60年代生まれのAlgol 68、最新GCCに初上陸：C++20デフォルト化と同日リリースの狙い | XenoSpectrum
GNUコンパイラコレクション（GCC）16.1が2026年4月30日にリリースされ、C++のデフォルト方言をGNU C++17からGNU C++20へ切り替えた。この変更は`-std`を指定せずにビルドしている全C++プロジェクトに影響する。同リリースには1960年代に設計されたAlgol 68の実験的フロントエンド`ga68`も追加され、最新言語規格と古典言語の支援が並行して進む異色の構成になっ...

holy shit.
Git 2.54 introduces a new way to define hooks: in your configuration files. Instead of placing a script at .git/hooks/pre-commit, you can now write: [hook "linter"] event = pre-commit command = ~/bin/linter --cpp20 The hook.<name>.command key specifies the command to run, and hook.<name>.event specifies which hook event should trigger it. Since this is just configuration, it can live in your per-user ~/.gitconfig, a system-wide /etc/gitconfig, or in a repository’s local config. That makes it straightforward to define a set of hooks centrally and have them apply everywhere. Even better, you can now run multiple hooks for the same event. If you want both a linter and a secrets scanner to run before every commit, you can configure them independently: [hook "linter"] event = pre-commit command = ~/bin/linter --cpp20 [hook "no-leaks"] event = pre-commit command = ~/bin/leak-detector Git will run them in the order it encounters their configuration. The traditional hook script in $GIT_DIR/hooks still works, and runs last, so existing hooks are unaffected. You can see which hooks are configured (and where they come from) with git hook list
