Not a big fan of the "we can't tell you the details of what went wrong, but here's a relaxing animation of a farm, trees and birds flying" strategy.

As the share of #postquantum encrypted traffic approaches 50% globally, Radar now checks your browser for PQ support.

Visiting radar.cloudflare.com/adoption-and... will show you if your browser supports PQ encryption, and if it does, which key agreement it is using.

This video phone works and is from 1970! Needless to say it was a huge flop but you could make video calls.

Yesterday, I was lucky to be able to spend a couple hours at the Connections Museum with Sarah Autumn.

I had a stupid grin on my face the entire time!

Even after a couple hours, we just barely scratched the surface of what's there. It's unbelievably awesome.

Why does an Amiga's floppy drive keep clicking? I seem to remember that an A500 (probably A600 too) would keep emitting a click from the floppy drive. I think this was only with no disk in the drive, but I'm not sure. What was that?

You can use the floppy drive to play songs, but this clicking sound of the Amiga that Adrian mentioned is another thing retrocomputing.stackexchange.com/questions/17...

One of the things I miss from working in a big telco is access to a retro computing museum, where you could pick stuff up for free that they would otherwise have to dispose of, at cost

Ceramic white 6502 CPU from 1975

Ceramic white 6502 CPU from 1975

Happy birthday to the MOS 6502! It was 50 years ago today that people were able to buy their first samples of the chip from a jar in a hotel room at WESCON.

Here's my oldest 6502 from the 52nd week of 1975. Still works perfectly!

The retro computing scene is on fire, launching modern replicas of once-upon-a-time relics. A new Amiga now.

Yup. VGA from the Acorn to the GBS who handles and scales resolutions at 15Khz used in games, and then VGA out to the monitor.
