Si te *huelo* la menor conspiranoia u otra patología cognitiva la conversación se corta en seco y la relación también. Las ideas se examinan a la luz de la evidencia. O se guarda silencio.

If you "vibe check", congratulations! You've found the source of all the "bad vibes". Now keep your health and go away.

Ready to take a deep dive into the science from humanity's three asteroid sample return missions: Hayabusa, Hayabusa2, and OSIRIS-REx? 🪨🛰️

Written for non-geophysicists (like me!), and those new to the field who don't yet ask to "pass the halite" at the dinner table, this review takes you on a whirlwind tour of the three missions and what was found when the samples crashed back to Earth:

The science from asteroid sample return missions

To date, three samples from near-Earth asteroids have been delivered to Earth by Japan's Hayabusa (2010) and Hayabusa2 (2020) missions, and the United States OSIRIS-REx mission (2023). Free from terrestrial contamination, these pristine materials provide new opportunities to investigate planetary formation processes, the delivery of organics and water to the early Earth, and the nature of potentially hazardous asteroids. As analysis of the asteroid samples proceeds in laboratories around the world, we visit each of the missions, review the initial scientific findings, and explore the value of sample return in understanding our origins and protecting our future.

I despise PGA chip packages that are not designed with a keyed pin arrangement, to prevent socket misainsertion at a rotation of 90, 180, or 270 degrees.
Motorola did that with the MC68000RC, MC68010RC, MC68012RC, MC68440RC, MC68450RC, MC68881RC, MC68882RC, and probably more.
Intel did it with the A80286, A80386, A80387, and A80960KA/KB/MC/XA, and probably more.
I just noticed that National Semiconductor did it with the NS32381 floating point coprocessor.

Tengo aquí al lado una reunión de víctimas de violencia de género y sus mediadoras. Estoy oyendo unas cosas, que al que me diga que "feminismo pa qué, las mujeres están ya por encima y se aprovechan del sistema y pobrecitos hombres mimimimi" LE REVIENTO LA PUTA CARA.

Morning, fuckers.

Today Luigi Mangione is 28 years old. It's his second birthday spent in prison.

I don't know what's your stance on political violence and I'm not discussing mine here: what I do care about is the fact that incarceration is torture. I visited enough persons deprived of their freedom to know that.

He can receive and write letters. Here's what you need to know about that:

If this inspires you to care for other prisoners, ones you may even visit, so much the better. Remember: no one is free until everyone is free.

And this should go without saying, but I'm not interested in any theories or even experiences justifying the statu quo. Go live your fascist fantasies elsewhere.

Due to the extraordinary volume of inquiries and outpouring of support, this site was created and is maintained by Luigi Mangione’s New York legal defense team to provide answers to frequently asked questions, accurate information about his cases, and dispel misinformation. The intent is to share factual information regarding the unprecedented, multiple prosecutions against him.

🚨 The UK says it wants to "protect children online"

Yet, forcing EVERYONE to verify their age won't stop harm - but put all of us under surveillance.

Today, we've signed an open letter together with @mullvad @Tor @mozilla & others to stop #AgeVerification in the UK 💪

Don't make it worse by asking if they’re drinking enough water.

I'm still going to write code to solve problems I care about but I need to rethink licensing and distribution. Making my code public may actively harm me - hosting costs, time & effort defending against AI scrapers, attribution laundering, plagiarism, all devaluing the skill I use to put food on my table. Plus the morale damage that comes from knowing that work I put care and effort into is being ground into a barely recognizable paste to fund psychofuckwit nazi oligarchs that deluded themselves into believing a box of anxious electrified sand is a god.

If someone else was _just_ making money off my work it wouldn't be nearly as bad. But no, it has to be shoved into the LLM blender and extruded as "AI search results" that actively makes everyone else stupider, prevents people from finding canonical and trustworthy sources of information, actively prevents people from finding experts or recognizing expertise. That high velocity StupidityAsAService is already infecting every piece of computational technology that touches the internet. Code is churned out faster and faster, quality is plummeting in free fall, and every organization that dove headfirst into the empty pool that is AI is sweating bullets that their end of the pool will start filling up before they faceplant into the concrete.

I swear, computer programmers are some of the most gullible, delusional, arrogant, and just plain stupid people on the planet. And we're stuck with them shitting up everything they touch.

@foone In school I had a Commodore 1526 printer that had one (1) re-definable character that you could redefine once (1ce) per line and I wrote a printer driver to use it as a graphics device and if I remember correctly it ran at a little under 30 minutes a page, resulting in a blazing two pages per hour

@olivia ok, let's see if i can explain this succinctly.

If you heat up a piece of ceramic pottery with a layer oxidized glaze (or copper) on its surface, and while it's still red hot, you bury in a combustible material (in this case, sawdust), and restrict the supply of oxygen, the sawdust breaks down from the heat, and the carbon atoms in it become desperate for the oxygen that they can't get because of the lack of air supply.

So, they start pulling oxygen from wherever they can, including from the surface of the pottery. So, the copper oxides end up with their oxygen atoms stripped away, leaving only metallic copper behind. This is called reduction and it's the opposite of oxidation.

This same basic reaction is used in gas-fired kilns if you want a reducing atmosphere. Once everything is extremely hot, the air vents are partially closed, but you keep pumping natural gas into the kiln. When the gas hits the hot pottery, it starts ripping oxygen away from the molten glaze. This is done to get the beautiful colors that are only possible in a reduction atmosphere
