Today
- The best kept secret at the frontier of system programming right now is the Linux 4.18+ (c. 2018) concept of restartable sequences or rseq for short. They allow you to create thread-safe data structures without locks or atomics which scale to microprocessors with many cores....
- Having used Claude Code for a few months now, I have noticed how software development has changed for me. I write a lot less code, but I spend more time understanding and testing the code Claude has written. The proportions … Continue reading →...
- Drama about the pricing of AI models, countless npm vulnerabilities and Google I/O that at this point should be rebranded to Google AI. This is a short summary of the past month in software. Most of the news from these categories I entirely ignore, so I prepared for you a list...
- Gradient shaderPlanted: May 2026Status: seedIntended Audience: Creative coders and front-end developers with a basic understanding of WebGL shaders.How to create an organic gradient animation using a WebGL shader. If you're new to shaders, check out this note. What we'll make:...
- There are only two ways to use LLMs in a computer program: as part of a pipeline, or as an agent. In other words, either you express the control flow of the program in code, or you give a LLM tools and allow it to manage the control flow itself1.
This week
- Today we're excited to announce Agent Builder — a space for teams to build and share agents. Think about Agent Builder as a composable agent studio: Developers......
- My colleague Chris Griffith, with whom I collaborated to put The Effects of Nuclear Weapons, Third Edition (1977) online, is also a spaceflight enthusiast (and an urban trails hiker: check out his new book!). He recently asked me how I would mark up a table with a split diagonal...
- To conclude with my SQLAlchemy 2 in Practice series, this article contains the solutions to all the exercises. If you'd like to support my work, I encourage you to buy this book, either directly from my store or on Amazon. Thank you!...
- At the GOTO Conference in Copenhagen in 2025, Kent Beck and I spent some time on stage talking and answering questions from the audience - a format I refer to as “two old geezers on a park bench”. We talk about our experiences with LLM-augmented programming (at that point -...
- Dropped this morning by the Vatican: Magnifica Humanitas of His Holiness Pope Leo XIV on Safeguarding the Human Person in the Time of Artificial Intelligence. This is a very interesting …
- Anthropic are strongly rumored to be about to have their first profitable quarter. Stories are circulating of companies surprised at how expensive their LLM bills are becoming from usage by …
- Vibe coding has significantly accelerated software prototyping but AI agents frequently recommend insecure configurations, creating security problems. Gautam Koul, Lucian Moss, Neil Drew-Lopez, and Daberechi Ruth Edeokoh share their experience while building applications for...
- Birgitta Böckeler finishes her post on sensors for coding agents by examining the role of a test suite as a regression sensor, focusing on the role mutation testing can play. more…...
- 27 May, 2026 One of the things I like best about blogs is that posts stick around (or at least they should). I enjoy scrolling through historic posts of bloggers and reading about what they were thinking about 1, 5, or even 10 years ago—if I'm lucky. I've noticed that my most...
- Very recently, I was hunting for a new TV show and clicked on Apple TV, drawn in by the buzz surrounding Margo Has Money Troubles. I launched the first episode and got hooked by the new intro logo. It caught my eye because it felt weirdly alive. There was a specific, imperfect...
- There are a bunch of JavaScript animation libraries out there, and you might have wondered whether there’s a performance cost compared to traditional CSS transitions and keyframe animations. In this blog post, we’ll compare the same animation across several different strategies...
- Build, customize, and deploy production agents that reason, execute code, and manage files inside secure Linux sandboxes as a single API call....
- How I wrangled millions of raw vessel position reports into a structured H3 grid — and what that grid makes possible....
- Algorithmic and optimization playtime...
- High end NVIDIA cards, and the server and power needed to run them, cost a lot of money, especially if you plan to reach enough VRAM to run massive models. The alternative, so far, has been Apple hardware, or the DGX Spark that, even if severely limited because of memory...
- Starting more agents is easy now. However, more agents running doesn't mean more of you available - your cognitive bandwidth doesn't parallelize. All the judgement to actually steer them and merge the code they write into the codebase still has to route through exactly one...
- Massive demand for the role at Google, OpenAI, and Anthropic. The latest version of the FDE role looks like the consultant / solution architect role done by many early-junior engineers....
Last week
- The current AI pricing was always going to go away. It just doesn’t make sense. Microsoft canceled internal Claude Code licenses this week (for whatever reason, even if it’s because they integrated it), Uber blew its entire 2026 AI budget in four months, and GitHub is dropping...
- Blog About Moonbound Shop This is a post from Robin Sloan’s lab blog & notebook. You can visit the blog’s homepage, or learn more about me. May 21, 2026 Justin Duke, he of Buttondown, writes: Almost all of [our recent spike in growth] I attribute to LLMs. We ask people when they...
