Here you will find technical blogposts. These often require some knowledge of some programming language.
Some of the topics covered here will be tools, tricks, hacks or experiments.
Rails Testing I have often been told and red not to test the database. To avoid useless round trips and that my tests should be testing the code, not the database. That is the key to fast testing. But how fast exactly does this change? I took it upon myself to figure it out. I wanted to know the affects of slow vs fast testing and measure it.

Ruby Shift vs Multiply Having a background in hardware development, I always assumed some operations were trivial and more efficient done some way rather than another.
One of those operations for example was the usage of shifting by 1 instead of multiplying by 2. The reason it would be more effective is due to the CPU complexity of multiplying by two as opposed to shifting bits which is equivalent to just selecting whatever is high on the clock cycle. »
