Three shells. Three languages. One obsession with going deeper. And faster. I started with hand-crafting rsh. Written in Ruby over a few years. Now 4,048 lines, full-featured, comfortable, slow. 300 millisecond startup. Fine for a scripting language, frustrating when I open lots of terminals in quick succession. Then I decided to rush to the next level. Rewriting rsh in Rust. Rush has 4,280 lines, same feature set, 26 millisecond startup. Part of the Fe2O3 suite... Read more!

Nine months ago I stopped reading code. I haven’t read a single line of code since July 2025 - including all my main projects like my shell, file manager, my TUI library and all the other terminal tools I use every day. And in those nine months, I have produced far more software than in any comparable period of my 40-year programming career. The Numbers Since July 1, 2025, working with Claude Code: 1,224 commits...

“Dad, I sent you a message.” “Where? Discord? Messenger? Insta? WhatsApp? Email? Telepathy? Where??” Back in 2007 I had an idea. Collect all messages from all sources into one communication hub. Email, chat, RSS, forums, news, everything. Then create special “views” into all of it, like a “family view” or a “project X view.” When you answer, it replies on the incoming channel. Simple concept. I never built it. Too complex, too much effort. Until... Read more!

I’ve been thinking a lot lately about the use of AI in programming. And I’ve had an epiphany that I believe explains a lot. When I do low-level programming on my HP-41 calculator, the fun is in the coding itself. Not the result. It’s like my collecting of old HP calculators - the joy was never in having a collection. It was in the collecting. If somebody would simply offer me a complete collection for... Read more!

It’s getting cold in Oslo. Had a dinner with the boss two days ago, should have been dressed better for the biting cold. Instead I got a cold. With fever today and a stand-up meeting from bed, I wasn’t much for work. So I decided to build a bootable 64-bit operating system from absolute scratch in a single session. A real x86_64 OS with a working Forth interpreter using Claude Code. My Assembly skills are... Read more!

This is a teaser for my upcoming book, “Freedom Proof” that in turn is based on my TEG framework - the mathematical framwork leading to the necessity of free will. This deep disco version is an alternative take on the track “Free Will” featured on my recent album “The Lighthouse”, available on Spotify and other music platforms. Music and video crafted through AI experimentation, blending genre exploration with visual storytelling. The Original Track Here’s the... Read more!

When creativity hits, it hits hard. The past few months have been an absolute explosion of output across every domain I touch - from synth-driven musical journeys to revolutionary software updates, from academic philosophy to a forthcoming book that challenges our fundamental understanding of freedom itself. Musical Journeys into the Absurd and Beyond Two new albums have just dropped across all major music platforms - Spotify, Apple Music, YouTube Music, and the rest of the... Read more!

After 14 years of HyperList evolution and thousands of users leveraging the VIM plugin, it’s time for HyperList to break free from VIM and become a standalone terminal application. Enter HyperList Ruby TUI - a full-featured terminal interface for creating and managing HyperLists that runs anywhere Ruby runs. What the hell is HyperList? HyperList is my brainchild for describing literally anything - states, processes, plans, thoughts, systems, you name it. It’s a structured, hierarchical markup... Read more!

I’ve been going all in with AI. Programming, artwork, music, philosophical research. All in. Let me share the ride. Programming first. Since May 1st, my babies have gotten massive upgrades. RTFM hit v6.0 with remote browsing, SSH integration, enhanced tab management. The file manager can now browse remote systems. And it’s completely rewritten with rcurses My Ruby shell (v2.9) got AI integration - just type @ or @@ to chat with AI right from the... Read more!

Here is the latest from my deep dive into AI. Music created after a multitude of experimentations with genres and prompts. Images crafted with prompting to fit the message I was looking for. The whole was assembled with a Ruby script crafted together with ChatGPT using ffmpeg to do the splicing. Link to this post: https://isene.org/2025/05/Longing.html Read more!

In the past three months I have been programming a lot with AI. A lot. Among the results are the releases of rcurses and RTFM. Let me share a few conclusions. The positives: When I program with the help of AI my efficiency is 3X-4X While I have programmed in Ruby since 2003, the past three months has made me an 80% better Ruby programmer (check my code for evidence) The coding is much faster,...

Five years and 80K downloads after its inception, RTFM, hits version 5. This is a major rewrite of the whole code - with lots of improvements. RTFM contains everything you would want in a terminal file manager. Among the new version 5 features are an optional trash bin, advanced OpenAI integrations, plugin architectures for keybindings, user defined features and file viewers. You also get better feedback, better visuals, more error capture. Plenty. RTFM used to... Read more!
