Create the problem and then sell the solution? Apparently people need this because they're being overwhelmed by the number of pull requests made by Claude Code. https://techcrunch.com/2026/03/09/anthropic-launches-code-review-tool-to-check-flood-of-ai-generated-code/

A few years ago I designed a way to detect bit-flips in Firefox crash reports and last year we deployed an actual memory tester that runs on user machines after the browser crashes. Today I was looking at the data that comes out of these tests and now I'm 100% positive that the heuristic is […]

I've seen a lot of people talking about the practice of code review in a way that I consider unrealistic lately. So here are my thoughts on what code review is—and isn't—for: https://blog.glyph.im/2026/03/what-is-code-review-for.html

I decided to put the working magic incantation on my blog so hopefully someone can find the answer quicker than I did (or AI may be able to provide correct answers 😂 ):

Goodness. Just spent HOURS trying to figure out a udev rule to make a Brother PT-P700 label printer accessible from a user-level #python script.
It involved unbinding the kernel driver and selecting a USB configuration.
This shouldn't be something so difficult it should take HOURS. I had also […]

A subscriber kindly suggested that this update about voltage considerations for the ManT1S should have included something about safety when using higher voltages, and I agree!
I now added a short section on safety at the end of the above update! 👆

The campaign may be over but you can still pre-order a ManT1S! And I finally found time 😅 to start to document how to power a ManT1S and the T1S mixing segment in Power considerations Part One: Voltage

Oof, the second #RaspberryPi price-hike in two months is here. Three months ago, the Raspberry Pi 5 16GB had a $120 RRP; it's now $205.

Thanks, #AI(!)

Someone I know has an immediate urgent need for someone who can use AutoCAD Electrical and can help layout some control panels.

My review of the Nüborn Baby at 3 months My Nüborn Baby arrived in October, and now that I've had a few months to get used to it, I thought I'd write up a review, in case you were thinking of getting one for yourself.

As far as product reviews go, this is pretty accurate.

Iterative Hardware Improvements The Pareto principle, also known as the 80/20 rule, states that for many outcomes, roughly 80% of consequences come from 20% of causes. The pursuit of getting the last 20% right is the reason that both ManT1S and ManT1S-Bridge are already on revision five before they are even released!

In the latest #campaign update, I show the journey from first #prototypes to where we are today. Just a few hours left on the campaign if you want to get your feet wet with multi-drop 10BASE-T1S #networking! 🤪

Network Performance Expectations One of the comments that tend to pop up about ManT1S is: "Why resurrect 10 Mbit/s networking, when we now have multi-gigabit alternatives?" Some people like to oversimplify complex engineering decisions to "just go with the highest number" or "I'll settle for nothing but the best", where "the best" invariably is defined as some high specification number in one single dimension. While that's the kind of story marketing departments may like to push, engineering requires a different approach...

Check out this ManT1S #campaign update on what kind of #performance you can expect from T1S networking: 👇

Development Model With & Without the ManT1S-Bridge Thank you all for your continued support! The ManT1S campaign is now over 300% funded! :) In this update I wanted to show some of the features of the preinstalled MicroPython firmware to make your life easier, and the differences in use depending on whether you are using a ManT1S-Bridge or not.

What are the differences in using a ManT1S when connected to your network with a ManT1S-Bridge versus stand-alone? 👇

Over 200% Funded! And Off-Beat Use Cases In this update I want to explore a few off-beat use cases for the ManT1S and ManT1S-Bridge. I would imagine that most use cases would involve a few ManT1S boards and a ManT1S-Bridge forming a distributed system, but this surely doesn't need to be the case. Both the ManT1S and ManT1S-Bridge have some great features that make them useful in their own right!

How about some off-beat use cases for the ManT1S and ManT1S-Bridge to start the week? 😁

What Kind of Wire Should I Use With the ManT1S? One thing that may be confusing about T1S is that you can't really go to the store and buy a "T1S cable". For standard Ethernet, on the other hand, it's easy to find pre-made Cat5e or Cat6 cables, or to crimp a couple of RJ45's on a length of cable yourself. Luckily, it turns out that the solution is quite simple, and T1S is very forgiving when it comes to the wiring it can work with!

Do you think finding suitable #wiring for the ManT1S'es 10BASE-T1S #network is difficult? Let me convince you otherwise!

Termination, and Introducing the ManT1S-Gadget! In this update, I cover endpoint termination in T1S mixing segments and announce the ManT1S-Gadget, which will ship as a freebie along with each ManT1S Starter Kit.

What is termination? How do you do it on the ManT1S? And introducing the ManT1S-Gadget for added #flexibility in termination and #power injection!
