Went for a x-country ski out the front door, down the road, then into the woods.

@harald After all of that bare ground I bet they're finished. ';^)

How much are you willing to pay for a #painting you really like? 🖼️
(Average size, on canvas)Please boost so I can get a general idea from people on Mastodon…🎨🧑🎨

OK, so now we just wait for Trump to go to war against the UK over Chagos Islands. What a year, huh?
Those weird noises you hear from the East are Putin and Xi pissing themselves from laughter.

Troppa "esposizione".
Scelte non compatibili.
Emoticon travisante, ma speranzosa.
No dai non può essere.
Cervello (mio) grullo, statti buono.P.S. sono così di normale, niente sostanze (se non cioccolata al latte a vagoni). Abbiate pazienza

@fucinafibonacci drammaticamente ironico che la soluzione a tutti i problemi complessi sia semplicemente essere se stessi, mandando al diavolo chiunque ti dica chi devi essere o cosa devi fare.
Ma questo a quanto pare non piace quasi a nessuno

@_elena Same here!

@mensrea great advice!
her favorite "toy" is LEGO (hmmm I wonder where she got that from) so I'm teaching her how to have hours of endless fun with the same things that can be rearranged... and I'm teaching her to build things out of LEGO (like toothbrush or pencil holders, etc)... 🤗

Inside Air Traffic Control
It is a movie staple to see an overworked air traffic controller sweating over a radar display. Depending on the movie, they might realize they’ve picked the wrong week to stop some bad habit. But how does the system really work? [J. B. Crawford] has a meticulously detailed post about the origins of the computerized air traffic control system (building on an earlier post which is also interesting).
Like many early computer systems, the FAA started out with the Air Force SAGE defense system. It makes sense. SAGE had to identify and track radar targets. The 1959 SATIN (SAGE Air Traffic Integration) program was the result. Meanwhile, different parts of the air traffic system were installing computers piecemeal.
SAGE and its successors had many parents: MIT, MITRE, RAND, and IBM. When it was time to put together a single national air traffic system the FAA went straight to IBM, who glued together a handful of System 360 computers to form the IBM 9020. The computers had a common memory bus and formed redundant sets of computer elements to process the tremendous amount of data fed to the system. The shared memory devices were practically computers in their own right. Each main computing element had a private area of memory but could also allocate in the large shared pool.
The 9200 ran the skies for quite a while until IBM replaced it with the IBM 3083. The software was mostly the same, as were the display units. But the computer hardware, unsurprisingly, received many updates.
If you’re thinking that there’s no need to read the original post now that you’ve got the highlights from us, we’d urge you to click the link anyway. The post has a tremendous amount of detail and research. We’ve only scratched the surface.
There were earlier control systems, some with groovy light pens. These days, the control tower might be in the cloud.

@_elena teach her to modify and upgrade her toys. she'll get used to the idea that the objects she holds are hers and should do what she wants. toys get broken but appliances and software tools are not malleable will not be tolerated later
