DIY PTP Grandmaster Clock with a Raspberry Pi
tl;dr: I set up an open source Time Pi project to build a stratum 1 PTP and NTP timeserver using a Raspberry Pi. Time is important to modern society, and most of us have a clock on our wrist that's more accurate than at any time in human history. But highly precise time is important in many industries, especially…

How to write blog posts that developers read
Software bloggers can make the same mistakes for years that prevent readers from discovering their writing. I know because I'm one of them. Over time, I've learned techniques that help some blog posts succeed and the pitfalls that cause others to languish in obscurity.

Using uv and PEP 723 for Self-Contained Python Scripts
We all love Python’s comprehensive standard library, but let’s face it – PyPI’s wealth of packages often becomes essential. Sharing single-file, self-contained Python scripts that rely on these external tools can be a headache. Historically, we’ve relied on requirements.txt or full-fledged package managers such as…

Golang on the Playstation 2
The PS2 is more than capable of doing some wild things, including running Linux. I always wondered if we could just write baremetal Go code on it, so I decided to give it a try.

Take this on-call rotation and shove it
At some companies, it is expected that certain engineers will serve as part of a formal on-call rotation. On paper, this seems like a reasonable way to ensure the reliability of the product. In practice, it is a miserable burden and you probably won't even get paid for it.

Some time ago, I saw this video by DIY Perks where they make artificial sunlight at home with a 500W LED and a gigantic (1.2m) parabolic reflector. I've been...

Modern C
This new edition has been the occasion to overhaul the presentation in many places, but its main purpose is the update to the new C standard, C23 . The goal was to publish this new edition of Modern C at the same time as the new C standard goes through the procedure of ISO publication. The closest approximation of the…

It's five grand a day to miss our S3 exit
We're spending just shy of $1.5 million/year on AWS S3 at the moment to host files for Basecamp, HEY, and everything else. The only way we were able to get the pricing that low was by signing a four-year contract. That contract expires this summer, June 30, so that's our departure date for the final leg of our cloud…

The Website Hacker News Is Afraid to Discuss
What bothers me isn’t so much that Daring Fireball is shitlisted at Hacker News. What bothers me is that it’s unexplained.

Better Shell History Search
I spend an awful lot of my day in Unix terminals running shell commands. For some reason, the variance in efficiency between different people when using the shell is huge: I know people who can run rings around me, and I’ve come across more than one paid professional who doesn’t use the “up” key to retrieve the…

Sell yourself, sell your work
I've dealt with any number of technically brilliant people who produce outstanding work. The majority of them never bothered to write down their work and communicate it to others - report writing is too boring, uninteresting, and hard. And irrelevant. Or so they thought.
