How to: Encrypt Your Windows, Mac, or Linux Computer Encrypting your computer's storage drive is a simple, but powerful tool to secure your data. When enabled, "full-disk" encryption (also known as device encryption) encrypts everything on your computer so it cannot be viewed without first entering a password when you log in. Just to instructions for: Windows Mac Linux...

Both Windows and Mac computers include a free way to encrypt your entire storage drive. You should turn it on, if you haven't already. ssd.eff.org/module/how-...

If I still had my Super Nintendo Chalmers I'd want that skin.

I have a Super Famicom and a Super NT, but it's not the same.

Thx. I love the general look of raycasters. Now that I get how they work, I want to put them on everything. I've got a version running in raylib and I wonder how difficult it'll be to get a low rez version running on my Atari.

I want to get this optimized on genesis and hopefully networked first.

Thanks. I wasn't really happy with the way things looked with mirroring. I think this is a good compromise if I can keep this frame rate as I add in more features and optimize.

✈️Burbank’s control tower temporarily closed overnight due to staffing shortages.

As the government shutdown continues, will this continue? Maybe.

In 2023, nearly half of Federal Aviation Administration (FAA)'s 290 facilities were understaffed. Burbank Tower was 100% staffed.

Rewrote my #SGDK / #segagenesis raycaster again. This time to get rid of the Toy Story mirroring. The FPS dropped of course. But I think I'd rather run 10 to 13 FPS without mirroring the screen than run 15 to 20 with mirroring.

There's still some optimizing I can do, so maybe 15~ish is possible.

Pleasant surprise today. I bought this Atari 400 about a decade ago off goodwill. I assumed it was 16k and forgot all about it. Remembered it today and was thinking I’d mod it with more memory. Looks like it’s already been modded.

It didn't really have any better suggestions than what I'm already considering. I hope to have a faster version of Mega Driving coded after I get one a 4-player retrolink game working.

Atari 800/Fujinet and MegaDrive/Retro.LInk Chess server test
YouTube video by Greg Gallardo Atari 800/Fujinet and MegaDrive/Retro.LInk Chess server test

Moar retro networking. #fujinet and #retrolink

When I get back to this I'll probably rewrite the Atari version in C or Assembly. Fastbasic is nice, but I'm interested in trying out other languages with the fujinet.

We promise this pandemic was only virtual.

20 years ago, an unexpected event in the online game "World of Warcraft" caught the attention of players and researchers. A new dungeon introduced a boss whose special attack temporarily drained a player’s health and could spread to others nearby. πŸ§΅β¬‡οΈ (1/3)

Atari 800XL acting as a stockfish UI with #fujinet through a webserver. I'll have to think a bit on how to make the webserver handle two players. I want to update my Sega retro.link version first.

As it turns out, it's trivially easy to make a #fujinet talk to a Python webserver (with python-chess) in front of Stockfish. No need for me to move my valid-move code to a webserver.

I POST moves and GET the current board. I should be able to make both my A8 and SGDK chess boards talk to this.

I plan on doing something more significant than tic-tac-toe or chess with FujiNet soon, but I want to get my raycaster working with several Segas first.

There's a separate project (gitlab.com/doragasu/mw) that uses ESP32s but I don't have one and emulator support is not ready last I checked.

GitHub - b1tsh1ft3r/retro.link: An Ethernet cartridge adapter for retro video game consoles An Ethernet cartridge adapter for retro video game consoles - b1tsh1ft3r/retro.link

The Sega side is a #retro.link device. github.com/b1tsh1ft3r/r... Not my project, but B1tsh1ft3r gave me two devices to work with a while back. It's TCP only, so I'd need my own HTTPS. I don't see myself getting SSL running on a MegaDrive, so I'd have to write proxy server as a go-between.

Right now it's dependent on the Sega to check for wins. I'll update the A8 code over the weekend to make it work without the Sega.

I'm currently trying to convince myself to convert my valid move code from SGDK/C to fastbasic. Or switch to using a dedicated TCP or HTTP server for chess games.
