In this document I am using Sass's SCSS syntax. You can choose to use the indented syntax in sass, if you prefer it, it has no functional differences from the SCSS syntax.
For Less, I'm using the JavaScript version because this is what they suggest on the website. The ruby version may be different.

| ニングポイントと感想です。 | |

| 今回のお題は MediaWiki への参照性能という事でまたPHPか! とは思いました | |

考えてみれば Model-View-Controller とか MVC ってよく聞くよね。実際どんなものか知ってる？ 抽象的に言うなら「オブジェクト情報の保持されるグラフィック・システム (つまり、ラスターではないグラフィック。ゲームとか) 上に構築された、表示系を中心としたアプリケーションにおいて、主要な機能どうしの関わりをうまく分離すること」とでも言おうか。もう少し深く考えを押し進めてみれば、これは当然、他のさまざまなアプリケーションにもあてはまる言葉 (bucket term ?) だ。
過去に多くの開発コミュニティが MVC による解決案を提供し、それによってよくあるユースケースにうまく対処し、地位を築くことができた。例をあげるなら、Ruby や Python コミュニティは Rails や Django を作り、MVC アーキテクチャを実現した。
For a while, I have felt that the following is the correct way to improve the mass assignment problem without increasing the burden on new users. Now that the problem with the Rails default has been brought up again, it's a good time to revisit it.
When creating a form with form_for, include a signed token including all of the fields that were created at form creation time. Only these fields are allowed.
To allow new known fields to be added via JS, we could add:
| Security Alert - Please reset your npm registry account | |
| ================================================== | |
| The security of the npm registry has just been upgraded. This corrects a known | |
| flaw which led to the leakage of the password_sha and salt fields. The good | |
| news is that the leak is plugged. The bad news is that it existed for quite a | |
| while. | |
| tl;dr |
