      はじめに 「Just use Postgres」という言葉を初めて聞いたのは、いつだったか覚えていません。Twitter か Hacker News か、あるいは社内の Slack か。どこで聞いたにせよ、私の反応は決まっていました。「また極端なことを言う人がいる」と。 「それ、〇〇でもできますよ」——この手のフレーズはもう100回は聞いてきました。そして大抵の場合、その〇〇は専用ツールに置き換えられていきます。技術が専門分化していくのは自然な流れです。 全文検索なら Elasticsearch。時系列データなら InfluxDB。メッセージキューなら RabbitMQ。それぞれの分野に専門家がいて、専用のソリューションがあって、ベストプラクティスがあります。「とりあえず Postgres で」なんて、それは思考停止ではないか、と。でも、心のどこかで気になっていたんです。 www.mann

          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

DFINITY Status Update, New Year 2021I HAVE SOME EXCITING NEWS.On December 18, 2020, a crucial initial stage of Internet Computer blockchain’s decentralization occurred. This means that the Internet Computer’s mainnet now exists, and is hosted by standardized “node machines” tha

Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. Changes to the language Go 1.22 makes two changes to “for” loops. Previous

While we like to talk about how fast technology moves, internet time, and all that, in reality the last major new idea in software architecture was microservices, which dates to roughly 2015. Before that, cloud computing itself took off in roughly 2010 (AWS was founded in 2006); and Agile goes back to 2000 (the Agile Manifesto dates back to 2001, Extreme Programming t

Published: May 29, 2022 I recently got a copy of the book Compiling to Assembly from Scratch by Vladamir Keleshev, which details how to write a compiler for a subset of JavaScript to 32-bit ARM assembly code. The choice to use ARM assembly is mainly for its simplicity in comparison to x86. Keleshev elects to use TypeScript t

I would like to take some time to talk to WHY I believe now is a good time to start porting over Machine Lear
