I’m an engineer. That means I was put here to design and build things. The last thing I want to do is harp about a misguided regulatory system, which has turned a providential gift which should lift humanity to new heights into a drag on ratepayers and taxpayers and a haven for parasites and grifters. I need a break. A chorister has asked me if we could build a conventional big PWR in a shipyard. This would combine the low technical risk of a 75 year old technology with the amazing productivity of a world class shipyard. This question gives me a chance to go back to what I should be doing instead of moonlighting as an ineffective JV Jeremiah. //

But we are still below a 100 million dollars for steel and ballast. According to KHNP numbers, all the stuff inside the turbine hall will cost about 400 million. and the the Nuclear Steam Supply System will cost 1.5 billion.\cite{choi-2017} (Both numbers are far higher than they should be.) We are talking about 2 billion dollars for a 1.4 GW plant.

This is all back of the envelope. It will have to be confirmed by doing the actual design. But thanks to recent advances in heavy lift capability, if and only if we go to all steel construction, I’m confident that technically we could build a 1 GW+ Pressurized Water Reactor in a shipyard, and gain the astounding productivity that the world class yards have had to develop in the fiercely competitive environment that they face. We could quickly get back to $2000/kW and less using the same basic technology that the late 1960’s plants used. Build times will start out at around two years and quickly come down to one year. The TG will be the long lead time component.

But this is all dreaming. Shipyard productivity depends on three basics:

1) No one can unilaterally dictate the rules. Everybody involved knows the rules and the rules can’t change in the middle of the game.

2) Total freedom to build the ships the way the yard wants to and change that process as it sees fit, as long as the ships perform to spec. This includes freedom to buy equipment and material from anybody willing to provide it. And freedom to decide on its own quality enforcement system.

3) Intense competition over an extended period, not just between the yards, not just between the yards’ vendors and the vendors’ vendors, but also between the Classification Societies.

We have chosen to not allow these three basics to exist for nuclear power.

Until we build nuclear plants like the Koreans build commercial vessels, attempting to build plants, big or small, in a yard, will accomplish nothing but screw up the yard. Pass the Nuclear Reorganization Act.

Welcome to the Artemis II multimedia resource collection. Here, you can view and download mission photographs, behind‑the‑scenes videos, podcasts, and more. The Artemis II mission—NASA’s first crewed lunar flyby in over 50 years—is a key step toward a long‑term return to the Moon and future crewed missions to Mars.

Dr. Harrison “Jack” Schmitt, 90, an Apollo 17 astronaut who spent three days on the moon in 1972, told The Post this week that there is a superfuel locked within the lunar dust that could provide Earth with an abundance of clean and safe energy for generations.

“I’ve been working on this for many decades — harvesting the light isotope of helium-3 from the moon,” said Schmitt, who is from New Mexico and lives in Albuquerque.

Schmitt is one of just 12 humans to ever walk on the moon, and four who are still alive. Buzz Aldrin, Charlie Duke and David Scott are also all in their 90s.

Since his Apollo 17 commander, Gene Cernan, died in 2017, Schmidt has been the last man alive to step off the lunar surface.

He also stands out for another reason: Unlike the other Apollo astronauts, who came from the military, Schmitt was a geologist and the only trained scientist to make the historic trip. //

“The question is, will that momentum keep going forward?”

Schmitt says he believes it will through a viable business model for interlunar travel — fueled by an industry involving the reaping of helium-3.

Helium-3 is a key ingredient needed to run nuclear fusion reactors, which operate with extreme efficiency and without the dangerous radioactive waste today’s fission-based power plants create.

But helium-3 is extremely rare on Earth — so rare that it’s rationed by the federal government — meaning fusion reactors have never been viable on a large scale.

But the moon is believed to be ripe with it, since the sun has been bombarding its atmosphere-free surface with the isotope for billions of years and building it up in the grey lunar dust.

“If you want to build a ship, don’t drum up the men to gather wood, divide the work, and give orders. Instead, teach them to yearn for the vast and endless sea.”
― Antoine de Saint-Exupéry

These four are very good at making us yearn for space.

Perhaps because I wasn’t alive during Apollo, part of me has often gravitated to robotic space missions. I identified with spacecraft like Voyager, Cassini, New Horizons, and the rovers traversing Mars as examples of real exploration. It was still possible to connect crewed platforms in low-Earth orbit, like the International Space Station, with the idea of exploring through the attainment of knowledge. With more than 25 years of uninterrupted crewed operations, the ISS has taught NASA and its international partners how to live and work in space and paved the way for the establishment of a permanent base on the Moon.

But it was easy to connect the innate drive to explore with the excitement of seeing new landscapes on Mars, the ghostly plumes of Enceladus, and the heart of Pluto. These were new worlds revealed for the first time, and each discovery sparked a bevy of new questions.

Artemis II struck the same vein, revealing things unseen by human eyes before. Like those missions far out in the Solar System, this was exploration in action. But seeing and hearing what the Artemis II astronauts saw added another dimension. It scratched an itch that a robot can’t reach. Here were human beings, people I’ve met and people you might someday meet, going through an entirely new experience. //

Sure, Artemis II didn’t land on the Moon. That will come on a future Artemis flight. But these four astronauts ventured to greater distances than Apollo and saw parts of the far side of the Moon hidden from view during those missions more than 50 years ago. Modern technology provided new opportunities for the astronauts to share their views with the world—from their view, just a fragile blue marble suspended in a cosmic void.

Speaking from the Orion spacecraft on April 4, Glover, the mission’s pilot, remarked on the view in a long-distance virtual interview with CBS News.

“One of the really important personal perspectives that I have up here is I can really see Earth as one thing,” Glover said on the eve of Easter. “You guys are talking to us because we’re in a spaceship really far from Earth, but you’re on a spaceship called Earth that was created to give us a place to live in the Universe, in the cosmos.

“Maybe the distance we are from you makes you think what we’re doing is special, but we’re the same distance from you, and I’m trying to tell you—just trust me—you are special. In all of this emptiness—this is a whole bunch of nothing, this thing we call the Universe—you have this oasis, this beautiful place that we get to exist together.

“As we go into Easter Sunday, thinking about all the cultures all around the world, whether you celebrate it or not, whether you believe in God or not, this is an opportunity for us to remember where we are, who we are, and that we are the same thing, and that we’ve got to get through this together.” //

“When we saw tiny Earth, people asked our crew what impressions we had, and honestly, what struck me wasn’t necessarily just Earth. It was all the blackness around it. Earth was just this lifeboat hanging undisturbingly in the Universe,” she said. “I know I haven’t learned everything that this journey has yet to teach me, but there is one new thing I know, and that is planet Earth, you are a crew.”

Many people have very strong loyalties to certain brands of oil. They’ll swear by their favorite brand and assure you that anything else is bound to ruin your engine. But we’re here to dispel that myth. After nearly 30 years of testing oils from thousands of different engines and industrial machines, we have discovered a shocking fact: it doesn’t really matter what brand of oil you use.

But wait! Before you dismiss us as heretical, listen to what we do recommend. We always suggest using an oil grade recommended for your engine by the manufacturer and a brand that fits your budget. The grade of oil is much more important to performance in your engine than the brand of oil.

In fact, here’s another little secret. The oils you can find at any mass retailer, such as Wal-Mart or Meijer, are actually name-brand oils (such as Valvoline, Shell, or Quaker State), but with the store’s label on it. Think about it. A place like Auto-Zone is not in the business of manufacturing oil. They buy their oil from the big oil companies and put their name on the bottle. The only difference between the Auto-Zone brand and the name-brand oil is the name on the bottle and a few dollars per quart.

Notice what we have not said we take into account: the brand you’re using and whether it’s synthetic or petroleum oil. When Jim started this company back in 1985 he came up with a line he liked to use: Oil is oil. We still stand by that today. The oil guys would have you believe otherwise, but brand really does not seem to make a difference in how your engine wears, or how often you can change your oil.

Well, okay, if you were using some guy’s oil that he “recycled” in the back of his garage from emptied-out oil pans that he filtered with a piece of cheesecloth, we might say in that case brand does matter. But as long as you’re using an API-certified oil, your engine probably isn’t going to care what you use. We like synthetics and we like conventional oil. In the end, what you use and how often you change your oil is completely your choice. We’ll give you our recommendation and you can do whatever you want with it. If you want to run longer on the oil despite having high wear, that’s totally fine. And if you have great numbers and you like changing at 3,000 miles, that’s perfectly fine too. It’s your engine, your money, and your life: change it when you want!

Students often carry misconceptions about coursework. They may view an instructor as an opponent standing in the way of the grade they want. And they see “getting the right answers” as the goal of education because that’s how you secure that grade.

But that’s no more true than thinking that logging a count of reps is the goal of bodybuilding. The hard work of lifting weights is the point because that yields physical results. A popular analogy is that using an LLM to write your essay is like driving a forklift into the weight room. Weights get lifted, sure, but nothing is accomplished. I’m not hoping you can answer the exam question for me—I don’t need your essay to get me out of a jam. The process of doing the work was what you needed to walk away with something. //

“The friction matters, Sam!”

Green could just as well have been describing the process of learning. If there’s no friction, no effort, then no work occurred, and the student hasn’t learned. They would have been no less productive watching paint dry. //

A question like this is what we call “formative assessment.” I never graded the correctness of the answer, only the effort. The point was to find out if the core concept had really clicked or if that student still needed a little help making the connection. Failure is a useful part of learning when the stakes are low, as they are during the bulk of the class—encountering this question on the final exam would be an entirely different interaction.

What’s the point of building formative assessments into a course if they’re just handed off to an LLM? Suddenly, it’s a waste of time for both the student and the instructor. Small quizzes are excellent study tools to help students check their own understanding―if a student does them. Now, you can direct an “agentic” LLM browser to complete all the quizzes in an entire course with a single, frictionless prompt. //

It doesn’t seem like anyone wants to listen to instructors explain how bad it feels to try to do our job in the presence of this annihilative education antimatter. Instead, we’re offered AI grading tools to score AI-generated submissions for AI-generated assignments.

Perhaps critics like me just don’t understand the AI revolution (whatever that is), but we all have experience with human nature and the well-worn patterns of students. LLMs are a shortcut. Students often take shortcuts they later regret. We’ve all been there.

As an instructor, I want to build a clear path up the mountain for my students and see them reach the top. Instead, I increasingly feel like I’m just playing impossible defense to keep them from moving every direction but up. It’s exhausting, and I will mostly lose, which means I’m not even helping them. Students really do want to climb up there, but it’s always tempting to skip some mountains..

Commander Wiseman, Reid, you said in an interview back in February that you hoped this mission would be forgotten, overshadowed by all that was to come after. But I'm very sorry to disappoint you all. Artemis II will always be remembered. It was the moment we all saw the Moon again. Where childhoold dreams became missions. You helped the world to start believing again, and this is something that no one's ever going to forget. So, on behalf of NASA and the space-loving community from around the world: Thank you, for showing us your courage, your professionalism, your unity, and your humanity. Thank you, for showing us the Moon again. Thank you, for showing us Planet Earth again. And Thank you, for contributing to the greatest adventure in human history. Welcome home, Artemis II. //

So, when we saw tiny Earth, people asked our crew what impressions we had. And honestly, what struck me wasn't necessarily just Earth. It was all the blackness around it. Earth was just this lifeboat hanging, undisturbingly in the universe.

It estimates there are over 100 million consumer routers currently in active use across the US, and the FCC's order impacts the replacement cycle for every one of these devices, as new models cannot be authorized unless they secure Conditional Approval and agree to onshoring requirements.

The existing channel inventory of previously authorized router models will absorb initial demand, but that buffer is finite, and if the Conditional Approval process cannot achieve sufficient throughput within 6 to 12 months, consumers and ISPs will face a constrained selection, the GEA says.

The upshot will be that many will not be able to replace aging and outdated routers, which is more likely to leave them vulnerable to attackers taking advantage of any security flaws in them.

Firms that make router silicon such as Qualcomm, MediaTek, and Broadcom operate on global roadmaps, the report states. If the US certification pathway becomes slower or less predictable than equivalent processes in Europe or Asia, then vendors will prioritize launches in those markets, the report claims. US consumers would see delayed availability of new Wi-Fi 7 models, reduced model selection, or higher prices as companies have to cover compliance costs across fewer units sold.

The commodification of basic app creation has been underway for years. As soon as an app becomes popular, people create clones and offer them for sale through various markets like Flippa, Acquire, AppWill, and CodeCanyon. Or maybe they're selling entire e-commerce sites as turnkey businesses for six figures or more. AI will accelerate that commodification but writing code is only part of the picture.

Claude Code doesn't make you a great marketer or ensure that you're at the right place at the right time with the right idea. It doesn't build trust or develop the relationships that businesses depend on. It doesn't make your RSS app a good idea. But it may open doors you'd otherwise have passed by. ®

Originally, Flyby11 was a simple patcher to remove the restrictions stopping you from installing Windows 11 (24H2) on unsupported hardware.
Old PC? No TPM, no Secure Boot, unsupported CPU? Flyby11 let you install Windows 11 anyway.

After helping thousands upgrade, one thing became clear:
Bypassing checks is only half the battle.
We needed a full setup solution — one that respects user choices instead of Microsoft's defaults.

FlyOOBE was the next step:

Skip the fluff
Remove the junk
Take full control from first boot
Because your PC should work for you, not the other way around.
FlyOOBE keeps the original idea alive and pushes it even further.

Sharing is more dependable if every machine on the network has a credential built in credential manager for each of the other networked machines.

1. Open the Credentials Manager from the Windows Control Panel.
2. Go to Windows Credentials.
3. Click Add a Windows credential.
4. In the "Internet or network address" field, enter \ followed by the computer name or IP address of the computer sharing files or printers.
5. Enter the username and password for an administrator account for the machine you are trying to access. For example I network 4 computers. In each computer I created a credential for the other 3.

Note: Even if computers use the same user account name and password, even the same MS account, you still need to create a credential for it.

It must be a password, not a pin. While you can still use a pin to log in, you must restart the device and log into it using a password at least once for this to work.

Delaware’s business-friendly reputation is why the state has just about one million residents, but two million registered business entities.

That is, until the state's corporate-focused Court of Chancery twice denied Tesla's proposed pay package for Musk, even though it was fully shareholder-approved. The decision was exactly the kind of nanny-statism that companies incorporated in Delaware to avoid.

So Tesla reincorporated in Texas — Wall Street firms have major outposts there now, too, as well as in Florida — and SpaceX quickly followed.

Serving as a corporate P.O. box accounts for as much as one-third of Delaware's state revenues. But clearly that's changing almost as quickly as the Court of Chancery sabotaged the state's reputation in a fit of suicidal pique over Musk's politics. //

What's amazing about Delaware's "bad luck" is just how quickly things began to unravel. It's been more than a century since Delaware became the favorite place for businesses located anywhere to incorporate, thanks to expert Chancery Court judges, predictable corporate legal precedents, and a light regulatory touch. The First State quickly became the legal home for most Fortune 500 companies. No factories. No fancy headquarters. Just a P.O. box. //

Capital finds a way, to misquote Dr. Ian Malcolm.

But as Elon Musk could tell you — and probably did, if you follow him on X — it's a helluva lot easier to move a corporate P.O. box than it is to relocate a billion-dollar HQ.

Delaware forgot that. The exodus has begun.

The Red Army needed pilots, aircraft, and pressure on the enemy—immediately. So they did something profoundly unromantic and brutally practical: they took civilians who could fly and turned them into combat airmen.

Many of the women who became the Night Witches had been flying before the war. Civilian aero clubs were common in the Soviet Union, and flight was encouraged as a national skill. These weren’t cosplayers handed wings for morale photos. They were trained aviators, suddenly handed bombs instead of mailbags. Under the leadership of Marina Raskova, they were organized, uniformed, and sent to the front.

Their aircraft was the Polikarpov Po-2, which deserves special mention because it may be the least intimidating combat aircraft ever to terrify a modern army. Built of wood and fabric, slow enough to be outrun by some farm equipment, and equipped with little more than a compass and stubbornness, the Po-2 was not supposed to survive combat. That turned out to be its greatest strength.

The mission assigned to the regiment was night harassment bombing. This was not about destruction; it was about erosion. The goal was to deny German forces something every soldier needs more than ammunition: sleep. Night after night, the Po-2s would appear over German positions, often flying just above treetop level. At the last moment, the pilots would cut their engines and glide silently, releasing small bombs before disappearing back into the darkness.

That silence mattered. //

Psychologically, this was devastating. Armies can endure danger. They struggle against uncertainty. The Night Witches turned the night itself into an enemy. They forced the Germans to spend time, fuel, ammunition, and attention on an aircraft that cost almost nothing to operate. A single crew might fly multiple sorties in a single night, returning to refuel and rearm in primitive fields, then heading back out again.

The numbers tell the story. By the end of the war, the regiment had flown roughly 23,000 sorties. That is not a stunt. That is persistence weaponized. Each individual mission might have been minor, but together they created a constant, grinding pressure on German rear areas. Officers complained. Troops cursed. Morale eroded. The nickname “Night Witches” was not admiration—it was fear mixed with exhaustion.

This is the part modern audiences often miss. The Night Witches were not trying to win battles in the cinematic sense. They were trying to make the enemy miserable, distracted, and tired at scale. It was warfare by irritation, perfected through repetition. And it worked precisely because it was unconventional.

Desperate times reward asymmetric thinking. The Soviets didn’t wait to build perfect aircraft or ideal forces. They repurposed what existed. Civilian pilots became military crews. Trainers became bombers. Night became a weapon. The Night Witches are a textbook example of how nations under existential threat blur the line between civilian and soldier—not out of ideology, but necessity.

Multicarrier prepaid service US Mobile said it is offering bundles for new and existing customers, including residential Starlink, for as low as $47 per month. Essentially, the cheapest plan combines US Mobile’s base unlimited plan at $17 per month with Starlink's residential plan at $30 per month, which offers 100 Mbps download speeds. //

What makes US Mobile unique in the marketplace is that it can offer customers the ability to choose the network they want to use, which they call Dark Star (AT&T), Warp (Verizon), and Light Speed (T-Mobile).
