I wrote about my early experience with M700S LoongArch based mini PC. Open it up to look inside, and install Linux on it. There's a bunch of pictures too.

The tech elite arenโ€™t just taking your autonomy via Artificial Intelligence; theyโ€™re building underground fortresses to survive the consequences.

This should terrify everyone.

RoboCop โ€“ The Future of Copy Protection Arcades in the late 80โ€™s / early 90โ€™s were a big deal, the cutting edge of gaming. So big in fact that bootleg versions of top of the line games would appear on the black market. A quicโ€ฆ

Afternoon.. seems I found the copy protection in RoboCop arcade. So I made a blog post about it.

The only thing I can infer is that there's an objection to the metal source, but I don't know if the objection is because it's from an aggressor or defender - and what perspective for each, or if it's just due to that fact it's from instruments of war.

Or if it's because it's emulation or cost.

I've never played a GTA game for more than a few minutes and this Christmas I decided to change that with GTA V.

After playing for over three hours I realised the cops don't chase you for running red lights.

The rest of the game should be a little quicker to play now.

I finally got around to picking a game from my backlog and playing it.

#Control (2019), by Remedy on the #PS5.

Firstly I can't beleive it's 6 years old! I've tried to play it twice before and it didn't grab me, but this time I really enjoyed it. So much so I got the Platinum trophy.

Who is this Gerry Mander everyone is talking about!?!?

He's crazy popular. The Republicans want him in Texas and the Democrats want him in California. I bet he feels like a kid with divorced parents at thanks giving..

Poor bloke.

I can think of two:

"Morality Needs No Priest"

Or

"Jesus was a socialist"

AI then told me my theory answers most of the current open questions in physics and proved it to me using math.

The T-Symmetric Cosmological Model Accelerated Expansion as a Perceptual Effect of Time Reversal.pdf

I made a totally crazy theory of reality using AI.

This paper explores the T-Symmetric Cosmological Model - observed acceleration is a perceptual effect arising from observers existing within a physically contracting branch of a time-symmetric universe.

Further confession: one of my most favourite Final Fantasy memories is playing Final Fantasy Legend II on the original GameBoy, and that's not even a real Final Fantasy game, it's a SaGa game.

Confession time: I've never played Final Fantasy VII past the village, although I often claim it's a masterpiece.

In my defence, I have read a lot about it, and I have tried to play it a number of times on the PS, PSP, PC and on emulation.

Oh please do! There was a guy on Twitter that posted a photo of a stack of them...

In situations like this, I've head people buy new machines, then return their broken ones saying it didn't work when arrived.

Of course, I'd never do that. It would be immoral to deprive a billion-dollar corporation that pays their staff less than a living wage of a sale ๐Ÿ˜œ

Oh, you should do! It's a really interesting side hobby for techs. With your electronic skills you'd be brilliant at the hardware side of things.
