INTRO

Concurrency is a domain I have wanted to explore for a long time because the locks and the race conditions have always intimidated me. I recall somebody suggesting concurrency patterns in golang because they said "you share the data and not the variables".

Amused by that, I searched for "concurrency in golang" and bumped into this awesome slide by Rob Pike: https://talks.golang.org/2012/waza.slide#1 which does a great job of explaining channels, concurrency patterns and a mini-architecture of load-balancer (also explains the above one-liner).

Let's dig in:

Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional

Example

Idiomatic React Testing Patterns

Testing React components seems simple at first. Then you need to test something that isn't a pure interaction and things seem to break down. These 4 patterns should help you write readable, flexible tests for the type of component you are testing.

Setup

I recommend doing all setup in the most functional way possible. If you can avoid it, don't set variables in a beforeEach. This will help ensure tests are isolated and make things a bit easier to reason about. I use a pattern that gives great defaults for each test example but allows every example to override props when needed:

概要

redcaretとgithub-markdownの違い

両者のソースは割りと似ている(github-markdownがredcarpetを元にしたのか、あるいは両者のもとになったC実装があるとかかな)

オプションについて

github-markdownは、redcapetの提供するオプションの一部をデフォルトで有効化します。 (ちなみに有効化するオプションを選ぶAPIはない模様。用途を考えるとそれで正しいが)

★がついているのが有効化されるもの。gfmモード(.render_gfmメソッド)の場合のみ、★★も有効化される。
