As you can guess my name is Guy Rutenberg, and I live in Tel Aviv, Israel. I look at the blog that you’re reading as a self-reference tool and a way to share with others useful and not so useful things I’ve wrote or found.
I’ve studied a B.Sc in Mathematics and Computer Science and an M.Sc in Mathematics from Tel Aviv University (my thesis supervisor was Prof. Noga Alon).
I am a proponent of open source software and contributed code to quite a few projects along the years, in a wide variety of languages and fields.
From time to time, when an interesting offer comes along, I do freelance jobs. If you have something you I can help you with, please contact me.
