If anyone is upset that people are cheering McConnell’s declining health, remember what McConnell said to Biden about the enormous benefit a bill would provide to all citizens: "You must be under the mistaken impression that I care.”

So, let me summarize. In the last 24 hours, Ukraine hit: an oil refinery and a nitrates refinery Russia hit: an arts museum and an old lady of 73 y.o. (targeted FPV strike)

#OTD in 1959, Submarine Voyage opened at Disneyland. The "subs" were built with advice from General Dynamics' Electric Boat Division and named for actual Navy subs. Walt boasted he had the 8th largest sub fleet in the world. During the 1950's and 60's guests could even see "live mermaids" swimming in the lagoon around the subs. #SubmarineSunday

When a family in Vermont reached out to Baltimore restaurant owner Steve Chu asking for the recipe of a favorite dish enjoyed by their terminally ill loved one, they expected instructions. Instead, they received something far more meaningful. Steve Chu, co-owner of Ekiben, loaded his truck with ingredients and drove nearly six hours from Baltimore to Vermont. Along with his team, he set up a makeshift kitchen outside the woman's home and prepared her beloved meal fresh on-site. They refused payment and simply wanted to bring comfort and happiness during a difficult time. What began as a request for a recipe became an unforgettable act of compassion, proving that kindness often travels much farther than anyone expects.

Trump looses any influence the U.S. may have in foreign policy.
Putin’s advisor Ushakov says Trump, in a conversation with Putin today, promised to put pressure on the Europeans and Ukraine during the G7 summit, and otherwise, to accept Russian peace conditions. (Uncommon in a readout to speak on behalf of the interlocutor, by the way.)

Loud fireworks at 11:30 pm is ridiculous. I bet all those pets love it too. This president does not give a hoot about anyone or anything else. Ever.
Meanwhile, in DC: residents are being advised of a loud fireworks show starting at *11:30 pm.*

Dlaczego czasem trzeba „uśmiercić” rezonans magnetyczny? Wiecie co to jest quench i dlaczego jest jednym z najbardziej spektakularnych zdarzeń związanych z rezonansem magnetycznym? Sercem rezonansu MRI jest potężny nadprzewodzący magnes. Aby działał, jego cewki muszą być schłodzone ciekłym helem do temperatury bliskiej zeru absolutnemu, czyli około -269°C. W takich warunkach prąd może płynąć bez oporu, wytwarzając niezwykle silne pole magnetyczne. Quench następuje wtedy, gdy część magnesu nagle traci nadprzewodnictwo i zaczyna się ogrzewać. Powstałe ciepło błyskawicznie rozprzestrzenia się na kolejne fragmenty cewek, wywołując reakcję łańcuchową. W ciągu kilku sekund pole magnetyczne zanika, a ogromne ilości ciekłego helu gwałtownie zamieniają się w gaz. Towarzyszy temu charakterystyczny huk oraz pojawienie się gęstej, zimnej mgły. Dlatego pracownie rezonansu wyposażone są w specjalne rury odprowadzające hel na zewnątrz budynku oraz procedury bezpieczeństwa chroniące personel i pacjentów. Czasami quench jest uruchamiany celowo. Przykładowo, gdy do pomieszczenia rezonansu zostanie wciągnięta ciężka metalowa butla z tlenem i utknie przy magnesie, może stanowić bezpośrednie zagrożenie dla ludzi. W takiej sytuacji jedynym sposobem na szybkie wyłączenie pola magnetycznego może być właśnie awaryjny quench. To jednak bardzo kosztowna operacja. W nowoczesnym rezonansie znajduje się nawet około 550 litrów ciekłego helu, a jego utrata oznacza wielotygodniowy przestój i koszt napraw liczony często w setkach tysięcy złotych. Dlatego quench traktowany jest jako ostateczność – ratowanie ludzi jest ważniejsze niż sprzęt wart kilka milionów. Tutaj macie kontrolowany quench

Trump's emergency plea to the DC Circuit to stop removal of his name from the Kennedy Center included this odd reference to a bylaw that had never been mentioned before in the litigation. It's looking increasingly like it was passed last week—and maybe on Thursday, the day before the petition.
Replying to @rparloff
Here Trump asserts that center’s “trustees” passed a poison-pill bylaw that requires return of donations if his name is ever removed. AFAIK this has never been alleged before in the litigation. If true, it's another shocking indictment of his board of toadies. 2/5

In mechanical engineering, cutting deeper threads does not make a bolt stronger. In fact, it does the exact opposite. There is a precise point of diminishing returns where adding thread depth significantly weakens the fastener without providing any extra holding power. The strength of any threaded connection depends on a delicate balance between thread engagement and the integrity of the bolt core. The Core Diameter Problem The most critical dimension of any threaded fastener is its minor diameter the thickness of the solid metal cylinder remaining at the very center of the bolt. Structural Integrity: When you cut threads deeper, you are effectively carving away this central core. A bolt with excessively deep threads has a much thinner minor diameter, drastically reducing its cross-sectional area and making it highly susceptible to snapping under tension or shear force. Stress Concentration: Deep, sharp thread roots act as severe stress risers. These are microscopic points where mechanical stress accumulates during loading, leading to fatigue cracks that can cause the bolt to fail unexpectedly. The 75% Rule To prevent these failures, standard engineering practice relies on the 75% thread engagement rule for standard fasteners.

🔥 INCREDIBLE! Japanese hospitals are revolutionizing eye care. A grueling 15-minute glaucoma test is being replaced by a lightning-fast AI scan that takes just 3 seconds! This massive leap allows doctors to detect the disease accurately and start treatment years earlier.

Today the flags fly at half-mast. On the night of 14 June 1941, doors were knocked in the dark across Estonia. Mothers were given minutes. Children clutched whatever they could carry. More than 10,000 people — among them infants and the elderly — were loaded into cattle wagons and sent east, into the cold, into silence. Men were torn from their families and sent to camps from which most never returned. They committed no crime. Their only offense was being Estonian, being educated, being landowners, being someone the regime decided to erase. We lower our flags today not out of habit, but out of memory. For the empty chairs at kitchen tables. For the letters that stopped coming. For the graves that have no markers in the Siberian earth. A nation that forgets its grief forgets itself. So we remember. We say their names. We teach our children why this day is quiet. Mälestame. We remember. 🕯️🇪🇪

Google hid a fully working flight simulator inside Google Earth back in 2007 and never told anyone. You unlocked it with a secret keystroke: Ctrl Alt A. No menu, no announcement. One user stumbled onto it, the combo spread, and it got popular enough that Google made it official the next year. Two planes, an F-16 and a Cirrus SR22, flying over real satellite imagery of the entire planet. Then it stayed locked inside the downloadable desktop app for 18 years. The browser version was a stripped-down viewer that couldn't run it. Today that changed. Here is the part that makes it impressive. A flight simulator is the single hardest thing you can ask a 3D map to do. Panning is easy, the software has all the time it wants to load the terrain ahead of you. Flying low and fast strips that away, forcing it to fetch, decompress, and render the world faster than you are crossing it. The hardest possible job for every part of the system at once. So "just for fun" is carrying a lot of weight in that sentence. Getting this to run in a browser tab is the cleanest proof that the web version finally matches what used to need a desktop app. The toy is the benchmark.
Prepare for takeoff. ✈️ Flight simulator is now available globally on web to all users. goo.gle/4fBYnWO We've recently added many our most powerful professional desktop features to web. Elevation profiles, new import types, but there's always been one other feature you've been asking us to add to the web version of Google Earth, just for fun... Where will you fly? Share your best maneuvers, views, and flyovers with us!

Ugly Russian orc enjoying his miserable life on the beaches of Barcelona. He happy the police didn't come for him but for some other guy. He says he has drugs on him and intends to sell the drugs. "Russian mafia rules", he adds at the end. Europeans keep floodgates open for Russian scum, why?
