SwiftOnSecurityHistory in pics: Testing prototype Roomba's in 1982. It would take two decades until they could be made small enough to clean under a couch.
Phil Randal@SwiftOnSecurity are you saying that Crays sucked?
Skattrd@PhilRandal @SwiftOnSecurity Crays sucked, and ETAs were so cold they blew liquid nitrogen.
@PhilRandal @SwiftOnSecurity Full disclosure: I worked for ETA Systems for several years until their closure by parent company Control Data Corp (CDC).
Harshad Sharma@SwiftOnSecurity cray-cray!
Glyph@SwiftOnSecurity looks like they were testing it to validate its interaction with washing machines in this picture for some reason?
Final Round Player 😷🇪🇺🍸@glyph @SwiftOnSecurity TFW when you wake from a mid-80s tech nightmare. You went to change the disk pack in the top loading hard drive for the S370 IBM. And it was full of water. The overnight banking reconciliation run would have to wait.

From the back of my mind. Deep in my dreams.
@squareflair @glyph @SwiftOnSecurity That was the dream world nightmare. The Real World nightmare IRL was the operator who couldn't work out why a disk pack wouldn't mount. So he took it out and tried it in the next drive. And then the next one. And now he had one pack trashed with a head crash and three drives with trashed disk heads.
ISTR they were 5Mb drives, but might have been 10Mb.
The year after that I had more disk space in my IBM PC XT than the mainframe had in one of those drives.

Mark@squareflair @jbond @glyph @SwiftOnSecurity A number of years ago I happened to be moving a data center my company acquired. I was amazed to find water lines coming up through the raised flooring. Turns out there was a line of IBM mainframes that were water cooled. As in literal water pipes going directly into the box. I don’t know if that might be the case here, but it’s one possibility.
gnarlygeek@MarkAB @squareflair @jbond @glyph @SwiftOnSecurity Some Cray and Control Data mainframes of the era also had water cooling. It was a little unnerving as a programmer to get a tour in the datacenter and see the interior of a CDC 6600 with the water circulating and multiple oscilloscopes connected while the system was running. We're now coming full circle in cooling large systems. FYI, tape and disk drives, and PDU's usually took up more spaces than the processors.
@gnarlygeek @squareflair @jbond @glyph @SwiftOnSecurity I worked with DEC VAX and Burroughs/Unisys, all air cooled as far as I know. And that was back in the 80’s and early 90’s. I was the CFO of a small DP company and wore a lot of hats since I did the buying/selling/leasing of the equipment and facilities. We grew a lot and by the time server farms became a thing they wouldn’t let me play with their toys any more.
Jeff Morris ZA@MarkAB @gnarlygeek @squareflair @jbond @glyph @SwiftOnSecurity I wrote software for B6700, B6900 and ClearPath monsters.
@jeffZA @gnarlygeek @squareflair @jbond @glyph @SwiftOnSecurity I think the last Unisys system I had any involvement with was a ClearPath install about 20 years ago. Once the company started building mega data centers and consolidating I went back to being a pure finance guy. You don’t get much of a feel for the hardware when all you see is the Fixed Asset Request.
Aphrodite (recharging)before they had the internet to work with they had to roll their own protocols for what we now know as “internet of things”
at least these seem to recognize the S in IoT stands for security
Emily S@SwiftOnSecurity it's easy to clean under the couch when you are the couch

^^^ This person GETS IT
barry99705@Emily_S @SwiftOnSecurity found the cat owner.
Richard "RichiH" Hartmann@SwiftOnSecurity you can clean under the couch when you are the couch.
That Anonymous CowardBut this model was perfect for all of those lifted couches in the south.
accela@SwiftOnSecurity So much more comfortable experience for the cat.

I didn't realize they were first used in laundromats.

@SwiftOnSecurity Those blue washing machines though 🤩 .
kira :3@SwiftOnSecurity you have to appreciate how they tested it in a laundromat, a real "apple was started in a garage" story
Dave Anderson@SwiftOnSecurity picture taken at a test course in one of the first Best Buy locations, in the washing machine department.
Synthomat@SwiftOnSecurity what’s up with all the washing machines and refrigerators in the background?
El Diablo Roboc 😈🤖@synth @SwiftOnSecurity They had to make money somehow
Flatbush Gardener 🌈@synth @SwiftOnSecurity Storage for cleaning pads.

@synth @SwiftOnSecurity You've found where the supply chain conspirators are warehousing large appliances!
Rich Lafferty 🐀@synth @SwiftOnSecurity must be Rush fans
run_atalanta@synth @SwiftOnSecurity Isn't that just an olde photo of Ye Olde Best Byee?
Richard@synth @SwiftOnSecurity It's clearly a big box appliance store. See the guy in the blue shirt?
llewelly@synth @SwiftOnSecurity the laundromats of the 1980s were so filthy only a genius like Seymour Cray could solve the problem.
Noxy 🐾🏳️🌈@synth @SwiftOnSecurity gotta test the robovac in appliance stores to generate hype
Orion Edwards@SwiftOnSecurity I must admit, the blue trim on that row of washing machines in the background is very nice
random thoughts@SwiftOnSecurity
Also consider the blue-white washing machines on the right - these were required because the early Roomba's would leak oil consistently and required frequent washing of the clothes.

Guilherme Brandão@SwiftOnSecurity yes, but on the plus side it took a long time to fill the huge vacuum containers, so it had less maintenance
quello che perde i pezzi@SwiftOnSecurity drawback: you can't seat on it anymore unless you're a cat
90s Script Kiddie@SwiftOnSecurity Posit. People think a bank might be financially shakey...
MikeKSurely the Cray 1 was the most stylish computer in history.
I visited one in 1978(?)
JD Long ✅@SwiftOnSecurity it would be kind of fun to compare the compute capacity of a Cray 1 to a Roomba. Casual inspection makes me think they might be quite similar.

@SwiftOnSecurity @Cmastication Your typical iPhone is much more powerful these days.
Heiko Rupp@SwiftOnSecurity LOL!!!! Made my day
lj·rk@SwiftOnSecurity The Zuse Institute Berlin #ZIB is so big that they still got one of these for cleaning the lobby!
JRT 
@ljrk @SwiftOnSecurity the benefit of the old models is that people can sit on it. The newer models are just for cats. What a downgrade!
@jrt @SwiftOnSecurity No problem for me ^-^'

ChasIn the early 80's a friends boyfriend worked in the server room when the small hard drives were the size of a washing machine
If we wanted extra time for a birthday drink at the pub or a decent lunchtime at a local restaurant, he'd give one or two a subtle kick and then we'd get word from management that we may as well stop what we were doing because the mainframe was down for a couple of hours
Was hard duty working close to IT professionals back in the day
@mvdn777 @SwiftOnSecurity Who remembers word processors before Autosave came along? PCs or mainframes were likely to crash at any moment (that subtle kick) and you could only recover back to your last Save.
It’s not that much different even now to be fair
@mvdn777 set autosave=10 minutes and forget it.
Michael Hartle@SwiftOnSecurity Unknown to many, their initial team of designers left early and founded of a company of their own, for seating arrangements at airports and train stations.
Cassandrich@SwiftOnSecurity Best part of Twitter dying is getting to repost all the shitposts like they're new.
Elias Probst@SwiftOnSecurity they didn't have infrared and CCD sensors for navigation back then, but used c-rays until alternatives became viable.
