As a follow-up to the similar milestone reached for our WSL image a few months ago, I’m happy to share that Arch Linux now has a bit-for-bit reproducible Docker image! This bit-for-bit reproducible image is distributed under a new “repro” tag. The reason for this is due to one noticeable caveat: to ensure…
AI-assisted coding has become the norm and with tools like Cursor, GitHub Copilot, Claude Code, Codex, we are increasingly letting models touch our code. If you have used any of these tools in the past year, you have probably experienced something like this: you ask the model to fix a simple bug (perhaps a single…
I was chatting to a friend about my folding bike and I had the urge to write about it - because this falls in the category of “Things I wish I’d had decades ago”. And maybe I can encourage some others to try these wonderful devices. Note: I’m 3 months into a new job so blogging has taken a back seat to drinking from a…
three layers of system health, AI as cognitive system 3, what's expensive if agents make coding free, and the future of source code

A papyrus fragment of Homer’s epic The Iliad has been discovered inside the wrappings of Roman-era mummy . The mummy was found in a necropolis the ancient site of Oxyrhynchus (modern-day El-Bahnasa) in Egypt’s Minya Governorate. Archaeologists were able to remove the papyrus and identify the text as the “Index of…
Something I didn't understand for a while is that the process of turning row-oriented data into column-oriented data isn't a totally bespoke, foreign concept...
We trained an MLP that predicts 58 body shape parameters from 8 questionnaire inputs. The trick: a differentiable physics loss. Mass accuracy: 0.3 kg mean vs 3.9 kg for Ridge. No GPU at inference.
Benchmarks & Tips for Big Data, Hadoop, AWS, Google Cloud, PostgreSQL, Spark, Python & More...
LedgerStore became a case study for DynamoDB, and system design publications keep praising it to this day. But the design was abandoned 3 years after it went live.
An interactive exploration of how GPS works: from the speed of light and trilateration to the cheap clock problem and Einstein's relativity corrections.
The async/await saga is a story where each chapter solves the previous chapter's worst problem while introducing new structural costs. The sequential syntax that made async code readable also obscures the thing that matters: which operations actually depend on each other.
TL;DR: Don’t base your FPS calculations on a specific number of frames. Instead, maintain a rolling window of frames that happened during the last second. Use precise timers. Read on for more details.

If you agree that Apple itself was It’s hard to imagine a more orderly, confidence-inspiring, exciting-but-not-at-all-surprising, this-feels-right way to do this.

One of my favorite ways that creative people communicate is by “working with their garage door up,” to riff on a passage from Robin Sloan (below). This is the opposite of the Twitter account which mostly posts announcements of finished work: it’s Screenshot Saturday ; it’s giving a lecture about the problems you’re…
Tim Cook had an extraordinary run — and impeccable timing, both in terms of when he became CEO, and when he is stepping down.
every time i do, i feel bad for the poor person having to use it (especially if that person is me!). a plain list of bytes makes it hard to notice interesting things in the data. go ahead, try to find the single c0 in these bytes:
Nial – Knowledge work and artificial intelligence.
A practical guide to creating and maintaining powerful megamerge workflows in Jujutsu for faster, conflict-free development.
There is no need to update symmetric key sizes as part of the post-quantum transition, due to the details of how Grover's algorithm scales. Most authorities agree.

What nginx logs actually prove about AI traffic from ChatGPT, Claude, and Perplexity, plus why Google's AI crawlers leave a different signal than the others.
Explore how Shazam and song identification work through interactive visualizations: spectrograms, constellation maps, hash fingerprints, and time-offset matching.
Agents used to be a thing you talked to synchronously. Now they’re a thing that runs in the background while you work. When you make that change, the …
