Retro programmer. That sums me up fairly succinctly.. whether I want it to or not.
Wrote my first #gamedev #devlog. Using vanilla js and #webassembly through #rust with zero crates, no dependencies, no bindgens. Just bytes in virtual stack+heap. Really reminds me of writing directly to video memory of 8-bit platforms. Tons of fun.

In less than two months we're making ourselves intentionally #homeless by embracing a #nomad lifestyle. We've been planning it for 15 years and spent the last two years executing the move.
Long form guide with tips etc is upcoming but this is what we kept.

Entire family together to this day. Amos was quite revolutionary but it had the dubious honor of being the only way to use basic on the #amiga without tearing your hair out.
That said most of us stuck to c and assembly despite the 7mhz cpu allowing abstraction layers to be a thing. #retrocomputing

Will rework my streams like this; instead of coding it all live I'll prep the code in stages, then show it off live. That ought to be more helpful for learning.
First two projects will likely be making a memory analyzer / editor and a #webassembly game without supporting libraries.

It's my birthday so I'm feeling a bit sentimental. This was the demo tape that my grandfather used to introduce me to computers on his ABC80.
A swedish made micro computer by Luxor AB featuring a Z80 cpu. It launched in 1978 and consistently sold until the mid 80s. #retrocomputing #z80

The Barcode Battler. Used to love this #retro #toy. It oscillated between easily gamed and impossible to figure out (or at least that's how I remember it).
Wonder what happened to mine. Seems like it's always the things you miss that you've lost.. which is logical now that I think about it..

One of us is suspicious of what the other said. Can you tell which is which?

I took some quick excursions into zsh but in general I've used sh and then bash for decades now. nushell is the first shell that made me switch full time. Sure, I get it, "bash works" and change is awkward. But everything about nushell scripting is just magical.

I'm certain most programmers aged 40 and up will recognize "Step by step programming commodore 64" by Phil Cornes. It was a seminal book for many of us.
And then there's the section that inevitably made us all assembly programmers, or at least made us take our first baby steps down that route.

Summer. Finally. First of may was beautiful, then the rest of may was an absolute dumpster fire. Then 31st rolled around and we're back to blue sky (appropriate) and a nice summer breeze.

Never have any idea what to type in "first post". So I'll just include a project photo of using the polaroid sticker printer to make nfc cards that will function as "floppies".
Why? God knows, but it's fun and full of tactile goodness. Also a perfect excuse to dig into the WebNFC API.
