written on June 12, 2025 There is currently an explosion of people sharing their experiences with agentic coding. After my last two posts on the topic, I received quite a few questions about my own practices. So, here goes nothing. Preface For all intents and purposes, here’s what I do: I predominently use Claude Code with the cheaper Max subscription for $100 a month 1. That works well for severa

November 1, 2023 Hello! I’m slowly working on explaining git. One of my biggest problems is that after almost 15 years of using git, I’ve become very used to git’s idiosyncracies and it’s easy for me to forget what’s confusing about it. So I asked people on Mastodon: what git jargon do you find confusing? thinking of writing a blog post that explains some of git’s weirder terminology: “detached HE
Fish 4.0: The Fish Of Theseus
About two years ago, our head maintainer @ridiculousfish opened what quickly became our most-read pull request: #9512 - Rewrite it in Rust Truth be told, we did not quite expect that to be as popular as it was. It was written as a bit of an in-joke for the fish developers first, and not really as a press release to be shared far and wide. We didn’t post it anywhere, but other people did, and we go

Highlights from Git 2.54
The open-source Git project just released Git 2.54 with features and bug fixes from over 137 contributors, 66 of them new. We last caught up with you on the latest in Git back when 2.52 was released. To celebrate this most recent release, here is GitHub’s look at some of the most interesting features and changes introduced since last time. 💡 Since the last Git release we wrote about was Git 2.52,
Tweag has been working on a GHC WebAssembly backend for some time. Recently, the WebAssembly backend merge request has landed in GHC, and is on course to appear in the upcoming 9.6 release series.

Hypershell: A Type-Level DSL for Shell-Scripting in Rust | Context-Generic Programming
Discuss on Reddit, Lobsters, and Hacker News. Summary I am thrilled to introduce Hypershell, a modular, type-level domain-specific language (DSL) for writing shell-script-like programs in Rust. Hypershell is powered by context-generic programming (CGP), which makes it possible for users to extend or modify both the language syntax and semantics.

October 1, 2024 Yesterday I was thinking about how long it took me to get a colorscheme in my terminal that I was mostly happy with (SO MANY YEARS), and it made me wonder what about terminal colours made it so hard. So I asked people on Mastodon what problems they’ve run into with colours in the terminal, and I got a ton of interesting responses! Let’s talk about some of the problems and a few pos
Notes by djb on using Fil-C (2025) I'm impressed with the level of compatibility of the new memory-safe C/C++ compiler Fil-C (filcc, fil++). Many libraries and applications that I've tried work under Fil-C without changes, and the exceptions haven't been hard to get working. I've accumulated miscellaneous notes on this page regarding usage of Fil-C. My selfish objective here is to protect various

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,
The Unix shell is over 50 years old, but it still defines how programmers use their computers. We type a few words in a terminal, and milliseconds later an ephemeral factory comes online: the Unix pipeline.

Since I was unable to travel for a couple of years during the pandemic, I decided to take my new-found time and really lean into Rust. After writing over 100k lines of Rust code, I think I am starting to get a feel for the language and like every cranky engineer I have developed opinions and because this is the Internet I’m going to share them. The reason I learned Rust was to flesh out parts of t
What’s New in Emacs 31.1? Emacs 31.1 adds a slew of quality-of-life features. It retires its quirky unexec dumper; there are general improvements to tree-sitter, including a much-wanted auto-installer for grammars; and much more. Emacs 31.1 is finally out! Unlike earlier Emacs versions, there is not a singular big-bang feature in this release. From what I could gather, the new garbage collector wa

Edge AI Just Got Faster
When Meta released LLaMA back in February, many of us were excited to see a high-quality Large Language Model (LLM) become available for public access. Many of us who signed up however, had difficulties getting LLaMA to run on our edge and personal computer devices.

OpenBSD is an operating system that's famous for its focus on security. Unfortunately, OpenBSD leader Theo states that there are only 7000 users of OpenBSD. So it's a very small but elite group, that wields a disproportionate influence; since we hear all the time about the awesome security features these guys get to use, even though we usually can't use them ourselves.

Since the latest source code is always available on GitHub, many have already picked up later patch versions (there are mor
How to create IAM roles for deploying your AWS Serverless app | Serverless First
Getting IAM permissions right is one of the hardest parts about building serverless applications on AWS. Many official tutorials and blog posts cop out of giving you the full details on how to set up IAM, preferring something vague like “ensure you use least-privilege permissions when creating this role”. Or worse, they give you a wide open wildcard or admin-level example policy with a “don’t use

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
Defending new vectors: Threat actors attempt SQL Server to cloud lateral movement | Microsoft Security Blog
Microsoft security researchers recently identified a campaign where attackers attempted to move laterally to a cloud environment through a SQL Server instance. This attack technique demonstrates an approach we’ve seen in other cloud services such as VMs and Kubernetes cluster, but not in SQL Server. The attackers initially exploited a SQL injection vulnerability in an application within the target

My thoughts on writing a Minecraft server from scratch (in Bash) For the past year or so, I've been thinking about writing a Minecraft server in Bash as a thought excercise. I once tried that before with the Classic protocol (the one from 2009), but I quickly realized there wasn't really a way to properly parse binary data in bash.

PowerShell: the object-oriented shell you didn’t know you needed | Chris Warrick
PowerShell is an interactive shell and scripting language from Microsoft. It’s object-oriented — and that’s not just a buzzword, that’s a big difference to how the standard Unix shells work. And it is actually usable as an interactive shell. Getting Started PowerShell is so nice, Microsoft made it twice. Specifically, there concurrently exist two products named PowerShell: Windows PowerShell (5.1)
