55 seconds versus 20 seconds: this is the reason why I am switching from Chrome to Firefox for my automated tests.  I normally wouldn’t write a blog post about what browser I use for testing but I found the difference between the new Firefox and Chrome so striking that I thought I should write about it.

Yesterday I ported my first personal script from python2 to python3. This was just a simple, one file script that hacks together a way to track how long my kids are using the computer and log them off after they’ve hit a quota. The kind of thing that many a home … Read the rest
