想定読者

• linuxに関する基本的な知識があるソフトウェアエンジニアもしくはヘビーユーザで、Quest 3のlinuxをGUI環境で使いたい人
• apkのインストールとか説明しませんが、Quest 3に入れたやつは、アプリ一覧からカテゴリでUntrusted Sourcesみたいなのを選ぶと出てきます
• termuxの上にlinux distroを載せるのは、遅いのでやりません（下記ベンチマーク参照）。prefixed-rootだろうがシングルユーザだろうがmusl libcだろうが我々なら大丈夫だ！
• linuxアプリのインストールは特記事項ない限り省略します。勝手にpkg installとかして

Create a file named user userconf (or userconf.txt) containing the following:
pi:$6$c70VpvPsVNCG0YR5$l5vWWLsLko9Kj65gcQ8qvMkuOoRkEagI90qi3F/Y7rm8eNYZHW8CY6BOIKwMH7a3YYzZYL90zf304cAHLFaZE0
Place userconf (or userconf.txt) plus an empty file named ssh (or ssh.txt) in the BOOT (FAT32) partition of the SD card.
Insert the SD card in the Raspberry Pi and it should boot with access to user 'pi' (password : raspberry) via SSH.

Real World 業務 Rust

前置き

これは

• 多人数の開発で
• Rustに不慣れな人間もかなり混ざってて
• 富豪的プログラミングが可能な Web 開発で
• コードオーナー不在で

Commit Message Format

This specification is inspired by and supersedes the [AngularJS commit message format][commit-message-format].

We have very precise rules over how our Git commit messages must be formatted. This format leads to easier to read commit history.

Each commit message consists of a header, a body, and a footer.

Virtual DOM and diffing algorithm

There was a [great article][1] about how react implements it's virtual DOM. There are some really interesting ideas in there but they are deeply buried in the implementation of the React framework.

However, it's possible to implement just the virtual DOM and diff algorithm on it's own as a set of independent modules.
