I just sent a donation. I also wanted to tell you that I turned on my radio while driving home this evening and the local station (KQED in San Francisco) had a piece about Ukraine and drones and a quote from YOU. Imagine my surprise! Well done!

Maybe you could pick some challenging examples and we could have a video chat? I suspect you’ll pick it up with a little help.

Fascist Failure The State of Trump

What is the state of Trump? He is failing at fascism. For Trump to succeed in his fascist transition, he needs a bloody, popular, victorious war. And that is out of his reach. The State of the Union was full of fascist atmospherics. It was also blowhard exhaustion

US government has complained Ukraine might have hit "economic interests" in Kazakhstan.

However when russia has reduced American businesses in Ukraine to ashes, they've had nothing to say.

Opinion | When Will This War End? The Question Is Meaningless.

"I asked a crane operator, Yevhen Bilousov, when he thought the war might end. The question itself was meaningless, he told me, 'because everything depends not on when but on how the war ends.'"--Nataliya Gumenyuk

Impressive. Apologies on behalf of Google if it mangled my sentence. And thanks for your work. I just finished Let Our Fame Be Great, and was mightily impressed.

Melanie Kowal | Substack Writing about family history in Galicia: records, roads, epidemics, women’s lives, and what survives between the lines. Ukrainian diaspora research, culture, and care — not just dates and wars.

One of the Q's I see asked the most on #FamilyHistory research in our part of #Ukraine is : where to begin? I've started to write about this here. Sub is free and I will be adding more. Please share if you know someone who'd find it useful.

Maybe someone should convince him that under Donbas there is abundant cryptocurrency to be saved from the russkies.

When I first learned about the Roman practice of damnatio memoriae I thought it weird. But now I totally get it.

How time changes people, especially politicians. Rubio in 2014 was an entirely different person, a true republican.

In an amazing coincidence, the size of Trump’s name on the Kennedy Center is exactly equal to the total size of all the redactions of his name from the Epstein Files.

There’s a recurring russian propaganda loop around #Ukraine that’s worth spotting — once you see it, it’s impossible to miss. Its especially bad on Twitter right now🧵

Airbus update on A320 Family precautionary fleet action Analysis of a recent event involving an A320 Family aircraft has revealed that intense solar radiation may corrupt data critical. Read more.

The official Airbus statement talks about solar-induced radiation corruption. We are at the peak of the 11y solar cycle, which fits. Although our flight was at night so perhaps it could have waited until morning - after arrival.🥱

If so, kudos to Airbus and/or the operators for figuring out the fix so quickly, having all those (presumably unaffected) spares lying around and getting them (and the techs) to the aircraft.

EASA Issues Emergency Directive On A320 Aircraft Investigators identified a critical hardware vulnerability following an in-flight incident.

The interesting question is: what was wrong and how was it fixed? This article suggests a hardware replacement was being done: avweb.com/aviation-new...

During the initial delay I discovered an Eataly in the terminal (JFK T8) with good espresso and excellent filled-to-order cannoli so that time passed very quickly indeed.🏢
