This tweet has to have been the most popular thing I have ever said. At time of posting it has gained 80 retweets, 25 favourites and many replies/questions. Work recently bought me a new workstation, so the 1st thing I always do is to dual boot with Ubuntu. Some might consider me an edge case user. [...]

Adding extra fields to FOSUserBundle / SonataUserBundle
October 3rd, 2012
No Comments
