5,414,451 | 0 | <p>I can think of some easy things Microsoft could have done to the memory allocator that would have greatly reduced LOH fragmentation without major overhaul, such as rounding allocation sizes up to some multiple like 4K. Given that the smallest non-static LOH objects were 85K, that would represent at most a 5% loss of useful space, but would reduce the number of different-sized objects and gaps. BTW, I'm really unconvinced of the value forcing all big objects to the LOH (as opposed to, perhaps, having a means of designating when an object is created whether it should go to the LOH or not). I can understand some value in separating small objects from big ones once they reach Level 2, but there are enough cases where big objects get created and abandoned that forcing them to level 2 seems counterproductive.</p> |
26,281,319 | 0 | <p><code>DatePart</code> can accept dates which are actually text instead of Date/Time datatype.

26,219,052 | 0 | JHipster Persist Data/Access Database <p>Running with Spring Boot v1.1.7.RELEASE, Spring v4.0.7.RELEASE with hot reloading, etc.</p> <p>Hey JHipsters, I'm working on my first project with JHipster. I can successfully create an application that runs, authenticates, etc. My issues really began when I started to try to create and maintain entities. At this point I've created an entity successfully called "Employees" with all the supporting files that JHipster provides. I've also managed to add the fields that I wanted to that entity (which proved to be more difficult than I originally anticipated), but wasn't able to eliminate the sample fields without creating an error, so I've left them there. </p> <p>Now, maybe I'm missing something here, but when I go and save a group of values in my entity, as soon as I terminate my application, those values evaporate. Is JHipster designed to operate this way in developer mode? If so, how do I persist my values in the MYSQL database that JHipster created for me?</p> <p>Let me know if you need any more information from me to help.</p> |

7,388,567 | 0 | <p>Some responders have suggested storing the data in ViewState. While this is custom in ASP.NET you need to make sure that you absolutely understand the implications if you want to go down that route, as it can really hurt performance. To this end I would recommend reading <a href="http://weblogs.asp.net/infinitiesloop/archive/2006/08/03/Truly-Understanding-Viewstate.aspx" rel="nofollow">TRULY understanding ViewState</a>.</p> <p>Usually, storing datasets retrieved from the database in ViewState really hurts performance. Without knowing the details of your situation I would hazard a guess that you are better off just loading the data from the database on every request. Essentially, you have the option of a) serializing the data and sending the data to the client (who could be on a slow connection) or b) retrieving the data from the database, which is optimized for data retrieval and clever caching. </p> |

18,483,602 | 0 | Tomcat ClientAbortException Listener? <p>Our Tomcat 6 Server is reporting quite a few ClientAbortException errors, which I believe is down to say a user navigating away from the page before its fully loaded. We are also getting No buffer space available (maximum connections reached? errors.</p> <p>Is there a way of creating a ClientAbortException Listener to terminate any Abandoned Connection Clean Up or unused http threads and delete any byte data used for incomplete downloaded images.</p> <p>This project is inherited and I've noticed that even when running locally if I start VisualJVM and view the monitor and then open a website locally I see an Abandoned Connection Clean Up thread created and a number of http threads created. If I open another website on the same local web server I can see yet again another Abandoned Connection Clean Up thread created and another set of http threads created. If I navigate through the pages, I don't see any other connections created, mainly because the project is using database pooling but if I close the browser the threads are still running, they are not being freed up.</p> <p>Needless to say, as soon as the server has been running for a number of days or is under load the aforementioned errors are generated.</p> <p>Any help would be much appreciated :-)</p> |

20,839,539 | 0 | <p>This problem is quite simple to solve even without jQuery or similar in plain JavaScript. Here it is for your example:</p> <pre><code>var next = (function (sections) { function getTop(node) { return node ? node.offsetTop + getTop(node.offsetParent) : 0; } return function () { var i, nodeTop, top = window.pageYOffset; for (i = 0; i < sections.length; i += 1) { nodeTop = getTop(document.getElementById(sections[i])); if (nodeTop > top) { window.scrollTo(window.pageXOffset, nodeTop); return; } } }; }(['top', 'fe1', 'fe2', 'fe3', 'fe4', 'fe5'])); </code></pre> <p>The code is quite general, so you can pass any section ids you want (they just need to appear in the correct order).</p> <p>We use two standard DOM properties/functions here <code>window.pageYOffset</code> and <code>window.scrollTo()</code> to get and set vertical offset of the window (<code>window.pageXOffset</code> is used to keep horizontal offset the same). To get the vertical offset of the section start I defined <code>getTop</code> function using simple recursion (jQuery uses similar code IMHO).</p> <p>Resulting function <code>next()</code> is defined in a self-invoking closure to hide the implementation and helper function. To use it after this code is run, you simply call</p> <pre><code>next(); </code></pre> <p>I tested this code, so I am quite confident it works :).</p> |

24,972,989 | 0 | <p>As mentioned by @SirDarius, this is implementation dependent and therefore you would need to check on a per implementation basis.</p> <p><em>Usually</em>, <code>std::set</code> is implemented as a red-black tree with lean iterators. This means that for each element in the set, there is <em>one node</em>, and this node roughly contains:</p> <ul> <li>3 pointers: 1 for the parent node, 1 for the left-side child and one for the right-side child</li> <li>a tag: red or black</li> <li>the actual user type</li> </ul> <p>The minimal foot-print of such a node on a 64 bits platform is therefore <code>footprint(node)</code>:</p> <ul> <li>3*8 bytes</li> <li><code>sizeof(MyClass)</code>, rounded to 8 bytes (for alignment reasons: look up "struct padding")</li> </ul> <p><em>Note: it is easy to use an unused bit somewhere to stash the red/black flag at no additional cost, for example taking into account the fact that given node alignments the least-significant bits of the pointers are always <code>0</code>, or inserting in <code>MyClass</code> padding if any.</em></p> <p><em>However</em>, when you allocate an object <code>T</code> via <code>new</code> (which is what <code>std::allocator</code> does under the hood, and which itself uses <code>malloc</code> unless overloaded), you do not allocate <em>just</em> <code>sizeof(T)</code> bytes:</p> <ul> <li>a typical implementation of <code>malloc</code> uses <em>size buckets</em>, meaning that if you have 8 bytes buckets and 16 bytes buckets when you allocate a 9 bytes object it goes into a 16 bytes bucket (wasting 7 bytes)</li> <li>furthermore, the implementation also has some overhead to <em>track</em> those allocated blocks of memory (to know not to reuse that memory until it's freed); though minimal, the overhead can be non-negligible</li> <li>finally, the OS itself has some overhead for each page of memory that the program requests; although that is probably negligible</li> </ul> <p>Therefore, indeed, the use of a <code>set</code> will most likely consume <em>more</em> than just <code>set.size() * sizeof(MyClass)</code>, though the overhead depends on your Standard Library implementation. This overhead will likely be large for small objects (such as <code>int32_t</code>: on a 64-bits platform you are looking at least at a +500% overhead) because the cost of linking the nodes together is usually fixed, whereas for large objects it might not be noticeable.</p> <hr> <p>In order to reduce the overhead, you traditionally use <em>arrays</em>. This is what a B-Tree does for example, though it does so at the cost of <em>stability</em> (ie, each element staying at a fixed memory address regardless of what happens to the others).</p> |

This provides more consistent results if the active window's keyboard layout is different to the script's keyboard layout. It also prevents key combinations which don't actually produce the given end characters from ending input; for example, if @ is an end key, on the US layout Shift+2 will trigger it but Ctrl+Shift+2 will not (if the E option is used). If the C option is also used, the end character is case-sensitive.</p> <p>EndKeys A list of zero or more keys, any one of which terminates the Input when pressed (the EndKey itself is not written to OutputVar). When an Input is terminated this way, ErrorLevel is set to the word EndKey followed by a colon and the name of the EndKey. Examples: EndKey:., EndKey:Escape.</p> <p>The EndKey list uses a format similar to the Send command. For example, specifying {Enter}.{Esc} would cause either ENTER, period (.), or ESCAPE to terminate the Input. To use the braces themselves as end keys, specify {{} and/or {}}.</p> <p>To use Control, Alt, or Shift as end-keys, specify the left and/or right version of the key, not the neutral version. For example, specify {LControl}{RControl} rather than {Control}.</p> <p>Although modified keys such as Control-C (^c) are not supported, certain characters that require the shift key to be held down -- namely punctuation marks such as ?!:@&{} -- are supported in v1.0.14+. Other characters are supported with the E option described above, in v1.1.20+.</p> <p>An explicit virtual key code such as {vkFF} may also be specified. This is useful in the rare case where a key has no name and produces no visible character when pressed.

I am using java,servlet, JSP, tomcat 7 as part of the technologies. </p> <p><strong>BackGround:</strong> The reason for URL-Rewriting is that when my browser cookies are disabled the connection between the client and the server is not established and session on being lost and for each request that comes from the browser the server thinks as a new request. </p> <p>By reading through the <a href="https://stackoverflow.com/questions/2065735/how-can-i-do-sessions-in-java-if-some-one-disables-cookies-in-my-browser?lq=1">interne</a>t found that URL-Rewriting is one solution. </p> <p>My application has just one JSP page called <code>root.jsp</code> This is how i am loading the jsp page from my servlet. I have only one servlet that handles all the request.</p> <pre><code>getServletContext().getRequestDispatcher("/view/root.jsp").forward( request, response); </code></pre> <p>In <code>root.jsp</code> includes another jsp pages as a part of <code>root.jsp</code> it shown below. Based on the programming logic the respective JSP page that needs to be included get added.</p> <pre><code><div class="grey_container"> <jsp:include page="${requestScope.jspPage.pageFileUrl}" flush="false" /> </div> </code></pre> <p>I read that the URL-rewriting is possible using <code>HttpServletResponse encodeURL() and encodeRedirectURL()</code>.

35,997,353 | 0 | <p>The cells are reused in iOS, so you need to make sure you properly unhook handlers and reset state when a cell is reused. You can do something like this:</p> <pre><code>public partial class CustomCell : UITableViewCell { EventHandler _likeButtonHandler; public static readonly NSString Key = new NSString (typeof(CustomCell).Name); public static readonly UINib Nib = UINib.FromName (typeof(CustomCell).Name, NSBundle.MainBundle); public CustomCell () { } public CustomCell (IntPtr handle) : base (handle) { } public override void PrepareForReuse () { LikeButton.TouchUpInside -= _likeButtonHandler; _likeButtonHandler = null; base.PrepareForReuse (); } public void SetupCell (int row, string Name, EventHandler likeBtnHandler) { _likeButtonHandler = likeBtnHandler; LikeButton.TouchUpInside += _likeButtonHandler; LikeButton.Tag = row; NameLabel.Text = Name; RowLabel.Text = row.ToString (); } } </code></pre> <p>Notice that I unhook the event handler in the <code>PrepareForReuse</code> override. This is the correct place to do clean up and reset a cell for reuse. You should NOT be using <code>MovedToWindow()</code>.</p> <p>Then your <code>GetCell</code> method will look like this:</p> <pre><code> public override UITableViewCell GetCell (UITableView tableView, NSIndexPath indexPath) { var cell = tableView.DequeueReusableCell (CustomCell.Key) as CustomCell ?? new CustomCell (); cell.SetupCell (indexPath.Row, _fruits [indexPath.Row], _likeButtonHandler); return cell; } </code></pre> <p>The <code>_likeButtonHandler</code> is a simple <code>EventHandler</code>.</p> |
