Also they only have dark mode in the app, even though the app is (or was) clearly not native anyway.

If you were just a little bit serious you wouldn’t be discussing this on a site run by Y-Combinator!

(the “angry” comments are so tiring)

What do you think the exec job is? What do they do every day, every working hour? And how will AI replace that?

Well done!

I do hope AI will really allow folks to build products with better UX. The problem traditionally is that the UX gets "stuck" - gmail, google maps, they cannot really change because of user's expectations and the big orgs that run them as products. And building new things from scratch was fairly expensive. But now with AI (and modern UI tooling) the equation is at least partially changing.

I don’t think Alaska has the kind of UBI people are discussing here? You probably cannot survive on $1000/year. In that situation it doesn’t seem much different to social programs standard in Europe + progressive tax.

You are answering my question - you posit that communism failed because people like to own property (and form social hierarchies) - and UBI doesn’t prevent those.

I’m not sure this is the case. Especially since people did form social hierarchies and did own propety in communist/socialist regimes of the Eastern block.

One might argue that UBI is incompatible with human nature, because most humans require a sense of worth, which paid work provides (to most). Take away the motivation, will the self-worthiness remain? (especially when thinking about _most_ people, not the struggling artists who wished they could pursue art without the burden of bills).

I’m not sure about this at all. I just think drawing the parallels and discussing communism failure modes is interesting for the discussion of UBI.

We have been on this path at work. But I challenge everyone to consider what you lose with MD vs Confluence (et al). It is NOT easier to author, comment on, label, view history of, move without breaking links, etc. markdown docs vs Confluence. If I am the sole author plus my AI and the scope is narrow (a library), I go for MD. But for a big org, process docs, fast iteration… I’m not convinced, until someone builds equally powerful editing UI on top of MD files.

If you believe UBI can work, why do you think communism failed?

I’ve been dreaming about this for so long. Clearly I’m not the only one. While power delivery could be an issue, I’m surprised no tech company has come up with a real product.

It does remind me though of Portals from FB/Meta, which were really nifty, but not profitable enough for otherwise highly profitable company to continue investing in.

This is very well done actually, although I don’t think it can be a separate product compared to a chatgpt variant.

New comment by xixixao in "Y Combinator CEO Garry Tan launches dark-money group to influence CA politics"

xixixao — Wed, 11 Feb 2026 21:59:56 +0000

All reactions are taking this comment seriously, but I think it can be also read as "money equals power" (which I strongly believe - there's some power without money and sometimes money without power, but mostly those two are fungible) - and then pointing to the futility of getting money out of politics, since politics is about power.

But really what people mean is "prevent paid political advertisement of all kinds", which seems about as hard as "get rid of all kinds of advertisement" - at some point, you're back to power, communication, attention.

Hard problems. Probably there's a reason all ancient democracies did not survive.

I’ve been kinda obsessed with getting clothoids to work in a railway track editor. It’s easy enough to build out of clothoids into empty space, but connecting tracks is where it gets really hard.

For now all I have to share is this explainer I made some years ago: https://xixixao.github.io/euler-spiral-explanation/

2. I’m a big fan of the guy, except he went completely off the rails on political stuff… It’s hard that both can be true at the same time.

New comment by xixixao in "LLMs could be, but shouldn't be compilers"

xixixao — Fri, 06 Feb 2026 14:42:07 +0000

OP means “given the same input, produce the same output” determinism. This isn’t really much different from normal compilers, you might have a language spec, but at the end of the day the results are determined by the concrete compiler’s implementation.

But most LLM services on purpose introduce randomness, so you don’t get the same result for the same input you control as a user.

New comment by xixixao in "Finland looks to introduce Australia-style ban on social media"

xixixao — Sat, 31 Jan 2026 19:07:56 +0000

Your argument hinges on the assumption that porn and gore etc. have worse impact on kids. I don’t think there’s a concensus on that. One might argue that porn and gore could have been found in print before the internet, but that social media have a more novel impact.

I personally like the theory that most kids problems are actually attributable to family issues. That kids in solid family environment/upbringing will not be “destroyed” by computer games, porn, gore (2 girls 1 cup anyone?), or social media. But that’s also just a theory.

This is a classic false dichotomy. Vibe coding, automatic coding and coding is clearly on a spectrum. And I can employ all the shades during a single project.

I've built something very similar (also based on triangle meshes, but in TS), and while it wouldn't work for say 3D printing, my target is game object modeling. I guess people have specific use cases in mind when referring to "CAD".

Either drop the carousel or make it much, much more obvious that there's an animation going on.

Hmm, Rails, I wonder if the UI will work well.

I open https://railsui.com/components.

I click on the different components. They switch to a random component after a while.

My confidence in Rails for UI stays were it was :)
