It does if the person making the statement has a track record, proven expertise on the topic - and in this case… it actually may mean something to other people
Yes, as we all know that unsourced unsubstantiated statements are the best way to verify claims regarding engineering practices. Especially when said person has a financial stake in the outcomes of said claims.
I have zero financial stake in Anthropic and more broadly my career is more threatened by LLM-assisted vulnerability research (something I do not personally do serious work on) than it is aided by it, but I understand that the first principal component of casual skepticism on HN is "must be a conflict of interest".
Someone's credibility cannot be determined by their point counts. Holy fuck is that not a way to evaluate someone in the slightest. Points don't matter.
Instead look at their profile...
Points != creds. Creds == creds.
Don't be fucking lazy and rely on points, especially when they link their identity.
I wasn't at all saying that points = credibility. I was saying that points = not unknown. Enough people around here know who he is, and if he didn't have credibility on this topic he'd be getting down voted instead of voted to the top.
Is that meaningfully different? If you read malfist's point as "tptacek's point isn't valuable because it's from some random person on the internet" then the problem is "random person on the internet" = "unknown credentials". In group, out group, notoriety, points, whatever are not the issue.
I'll put it this way, I don't give a shit about Robert Downy Jr's opinion on AI technology. His notoriety "means nothing to anybody". But instead, I sure do care about Hinton's (even if I disagree with him).
malfist asked why they should care. You said points. You should have said "tptacek is known to do security work, see his profile". Done. Much more direct. Answers the actual question. Instead you pointed to points, which only makes him "not a stranger" at best but still doesn't answer the question. Intended or not "you should believe tptacek because he has a lot of points" is a reasonable interpretation of what you said.
Pointing to the profile leads someone on the path of understanding why to trust tptacek on security issues. Pointing to his points on HN explains why lots of users here already know that he's credible in this area and will recognize his username and upvote his comments on this topic and know better than to blindly accuse him of being a just a random person on the internet.
The problematic, ignorant comment that has been flagged asserted that what tptacek says "means nothing to anybody else", which is a very wrong statement about his role in the HN community.
I don't get your argument. That everyone should know and recognize our community celebrities? That seems really out of touch. Given the age of their profile I'm assuming they just spend more time touching grass.
Either way I'm not sure what your point is. You didn't answer their question. The one you replied to. I you're in defensive mode but no need to defend, I'm not going to respond anymore.
How is this whole comment chain not a textbook case of "argument from authority"? I claim A, a guys says. Why would I trust you somebody else responds. Well he's pretty well known on the internet forum we're all on, the third guy says, adding nothing to the conversation.
It is an argument of authority but that's not always a bad thing. I think it's a bit out of keeping with the supposed point of this site (ie intellectual inquiry) but when it comes to rapidly evolving technologies like this one it can still add value on the whole.
and its ridiculous that someone's comment got flagged for not worshiping at the alter of tptacek. they weren't even particularly rude about it.
i guarantee if i said what tptacek said, and someone replied with exactly what malfist said, they would not have been flagged. i probably would have been downvoted.
why appeal to authority is totally cool as long as tptacek is the authority is way fucking beyond me. one of those HN quirks. HN people fucking love tptacek and take his word as gospel.
Sounds a bit like that Dilbert where the marketing guy has sold a new invisible computer and is telling the engineers to now do their job and actually make it.
Not at all. It literally is just an engineering problem. Space radiators exist for decades. You can build one big enough for any heat load, it's purely a matter of cost - there are no unknown problems there.
You can argue that the current costs are too high and you need new physics or new inventions to bring it down to something more reasonable, yes. But the basic science of radiating heat in space is known. There are proposals for alternative designs that might work better. The question is how much can you build them for and what's the resulting cost profile. Which is an engineering question.
people who do understand thermodynamics will already understand the problem, but innocent people who don't understand thermodynamics should not be misled by poorly chosen examples presented as proof.
I didn’t claim that eclecticlight writes cheap dunk.
But this article, which starts with
> That’s a question I’m asked repeatedly, which this article tries to answer.
doesn’t actually _try_ to answer the question. It just stops at SSV and draws a meaningless comparision with macOS 9. It also has several factual inaccuracies in there. Notably, the claim that macOS is not UNIX, and the implication that Unix systems must somehow be free and open-source (virtually all Unixes of the day were proprietary & closed source).
