  • Silverlight 4 + RIA Services - Ready for Business: Exposing Data from Entity Framework

  • Why does IDLE continue to crash? [migrated]

    - by Dyana
    Idle keeps crashing and I can't figure it out. After restarting the computer and reinstalling Python, none of which seemed to work, I looked to my peers and was told to "install one of the Tcl/Tk". After getting another opinion I was also told that I already had this and found it to be true but decided to try it anyway since it continued to crash. Nothing has improved and I have an assignment due. Any ideas on why this continues to happen and what I can do to fix the crash? Problem details: Process: Python [1183] Path: /Applications/Python 3.3/IDLE.app/Contents/MacOS/Python Identifier: org.python.IDLE Version: 3.3.0 (3.3.0) Code Type: X86-64 (Native) Parent Process: launchd [793] Date/Time: 2012-11-05 14:10:54.124 -0500 OS Version: Mac OS X 10.7.5 (11G63) Report Version: 9 Interval Since Last Report: 181805 sec Crashes Since Last Report: 4 Per-App Interval Since Last Report: 20 sec Per-App Crashes Since Last Report: 4 Anonymous UUID: 68994A08-7FFB-4074-A553-CB60A60BB412 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Application Specific Information: * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Error (1007) creating CGSWindow on line 263'

  • Can I make Launcher icons dark/dim unless app is running (then in color)?

    - by Greg
    To improve visibility of what Launcher-Applications I have running (instead of relying solely on that small right-facing triangle), is it possible to make Launcher-icons default to a black&white/dark/dim state? And then when a launcher-icon is clicked (or the super+# shortcut used) that icon would gain color and backlight signifying the app is running? If the Launcher icon's app is not running, it is dimmed out. If the icon's app is running, it is showing in color and backlit. I'd prefer an "inhouse" solution as opposed to having to install additional software, but I'm interested in hearing all options for if this is possible.

  • Google veut doper l'adoption professionnelle de ses Google Apps avec un réseau de partenaires-revendeurs de plus en plus important

    Google veut doper l'adoption professionnelle de ses Google Apps Et mise sur un réseau de partenaires-revendeurs de plus en plus important Souscrire aux Google Apps for Business est on ne peut plus simple. Il suffit d'ouvrir un compte et un domaine. Les applications hébergées sont alors immédiatement accessibles et fonctionnelles. Cela, c'est pour la théorie. Dans la pratique, ce genre de choix implique très souvent de la part des entreprises une migration (de Outlook et Exchange vers Gmail par exemple), ou une articulation avec l'existant (entre Microsoft Office et Google Docs pour citer un autre exemple fréquent).

  • How do I screen-capture an inactive window?

    - by Wassasin
    How can I screen-capture an inactive (minimized / on another workspace) window in Ubuntu? Applications like ImageMagick's import are only able to capture active windows. When attempting to capture an inactive window, I get the following message: unable to read X window image `<id>': Resource temporarily unavailable @ error/xwindow.c/XImportImage/5023. Might be able to do this using Compiz, as it is able to render previews of inactive windows. Furthermore, in my specific case, the window I want to capture is run in a Wine Explorer-container. Inside that container the application is always active.

  • How to teach your users/customers to send better error descriptions

    - by ckeller
    I often have to deal with customers or users which are reporting errors in applications. Most of the time their content is something useless as ERROR!!! x does not work without much more information. For resolving the issue I have to request every single detail of them, which often is more time consuming than fixing the issue itself. Other send information in formats which are not ideal, like screenshots (of data records, not of errors) although they could send a link (we have access to the systems) and so on. How do you tell your users/customers to describe the problems with more details so that the whole process could be easier for both sides? edit This question is more about the social skills, than how to achieve programmatic collection of logs and error information. I'm aware of the fact that this should be part of good software design.

  • What should be learned for someone starting in Android Games?

    - by user14544
    I know this might be a little subjective. But I've read the other questions. A lot of answers kept on popping up like to use box2d, libgdx, andEngine, etc. So the real question is, what would be the best to start off with as a beginner. I have some experience with java code, just by reading about in the Oracle Docs. I've gone through Flash and Eclipse. When i mean gone through, i don't mean i have actually created my own game from Flash or Eclipse, but i just learn things here and there. Currently I'm reading Beginning Android for Beginners but I don't have the knowledge to implement my own Ideas into the game tutorials because of lack of experience. I'm looking for a way to learn how to program to create games for Android. While at the same time get experience from programming. I do not want to learn those drag and drop game making applications such as GameMaker.

Pour l'instant, Adobe dit n'avoir trouvé que deux logiciels malveillants qui utilisent cette ...

  • What is the best way to learn C# programming? [closed]

    - by MSU
    My case I want to get the capability of doing anything in C# from building applications to solving problems. I searched for and tried to read books. Then one of the experts said that reading books will not make any good and that to learn, you have to solve real world problems in C#, and he gave me some problems which I previously solved in C++. The thing is that while I know the internal logic of solving the problem, I don't know how to implement it using C# efficiently. I know the message to pass but not the exact way to pass it. I did a program to solve a problem, then find out there are much easier ways of doing it wherever I was doing it in tougher way. What I need to get hold of the language and get the ability to code in C# proficiently?

  • No splash screen on hibernate

    - by Marky
    Hibernate is working fine. A bit slow when resuming from a hibernate but I can bear with it just so that I have all open applications on the desktop as I left it. Then again the "slowness" might be because of the 4GB RAM, although I'm assuming only what is used gets swapped and not the entire memory. Going back, my question is has anyone been able to make Ubuntu show a splash screen or some kind of indicator/progress bar to show while hibernating or while resuming? I remember with SuSE on my HP Compaq Presario notebook it had messages appear during and after. Better than nothing, I guess. Thanks in advance! :D

  • How to update all the installed software in Ubuntu without using any PPA?

    - by Suchith JN
    I've got many softwares installed. But when the new version is released I'm not getting notified from the application that an update is available. And I found that in most of Ubuntu applications the Update option is not available. I should wait for the next release for an updated version of the software. I've been updating Mozilla using the packages available from their PPA. In ubuntu is there any way to update the softwares without using any PPAs? Please don't recommend Build from source method since I don't like to do all those weird stuff like configuring the things manually etc.

    Just a heads up from DevFish (http://devfish.net), a free book on writing applications for Windows 8using html, css and javascript by Kraig Brockschmidt . You can find the book here: http://blogs.msdn.com/b/microsoft_press/archive/2012/10/29/free-ebook-programming-windows-8-apps-with-html-css-and-javascript.aspx I have not finished reading this but so far it looks like it will be a great resource if you have any interest in trying the windows 8 javascript programming model. Besides all the aspects of controls, library support and animations the book also talks about how to make your own components in c#, vb or c++.

  • Algorithm for Learning development

    - by user9057
    This is a fairly general question. I know a bit of Perl and Python and I am looking to learn programming in more depth so that once I get the hang of it I can start developing applications and then websites. I would like to know of an algorithm (sequence of steps :)) that could describe my approach towards learning programming in general. I have posted small questions on Perl/Python and I have recieved great help from everyone. Note:- I am not in a hurry to learn. I know it takes time and that's fine. Please give any suggestions you think are valid. Also, please don't push me to learn Lisp, Haskell etc - I am a beginner.

  • Personal Activity Monitor tracks time you spend using desktop apps

    Up until a couple of years ago, I used to turn to RescueTime to figure out how I spend my time online. Then it got too complex, and I stopped using it. Personal Activity Monitor is like a vastly dumbed-down version of RescueTime, and I mean that as a compliment. It's free and bare-bones -- all it does is track what applications you're using and for how long. A big drawback at this point is that it doesn't integrate with Web browsers to help you analyze how you spend your time on the Web. Still, if your work doesn't require constant Web app use, knowing how long you've used a browser overall might be enough to help you manage your time. This is far from the only application in this space -- alternatives such as Slife and Chrometa are full-featured and impressive -- but PAM is good option for those who want a nice, simple tracker.Personal Activity Monitor tracks time you spend using desktop apps originally appeared on Download Squad on Sat, 05 Mar 2011 10:00:00 EST.

  • Downsides of using Lubuntu on a good computer [closed]

    - by Yamitatsu
    I have a simple question but yet, hard to find any anwser on it. Are there any downsides of using Lubuntu on a good laptop ? Ihe one I purchased would run Ubuntu really good, but I like the look & feel of Lubuntu. I mainly use it to code or watch movie / listen music, usually a load of applications opened at the same time, 20+ tabs on multiple web browser, etc.. Since Lubuntu is lightweight, i wonder if it lacks of some useful functions or something like that.
