<p>It’s not how any of it works.<p>How do you determine to whom an IP is even registered to? They get sub-leased all the time.<p>The best you can do is check who has administrative control over the prefixes RIR info, but that doesn’t mean that anyone with control is the factual user of the IPs.<p>You could check the IRR for the ASN and base it on that, but still.<p>There's also no way to actually know _where_ an IP actually originates from. Only its AS path.<p>The DFZ contains all prefixes announced everywhere, for the internet is completely decentralized.</p>

<p>> we don't want IP's from Frankfurt showing up somewhere in Dubai<p>what do you mean, IPs from Frankfurt?<p>IP addresses are just IP addresses, they know no geographical boundaries. In RIR DBs you can geolocate them to wherever you want. Which is the entire reason why Geo IP DBs even exist - they triangulate.</p>

<p>They probably did, and just determined that it would be fun.<p>The other week I had a fun project to implement IPv6 support in TempleOS. I did stop to think whether I should, and determined that absolutely not.<p>I asked Claude to start planning on doing it. It started referencing ZealOS, which is a fork of TempleOS and already has a functioning TCP stack.<p>That's when I determined that it would no longer even be fun, because someone else had already done all the heavy lifting, and gave up.</p>

<p>I’d argue that with explosives it’s significantly above zero.<p>But with bioweapons, yeah, that should be a solid zero. The ones actually doing it off an AI prompt aren't going to have access to a BSL-3 lab (or more importantly, probably know nothing about cross-contamination), and just about everyone who has access to a BSL-3 lab, should already have all the theoretical knowledge they would need for it.</p>

<p>The cat is out of the bag and there’s no defense against that.<p>There are several open source models with no built in (or trivial to ecape) safeguards. Of course they can afford that because they are non-commercial.<p>Anthorpic can’t afford a headline like “Claude helped a terrorist build a bomb”.<p>And this whataboutism is completely meaningless. See: P. A. Luty’s Expedient Homemade Firearms (<a href="https://en.wikipedia.org/wiki/Philip_Luty" rel="nofollow">https://en.wikipedia.org/wiki/Philip_Luty</a>), or FGC-9 when 3D printing.<p>It’s trivial to build guns or bombs, and there’s a strong inverse correlation between people wanting to cause mass harm and those willing to learn how to do so.<p>I’m certain that _everyone_ looking for AI assistance even with your example would be learning about it for academic reasons, sheer curiosity, or would kill themselves in the process.<p>“What saveguards should LLMs have” is the wrong question. “When aren’t they going to have any?” is an inevitability. Perhaps not in widespread commercial products, but definitely widely-accessible ones.</p>

<p>> It's pure logic that Tesla has to pursue bets that would justify billion dollar valuations and being a car company isn't that.<p>But it's make-believe. Tesla is a car manufacturer. They haven't shipped anything else other than cars. And they even suck at making cars these days. Tesla Semi? All but dead. The new roadster? Also dead. Full Self Driving? Doesn't exist. Robotaxis? Even if they got them to work, at this point the brand is too toxic for widespread adoption of those.<p>They could have persisted at being a disruptive car manufacturer and still held a several hundred billion dollar valuation. Now they are a very mediocre car manufacturer, with their only actual success being conning everyone into believing that they are a bleeding-edge tech company so their $1.5Bn valuation seems justified.</p>

<p>Tesla will become a case study on how to completely waste the first-mover advantage.<p>For many people, the very term EV itself is still ubiquitous to Tesla.<p>And somehow Tesla is still worth more than every other non-Chinese automaker combined. $1.5T.<p>GM? $80B. Stellantis? $40B. Toyota? $280B. Mercedes-Benz? $60B. BMW? $55B. Volkswagen Group? Also $55B.<p>I’m sure I’ve missed plenty of others, but I could miss some 18 $50B automakers, and Tesla would still be worth more than all of them combined.<p>If Tesla was valued fairly, it would probably be at the tune of $5B. But I’ll never bet against it, because the markets can remain irrational for longer than I can remain solvent. And for some unbeknownst to me reason, the markets value Tesla as a hot tech company, not a 3rd rate automaker, which is what it actually is.<p>And to add insult to injury, even GM Super Cruise is widely renowned as better and safer than Tesla’s current “FSD”.</p>

<p>The funniest part about Windows Server licensing that I find is the requirement to have CALs (Client Access Licenses) - $5/mo a pop for each device using _any_ service provided by the Windows Server.<p>You run your Windows Server as a DHCP server? That's $5/mo for the clients to get a DHCP lease.<p>Of course, one CAL covers all services for the entire client, but it's still funny to me.</p>
