ESP32 Buyer’s Guide: Different Chips, Firmware, Sensors
The ESP 32 was the most fun side project for me in 2022. For those who don’t know: the ESP32 is a small, cheap and wifi-enabled microchip. Many smart devices that you buy on Amazon have an ESP32 inside. It’s really amazing what you can do with a board that costs less than a good sandwich.

The benefits of everything being a buffer in Emacs
For today I only have a very short tip – or maybe let’s call it an anecdote. (This is not because I didn’t have time for writing last week. Quite the opposite – I’ve been working very hard on one of the projects I mentioned in my 2023 planning post . I think I’ll be able to share some details next week.)

SirTunnel, a personal ngrok alternative
From time to time I need to expose a development web site or web service to the world. In the past, I’ve used ngrok for that, and of course long ago I built ReverseHTTP which is somewhere in the same ballpark, but I recently got fed up with the state of affairs and decided to see whether there was something simple I…

Mjolnir
As much as I loved the beautiful machine , the passive cooling and form factor of the DB4 chassis had limitations. The best GPU I could fit in (and cool down), a 1050 Ti, barely managed to run Diablo 2 Resurrected. Playing could become unpleasant at 30fps in busy levels!

How to prioritize tasks?
Shipping products is hard. What makes it hard is that typical products involve multiple teams and multiple dependencies. Navigating these challenges is non-trivial. There are technical challenges to overcome, but those are typically not the biggest blockers. (There are enough smart people in the room to take care of…

Although there have been and still are plenty of alternatives to git in the world of SCMs, none other seem quite as prevalent both in open-source and the enterprise.

An unexpected benefit of unit tests
While I won’t go so far as to diagnose myself with ADD without consulting a doctor, those who know me know I can be distracted quite easily. So recently, I decided to do something a little different with a personal project I started a few weeks ago (link to come). I wrote unit tests. That may seem rather uninspired…
