My spicy take on vibe coding for PMs
I shared this internally at Meta in response to a deluge of clout-chasing posts celebrating PMs landing prod diffs. The response was positive and the message generalizes, so here we are on the open www. PMs shouldn’t waste time landing … Continue reading →

The IBM-ification of Google?

There's no point at which turning your brain off will work
In early 2025, I started seeing people turn off their brain as they use LLMs 1 . They would have an LLM take an action (summarize text, write some code, etc.), and just assume that it worked 2 . This generally didn't work in early 2025 and the result was often quite silly.

Build your own Dial-up ISP with a Raspberry Pi
Last year my aunt let me add her original Tangerine iBook G3 clamshell to my collection of old Macs1. It came with an AirPort card—a $99 add-on Apple made that ushered in the Wi-Fi era. The iBook G3 was the first consumer laptop with built-in Wi-Fi antennas, and by far the cheapest way to get a computer onto an 802.11…

You Want to Visit the UK? You Better Have a Google Play or App Store Account
New immigration rules for the UK are being enforced starting February 2026. This means citizens of 85 additional countries (including the USA and European countries) will need an Electronic Travel Authorisation (ETA) to visit, even for tourism. Luckily, you can apply (and pay) digitally. Unfortunately, the government…

Maybe comments should explain 'what' (2017)
People say “Comments should explain why, not what.” I feel like starting a flame war today so I’m going to argue that comments should explain ‘what’ too. Please don’t use this as justification to write bad code, okay? Okay. First of all, why shouldn’t comments explain ‘what’? If you need comments to explain what’s…

CVE-2026-31431: Copy Fail vs. rootless containers
In the previous post about SELinux MCS and GitLab runners, I briefly mentioned CVE-2026-31431 (“Copy Fail”) as a motivating example for per-job VM isolation. After that post went out I spent the weekend setting up a lab to actually run the exploit, trace it at the syscall level, and verify that the rootless Podman…

Alternate clock designs and time systems
A day has 24 hours in it. That's 1,440 minutes or 86,400 seconds. If you wonder why Americans don't understand the need for using the metric system then ask yourself why you use this inconsistent time measurement system.

Building a 24-bit arcade CRT display adapter from scratch
In November, my friend and fellow Recurser, Frank , picked up an arcade machine for the Recurse Center . We call it the RCade. He wanted to leave the original CRT in - which I think is a great choice! - and drove it off of a Raspberry Pi. Eventually we wanted to move to a more powerful computer, but we needed a way to…

Whatever Happened to Fire Escapes
[Note that this article is a transcript of the video embedded above.] The idea is simple: If there’s a fire in a tall building that blocks the main stairwell, people need an alternative way to evacuate, preferably one that is somewhat protected or at least far away from where the fire is happening

Run OpenBSD on DigitalOcean for $4/month
My homepage now runs on OpenBSD with httpd(8) and Let's Encrypt via acme-client(1) . I previously hosted it on GitHub Pages and then eventually moved to Cloudflare Pages because both options were free and easy. Free and easy is cool, and I understand that writing software full-time leaves us wanting absolutely nothing…
