これは超訳です。
CSSLintは「なんでこんなルールなんだ…」とイラっとすることが多いですけど、それぞれにそれなりに理由があります。まぁ勿論無視するべきなルールとかもあります。例えば見出し要素の再定義禁止とかはHTML5に対するCSSなら無理な話です。そんなわけでどんな理由なのかを簡単に訳しました。無視するかどうかは自分で決めましょう！
この訳はCSSLintと同じライセンスで提供されます。

重複処理 IEnumerableをそのまま使い回さない - Possible multiple enumeration of IEnumerable
IEnumerableをそのまま使うと、使う度に毎回変換される。遅延実行。 http://confluence.jetbrains.com/display/ReSharper/Possible+multiple+enumeration+of+IEnumerable
Assuming that GetNames() returns an IEnumerable, we are, effectively, doing extra work by enumerating this collection twice in the two foreach statements. If GetNames() results in a database query, you end up doing that query twice, while both times getting the same data.
ということで、特に複数回使う場合など適宜ToList()やToArray()しておく。

The introduction to Reactive Programming you've been missing
(by @andrestaltz)
If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.
Please consider using http://lygia.xyz instead of copy/pasting this functions. It expand suport for voronoi, voronoise, fbm, noise, worley, noise, derivatives and much more, through simple file dependencies. Take a look to https://github.com/patriciogonzalezvivo/lygia/tree/main/generative
float rand(float n){return fract(sin(n) * 43758.5453123);}
float noise(float p){
float fl = floor(p);
float fc = fract(p);

Survey of screenshot-based CSS testing tools
Currently considering https://github.com/webdriverio/webdrivercss
Core Goals:
- Can test in up-to-date versions of all major browsers
- Can test on up-to-date versions of all major OSes
- Can test in IE9 (because Bootstrap v4 will support IE9+)
- Don't want to have to setup/maintain our own cluster of VMs running all the necessary OSes (and all the versions of Windows)
- Workflow for management of reference/baseline/norm screenshots

Overview of Entity Component System (ECS) variations with pseudo-code
For background and further references see: Entity Component Systems on Wikipedia
ECS by Scott Bilas (GDC 2002)
entity= class: no logic + no data OR at most small set of frequently used data (ie position)component= class: logic + data
foreach entity in allEntities do
foreach component in entity.components do

A copy of the post on Singletons in Unity/C# as it appeared on UnityPatterns.com
Original post by David Laskey on UnityPatterns
As you develop in Unity, you’ll often find that it’s handy to have just single instances of certain objects. For example, let’s say we have a single GameObject, “MusicManager”, that’s in charge of our music. It might look like this:
using UnityEngine;
前提: 完成していて、比較的支持を集めていて、JavaScriptを中心にした書籍 (DOM APIよりは言語を中心とした内容)
追記: JavaScriptの入門書 #jsprimerを書いている
最初からES2015で学ぶことを前提にした初心者〜中級者向けのJavaScript本がなかったので書いてる。 ES2015でJavaScriptという言語のコア部分は大きく変わったので、それを前提とした内容にする予定。
