• How to generate `AllowDeactivateGrabs` in command line ?

  - by boffin

  I am using XFCE-Ubuntu and do a lot of my development work there. In my case, when I sometimes use Xilinx ISE, the mouse cursor hangs as a Grab pointer and then stops responding. The entire X environment becomes unusable and I have to kill it and restart. This is becoming a serious annoyance. I saw this bug: AllowDeactivateGrabs is broken I see that sending AllowDeactivateGrabs in command line can kill the Grab. In my case, I am doing this on a remote server, so it is the application in the remote server (over X2GO) getting messed up. I am able to login in command line and kill X. Is there a way to generate AllowDeactivateGrabs in command line ? So I dont mess up my other applications and potentially lose data.

• 2D Game Development dynamics in c++ [on hold]

  - by novice

  I am new to developing computer graphic applications in c++ using OpenGl. I want to develop games but I really am facing problems when it comes to understanding concepts like trajectory, collisions, gravity and also the use of various physics engines that are available. when i search the internet I kind of get lost because they aren't for beginners like me. There is some hardcore mathematics, physics and coding involved. I need to pick the concepts that are mostly needed in game dev like trajectory, collision etc. Any good tutorials that can help me out in picking these concepts from the start.

• Why support IE6?

  - by TATWORTH

  The question has been raised as to why support IE6? I can give you two reasons, why your client will require IE6 to be supported: While IE6 continues to have above a certain of browsers in use The web application is for a controlled environment that has not been upgraded from IE6 to a later version I personally only use any current or previous version of IE to: To access the Windows Update site As required to test IE compatibility of applications that I write I agree that that the CSS fixes required to support IE6 are undesirable in that they require non-standards compliant CSS. I prefer that my HTML be both XHTML and CSS standards complaint according to the W3C tests. IE9 promises to be not only standards compliant but much better in performance. I am looking forward to its release.

• How can I pull data from PeopleSoft on demand?

  - by trpt4him

  I work in IT at a university and I'm working with about 5 different departments to develop a new process for students to apply to a specific school within the university (not the university as a whole). We're using a web-based college application vendor and adding the applicant questions for the school itself to the main university application. Currently the main application feeds into PeopleSoft. The IT staff here is building a new table to hold just our school's applicant data. I want to be able to access that data from PeopleSoft for use in external applications, but our IT staff doesn't really seem to understand what I'm requesting, as they simply tell me I can have access to the PS query tools. The problem is, I don't want to run just ad hoc queries, I want to be able to connect from outside PeopleSoft and show current data within the external app. I am unable to find documentation or get a clear answer to my question. Does PeopleSoft support access via a web services API or anything similar, and does that sound like the right direction for me to take?

• More complex learning source for C# .NET [closed]

  - by Leron

  By complex I don't mean more difficult but including a larger area of possibilities cover. I've started a few years ago with PHP and the transition from learning the syntax of the language and the basic logical structures to working with databases, including JavaScript and so on was very short. And now I'm more interested in studying working with languages like Java/C#. Recently I spend a lot of time reading and writing some simple console applications, I've read almost 2K pages for C# programming and still don't know how to connect to database for example. Just for info I'm interested in web development, socket programing and live streaming, don't know if I'm exceeding myself too much writing that but despite that I want to find some books/internet sources where I can extend my current knowledge of C#/.NET, start using database queries, maybe try something more complicated webwise.

• News about Programming Entity Framework 2nd Edition

  Programming Entity Framework 2nd Edition (based on the RTM of VS2010/.NET 4.0) is currently available on Safari Rough Cuts at http://oreilly.com/catalog/9780596807252. At this point most of the chapters are there. You’ll find 2-23. Note that chapter 4 will be broken into 4 and 5 in the final edition. I changed the chapter numbering after chapter 16 to accommodate this which is why there is no chapter 17. Chapters 24 is about n-Tier CLient applications using an WPF example and chapter 25 is...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Missing Firefox app icon

  - by frozenkoi

  I'm using Ubuntu 11.04 (upgraded from LTS 10.04) and Firefox (version 11) doesn't show it's icon in the Window List panel, in the Firefox window top left corner (system menu) nor when using ALT+TAB to switch applications. I'm using unity 2D since I'm running ubuntu as a guest in a VMWare virtual machine (Host is windows 7) Instead of the Firefox icon I get what appears to be a generic icon that looks like an app window in the window list and a black rectangle with a curl in the bottom right corner in the ALT+TAB window. How do I fix this so that the proper Firefox icon gets displayed? EDIT: Depending on the icon set chosen in the Appearence settings window sometimes I get the icon, sometimes I don't. When using Ubuntu classic none of the icon sets provide the icon for Firefox.

• UK Data Breaches Up by 10 fold in 10 years.

  - by TATWORTH

  At http://www.v3.co.uk/v3-uk/news/2201863/uk-data-breaches-rocket-by-1-000-percent-over-past-five-years there is an interesting report on the increase in data breaches reported in the UK.A lot of this increase may simply a change in legislation that has made reporting a statutory obligation.Some questions to ask yourself:Are server logs checked for untoward activity?Do you have a reporting policy if something is amiss?Did you design security in for the start of your application design?Do you log for example failed logons?Do you run tools to check for code integrity?Is my defense, a strategy of defense in depth?Do you realise that 60% of hack attacks are internal?Whilst SQL Injection is a problem that affects practically all application code platforms, within Microsoft Applications do you run FXCOP? Do you run any of the other free tools for checking?

• @OnStart & @OnStop

  - by Geertjan

  In applications based on NetBeans Platform 7.2, you'll be able to replace all your ModuleInstall classes with this code: import org.openide.modules.OnStart; import org.openide.modules.OnStop; @OnStart public final class Installer implements Runnable { @Override public void run() { System.out.println("enable something..."); } @OnStop public static final class Down implements Runnable { @Override public void run() { System.out.println("disable something..."); } } } Build the module and the annotations result in named services, thanks to @NamedServiceDefinition: Aside from no longer needing to register the ModuleInstall class in the manifest, performance of startup will be enhanced, if you use the above approach: https://netbeans.org/bugzilla/show_bug.cgi?id=200636

• What is the relationship between OpenGL, GLX, DRI, and Mesa3D?

  - by user65308

  I am starting out doing some low-level 3D programming in Linux. I have a lot of experience using the higher level graphics API OpenInventor. I know it is not strictly necessary to be aware of how all these things fit together but I'm just curious. I know OpenGL is just a standard for graphics applications. Mesa3D seems to be an open source implementation of this standard. So where do GLX and DRI fit? Digging around on Wikipedia and all these websites, I've yet to find an explanation of exactly how it all goes together. Where does hardware acceleration happen? What do proprietary drivers have to do with this? Thanks!

• Popper Email Notifier not working

  - by Joel

  Using Maverick 64bit I downloaded Popper Email Notifier today. Installed it from the v023 deb. https://launchpad.net/popper I configured it, and the TEST tab shows I configured everything properly. I can't get Popper to appear in the notification menu. I have restarted gnome-pannel, restarted my computer, reinstalled the app. No luck. I checked the /usr/share/indicators/messages/applications/ folder, and there's only the defaults there. Anyone know how to fix this? Even if someone knows what file I can drop into that folder to make it work that'd be great. Edit: I wonder if it's because I removed the evolution-indicator package? Thanks!

• Does anyone have a specific example of using the Flyweight Pattern?

  - by Jeremy E

  I have been studying design patterns and came accross the fly weight pattern. I have been trying to see opportunities to use the pattern in my applications but I am having trouble seeing how to use it. Also, what are some signs that a fly weight pattern is being used when I read other peoples code? According to the definition it says: Use sharing to support large numbers of fine-grained objects efficiently. If I read it right Dictionaries and Hashtables could be instances of fly weights is this correct? Thanks in advance.

• Will the world depend less of developers?

  - by nmiranda

  Hi everybody, yesterday I had a little chat with a friend that is in the field of development as I am. And he told me that he planned to change of business, I mean, he wants to get off developing cause he doesn't think that it has future. "There will come days were you could have a job as a developer but you would never get rich" he said. "Nowadays is more important to have an idea and develop it in a product than being a software developer. Today you can find a lot of applications that can help you to make it. We have already non-sql databases, better cases than 10 years ago and other tools much of them free, everything is directed to depend less of developers and you'll see it more 10 years from now" Do you agree with that?

• As a minor, how can I make programming profitable? [closed]

  - by lesderid

  Possible Duplicate: Can I be “too young” to get a programming job? I’m 15 and I want to Freelance I've always loved programming. I started when I was about 8 with making some silly WinForms applications in VB.Net that basically did nothing. Now, I'm 15 and I would say I'm quite good C# and I'm reading through Jon Skeet's C# In Depth. I also have some experience with VB, C++ and Assembler (mostly reverse engineering). I really love coding, which got me wondering about college, what I can study to get into the software business. However, I would like to earn some money now, so I can spend it on better hardware, on development tools or on other hobbies. This is hard because I don't have any work experience nor have I done any programming-related studies. It's also not legal for me to do any freelancing jobs as I'm under the age of 18. How can I use my current experience at my age to earn some money?

• lower graphics setting in ubuntu

  - by zkent

  First off, I am new to Ubuntu. I come from a Windows background (DOS before that) and am loving it so far. I installed it on an older Dell laptop that I wanted to get another year out of. I set this machine up primarily as a LAMP development machine for a project I am working on. The machine is a Vostro 1500 and it has 4GB RAM (maxed) and an upgraded hard drive. I can't watch YouTube videos for long before it starts to overheat and start acting sporadic. I can live without YouTube but every so often the application switching (alt-tab) gets slower and begins not showing all applications and the Dash home quits displaying properly. I am sure I am asking a lot of this old machine. What I really want to know is: are there any settings in Ubuntu that allow me to lower the graphic effects (fade-ins, transparencies, fancy transitions, etc) that would be less taxing on the video card?

• Learning PHP MySQL [closed]

  - by Keith Groben

  I've been a designer for several year now. I'm now very interested in learning PHP, MySQL. I've read through W3Schools already and it helped me become familiar. I now want to know where I could go to start building some simple database and php applications so I could be come familiar with coding and start to improve. I think hands on application is the best way to learn. Since I'm a beginner, much of what I've found so far is sort of advanced to me.

• Why doesn't `unity --reset` work?

  - by Elshaer

  I want to reset Unity. But when I type unity --reset I get the following error: Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Compiz (opengl) - Fatal: glXCreateContext failed Compiz (bailer) - Info: Ensuring a shell for your session ... I am not using Compiz! I am using Metacity. Thanks a lot :) EDIT: I am using Unity. And I want to reset it as the sidebar is always shown when I am viewing my desktop (although it hides automatically if I am using other applications) and Alt+Tab switches the windows in a different, poor way (not the default one of Ubuntu 11.10).
