First time in my life when whatever I do is open source and on GitHub. I remember when I left my first company, it was quite annoying to leave everything I contributed to behind me and not being able to look what it became from time to time. It is like coming back to your hometown, it is a place you know very well and quite hard to leave for ever.
I made a page for all the open source projects I work on. Most of them are my own, a couple of them contains the teaching I do, some others automate the publishing of the first one, some help me during my daily life, the last ones are Microsoft's one.
