I believe that our life is useful in one way or another and there are more important things than earning a lot of money. Self-development is one of those things and we can learn from each other - therefore I support the open source solutions. How could I end up on the Microsoft platform? Actually, I started here, nowadays I run "only" databases on Windows (but I'm playing around with web hosting). And I personally do believe that Windows 10 will be open source or there won't be a popular Windows 10.
I'm a big fan of T-SQL and PowerShell and also interested in C#, just unable to get time to learn it :)
I have a nice blog in Hungarian, occasionally with English posts at
