  • You know that thing you do, where you write some code and then realize you need a main function to execute it? And then you write your main function, but it’s not really your main function, it’s a bunch of half commented test code to make sure that the important code works?

    Do that in a unit test, and when you’re done testing that particular piece, add some assertions and move on to the next piece of functionality. Boom, test driven development.





  • Once upon a time I was installing Linux on a tiny little laptop, whose brand name I’ve forgotten. It was probably a Lenovo. Anyway, it was extremely difficult to install anything on it, and they went to great lengths to make sure no one would be able to install Linux on it. I spent an entire day messing around with the grub terminal, and began to suspect that it had a built-in cut off for the USB port during boot. I think I saw some log output to that effect, but I couldn’t find any way to disable it. After some thought, I got back in grub, unplugged the USB stick that I was installing Linux from, and plugged it back in. The laptop detected and mounted the external drive and I tried to install again.

    Worked perfectly.
