Open source maintainers already had enough to worry about before the ongoing agentic AI revolution... my thoughts on recent AI-induced problems in open source development: www.youtube.com/watch?v=bZJ7...

Great video on how extreme-UV lithography works and why ASML’s machines are so crucial to chipmaking:

On December 5, 2022, a camera on board the uncrewed Orion spacecraft captured this view as Orion approached its return powered flyby of the Moon. Beyond one of Orion's extended solar arrays lies dark, smooth, terrain along the western edge of the Oceanus Procellarum. Prominent on the lunar nearside Oceanus Procellarum, the Ocean of Storms, is the largest of the Moon's lava-flooded maria. The lunar terminator, the shadow line between lunar night and day, runs along the left of this frame. The 41 kilometer diameter crater Marius is top center, with ray crater Kepler peeking in at the edge, just right of the solar array wing. Kepler's bright rays extend to the north and west, reaching the dark-floored Marius. By December 11, 2022 the Orion spacecraft had returned to its home world. The historic Artemis 1 mission ended with Orion's successful splashdown in planet Earth's water-flooded Pacific Ocean.

Fifty three years ago, in December of 1972, Apollo 17 astronauts Eugene Cernan and Harrison Schmitt spent about 75 hours on the Moon exploring the Taurus-Littrow valley, while colleague Ronald Evans orbited overhead. This snapshot from another world was taken by Cernan as he and Schmitt roamed the lunar valley's floor. The image shows Schmitt next to the lunar rover parked at the southeast rim of Shorty Crater. That location is near the spot where geologist Schmitt discovered orange lunar soil. The Apollo 17 crew returned with 110 kilograms of rock and soil samples, more than was returned from any of the other lunar landing sites. And for now, Cernan and Schmitt are the last to walk on the Moon.

The reason we know Radiation causes bit-flips in DRAM is pretty hilarious.
In the late 70s, Intel Ram was occasionally producing soft, uncorrectable errors.
Turns out, the ceramic packaging on the chip itself had a little bit of Uranium.
You know, as one does.

Everyone knows that the x86 ISA is big.
Modern CPUs have ~1000+ mnemonics. Guess how many make up 90% of compiled C/C++ code?
TWELVE. I'm not kidding.
The question is…what if we shrank it?
Birth rates are falling more steeply among progressives than conservatives
Interesting chart. It may help explain the current right-wing shift around the globe. With all the reservations, intergenerational transmission of values cannot be completely ignored.

Refusing to "trust the experts" is meant to be a brave, responsible position.
But (as Carl explains in the thread) there is too much knowledge in the world. You have to trust *somebody*, much of the time.
If you have no trust in experts, you end up trusting the idiots.
