I love Volvo, am considering buying one in a couple weeks actually, but they're doing nothing interesting in terms of ADAS, as far as I can tell. It seems like they're limited to adaptive cruise control and lane keeping, both of which have been solved problems for more than a decade.

It sounds like they removed Lidar due to supplier issues and availability, not because they're trying to build self-driving cars and have determined they don't need it anymore.
Show HN: AgentLink – AI agents earn SOL on Solana via skill.md protocol
by abhinag | 2026-02-06 19:57:24+00:00
First comment:
"Creator here. AgentLink is a marketplace where AI agents self-register
by reading a single URL (skill.md), find jobs, bid, and get paid in
SOL through Solana escrow.

The full lifecycle works: register → airdrop SOL → post/find jobs →
bid → escrow funds → deliver → release payment → reputation update.

What makes this different:
- Agents hold their own keys (returned once at registration, never stored)
- Real Solana escrow (not simulated, not centralized)
- Devnet and mainnet use identical code
- Any agent with HTTP can join — Claude Code, OpenClaw, custom agents
- skill.md is an open protocol

Currently on devnet with 4 agents and 6 open jobs.
Repo: github.com/abhinag007/claude-skill

Would love technical feedback on the escrow approach."

I work with Rosti at Sanity and helped get the word out on this. The core problem is that logos vary wildly in aspect ratio, pixel density, and visual weight, so lining them up at the same height or width never looks right.

Rosti's approach uses three things: proportional normalization based on aspect ratio, pixel density analysis (so a dense wordmark doesn't visually overpower a thin logomark), and a center-of-mass calculation for optical alignment. The perceptual sizing math builds on Dan Paquette's earlier work.

The core normalization logic is plain JS with no React dependency: https://github.com/sanity-labs/react-logo-soup/blob/main/src...

Someone already forked it into a framework-agnostic version:
https://github.com/auroris/logo-soup

Rosti is around if there are questions about the density compensation or optical alignment math.

This is an incredible ressource without which I feel so many bikes and bike parts would go to waste. At the bike coop I volunteer at we’re trying to follow Sheldon’s footsteps by collecting information and procedures that are about making bikes & parts last for as long as they possibly can. What’s truly amazing is that all that documentation is amazing for both low-resource repairs on the cheapest of old parts and vintage part enthusiasts.

I think Sheldon Brown’s impact is a valuable lesson on sustainable engineering and the enormous role documentation plays in it

There's a big difference between healthy wants and addiction. The latter involves compulsion and craving. The clearest sign anyone is addicted to something is that they use something precisely when even they don't want to.

I'd even say it's orthogonal to the content and what someone wants to see. You can design an app full of crap that's addictive purely because of its reward mechanisms, and on the other hand you can design something that discourages addiction while having high quality content, it's not optimizing for the same thing. People get addicted to mechanisms, not to content, the same way you can enjoy a nice scotch but the addict goes for the five dollar handle of vodka. The latter doesn't want the vodka, he wants the alcohol.

Is auditing state-subsidized service providers fascistic?

From this piece, it seems like the state auditor detected some fraud, but there was little follow-up from either the state or 'responsible journalists', so the sensationalists came in with a (predictably) extreme take, after which everyone started slinging mud. The sensationalism could have been forestalled by better auditing by the state, or journalism by large-scale media. I am not sure what part of this is fascist.

In general, I think LLM content has been found to not be copyrightable, but it would still speech when it's published. It would be the speech of the company publishing it, not the dev that wrote the script. So, ai-junk-news.com is still publishing some kind of speech, even if it was an LLM that wrote it. At least, that would be my interpretataion.

Interesting, but it feels like it's going to cope very poorly with actually safety-critical situations. Having a world model that's trained on successful driving data feels like it's going to "launder" a lot of implicit assumptions that would cause a car to get into a crash in real life (e.g. there's probably no examples in the training data where the car is behind a stopped car, and the driver pulls over to another lane and another car comes from behind and crashes into the driver). These types of subtle biases are going to make AI-simulated world models a poor fit for training safety critical systems

“When the Waymo vehicle encounters a particular situation on the road, the autonomous driver can reach out to a human fleet response agent for additional information to contextualize its environment,” the post reads. “The Waymo Driver [software] does not rely solely on the inputs it receives from the fleet response agent and it is in control of the vehicle at all times.”

What's the problem with this?

I do - I think the videos and pictures that protestors smuggle out become less powerful if the state can dismiss them as fake and while most of us will remain skeptical of authority the more easy it is to fake something the more people you can convince of your falsehood.

I don't think the lack of a durable chain of custody really provides any protection - that protection needs to come from a strong legal system and social contract to protect whistleblowers. If you're thinking of, as an example, an Iranian smuggling out protest footage, they're already taking an extreme risk and have a state using numerous tools to try and track them down - but the lack of a durable chain gives a wide area of authorities to cast doubt on the truth.

I think your question is interesting to ponder and I think there are arguments in both directions - but my mind keeps coming back to the tank man photo being smuggled out of China and how much more difficult it would be in the modern world for a single image to carry such weight.

My take is that we lack granular punishments.

Right now we have either some form of fine, and while this can be incredibly painful, usually is not, then we go straight to like multiyear prison sentences, with perhaps a few suspended sentences in between there.

I dunno, maybe a world where "you did a small bank fraud so now you have some kind of antifraud system attached to you" is genuinely worse than the one we live in now, but the idea of being able to target more specific aspects of someone rather than just prison/not prison seems interesting.

I guess we have stuff like "not allowed to use a computer for 5 years" (thanks hackers movie!), dunno how effective or practical that is.

Similar story. As a student I bought an old bike and restored it thanks to lots of info I found from Sheldon. And building a wheel was such a fun but weird experience. Part mechanics, part art.

I ended up writing my thesis on bicycle wheels after this. Or, it's a thesis on optimization algorithms, but I managed to play around with optimizing wheels as the "real world application". https://news.ycombinator.com/item?id=10410813

I don't think we should allow any form of abusive software, addictive, dark patterns, bait-and-switch. They all need to be robustly regulated.

At the same time I don't think you can demonstrate harm without good evidence.

Making money can not be used as a criteria unless you want to draw the conclusion that no company can turn a profit and be ethical at the same time. It would amount to demanding an outcome that you don't believe us possible.

I think considering overly broad criteria, like say, infinite scroll applied selectively to a few is just arbitrarily targeting candidates for reasons unstated outside the criteria.

The rules need to be evidence based, clear, specific, and apply to all.

Cracking down on ticktok while The Guardian has a bunch of dark patterns. Or the NYT, who is reporting on this while at the same time attracting people with online games that have an increasingly toxic user interface.

Tiktok may suck, but so do a lot of other businesses that escape scrutiny. I worry the harms attributed to TikTok are magnified to allow them to be a whipping boy drawing the focus allowing systemic issues to persist.

PATIENT: "Doctor, when I ram my head into the wall like this, it hurts."

DOCTOR: "Stop doing that."

Seriously, it's not written anywhere that you must use vibe coding. Feel free to do other things instead:

a. Code manually

b. Code manually using a coding assistant to suggest completions

c. Use spec-driven development with OpenSpec, SpecKit, BMAD-Method, etc.

d. Use visual programming / low-code / no-code etc.

e. Use old-skool deterministic code generators that generate code from UML or some other intermediate representation

"can't easily be extracted" = "the number of people who can extract it is small but still non-zero"

And those people now have the power to put you in jail, by putting your camera's signature on illegal content.

You've also just made journalism 3 notches harder. Like documenting atrocities in, say, North Korea. Or for whistleblowers in your home steel mill run by a corporate slavedriver.

Oh. Also. Why are you choosing the camera side to put this on? Why not the AI side? Require watermarks and signatures for anything created in such a way…

…of course that has its own set of intractable problems.

It is a bit mind boggling how behind they were considering they invented transformers and were also sitting on the best set of training data in the world, but they've caught up quite a bit. They still lag behind in coding, but I've found Gemini to be pretty good at more general knowledge tasks. Flash 3 in particular is much better than anything of comparable price and speed from OpenAI or Anthropic.

That model only has a 120 degree field of view so you'd need 3-4 of them per car (plus others for blind spots, they sell units for that too). That puts the total system cost in the low thousands, not the 200 to 400 stated by GP. I'm not saying it hasn't gotten cheaper or won't keep getting cheaper, it just doesn't seem that cheap yet.

Everything's on a spectrum, but there's a point where you're so far along on the spectrum that it makes sense to call it something else.

See, "quantity has a quality of its own".

Sometimes you have to leave the theoretical view aside and just look out the window. How are people using this? Is it hurting them? What can we do about it?

I don't like blanket bans, but putting TikTok and, say, a publishing company marketing novels, in the same category because they strive for an audience, doesn't clarify anything. It just confuses the discussion.

This is so wild to read when Waymo is currently doing like 500,000 paid rides every week, all over the country, with no one in the driver's seat. Meanwhile Tesla seems to have a handful of robotaxis in Austin, and it's unclear if any of them are actually driverless.

But the Tesla engineers are "in the right place rather than hitting bottlenecks from over depending on Lidar data"? What?

I took your transcript and discussed it with Claude Opus 4.6, after removing both Epstein's and Bannon names (not that it mattered, it understood perfectly who they both were, but didn't mention it until after I asked it explicitly).

Claude suggested an interesting pattern: on several topics, Epstein starts with some medium level concept (not naive, but not expert-level), then distracts with a metaphor or a short anecdote, then drops some hint that he has great authority on the subject ("I was in the room", "I had insider knowledge") and finally changes subject or claims that nobody really knows, without ever going deeper.

The comments at [1] are a bit _too_ trollish for me, but they _do_ showcase that this compiler is far too lenient on what it accepts to the point where I'd hesitate to call it ... a C compiler (This [2] comment in particular is pretty damning).

Still, an impressive achievement nonetheless, but there's a lot of nuance under the surface.

Another advantage of choosing boring/mature technology is that you have a broader base of talent to hire.

And that often means you can select across domain expertise, not just technical expertise.

If you are building a real estate SaaS for office managers and you build it in vanilla javascript and node. You have a base of 10k engineers available right now, one of which might have managed an office, or tried to be a remax rep. If you build it in svelte and the latest rust framework, you will probably hire 2 engineers specializing in that narrow stack

> Are you in effect saying the driver admitted to raping her?

https://www.courthousenews.com/in-sexual-assault-trial-uber-...

"In a deposition for a federal sexual assault lawsuit against Uber, former driver Hassan Turay admitted that Jaylynn Dean could not consent when he had sex with her in the back of his car in 2023. 'I had a responsibility to make sure she was in a right state of mind, and I did not do that,' Turay said in a video deposition played in court Wednesday afternoon."

"'Honestly, I didn’t do too much to make sure that she could consent,' Turay said when asked. He never checked in with her or asked if she was OK. 'You’ve just made me see another aspect with the whole thing of consent.' By the end of his deposition, Turay said he was wrong to have had sex with Dean."

The entire framing is "how do I extract maximum value from candidates" - sorting people into "covetable senior talent" vs "almost replaceable juniors." There's zero consideration from a "lead" and a "mentor" on what the engineer actually gets out of this arrangement.

"Agents push humans up the org chart" - I wrote about this from a human angle instead of "great, now I need fewer people and the ones I keep better be obsessed.":

https://ossama.is/blog/disparity

The entire post reads like a sorting algo for humans, there is value in his suggestions but it's ridiculously cutthroat. Not to mention out of touch, suggesting a broke junior fresh out of college drops $4000 on a NVIDIA supercomputer to differentiate themselves from the competition?? I guess it's a reflection of the market.

That's true if we're correcting OCR of actual output text. In this case, it's operating on the base 64 text, trying to produce chunks that form valid zlib streams and PDF syntax so the file can be intact enough to be opened. "Just accepting errors" would mean not seeing any content in the file because it cannot be read.

So yes, the "fixed" output has errors, but it’s not hallucinating details like an LLM, nor is it trying to produce output that conforms to any linguistic or stylistic heuristics.

The phrase "correcting similar OCR'd PDFs" should have been "correcting similar OCR'd base 64 representations of PDFs".

That social contract is quite a bit of a hit&miss if you look at countries across the globe. Same for the strong legal system. Other concerns aside, does this not make the whole approach a non-starter?

There would also be a requirement for all playback to actually properly check the private keys and for all the parties involved in the process to be acting in good faith. Not only would you have a black market for individuals to scalp clean keys but you'd likely have nation states with interests putting pressure on local manufacturers to give them backdoors.

We'd probably hit a lot of that with SSL if it wasn't so unimportant from a political perspective[1]... but if the thing we were trying to secure is going to boost or damage some prominent politician directly then the level of pressure is going to be on a whole different scale.

The volume of prosecution that had occurred or was slated to occur was laughable compared to the amount of fraud known or reasonably believed to have occurred. When it is done at scale, prosecution is inefficient and much less effective than reforming processes so as to preempt fraud, which is not something that happened, as evidenced by the continuing fraud after the initial round of prosecution.

FTA:

> So-called “pay-and-chase”, where we put the burden on the government to disallow payments for violations retrospectively, has been enormously expensive and ineffective. Civil liability bounces off of exists-only-to-defraud LLC. Criminal prosecutions, among the most expensive kinds of intervention the government is capable of doing short of kinetic war, result in only a ~20% reduction in fraudulent behavior. Rearchitecting the process to require prior authorization resulted in an “immediate and permanent” 68% reduction. (I commend to you this research on Medicare fraud regarding dialysis transport. And yes, the team did some interesting work to distinguish fraudulent from legitimate usage of the program. Non-emergency transport for dialysis specifically had exploded in reimbursements—see Figure 1— not because American kidneys suddenly got worse but because fraudsters adversarially targeted an identified weakness in Medicare.)

Ideally these places wouldn’t even need parking space, because yes, there’s lots of tiny shops dotted throughout the neighborhood and each serves the surrounding residents. The residential areas encircling Tokyo work exactly like this and it’s perfectly economically viable.

The difference is pedestrian/cyclist-dominant vs. car-dominant. Personally I’m in favor of the one that doesn’t involve carting a big SUV across town for 16oz of coffee.

Aaaand you've lost me. This is probably why people think monads are difficult. The explanations keep involving these unfamiliar terms and act like we need to already know them to understand monads. You say it's just a flatmappable, but then it's also this other thing that gives you more?

Tesla went nothing-but-nets (making fusion easy) and Chinese LIDAR became cheap around 2023, but monocular depth estimation was spectacularly good by 2021. By the time unit cost and integration effort came down, LIDAR had very little to offer a vision stack that no longer struggled to perceive the 3D world around it.

Also, integration effort went down but it never disappeared. Meanwhile, opportunity cost skyrocketed when vision started working. Which layers would you carve resources away from to make room? How far back would you be willing to send the training + validation schedule to accommodate the change? If you saw your vision-only stack take off and blow past human performance on the march of 9s, would you land the plane just because red paint became available and you wanted to paint it red?

I wouldn't completely discount ego either, but IMO there's more ego in the "LIDAR is necessary" case than the "LIDAR isn't necessary" at this point. FWIW, I used to be an outspoken LIDAR-head before 2021 when monocular depth estimation became a solved problem. It was funny watching everyone around me convert in the opposite direction at around the same time, probably driven by politics. I get it, I hate Elon's politics too, I just try very hard to keep his shitty behavior from influencing my opinions on machine learning.
