Google日本語入力で簡単に矢印記号を入力する

Google日本語入力で「z」に続いて vi のカーソル移動のコマンドに対応する h, j, k l を入力すると,vi でカーソルが移動する方向と対応する矢印記号に変換される. 具体的には, z h : ← z j : ↓ z k : ↑ z l : → のように変換される.便利.

[Git] pushされた内容を反映

いろいろな場所で仕事をするので git の bare なリポジトリを一つサーバに置き、 変更を push するようにしている。 たまに、サーバ上でもコードを変更したい時ががあるが、 push された内容がリポジトリの作業コピーに反映されていない。 push された内容を自身の作業コピーに反映させるには、 % git reset –hard とすれば良いよう。
