I might have put this before but it is always relaxing read: Commodore 64 catalog by Finnish Commodore importer PCI-Data from 1985. It has all the best products, including C64 Jump Suit:

Ive never had a sleeping rhythm: i just pass out and wake up randomly. Lately Ive found great help from Melatonin combined with audio book about geopolitics, history and similar ”in-depth” topic. It seems to really do the trick for me. Nice to have a rhythm

TIL about Irdabama, a powerful Ancient Persian (Iranian) businesswoman who, ~2500 years ago, controlled vast estates, traded across the Achaemenid Empire, managing hundreds of workers whilst travelling around Iran and Mesopotamia with her own entourage.

As I like be open about my downs too, and not just ups, I already feel that #EdTech is much more me than #blockchain tech :-D I feel I made the right choice this time.

And generally speaking, maybe it is a good profile for someone working on technology for schools, to be one who does not pretend to be perfect, and actually makes mistakes sometimes.

If you ever find yourself saying “It’s just business” to justify an action, you should pause and recognize that the presence of that phrase is a sign capitalism has begun corroding your brain's moral center, and is alienating you from your own beautiful humanity!

This is what you see when you boot the game:

Adding a WiringPi module to TIC-80's Python interpreter https://rvr.typepad.com/wind/2025/03/adding-wiringpi-module-to-tic-80-python-interpreter.html

This is a project that I worked on last weekend. TIC-80 is one of the most popular open source "fantasy consoles", imaginary retro-console emulators with IDE for code, sprites, maps and music. I show how to extend TIC-80's Python interpreter, pocketpy, to add GPIO access for the Raspberry Pi.

Edit: Just uploaded the code to github.

One area where I think AI is quite nice: I like to tell roughly how a sequence should look like and ask AI to do me a snippet of Mermaid.

It's far from truth but then I can continue editing the snippet manually. My biggest difficulty with Mermaid is that I use it so rarely that I forget the syntax so this will help me to recall all of that. That's actually gist of this whole exercise.

It does not even require powerful AI: I use a local Ollama running llama 3.2 on my RTX 4090. The sequence does not need to be correct as long as it has about the right lanes and some stuff going back and forth.

This makes me wonder tho what is the value of paying Mermaid Charts, which does this on a paid subscription (that's where I got the inspiration in the first place).

This makes me wonder also all of the paid stuff. If you are smart software engineer in the first place you can get 90% of the "efficiency benefit" with a local 2k-4k GPU, which mostly recalling syntax of e.g., Mermaid.

Interesting, I thought that I'd save time on looking Intel SDM just to check up the size of PCMD, one of the data structures in Intel SGX.

I tried Google Gemini and two different AI flavors it has and got three wrong answers.

So eventually I went to Intel SDM and got the answer that I wanted :-)

If this is AGI, it will suck...
