• Is Collections.shuffle suitable for a poker algorithm?

  - by Kovu

  Hi, there is a poker-system in java, that uses Collections.shuffle() on all available cards before the cards are dealt. So a collection of 52 cards 2-9, J, Q, K, A in 4 types. After that we Collections.shuffle(). The problem is, that it seems (until now we didn't have big statistic, it's possible that we only see a lot of statistic inferences), that the algorithm is VERY unclearly. So, is Collections.shuffle() okay for a poker algorithm?

• Android Eclipse test projects cannot be used with a project being built in an Android build tree

  - by orospakr

  An Android Java project placed in a git repository and built in an Android tree in /packages/apps needs to have the project files located at the root of the git repository. This is problematic for creating a complementary Test project, which should ideally be included in the same git repository so commits are atomic for both code and tests. Eclipse gets very unhappy if you include the Test project as a subdirectory. Is there an appropriate approach for dealing with this other than creating a second repository?

• Is there any reason to prefer UTF-16 over UTF-8?

  - by Oak

  Examining the attributes of UTF-16 and UTF-8, I can't find any reason to prefer UTF-16. However, checking out Java and C#, it looks like strings and chars there default to UTF-16. I was thinking that it might be for historic reasons, or perhaps for performance reasons, but couldn't find any information. Anyone knows why these languages chose UTF-16? And is there any valid reason for me to do that as well?

• Amazon EC2 Development Stack

  - by sirmak

  I want to use EC2 for some reasons and EC2 provides both windows and linux deployments, but linux is much cheaper (linux reserved instances are approx. %63-%85 price of windows ones and spot instances are %50 cheaper for linux). I need a type safe lang and mainstream platform and I prefer to use .net/c# stack (but not mono for some reasons), but in this situation java seems a better fit for the future (when ec2 instance counts begin to increase). So, is it worth to use .net ? best regards,
