• 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?

• How do I disable Caps Lock by command line?

  - by Echogene

  For some reason my laptop is stuck in Caps Lock. I have the Caps Lock key mapped by xmodmap to hyper_l, so I don't have a caps_lock key to turn it off. Is there a way I can turn it off by command line? It would be nice if I could reset the lock state without resetting my computer, especially for future reference. This has happened before, but I would like to know now how to do it properly this time.

• Why aren't web frameworks simple, elegant and fun like programming languages? [on hold]

  - by Ryan

  When I think of pretty much any programming language - like C, C++, PHP, SQL, JavaScript, Python, ActionScript, Haskell, Lua, Lisp, Java, etc - I'm like awesome I would love to develop a computer application using any of those languages. But when I think of web frameworks(I do mostly PHP) - like Cake, CI, Symfony, Laravel, Zend, Drupal, Joomla, Wordpress, Rails, Django, etc - I'm like god no. Why aren't there web frameworks that provide me with simple, fun and powerful constructs like a programming language?

• How to run software, that is not offered though package managers, that requires ia32-libs

  - by Onno

  I'm trying to install the Arma 2 OA dedicated server on a Virtualbox VM so I can test my own missions in a sandbox environment in a way that lets me offload them to another computer in my network. (The other computer is running the VM, but it's a windows machine, and I didn't want to hassle with its installation) It needs at least 2, and preferably 4GB of ram, so I thought I would install the AMD64 version of ubuntu 13.10 to get this going. 'How do you run a 32-bit program on a 64-bit version of Ubuntu?' already explained how to install 32bit software though apt-get and/or dpkg, but that doesn't apply in this case. The server is offered as a compressed download on the site of BI Studio, the developer of the Arma games. Its installation instructions are obviously slightly out of date with the current state of the art. (probably because the state of the art has been updated quite recently :) ) It states that I have to install ia32-libs, which has now apparently been deprecated. Now I have to find out how to get the right packages installed to make sure that it will run. My experience level is like novice-intermediate when it comes to these issues. I've installed a lot of packages though apt-get; I've solved dependency issues in the past; I haven't installed much software without using package managers. I can handle myself with basic administrative work like editing conf files and such. I have just gone ahead and tried to install it without installing ia32-libs through apt-get but to install gcc to get the libs after all. My reasoning being that gcc will include the files for backward compatibility coding and on linux all libs are (as far as I can tell) installed at a system level in /libs . So far it seems to start up. (I can connect with the game server trough my in-game network browser, so it's communicating) I'm not sure if there's any dependency checking going on when running the game server program, so I'm left with a couple of questions: Does 13.10 catch any calls to ia32libs libraries and translate the calls to the right code on amd64? If it runs, does that mean that all required libraries have been loaded correctly, or is there a change of it crashing later on when a library that was needed is missing after all? Is it necessary to do a workaround such as installing gcc? How do I find out what libraries I might need to run this software? (or any other piece of 32-bit software that isn't offered through a package manager)

• 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.
