Comment Re:3D printing whole rockets was such a dumb idea. (Score 1) 47

Oh god. If I spent enough time digging through my ancient Slashdot posts, somewhere back there there are posts of me going, "While I loved the strategy behind Falcon 9, I'm really not keen on this plan to make Starship out of huge carbon fibre tanks, that sounds like a really failure-prone solution..." I'm glad they only spent like a year on that idea before deciding it was dumb; somewhere back there there's also a bunch of posts of me cheering their switch to steel ;) . SpaceX still keep having random COPV problems (most of which they don't even make themselves). Not too encouraging for the notion of the cold gas thruster add-on to the Roadster, where the plan is to replace the back seat with COPVs, so you have a COPV right behind your head.

Electron has been getting by on CF, and honestly I'm impressed, but they've also been only working with very small launch vehicles thusfar. We'll see how neutron goes...

Don't get me wrong, there's a lot to say about printing small rocket parts, such as for the engines. But they were printing basically sheet metal cylinders, which is such an immensely slow and inefficient way to go about it, and it left them with parts that were heavier and less aerodynamic (rougher surface). Crazy that idea ever got any funding.

"SapceX has got to be a huge scam too" - SpaceX launches the vast majority of the world's commercial cargo to orbit. The Falcon 9 FT has the highest success rate of any rocket with a statistically significant number of launches under its belt, and is dirt cheap. SpaceX's core operations are roughly breakeven, but that's including subsidizing the development of Starship. Starlink is a money printer.

There are lots of things sketchy about the SpaceX IPO, to say the least, but SpaceX, as a company, has been extremely successful with rocketry.

The funny thing was that I knew him for like six months online before I realized he was fully paralyzed. He's been covered in the Finnish press a number of times. Amazing guy. Up until recently he was living in a house he built himself before ALS struck, but the medical service decided he was too far away and he had to move closer. You lose a lot of control over your life with ALS.

He wrote a book about nuclear safety engineering recently, which is a fascinating read, and which I strongly recommend.

Motor neurons dying != brain control of motor neurons dies.

Anyway, you don't need a brain-computer interface for an ALS patient to work. I have a friend in Finland with ALS who works as a consultant on safety for a nuclear reactor startup (he was a nuclear safety engineer before becoming paralyzed). All it takes is an eye tracker.

The biggest problem is the typically short and unpredictable lives of ALS patients. He has lived abnormally long (I think something like 13 years now), but a large part of that is due to him thinking like a nuclear safety engineer (backup on backup on backup, training his nurses to have zero tolerance for error, etc), and still has a close call like once per year or so, and I regularly worry when I don't see him online in a while that something happened that killed him. A tube comes off a life support system. A nurse forgetting to reconnect something. A mucus plug in his airways. Etc. ALS patients' lives are fragile. He does CAD design for parts on his computer (it's too hard to do it with the mouse using the eye tracker, so he designs the shapes programmatically) and orders them 3d printed to correct any deficiencies he finds in his support systems.

ALS patients also have to constantly fight the medical system. Even in a place like Finland that will actually do long-term care for ALS patients (which is very expensive), it shows that it would be much more convenient for them if those danged ALS patients would choose to die (and there's often pressure put on them to do so). One of my friend's goals is to outlive a doctor who told him he would only live a year or two put a lot of effort into getting him to choose death. It was a battle to get long-term ventilator care. It was an even bigger battle to get to use a cough machine and to be able to control the settings on it; without regular, meaningful cough support, your lungs fill with mucus, and you'll probably eventually die of a mucus plug, pneumonia, or whatnot.

By contrast, ALS patients today can actually live a decent life using eye trackers. It's not like before when you had to tediously spell out things one character at a time to a helper holding an E-tran frame. Given that 1 in 500 people will get ALS at some point in their life, we really should be allocating a lot more money toward researching cures, even if purely from a cost-saving perspective.

(One final note: if anyone here starts getting peripheral weakness and worries its ALS: your instinct will be to exercise more. Do just the opposite. If your peripheral neurons are dying, the last thing they need is more work. ALS overwhelmingly strikes active people - one researcher I was reading noted that in her entire career, she's never met a couch potato who got ALS. Take it easy, see a doctor immediately, and if it is ALS, start preparing early, but know that you do not have to be forced to choose to die, so long as you can get care. You can live a decent, productive life if you choose to).

Submission + - Alan Turing developed a portable voice encryption device (popularmechanics.com)

smooth wombat writes: Alan Turing, one of the more famous people who worked at Bletchley Park to decipher the German Enigma coding machine, was also working on a separate project. His private papers, known as the Bayley papers for his assistant Donald Bayley who held onto the papers until his death in 2020, reveal Turning had produced a working model of a portable voice encryption device. He even demonstrated it by using a Winston Churchill speech recording.

“Weighing just 39 kg, including its power pack,” Copeland summarizes, “Delilah would be at home in a truck, a trench, or a large backpack.”

Turing’s work at Bletchley Park actually informed the Delilah experimentation he was doing at Hanslope Park, and not just because he used Red Forms, the Army-issue sheets Hanslope staffers were meant to use to alert Bletchley staffers to enemy signals, as his personal scrap paper for Delilah experiments. He drew inspiration from one of the German cipher machines they had decoded at Bletchley; not the famed Enigma machine, but rather the SZ42. While the former relied on Morse Code, the latter utilized a 5-bit telegraph code, which Copeland notes “was a forerunner of ASCII and Unicode and is still used by some ham radio operators.”

The SZ42 produced an obscuring key of telegraph characters, with an identical key produced to both the sender and receiver. If it could be done for text, Turing reasoned it could be done for sound as well.

This is the part of the story where one might say “Well, I’ve never heard of Alan Turing’s voice encoder, so the experiments must have failed.” But remarkably, they didn’t. Turing and Bayley actually did create their Delilah, and even demonstrated it using a recording of a Winston Churchill speech, “successfully encrypting, transmitting, and decrypting it.”

Instead, the reason Delilah fell to the wayside of history isn’t because it was a failure, but rather because it simply wasn’t needed anymore. By the time Turing had built and demonstrated his device, the war was over. What good was a portable voice encryptor if you had no major enemies trying to intercept your calls, the government reasoned. So funding for the project stopped, and Turing’s two-year experiment ended with a whimper. Turing’s time as an electrical engineer at Hanslope Park became a footnote in his story, if even that.

Whether Anthropic was trying to hype about Mythos / Fable or not (and FYI, it is a pretty big leap forward), they absolutely did not want to get public access shut down. The US government very much seems to want to have exclusive access to it for now.

Also, to clarify the "jailbreak": They took open source projects that had known vulnerabilities, as well as deliberately introducing vulnerabilities into some other projects, then asked Fable to fix them, and then asked for test scripts to demonstrate that the exploits could no longer be exploited - the implication being that they could then use those exploits against unpatched systems. But what's the logic here? The challenge isn't "how to write exploits against known bugs", any model can do that. The challenge is finding the bugs - something Mythos / Fable has proven better than previous models at. Even if Fable refused to write said test scripts, it would automatically downgrade to Opus 4.8, and then *Opus* would have written those test scripts. Or any other model out there could do it, including free open source ones that can be safety-abliterated at will.

Submission + - Trump's "Made in the USA" Phone is just a reskinned HTC U24 Pro 1

necro81 writes: The heavily promoted, $499 T1 "Trump Phone" was originally said to be "Made in the USA" and ship in September 2025. Later, that was downgraded to "Assembled in the USA". Given the Trump Organization's lack of engineering or supply chain expertise, many assumed the "T1" would just be a private-label phone made by someone else. After a number of delays, the first phones are finally shipping.

iFixit has performed a teardown and concluded that the T1 is a just gold-painted 2024 HTC U24 Pro — a device from a Taiwanese company, probably using mainland China design and supply chains. In collaboration with NBC News, the iFixit team examined both phones using CT scans, side-by-side teardowns, and even reassembled a working T1 using a U24 Pro main board. As for "assembled in the USA", that may be true, in the same sense that your phone's repairman can "assemble" a phone from a handful of subassemblies sourced from someone else. Or it may have been assembled in Guangdong, China like the other U24 Pros.

iFixit sums it up: "What you have is not an 'American-Proud Design', but a phone designed in China, made in China, with the vast majority of parts sourced from China. I’m failing to find any stirring of American pride within me. I’ve certainly felt it before, so I can confirm that it is absent at this time."

And again, that's not to imply that they have any particular "mastery" in this specific case. Obviously, if they just typed "write the essay for me" into ChatGPT and submitted it without reading it, then they're not going to have learned much of anything from that. The question is, however, what did they do with their time instead? Because their brain was learning that instead.

The correllary to "use it or lose it" is that the brain isn't just going idle, it's refocusing its efforts on other things that you are "using" instead.

The average person today could hardly identify all the wild edible plants in their area, change a horseshoe, or build a proper barn, like their ancestors hundreds of years ago could.

By contrast, their ancestors hundreds of years ago probably couldn't read.

Brains don't just go idle; they just refocus on different things. A wealthy Victorian often pursued a life of a polymath, seeking varied intellectual pursuits and sometimes making great discoveries, but they could probably scarcely tell you how to mend a shoe or even change a nappy - that was their servants job.

Also, it's quite the spin to present low MRI activity as "reduced function". It's commonly literally the opposite. If you present a novice with a task they're not used to, and an expert with the same task, the expert will tend to show much less activity than the novice, as the novice has to think harder to accomplish it, whereas it's become rote for the expert. Low activation on a task is commonly a sign of cognitive efficiency.
