• How to set up a SPF record?

  - by MeltingDog

  The clients on my VPS are all getting spammed. The spam seemingly comes from their own email addresses - it is clear that somehow something got into my VPS and was able to capture all the email addresses that existed and is now using them to send spam. I was advised to set up a SPF record, but I am unsure what this is or how to go about it. After reading, I have figured out how to create one in CPanel, but I cannot find what to do with it now. Do I copy it into somewhere in my DNS records in Zone Management? Can anyone point me in the right direction?

• Gnome Classic U 11.04 trash not working, can't find my trash dir

  - by Bruce Salem

  I did an upgrade from U 10.10 to U 11.04. I can't upgrade further because Upgrade Manager says that there are unsupported packages. How do I find them? A more immediate problem is that trash stopped working even though "/.share/local/Trash is getting files removed by the file manager. The trash icon on the lower panel fails after having done the upgrade from Gnome 2 to Unity and using Gnome Classic, says "No Such File or Directory". File Operations says it is looking at "/". How do I reconfigure the trash icon to use my local trash dir? The trash dir is there, has the right permissons, I can "rm" the dir tree there, and recreate it by moving files to the trash from the file manager.

• jungledisk fails with libnotify error

  - by Angelo

  Has anyone had success getting the jungledisk application to work under Ubuntu? I installed it from the .deb file provided by jungledisk. The install goes fine, but I can't get the "jungle disk desktop" app to launch. It appears in the dash search bar, but doesn't launch or do anything upon selecting it. When I try the command line, I get the following... $ jungledisk -V -f Verbose mode enabled Shutting down... $ I get something more interesting with the following command ... something about libnotify.so $ junglediskdesktop -V -f junglediskdesktop: error while loading shared libraries: libnotify.so.1: cannot open shared object file: No such file or directory Does anyone have suggestions for what to try?

• What makes a good developer / system documentation?

  - by deamon

  Much time is wasted to get new developers started with existing software systems, because there is no good documenation. But what makes a system documentation good? One thing is a good API documentation like the Java API doc, but how to transfer the "bigger picture" and other things that cannot be placed in the API doc? One constraint is that it should not be to hard and time consuming to write the docs, because that is one reason why it is omitted so often. So, what makes documentation good?

• Innovation on CS

  - by guiman

  Hi all, its been some time that i've been thinking about creating something that could help the web community and leave some mark, but the problem that there are no ideas poping out of my head. So 2 questions comes to my mind: First, how did projects like Twitter, Google or any other big project that had changed our way of living in the internet get started? Secondly, do we have to force it or just keep doing what we do best and wait to that idea that could change things? While writting this question, one quote come to mind: Imagination is more important than knowledge Albert Einstein

• Desktop top is lower than it should be

  - by Idan Arye

  I have a very odd problem with Ubuntu 11.10. Here is a picture of it: The window in the picture is maximized, but for some odd reason it does not cover the entire desktop area. That area of the desktop the window does not cover is a dead area - I also can't drag desktop items to there, though I can drag not-maximized windows to that area. Rebooting doesn't help. The problem started after I configured some windows partitions to automount on startup(though I don't see how that could cause the problem...) Does anyone know a way to fix this?

  In my office I've Ubuntu 8.10 desktop installed and it's running for a long time. When ever the system is started, I'll get a file system maintenance error and something it's prompted for the root password or (press ctrl+d to continue). After pressing Ctrl+D the system normally boots up. I could not resolve this issue for a long time and I think something should be done in the fstab file. I'm not sure to do anything and expecting the experts here to help to perfectly fix this. Any help is appreciated. Thanks!

• android: How to apply pinch zoom and pan to 2D GLSurfaceView

  - by mak_just4anything

  I want to apply pinch zoom and panning effect on GLSurfaceView. It is Image editor, so It would not be 3D object. I tried to implement using these following links: https://groups.google.com/forum/#!topic/android-developers/EVNRDNInVRU Want to apply pinch and zoom to GLSurfaceView(3d Object) http://www.learnopengles.com/android-lesson-one-getting-started/ These all are links for 3D object rendering. I can not use ImageView as I need to work out with OpenGL so, had to implement it on GLSurfaceView. Suggest me or any reference links are there for such implementation. **I need it for 2D only.

• Working on someone else's code

  - by Xavi Valero

  I have hardly a year's experience in coding. After I started working, most of the time I would be working on someone else's code, either adding new features over the existing ones or modifying the existing features. The guy who has written the actual code doesn't work in my company any more. I am having a hard time understanding his code and doing my tasks. Whenever I tried modifying the code, I have in some way messed with the working features. What all should I keep in mind, while working over someone else's code?

• What options do individual have to fork a project?

  - by skrco

  Let's assume our example individual has an idea, engagement, ... to fork project. By project I mean any kind of software - thick client, web site, portal, service, driver, plc, ... - anything that can be programmed. Motto of question: What options do our example individual have to fork this project from the early beginning through getting collaborators and users to mature software? Here are the main subquestions: Sandbox phase: Where can he announce his idea and proposal and receive positive/negative critic and feedback? Development phase: Where can he build his team to work on this project? Yet deployed phase: Where can he schedule tasks, assign tickets and bugs to be solved? and the list can go on... What really interests me is the "sandbox phase question".

• Hosting a web application on discountasp.net using sql ce 5

  - by David Stanley

  I am hoping that someone may have experience with this, since the discountasp site is very lacking in straightforward answers. I am building a lightweight web application and have decided to have sql ce as the database for it. Two questions regarding this: Do i need to get an actual database hosted as well as the site, in order for it to work? Do you know if discountasp supports the use of sql ce (not with webmatrix or any cms builds, completely custom)? If they don't, do you have any experience/recommendations with getting this done?

• restoring grub when Windows 7 MBR lost it

  - by Trent Hall

  My dual boot desktop was running only Windows 7 until it crashed on a windows update. Couldn't get it started again even after all the usual things that might fix it, so I installed Ubuntu 12.04, which has worked very well. unfortunately Carbonite doesn't run on Linux yet, and so I called Microsoft support to see if we could be Windows 7 up and running. Their attempts to get Windows 7 running resulted in writing a new MBR for windows, which failed and also somehow caused the loss of ability to boot into Ubuntu also. How can I get back to Ubuntu? I don't want to lose my settings in Ubuntu. Thanks... Trent

• What are the warning signs of impending doom to watch out for on a project?

  - by ConroyP

  Having worked on a failed project is one of the few things that most programmers have in common, regardless of language used, industry or experience. These projects can be great learning experiences, soul-crushing disasters (or both!), and can occur for a multitude of reasons: upper management change of heart under-skilled / under-resourced team emergence of superior competitor during dev cycle over/under management Once you've worked on a couple of such projects, is it possible to recognise at an early stage exactly when a project is doomed to fail? For me, a big sign is having a hard & fast external deadline combined with feature creep. I've seen projects which were well planned out and proceeding right on schedule go horribly off the rails once the late feature requests started to roll in and get added to the final "deliverable". The proposers of these requests earned the nickname of Columbo, due to rarely leaving the room without asking for "just one more thing". What are the warning signs you look out for that set off the alarm bells of impending doom in your head?

• How to achieve uniform speed of movement on a bezier curve in cocos 2d?

  - by Andrey Chernukha

  I'm an absolute beginner in cocos2 , actually i started dealing with it yesterday. What i'm trying to do is moving an image along Bezier curve. This is how i do it - (void)startFly { [self runAction:[CCSequence actions: [CCBezierBy actionWithDuration:timeFlying bezier:[self getPathWithDirection:currentDirection]], [CCCallFuncN actionWithTarget:self selector:@selector(endFly)], nil]]; } My issue is that the image moves not uniformly. In the beginning it's moving slowly and then it accelerates gradually and at the end it's moving really fast. What should i do to get rid of this acceleration?

• Why opening Ubuntu's default wallpaper (warty-final-ubuntu.png) in Image Viewer always fails?

  - by Kush

  Everytime I try to open Ubuntu (any version, since from 8.04 with which I started) default wallpaper, named "warty-final-ubuntu.png", I get the following error. I have also reported bug for the same, more than a year ago but it is still unresolved. Also I don't get the point why the default wallpaper is still named as "warty-final-ubuntu.png" instead of having actual code name prefix to which wallpaper belongs eg. "precise-final-ubuntu.png" and so on. General Thoughts Lots of community effort goes under development of this marvelous distribution but we're still missing out to fix such silly issues, which is directly/indirectly affecting the number of new adopters.

• Good Practices for writing large (team/solo) projects (In C)

  - by Moshe Magnes

  Since I started learning C a few years ago, I have never been a part of a team that worked on a project. Im very interested to know what are the best practices for writing large projects in C. One of the things i want to know, is when (not how) do I split my project into different source files. My previous experience is with writing a header-source duo (the functions defined in the header are written in the source). I want to know what are the best practices for splitting a project, and some pointers on important things when writing a project as part of a team.
