Docker for Mac の Volumeマウントの遅さについて Docker for Mac は正式版になる以前からローカルファイルシステムをマウントした際の、read/writeの遅さが指摘されていた。特に write 側は絶望的なベンチマークがいつも示されていた。 私も、2017年10月に以下の記事でその当時のベンチマークをしている。 MacおよびWinにおけるDocker環境のベンチマーク結果まとめ(2017-10-23現在) このまま改善されないまま進むんではないかと悲観的に見ていたのだが、 18.03.0-ce の rc1 のリリースノートに以下のように Support NFS Volume sharing という記述があったのに気がついた。 ### 2018-02-27 18.03.0-ce-rc1-mac54 "18.03.0-ce-rc1-mac54" * Upgra

When I first started trying to understand the memory allocator of Go, it was maddening. Everything seemed like a mystical black box. As almost every technical wizardry is hidden beneath abstractions, you need to peel off those layers one by one to understand it. In this blog post, we will exactly do that. Do you want to learn everything about Go memory allocator? You’re reading the right article.
Intro ECMAScript の Private Class Field の仕様策定と各ブラウザの実装が進んでいる。 これにより、従来の JS にはなかった Class の Private フィールドが使えるようになる。 提案されている構文や、挙動について解説する。 Class Field Declaration まず前提として、現状の Class の フィールドはコンストラクタで定義する必要がある。 例えば count フィールドを持つ Counter クラスを定義した場合、以下のようになる。 class Counter { constructor() { this.count = 0 } increment() { this.count ++ } display() { console.log(this.count) } } const c = new Counter() c.in
Black-box testing is a method of software testing that examines the functionality of an application without peering into its internal structures or workings.
