The first half of the article says "namespaces, cgroups, and seccomp aren't 'security boundaries' because if the kernel had a bug it could be used to escape from a sandbox". Then in the second half it says "use gvisor and do all this other stuff to avoid these problems." This presentation feels kind of dishonest to me because the article avoids acknowledging the obvious question: "well what if gvisor has a bug then?" I mean, sure, another layer of sandboxing that is simpler than the other layers probably increases security, but let's not pretend like these are fundamentally different approaches.

If the successful people you meet in real life are nice and you see lots of meanness on the internet, it probably just means that anonymity causes meanness.
orangea commented on Satya Nadella: "We need to find something useful for AI" pcgamer.com/software/ai/m... · Posted by u/marcyb5st
This will sound pedantic but I'll explain why it matters: the exact wording is "We need to do something useful with AI", because the current (editorialized) submission title (of an already slanted article) makes it sound like people don't know what to do with AI.
We already know many useful things to do; there are already 10,000 startups (9789 out of YC alone, 4423 of which are coding-related) doing various ostensibly useful things. And there a ton more use-cases discussed in the comments here and elsewhere. But because of the headline the discussion is missing the much more important point!
Satya's point is, we need to do things that improve people's lives. Specific quotes from TFA:
>... "do something useful that changes the outcomes of people and communities and countries and industries."
> "We will quickly lose even the social permission to take something like energy, which is a scarce resource, and use it to generate these tokens, if these tokens are not improving health outcomes, education outcomes, public sector efficiency, private sector competitiveness, across all sectors, small and large, right?" said Nadella. "And that, to me, is ultimately the goal."
Which is absolutely right. He's the only Big Tech CEO I've heard of who constantly harps on the human and economic benefit angle of LLMs, whereas so many others talk -- maybe in indirect ways -- about replacing people and/or only improving company outcomes (which are usually better for only a small group of people: the shareholders.)
He's still a CEO, so I have no illusions that he's any different from the rest of them (he's presided over a ton of layoffs, after all.) But he seems to be the only CEO whose interests appear to be aligned with the rest of ours.

I don't think you meant "ostensibly".

Every time I try to understand algebraic geometry I get stuck at just beyond varieties and ideals. I can't even work my way up to chain complexes and homologies to even get a hold on the content. Honestly functors and natural transformations, I dont grok either, so its greek to me.
Like whenever i'm working through definitions or content it all makes sense. But not being a working mathematician it all just blurs away into abstract nonsense that I can't organize internally.
Learning homological algebra is a long way away from learning about varieties and ideals in any sensible order in which to learn material. You have to do a lot of work in between in order for homological algebra to seem motivated. Sounds like you ought to try an introduction to algebraic topology.
Could someone please point me to a concise summary of controversy around DHH? I have seen a few references recently, but I am out of the loop.
Why not read the source and decide for yourself? Here's a blog post linked in the article, as a start: https://world.hey.com/dhh/as-i-remember-london-e7d38e64
> Well, dhh considers torrents outdated (I’m not kidding, check the tweet), so it’s only officially being offered as a single download from a Cloudflare server. Which sounds cool until you’re on a weak-ass connection in constant danger of dropping halfway through the download.
That has nothing to do with bittorrent vs http; use a download manager instead of a browser.

How does this compare to Asahi in 2025? In my experience, Asahi's been great
Asahi is useless to me, and I would assume many others, without USB-C display support.

I live in one of the areas they are actively testing/training in. Their cars consistently behave better and more safely than most human drivers that I’m forced to share the road with.
As semi-autonomous and autonomous cars become the norm, I would adore to see obtaining a drivers license ratchet up in difficulty in order to remove dangerous human drivers from the road.
Don't you think that the vast majority of dangerous human drivers would be perfectly capable of changing their behavior during a driving test? Even without any malicious intent most people would be more careful during a test.
