Weird Lexical Syntax
I just learned 42 programming languages this month to build a new syntax highlighter for llamafile. I feel like I'm up to my eyeballs in programming languages right now. Now that it's halloween, I thought I'd share some of the spookiest most surprising syntax I've seen. The languages I decided to support are Ada, Assembly, BASIC, C, C#, C++, COBOL, CSS, D, FORTH, FORTRAN, Go, Haskell, HTML, Java,

Posted on Tuesday, April 2, 2024. Updated Wednesday, April 3, 2024. Introduction Andres Freund published the existence of the xz attack on 2024-03-29 to the public oss-security@openwall mailing list. The day before, he alerted Debian security and the (private) distros@openwall list. In his mail, he says that he dug into this after “observing a few odd symptoms around liblzma (part of the xz packag

I’ve become convinced that “little languages”—small languages designed to solve very specific problems—are the future of programming, particularly after reading Gabriella Gonzalez’s The end of history for programming and watching Alan Kay’s Programming and Scaling talk. You should go check them out because they’re both excellent, but if you stick around I’ll explain just what I mean by “little lan

Notable changes Add support for externally shared js builtins By default Node.js is built so that all dependencies are bundled into the Node.js binary itself. Some Node.js distributions prefer to manage dependencies externally. There are existing build options that allow dependencies with native code to be externalized. This commit adds additional options so that dependencies with JavaScript code

redbean 2.0 release notes
redbean is a webserver in a zip executable that runs on six operating systems. The basic idea is if you want to build a web app that runs anywhere, then you download the redbean.com file, put your .html and .lua files inside it using the zip command, and then you've got a hermetic app you can deploy and share. I introduced this web server about a year ago on Hacker News, where it became the third
Flipping Pages: An analysis of a new Linux vulnerability in nf_tables and hardened exploitation techniques
This blogpost is the next instalment of my series of hands-on no-boilerplate vulnerability research blogposts, intended for time-travellers in the future who want to do Linux kernel vulnerability research. Specifically, I hope beginners will learn from my VR workflow and the seasoned researchers will learn from my techniques. In this blogpost, I'm discussing a bug I found in nf_tables in the Linux
September 12, 2024 I wrote about how much I love fish in this blog post from 2017 and, 7 years of using it every day later, I’ve found even more reasons to love it. So I thought I’d write a new post with both the old reasons I loved it and some reasons. This came up today because I was trying to figure out why my terminal doesn’t break anymore when I cat a binary to my terminal, the answer was “fi

オンプレで実行されているバッチ (cron + shell script) をAWS Lambdaに移植する方法 - エムスリーテックブログ
こんにちは、エンジニアリンググループの大和です。 弊社ではエンジニアリンググループ全体で継続して脱オンプレを進めており、これまでに多くのDBやサーバを停止してきました。 www.m3tech.blog また、直近ではコンシューマチームでの取り組みが紹介されています。 www.m3tech.blog 私が所属するマルチデバイスチームでも、前年度までに管理しているサービスのオンプレDBおよびサーバを廃止しました。 コンシューマチームの記事でも説明されていますが、脱オンプレではサーバアプリケーションとDBだけを移行するだけでは足りず既存のバッチや監視周り等含めて移行する必要があります。 この記事では、そのうちcronでshell scriptを実行しているような簡単なバッチをAWS上に移行する方法を紹介します。 構築するシステムの構成 インフラ構築 VPCに紐付けるLambdaの設定 Lambd
