75 years ago today, European nations signed this Convention, so the Holocaust could not be repeated. Beware those who want this to end.

@lproven I've read a lot of compelling arguments about how these LLMs will not achieve AGI. However the goal is AGI and the world is currently throwing about twenty percent of GDP at that goal. It's basically a modern day Manhattan project. With that said I would not bet against achieving AGI at some time in the near future.

How AGI became the most consequential conspiracy theory of our time (MIT Technology Review)
The idea that machines will be as smart as—or smarter than—humans has hijacked an entire industry. But look closely & you’ll see it’s a myth that persists for many of the same reasons conspiracies do.
In PostgreSQL we could do:
CREATE TABLE t (a int, b int);
INSERT INTO t VALUES (1, 2), (3, 4), (5, 6);
SELECT t.*
FROM t
JOIN (
VALUES (1, 2), (3, 4)
) v(a, b)
ON (t.a = v.a AND t.b = v.b);
a | b
---+---
1 | 2
3 | 4
Another approach would be an array for a and b:
SELECT *
FROM t
WHERE a = ANY(ARRAY[1, 3])
AND b = ANY(ARRAY[2, 4]);
If you really wanted the 2d array, then there are ways to unpack that and join against it.

After three years and more than 3,100 miles (5,000 kilometers) of sailing in a Viking replica vessel, archaeologist Greer Jarrett from Lund University in Sweden has authored a trailblazing report on Viking seafaring. His work, published in the Journal of Archaeological Method and Theory, suggests that the Viking trade routes were more extensive, decentralized, and offshore than previously believed.

@azonenberg EVs seem to get quoted at about 75% efficiency.
Not sure about the charging losses, but I suspect at higher rates it's not that good.
As good as EVs are getting, the energy density of Petrol is likely still an order of magnitude greater.
Would be nice to see more battery swap approaches to rapid charging, admittedly mechanically complicated.
Standard petrol pump can do about 50 litres per minute.
Energy in 1 litre of petrol is about 33MJ.
My basic maths would ~27MW of energy transferred each second.
Assume 30% engine efficiency, still talking say 9MW.
Which seems at least an order of magnitude over the best EV charger.

For the first time since I started attending FOSDEM in 2010, there will be no PostgreSQL Devroom in 2026. Feels unbelievable for one of the defining open source projects of the last decade.
At least there's #FOSDEMPGDay.

@ChrisMayLA6 first time I saw The War Game was in Hack Green Nuclear Bunker, which only made it more poignant.

Just a few sleepless nights from Chris Ellis… and the Slonik timer is ready to make its debut at the PGConf.EU lightning talk session at 16:15! 🐘⏱️✨
Isn’t it the coolest thing in Postgres since the Slonik mascot suit?

A small gesture of big appreciation ❤️
Each PGConf.EU speaker and organiser will receive a handmade Latvian wooden tray, crafted by Koka Lietu Darbnīca, a local workshop run by artisans Roberts Leitāns and Evija Rukmane. https://kokalietudarbnica.lv/lv/
Crafted from sustainably sourced Latvian wood, each tray carries the warmth, texture, and craftsmanship that reflect the spirit of this year’s host country. 🇱🇻

On this day in 1971, the U.K. successful reached orbit using the Black Arrow launch vehicle lifting the Prospero satellite to orbit from Woomera, Australia. The U.K. remains the only country to reach orbit after already cancelling their launch programme. https://en.wikipedia.org/wiki/Black_Arrow

The idea that the public sector is inefficient and wasteful, while the private sector is tight and spendthrift, is complete and utter bollocks. This nonsense notion has been ruination of the UK for the past 40 years.
@tig sounds very much like my impulse purchase Jaag, which has been in the garage for a while having rust and previous bodges repaired.
@tig I've been enjoying Look Mum No Computer's Austin Seven project.
@tig how do you hold the rust together without stickers?
