Computer science on paper

Blogger changed its interface and templates and when I tried to migrate I lost some of the settings I had on the old one, so I decided to use a new template. The new one it's a tribute to the good old days when we did computer science on paper. You just had to think carefully on the algorithm, write it down on paper, run it in your head again and then eventually get your turn to work on a computer to implement it (punch card or even keyboard version cause we were kind of short on computers). I think that being able to write down the algorithm and run through it really makes one understand it better, so actually in the year when I was a teaching assistant at University of Bucharest I asked many of my students to explain a few steps of their basic algorithms (back-tracking, divide et impera and the like) on paper in order to make sure they understood them and didn't just copy the project from a coleague. Some of them even liked it :)
