I made a small LED panel
I bought a really small 8x8 LED panel a while ago because I have a problem. I just can’t resist a nice WS2812 LED panel, much like I can’t resist an e-ink display. These days I manage to stay sober, but once in a while I’ll see a nice cheap LED panel and fall off the wagon. It has now been thirteen minutes that I have…

Benefits of choosing email over messaging
My colleagues and friends know that I prefer to communicate with them via email rather than chat messaging. There are many benefits in such a choice. You may want to consider them and adopt the same stance.

Be Worried
Author's note: I wrote this in March 2023, but just published in October 2025. I held back from publishing this originally for fear that I was being sensationalist. But with the launch of Sora 2, I couldn't not share these thoughts. I only regret I didn't publish it 2 years ago.

In Praise of RSS and Controlled Feeds of Information
The way we consume content on the internet is increasingly driven by walled-garden platforms and black-box feed algorithms. This shift is making our media diets miserable. Ironically, a solution to the problem predates algorithmic feeds, social media and other forms of informational junk food. It is called RSS (Really…

You Want Technology with Warts
I normally skip presentations because I prefer reading, but Building the Hundred-Year Web Service (YouTube) was worth the time. 1 1 Note that despite “htmx” featuring in the title, very little of the presentation is actually about htmx. It is about choosing and using technology in such a way that it won’t require…

Babel is why I keep blogging with Emacs
Every time I look at someone’s simple static site generation setup for their blog, I feel a pang of envy. I’m sure I could make a decent blogging engine in 2,000 lines of code, and it would be something I’d understand, be proud over, able to extend, and willing to share with others.

Indefinite Backpack Travel
In 2015 I got rid of everything I owned that didn’t fit in a laptop backpack, and I’ve been living at this level of minimalism since. The idea is to only own what I need, which allows me to focus more, spend less, travel spontaneously and simplify my life.
