Consistent hashing, a guide & Go library

“Consistent hashing is deceptively simple yet very powerful, but I didn’t quite understand what it was till I sat down and worked it out for myself. Before I tell you about consistent hashing, you need to understand the problem we’re trying to solve…”

The basic concept is to write a routine that would take a five card poker hand and return it’s overall “value”. This is extremely valuable in any poker-related software, since the code will constantly be comparing various player’s hand with each other to determine the “winner”. Here is my concept on how I thought I could write a fast evaluator…”


My Top 100 Programming, Computer and Science Books: Part One

“I was recently interviewed by Fog Creek and one of the questions was about my favorite programming, coding and development books. I got very excited by this question as I’m a huge book nerd. And by a huge book nerd I mean I’m crazy about science, computer and programming books. Every few months I spend a day or two researching the latest literature and buying the most interesting titles. I could probably go on forever about my favorite books. I’ve so many.

I was so excited about this question that I decided to start a new article series here on catonmat about my top 100 programming, software development, science, physics, mathematics and computer books. I’ll do five books at a time as breaking huge tasks in tiny sub tasks is the easiest way to get things done…”
