vimで使うキーの機能使用頻度と打ちやすさを整理してみました。 今回整理したのはnormalモードについてだけです。 機能の使用頻度と打ちやすさは、完全に個人の見解です。 キーボードによっても打ちやすさは変わると思います。
すべてのキーを網羅しているわけではありません。

/ Idempotent migration in MySQL example
Created
July 25, 2013 20:06
In MySQL, IF statements cannot exist outside of stored procedures. Therefore, to create an idempotent migration for MySQL it's necessary to wrap the migration in a stored procedure and execute that stored procedure against the database to perform the migration.

Chrome Firefoxでfocus出来ないと思ったら setTimeoutが居るらしい、理屈がよくわからん。
クリックイベントの最中にfocus()を他に移すのがNGなんだろうか

Quick virtualenv fix on Mountain Lion
It appears that Apple somehow broke Python in Mountain Lion, so even with the latest Command Line Tools and Xcode 4.4 virtualenv won't properly work. During virtual environment creation it will try to install easy_install inside /Library hierarchy. So let's give it a quick workaround. Let's install custom python into your $HOME-directory using pythonbrew!
Without the Apple Mac Developer account you won't even see the proper download link for the latest CL Tools and the old one won't work on ML. So here's the link: http://goo.gl/iBTXh. It points towards the Apple website so don't worry.

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。
