I'm working on a social network based around link sharing! One of the core ideas is that rather than following a whole person, you can follow a subset of their tags so someone can post about obscure cheeses and ambient electronic, but lactose intolerant you can just follow the music. Or you can follow someone's tech posts but not follow news of their dysfunctional city. Honestly a lot of it is resurrecting ideas from…

This kind of reminds me of Google Circles where you would group people into areas of interest. I always thought that idea was really good and should’ve been pursued further.

For me the most important issue that needs to be solved right now is the increasing urban sprawl and the car dependent neighborhoods. It causes social isolation. Maintaining infrastructure like roads and electricity, is causing a strain on the economy for local municipalities. Not to mention the disastrous effect car based transportation has on the environment. I am a fullstack developer living in Norway. Last year I…

Interesting!

As a fullstack developer, how did you even landed on such projects? Are you even using your SW Engineering skills in this? I really want to know more how are you able to lead an urbanism and architecture project with, supposedly, no formal backgrounds. Are you partnered with other people in this endeavour?

I am spending my retirement working part-time on a realistic spacecraft simulator (3D, VR) set in the late 20th century on a fictional moon made of Tungsten ("Tungsten Moon"). For some reason, I decided the spacecraft needs a "real" flight computer with code that can be modified by the player, so I am now deeply immersed in coding a Forth virtual computer ("AMC Forth") to run in-game. It will control the navigation and systems on the spacecraft. If you've gotten this far, and you're intrigued, you can try the free demo on Steam (no Forth machine yet).

Decarbonising buildings and massive warehouses..

It's a very fun mix of hardware (for data collection), and crazy SQL queries to model energy flows between buildings, solar, batteries, etc. Considering just one building is pretty easy:

consumption = imported - exported + generated - stored + dispatched. carbon = carbon intensity * imported cost = tariff * imported

but then you add a site with a couple of buildings, solar on one of them, grid limited exports, etc modelling these flows is challenging. Like consider the case where one building got 10% of it's imported power from another building's excess solar, then calculating carbon becomes more difficult.

and once you've figured all that - then you have to figure out what makes commercial sense to do next.. install a battery, expand solar, move onto a TOU tariff, do nothing - and that's a whole other world of optimisation problems.

I’ve been looking for work!

But to pass the time, I’m also working on a personal journal that keep S-expressions in a database with a well-defined schema set by the other nodes of the database (imagine tiddlywiki transclusions everywhere!)

The idea is to have a bunch of adaptors for Google Takeout, Apple Notes, Obsidian, Apple Health, fitness tracking, org-mode, location history, etc. keep all my data there in well-defined formats. I could then also use the markup language I’m writing to present my journal data in various ways.

My main focus is on efficient data entry/ingestion powered by schema-as-data, which allows for machine and human readability.

I don’t expect it to be useful, but I’m having fun. If I wind up getting anywhere, I might open source it.

I built a CNC router table and am enjoying getting a hang of that. I have always wanted to take my software and systems skillset into the physical world.

I wouldn't mind making boutique sim racing/flight gear, or aftermarket car parts like cyberpunk-esque dash readouts and stuff like that.

That's the more hobbyist stuff, and more broadly I am also learning Japanese, and making games. They sound separate but I am hoping to blend the two skillsets and make games that bridge a gap I see there.

I think that good innovation only happens at the intersections of things we already know. That way you have the depth of understanding required to be useful rather than just new.

Putting the finishing touches on my LLM based town simulator. Once it's finished I'll have it simulate 4 hours in the town every 2 hours in reality. It is designed to solve the problem of "RPG hero just killed a dragon in front of the town and no one says anything about it." All the NPCs realistically react and talk about the Hero's exploits. Visitors to the site can vote on what quest the hero undertakes next. I'm r…

It would be great to give each of the NPC's their own character. For example, some of the NPC's could have a grudge against the hero for reasons of their own. They could be cheering against him for causing such a ruckus in their village, or maybe some "Monday morning quarterback" happening, thinking they could have handled the problem much better than he did. I think an LLM may be pretty good at coming up with some ideas. Or maybe even make it a bit tongue-in-cheek and have some of the NPC's be fans of the hero's enemies.
