12,084,622 | 0 | <p>"Really only useful" is a little subjective, don't you think? If you're asking about whether it's more important to pre-compile templates used server-side as opposed to client-side, it usually is, simply because a server is going to have to render them potentially several thousand times a second so it's wasteful to have to compile them each time they're rendered.</p> <p>In a client-side app, the main concern is whether there's any user-noticeable slowdown associated with rendering templates. There usually isn't, and if there is, generally only a few (maybe partial templates used to build large list views) are responsible. So in most client-side apps, pre-compiling templates is a form of premature optimization.</p> |

13,233,222 | 0 | <p>In the wording in which you've posed the problem, the only correct solution is a double iteration over A and B and filter, as you've suggested. That's because you've stated the problem as to "construct the set C", which lacking other information, generally means to <em>enumerate</em> the set C. The only way to do that and get the exact enumeration of C, at least with the information provided, is to evaluate F on each element in A × B.</p> <p>In another way of interpreting the problem, you can say you have a definition of C if you have a characteristic function, but that's just F. So I'll assume that's not what you mean.</p> <p>The key seems to be that you need to elucidate the relevant properties of F, since that's the algorithmic hook for an enumeration of C. What I mean by this is that you should propose an axiom about F that allows you some shortcut over direct filtration. That could mean, for example, the existence of some auxiliary function G that allows a shorter algorithm. Assuming such a G, an enumeration algorithm would evaluate both F and G, rather than F alone.</p> |

13,031,158 | 0 | Unwanted left margin when using -webkit-transform: scale(...) <p>I am using wkhtmltopdf (which uses the Webkit rendering engine) to convert HTML files to PDF documents. The generated PDFs are A4. In other words, they have fixed dimensions, and thus a limited width.</p> <p>One of the tables in my PDF contains images, which are intricately pieced together in a puzzle-like fashion, and which sometimes take up a lot of room.</p> <p>To fit the resulting puzzle in the constraints of an A4 PDF, I am applying the CSS property -webkit-transform: scale(...);</p> <p>This scales the puzzle beautifully, and it is still clearly legible, but for some reason it also pushes the table containing the puzzle to the right. It seems to be adding a significant margin to the left of the puzzle table, despite my explicitly setting its left margin to 0.</p> <p>Interestingly enough, the smaller the scale in my webkit transformation, the bigger the margin on the left. So for example, if I use scale(0.75) the resulting left margin is around 200 pixels. If I use scale(0.5) the resulting left margin is around 400 pixels.</p> <p>I've tried aligning the puzzle table to the left using absolute, fixed and relative positioning with left: 0. I've also tried floating it to the left, as well as sticking it in a container with text-align set to left.

32,237,671 | 0 | <p>I thought so (the <strong>32 bit</strong> part). You're running into a problem generated by <a href="https://msdn.microsoft.com/en-us/library/windows/desktop/aa384253(v=vs.85).aspx" rel="nofollow">Registry redirection</a>.</p> <p>In other words (on 64bit <em>Windows</em>), for some registry keys (this one included) there are 2 separate locations: one for 64bit(default and old one) and other for 32bit(a new location). By default a 64bit app automatically uses the 64bit registry location; same thing for 32 bit (of course that can be programmatically modified - at least for 64bit apps). </p> <p>So, in order for 32bit apps that have some registry keys hardcoded to still work on 64bit <em>Windows</em> (remember the key hardcoded in the 32bit app is now 64 bit, and it's <em>invisible</em> to the app, while the <em>real</em> 32bit is someplace else), <em>Microsoft</em> came up with this approach. Same approach applies to paths on the filesystem (<em><strong>System32</strong></em> vs <em><strong>SysWOW64</strong></em> under <em>C:\Windows</em>).</p> <p>Now why does it work from cmdline? Being a 64bit OS, the default <em>cmd</em> is 64 bit (which launches the 64bit <em>reg.exe</em>), so it finds the key. Yes you have 2 <em>cmd</em>s (one under each of the above folders), actually (almost) all the <em>Windows</em> executables and dlls are <em>duplicated</em>.</p> <p>To test, start <em>cmd.exe</em> from <em>C:\Windows\SysWOW64</em>, and run the <em>reg</em> command and it will fail.</p> <p>Finally, to get past this, associate <em>.py</em> files (I noticed that you ran it directly) with a 64bit <em>Python</em> version (you might have to download and install it).</p> |

4,829,249 | 0 | <p>i think i read somewhere that it is more difficult to add table rows to an existing table. it had something to do with some browsers adding a tbody tag for you and other browsers not liking a tr tag that doesn't have a table tag wrapped around it (ie).</p> <p>if possible, you could convert your table to divs (or possibly lis) then i think you could get around this issue. i think jQueryUI's draggable has this limitation, not sure.</p> <p>if moving away from tables is not possible, you can probably hide the row, then instantaneously move the row to position, and create a div that looks just like it and move that around, then after the animation you kill the animation div and show the new row.</p> <p>hth</p> |

Instead of 7 INSERT calls to the database per custom post, I end up with 2 making a gynormous difference when attempting to process multiple custom fields while iterating over a large number of posts - in my case now, 20k entries are processed to completion within 15-20min (vs a situation where I would experience a dropout after ~17k posts and a few hrs of processing time)...</p> <p>So the key thing I learned from this whole experience, </p> <p>mind your database calls - they can quickly add up!</p> |

20,279,340 | 0 | <p>Let's start from the beginning. Since <code>fs</code> is a <code>List[Future[T]]</code>, you know <code>x</code> is a <code>Future[T]</code>.</p> <p>You need to register a callback that will fire when the result of <code>x</code> becomes available. The easy way to do this is with <code>onComplete</code>, which takes a function of type <code>Try[T] => U</code>. </p> <p>So the underscore is a <code>Try[T]</code>, which holds the result of <code>x</code>, the <code>Future[T]</code>. There are two possible results for a <code>Future</code>: <code>Success[T]</code>, when the <code>Future[T]</code> worked and holds a result, and <code>Failure[T]</code>, which holds an exception because the <code>Future[T]</code> didn't work. </p> <p>So <code>Try</code> is similar to <code>Option</code>, a way to safely represent an outcome.</p> <p>Hope that helps.</p> |

12,763,310 | 0 | <p>It seems, that your problem has indeed to do with UTF-8. I analyzed your example pages with firebug, and it revealed, that the html pages contain the <strong>UTF-8 BOM-header</strong>, but the untranslated page contains it twice!</p> <p>These 3 characters ( ) at the begin of the file are written by your editor, but they won't be displayed. With a HEX-editor you can see the difference, you can also go to the file properties and look at the file size, you will notice that they differ slightly.</p> <p>My recommendation would be, to save the files as UTF-8 <strong>without</strong> BOM-header. Especially the double header makes the IE to switch to the quirks-mode (you can press <code>F12</code> to get the developer tools in IE to see it), and that causes the different rendering.

16,197,555 | 0 | Keeping std::map balanced when using an object as key <p>I am writing some code where I am storing lots of objects that I want to get back based on set criteria. So to me it made sense to use a map with an object as a key. Where the object would contain the "set criteria".</p> <p>Here is a simplified example of the kind of objects i am dealing with:</p> <pre><code> class key { int x,y,w,h; } class object { ... } std::map<key, object, KeyCompare> m_mapOfObjects; </code></pre> <p>Quite simple, the first thought was to create a compare functions like this:</p> <pre><code> struct KeyCompare { bool operator()(const key &a, const key &b) { return a.x < b.x || a.y < b.y || a.w < b.w || a.h < b.h; } } </code></pre> <p>but then i thought the chances of this returning true are quite high. So I figured this would lead to a very unbalanced tree and therefore slow searching. </p> <p>My main worry is that as I understand it, std::map uses that one function in this way: if( keyCompare(a,b) ) { //left side } else if (keyCompare(b,a)) { //right side } else { //equal } So i can't just use a.x < b.x, because then anything with the same x would be considered equal, which is not what i want. I would not mind it ordering it in this way but its the "equal" bit i just can't seem to solve without making it unbalanced. </p> <p>I figure multiplying them all together is a no no for obvious reasons.</p> <p>So the only solution i could come up with was to create a "UID" base on the info:</p> <pre><code> typedef long unsigned int UIDType; class key { private: UIDType combine(const UIDType a, const UIDType b) { UIDType times = 1; while (times <= b) times *= 10; return (a*times) + b; } void AddToUID(UIDType number) { if(number < m_UID) { m_UID = combine(number, m_UID); } else { m_UID = combine(m_UID, number); } } UIDType UID; public: int x,y,w,h; key() { AddToUID(x); AddToUID(y); AddToUID(w); AddToUID(h); } } struct KeyCompare { bool operator()(const key &a, const key &b) { return a.UID < b.UID; } } </code></pre> <p>But not only does that feel a little hacky, "long unsigned int" isn't big enough to hold the potential numbers. I <em>could</em> put it in a string, but speed is an issue here and I assumed an std::string < is expensive. Overall though the smaller i can make this object the better. </p> <p>I was wondering if anyone has any suggestions for how to do this better. Perhaps i need to use something other then a std::map or perhaps there is another overload. Or perhaps there is something glaringly obvious that i'm missing here. I really feel like i'm over-complicating this, perhaps im really barking up the wrong tree with a map. </p> <p>As i was writing this it occurs to me that divide is another way to get a "unique" number but that could also equal very large numbers</p> |

36,267,484 | 0 | <p>My guess is that you're experiencing a compiler bug. The <code>format</code> keyword, as any other keyword declared with <code>BOOST_PARAMETER_KEYWORD</code> from <a href="http://www.boost.org/doc/libs/1_60_0/libs/parameter/doc/html/index.html" rel="nofollow">Boost.Parameter</a>, is indeed a constant reference. However, there is a const-qualified assignment operator in <code>boost::parameter::keyword</code>, which should be picked by the compiler.</p> <p>As a workaround, you can try replacing the keyword with a call to <code>get</code> static function like this:</p> <pre><code>// Replace this: keywords::format = "%Timestamp% %Message%" // with this: boost::parameter::keyword<keywords::tag::format>::get() = "%Timestamp% %Message%" </code></pre> <p>Also, please note that the attribute names are case sensitive, and the <code>add_common_attributes</code> function adds a "TimeStamp" attribute, not "Timestamp" (note the upper-case S).</p> |

10,217,013 | 0 | <p>You are probably talking of a borderless <code>NSWindow</code> (<code>NSBorderlessWindowMask</code>), with an opaque background view whose alpha is set to zero and an <code>NSProgressIndicator</code> subview to show the progress. You also probably want to use the <code>-[NSWindow center]</code> method to nicely center your window.</p> <p>However, I doubt that you want that kind of UI. A progress bar is probably not visible on top of all desktops, and thus aesthetically worthless.</p> <p>I think a rounded, half-transparant black window will be more suited in your case.

25,719,276 | 0 | <p>The first useful clue is the result of running both commands in the REPL:</p> <pre><code>>>> f = open("asdf.txt","r") >>> f.close <built-in method close of file object at 0x7f38a1da84b0> >>> f.close() >>> </code></pre> <p>So <code>f.close</code> itself returns a method, that you can then call. For example, you could write:</p> <pre><code>>>> x = f.close >>> x() </code></pre> <p>To close the file.</p> <p>So just typing <code>f.close</code> isn't actually enough, as it only returns a method that <em>allows you</em> to close the file. I can even prove this: go make a file and call it <code>example.txt</code>.</p> <p>Then try out the following code:</p> <pre><code>Type "help", "copyright", "credits" or "license" for more information. >>> f = open("example.txt","r") >>> f.close <built-in method close of file object at 0x7f3d411154b0> >>> f.readlines() ['this is an example\n', 'file\n'] </code></pre> <p>So if we just write <code>f.close</code>, we can still use <code>f.readlines()</code>: this is proof that the file isn't actually "closed" to access yet!</p> <p>On the other hand, if we use <code>f.close()</code>:</p> <pre><code>Type "help", "copyright", "credits" or "license" for more information. >>> f = open("example.txt","r") >>> f.close() >>> f.readlines() Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: I/O operation on closed file >>> </code></pre> <p>So that's proof of the previous assertions: <code>f.close()</code> and <code>f.close</code> do in fact <strong>not</strong> do the same things. <code>f.close()</code> actually closes the file, whereas <code>f.close</code> just returns a method to close the file.</p> <hr> <p>In this answer, I used Python 2.7.4. I don't know if the behavior of <code>f.close()</code> and <code>f.close</code> is any different in Python 3+. </p> |
6,761,085 | 0 | <p>Your regex works. There are no spaces left at the end of the line after you run it. </p> <p>What you probably see is the "residual" incremental highlighting that would go away if you used<br> <code>:%s/[ ]\+$//g</code>. — Note the <code>\+</code> instead of the <code>*</code>. the incremental highlighting remains because <code>*</code> <em>always</em> matches, even with zero spaces.</p> <p>To remove the highlighting, type <code>:noh</code> (short for <code>:nohlsearch</code>).</p> <p>FYI: <code>:%s/[ ]*$//g</code> is equivalent to <code>:%s/ *$//g</code>.</p> |

27,813,520 | 0 | <p>Probably a bit late but I had the same problem and found that this can be avoided if you use a different Connection Mode when connecting to a remote Queue. By default the <code>MQConnectionFactory</code> uses <code>WMQ_CM_BINDINGS</code> as it's connection mode. If you change it to <code>WMQ_CM_CLIENT</code> (or whichever connection mode you like that doesn't require native libraries) you should be fine. </p> <pre><code>@Test public void testMQConnectionMode() throws JMSException { MQConnectionFactory cf = new MQConnectionFactory(); assertThat(cf.getIntProperty(CommonConstants.WMQ_CONNECTION_MODE), is(equalTo(CommonConstants.WMQ_CM_BINDINGS))); cf.setIntProperty(CommonConstants.WMQ_CONNECTION_MODE, CommonConstants.WMQ_CM_CLIENT); assertThat(cf.getIntProperty(CommonConstants.WMQ_CONNECTION_MODE), is(equalTo(CommonConstants.WMQ_CM_CLIENT))); } </code></pre> |

33,090,032 | 0 | How can I transform an image for Apple Watch? <p>This question is mentioned in explaining <a href="http://stackoverflow.com/questions/33089008/how-can-i-get-a-glance-interface-controller-blank-slate-for-apple-watch">How can I get a [Glance] Interface Controller / blank slate for Apple Watch?</a> , but is a separate basic question.</p> <p>In iOS, if you have a <code>UIImage</code>, you can create a <code>UIImageView</code> which supports, among other things, rotation, translation, and other transforms. In the Swift that I've seen, you can create a <code>WKInterfaceImage</code>, for instance:</p> <pre><code>@IBOutlet var foo: WKInterfaceImage! </code></pre> <p>However, there were no search results matching, for example <code>WKInterfaceImageView</code>.</p> <p>How can I accomplish the work on an Apple Watch that might be done on an iPhone by getting a <code>UIImageView</code> from an <code>Image</code>? Are old-fashioned <code>UIImageView</code>/<code>UIImage</code>s still available? Or is the best available method something like computing an image on the iPhone and dynamically offering it to the watch?</p> <p>Thanks,</p> |

5,838,508 | 0 | <p>The problem is likely to be at the 2nd <code>cur = cur->next;</code>, which follows the <code>while</code> loop - at that point the loop has guaranteed that <code>cur == NULL</code>.</p> <p>I'm not sure what you're trying to do in that function (has some code been elided for the example?), so don't really have a suggesting at the moment.</p> <p>Also, as your compiler warnings indicate, nothing is being returned by the function even though it's declared to do so. I would have assumed again that this is because something is removed for the purposes of the example in the question, but then again your compiler is complaining as well. Any caller that uses whatever the function is supposed to return is in for a surprise. That surprise may also be a segfault.</p> |
