I started playing chess for real about a decade ago. I used it to overcome my annoyance when I lost in life. Losses would have an impact, so I decided to play chess until loss didn’t have that impact. It took 3 years and some 30K blitz games (1 minute games, 1+0) for that irritation of losing to subside. I deliberately didn’t try to get better, and so I lost around 50% of the games... Read more!

I’m mostly a software guy. Except for chemistry and blowing stuff up, I’ve not tinkered much with hardware. But I’ve been fascinated by it, and especially with electronics. So far it’s been contained to electronics modding on HP calculators. I decided I need a tool that can teach me electronics properly from the ground up. circuit is an electronics bench in the terminal. Put batteries, resistors, capacitors, LEDs, switches and transistors on a grid. Wire... Read more!

I really like our moon. I like that it’s big and the exact right size and distance to make for great solar eclipses. If I ever went to Mars, I would miss our moon moon shows the Moon as it looks tonight. Craters and seas, the lit part bright, the night side dark gray. Along the bottom sit the phases of the three days before and the days ahead, to the edge of the window.... Read more!

Like I said in the CHasm README: don’t use my tools. Clone them, fire up Claude Code and make them yours. That’s still my message. But you should be able to try them out. With very little effort. It wasn’t easy before. Ten repos, ten builds, five config files to write, a wallpaper to bake, a session to wire up. Now it’s three commands: git clone https://github.com/isene/chasm cd chasm ./chasm-install What you get The whole... Read more!

A month ago I drew a map of everything I have built. It is already out of date. Seven apps have landed since. Six on the laptop, one on the phone. I’m not standing still. Speed is crazy these days. fleet I run several Claude Code sessions at once. Which one has finished and waits for me? Which workspace is it on? How much context has it burned? fleet is my TUI app for that.... Read more!

Photo by my good friend Trond Alexander Tune (Zander). Our King died yesterday. He represented Norway in a transition from the old and formal to the modern age. His warmth and inclusive mindset helped shape Norway to what it is today. He was funny and serious, down-to-earth and yet royal. He did most everything right. He even died at the right time. Missteps by other members of the royal family had been weighing down the... Read more!

I started programming when I was 13. Basic, then lots of work in FOCAL on the HP-41 calculator, then OPL, Pascal, MCODE, Assembly, Visual Basic, Ruby, Fortran, Python, Forth and more obscure languages. Lately with the use of Claude Code it’s been a massive amount of Rust and Assembly. I’m starting to lose track of it all, and being a somewhat visual guy, I decided to make a map of most of my programming projects.... Read more!

Been doing digital art since the mid-90s. Since I am living in the terminal, I decided to improve the ascii part of image displays. Usually I get images to show inline in the terminal via the kitty protocol, but now and then I am on a server via ssh and still want to see some images - or at least what they look like. Hence an update to my graphics engine. Kitty on the left... Read more!

I’ve always been drawn to the really big and the really small. From astrophysics and cosmology to particle physics and quantum mechanics. I am fascinated about what happens at the edges of reality. I started wondering about the elements beyond 120 when I was a little boy and the structure of those nuclei and their break-downs. I read frontier articles on astronomy and wondered what a 6-star system would be like. The books and the... Read more!

I love our sky. I love the terminal. Now they fuse. My astro app has always shown a star chart for the hour I pick. It fetched it from a website, as a picture, one per hour, converted through ImageMagick and cached on disk. Now it draws its own… in braille. What it draws 9,096 stars from the Yale Bright Star Catalogue, and the constellation figures. The sun, moon and planets where they actually are... Read more!

Two days ago I posted five new tools. Yesterday two more. That puts 27 apps in the Fe₂O₃ suite, and I am starting to lose sight of all the wonderful apps. So the suite got a front door, simply called fe2o3. The grid Every app as a card: its logo, what it is, one line on why. Arrow keys move. Enter runs it in the same terminal, and when you quit you are back on... Read more!

Yesterday I posted five new tools. Today there are two more, and they are both science. My mother got me going when I was 8. She pointed to the sky just above the apartment building where we lived (Tveita, Oslo) and said, “Do you see those three stars up there? That’s the belt of Orion”. I was hooked. Four years later I was hanging out at Oslo University bugging professors in astrophysics with questions about... Read more!
