No restart is required, hence the reference to "hot".</p> </blockquote> <p>But there are limitations:</p> <blockquote> <p>HCR only works when the class signature does not change; you cannot remove or add fields to existing classes, for instance. However, HCR can be used to change the body of a method.</p> </blockquote> |

17,052,884 | 0 | .net web service to validate LDAP credentials using SSL <p>So I'm new to the whole .net thing here, but basically what I want to do is write a web service that will take a SOAP request with user's name and password and check them against an ldap server to validate that the credentials are right. I've already done this in perl, the code is below, but I'd like to replicate it in .net to get some more exposure to it. I've been poking around with c# since I've done a good amount of java programming and it seems like they are pretty similar, but if it's easier in vb or something else I'm not opposed to that. </p> <p>The main problem I'm having is actually connecting to the server itself.

30,732,228 | 0 | <p>You won't subscribe, you'll just have an observable in your viewmodel that you set to true or false, and the menu item will toggle in response. The disabled member of your menu item will look like this:</p> <pre><code>disabled: function() { return myobservable(); } </code></pre> <p>As James Thorpe commented, you'll want to create a custom binding handler to set up your context menu.</p> <p>It sounds like you're working with several unfamiliar tools. Here is a Fiddle with a minimal example: <a href="http://jsfiddle.net/sv3m7ok8/" rel="nofollow">http://jsfiddle.net/sv3m7ok8/</a></p> <p><strong>Update</strong> It occurred to me that since the context menu doesn't bind to a single element, but uses a selector, it makes more sense to do the binding on the <code>body</code> tag. So an updated example: <a href="http://jsfiddle.net/sv3m7ok8/1/" rel="nofollow">http://jsfiddle.net/sv3m7ok8/1/</a></p> <p><strong>Updated again</strong> I now understand that you are specifically trying to get the menu item to enable/disable while the menu is open (and that it doesn't do that normally). I had to go under the covers to get at the menu item node, and hook up a subscription to set the disabled class on it.</p> <pre><code>init: function (element, data, allbindings, data) { var dynamicDisable = false; $.contextMenu({ selector: '.context-menu-one', callback: function (key, options) { var m = "clicked: " + key; window.console && console.log(m) || alert(m); }, items: { "edit": { name: "Clickable", icon: "edit", disabled: function (opt, key) { if (!dynamicDisable) { var node = key.items.edit.$node[0]; data.disableMenu.subscribe(function (dis) { $(node)[dis ? 'addClass' : 'removeClass']('disabled') }); dynamicDisable = true; } return data.disableMenu(); } } } }); } </code></pre> <p>My fiddle sets an interval to toggle disableMenu.

37,669,466 | 0 | <p>I am not quite sure what your worry is (and maybe you should clarify your question if that answer isn't sufficient), but <code>m[10] += 1;</code> doesn't get translated to <code>m[10] = m[10] + 1;</code> because <code>m</code> is user defined class type and overloaded operators don't get translated by the compiler, ever. For <code>a</code> and <code>b</code> objects with a user defined class type:</p> <ul> <li><code>a+=b</code> doesn't mean <code>a = a + b</code> (unless you make it so) </li> <li><code>a!=b</code> doesn't mean <code>!(a==b)</code> (unless you make it so)</li> </ul> <p>Also, function calls are never duplicated.</p> <p>So <code>m[10] += 1;</code> means call overloaded <code>operator[]</code> once; return type is a reference, so the expression is a lvalue; then apply the builtin operator <code>+=</code> to the lvalue.</p> <p>There is no order of evaluation issue. There isn't even multiple possible orders of evaluation!</p> <p>Also, you need to remember that the <code>std::map<>::operator[]</code> doesn't behave like <code>std::vector<>::operator[]</code> (or <code>std::deque</code>'s), because the <code>map</code> is a completely different abstraction: <code>vector</code> and <code>deque</code> are implementations of the Sequence concept (where position matters), but <code>map</code> is an associative container (where "key" matters, not position): </p> <ul> <li><code>std::vector<>::operator[]</code> takes a numerical index, and doesn't make sense if such index doesn't refer to an element of the vector.</li> <li><code>std::map<>::operator[]</code> takes a key (which can be any type satisfying basic constraints) and <strong>will create a (key,value) pair if none exists</strong>.</li> </ul> <p>Note that for this reason, <strong><code>std::map<>::operator[]</code> is inherently a modifying operation and thus non const</strong>, while <code>std::vector<>::operator[]</code> isn't inherently modifying but can allow modification via the returned reference, and is thus "transitively" const: <code>v[i]</code> will be a modifiable lvalue if <code>v</code> is a non-const vector and a const lvalue if <code>v</code> is a const vector.</p> <p>So no worry, the code has perfectly well defined behavior.</p> |
7,093,864 | 0 | <p>I think I have worked out the issue. The steps follow:</p> <ul> <li>Create an an individual named LoggerRepository on each thread.</li> <li>Set the ThreadContexts property for the log file name.</li> <li>Use the XmlConfiguratior to configure the repository.</li> <li>Use the LogManager to Get the named logger (in the XML configuration file) using the named LoggerRepository for that thread.</li> </ul> <p>In return I get a new configured logger pointing to the respective file for that thread.</p> <p>The XML configuration is the same as it was originally and shown here for completeness:</p> <pre class="lang-xml prettyprint-override"><code><?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <log4net> <logger name="ProductionLogger"> <appender-ref ref="XmlAppender"/> <level value="ALL"/> </logger> <appender name="XmlAppender" type="log4net.Appender.FileAppender"> <file type="log4net.Util.PatternString" value="D:\Temp\Logs\%property{LogName}.log" /> <immediateFlush value="true"/> <appendToFile value="true" /> <layout type="log4net.Layout.SimpleLayout" /> </appender> </log4net> </configuration> </code></pre> <p>The code to create the loggers is below. Each time this code is run it is run in its own thread.</p> <pre><code>ILoggerRepository loggerRepository = LogManager.CreateRepository(logFileName + "Repository"); ThreadContext.Properties["LogName"] = logFileName; log4net.Config.XmlConfigurator.Configure(loggerRepository); ILog logger = LogManager.GetLogger(logFileName + "Repository", "ProductionLogger"); </code></pre> <p>This seems to work with no issues so far.

35,350,853 | 0 | Angular2 - Different views with different template <p>With $stateProvider and abstract property in Angular 1, I could create different views with different template easily.

24,612,466 | 0 | <p>There are different possibilities of implementing a threading system for a virtual machine. The two extreme forms are:</p> <ol> <li><strong>Green threads</strong>: All Java <code>Thread</code> instances are managed within one native OS thread. This can cause problems if a method blocks within a <code>native</code> invocation what makes this implementation complex. In the end, implementers need to introduce <em>renegade threads</em> for holding native locks to overcome such limitations. </li> <li><strong>Native threads</strong>: Each Java <code>Thread</code> instance is backed by a native OS thread.</li> </ol> <p>For the named limitations of green threads, all modern JVM implementations, including HotSpot, choose the later implementation. This implies that the OS needs to reserve some memory for each created thread. Also, there is some runtime overhead for creating such a thread as it needs direct interaction with the underlying OS. At some point, these costs accumulate and the OS refuses the creation of new threads to prevent the stability of your overall system.</p> <p>Threads should therefore be pooled for resue. Object pooling is normally considered bad practice as many programers used it to ease the JVM's garbage collector. This is not longer useful as modern garbage collectors are optimized for handling short-living objects. Today, by pooling objects you might in contrary slow down your system. However, if an object is backed by costly native resources (as a <code>Thread</code>), pooling is still a recommended practice. Look into the <a href="http://docs.oracle.com/javase/8/docs/api/java/util/concurrent/ExecutorService.html" rel="nofollow"><code>ExecutorService</code></a> for a canonical way of pooling threads in Java.</p> <p>In general, consider that context switches of threads are expensive. You should not create a new thread for small tasks, this will slow your application down. Rather make your application less concurrent. You only have a number of cores which can work concurrently in the first place, creating more threads than your (non-virtual) cores will not improve runtime performance. Are you implementing some sort of divide-and-conquer algorithm? Look into Java's <a href="http://docs.oracle.com/javase/8/docs/api/java/util/concurrent/ForkJoinPool.html" rel="nofollow"><code>ForkJoinPool</code></a>.</p> |

33,297,763 | 0 | Force connection reestablishment from client app to GCM <p>We are using GCM for messaging from server to the client app. It is a standard implementation where installation of the client app talks to the gcm server to get the reg id, sends it to our server and our server uses that reg id to push messages to the app. Our requirement is that these push notifications should be instantaneous and as real time as possible.</p> <p>But the connection between GCM and the client app seems to disappear after a few minutes of inactivity. We have tried several things on our end: 1. Using an alarm manager to keep running a heartbeat intent that sends heartbeats to gcm. This does not work on custom android OSes where cleaning memory forces close of all app alarms. 2. Sending an upstream message from client to gcm in the hope that it establishes connection. 3. Using high priority messages from server to gcm hoping that would force a connection between gcm and app.</p> <p>None of it has worked so far.

Hibernate is not for you - yet.</p> <p>Hibernate is an object-relational mapping tool (ORM). It's a technology that lets you associate information in relational database tables to objects in your middle tier. So if you have a PERSON table with columns id, first, and last Hibernate will let you associate those data with the private data members in your Person Java class.</p> <p>That sounds easy, but it gets complicated quickly. Your relational and object models might have one-to-many and many-to-many relationships; Hibernate can help with those. Lazy loading, caching, etc. can be managed by Hibernate. </p> <p>But it comes at a cost. And it can be difficult if you aren't familiar with it.</p> <p>If you have a deadline, I'd recommend creating a Java POJO interface for your persistence classes and doing the first implementation using JDBC. If you want to swap it out for Hibernate later on you can do it without affecting clients, but you'll have a chance of making progress without Hibernate that way.</p> |

Here's a piece of code from the function Perl_do_openn in file doio.c:</p> <pre><code>fd = PerlIO_fileno(IoIFP(io)); if (IoTYPE(io) == IoTYPE_STD) { /* This is a clone of one of STD* handles */ result = 0; } else if (fd >= 0 && fd <= PL_maxsysfd) { /* This is one of the original STD* handles */ saveifp = IoIFP(io); saveofp = IoOFP(io); savetype = IoTYPE(io); savefd = fd; result = 0; } </code></pre> <p>if you open an existing filehandle, the filehandle will be closed and reopened by open(), This doesn't happen with STD* handles, as you can see from the code above. So perl takes the next free handle for opening and the older one remains open.</p> |

19,684,372 | 0 | <p>As far as the compiler is concerned, it doesn't need to know the actual name of the parameter when the function is being declared. All it needs is the signature of the function: the return type, name, and the parameter types. </p> <p>You only need the parameter name when you <em>define</em> the function, i.e. in a source file.</p> <pre><code>// foo.h void foo(const char*); // foo.c #include "foo.h" void foo(const char * c) { //OK } void bar(const char*) { //Indeed, we have no way to access the parameter } </code></pre> <p>As long as these signatures match, everything will work fine. If this is your header file though, it's usually better to include the parameter name in the declaration as it is useful documentation.</p> |
24,845,221 | 0 | How do I define individual pages in Express.js <p>I'm just getting started with <strong>express.js</strong> and am failing to understand how one defines discrete "pages" (in the traditional sense) that one can link to internally.</p> <p>I'm using Jade as a template engine and I see how it pulls the various components together and references them in the app.js (which is what is initially invoked by npm) so that, in effect is my "index". Would be great to see a tutorial on what one does to then build out pageA, pageB, pageC so that they can be linked to via <code><a href="pageA.html"></code> (or the Jade equivalent).</p> <p>I'm assuming this is possible, right?</p> |

22,087,268 | 0 | <blockquote> <p>With Visual C++, <code>new</code> calls the <code>malloc</code> function.</p> </blockquote> <p>This is partially true: the <code>new</code> expressions in your code do call <code>operator new</code> to allocate memory and <code>operator new</code> does indeed call <code>malloc</code>. But the pointer to the initial element that is yielded by the <code>new</code> expression is not necessarily the pointer obtained from <code>malloc</code>.</p> <p>If you dynamically allocate an array of objects that require destruction (like your <code>CTheClassWith_string</code> type), the compiler needs to keep track of how many elements are in the array so that it can destroy them all when you <code>delete</code> the array.</p> <p>To keep track of this, the compiler requests a slightly larger block from <code>malloc</code> then stores some bookkeeping information at the beginning of the block. The <code>new</code> expression then yields a pointer to the initial element of the array, which is offset from the beginning of the block allocated by <code>malloc</code> by the bookkeeping information.</p> |
