  • Javascript: Inline function vs predefined functions

    - by glaz666
    Can any body throw me some arguments for using inline functions against passing predefined function name to some handler. I.e. which is better: (function(){ setTimeout(function(){ /*some code here*/ }, 5); })(); versus (function(){ function invokeMe() { /*code*/ } setTimeout(invokeMe, 5); })(); Strange question, but we are almost fighting in the team about this

    How can i use order_by like order_by('field1'*'field2') For example i have items with price listed in different currencies, so to order items - i have to make currency conversion. class Currency(models.Model): code = models.CharField(max_length=3, primary_key=True) rateToUSD = models.DecimalField(max_digits=20,decimal_places=10) class Item(models.Model): priceRT = models.DecimalField(max_digits=15, decimal_places=2, default=0) cur = models.ForeignKey(Currency) I would like to have something like: Item.objects.all().order_by(F('priceRT')*F('cur__rateToUSD')) But unfortunately it doesnt work, i also faild with annotate.

  • What are the limitations of a STA thread in compare to MTA threads ?

    - by Xaqron
    If we make a thread STA like this: Thread.SetApartmentState(STA); then it cannot run code marked with [MTAThread] attribute. We have seen [STAThread] in windows and console applications but I have never seen code with [MTAThread] attribute and don't know which .NET libraries use this attribute. My question is what are the limitations of a thread with apartment state set to STA, in compare to threads with MTA apartment state (natural .NET threads) ?

  • Plugin architecture in .net: unloading

    - by henchman
    Hello everybody, I need to implement a plugin architecture within c#/.net in order to load custom user defined actions data type handling code for a custom data grid / conversion / ... from non-static linked assembly files. Because the application has to handle many custom user defined actions, Iam in need for unloading them once executed in order to reduce memory usage. I found several good articles about plugin architectures, eg: ExtensionManager PluginArchitecture ... but none of them gave me enough sausage for properly unloading an assembly. As the program is to be distributed and the user defined actions are (as the name states) user defined: how to i prevent the assembly from executing malicious code (eg. closing my progra, deleting files)? Are there any other pitfalls one of you has encountered?

  • What is the fastest way to display an image in QT on X11 without OpenGL?

    - by msh
    I need to display a raw image in a QT widget. I'm running X11 on a framebuffer, so OpenGL is not available. Both the image and the framebuffer are in the same format - RGB565, but I can change it to any other format if needed. I don't need blending or scaling. I just need to display pixels as is. I'm using QPainter::drawImage, but it converts QImage to QPixmap and this conversion seems to be very slow. Also it is backed by Xrender and I think there is unnecessary overhead required to support blending in Xrender which I don't really need Is there any better way? If it is not available in QT, I can use Xlib or any other library or protocol. I can modify the driver, X server or anything else.

  • Debugging MEF running in ASP.NET

    - by Jeffrey Lott
    I'm trying to do a proof of concept app for my work using ASP.NET WebForms and the Managed Extensibility Framework. I've got things up and running(ish), but I can't seem to figure out how to attach the instance of Visual Studio that has the MEF code in it to the instance of Visual Studio that is running the Web App. How can I attach my MEF code to the running process so that it hits my breakpoints?

    - by steven.yang
    I want to test whether a function invokes other functions properly with minitest Ruby, but I cannot find a proper assert to test from the doc. The source code class SomeClass def invoke_function(name) name == "right" ? right () : wrong () end def right #... end def wrong #... end end The test code: describe SomeClass do it "should invoke right function" do # assert right() is called end it "should invoke other function" do # assert wrong() is called end end

  • CLOSE_WAIT sockets burst - perhaps because of iptables settings?

    - by Fabrizio Giudici
    I have an Ubuntu 12.04 server virtual box where basically the installed software and configuration are the default ones, plus the installation of a jetty 6 server which servers a few websites. To keep things simple I didn't install apache httpd and used iptables for exposing jetty (which runs on the 8080 port) to the port 80. These are the results of /sbin/iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere localhost tcp dpt:http redir ports 8080 REDIRECT tcp -- anywhere Ubuntu-1104-natty-64-minimal tcp dpt:http redir ports 8080 Chain INPUT (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere localhost tcp dpt:http redir ports 8080 REDIRECT tcp -- anywhere Ubuntu-1104-natty-64-minimal tcp dpt:http redir ports 8080 Chain POSTROUTING (policy ACCEPT) target prot opt source destination I must confess I have a shallow comprehension of how iptables works, in particular for the different kind of chains. This thing works, but sometimes I have an explosion of sockets that stay permanently in CLOSE_WAIT state. I know about what this state means, but since I didn't write the code that manages servlets (they are handled by jetty) I can't fix the problem by patching my code. Eventually the amount of CLOSE_WAIT sockets builds up and makes the server not responsive, so I have to restart jetty. I've looked around for similar problems wth CLOSE_WAIT, and only found cases related to the programmer's code, or problems with Tomcat, not Jetty. I was wondering whether they could be related to a partially broken iptables configuration (the alternative is a bug in Jetty 6, but I first want to exclude other possible causes). Thanks.

  • WLI domain with 3 servers - issues on JPD process startup

    - by XpiritO
    Hi there. I'm currently working on a clustered WLI environment which comprehends 3 servers: 1 admin server ("AdminServer") and 2 managed servers ("mn1" and "mn2") grouped as a cluster, as follows: Architecture diagram: http://img72.imageshack.us/img72/4112/clusterdiagram.jpg I've developed a JPD process to execute some scheduled tasks, invoked using a Message Broker. I've deployed this project into a single-server WLI domain (with AdminServer only) and it works as expected: the JPD process is invoked (I've configured a Timer Event Generator instance to start it up). Message broker: http://img532.imageshack.us/img532/1443/wlimessagebroker.jpg Timer event generator: http://img408.imageshack.us/img408/7358/wlitimereventgenerator.jpg In order to achieve fail-over and load-balancing capabilities, I'm currently trying to deploy this JPD process into this clustered WLI environment. Although, I'm having some issues with this, as I cannot get it to work properly, even if it still works. Here is a screenshot of the "WLI Process Instance Monitor" (with AdminServer and mn1 instances up and running): http://img710.imageshack.us/img710/8477/wliprocessinstancemonit.jpg According to this screen the process seems to be running, as it shows in this instance monitor screen. However, I don't see any output coming out neither at AdminServer console or mn1 console. In single-server domain it was visible output from JPD process "timeout" callback method, wich implementation is shown below: @com.bea.wli.control.broker.MessageBroker.StaticSubscription(xquery = "", filterValueMatch = "", channelName = "/SamplePrefix/Samples/SampleStringChannel", messageBody = "{x0}") public void subscription(java.lang.String x0) { String toReturn=""; try { Context myCtx = new InitialContext(); MBeanHome mbeanHome = (MBeanHome)myCtx.lookup("weblogic.management.home.localhome"); toReturn=mbeanHome.getMBeanServer().getServerName(); System.out.println("**** executed at **** " + System.currentTimeMillis() + " by: " + toReturn); } catch (Exception e) { System.out.println("Exception!"); e.printStackTrace(); } } (...) @org.apache.beehive.controls.api.events.EventHandler(field = "myT", eventSet = com.bea.control.WliTimerControl.Callback.class, eventName = "onTimeout") public void myT_onTimeout(long time, java.io.Serializable data) { // #START: CODE GENERATED - PROTECTED SECTION - you can safely add code above this comment in this method. #// // input transform System.out.println("**** published at **** " + System.currentTimeMillis()); publishControl.publish("aaaa"); // parameter assignment // #END : CODE GENERATED - PROTECTED SECTION - you can safely add code below this comment in this method. #// } and here is the output visible at "AdminServer" console in single-server domain testing: **** published at **** 1273238090713 **** executed at **** 1273238132123 by: AdminServer **** published at **** 1273238152462 **** executed at **** 1273238152562 by: AdminServer (...) What may be wrong with my clustered configuration? Am I missing something to accomplish clustered deployment? Thanks in advance for your help.

  • Nhibernate: mapping two different properties between the same 2 entities

    - by Carlos Decas
    I have a Class A: public class ClassA { public int ID {get; private set;} public string Code {get; private set;} public ClassB B {get; private set;} public IList<ClassB> ListB {get; private set;} } And a ClassB: public class ClassB { public int ID {get; private set;} public string Code {get; private set;} public ClassA A {get; private set;} //some other attributes... } And the Mappings: public ClassAMap() { Table("ClassA"); Id(classA => classA .ID, "ID").GeneratedBy.Identity(); Map(classA => classA.Code, "Code").Unique().Not.Nullable(); //HERE IS THE PROBLEM: -------- References(classA => classA.B,"IDClassB").Cascade.SaveUpdate(); //----- HasMany(classA => classA.ListB).Table("ClassB").KeyColumn("IDClassA").AsBag().Not.LazyLoad().Inverse().Cascade.AllDeleteOrphan(); } ClassB Mappings: public ClassBMap() { Table("ClassB"); Id(classB => classB.ID).GeneratedBy.Identity(); References(classB => classB.A, "IDClassA").ForeignKey("ID").Cascade.SaveUpdate(); } The mappings for ListB in classA worked ok, because at first the was only ListB property and not B, when i had to map B i tried this: References(classA => classA.B,"IDClassB"); The mapping test failed because B wasn't saved, so i did this: References(classA => classA.B,"IDClassB").Cascade.SaveUpdate(); This time B was saved, but by saving B, classA was inserted two times, by A.B and by B.A. How can i solve this problem? Why does it work for the ListB property and not for the B property? Thanks

  • Overwhelmed by design patterns... where to begin?

    - by Pete
    I am writing a simple prototype code to demonstrate & profile I/O schemes (HDF4, HDF5, HDF5 using parallel IO, NetCDF, etc.) for a physics code. Since focus is on IO, the rest of the program is very simple: class Grid { public: floatArray x,y,z; }; class MyModel { public: MyModel(const int &nip1, const int &njp1, const int &nkp1, const int &numProcs); Grid grid; map<string, floatArray> plasmaVariables; }; Where floatArray is a simple class that lets me define arbitrary dimensioned arrays and do mathematical operations on them (i.e. x+y is point-wise addition). Of course, I could use better encapsulation (write accessors/setters, etc.), but that's not the concept I'm struggling with. For the I/O routines, I am envisioning applying simple inheritance: Abstract I/O class defines read & write functions to fill in the "myModel" object HDF4 derived class HDF5 HDF5 using parallel IO NetCDF etc... The code should read data in any of these formats, then write out to any of these formats. In the past, I would add an AbstractIO member to myModel and create/destroy this object depending on which I/O scheme I want. In this way, I could do something like: myModelObj.ioObj->read('input.hdf') myModelObj.ioObj->write('output.hdf') I have a bit of OOP experience but very little on the Design Patterns front, so I recently acquired the Gang of Four book "Design Patterns: Elements of Reusable Object-Oriented Software". OOP designers: Which pattern(s) would you recommend I use to integrate I/O with the myModel object? I am interested in answering this for two reasons: To learn more about design patterns in general Apply what I learn to help refactor an large old crufty/legacy physics code to be more human-readable & extensible. I am leaning towards applying the Decerator pattern to myModel, so I can attach the I/O responsibilities dynamically to myModel (i.e. whether to use HDF4, HDF5, etc.). However, I don't feel very confident that this is the best pattern to apply. Reading the Gang of Four book cover-to-cover before I start coding feels like a good way to develop an unhealthy caffeine addiction. What patterns do you recommend?

  • How do I change a file's path in git's history?

    Here is what I have - a git repo of my code: projects |-proj1 (no git repo here yet) |-subproj1 <- current git repo here Here is what I want - a git repo which is now tracking a new project that uses my code: projects |-proj1 <-git repo moved to here, but still tracking files in subproj1 |-subproj1 (no git repo here) I'd like to keep the history intact and therefore the new repository will be referring to files that are one level deeper than the original. What is the most pain free way to do this?
