You there? I have a question about *programming*  that I think you might be able to answer.

(Type 'sure', 'pass', or 'busy'.)
(03:37:27 AM) k: sure
(03:37:28 AM) vark: (From Semyon S./25/M/St.Petersburg,Russia)
What is better git or svn?

(Type 'pass' to skip, 'flag' if this question is inappropriate, or 'more' for options.)
(03:39:55 AM) k: Semyon: Git is definitely better. Subversion proposal for version control is deprecated. I've written myself an article about some differences between Git and Subversion here: http://kspg.com.ar/blog/posts/8/
