Explaining to the boss why the project isn't done yet, "the trajectory of the agentic development over at least the last four months hasn’t really accelerated in the way that we expected."

I don't know whether to make a ST:TNG joke or a Star Wars joke.

I got very lucky with lighting and a passing storm once, which produced this painting-like photo.

Same here. Also, after clicking to embiggen, there seems to be no way to see the alt text. (In the older versions, such as on sfba.social, hovering over the big image shows the alt text.)

That's not enough. You also have to solve a "Raptcha" challenge, like picking all the loaves and fishes in a grid of photos.

Looks like the file as transferred is small (a compressed string of a repeated letter) and so only detrimental when unpacked at the downloading host.

He aspires to be the Harry Lime of our times:
"In Italy, for thirty years under the Borgias, they had warfare, terror, murder and bloodshed, but they produced Michelangelo, Leonardo da Vinci and the Renaissance. In Switzerland, they had brotherly love, they had five hundred years of democracy and peace – and what did that produce? The cuckoo clock."

And nobody can claim that protestors are being "bused in".
Who would bus 4000 people into Coupeville WA (per recent boost)?

A 'step in the right direction' sounds like faint praise.
Trump, by contrast, called it 'a maxed-out deal'.
Not knowing anything specific about the deal, this sounds like Farage is grumbling, but doesn't want to be seen as breaking with Trump.

Do not go viral into Mastodon,
Good toots should pique and charm at close of day;
Mute, mute against the searing blast, go on.

"Starting to think about keeping all my data in the clod."
"You mean the cloud? isn't that risky these days?"
"No, I mean a micro SD card jammed into a clod of dirt."

What happens to the frequencies used by VoA around the world? Can countries reclaim them and offer them to an alternative operator? Wikiradio? Hams?

Also, make sure to get your corvid booster. Always boost corvids.

I can set my terminal (xfce4) to use a blinking or non-blinking "I-beam" as they call it. Its movement is not related to the mouse.
Similarly, LibreOffice has a blinking I-beam text cursor.

Are the vertical bars that live in the spaces between letters so bad?
(I guess that's called an I-beam?)

I propose, in memory of "Ask Jeeves", an "Ask Bertie" search engine. Never knows anything important, just random cricket stats and minor nobility gossip, but willing to speculate charmingly about whatever you ask.

Now I am imagining a sort of low-
