regardless (at IR level). when the IR is then actually inlined, the temporary will be folded away and instead replaced with the assignment destination of the call to <code>max</code>.</p> <p>When we compile down to machine code, things can change even more, not only can temporaries be removed, but the destination will most likely be a register (in this case), which will have probably been used for on of the source operands as well.</p> <p><strong>Bottom Line:</strong> This totally depends on your compiler, optimization levels and how it does variable livelyness analysis, value propagation and folding. </p> |

27,921,989 | 0 | <p>In almost all cases, font glyphs are composed of <strong>filled shapes</strong>. They don't use the stroke (line). So when your SVGs are being converted to a font, the font SVGs are getting a fill applied, even if they didn't have one before.</p> <p>The differences between browsers is probably explained by the fact that each browser may be loading a different generated font type. Eg. woff vs TTF etc.</p> <p>The fix is to design your SVGs so that they only use filled shapes and <strong>don't</strong> rely on strokes (ie. line colour, width etc). If you follow the following rules, your glyphs should always work when converted:</p> <ol> <li>Keep your line colour as "none" or "transparent",</li> <li>Never use any fill colour except black (ie. don't use "white" to make holes)</li> <li>Never let shapes cross over themselves or other shapes.</li> </ol> <p>So, for example, in the case of your star, it should be designed as a filled star shaped object with a star shaped hole in it.</p> |

34,040,877 | 0 | <p>As Alexander said, if you choose <a href="http://gruntjs.com" rel="nofollow">Grunt</a>, you can use a <a href="https://github.com/gruntjs/grunt-contrib-concat" rel="nofollow">concat plugin</a> to merge a list of selected files into a single destination:</p> <p>after you load the select plugin in your gruntfile.js</p> <pre><code>grunt.loadNpmTasks('grunt-contrib-concat'); </code></pre> <p>define a task in grunt configuration:</p> <pre><code>grunt.initConfig({ concat: { options: { separator: ';', }, dist: { // your source file list src: ['src/js/*.js'], //your destination file dest: 'dist/app.js', }, }, }); </code></pre> <p>then register this task to a list:</p> <pre><code>grunt.registerTask('compile', ['concat']); </code></pre> <p>this would be run by typing "grunt compile" on the command line</p> <p>so you only have to include the dist/app.js file in your index.</p> <p>There are many plugins available in grunt, i.e. you can inculde your app.js file dynamically using the <a href="https://www.npmjs.com/package/grunt-include-source" rel="nofollow">grunt-include-source</a> plugin, or minimize the js files using <a href="https://github.com/gruntjs/grunt-contrib-uglify" rel="nofollow">grunt-contrib-uglify</a>.</p> <p>More information on the gruntfile are available <a href="http://gruntjs.com/sample-gruntfile" rel="nofollow">here</a></p> <p>You can achieve the result as requested in the second point instead, i think you could use solutions like:</p> <ul> <li><a href="https://webpack.github.io/" rel="nofollow">WebPack</a></li> <li><a href="http://requirejs.org/" rel="nofollow">RequireJS</a></li> </ul> <p><strong>UPDATE</strong>:</p> <p>I couldn't find a concat end to end tutorial, I'm sorry.</p> <p>For a generic Grunt tutorial you can read <a href="http://adrianmejia.com/blog/2014/10/07/grunt-js-tutorial-from-beginner-to-ninja/" rel="nofollow">this</a></p> <p>Otherwise you can follow the <a href="http://gruntjs.com/getting-started" rel="nofollow">getting started</a> page from the official Grunt site for installation, configuration and have a general overview.</p> <p>When they talk about plugins please refer to the README of the <a href="https://github.com/gruntjs/grunt-contrib-concat" rel="nofollow">grunt-contrib-concat</a> plugin linked and explained above.</p> <p>Those pages could give you all the skills needed.</p> <p>Finally, customize the concat configuration in Gruntfile.js by putting in <code>dist.src</code> all files to be merged into the file set as <code>dist.dest</code> and only include the latter in your html.</p> <p>Once the set-up is complete, execute your task by typing <code>grunt compile</code> on the command line in your project folder, and the merged file will be produced.</p> |
25,514,233 | 0 | <p>I don't think the loop will be slower. You are accessing the memory of the M1 and M2 arrays in the same way in both instances i.e. . If you want to make the "manual" version faster then use scalar replacement and do the computation on registers e.g.</p> <pre><code> double M1_0 = M1[0]; double M2_0 = M2[0]; result[0] = M1_0*M2_0 + ... </code></pre> <p>but you can use scalar replacement within the loop as well. You can do it if you do blocking and loop unrolling (in fact your triple loop looks like a blocking version of the MMM).</p> <p>What you are trying to do is to speed up the program by improving locality i.e. better use of the memory hierarchy and better locality.</p> |
19,227,018 | 0 | <p>Your regular expression is self-contradictory.</p> <p>You are bounding your pattern on word boundaries, and then including a non-word character in the string you're looking for. Since the '.' character isn't a word character, there will never be any strings that are delimited by word boundaries that include the '.'. </p> <p>Put another way, since the '.' is itself a word boundary, you are looking for [word-boundary][word-boundary][word], which cannot occur.</p> <p>Just take out the word boundaries in your REGEXP:</p> <pre><code>WHERE INET_NTOA(ip) REGEXP '\.111' </code></pre> |
10,759,817 | 0 | <p>You can use <a href="http://p3rl.org/IPC%3a%3aOpen2" rel="nofollow"><code>IPC::Open2</code></a> to attache two file handles, one to the input and one to the output of a program. It may be closer to what you really want to use <a href="http://p3rl.org/IO%3a%3aSocket%3a%3aSSL" rel="nofollow"><code>IO::Socket::SSL</code></a>, which functions like <code>IO::Socket::INET</code> but encrypted.</p> <p><strong>Update:</strong> My best guess is that your doubling up <code>\r</code> characters. According to the man page for <code>s_client</code> <code>-crlf</code> converts line feeds into carriage return + line feed. An when you print to the <code>$sslwrite</code> handle you are sending <code>"\r\n"</code>. I think the result would be that the server would receive "\r\r\n" at the end of each command. You probably want to drop the <code>-crlf</code> from the <code>openssl</code> command in your program.</p> |
37,378,816 | 0 | <p>There is no easy way to do that. Maybe with very complex query, but it will be difficult to maintain and may be even less efficient than doing that with several simpler queries.</p> <p>The solution described by you costs 1 + (number of categories) queries, not two, of course. You could union them easily, and then you would have two queries and less trips do database, but similar load for db (comparing to your solution).</p> <p>Even if you would assume, that there is a way to fetch everything with single query, then db has to do almost the same work (fetch 3 newest posts from every category). So having 2 queries vs 1 hypothetical is not a big penalty in terms of performance. Moreover, I can imagine that DB engine could have some issues with finding most optimal execution plan, especially if you would add there functions etc.</p> <p>And the last solution. There is a way for fetching up to 3 posts from each category, but that require modifying schema and some application-side work. You can add a boolean column "most_recent" and have always 3 posts per cat. with <code>true</code> and false for the rest. You would have to keep updating it every time when you are adding/deleting posts. That is achievable as well with db triggers. Then your problem is trivial to resolve, but only because you have done some precomputation.</p> |

4,601,965 | 0 | <p>Yes, that is the write way.</p> <p>It's just that instead of writing webpart directly, you can write the usercontrol and then host it in a wrapper webpart.</p> <p>The advantage of this approach is that you can have designer for creating UI elements which is available while creating usercontrol. For sharepoint 2007, the wrapper webpart is already available called smart part. To smartpart, you can just give the location of your user control(.ascx) to load.</p> <p>In sharepoint 2010, the smartpart can be built out of the box using Visual Studio 2010.</p> <p><a href="http://smartpart.codeplex.com/" rel="nofollow">http://smartpart.codeplex.com/</a></p> |

I've noticed that in certain locations only, at high zoom levels some of the lines disappear, then reappear as the map is dragged.</p> <p>I've produced a minimal sample app which demonstrates the problem which exhibits itself both on a real device and an emulator (Gingerbread 2.3.3).</p> <p>The complete code is shown below - (the 'transform' methods are necessary in the real app although they don't appear to be in this minimal sample) :</p> <pre><code>public class DemoMap extends Activity implements MapViewConstants { private MapView mapView; private MapController mapController; private MapOverlay mmapOverlay = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.copymain); mapView = (MapView) findViewById(R.id.mapview); mapView.setTileSource(TileSourceFactory.MAPNIK); mapView.setBuiltInZoomControls(true); mapView.setMultiTouchControls(true); mapController = mapView.getController(); mapController.setZoom(17); // Only shows the bug at ceratin lat/lon positions, this is one GeoPoint point2 = new GeoPoint(39191699, -120102561); mapController.setCenter(point2); mmapOverlay = new MapOverlay(this); List<Overlay> listOfOverlays = mapView.getOverlays(); listOfOverlays.add(mmapOverlay); mapView.invalidate(); } public class MapOverlay extends org.osmdroid.views.overlay.Overlay { public MapOverlay(Context ctx) {super(ctx); } private int mVpl;// viewport left, top, right, bottom private int mVpt; private int mVpr; private int mVpb; private MapView mMv = null; // Two routines to transform and scale between viewport and mapview private float transformX(float in, MapView mv) { float out; out = ((mVpr - mVpl) * in) / (mv.getRight() - mv.getLeft()) + mVpl; return out; } private float transformY(float in, MapView mv) { float out; out = ((mVpb - mVpt) * in) / (mv.getBottom() - mv.getTop()) + mVpt; return out; } @Override protected void draw(Canvas pC, MapView mapV, boolean shadow) { if (shadow) return; Paint paint; paint = new Paint(); paint.setColor(Color.RED); paint.setAntiAlias(true); paint.setStyle(Style.STROKE); paint.setStrokeWidth(1); paint.setTextAlign(Paint.Align.LEFT); paint.setTextSize(12); final Rect viewportRect = new Rect(); final Projection projection = mapV.getProjection(); viewportRect.set(projection.getScreenRect()); mVpl = viewportRect.left; mVpt = viewportRect.top; mVpr = viewportRect.right; mVpb = viewportRect.bottom; // draw two lines to split screen into 2x2 quarters // drag the map left and right and the vertical line disappears, // then reappears! It's OK at one less zoom level pC.drawLine(transformX(mapV.getWidth()/2, mapV), transformY(0, mapV), transformX(mapV.getWidth()/2, mapV), transformY(mapV.getHeight(), mapV), paint); pC.drawLine(transformX(0, mapV), transformY(mapV.getHeight()/2, mapV), transformX(mapV.getWidth(), mapV), transformY(mapV.getHeight()/2, mapV), paint); } } } </code></pre> <p>Interestingly if, in my real app, if I do the drawing to an offscreen bitmap, then draw it all in one go at the end of the Overlay's draw, it's OK the lines don't disappear.</p> <p>Any help will be much appreciated.</p> |

8,642,024 | 0 | <p>You could wrap the Thread's <code>Runnable</code> inside another <code>Runnable</code> that would decrement the counter:</p> <pre><code>Thread createThread(final Runnable r) { return new Thread(new Runnable() { @Override public void run() { try { r.run(); } finally { Foo.decrementCounter(); } } }); } </code></pre> <p>The problem with this is if the <code>Runnable r</code> creates multiple instances of Foo. You'd have to somehow track how many instances the thread created. You could do so using a <code>ThreadLocal<Integer></code>, and then call <code>decrementCounter()</code>, in the <code>finally</code> block, the appropriate number of times. See below for a complete, working example.</p> <p>If you can avoid it, you should not rely on the behavior of the GC as it is quite impredictable! If you insist into dealing with the Garbage Collector, then you should use reference queues -- and to use it properly, you should study the concept of <em>object reachability</em>: <a href="http://docs.oracle.com/javase/7/docs/api/index.html?java/lang/ref/package-summary.html" rel="nofollow">http://docs.oracle.com/javase/7/docs/api/index.html?java/lang/ref/package-summary.html</a></p> <p>As a final note, if I were interviewing you, I'd try to make you realize that the code you propose does not perfectly satisfy the requirements: you'd have to make the class <code>final</code>, or the method <code>incrementCount()</code> <code>final</code> or <code>private</code>. Or, easier, you could increment the count in an instance initializer block: no need to think about methods being overriden in subclasses or newly added constructors not incrementing the count.</p> <hr> <p>A complete example:</p> <pre><code>public class Foo { private static final AtomicInteger liveInstances = new AtomicInteger(0); private static final ThreadLocal<Integer> threadLocalLiveInstances = new ThreadLocal<Integer>() { @Override protected Integer initialValue() { return 0; } } // instance initializer (so you won't have problems with multiple constructors or virtual methods called from them): { liveInstances.incrementAndGet(); threadLocalLiveInstances.set(threadLocalLiveInstances.get() + 1); } public static int getTotalLiveInstances() { return liveInstances.get(); } public static int getThreadLocalLiveInstances() { return threadLocalLiveInstances.get(); } public static void decrementInstanceCount() { threadLocalLiveInstances.set(threadLocalLiveInstances.get() - 1); liveInstaces.decrementAndGet(); } // ... rest of the code of the class ... } class FooCountingThreadFactory implements ThreadFactory { public Thread newThread(final Runnable r) { return new Thread(new Runnable() { @Override public void run() { try { r.run(); } finally { while (Foo.getThreadLocalLiveInstances() > 0) { Foo.decrementInstanceCount(); } } } }); } } </code></pre> <p>This way, you can feed this ThreadFactory to a thread pool, for example, or you can use it yourself when you want to build a thread: <code>(new FooCountingThreadFactory()).newThread(job);</code></p> <p>Anyways, there's still a problem with this approach: if a thread creates instances of <code>Foo</code> and stores them on global scope (read: <code>static</code> fields), then these instances will still be alive after the thread has died, and the counter will all the same be decremented to 0.</p> |

36,702,631 | 0 | <p>A few recommendations I would like to make (based on the app we've built which also uses Table Storage exclusively).</p> <ul> <li>Introduce a new entity called <code>Account</code> or <code>Subscription</code>. You can use a GUID to uniquely identify an account.</li> <li>Along with user information (user id, password etc.) in the user's table, store the account information as well. So at all times when you're authenticating a user, you're making point queries. Also store the user's role (Member or Owner) in the user's table. Doing this way, you would know if the user is an individual user or part of a team. If the user is part of a team, then what the role of that user in that team (Owner or Member).</li> <li>Store 2 copies of user data. First copy is what you're using now. Second copy essentially associate a user with an account where the PartitionKey of the second copy is the account id and row key is the PartitionKey of the first copy. This will help you find the users in a particular team.</li> </ul> <p><strong>Individual User Login Scenario</strong></p> <p>So an individual user logs in using their username/password. You retrieve the information about the user and there you find out that the user is an individual user based on the account type.</p> <p><strong>Team Owner Login Scenario</strong> So when a team owner logs in, based on the login you will find out that the user is a team owner. If the team owner needs to find the list of all the users in the team, you do another query (it will be the PartitionKey query only) which will give you information about all the users in the team.</p> <p><strong>Team User Login Scenario</strong></p> <p>So when a team user logs in, based on the login you will find out that the user is a team user. Since the user is a team user, he/she need not query the table to find out about other users in the team. Even if they do, you will do another query (same as team owner query) to get the list of users in a team.</p> |
254,416 | 0 | <p>An EXISTS operator might be faster than the subquery:</p> <pre><code>SELECT t1.Index, MIN(t1.[Date]), MAX(t1.[Date]) FROM myTable t1 WHERE EXISTS (SELECT * FROM myTable t2 WHERE t2.Index = t1.Index AND t2.[Date] >= '1/1/2000' AND t2.[Date] < '1/1/2001') GROUP BY t1.Index </code></pre> <p>It would depend on table size and indexing I suppose. I like G Mastros HAVING clause solution too.</p> <p>Another important note... if your date is actually a DATETIME and there is a time component in any of your dates (either now or in the future) you could potentially miss some results if an index had a date of 12/31/2000 with any sort of time besides midnight. Just something to keep in mind. You could alternatively use YEAR([Date]) = 2000 (assuming MS SQL Server here). I don't know if the DB would be smart enough to use an index on the date column if you did that though.</p> <p>EDIT: Added GROUP BY and changed date logic thanks to the comment</p> |

The syntax is red when I open the file, turns normal when I make an edit, then turns red again after a save:</p> <p><a href="https://i.stack.imgur.com/QciBg.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QciBg.gif" alt="ReSharper CSHTML error"></a></p> <p>Even when red, the code builds successfully and ReSharper even gives correct information about the syntax on hover:</p> <p><a href="https://i.stack.imgur.com/nG6OU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nG6OU.png" alt="enter image description here"></a> </p> <p>My environment is:</p> <ul> <li>ReSharper 10.0.2</li> <li>Visual Studio Enterprise 2015 Update 1</li> <li>ASP.NET 4.5</li> <li>MVC 5</li> </ul> <p>I have tried the solutions offered in other questions (e.g. <a href="http://stackoverflow.com/questions/15713167/resharper-can-not-resolve-symbol-even-when-project-builds">Resharper "can not resolve symbol" even when project builds</a>, <a href="http://stackoverflow.com/questions/29898607/resharper-is-suddenly-showing-red-for-razor-syntax">Resharper is suddenly showing red for Razor syntax</a>) like Suspending/Resuming ReSharper, clearing caches, etc. I even tried reinstalling ReSharper entirely but none of that helped.</p> <p>Potentially relevant (?) is that I recently installed MVC 3 and MVC 4 for other projects, but I have since uninstalled them again.</p> <p>Any suggestions for what might be causing this? Could it be a ReSharper bug somehow?</p> <p><strong>UPDATE:</strong></p> <p>This actually only happends when a ReSharper code cleanup is run and then a save is made.
