@RoKhanna Where are you getting a collage education for only $500? It might pay for a month or two of childcare. Your math isn't mathing.

$200 billion would pay for free college for every American, $10 day childcare, 1000 new trade schools, the 40% federal share of special needs education and a lot more. What are we even doing here? MAGA is now Iran first?

@DrEricDing Fun fact. The magnets used in MRIs use closed loop helium refrigeration designs. They do not continuously consume helium.

FUN FACT—helium cools the superconducting magnets in more than 14,000 MRI machines used in hospitals worldwide. We lost the largest helium extraction plant in the world in Qatar. US reserves running low. Helium cannot be produced de novo. Any helium escape is permanent.
Shanaka Anslem Perera ⚡@shanaka86

Helium is the only element that escapes Earth’s atmosphere permanently. Once released, it rises through the troposphere, passes the stratosphere, and leaves the planet. It cannot be manufactured. It cannot be synthesised at industrial scale. It accumulates over billions of years in the same geological reservoirs as natural gas. And one third of the world’s supply just went offline because Iran hit the facility that extracts it. Qatar produced roughly 63 million cubic metres of helium in 2025, accounting for 30 to 36 percent of global supply from a total of approximately 190 million cubic metres. QatarEnergy’s three large helium purification plants at Ras Laffan form the world’s biggest helium production base. When LNG production stopped after Iranian drone strikes on March 2 and the subsequent missile damage on March 19, helium extraction stopped automatically because helium is recovered during natural gas liquefaction. You cannot produce helium without producing LNG. The byproduct dies with the primary product. Spot helium prices have roughly doubled since the crisis began. Industry consultants warn that prolonged disruption could push contract prices toward $2,000 per thousand cubic feet. A major industrial gas supplier has already begun assessing customers a helium surcharge. Phil Kornbluth, the most cited helium market consultant, stated the assessment directly: the world cannot compensate for the loss of a third of its helium supply. South Korea imports 64.7 percent of its helium from Qatar. SK Hynix and Samsung operate high-volume fabs producing the DRAM and high-bandwidth memory that power every AI accelerator, every data centre GPU, and every cloud computing cluster on Earth. Helium cools silicon wafers during fabrication. It serves as a carrier gas in deposition and etching tools. It enables leak detection in vacuum systems. Modern extreme ultraviolet lithography requires helium-cooled environments for precise temperature control. Without helium, the fabrication process degrades or stops. SK Hynix and Samsung hold two to three months of helium inventory. Two to three months is not a buffer. It is a countdown. If Ras Laffan remains offline beyond that window, South Korean memory production faces rationing. TSMC in Taiwan is somewhat more diversified but still uses Qatar-linked supply chains. The entire AI hardware supply chain, from HBM3E memory stacks to advanced logic chips, sits inside helium-dependent ecosystems. Beyond semiconductors, helium cools the superconducting magnets in more than 14,000 MRI machines operating worldwide. It pressurises rocket fuel tanks and purges propulsion systems in aerospace. CERN’s Large Hadron Collider depends on helium cryogenic systems. There is no substitute for helium in any of these applications at industrial scale. The United States and Qatar together account for more than 70 percent of global production. The US federal helium reserve and private suppliers offer partial relief, but global prices and spot availability are still governed by Qatar’s market share. Japan’s Iwatani has drawn on US reserves. Canada and the Rockies are seeing renewed investor interest. None of this replaces 63 million cubic metres in weeks. The war hit uranium first. Then oil. Then nitrogen. Then water. Then plastic. Then medicine. Then sulfur. Now helium. Eight layers. Each one deeper. Each one closer to the infrastructure that sustains modern civilisation. The chip that processes your data, the magnet that scans your body, and the rocket that launches your satellite all depend on an atom that leaves the planet when you lose it. open.substack.com/pub/shanakaans…

@boroscq @PumaChairo 4:3 doesn't have to be a crop, either. It just is when they shoot 16:9 or other variants. They could shoot 4:3 if they wanted, and then crop to 16:9.

El 4:3 era el estándar técnico de su tiempo. El formato panorámico fue la respuesta del cine para diferenciarse de la televisión y ofrecer más campo horizontal. El IMAX no es un recorte disfrazado, en muchos casos es más imagen, solo que hacia arriba y abajo. Lo que pasa es que estamos en la época del 16:9, que ya se ha vuelto lo normal, y donde cualquier cambio nos parece raro o sospechoso. La clave no es el formato, es el uso que se hace de él. Cuando está al servicio de la escena, genial. Pero cuando se vende como una ventaja, algo falla. No es que nos hayan engañado antes, es el lenguaje visual va cambiando y a veces el marketing se adelanta a la explicación.

The U.S. military is always terrified that the GPS system (which is 12K miles away) can be jammed/spoofed. Interestingly, researchers at Ohio State University discovered they could use Starlink’s signals as a stealth navigation system. Cos Starlink satellites are in Low Earth Orbit (LEO) & fly so fast, their doppler shift is incredibly predictable. By just listening to the pings w/o even having an account, a receiver can calculate its position on Earth within 7.7 meters. This effectively creates a backup GPS that is almost impossible to jam cos there are 1000s of transmitters instead of just 31.
Sawyer Merritt@SawyerMerritt

NEWS: Globe Telecom said it has successfully tested Starlink’s Mobile service in the Philippines, allowing phones to connect in areas with no signal. The pilot was done in Rizal, Batangas, and Bataan, where users were able to send messages, make calls, and use data even without nearby cell towers. "This will be our lifeline, especially during disasters and our complementary coverage in areas where terrestrial network is not available," said Joel Agustin, Senior Vice President for Service Planning and Engineering at Globe. "The service will also address the connectivity requirements of GIDA (Geographically Isolated and Disadvantaged Areas) communities and strengthen coverage across the country's territorial boundaries," he added.

@LinkofSunshine I believe it is mostly a psychological affect. If you talk to someone with a severe nut allergy, they will claim that the nuts smell terrible to them. "Airborne allergies" are just them feeling nauseous because psychologically they're smelling the equivalent of rotten meat.

There is basically 0 hard evidence that airborne allergies exist outside of extremely rare circumstances In one experiment, they just straight up held 29 people 3-inches away from a thing of peanut butter and found not a single one had anything close to a reaction

If we translated an alien language through text alone, the color of their plants would translate as "green" regardless of what frequencies of light they actually reject from their star. All plants in the universe are green, until we can see them ourselves.

Any news article about pollution from plastic bags or other plastic products that does not point out that the US produces essentially zero per capita plastic pollution is ridiculously misleading. You can't even see the US here because it's basically on the x-axis. In a lot of countries, people literally just throw all their trash in the river. That's the plastic problem.

@rexdelay @ProfRobAnderson That's waste. The plastic waste from the US generally does not turn into pollution because the vast majority of it is properly disposed. The graph shows pollution, because many countries don't have proper disposal methods and culture.

@TomWT2 @starcitizenbot The flight suit and helmet would still give best ship control, especially the specialized suits the mentioned that have better G resistance. It's adding armor on top of the suit that would slow you down. But you don't need armor for life support.

@starcitizenbot There should be some thought put into that. I would very much like to see "The Expanse" like preparation for battle with spacesuits/armors on, life support off. Not sure if penalization of ship control in such case would be good option.

@shelvacu @Fintech03 The phase array antenna on the ground station should improve the situation for Starlink, since it could effectively ignore signals that don't come from the sky, and even pick out individual satellites. SpaceX has already tested PNT capability in war zones with active jamming.

@Fintech03 What is different with Starlink is the highly directional phase array antenna. A positioning system built into Starlink receivers, (which SpaceX is already testing, and might be part of Starshield already) would be highly resistant to jamming, able to ignore false signals.

When you stream Spotify to Bluetooth speakers or headphones, the audio comes over the network lossily compressed with Vorbis or AAC codecs, is then decoded on your device to 48 Khz raw samples, then the Bluetooth stack lossily re-compresses it with SBC or AAC codecs before sending it over the airwaves to the speakers. I don’t have “golden ears” to pick apart audio quality like I can with, say, missing gamma correction on texture filtering, but that still hurts my system optimization soul. It is likely over-optimization, but It would be cleaner if there were a way to send bluetooth-ready, compressed audio directly.
