Hi all,

You can find my this week's blog entry at
http://igniting.in/gsoc2014/2014/05/25/coding-things-up/ . I have created a
branch on launchpad for my work:
http://bazaar.launchpad.net/~igniting/maria/maria/revision/4211 . You can
give your suggestions/reviews either on this thread or as a comment on the
blog itself.

Regards
Anshu Avinash
