• .NET Developer Basics – Recursive Algorithms

  Recursion can be a powerful programming technique when used wisely. Some data structures such as tree structures lend themselves far more easily to manipulation by recursive techniques. As it is also a classic Computer Science problem, it is often used in technical interviews to probe a candidate's grounding in basic programming techniques. Whatever the reason, it is well worth brushing up one's understanding with Damon's introduction to Recursion.

• Why am I having so many problems installing Ubuntu 13.10 alongside Vista?

  - by Matt Gazaway

  I am trying to setup my laptop to dual boot Ubuntu 13.10 and Windows Vista. I get as far as the drive table and it either freezes up or I get an error saying "unable to satisfy partition parameters" or something very similar. Now I just have a black screen with alternating indications that a request for cache data failed and something to do with a "write through". Any ideas on what I might be doing wrong?

• Why would you use data structures (ie Binary Trees, Linked Lists) in your jobs/side projects? [closed]

  - by Chris2021

  It seems to me that, for everyday use, more primitive data structures like arrays get the job done just as well as a binary tree would. My question is how common is to use these structures when writing code for projects at work or projects that you pursue in your free time? I understand the better insertion time/deletion time/sorting time for certain structures but would that really matter that much if you were working with a relatively small amount of data?

• Gnome-Shell 3.4 Themes not working in 12.04?

  - by CGriffitt

  Even themes advertised as Gnome-shell 3.4 compatible have graphical issues on Gnome-Shell 3.4. The main thing is that the text is black and nearly invisible, and the icons in the applications screen are crowded and in some cases overlapping. The themes did not do this before upgrade, and the default doesn't do it now. I am using user theme extension, and the themes I have tried are the Ambiance-Color set and London Smoke (both of which are advertised as 3.4 compatible).
