• Can't install NetBeans

  - by João Vinholi

  I had never had problems with netbeans installation, but now I am. I have downloaded JDK and JRE properly as I always do and I have started the installation using the terminal as well. When the screen for JDK directory selection comes, I select the JDK folder that I have downloaded, but for some reason the following warning is shown: "An error occurred while validating the path." Do you know what could be?

• Compiz crashes after login

  - by T.Kijas

  after I log-in into Unity, compiz effects are disabled and it says compiz crashes. Restart of them usually works, but not every time. After restart of compiz, compiz works without problems, every effect is OK. I tried latest NVIDIA drivers from xorg-edgers, but situation is the same. I tried to delete folder with compiz settings, but it hasn't helped. I use two LCDs, but with only one enabled, the situation is the same. Thank you for suggestions.

• Genetic Considerations in User Interface Design

  - by John Paul Cook

  There are several different genetic factors that are highly relevant to good user interface design. Color blindness is probably the best known. But did you know about motion sickness and epilepsy? We’ve been discussing how genetic factors should be considered in user interface design in one of my classes at Vanderbilt University School of Nursing. According to the National Library of Medicine, approximately 8% of males and 0.5% of females have red-green color discrimination problems with the most...(read more)

• How to connect to database on remote server

  - by user137263

  Where there is VPN to remote server and then access to the database via local network interface, how can one establish a remote link between one's computer (with a programme such as Visual Studio 2010) and SQL Server (e.g. 2008 R2) ? Any attempts to create a direct link to the SQL Server are blocked. Whilst the SQL Server can be configured to allow external access, this provides its own host of problems. Any help would be much appreciated.

• Mouse Not Working Properly

  - by James

  I just did a clean install of Ubuntu 11.10 but for some reason the mouse isn't working properly. Problems I'm experiencing are: left button on the mouse doesn't work, the cursor doesn't highlight anything, as well, the right side will not do a double click function. Doesn't seem to bring up the mouse menu to "go back" as well, "go forward" options. In order to make things work, I have to use the Enter key, and arrow keys.

With 'using OpenGL' I mean: Creating and managing an OpenGL window Actually using the OpenGL API Handling user-input (keyboard/mouse)

  - by boj

  Possible Duplicate: What are some good tools for introducing kids to programming? Long-long time ago I had a great book by Frank DaCosta about writing adventure games in Basic, it had a great influence on me. I would like to show the world of programming to my child too but I have two problems: I can not found books like DaCosta's (but we can replace it with our fantasy so not a big deal) Which programming language should I use? Small Basic?

• SPC 300nc webcam doesn't work on 64-bit Ubuntu 11.10

  - by Felix Elnan

  It seems that this solution to webcam problems in Ubuntu 11.10 doesn't work in the 64 bit version. If i run the following command: "LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so skype" all i get is: "ld.so: object '/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so' from LD_PRELOAD cannot be preloaded: ignored." and if i try: "LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l2convert.so skype" I get the same problem :( Does anyone have a solution?

• Companion Book for Cormen

  - by Robert S. Barnes

  I asked this question on Stackoverflow and they suggested it was more appropriate here. I"m taking a course soon based on the first fourteen chapters of Cormen's Introduction to Algorithms. The course is based on a translation of the 2003 edition. I have two questions: Is it recommended to get the newer 2009 edition and what are the differences? Can anyone recommend a good companion text which has more worked problems and less, "this clearly works" type explanations?

• 5 ways to stop code thrashing&hellip;

  - by MarkPearl

  A few days ago I was programming on a personal project and hit a roadblock. I was applying the MVVM pattern and for some reason my view model was not updating the view when the state changed??? I had applied this pattern many times before and had never had this problem. It just didn’t make sense. So what did I do… I did what anyone would have done in my situation and looked to pass the blame to someone or something else. I tried to blame one of the inherited base classes, but it looked fine, then to Visual Studio, but it seemed to be fine and eventually to any random segment of code I came across. My elementary problem had now mushroomed into one that had lost any logical basis and I was in thrashing mode! So what to do when you begin to thrash? 1) Do a general code cleanup – Now there is a difference between cleaning code and changing code . When you thrash you change code and you want to avoid this. What you really want to do is things like rename variables to have better meaning and go over your comments. 2) Do a proof of concept – if cleaning code doesn’t help. The  you want to isolate the problem and identify the key concepts. When you isolate code you ideally want it to be in a totally separate project with as little complexity as possible. Make the building blocks and try and replicate the functionality that you are getting in your current application. 3) Phone a friend – I have found speaking to someone else about the problem generally helps me solve any thrashing issues I am having. Usually they don’t even have to say anything to solve the problem, just you talking them through the problem helps you get clarity of mind. 4) Let the dust settle – Sometimes time is the best solution. I have had a few problems that no matter who I discussed them with and no matter how much code cleaning I had done I just couldn’t seem to fix it. My brain just seemed to be going in circles. A good nights rest has always helped and often just the break away from the problem has helped me find a solution. 5) Stack overflow it – So similar to phone a friend. I am really surprised to see what a melting pot stack overflow has been and what a help it has been in solving technology specific problems. Just be considerate to those using the site and explain clearly exactly what problem you are having and the technologies you are using or else you will probably not get any useful help…

• Headphones don't work on an Acer Aspire 5920g

  - by Dave Chatelain

  All the problems I read about were all about the sound not working when they plugged the headphones in. I have the problem that my mic will work but the sound is still played on my built-in speakers. When I look at the sound settings, it doesn't give me any options for headphones. I run 12.04 and never had this problem in Windows. I run it on a Acer Aspire 5920g. Any tips or ideas will be very helpful.

• Kernel Panic Troubleshooting For Dummies

  I have made Ubuntu my primary OS since 10.04, and I have converted many of my friends and neighbors into Ubuntu users since then. I am the fix-it guy they approach when they encounter problems. The most frantic calls I get are when they encounter an "update-induced kernel panic." (Many human beings are allergic to command-line interfaces and search engines.) What are the step-by-step procedures to resolve an "update-induced kernel panic"?
