dotnet00··on DOJ seizes $15B in Bitcoin from 'pig butchering' scam based in Cambodia
Crypto anonymity is still possible if you don't plan to spend your ill-gotten millions or billions particularly quickly. But, of course, you don't get to having a massive active criminal empire that way.
dotnet00··on America is getting an AI gold rush instead of a factory boom
The V100 is ~8 years old and AFAIK mostly not that common anymore, but the A100 is ~5.5 years old now and is still very commonly used, it's maybe the most common HPC cluster GPU. On the consumer side, 3090s are still very popular, representing a good balance between cost, performance and efficiency (this is mostly due to 4090s and 5090s being much more expensive).
dotnet00··on SpaceX launches Starship megarocket on 11th test flight
I had considered adding how HN's darling's CEO, Tim, was also doing his part to support the American gestapo but figured that'd just be whataboutism (I think Zuckerberg gets hated on relatively similarly to Musk).

I just don't think every thread about SpaceX needs to be shitted up. It's unpleasant, like someone barging into a thread about some new exciting development/project in India or other developing country to rain on everyone's parade by saying that they should spend that money on getting everyone a toilet.

As you say, it's just difficult to tell, the tile loss seems less dramatic than many used to expect back when the heat shield was relatively early in design, but ultimately only SpaceX knows how much they're passively losing during the coast phase.

All I'm saying is that that's one more factor besides relight that I think will need to be sorted (it might already be sorted, I wouldn't know) before orbit.

I have no idea what criminal wrongdoing you're referring to, and as for the other point, it's just so overdone at this point. Every time SpaceX is mentioned, you guys feel the need to shit up the discussion with your cynicism and repeating of things everyone has heard a million times as if it's novel insight.

We all know Musk is at best an absolute idiot when it comes to politics who's being manipulated by sycophants, and at worst, he's an evil fascist that is completely fine with wrecking everything that lets his companies actually be successful. But a lot of you guys think that's an excuse to pretend that he doesn't deserve any credit for anything. Even just acknowledging that he has done useful things in the past is apparently fawning over him.

By putting his wealth into a vision, I mean all the test flights, being much more tolerant of failure, betting everything on Starlink. We're at flight 13, and likely at least flight 16 before anything orbital, likely into the upper 20s before reliable refueling and non-Starlink payloads. Most other rich people haven't done much besides minimally funding small startups or dead end joyrides.

Bezos has been somewhat similar, he has been pouring billions into BO, and while BO has moved at a slower pace, he's clearly committed for the long term too, considering all the investments into things that only make sense if New Glenn acheives reliable booster reuse (the giant futuristic rocket factory, Project Jarvis, the lunar cargo lander).

I think the tile loss rate will still be important to them before that. Even in such low orbits, any tiles lost would take some time to come down (and might even survive all the way down).

If they can make it so they only lose tiles when in a suborbital trajectory, they may be safe to begin deploying real Starlinks as soon as V3 has proven engine relight.

I would love such a society, but I think the way space funding has been in most parts of the world shows that most people are just not good judges of what is and is not worth spending on.

It seems very few people actually understand the importance of funding R&D that isn't directly improving their life, such that it takes some stubborn rich people to actually show that something is worth doing. Kind of like other countries all working on Falcon and Starship inspired rockets after seeing that the concepts can work.

As other examples, we have particle accelerators (everyone knows about the colliders like LHC and assumes they're luxury projects with no relevance to improving lives, yet they led to the development and side-by-side refinement of synchrotron light sources, which are very important for modern science) and medical tech like what led up to mRNA vaccines and Ozempic.

I would say we need a society that trusts experts and also holds said experts accountable, but then again, most of SpaceX's founding employees were not conventional aerospace experts, which was part of why they were able to question a lot of the corrupt/inefficient practices that traditional aerospace people dismissed as being standard and necessary practice.

I think it depends on which specific step fails. The farther into flight it happens, the narrower the area over which the debris is spread. But, I think being over the entire ocean is unlikely, since the trajectory intersects with the planet, and that intersection point would also have to be in the ocean.

Correction: the trajectory only intersects with the planet prior to engine relight testing. After that it's at ~50km [1] (though to be fair, if they make it safely through the relight, all testing so far shows they're likely to make it through most of reentry)

Not every mention of Musk needs to be accompanied by a disclaimer of not supporting his idiotic self-defeating politics. This isn't reddit.

Speaking of politics though, it was a bit jarring to see the "USA! USA!" chanting. I get the intent (disliking the government doesn't mean disliking America), but it's kind of awkward to see a large crowd of immigrants doing it as the admin their boss supports is pretty blatantly harassing immigrants regardless of citizenship.

He deserves at least some credit, considering that he and Bezos are the only billionaires actually willing to put their wealth into chasing a vision. Books documenting SpaceX's early days make it pretty clear that Musk had a pretty significant role in putting in place the kind of thinking that has allowed SpaceX to blow open the commercial space market.

Both also have at least some understanding of what they're paying for considering the tours and testimony from former employees. They also frequently thank the employees for their successes.

I think they're holding off on going fully orbital until the Ship engines are relatively stable (they try out different things with them almost every flight, and V3 has a significantly improved engine design too), tile losses are relatively under control and they're either ready to start testing Ship catches, or have tested them.

Right now they're in a comfortable testing regime, getting up to near-orbital speed to be able to verify reentry in realistic conditions, while having the freedom to test dummy payload deployments and freedom to risk losing tiles since they will all definitely burn up or splash down within minutes of the ship reentry rather than floating around in orbit for some time.

If they go orbital, they had better be sure they won't leave a ton of tiles behind, and that they will be able to perform a controlled deorbit.

dotnet00··on More random home lab things I've recently learned
With containers, making backups seemed to become impractical with large libraries, since it seems to copy files individually?

I had to switch to VM because of that, passing through the GPU.

dotnet00··on Ancient Patagonian hunter-gatherers took care of their injured and disabled
People are used to thinking that humans were animalistic savages right up until their favored religion or ancient city-state popped up, believing that the hunter-gatherer existence would've been so harsh that there was no room to care for vulnerable members of the group.

What are books?
dotnet00··on After the AI boom: what might we be left with?
Taking the example of egyptian archeology, if you're reading the work of someone who is well regarded as an expert in the field, you can trust their word a lot more than you can trust the word of an AI, even if the AI is provided the text you're reading.

This is a pretty massive difference between the two, and your narrative is part of why AI is proving to be so harmful for education in general. Delusional dreamers and greedy CEOs talking about AI being able to do "PhD level work" have potentially ruined a significant chunk of the next generation into thinking they are genuinely learning from asking AI "a few questions" and taking the answers at face value instead of struggling through the material to build true understanding.

dotnet00··on After the AI boom: what might we be left with?
You've done nothing but reuse the Sam Altman/Elon Musk playbook of making wild and extremely vague statements.

Maybe say something concrete? What's a positive real world impact of LLMs where they aren't hideously expensive and error prone to the point of near uselessness? Something that isn't just the equivalent of a crypto-bro saying that their system for semi-regulated speculation (totally not a rugpull!) will end the tyranny of the banks.

I'm hoping that it's sarcasm to be invoking a machine god while calling the non-believers irrational.

It looks like they're planning on funding it through circular purchase agreements and looting the rest of the world.
dotnet00··on After the AI boom: what might we be left with?
Reminds me of crypto/Web-3.0 hype. Lots of bluster about changing economic systems, offering people freedom and wealth, only to mostly be scams, and coming with too serious inherent drawbacks/costs to solve many of the big problems it promises to solve.

In the end leaving the world changed, but not as meaningfully or positively as promised.

dotnet00··on Microsoft only lets you opt out of AI photo scanning 3x a year
I imagine you'd add more heuristics and various types of hashes? If the file is just sitting there, rarely accessed and unshared, or if the file only triggers on 2/10 hashes, it's probably a false alarm. If the file is on a public share, you can probably run an actual image comparison...
dotnet00··on Starship's Final Moment Before Everything Changes [video]
It seems to just be Marcus' usual clickbaity style. It's just about the test flight on Monday, which is supposed to be the last one for Block 2. After that they'll be on to Block 3 with significantly improved engines (they should fare better through re-entry, particularly on the booster), and some big tweaks to the booster and ship control surfaces.

After proving they can successfully catch boosters, they haven't been bothering with it so far because they're all already obsolete, and with the Ships, they only ironed out the major flaws with block 2 at the last test flight. So, one more test to gather more data, then on to some more downtime putting the next block upgrade through all the ground testing again.

dotnet00··on Daniel Kahneman opted for assisted suicide in Switzerland
By that logic we should invoke the death penalty for everyone who has been sentenced to life in prison and has exhausted all their appeals, or any seniors convicted of a crime.

Their life probably won't improve anymore, and in the latter case they're going to die in a few years anyway, so might as well just lighten the load on society?

dotnet00··on Daniel Kahneman opted for assisted suicide in Switzerland
Inheritance, and for the government/insurance companies, there's the incentive of the one-time cost of euthanization being lower than the cost of care for the poor, disabled and/or the terminally ill.
dotnet00··on Daniel Kahneman opted for assisted suicide in Switzerland
This is such a cruel perspective, implying that he'd be better off dead, for what, 3 years of inconvenience to his community, despite the previous 80 years being spent contributing positively to it?

You even literally show that he isn't solely remembered for those last 3 years of his life. We owe people like that care and understanding, not murder framed as mercy.

It's always so painful to see old people around who are clearly living alone, forced to do everything themselves, having to ask strangers for help because they're afraid of being a burden, and their actual children can't find time for them. Only to now see people actually supporting murder because old people become a burden for a couple of years near the end of their life.

dotnet00··on Daniel Kahneman opted for assisted suicide in Switzerland
Being braindead is pretty different from having Alzheimers. How do we account for people who change their minds? Do we just forcibly murder them anyway?

The entire issue they're pointing to is that deciding that someone's existence is sufficiently tormented is difficult and morally fraught.
dotnet00··on Regarding the Compact
Pretty massive difference between "the federal government is using its influence to try to compel academia into bending the knee to it and it's fascistic methods of operating" and "most academics aren't in favor of the party that still doesn't believe in vaccines, hates them or their colleagues for having the wrong skin color and doesn't see any value in the liberal arts".

dotnet00··on California law forces Netflix, Hulu to turn down ad volumes
Plex, as a business, is already in a tough spot because it's mostly used to stream pirated media, and if they make too many overt moves towards making piracy easier, media companies might start going after them.

Thus all the stuff to haphazardly integrate streaming services. Selling it as a preconfigured kit might be risky.
