OSS is on fire; no way can the model keep up with all the updates in the libraries.

Look how many HTTP calls my agent is not making thanks to #POSHTUI

My business adviser said that I do too much. So I'm cutting down on everything. There are 4 focus areas: - be with family more, help wife with her business, son with his hobbies and school. - turn Posh TUI into a product - work on trainings with @lucianghinda.com - kickboxing

A lot of things had to go unfortunately. Even I enjoyed these. Dutch classes, gym membership, wakeboard, tourist plans and etc.

My wife finally understands what her husband does in front of the computer. My mediocre SEO and social marketing skills have been enough to bring new clients to her beauty salon.

My son got lucky to be born with two passports. But there is also a way to get a 3rd, Dutch one. It takes 980EUR and a year of waiting... Should I?

Learned a bunch of fantastic new phrases lately: 1. Token-bound — when one’s performance is limited by a lack of AI tokens. 2. Trad programmer (or coder) — someone who writes code by hand. 3. Token laundering — when you let a colleague Slack you a prompt to run with your own AI allowance.

My wild guess is that potential users of Posh TUI are probably on Omarchy or using VS Code. So packaging for AUR + polishing the VS Code plugin will be my next mission.

Running a startup requires way more thoughtful writing that I'm comfortable with... Can I respond with meme's instead?

It's interesting to see a guy, that invented most enjoyable front end language, for years privately working on a enjoyable language for back-end. And ta-da... it's a compiler for efficient database queries.

Pebble Time 2 has literally replaced 3 watches I had previously.

Posh TUI feels feature complete at this point. Now i'm going through a round of private feedback with friends. But everyone is welcome to give it a spin. Hope to get V1 beta out of the door this month

Replaced wakeboarding with lifting weights. Wakeboarding is fun and everything, but really difficult to do competitively for me (too old, too fat, too weak). Dutch Kickboxing + weight lifting = a perfect combo
