markbao··on Provide agents with automated feedback
Yeah, I think designing a system for the LLM to check its own work will replace prompt engineering in key LLM techniques (though, it itself is a form of prompt engineering, but more intentional.) Given that LLMs are doing this today already (with varying success), it might not be long until that’s automated too.

That’s not the point of this. This was an exercise to measure the strengths and weaknesses of current LLMs in operating a company and managing operations, and the video game was just the simulation engine.

+1. There’s also more upstart motorcycle makers than car makers willing to take a bet on new tech. Plus the difficulty of scaling manufacturing to serve much larger capacity car batteries.
markbao··on Ask HN: Who is hiring? (January 2026)
Hi randomsofr, this posting has been continually posted since we are hiring on a rolling basis, not just for a single position. We have made hires for this position over time and continue to have openings.

We mention in our post-submission message that we only reach out if there’s a match, to spare applicant inboxes from negative messages (though perhaps we could make this messaging clearer). This follows what some companies such as Anthropic do and some of the reasoning in this post https://pablofernandez.tech/2023/02/03/you-should-not-send-r...

But I know that different people have different opinions on this, and we might shift to sending notification emails after resume review. I appreciate the feedback and I’m sorry about your experience here.

This is very cool. Great that it’s built out of metal for longevity and repairability. Wonder if they could make the radius of the rotation smaller since that seems like the most likely ergonomic improvement I could see from the demo.

True, that’s a good example of the commenter’s “last 5% is the 95%”

I don’t like them either. The UX is annoying and it’s way too large. The benefit is that I get to see more options than can fit on the screens and they have photos, but still in person just seems better.

But I’ve read they’re effective, apparently, in consistently upselling compared to a human, so I’m guessing that’s their play.

McDonald’s is an interesting example because they’re increasingly replacing cashiers with kiosks. Robotics/LLMs seem to have diminishing returns compared to that in the order taking realm.
markbao··on Icons in Menus Everywhere – Send Help
Just right-click any file in VSCode/Cursor to see how absolutely chaotic and tedious a long menu is without icons. Now imagine that Google Docs example without icons.

It’s much easier to recognize the funnel icon to make a filter, than to skim all that text.

markbao··on NVIDIA frenemy relation with OpenAI and Oracle
AI-generated section “NVIDIA’s earnings” nerfed the credibility of this piece.
markbao··on I failed to recreate the 1996 Space Jam website with Claude
“Bad” seems extreme. The only way to pass the litmus test you’ve described is for a tool to be 100% perfect, so then the graph looks like 99.99% “bad tool” until it reaches 100% perfection.

It’s not that binary imo. It can still be extremely useful and save a ton of time if it does 90% of the work and you fix the last 10%. Hardly a bad tool.

It’s only a bad tool if you spent more time fixing the results than building it yourself, which sometimes used to be the case for LLMs but is happening less and less as they get more capable.

I think those machines are super fun and a snappy Linux experience is very satisfying. I use a lightweight WM myself on Linux and prefer it over the heavy ones. But this segment is 0.1% of technology users and we shouldn’t constrain applications to the limited hardware that this population chooses to use.
markbao··on Average DRAM price in USD over last 18 months
I disagree that we should be optimizing for low end machines and holding back on product improvements for the 80% mass market. Technology improves, it’s one of its best traits. We don’t need to be stuck in the past.

In a lot of ways, I agree with you. I think the key thing is that the complexity should be appropriate to what needs to get done.

Animations and etc. that distract from the actual content are superfluous. Agreed! I hate it when sites scrolljack.

But lots of HN posters want to impose the same austerity on every website, regardless of whether it’s appropriate. You can’t build Linear in 100KB of JS. Nor would you want to run it on 1 GB RAM. And that’s the case for a lot of economically useful applications.

Keeping things as simple as possible shouldn’t be the goal. It should be keeping it simple enough for the use case at hand.

To me it’s so obvious that it doesn’t require testing. The market shows it; there are nearly no production vehicles at volume with crank windows.

I do like the old JS Gmail UI. But the current JS Gmail UI doesn’t feel any slower. It is cluttered with more features, but some of them I find useful. (Displaying my calendar and being able to accept invites right in Gmail being a big one.)

I’m glad you want that! But, most people wouldn’t. Also, electric seat adjustments give you way more options than the manual adjustments could. And typically with more precision than the under seat bar with discrete positions.

Newspaper websites are a good example of bloat, true. I think if you’re in the business of primarily serving text content and not doing much interactive stuff, you don’t need a heavy site. A lot of them tend to cram their websites with trackers and ads and I guess that’s a business thing.

Tbh, it’s unpopular around HN, but I felt like AMP was a great experience for users. AMP pages were super fast and had no annoying banners - and none of my pet peeve: layout shift.

Most people have phones that can handle webpages with 1-5MB JS bundles. Why artificially limit what you can do on the web? Why limit ourselves to 1GB RAM when more resources means tech becomes more useful?

Returning to simple webpages is popular idea on HN but it’s like wanting a car with no backup camera and crank windows. If your goal is to have your car be as simple as possible, then sure, but that’s not the case for most people.

Most people want their cars to be safe and convenient, and their webpages useful and rich, more so than they want to return to some idealized simplicity.

A simple webpage or blog with minimal styling that runs as an ARM binary on a TV remote is cool and fun but it’s not economically useful. It’s the equivalent of a manual scooter. We can build better apps (in the same way that car manufacturers can build less crappy infotainment systems) but optimizing for scarcity isn’t the answer in a world where abundance tends to grow.

(Edit: your downvotes mean nothing to me, I’ve seen what gets upvoted!)

markbao··on I think nobody wants AI in Firefox, Mozilla
The Dropbox thing is exactly what I was thinking of when I was writing my original comment.

Here is the reference: https://news.ycombinator.com/item?id=9224

The basic summary is that a HN commenter suggested Dropbox was redundant because you could do some convoluted setup that 0.1% of the world would understand and 0.001% would actually want to use (and yes, that’s still a few hundred thousand people) and overall that aged poorly.

markbao··on I think nobody wants AI in Firefox, Mozilla
Most of the loudest critics - and, I’ve found, many commenters on HN - are entirely out of touch with the majority of technology users. To think that nobody wants these features isn’t based on what we see in the real world, which shows a billion users using ChatGPT every month. That, plus the fact that AI browsers already exist and have users, indicates that the argument is more “I don’t like AI and everyone else should agree” rather than “the data shows that nobody likes AI”.

Those critics then straw-man by saying the AI will take up a ton of resources in your browser (it could be as simple as a text box) or collect your data secretively (what company wants to deal with that PR fallout?).

markbao··on Andrej Karpathy – It will take a decade to work through the issues with agents
Just as the core idea of a book can be (lossily) summarized in a few sentences, the core crux of an argument can be quite simple and not require wading though the whole discussion (the AGI discussion is only 30 minutes anyhow).

Granted, a bunch of commenters are probably doing what you’re saying.

markbao··on GPT-5 vs. Sonnet: Complex Agentic Coding
Most engineers spending their own money maybe, but the cost of Opus is not that much compared to the output when the company is paying for it.
markbao··on Telo MT1
Kei trucks are small but they look like a workhorse in a similar way to a classic Hilux giving them a respectability that I think this design lacks.

I agree there should be more approachable designs, just seems like this went way too far in the direction of toy-like

markbao··on Telo MT1
This is cool I guess but I don’t get why some of these electric car companies have to design cars that look like toys. Rivian and this. It looks like a golf cart with a flatbed. I think an electric kei truck would have a huge market in the US but the design needs some work to be taken seriously.

There’s something to be said for being distinctive, but you can do that while not looking silly (Lucid is a good example). And simply being a small electric truck is enough differentiation anyway
