Some time ago i bought a classical C manual: “The C Programming Language” by Kernighan and Ritchie. Good read.

Today i was implementing “fold” from the book exercises. It is not coming easy this time. I have some ideas on how to progress, but right now i am stuck and in the bar somewhere in Williamsburg. Obviously trying to reach Ballmer’s Peak.

Two things for tomorrow:

• Need automated testing;
• Algorithms matter;

Since no finished code on hands today – i am not posting it here.

P.S. did you know that bash can repeat last executed command with all parameters if you run `!!`?
