Building a “Simple” Distributed System – Formal Verification
In the last post , we described a protocol that should satisfy the requirements and invariants established in the first post . Today we will look at formal verification with TLA+. Formal verification is just another (niche) tool in the toolbox. Some tools require more skill than others to use. So

The Day I Fell in Love with Fuzzing
In 2007 I wrote a pair of modding tools, binitools , for a space trading and combat simulation game named Freelancer . The game stores its non-art assets in the format of “binary INI” files, or “BINI” files. The motivation for the binary format over traditional INI files was probably performance: it’s faster to load…

Outperforming everything with anything: Python? Sure, why not?
A 100 lines of Python code that substitute the compiler front-end for a specific computation. This shows that you don't need a “fast” compiling language to write efficient code. In fact, a compilation is only one of the multiple ways to achieve speed.

Compilers for Free
I’m fascinated by programming, and by metaprogramming in particular. When Ruby programmers talk about metaprogramming they usually mean programs that write programs , because Ruby has various features — like BasicObject#instance_eval , Module#define_method and BasicObject#method_missing — which make it possible to…
