Server Configuration in git

With git you can have anything versioned. You're used to version your code, which is a bunch of files. Your server configuration (on Linux) is also just a bunch of files, so it can be versioned as well.

The idea is simple: create a git repository in /etc/ and commit everytime you change any configuration of your server. Written in code:

cd /etc
git init
git add .

Nette\Object performance tests

I guess you already saw a short note Latency Numbers Every Programmer Should Know. I wanted to check how well Nette performs with its magic properties on Nette\Object.

You can see the testing code below together with raw output on my machine.

It show how much time in seconds it took to execute one million iterations of a particular action, thus it is also time in microseconds of one such call. You should compare it to null test, which execute empty iterations.
