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.

If we want billionaires to pay their fair share, we should start by eliminating some of the tax loopholes that allow them to avoid paying the taxes that less wealthy people have to pay.

These loopholes are many, they favor the ultra wealthy, they absolutely can be eliminated, and doing so is far less problematic than this wealth tax proposal.

The proposal here was not for the government to BUY the stocks, just like anyone else. It was for the government to TAKE the stocks. For free. In return for nothing.

And, regardless, the key difference between capitalism and socialism (in this context) is who owns the means of production: private citizens, or the government? Once the government owns the means of production (whether they bought it or seized it), then that qualifies as socialism.

This slider isn't exactly boolean. It is totally possible for the government to own some of the means of production, without owning all of it. That just means that we have a mix of socialism and capitalism going on.

You should give a 90 day window so you don't become an enabler of crime.

The bug bounty is there to incite you to look for bugs at all. If there isn't a bug bounty program, or you don't think it will pay out, then don't go looking for bugs.

If you find a bug anyway, and want to do the right thing, then you responsibly disclose it (whether you get paid or not). If you don't want to do the right thing, then you just ignore the bug and don't publish it.

If you publish the bug without giving the company 90 days first, then you are harming all the innocent people who are using that product (by telling criminals exactly how to exploit an unfixed bug). That is an evil thing to do. In some places, lawsuits might fly your way because of something like that.

You should still disclose the vulnerability to the company, and tell them they have 90 days before you publish it.

If you just publish it, you are putting all their users at immediate risk of being exploited by criminals who view your publication and immediately weaponize it. That is why you must disclose it to the company first, so they can get a fix out BEFORE you go public with it.

If you are unwilling to do this, then don't publish the finding.

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).
