  • What is the closest thing MATLAB has to namespaces?

    - by rlbond
    We have a lot of MATLAB code in my lab. The problem is there's really no way to organize it. Since all the functions have to be in the same folder to be called (or you have to add a bunch of folders to MATLAB's path environment variable), it seems that we're doomed have loads of files in the same folder, all in the global namespace. Is there a better way to organize our files and functions? I really wish there were some sort of module system...

  • Is there a Moria like theme for Visual Studio 2010?

    - by Junior Mayhé
    Is there some cool Moria like theme for Visual Studio 2010? Mine is highlighting gray font with gray background! I just can't configure it on Tools-Options-Environment-Fonts and Colors menu. Visual Studio doesn't seem to show an item for this "highlighting keyword/tag system". You select a variable on variable called myVar, and it highlights all with the same name but with a grayer color and gray background. I just can't read it and can't set it.

  • Running OpenMPI on Windows XP

    - by iamweird
    Hi there. I'm trying to build a simple cluster based on Windows XP. I compiled OpenMPI-1.4.2 successfully, and tools like mpicc and ompi_info work too, but I can't get my mpirun working properly. The only output I can see is Z:\orterun --hostfile z:\hosts.txt -np 2 hostname [host0:04728] Failed to initialize COM library. Error code = -2147417850 [host0:04728] [[8946,0],0] ORTE_ERROR_LOG: Error in file ..\..\openmpi-1.4.2 \orte\mca\ess\hnp\ess_hnp_module.c at line 218 -------------------------------------------------------------------------- It looks like orte_init failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during orte_init; some of which are due to configuration or environment problems.

What my problem is and how do I fix it? Upd: Ok, this problem seems to be fixed. It seems to me that WideCap driver and/or software components causes this error to appear. A "clean" machine runs local task successfully. Anyway, I still cannot run a task within at least 2 machines, I'm getting following message: Z:\mpirun --hostfile z:\hosts.txt -np 2 hostname connecting to host1 username:cluster password:******** Save Credential?(Y/N) y [host0:04728] This feature hasn't been implemented yet.

Can anyone help me? Upd2: Error code -2147024891 might be WMI error WBEM_E_INVALID_PARAMETER (0x80041008) which occures when one of the parameters passed to the WMI call is not correct. Does this mean that the problem is in OpenMPI source code itself? Or maybe it's because of wrong/outdated wincred.h and credui.lib I used while building OpenMPI from the source code?

  • Specifying the range of supported Rails versions in a project

    - by Tomas Sedovic
    The config/environment.rb of my rails project contains this line: RAILS_GEM_VERSION = '>= 2.3.2' unless defined? RAILS_GEM_VERSION Which makes sure that only Rails of version 2.3.2 or greater will be used to run this app. Is there a way of specifying both the lower and the upper boundary at the same time? So that it would run, say, only on versions higher than 2.3.1 and lower than 2.3.6?

  • On what platform did these popular programming languages originate?

    - by speciousfool
    Perhaps you know the story of HTTP and HTML being developed on a NeXT computer. I am curious which platform served as the first home for these programming languages: Ada C C++ C# D Erlang Fortran Haskell Java Javascript Lisp Logo MATLAB ML Perl PHP Prolog Python R Ruby Scheme SQL Smalltalk I thought it might be interesting to reflect on how the machine and operating environment lead to different design decisions. Or to see if some architecture or operating system variant was particularly fruitful for programming language development. A question for the historians among us.

    Is there something similar to jQuery's live()-method in dojo? I have some content that's being loaded with ajax, and need that content to get the same event connections. dojo.query(".allTheseElements").connect("onclick", function() { /***/ } And then have the dynamically loaded content fire on this too.

  • Responsive grid, floated elements move underneath one another when min-width is reached

    - by Francesca
    I'm in the process of creating a responsive site (currently only working on the main content.) I've created two floated divs with percentage based widths. One contains an image which resizes with the browser resizing. The image has a min-width of 100px. Can anyone tell me why when put into a mobile sized width it doesn't drop down? How can I make the image stack underneath the text? JS Fiddle Live site

  • jQuery action being called when selector isn't met?

    - by dougoftheabaci
    I've been working on a prototype for a client's web site and I've run into a rather significant snag. You can view the prototype here. As you can see, the way it works is you can scroll a set of slides horizontally and, by clicking one, open a stack containing yet more slides. If you then click again on an image in that stack it opens up a lightbox. Clicking on another stack or the close button will close that stack (and open another, as case may be). That all works great. However you get some weird behavior if you do the following: Click to open any stack. Click to open an image's light box (this works best if you click on the image that's level with the main list). Close the light box and the stack either by clicking the close button or clicking on another stack. Click back to the first stack. Instead of reopening the stack, you get the lightbox. This confuses me as the light box should only ever be called if there is a class on the containing UL and that class is removed when the lightbox is closed. I've checked and double-checked this, it's definitely missing. Here are the respective functions: $("ul.hide a.lightbox").live("click",function(){ $("ul.show").removeClass("show").addClass("hide"); $(this).parent().parent().removeClass("hide").addClass("show"); $("ul.hide").animate({opacity: 0.2}); $("ul.show").animate({opacity: 1}); $("#next").animate({opacity: 0.2}); $("#prev").animate({opacity: 0.2}); return false; }); $("ul.show a.lightbox").live("click",function(){ $(this).fancybox().trigger("click"); return false; }); As you can see, in order for the lightbox to be called the containing UL has to have the class of show. However, if you check it with Firebug it won't. For those who are curious, the added .trigger("click"); is because the lightbox will require a double-click to launch otherwise. Any idea how I can fix this?

  • Use a Datamodule in a Service Application

    - by O Engenheiro
    I wrote my Win32 App to test and debug. I've created a datamodule with all functionality needed to run the TCP sockets and IBDatabase components. After successfully testing the Datamodule in the Win32 application environment I am trying to hook the Datamodule into a Service Application template that I created, I can get nowhere in getting it to run. Could someone indicate whether this strategy of using a Datamodule with Component functionality encapsulating the primary service functions is workable and give a simple template example of how to hook it up if it is??

  • MVC 4 iframe embedded in desktop page showing mobile view

    - by Reto Laemmler
    I use Index.cshtml and Index.mobile.cshtml. My Index.cshtml is a mobile app landing page containing an iframe to live demo the mobile web app. Index.mobile.cshtml is the mobile web app itself. The problem is, the iframe keeps loading the desktop version itself. As far as I know, I cannot configure the user agent of the iframe to a mobile type. It should be solvable with some routing but I couldn't figure out how!?
