At Airplane, we collect observability data from our own systems as well as remote “agents” that are running in our customers’ infrastructure. The associated outputs, which include the standard “three pillars of observability” (logs, metrics, and traces) are essential for us to monitor our infrastructure and also help customers debug problems in theirs. Over the last year, we’ve made a concerted ef
This post is about why we need a coroutine package for Go, and what it would look like. But first, what are coroutines? Every programmer today is familiar with function calls (subroutines): F calls G, which stops F and runs G. G does its work, potentially calling and waiting for other functions, and eventually returns. When G returns, G is gone and F continues running. In this pattern, only one fu
In this post I will hopefully detail my entire home network. Some of this has been in separate posts explaining single items, but nowhere do I have all of the network in one post with all the changes since last year. Here is a full shot of the rack in my house. Its in a centrally located closet which happens to have a 2ft x 2ft chase into the attic, which is very handy for running network cables.
A common refrain is that threads can do everything that async/await can, but simpler. So why would anyone choose async/await? This is a common question that I’ve seen a lot in the Rust community. Frankly, I completely understand where it’s coming from. Rust is a low-level language that doesn’t hide the complexity of coroutines from you. This is in opposition to languages like Go, where async happe

A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
I recently realized stdout is much faster than stderr for Rust. Here are my findings after diving deep into this rabbit hole. I have been using the terminal (i.e. command-line) for most of my day-to-day things for a while now. I was always fascinated by the fact that how quick and convenient the command-line might be and that's why I'm a proponent of using CLI (command-line) or TUI (terminal user

Deprecation of formatting rules - ESLint - Pluggable JavaScript Linter
In ESLint v8.53.0, scheduled to be released on Friday, November 3, 2023, we will formally deprecate our formatting rules. Formatting rules are those rules that simply enforce code conventions around spacing, semicolons, string formats, etc. For a variety of reasons, which are discussed in this post, this is the right decision for ESLint going forward. However, to understand how we got here, it’s h
ごきげんよう！SmartHRプロダクトデザイナーのこぎそ（@kgsi)です。 SmartHRで2023年前半から開発に携わっていた「キャリア台帳」が、2024年2月8日についにリリースとなりました。 「キャリア台帳」は、SmartHRで収集した部署や役職、評価推移、スキルなど、タレントマネジメントに必要な従業員情報をまとめて確認できる機能です。今後タレントマネジメント領域を攻めていくSmartHRとして、欠けていたピースを埋める重要なプロダクトとなります。 さて、このプロダクトの開発にぼくは0->1フェーズから関わっていましたが、「初期開発における機能のスコープ決め」「リリース方式の選定」「開発とビジネス価値との接続」「初期フェーズでどのように関わるべきか」など...。プロダクトデザイナーとして、学びや気づきが大きいプロダクトでした。 この記事では、0->1フェーズにおけるプロダクトの開発

I've found that one of the best ways to understand a new concept is to start from the very beginning. Start from a place where it doesn't exist yet and recreate it yourself, learning in the process not just how it works, but why it was designed the way it was. This isn't a practical guide to async, but hopefully some of the background knowledge it covers will help you think about asynchronous prob

おとといフライデーのアルバム、2016年からのシングルを集めたものではあるのですが、なかなか感慨深い。 制作に参加しているミュージシャンが、トリプルファイヤー、マキタスポーツ、柴田聡子、NATSUMEN、Enjoy Music Club、Have a Nice Day!、バクバクドキン、パソコン音楽クラブ。更に作詞にはマンガ家の大橋裕之と映画監督の今泉力哉。 滅茶苦茶なんですが、何となく筋が通っているようにも思えるこの人の並び。 普通に音楽として滅茶苦茶面白いので、お勧めです。 ここでふと、AV女優の音楽活動について考える。 たとえば非アダルトな歌手がその後アダルト映画に入ってきた事例としては五月みどりや畑中葉子。 逆にアダルト映画やAV出身で歌も歌い、その後非アダルトなタレント業に参入したのは美保純や可愛かずみ、飯島愛。 そこらへんのメジャーなところはわかるのですが、じゃあ最初って誰よ、

Switching to Elixir
A few months ago I started a new job at a company that uses Elixir as its main language on the backend. I've never written a line of Elixir or Erlang before in my life, but I've heard a lot about it and Erlang is familiar because I've played around with Prolog for a bit. Thanks to the heavily Ruby-inspired syntax, Elixir was a synch to pick up. I might not be an expert on best practices, architect
