Pretende usar UUID como PK em vez de Int/BigInt no seu banco de dados? Pense novamente...

TL;TD

Não use UUID como PK nas tabelas do seu banco de dados.

eXtreme Go Horse (XGH) Process

Source: http://gohorseprocess.wordpress.com


1. I think therefore it's not XGH.
In XGH you don't think, you do the first thing that comes to your mind. There's not a second option as the first one is faster.

2. There are 3 ways of solving a problem: the right way, the wrong way and the XGH way which is exactly like the wrong one but faster.
XGH is faster than any development process you know (see Axiom 14).

Basic Snake HTML and JavaScript Game

Snake is a fun game to make as it doesn't require a lot of code (less than 100 lines with all comments removed). This is a basic implementation of the snake game, but it's missing a few things intentionally and they're left as further exploration for the reader.

Further Exploration

• Score
• When the snake eats an apple, the score should increase by one. Use context.fillText() to display the score to the screen

# Here's a contrived example of a LEFT JOIN using ARel. This is an example of
# the mechanics, not a real-world use case.

# NOTE: In the gist comments, @ozydingo linked their general-purpose ActiveRecord
# extension that works for any named association. That's what I really wanted!
# Go use that! Go: https://gist.github.com/ozydingo/70de96ad57ab69003446

I've been doing some work lately with JSON documents in PostgreSQL using jsonb columns. You can query these documents using a GIN index in PG, but the syntax can be a little cumbersome

SELECT "events".* FROM "events" WHERE "events"."body" @> '{"shift":{"user_id":2}}'

You have to construct the right side of the query as a JSON string, which is a bit annoying. So I wondered if I could adapt Arel to do the tedious stuff for me.
