Autotuner: How to speed up your Rails app
Ruby’s garbage collector is designed to be adaptable, scaling from short Ruby scripts to running apps that serve millions of requests per second.

Magic Numbers
1500 bytes is a bit out there as numbers go, or at least it seems that way if you touch computers for a living. It’s not a power of two or anywhere close, it’s suspiciously base-ten-round, and computers don’t care all that much about base ten, so how did we get here?
