A Review of Perl 6 (Raku) – Evan Miller
By Evan Miller August 13, 2017 [ Update, Feb. 5, 2020: Perl 6 is now called Raku. I’ve updated the review title, but left the review body intact. ] “Man is amazing, but he is not a masterpiece,” he said, keeping his eyes fixed on the glass case. “Perhaps the artist was a little mad…” —Joseph Conrad, Lord Jim Perl 6 reminds me of my uncle’s Ph.D. dissertation. For the first five years, we would ask
Evaluating Splatoon’s Ranking System – Evan Miller
As you can see there is a bias in place for players at lower ranks, which tends to push players up from the starting rank, which is C−. That bias disappears once you become a “B” player, at which point the reward for victory equals the penalty for defeat. The system is designed so that, starting with a rank of B, you’ll need more victories than defeats to keep getting promoted. (The reward or pena
Why I’m Betting on Julia – Evan Miller
By Evan Miller January 23, 2014 Translations: Japanese The problem with most programming languages is they’re designed by language geeks, who tend to worry about things that I don’t much care for. Safety, type systems, homoiconicity, and so forth. I’m sure these things are great, but when I’m messing around with a new project for fun, my two concerns are 1) making it work and 2) making it fast. Fo
How Not To Sort By Average Rating
By Evan Miller February 6, 2009 (Changes) Translations: Dutch Estonian German Russian Ukrainian PROBLEM: You are a web programmer. You have users. Your users rate stuff on your site. You want to put the highest-rated stuff at the top and lowest-rated at the bottom. You need some sort of “score” to sort by. WRONG SOLUTION #1: Score = (Positive ratings) − (Negative ratings) Why it is wrong: Supp
Statistical Formulas For Programmers – Evan Miller
By Evan Miller May 19, 2013 Being able to apply statistics is like having a secret superpower. Where most people see averages, you see confidence intervals. When someone says “7 is greater than 5”, you declare that they’re really the same. In a cacophony of noise, you hear a cry for help. Unfortunately, not enough programmers have this superpower. That’s a shame, because the application of statist
The Mathematical Hacker – Evan Miller
By Evan Miller November 16, 2012 (Corrections) The programming profession is blessed with a number of gifted essayists. Today I will pick on three of my favorites — Eric Raymond, Paul Graham, and Steve Yegge — because they all seem to disagree about why (and whether) mathematics is relevant to the practicing programmer. Their attitudes might be summarized as: Eric Raymond: Mathematics is unnecessa
Why I Program in Erlang – Evan Miller
Why I Program In Erlang By Evan Miller October 20, 2012 Translations: Urdu Erlang is a twenty-five-year-old programming language that has yet to win a popularity contest, and almost certainly will never win any medals for speed, let alone any tiaras for syntactic beauty. The language is slow, awkward, and ugly. Refactoring Erlang code is a pain. Yet for almost five years, I have spent a large chun
