「Postgres で試した？」と聞き返せるようになるまでもしくはなぜ私は雰囲気で技術を語るのか？ — Just use Postgres 読書感想文 - じゃあ、おうちで学べる
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

Show navigation Writing a high-performance JavaScript engine takes more than just having a highly optimising compiler like TurboFan. Particularly for short-lived sessions, like loading websites or command line tools, there’s a lot of work that happens before the optimising compiler even has a chance to start optimising, let alone having time to generate the optimised code. This is the reason why,

WebGPU is an upcoming Web API that gives you low-level, general-purpose access GPUs. I am not very experienced with graphics.

This got me far enough to

How a simple Linux kernel memory corruption bug can lead to complete system compromise
In this case, reallocating the object as one of those three types didn't seem to me like a nice way forward (although it should be possible to exploit this somehow with some effort, e.g. by using count.counter to corrupt the buf field of seq_file). Also, some systems might be using the slab_nomerge kernel command line flag, which disables this merging behavior. Another approach that I didn't look

There's been a lot of discussion recently about how "Safari is the new IE" (1, 2, 3, 4, 5). I don't want to rehash the basics of that, but I have seen some interesting rebuttals, most commonly: Safari is actually protecting the web, by resisting adding unnecessary and experimental features that create security/privacy/bloat problems. That is worth further discussion, because it's widespread, and w
