Very worried about our problems in the U.S. (and wishing it was not happening.) Hoping to get back to tweeting about making things including electronics.

🚨Crews at risk in the Gulf🚨 Just heard from a crewmember on one of the 3,200 ships stuck in the Persian Gulf. A ship called the local port authority requested permission to dock as they had run out of water. They were denied permission! Multiple ships are in the same condition, with stores, food and fuel running low. Ports are overwhelmed and security is such that they are refusing permission for ships to dock. Crews cannot get off and reliefs cannot fly in. What is being done to address this matter @POTUS @SecWar @SecDuffy @DOTMARAD @IMOSecGen @IMOHQ.

JUST IN: Bloomberg is reporting that Donald Trump Jr. invested in Vulcan Elements at a $200M valuation in August. In November, the Pentagon announced that it was awarding a $620M loan to Vulcan. Vulcan is now reportedly valued at $2 billion. 900% gain in just months if true.

@i2cjak @zackslab Some people care about the tool selection because they care about the continuity of the design using established tool choices. Especially if they have multiple business processes or staff dependencies already.

BREAKING: DOJ officials are reportedly struggling to figure out how Jared Kushner having no actual government job while making secret plans and deals with Israel our national security officials don't know about that dragged us into an unpopular war isn't "textbook treason."

WHOA. Lewandowski is accused of demanding fees from a private prison company to steer them ICE contracts, at a time when he was widely known to be running DHS on Kristi Noem's behalf. Congress should conduct a full and bipartisan investigation into this.

Democrat politicians are now stuck defending two very unpopular issues. The defunding of DHS, and the opposition to voter id. I'm not sure how they get out of this hotbox unscathed.

@MoonBaseSpaceX @DerrickEvans4WV Was expanding on your comment. GPS is specifically the US operated system; other systems transmit their own signals and they all work independently of the others. GNSS receivers now can work with those other systems, not just GPS.

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…

@DerrickEvans4WV After further research, modern smartphones use ALL types of global positioning services. it doesnt rely on 1, USA is not "funding everyone for free" its a universal free service that USA, Europe, Russia and China broadcasts that anyone can use. Dont pretend USA is special

@DerrickEvans4WV Many responses to this reveal a lot of short-sighted self-centered scarcity mindset. We pay to maintain it as it enables quality of life and economic improvement on top of being an important military asset. GPS SA was turned off precisely because it made more sense to share it.

Let me get this straight. The federal government held a legal auction for the right to build offshore wind farms. A company won those auctions fair and square, paying nearly a billion dollars into the U.S. Treasury. The projects went through years of review. Courts repeatedly upheld their legality. Everything was above board. Then the Trump administration tried five separate times to kill other wind projects in federal court and lost every single time. Judges reviewed the administration’s supposed “national security” justification and weren’t persuaded.  So now they’ve landed on a new plan: pay the company nearly ONE BILLION DOLLARS of your tax money to just walk away. Because, and I am not making this up, the president thinks offshore wind turbines are ugly and claims without evidence that they “drive whales crazy.”  He’s been nursing this petty grudge since 2012, when he tried to block a wind farm visible from his golf course in Scotland. Fourteen years later, American taxpayers are footing the bill for it. This is stupid policy. It’s fiscally reckless, strategically blind, and driven entirely by a personal vendetta rather than any coherent vision for American energy or competitiveness. Meanwhile, China is racing ahead, building offshore wind at a staggering pace and positioning itself to dominate the global clean energy economy for decades to come. None of this is America First. nytimes.com/2026/03/17/cli…

Rep. Mike Levin@RepMikeLevin·
This is unhinged. The President of the United States went on a late-night rant, making clear he believes the Supreme Court justices he appointed owe him their loyalty and should always rule in his favor. The President of the United States is openly attacking the independence of the judiciary, the very institution that stands between every American and unchecked executive power. Courts don’t work for the President. They work for the Constitution. And a president attacking the judiciary for doing its job is telling you he believes he is above the law.

I find it ironic that Trump's efforts to kill solar and EV encouraged buyers to rush to get them while the tax credits were available; and now, the disruption in the oil market is highlighting the benefits of solar and EVs.

@Real1JMT @NYCMayor The bracket is between 9 months and 2 years... It took 4 months for my house to be remodeled - an already built home - so a year doesn't sound so bad. Besides, construction is the largest part of the process -- that time varies upon the builder's actions.

If you own a home with a basement, attic, or backyard, chances are you’ve thought about using it to earn a little extra income or as space for a loved one. We want to make it as easy (and affordable) as possible for you to do that. NYC recently legalized ADUs — but for too many New Yorkers, they’re still tied up in bureaucracy and expense. We're fixing that. Our new toolkit at nyc.gov/aduforyou includes preapproved building plans and a financing calculator so you can get right to building. If we want New York to remain a city for everyone, we have to make it easier for homeowners to stay here. ADU for You will do just that.
