@impossible_eng @BellikOzan Tells me everything I need to know. You clearly have never navigated a space where competing patents are an issue. Stop the armchair quarterbacking, you are an engineer who’s never dealt with this type of legal issue.

Pet peeve of mine is people patenting glaringly obvious stuff half the people in the field have been assuming, talking about, and actively working on. This is worse than patenting barge landings.

1/ $ASTS: 🚨AST SPACEMOBILE HAS ALREADY SOLVED THE HEAT DISSIPATION ISSUE FACING POTENTIAL SPACE DATA CENTER APPLICATIONS AST SpaceMobile's patented micron tiles act like giant radiators that dissipate heat generated from the FPGAs/ASICs that are embedded in each tile. You can easily imagine AI-specific GPUs, TPUs, ASICs and/or FPGAs embedded into a micron w/ solar array on one side and the phased array removed. 🔍Patent Number: US 11,021,270 B2 Title: Thermal management system for structures in space Date of Patent: June 1, 2021 Assignee: AST & Science, LLC Inventors: Abel Avellan, Huiwen Yao 🔍This patent focuses on the thermal control of the company's satellites (likely the "BlueWalker" and "BlueBird" series). AST SpaceMobile's satellites are unique because they are essentially massive, flat phased-array antennas in space. 🔍The patent describes a system to manage the extreme heat generated by the electronics while the satellite is in orbit. Key features include: ✅Layered Design: It details a structure where a "solar layer" (solar panels) is connected to an "antenna layer." ✅Heat Dissipation: It outlines how electronic components (like the Front End Modules or FEMs) are integrated and how heat is transferred away from these critical components to keep the satellite functioning within safe temperature ranges in the vacuum of space. ✅Structural Integration: The thermal management is built directly into the structural tiles of the satellite, allowing the satellite to remain lightweight and foldable for launch while acting as a giant radiator once deployed.

I'd highly encourage Canadians to AVOID ALL TRAVEL to the United States. Not out spite, but out of safety. Even Canadian citizens with proper documentation are being arrested and sent to detention camps!

@jeffdech @BellikOzan Not really no. Lots of small shops work on satellite tech. I've worked at several.

@impossible_eng @BellikOzan If you are working on satellite tech and need a patent invalidated to have freedom to operate, you have that kind of war chest or you have no idea what you are doing.

Unpopular opinion: A private business has the right to refuse service to anyone for any reason. That applies to the lesbian couple who declined to serve Governor Sarah Sanders just as much as it did to the Christian baker who refused a gay couple. Rights don’t depend on which side of the political aisle you’re on.
Right Angle News Network@Rightanglenews

BREAKING - It’s been revealed the Arkansas bakery that kicked out Gov. Huckabee Sanders because her “politics made them feel unsafe” is run by two butch lesbians, Jill McDonald and Wendy Shay. It would be a shame if people gave their business some attention.

@BehizyTweets @SecScottBessent This is a proxy war with China. The price differential minus added friction will be roughly neutral to Iran but more costly to China since they can’t buy the oil as easily. This is a bet that Iran can’t make enough gains and China will ultimately lose.

@SecScottBessent Can someone explain to me how unsanctioning Iran's oil so they get full price for it & efficient transactions is actually super bad for them? Lol.

Treasury Secretary Scott Bessent
Iran is the head of the snake for global terrorism, and through President Trump’s Operation Epic Fury, we are winning this critical fight at an even faster pace than anticipated. In response to Iran’s terrorist attacks against global energy infrastructure, the Trump Administration will continue to deploy America’s economic and military might to maximize the flow of energy to the world, strengthen global supply, and seek to ensure market stability. Today, the Department of the Treasury is issuing a narrowly tailored, short-term authorization permitting the sale of Iranian oil currently stranded at sea. At present, sanctioned Iranian oil is being hoarded by China on the cheap. By temporarily unlocking this existing supply for the world, the United States will quickly bring approximately 140 million barrels of oil to global markets, expanding the amount of worldwide energy and helping to relieve the temporary pressures on supply caused by Iran. In essence, we will be using the Iranian barrels against Tehran to keep the price down as we continue Operation Epic Fury. This temporary, short-term authorization is strictly limited to oil that is already in transit and does not allow new purchases or production. Further, Iran will have difficulty accessing any revenue generated and the United States will continue to maintain maximum pressure on Iran and its ability to access the international financial system. So far, the Trump Administration has been working to bring around 440 million additional barrels of oil to the global market, undercutting Iran’s ability to leverage its disruptions in the Strait of Hormuz. President Trump’s pro-energy agenda has driven U.S. oil and gas production to record levels, strengthening energy security and lowering fuel costs. Any short-term disruption now will ultimately translate into longer-term economic gains for Americans – because there is no prosperity without security.

Which demographics of Canadians are leaving Canada? >67% of the are 20-44 year olds. >3x more likely to be in Sciences than avg population. >31.1% have a masters degree. >61.4% left to the US. In other words, it's Canada's youngest, most talented and educated population.

@robinhanson I’m confident that Feynman believed truth was only obtained at the three sigma level and that everything else was a floating belief. That explains this video and what your opinion of that divider is will determine your response.

@willreil Sure, if you only need jellybean parts it’s fine. If you need real, performant ICs this calculation falls apart.

All the components for the cheap PCB project have arrived from AliExpress. The component cost per board is: 2 x $0.006 per resistor 2 x $0.012 per capacitor 2 x $0.030 per diode 1 x $0.038 per 555 —— = $0.134 for components + $0.106 per PCB —— Thats only $0.24 per board, wow!

@blind_via Every hardware designer I know in the valley chooses Altium. Other software is for startups saving a buck or people who aren’t serious. I’ve asked around, my company would be on Altium if weren’t trying to save a buck.

@jeffdech Altium is ok, haven't used it in a few years. Most customer driving my primary work use Pads Layout and Xpedition. But I used Altium for a lot of designs back in the day.

KiCAD's "competitors" are PCB Layout software that is free. Basically, all layout tools that fall into the free category, are owned by the electronics manufacturers and they are trying to influence you to purchase their products through the way they have designed their software.

Honestly, Apple should be world-leading when it comes to releasing American open source models. They have the cash. They have every incentive to commoditize their complement, most users are buying Mac Studios to run Chinese OSS models. Major security risk. @tim_cook plz fix

@yacineMTB There are lots of them, scattered in design docs all across the internet but freely available. You could collate them, maybe with an LLM. That’s probably a good project to do.

i need to properly layout this thing and i have no idea how instinctively the positions of each thing should go according to some rules. EEs have these rules in their head because they live in the 90s. what are these rules?
