New toy alert! It's a Sharp MZ-2500 from 1985, otherwise known as the 'Super MZ', the last of the extensive Z80 based MZ range. Up to 256K RAM and 128K VRAM, it has a 6MHz Z80B and can do 16 colours at 640x400 (if you have all the VRAM). It also looks wonderfully like a top end HiFi separate ... 1/2

I couldn't find an empty takeup reel for the 2 track reel-to-reel player (I'm doing reel to reels now!) so I ordered one, which means I should find one in this office within a few seconds of the box arriving.

It is with a heavy yet hopeful heart that I announce that my beloved Super Mario Bros. prototype cartridge has left and arrived at its new owner's home. We spent one last day together doing all of its favorite things. The proceeds from this private sale will benefit VGHF doing even more cool shit.

My post on LinkedIn:

"Almost every post I see on my feed on this site is about generative AI.

I have never used AI to write code, and I hope I never will.

My entire purpose as a software engineer is to solve problems by writing and debugging code. I'm good at it. If there's a problem I don't know how to solve, I will research it until I understand it. And I will write every line of code myself, knowing how it all works, so that if subsequent bugs or changes to the design arise, I will know exactly where to look to make adjustments.

A few years ago, I realized I needed to emulate a certain function from a web app in a local Python script for parity to fix a very subtle but very critical bug in a game. The web app was written in TypeScript (a language I wasn't familiar with), and the person who wrote the web app was no longer available to contact. So I dove into the TypeScript code, figured out what it was doing, and rewrote it in Python. And sure, rewriting a single function into another language is probably the sort of thing an AI would be good at doing. But that was the easy part. Understanding that this was even a problem that needed to be solved in the first place is something that only a real human being would notice, and it required a ton of audiovisual context that I would have no idea how to even begin to describe to an AI.

You need real people to solve real problems."

LinkedIn is a pretty terrible site but sure I'll bring my slightly hostile anti-AI takes over there why not. The worst that can happen is that I don't get considered for a job I'd hate to do anyway.

This picture of Astronaut Christina Koch after the Artemis landing is frankly incredible and beautiful.

Nobody joins a Cult.They join a group offering answers, belonging,purpose.Usually with a bold Leader. Followers think that the Charismatic Leader is the ONLY one w/ the answer,so they do what is asked.They lose sight of morality, logic, they double down. They drink the Flavor Ade. They don't return.

The last MP3 patent We still use MP3 a lot, we just don't have to think about it much anymore

What happened when the last MP3 patent expired 9 years ago? A dirty trick was what happened, that's what. The inventor tried to declare the format dead so they could sell something else. But you still listen to MP3s, even if you don't think about it much anymore. dfarq.homeip.net/mp3-is-dead-...

this morning, mamdani’s team got in touch with me to float a new tax proposal: if your net worth exceeds $5 million and you dress badly, you’ll be hit with a 10% annual levy for “visual pollution.” i would be in charge of deciding if the outfits are bad.

This is a well-documented pattern in medical research and reflects systemic gender bias in pain assessment and treatment.👇

Added a rare card to my 3dfx collection today. This is an OEM version of the Voodoo 3 3500 running at 183MHz. It lacks the TV tuner and massive dongle of the retail 3500 TV.

Was listed incorrectly on eBay as a 3000 for a meh price. Thankfully I recognized it and jumped! 😁
