数字

let n1: f32 = 1.0f32;
let n2: isize = 0xF1A; // 16進数
let n3: isize = 0b11001; // ２進数

`git reflog` についてまとめてみる

reflog とは

reflog（参照ログ）とは HEAD やブランチ先端の動きの履歴
- 各個人のローカルリポジトリに存在
- ブランチの切り替え、新たに加えられた変更のプル、履歴の書き換え、あるいは単なる新規コミットの実行などを記録
git reflog で HEAD の移動履歴を、git reflog <ブランチ名> でそのブランチ先端が指していたコミットの一覧を確認可能
- HEAD@{5}: HEAD の五つ前の状態を示す

Activate MS Office 2019/2016 for macOS - Microsoft_Office_2019_VL_Serializer

Office 2019 above

2019-06-03

Note that Office2019 DO NOT support activate via simple copy/paste plist license file which is the simplest way to activate Office 2016. Fortunately, you can also use the VL Serializer tool, just install Office 2019 and Serializer, then run Serializer to activate.

	Watch out, os.IsExist(err) != !os.IsNotExist(err)

	They are error checkers, so use them only when err != nil, and you want to handle
	specific errors in a different way!

	Their main purpose is to wrap around OS error messages for you, so you don't have to test
	for Windows/Unix/Mobile/other OS error messages for "file exists/directory exists" and
	"file does not exist/directory does not exist"
