Now we just have to find some worth copying and repurposing. That might take some time.

Part of me is surprised. The other part of me shrugs and says they bought a Tesla, of course they wouldn't know.

I'm very surprised I've never used "Microslop" on my blog in 27 years. Microsloth, yes.

We used to go to Target multiple times a week. Now it's once a year. We'll go to everything from Dillard's to Dollar Tree before going to Target. And this is coming from a guy who dislikes Walmart and Amazon almost as much. They're once-a-year last resorts too. We shop at Costco and Aldi a lot.

What privacy? Meta's smart glasses are filming unwitting naked people Meta's Ray-Ban smart glasses are a privacy nightmare, with footage of naked people, sensitive information, and violent acts captured and seen by Meta's AI and an army of employees.

Buried lede: Meta sends all your nudes to Kenya where humans annotate it and feed it to AI

I have that same chip in my 386! Wouldn't it be funny if we had the same motherboard too? There were lots of those though, so that seems like a long shot.

Intel 486DX2 CPU It remained the mainstream CPU even after the Pentium hit the market

34 years ago today, a legend was born: Intel's 486DX2 CPU. It was a compromise to help the 486 scale to higher clock speeds, and to say it worked out well is an understatement. #retrocomputing #vintagecomputing dfarq.homeip.net/intel-486dx2...

AMD Am386 released March 2, 1991 Intel tried everything, including trademarks and trying to revoke 286 rights

What happened to GEM? It went open source in 1999 but the code has been dormant since 2008.

For a short time, it looked like the future of graphical user interfaces wouldn't be Windows, but instead, something called GEM, from a name that may sound familiar. #retrocomputing #vintagecomputing dfarq.homeip.net/whatever-hap...

Game designer Sid Meier born Feb. 24, 1954 Meier's run of games starting in 1987 are timeless classics.

This week is Sid Meier's birthday. That makes it a great time to look back on the many games he designed. Civilization probably shaved a good .25 off my college GPA. #retrocomputing #retrogaming dfarq.homeip.net/game-designe...

What happened to Fry's Electronics Fry's had been struggling for years but it was still a bit of a surprise to see it go

Where do I volunteer for jury duty in this trial? I can be COMPLETELY impartial in a trial involving Elon Musk. I'm even willing to spell his name right if that lets me be on this jury.

Turns Out There Was Voter Fraud in Georgiaβ€”by Elon Musk The state board of elections found Musk’s PAC sent prefilled ballot applications.

The story that Elon Musk committed voter fraud has gotten next to no coverage -- one of those things you can't make come up on a Google search.

But I think it's time for Dems to go on offensive abt right wing coddling of this immigrant interfering in our elections.

I was shopping for a computer circa 1994 and asked what brand the video card was, because it seemed like a no-name card. The salesguy said "VESA" and pronounced it "VISA." Yeah, it was a no-name card.

On February 20, 2010 a VIC-20 tweeted 5K of RAM ought to be enough to tweet, right?

I'm more interested in what a VIC-20 has to say here than over at Elno's place, but the VIC's tweet seems lost to history anyway. Retrocomputing is supposed to be a break from the socials, right? #retrocomputing #vintagecomputing dfarq.homeip.net/on-february-...

Office Space released Feb. 19, 1999 20th Century Fox thought it needed more flair. But I think it was perfect.

27 years ago, Mike Judge released his masterpiece. It was a dark comedy about working in the technology world, and it still resonates today. If you've ever had a case of the Mondays, well, say hi to Lumbergh for me. #retrocomputing dfarq.homeip.net/office-space...

Windows 2000 release date It had MMC, Active Directory, and Plug and Play, among other features

26 years ago, Windows did a lot of growing up. Windows 2000 wasn't quite ready for widespread home use, but it brought better ease of use and reliability improvements to Windows NT 4.0. #retrocomputing #vintagecomputing

ISSOURI – The β€œOne Big Beautiful Bill,” the spending package recently signed by U.S. President Donald Trump, is expected to drive up utility bills over the next decade, with Missouri currently projected to see the highest increases in the nation.

According to an analysis from Energy Innovation, Missouri households are projected to face the nation’s steepest increase in annual utility costs, expected to rise by an estimated $640 by 2035.

(2/11) You know dynamic pricingβ€”think Uber rides, flights, or concert tickets that surge based on supply and demand. β€œSurveillance Pricing” takes this to the next level: using your data to set a β€œprice for you” based on your predicted breaking point. This is, increasingly, everywhere.
