https://www.lunesu.com/I'm a wanderer with an interest in programming, hardware, hacking, languages, food, coffee, science. This blog mostly serves as my private knowledgebase, but I figured it might be useful to others. 2026-09-14T20:59:43+00:00 Lionello Lunesu https://www.lunesu.com/ Jekyll © 2026 Lionello Lunesu /assets/img/favicons/favicon.ico /assets/img/favicons/favicon-96x96.png 2026-07-09T16:00:00+00:00 2026-07-09T16:00:00+00:00 https://www.lunesu.com/2026/07/09/More-AI-Not-Less.html Lionello Lunesu

So I’m going through a bit of crisis, and from talking with other folks, I’m not alone. I don’t think it’s exactly the crisis “the media” is popularizing, “AI is replacing software developers”, although it’s related. It’s rather that using AI tools in some of the daily workflows (some of which are indeed parts I’ve spent tons of time building skills in) means the other, non-automated, parts ar...

Some of the best memories I have are from my time at XinCheJian, China’s first hackerspace. In particular, this bottomless “idea box” 想法箱, strategically mounted on top of the trash can. Every person that came into the hackerspace and offered ideas without intention to realize them (“You know what you should make?!”) was encouraged to write their idea up and put it into the Idea Box. This mor...

You can find the code for this post here and install the CLI with winget install defang or eval "$(curl -fsSL s.defang.io/install)". Christmas is nearing, and this year I’m once again spending time in the Vancouver Hack Space to work on a silly Christmas project to turn a human-sized1 acrylic sphere into a snow globe. I haven’t finished it in the last few years, and I likely won’t finish it ...

When I went to Europe this summer, I was eager to try my Commodore 64, because I had just bought the Ultimate II+. This cardridge emulates the 1541 disk drive, and has a lot of other features, like Wi-Fi, custom kernals, and an (optional) tape emulator. When I got to my parent’s place, I tried to turn on the Commodore 64, but it wouldn’t turn on. I thought it was the power supply, because the ...

This is a small shell script that I wrote to help with encoding/decoding Base64-URL encoded data. It basically invokes the platform’s base64 and sed to turn regular Base64 into Base64-URL. By the way, this is using the following markup to embed a Gist in Github Pages. You’ll need to install the jekyll-gist gem to see this locally: {% gist 6bb597fc600932c6c737aab3b402147c %} 404: Not Found
