The Barrett SSRS is a recoil-operated, magazine-fed, semi-automatic rifle chambered in 30×42 mm

Wednesday, September 17th, 2025

During DSEI UK 2025 in London, Barrett Firearms introduced its 30mm Squad Support Rifle System (SSRS). developed in cooperation with Mars Inc., to the public outside the US:

The weapon recently won the U.S. Army’s xTech Soldier Lethality Competition and secured USD 2 million in funding, confirming its relevance in the ongoing Precision Grenadier System (PGS) program.

[…]

The Barrett SSRS is a recoil-operated, magazine-fed, semi-automatic rifle chambered in 30×42 mm. The system is compact and ergonomic, with an overall length of 861 mm and a 305 mm barrel, while its weight remains approximately 6.3 kg with the integrated fire control system. Feeding from five-round detachable magazines, the SSRS provides dismounted units with the ability to engage targets up to 500 meters in less than three seconds, offering a much flatter trajectory than traditional 40×46 mm low-velocity grenades. With an effective range greater than most current squad-level grenade launchers, it enhances both precision and lethality in medium-range engagements.

A distinctive feature of the system is its advanced Direct Fire Control – Precision Targeting (DFC-PT) unit, developed by Precision Targeting LLC. This electro-optical fire control system integrates a laser rangefinder, ballistic solver, environmental sensors, and a disturbed reticle, significantly improving first-round hit probability. The SSRS is also designed for compatibility with remote weapon stations, expanding its application beyond individual infantry use to vehicle-mounted platforms.

Development has been rapid. Within eleven months, Barrett and Mars Inc. designed, built, and tested the SSRS, demonstrating its effectiveness under the U.S. Army’s Precision Grenadier System requirement. This achievement led to its recognition as the winner of the Army’s Soldier Lethality Competition in May 2025. Ammunition developed by Amtec Corp. further broadens its operational spectrum, with multiple natures including High Explosive Dual Purpose (HEDP), Close Quarters Battle (CQB), anti-drone rounds, and training practice slugs. This variety makes the weapon adaptable to both urban combat and counter-drone operations, two of the most pressing challenges on today’s battlefields.

We’ve discussed the SSRS before.

Every physical element of Edison’s 1877 tinfoil phonograph was within reach

Monday, September 15th, 2025

What’s the earliest someone could have made a phonograph if they’d understood the basic principles involved? Quite early, ChatGPT says:

A screw-cutting lathe drawn in 1483 shows that late-medieval instrument makers already had a leadscrew, treadle/hand-crank drive, and slide rest accurate enough to carry a stylus slowly along a rotating cylinder.

With beeswax — ubiquitous and soft enough to take fine impressions — and thin metal or animal-skin diaphragms coupled to a simple horn, every physical element of Edison’s 1877 tinfoil phonograph was within reach; nothing required steam power, electricity, or metallurgical advances later than the 15th century. Wax itself was later used in commercial cylinders.

So, had someone grasped the “vibrate-stylus-in-groove” idea, a crude yet understandable recorder-player could have been built in Western Europe around the end of the 15th century — almost four centuries before Edison.

The company is able to produce each episode for $1 or less

Saturday, September 13th, 2025

Inception Point AI is attempting to build a stable of AI talent to host podcasts :

“We believe that in the near future half the people on the planet will be AI, and we are the company that’s bringing those people to life,” said CEO Jeanine Wright, who was previously chief operating officer of podcasting company Wondery, which has recently had to reorganize under the changing podcast landscape.

The company is able to produce each episode for $1 or less, depending on length and complexity, and attach programmatic advertising to it. This generally means that if about 20 people listen to that episode, the company made a profit on that episode, without factoring in overhead.

Inception Point AI already has more than 5,000 shows across its Quiet Please Podcast Network and produces more than 3,000 episodes a week. Collectively, the network has seen 10 million downloads since September 2023. It takes about an hour to create an episode, from coming up with the idea to getting it out in the world.

The company produces different levels of podcasts. The lowest level involves weather reports for various geographic areas or simple biographies and higher levels involving subject-area podcasts hosted by one of about 50 AI personalities they’ve created, including food expert Claire Delish, gardener and nature expert Nigel Thistledown and Oly Bennet, who covers off-beat sports.

As for how it stacks up against human podcasts? “I think that people who are still referring to all AI-generated content as AI slop are probably lazy luddites. Because there’s a lot of really good stuff out there,” Wright said.

[…]

The idea behind the company came after Corbin accidentally developed a hit podcast during the pandemic in which he read daily CDC reports, and then branched out into weather reports and other shows that took off, including A Moment of Silence (an actual minute of silence). At the time, they were not using AI.

80,000 cameras pointed at highways and parking lots

Saturday, September 6th, 2025

Since its founding in 2017, Flock, which was valued at $7.5 billion in its most recent funding round, has quietly built a network of more than 80,000 cameras pointed at highways and parking lots across the U.S.:

Growth has been explosive, with revenue up some 70% from the estimated $175 million it booked in 2023. It’s not yet profitable and has no imminent plan to be as it prioritizes growth, backed by a $275 million March funding round led by Andreessen Horowitz. Those numbers were more than sufficient to land Flock on Forbes’ 2025 Cloud 100 list of the top private cloud computing companies. Langley says turning Flock into a $100 billion business is “very within reach.” Ilya Sukhar, an early investor and partner at VC firm Matrix who sits on Flock’s board, agrees. “It’s a bit cliché, but it does feel like we’re just getting started,” he says. “It’s not hard for me to project to a place where we get to that level.”

Each Flock license plate reader cam costs between $3,000 and $3,500, with an additional fee for FlockOS, the operating system that makes all the data Flock collects accessible via a browser or a mobile app, based on either the number of users or cameras. Dunwoody PD, for instance, pays around $500,000 annually for its array of 105 cameras, gunshot detectors, that skittering DJI drone and the software that controls it all.

Flock’s growth isn’t solely fueled by its 5,000 law enforcement customers across 49 states (it hasn’t yet installed its cameras in Alaska). It has 1,000 corporate customers, including blue chips like FedEx, Lowe’s and Simon Property, America’s largest mall owner. Then there are housing and homeowner associations, small businesses, schools and organizations like the Jewish Federation of Greater Atlanta, which has installed 64 Flock cameras across different properties in the city, including a community center that has reported a recent spike in antisemitic threats to Dunwoody police. All these customers can choose to grant the police access to their camera feeds, further expanding the surveillance coverage Flock can offer law enforcement. Many do.

Langley had no experience in police tech when he and fellow Georgia Tech alums Matt Feury, 36, and Paige Todd, 40, started the company in 2017. Previously they’d worked together on an app Langley cofounded for upgrading sports or concert seats to VIP-status events, where Feury and Todd were early employees. (It was acquired by Atlanta-based conglomerate Cox Enterprises and no longer exists.) Inspired by an unsolved robbery in Langley’s neighborhood, the trio started work on the first Flock prototype, an Android phone camera in a waterproof box that took pictures of cars and picked out license plates that could then be searched via an app.

The modern battlefield requires split-second decision-making, seamless coordination among distributed teams, and processing vast amounts of information, all under extreme pressure

Thursday, September 4th, 2025

The modern battlefield requires split-second decision-making, seamless coordination among distributed teams, and processing vast amounts of information, all under extreme pressure:

As I have learned over the last year, as an advisor to August Interactive, a gaming studio, these are exactly the skills that well-designed military gaming programs can develop and refine.

Unlike traditional military wargaming — which typically involves structured, turn-based exercises on maps or models to explore campaign plans and strategic concepts — the gaming discussed here draws heavily on digital interactive platforms, including modified commercial titles and purpose-built military simulations. These environments — ranging from real-time strategy games to tactical shooters, flight simulators, and cyber-themed games — emphasize rapid continuous decision-making, high-pressure coordination, and immersive skill development. While both approaches aim to sharpen judgment and prepare leaders for complex scenarios, this form of military gaming leverages the speed, interactivity, and scale of modern gaming technology to cultivate competencies that are difficult to replicate in traditional wargaming formats. And they are also more engaging and fun, which is a good thing.

The U.S. military should formally embrace and invest in advanced digital gaming as a core training tool, leveraging its ability to build critical cognitive, coordination, and technical skills for modern warfare.

[…]

I visited the gaming center at West Point last spring. I was impressed with the setup and technological capabilities, but I was even more impressed by the insights shared with me by combat-experienced officers and non-commissioned officers overseeing the program. The positive impact on cadet leadership development was remarkable: improved communication skills, quicker decision-making, and faster adaptability to change. Notably, many intercollegiate athletes there are involved in military gaming.

Latest driver death rates highlight dangers of muscle cars

Monday, September 1st, 2025

The Insurance Institute for Highway Safety has been calculating driver death rates approximately every three years since 1989, and also calculated the best and worst models according to the number of drivers in other vehicles killed in crashes with them on its last study:

Six of the 21 vehicles with the highest driver death rates for model year 2020 are variants of the Chevrolet Camaro, Dodge Challenger, Dodge Charger and Ford Mustang, while eight others are small cars or minicars. Eighteen of the 23 vehicles with the lowest driver death rates are minivans or SUVs, and 12 are luxury vehicles.

“We typically find that smaller vehicles have high driver death rates because they don’t provide as much protection, especially in crashes with larger, heavier SUVs and pickups,” said IIHS President David Harkey. “The muscle cars on this list highlight that a vehicle’s image and how it is marketed can also contribute to crash risk.”

That might not be how I’d phrase it.

But three Dodge muscle cars with excessively high driver death rates also rank among the worst performers when it comes to other-driver deaths, suggesting these vehicles are driven in an aggressive manner.

Seven of the 20 vehicles with the highest other-driver death rates are large or very large pickups, and four more are midsize SUVs — categories that aren’t represented among the models with the worst track record for protecting their own drivers. Seven of the vehicles with the highest other-driver death rates also rank among the worst for driver death rates: the Dodge Challenger two-wheel-drive, Dodge Charger two-wheel-drive, Dodge Charger HEMI two-wheel-drive, Kia Forte, Kia Optima, Kia Rio sedan and Nissan Altima.

The list of vehicles with the lowest other-driver death rates include two small, two midsize and one large car, as well as six small and 10 midsize SUVs. Ten models are luxury vehicles.

The rates include only driver deaths because all vehicles on the road have drivers, but not all of them have passengers or the same number of passengers. The number of deaths is derived from the federal Fatality Analysis Reporting System. Registration data come from IHS Markit.

The latest rates are based on fatalities that occurred from 2018 to 2021 for vehicles from the 2020 model year, as well as earlier models with the same designs and features. The numbers represent the estimated risks for 2020 models, but the data include models from as far back as 2017 if the vehicles have not been substantially redesigned over the intervening period. Including these older, equivalent vehicles makes the sample size larger and therefore increases the reliability of the results. To be included, a vehicle must have had at least 100,000 registered vehicle years of exposure from 2018 to 2021 or at least 20 deaths.

[…]

The lists of vehicles with the lowest driver and other-driver death rates have nine models in common. These include the Acura MDX four-wheel-drive, Audi Q5 four-wheel-drive, Chevrolet Traverse four-wheel-drive, Lexus RX 350 four-wheel-drive, Mercedes-Benz E-Class sedan four-wheel-drive, Porsche Macan, Subaru Ascent, Toyota C-HR and Volvo XC60 four-wheel-drive. Notably, six of those are luxury vehicles.

“The models that rank among the best and worst performers on both lists point to the unfortunate fact that vehicle cost remains a factor in road safety,” Harkey said.

Vehicle cost — or driver income?

Minicars had the highest driver death rates, averaging 153 deaths per million registered vehicle years. Very large luxury cars had the lowest, averaging only 4 deaths. In contrast, very large pickups had the highest other-driver death rates, averaging 121 deaths, while small sports cars had the fewest other-driver deaths, averaging only 11 per million registered vehicle years.

The average other-driver death rate for all 2020 and equivalent models was 53 deaths per million registered vehicle years. There are more other-driver fatalities than driver fatalities because these newer models are more crashworthy than many of their crash counterparts, which come from the wider U.S. fleet, made up of mostly older vehicles.

These “farmer tools” greatly simplified Ford’s machining operations

Sunday, August 31st, 2025

Origins of Efficiency by Brian PotterFord’s status as a large-volume car producer began with the predecessor to the Model T, Brian Potter notes, the Model N, a four-cylinder, two-seater car initially priced at $500:

Many of the Model N’s parts were made of vanadium steel, a strong, lightweight, durable steel alloy. Vanadium steel allowed for a lighter car (the Model N weighed only 1,050 pounds), and was “machined readily.” This was important because Ford also made increasing use of advanced machine tools that allowed it to produce highly accurate interchangeable parts. In 1906, Ford advertised that it was “making 40,000 cylinders, 10,000 engines, 40,000 wheels, 20,000 axles, 10,000 bodies, 10,000 of every part that goes into the car…all exactly alike.” Only by producing interchangeable parts, Ford determined, could the company achieve high production volumes and low prices. Furthermore, Ford’s machine tools were arranged in order of assembly operations rather than by type, allowing parts to move from machine to machine with minimal handling and travel distance. It also made extensive use of production aids such as jigs, fixtures, and templates. These “farmer tools” — so called because they supposedly made it possible for unskilled farmers to do machining work — greatly simplified Ford’s machining operations.

The Model N was so popular that demand exceeded capacity, which allowed Ford to plan production far in advance. This meant Ford could purchase parts and materials in large quantities at better prices and schedule regular deliveries, ensuring a steady, reliable delivery of material, which allowed it to maintain just a 10-day supply of parts on hand.

To build your own drone batteries, you have to source quality cells from a reliable supplier and assemble them into battery packs

Saturday, August 30th, 2025

If you break open a drone battery, David Hambling notes, you will find a shrink-wrapped block containing smaller batteries:

These cells are described by their size, so an 18650 cell is a cylindrical unit about 18 millimeters in diameter and 65 millimeters in height, while a 2170 is 21mm in diameter and 70 mm high.

A typical laptop battery will contain six 18650 lithium-ion cells. The battery pack for a Tesla Model 3 Long Range made before 2018 contains 2170-type cells, no less than 4,416 of them.

While not all cells are created equal, they are essentially commodity products manufactured by the billion. They’re made mainly by big players in the Far East; China dominates but it does not have a monopoly. Other sources are readily available.

The biggest battery maker by capacity is Chinese outfit CATL, making 132 GWH of cells every year. But the next two are South Korean LG (93 GWH) and Japanese Panasonic (60 GWH), and there are two other Korean outfits, Samsung and SK, in the top ten.

To build your own drone batteries, you have to source quality cells from a reliable supplier and assemble them into battery packs. And that is exactly what Ukrainian drone maker Wild Hornets has been doing for some time.

A video on social media explains Wild Hornets’ process. The building blocks for its battery packs are Samsung 50S, which are optimized for high-power applications and have a respectable 5000 mAH capacity.

The cells are arranged in blocks of 12 in a 6s2p unit (that is, 6 rows of 2 batteries) or 18 in 6s3p (6 rows of 3) configuration. These are connected with metal strips and 0.25 mm copper wiring — “we don’t economize” the presenter says in the video — spot welded into place. Spot welding is costlier than soldering, but more reliable. The completed unit is then securely shrink-wrapped with multiple layers of tough plastic.

[…]

The end result costs a total of $65 for small batteries and $90 for large, similar to commercial drone batteries.

Of course, they’re called batteries because they’re collections of smaller cells:

Benjamin Franklin first used the term “battery” in 1749 when he was doing experiments with electricity using a set of linked Leyden jar capacitors. Franklin grouped a number of the jars into what he described as a “battery”, using the military term for weapons functioning together.

Skilled immigrants often constitute an espionage risk

Wednesday, August 13th, 2025

Given the reality of mixed loyalties, Arctotherium notes, it shouldn’t be surprising that skilled immigrants often constitute an espionage risk:

Take the infamous Pakistani nuclear physicist AQ Khan. In 1961, he moved to West Berlin as a foreign student, then to the Netherlands and finally Belgium to finish his education, graduating with a Doctorate in Engineering in 1972. Khan was undoubtedly among the best and brightest of Pakistan, the sort of high-agency STEM genius that brain drain advocates hold up as America’s greatest strength. Was allowing A.Q. Khan into the West a good decision? No.

Khan got a position at the Physics Dynamics Research Laboratory, a Dutch firm specializing in uranium enrichment via centrifuge. He stole centrifuge designs and blueprints, and after returning to Pakistan set up an international network of illicit suppliers for centrifuge parts using his contacts, leading to the 1998 Pakistani nuclear bomb. From there, he diffused nuclear technology further. The North Korean, Iranian and Libyan nuclear programs all trace back to A.Q. Khan. Pakistan has had multiple serious nuclear war scares with India in the last five years. North Korea, which has a history of doing things like axe-murder Americans, can act with relative impunity thanks to its nuclear arsenal, and Israel and the US recently bombed Iran over their nuclear program.

There are many examples from the US. For instance, Noshir Gowadia, an Indian Parsi designer of the B-2 Spirit stealth bomber, and Chi Mak, who worked on nuclear submarines, both sold secrets to China.

Groves was too aggressive and might have difficulty with the scientific people

Saturday, August 9th, 2025

Now It Can Be Told by Leslie M. GrovesVannevar Bush headed the U.S. Office of Scientific Research and Development (OSRD) during World War 2, and General Groves admits that Dr. Bush was quite disturbed at Groves’ appointment as head of the Manhattan Project, as he explains in Now It Can Be Told: The Story of the Manhattan Project, because he felt Groves was too aggressive and might have difficulty with the scientific people. After their first inauspicious meeting, Groves went back to his office:

Finding my secretary, Mrs. O’Leary, there, I told her I was being reassigned and that if she wanted to come along, I would be glad to have her. I added, in what proved to be a great understatement, that this would be a very quiet and easy job for her and she should be sure to bring along some knitting to keep herself occupied. This prediction proved valid for about two days.

When I returned home that evening I told my wife and daughter and wrote to my son, a cadet at West Point, that I had a new job, that it involved secret matters and for that reason was never to be mentioned. The answer to be given if they were asked what I was doing was, “I don’t know, I never know what he’s doing.” To my son, I added, “If it is an officer who knows me well, and he is persistent, you can add, ‘I think it’s something secret.’”

[…]

Unlikely as it may seem to many people, they first learned of the nature of my assignment at the same moment, three years later, that the bombing of Hiroshima was announced to the rest of the world.

It was much less than our total over-all spending in a normal week

Saturday, August 2nd, 2025

Now It Can Be Told by Leslie M. GrovesIn September, 1942, Leslie Groves was serving as Deputy Chief of Construction of the Army Corps of Engineers, overseeing all Army construction, at home and abroad, but he wanted to get in on the real action. Instead, as he explains in Now It Can Be Told: The Story of the Manhattan Project, he was offered a role in Washington:

“I don’t want to stay in Washington.”

“If you do the job right,” Somervell said, “it will win the war.”

My spirits fell as I realized what he had in mind. “Oh, that thing,” I said.

[…]

Though a big project, it was not expected to involve as much as $100 million altogether. While this was more than the cost of almost any single job under my jurisdiction, it was much less than our total over-all spending in a normal week.

[…]

“The basic research and development are done. You just have to take the rough designs, put them into final shape, build some plants and organize an operating force and your job will be finished and the war will be over.”

[…]

In the course of our discussion, we agreed that, because the Pentagon was so nearly finished and because I had had so much to do with it, I would continue to control its construction, despite my new assignment. There were two reasons for this. First, my sudden disappearance from the work on the Pentagon would attract much more notice than would my absence from my other Army construction activities. Second, because of the natural interest in the Pentagon displayed by a number of Congressmen, it would be better for me to continue to carry the responsibility for that job than to pass it on to someone else who was unfamiliar with its past problems and their many political ramifications.

[…]

I thought that there might be some problems in dealing with the many academic scientists involved in the project, and I felt that my position would be stronger if they thought of me from the first as a general instead of as a promoted colonel. My later experiences convinced me that this was a wise move; strangely enough, it often seemed to me that the prerogatives of rank were more important in the academic world than they are among soldiers.

At the time I was brought into the picture, research on the uses of atomic energy had been going on at a gradually accelerating pace since January, 1939, when Lise Meitner explained that the uranium atom could be split.

[…]

Virtually all laboratory research until this time had been aimed at achieving a controlled chain reaction, using U-235, a rare isotope of uranium which comprises less than one percent of the metal in its natural state. This isotope has the property of fissioning readily—a property which the far more abundant form of uranium, U-238, does not display. But it soon became apparent that unless unprecedented quantities of this material could be produced in a much purer state, a U-235 chain reaction would be impossible. The basic problem was to arrive at an industrial process that would produce kilograms of a substance that had never been isolated before in greater than sub-microscopic quantities.

[…]

The way for a major breakthrough was open as a result of studies that suggested the theoretical feasibility of transmuting U-238 into a highly fissionable new element, plutonium, which might then be separated from the parent uranium by chemical means. The hope was that this would be easier to do than to isolate or concentrate the rare U-235 by physical means. The group headed by Dr. Glenn T. Seaborg at the University of California undertook to prepare extremely small amounts of plutonium, and in March of 1941 succeeded in creating the first submicroscopic amounts of Plutonium-239. Later that month the California group confirmed the theory that under neutron bombardment plutonium atoms fissioned as readily as atoms of U-235.

[…]

The entry of the United States into World War II caused the abandonment of all projects aimed at developing atomic energy as a source of power and gave added impetus to the efforts to build an atomic bomb.

[…]

It is to their everlasting credit that Bush and his colleagues had the discernment to recognize the limitations of their own organization as well as the moral fortitude to admit them in the national interest. Very few men, confronted with a similar situation, would have done so.

Consequently, when the Top Policy Group met on December 16, 1941, Bush recommended that the Army Corps of Engineers carry out the construction work, and asked that a competent Army officer become thoroughly familiar with the project.

[…]

When the Corps of Engineers started its work, its job was simply to build and operate the production plants. The problems involved in the development of the bomb and its delivery were for the time being largely ignored.

Nor was the full magnitude of the project generally appreciated. No one thought of it as entailing expenditures running into the billions of dollars.

His own advice about self-reliance was actually worth taking in his own case

Tuesday, July 22nd, 2025

Diamond Age by Neal StephensonThe most relevant aspect of Neal Stephenson‘s work to an audience of AI researchers was the Young Lady’s Illustrated Primer from his 30-year-old novel The Diamond Age:

At the beginning of this book we see a conversation between Lord Finkle-McGraw, who is an Equity Lord in a futuristic neo-Victorian society, and John Hackworth, an engineer who works in one of his companies.

Finkle-McGraw is a classic founder. He didn’t come from a privileged background, except insofar as having a stable family and a decent basic education confers privilege. But when he was young he was brilliant, ambitious, hard-working, and had a vision. He built that into something valuable and as a result became rich and powerful. As so often happens, he used his money to make life good for his children by sending them to the right schools, connecting them to the right people, and so on.

He wasn’t entirely happy with the results. His kids didn’t end up having the traits that had made him successful. He suspects it’s because they didn’t have to work hard and overcome obstacles. Now he has a granddaughter. He knows that the parents are going to raise this girl in the same way, with the same results. He can’t interfere in a heavy-handed way. But the parents can’t possibly object if he gives his granddaughter an educational book. So he commissions Hackworth to make the Young Lady’s Illustrated Primer, an interactive book that will adapt as the user grows and learns. This book is powered by molecular nanotechnology, but any present-day reader will immediately recognize it as an AI system.

As the plot unfolds, three copies of the Primer are made and bestowed on girls from very different backgrounds. In two cases the result is a sort of fizzle. The Primer works as it’s supposed to for a while, but these girls lose interest and set it aside. The third copy falls into the hands of a girl from an abusive and underprivileged background, and it ends up giving her close to superhuman abilities.

Thirty years on, I think I have enough distance on this to grade my performance. I’m happy with the fact that the Primer, as described in the novel, doesn’t invariably produce great results. That seems like a measured and realistic outcome. Nevertheless it’s clear that when I wrote this thing I was influenced by a strain of techno-utopian thinking that was widespread in the mid-1990s, when the Internet was first becoming available to a mass audience. In those days, a lot of people, myself included, assumed that making all the world’s knowledge available to everyone would unlock vast stores of pent-up human potential.

That promise actually did come true to some degree. It’s unquestionably the case that anyone with an Internet connection can now learn things that they could not have had access to before. But as we now know, many people would rather watch TikTok videos eight hours a day.

[…]

The gist of it is that the system we’ve traditionally used for evaluating students’ performance — homework and tests — just happens to be exquisitely vulnerable to being hacked by students who simply use conversational AI systems to do all the work for them. And they are doing so on a massive scale, to the point where conventional education has essentially stopped functioning. The only way to fairly evaluate how much a student has learned now is by marching them into a classroom with no electronics, handing them a pencil and a blank blue book, and assigning them an essay to write or a math problem to solve. Even this is impractical given that many students never really learned to write by hand.

[…]

This question sent me down a rabbit hole on the topic of self-reliance. After all, if AI-driven education does nothing more than make students even more reliant on AI, then it’s not education at all. It’s just a vocational education program teaching them how to be of service to AIs. The euphemism for this role is “prompt engineer” which seems to be a way of suggesting that people who feed inputs to AIs are achieving something that should be valorized to the same degree as designing airplanes and building bridges.

If such a system actually did its job it would have the paradoxical effect of making students less, rather than more, reliant on the use of AI technology.

[…]

My thought last week was that Self-Reliance might contain some wisdom applicable to the challenge of how to educate people in the modern world to rely upon their own knowledge and skill set rather than using AI all the time.

Reader, I did not find anything like that upon re-reading this essay. More the opposite. The overall drift of what Emerson is saying here — and he says it over and over — is that each mind is uniquely positioned to see certain insights. The self-reliant person shouldn’t ignore those merely because they don’t match the conventional wisdom. “The eye was placed where one ray should fall, that it might testify of that particular ray…God will not have his work made manifest by cowards….He who would gather immortal palms (i.e. be honored for great achievements) must not be hindered by the name of goodness, but must explore if it be goodness. Nothing is at last sacred but the integrity of your own mind.”

That is all intoxicating stuff for a smart young man who styles himself as a free thinker and nonconformist, which is why, when I was in my early twenties, I inhaled it like fentanyl fumes off hot foil. But during the same years as I was poring over this essay and jotting down quotes in my notebook, I was writing by far the worst novel I have ever written—a book that has never been published and never should be.

Emerson grew up in Boston, attended Boston Latin and Harvard, then traveled around Europe and visited England where he hung out with Wordsworth, Coleridge, and Thomas Carlyle. His brain was preloaded with the best knowledge base that could possibly have been given a young person of that era. He’d been trained to think systematically and rigorously and to express himself with great fluency in English and probably Latin and other languages as well.

So, yes, when an idea popped into Emerson’s head, chances are it was a pretty damned good one. His own advice about self-reliance was actually worth taking in his own case. And I’d guess that the audience for this essay was similarly well educated. By the time any young person happened upon Self-Reliance, they were probably 99% of the way to being an intellectually mature, highly capable person, and just wanted a bit of self confidence to follow through on good ideas that were coming into their heads—as a result of being that well educated and trained.

When the same advice falls on the ears of people who are not as well informed and not as good at thinking systematically, though, it’s rubbish.

When I first read Self-Reliance, only a few years had passed since the premier of the first Star Wars movie. There’s a pivotal moment in that film when Luke Skywalker is piloting his fighter through the trench on the Death Star, making his bombing run against impossible odds, and he hears Obi-Wan Kenobi’s voice in his head telling him to use the Force. Luke switches off his targeting computer to the consternation of the brass in the ops center. We all know the outcome. It’s a great moment in cinema, and it perfectly encapsulates a certain way of thinking emblematic of the 1970s late hippie scene: the seductive proposition that no one needs a targeting computer, that all we need to do is trust our feelings. Who doesn’t love to hear that? I loved hearing it from Ralph Waldo Emerson, and spent a couple of years of my life building a terrible novel on that foundation.

I have discussed The Diamond Age before.

A 2- or 3-year machinist or mechanic apprenticeship was mandatory for admission to any German engineering academy

Herman the German by Gerhard NeumannDavid Foster reviewed Gerhard Neumann‘s Herman the German ages ago, but I was recently reminded of it:

This is the autobiography of a man who was born to a Jewish family in Germany, apprenticed as an auto mechanic, attended engineering school, moved to China in 1938, was interned by the British as an enemy alien in 1939, transferred to the American forces, joined Claire Chennault’s Flying Tigers, repaired the first Japanese Zero fighter to be captured in potentially flyable condition, became a U.S. citizen by special act of Congress, and went on to run GE’s entire jet engine business, which he played a major role in creating. (The preceding may be the longest single sentence I’ve ever written in a blog post.) The book should be of interest to those interested in aviation, technology, management, social history, the WWII era, and/or China.

Gerhard Neumann was born in Frankfurt/Oder in 1917, where his father was owner of a factory that processed feathers and down. Gerhard’s parents were Jewish but nonpracticing–a Christmas tree was traditional in the Neumann home–and their approach to child-raising was closer to stereotypically Prussian than to stereotypically Jewish: “You did exactly as you were told by your parents. There was no such thing as saying no to them!…You were not to have a hand in your pocket while talking to grown-ups…Showing any emotion in Prussia was considered sissyish. There was no kissing between parents and children–only a peck on the cheek before going upstairs punctually at nine o’clock; and there was absolutely no crying.”

On the other hand, Neumann could do pretty much what he wanted with his spare time. In 1927, at the age of 10, he rode his bike out to a grass strip where someone was giving airplane rides for 5 marks, which he paid with money from his piggy bank. His parents weren’t angry at him for taking this flight without permission; indeed, they were so entranced with his description of the way the town looked from the air that they soon took an airplane ride themselves! At the age of 13, Neumann bought a folding kayak and, with some camping gear and a 12-year-old friend, took long journeys on the Oder River, all the way to the Baltic Sea. Few parents in America today–or in Germany either, I’d bet–would now allow this level of independence to a 12- or 13-year old.

Neumann had no interest in the family feather business; he wanted to be an engineer. A 2- or 3-year machinist or mechanic apprenticeship was mandatory for admission to any German engineering academy: Neumann’s father asked the 10 cab drivers of Frankfurt/Oder to recommend the garage where they thought the boy would learn the most, and the answers were unanimous: Albert Schroth’s. So began Gerhard Neumann’s apprenticeship, which, other than the technologies involved, could have been something out of the Middle Ages. “In winter my hands were frozen purple. Wear work gloves? ‘What’s the matter, boy, are you a girl?’ When my hands were bleeding, Herr Schroth pointed to the large bottle of iodine in the backroom and mumbled something about faules Fleisch (lazy flesh.) No Band-Aids, no pitying, no time out.”

At first, Neumann had second thoughts about the path he had chosen. “My friends were still continuing at the Gymnasium, spending their days in comfortable and clean surroundings; here I was, accustomed to a fine home and the luxury of two maids and a chauffeur, becoming a grease monkey for three long years.” But Neumann found the work interesting, and took pride in the high reputation of the shop.

At the conclusion of the three-year apprenticeship, Herr Schroth said “Thank you, Neumann”…the only time that he had ever said “thank you” to his apprentice, or called him anything other than “boy”…and sent a bouquet of flowers to Neumann’s mother. “I felt sincerely grateful when I, in turn, thanked Herr Schroth–the man whom I had always addressed as Meister and who had given me a solid groundwork for what I hoped would be a rewarding engineering future.”

Neumann says that up to the time he left Frankfurt to attend engineering college in the mid-1930s, he encountered no open anti-Semitism at all. Even at the Mittweide engineering college, where he was one of three Jewish students (each of their fathers had been soldiers in the First World War, which made them eligible for a college education), he says that he was never insulted by Nazi fellow students. Even allowing for the fact that attitudes toward Jews did differ considerably in different parts of Germany, these statements are hard to believe given that the Hitler regime had been in place since 1933.

About 15% of the Mittweide students were foreign, and they were exempt from the requirement, binding on German students, to have previously undergone an apprenticeship. “Because they had never dirtied their hands or bloodied their knuckles in apprentice-type training, they did not benefit from the Mittweida-type education anywhere as much as did a German student.” The Mittweida approach to engineering education included drawings in which errors had been deliberately inserted–“We were taught to ‘get a feel’ for drawings laid before us. The question constantly posed was, Would it really do the job if it were built just as shown on this drawing?”

Engineering students were exempt from the draft while in school, but not after graduation. A few weeks before the end of 1938, Neumann noticed an item on the college bulletin board: the Chinese government was looking for German mechanical engineers. And the Chinese Nationalist government had arranged with the German Nazi government that these engineers would have their German military service requirement deferred.

“The notice was vague about the jobs, which apparently were somewhere in the interior of the Chinese mainland and were connected with defense. A job in faraway China sounded incredibly exciting…”

Incredibly exciting it turned out to be, and most of the book is concerned with Neumann’s remarkable adventures in China. It was also, surely, lifesaving–had Neumann remained in Germany, it is most unlikely he would have survived the Holocaust.

He very often managed to ignore complexity

Saturday, July 19th, 2025

Now It Can Be Told by Leslie M. GrovesIn the introduction to Leslie Groves’ Now It Can Be Told: The Story of the Manhattan Project, Edward Teller paints a picture of the general:

The readers of General Groves’s own account are to be complimented for choosing to learn directly from one of the major participants. History in some ways resembles the relativity principle in science. What is observed depends on the observer. Only when the perspective of the observer is known can proper corrections be made.

[…]

Vannevar Bush, the head of all scientific wartime projects, interviewed General Groves prior to his appointment to the Los Alamos project. Bush suggested to the office of the Secretary of State that Groves might lack sufficient tact for such a sensitive role.

[…]

He very often managed to ignore complexity and arrive at a result which, if not ideal, at least worked.

[…]

He had to worry both about the diffusion of uranium hexafluoride molecules and about the problems faced by the wives in Los Alamos. (As Groves mentions, contrary to local gossip, Los Alamos was not an establishment for the care of pregnant WACs).

[…]

For Groves, the Manhattan Project seemed a minor assignment, less significant than the construction of the Pentagon.

[…]

He started with, and partially retained, thorough doubts about the feasibility of the project. Yet in convincing the leaders at DuPont that they should participate, he appeared totally confident in order to overcome the incredulity of those overly sane chemical engineers.

[…]

I know of no one whose work begins to compare in excellence with that of Oppenheimer’s.

Oppie knew in detail the research going on in every part of the laboratory, and was as excellent at analyzing human problems as the countless technical ones. Of the more than 10,000 people who eventually came to work at Los Alamos, Oppie knew several hundred intimately, by which I mean that he understood their relationships with one another, and what made them tick. He knew how to lead without seeming to do so. His charismatic dedication had a profound effect on the successful and rapid completion of the atomic bomb.

[…]

One of my jobs at Los Alamos was to assure the safety conditions in the gas diffusion plant. The main hazard was that in advanced stages of separating U235 and U238, contamination with water or some other substance might cause the diffusing gases to solidify, at which point an unwanted chain reaction might result. This part of my job took me from time to time to New York, and one morning (at 4:00 a.m. Los Alamos time) I woke to hear the General’s voice at the other end of my telephone, instructing me to go to his Washington office immediately.

The emergency, I discovered, was a chemical explosion at a gas diffusion plant on the East Coast; Groves wanted to question me about the possibility of serious malfunction in our separation process. After a preliminary discussion, Groves assembled a group of his staff at a long table. I sat on his right and was kept wide awake by a barrage of hypothetical questions while the General slouched, with eyes closed, seemingly half asleep. Periodically, he would open both eyes, look me square in the face and state, “But after all, Professor, this is only theory.”

Toward the beginning of the third hour of this inquisition, a colonel at the end of the table asked if it were not possible that all the U235 atoms might assemble at one end of the apparatus by pure chance, and thereby cause a nuclear explosion. “Of course,” I answered, “this is a possibility, but it is as probable as that all the air molecules in the room will assemble under the table, causing us all to suffocate.”

Groves immediately sat up and said, “But Doctor, you did say this is possible.” Conant intervened with, “What Dr. Teller intends to say is that such an assembly is really quite impossible.” From this moment on, General Groves treated me with exquisite politeness. Apparently, I had passed his test as to whether or not I could be trusted.

Neither through contact nor through rumor did I ever learn of Grove’s sense of humor. Yet in reading his book, I discovered not only that he was quite sufficiently endowed with one but that he could laugh at himself.

[…]

About 1943, General Groves, visiting the Berkeley Radiation Laboratory which was separating U235 by electromagnetic means, attempted to spur Lawrence on by saying to him, “Your reputation is at stake here.” Later over a nice rum drink, Lawrence said to him, “You know, General, my reputation has been made, but yours is at stake here.” Groves did not respond. However, a couple of years later, Groves in addressing a group at Los Alamos commented: “When all of this is over, you will go back to your universities, regardless of the outcome, but my reputation is at stake here.”

[…]

Toward the end of my visit, Sir James Chadwick, who had headed the wartime British scientific delegation to Los Alamos, invited me to dinner at his home in Caius College. Sir James was well-known in the scientific community for his taciturn nature, but his wife was a charming conversationalist. She drew me out about our mutual friends and acquaintances from Los Alamos, and eventually inquired about General Groves. My response, I am afraid, reflected an unflattering opinion of him.

At that point, a miracle occurred. Sir James, who had spoken perhaps twenty words that evening, became talkative to the point of being almost uninterruptible. He told me most emphatically and repeatedly that the atomic bomb project would never have succeeded without General Groves. I pointed out how often Groves had made plain his dislike of the British. Sir James brushed aside my comment. That made no difference. What was important, Sir James went on, was that Groves understood the overriding importance of the project better than some of the leading American scientists. Without Groves, he said, the scientists could never have built the bomb.

I have rarely seen anyone—even an ordinarily effusive talker—so insistent on making his point. However, Sir James’s tirade carried no trace of reproach for my inappropriate remark about General Groves. At the end of the evening, my host walked me back to my inn. On parting, he told me to remember what he had said as I might “have need of it.”

Shortly after this evening, I was back in the United States and gained some new information. It then dawned on me that during our conversation Chadwick probably had known what I had just learned: the Soviets had exploded an atomic bomb. Chadwick knew that American scientists, who had less direct an experience with World War II than their British colleagues, many of whose homes and families were in peril, had not realized the urgency and importance of the atomic bomb project. General Groves, on the other hand, having considered military matters throughout his career, knew exactly what it meant to be inadequately defended.

[…]

Today, national security and technology have become inseparable. Yet the gulf between the military establishment and the scientific community is as great as ever. General Groves was one of the pioneers who, with difficulty but ultimate success, managed to throw a bridge across the abyss.

I do not see much hope for the survival of our democratic form of government if we cannot rebuild that bridge made by General Groves and J. Robert Oppenheimer. We must find ways to encourage mutual understanding and significant collaboration between those who defend their nation with their lives and those who can contribute the ideas to make that defense successful. Only by such cooperation can we hope that freedom will survive, that peace will be preserved.

Sinaloa cartel used phone data and surveillance cameras to find FBI informants

Sunday, July 6th, 2025

A Sinaloa drug cartel hacker was able to obtain an FBI official’s phone records and use Mexico City’s surveillance cameras to help track and kill the agency’s informants in 2018, the U.S. Justice Department said in a report issued on Thursday:

The report said the hacker identified an FBI assistant legal attaché at the U.S. Embassy in Mexico City and was able to use the attaché’s phone number “to obtain calls made and received, as well as geolocation data.” The report said the hacker also “used Mexico City’s camera system to follow the (FBI official) through the city and identify people the (official) met with.”

The report said “the cartel used that information to intimidate and, in some instances, kill potential sources or cooperating witnesses.”
