> This list could be much longer—most “experts”, in every industry, say some amount of bullshit

Gordon Ramsay is perhaps a perfect example of an entertainer that people mistake for an expert.

His job first and foremost is to entertain. That’s what he does.

Many people will jump to defend entertainer “experts” like this because they are actually good in their field and they share a lot of accurate advice. They’re making an effort to do the right thing and share the correct advice most of the time because doing anything too obviously bad too frequently would shatter the illusion.

But entertainment comes first. If it comes down to being pointedly correct and consistent versus being entertaining, they’ll choose the latter when they can get away with it. Praising a terrible grilled cheese is a perfect example.

This happens a lot in the workplace, too. Every company I’ve worked for has accumulated a few people who were very charismatic, loud, and entertaining, but everyone who knew the subject could see they didn’t know what they were doing. These people can persist for a remarkably long time, coasting on charisma alone. My clue that it’s time to leave a company is when those people start getting promoted and put in charge even after a year or two of consistent underperformance. Fortunately the better companies I’ve worked for have eventually caught on to the bullshitters and pushed them out, but it can take a painfully long time.

I mostly just use LLMs for autocomplete (not chat), but wouldn’t this be fixed by adding a “delete message” button/context option in LLM chat UIs?

If you delete the last message from the LLM (so now, you sent the last message), it would then generate a new response. (This would be particularly useful with high-temperature/more “randomly” configured LLMs.)

If you delete any other message, it just updates the LLM context for any future responses it sends (the real problem at hand, context cleanup).

I think seeing it work this way would also really help end users who think LLMs are “intelligent” to better understand that it’s just a big, complex autocomplete (and that’s still very useful).

Maybe this is standard already, or used in some LLM UI? If not, consider this comment as putting it in the public domain.

Now that I’m thinking about it, it seems like it might be practical to use “sub-contextual LLMs” to manage the context of your main LLM chat. Basically, if an LLM response in your chat/context is very long, you could ask the “sub-contextual LLM” to shorten/summarize that response, thus trimming down/cleaning the context for your overall conversation. (Also, more simply, an “edit message” button could do the same, just with you, the human, editing the context instead of an LLM…)

I already use Carplay as my de facto dash, as I trust the GPS Speedo in Waze more than the car and I shift on sound, not the tacho.

I won't buy or rent a new car without car play so this is a smart move. Hopefully the OEM customisation is on tight rails so they can't mess up the UX too much.
Show HN: Real-Time Gaussian Splatting
by markisus | 2025-05-15 13:26:49+00:00
LiveSplat is a system for turning RGBD camera streams into Gaussian splat scenes in real-time. The system works by passing all the RGBD frames into a feed forward neural net that outputs the current scene as Gaussian splats. These splats are then rendered in real-time. I've put together a demo video at the link above.

Because MySQL got a (rightfully so) bad rap before it adopted InnoDB as the default storage engine, and then tech influencers happened. I love Postgres, but I also love MySQL, and 99% of the time I see people gushing about Postgres, they aren’t using any features that MySQL doesn’t have.

The single biggest thing for MySQL that should be a huge attraction for devs without RDBMS administration experience is that MySQL, by and large, doesn’t need much care and feeding. You’re not going to get paged for txid wraparound because you didn’t know autovacuum wasn’t keeping up on your larger tables. Unfortunately, the Achilles heel of MySQL (technically InnoDB) is also its greatest strength: its clustering index. This is fantastic for range queries, IFF you design your schema to exploit it, and don’t use a non-k-sortable PK like UUIDv4. Need to grab every FooRecord for a given user? If your PK is (user_id, <some_other_id>) then congrats, they’re all physically colocated on the same DB pages, and the DB only has to walk the B+tree once from the root node, then it just follows a linked list.

Instead of an anthropocentric vision, you present here a "compucentric" vision, reminiscent of the works of Douglas Hofstadter, where the universe renders code, awareness reprograms, and everything is a recursive pattern. (This is Hacker News after all.)

The final authority in this story is then the universal computer (for lack of an operator or programmer of the computer) which executes this recursive function, creating these evolving forms of awareness and such.

The anthropocentric vision, in that we are the source of or own reality, is then for me instead much more believable, since the "compucentric" vision is after all thought up by a human without any evidence pointing toward the existence of such an universal computer.
Happy Birthday Brian Eno
by OhMeadhbh | 2025-05-15 13:27:12+00:00
Say what you will about his delightfully weird synth additions to Roxy Music or his elevation (if not invention) of the ambient genre, through his work producing other artists, Brian Eno has done more than anyone shape the sound of modern pop music, with the possible exception of Phil Spektor.

And through experimentation with new media has raised the bar with respect to the interplay between music, art and technology. Not to mention he just seems like a cool dude.

Happy birthday, Mr. Eno.

Ideally, this is the logical progression that balances automakers desire for having some level of influence on the experience, while still giving drivers the phone-driven CarPlay experience they prefer. Though if the balance isn't quite right, the automakers could gain "too much" control over it (and ruin it). It will be interesting to see what the real world experience is with it, though.

Android Automotive, pay attention. GM, I'm looking at you.

The main drawback is that RDEs need substantially stronger structure to smooth out the forces. It's still worth it, the force of the detonation (it's not separate explosions, it's a single continuous detonation front moving in a circular channel) is small enough to be containable.

There have been tests with multiple detonation fronts, but controlling them is much harder. It's very hard to have them go around the channel at exactly the same speed, so their positions relative to each other remain fixed.

To devils advocate my own point: the primary thing stopping you is people finding out and then stopping use of your product.

Zuckerberg doesn’t have a control panel where he can move sliders all by himself, any change in weight on the algorithm has to be implemented by a whole bunch of people, any of whom could leak to the press.

It’s not guaranteed it would happen by any means but it’s definitely something that would factor into a decision. Broadly I agree with you though, normally I’d say “extraordinary claims require extraordinary evidence” but I’m increasingly convinced the extraordinary claim here would be that they aren’t manipulating things to benefit themselves in some way or another.

The key problem, as I understand it, is that adding more guardrails makes the models stupid and less effective. AI models should just treat you like an adult and give you uncensored direct answers to whatever you ask. Figuring out how to make a bomb is trivial and anyone can find instructions with one quick internet search, especially after the war between Russia and Ukraine which caused a massive proliferation of tips and tricks on how to manufacture low cost bombs and other weapons. My memory is fuzzy but I swear I've also seen some declassified CIA documents which included instructions for how to manufacture weapons and engage in other forms of guerilla warfare.

The silliest form of "safety" is how most models won't allow generating erotica without jailbreaking.

Personally, I think the line might need to be drawn somewhere around "how to manufacture bioweapons". But it's also worth noting that any AI model that can figure out how to manufacture novel life-saving drugs will also have the capability to manufacture deadly bioweapons.

The thing about "it's just a marketing ploy" to me is that sometimes folk express astonishment and betrayal over that kinda thing. I don't quite follow that.

It's a private company that exists to make money, of course anything they announce publicly / is there to make them look good.

That's not bad, that's just understanding the nature of these organizations.

I'm a big fan of carplay, but I'm not sure I want whatever this is.

Some better integrations, sure. I can see wanting the carplay maps able to know the charge of the battery/fuel levels to plan out trips that include chargers/gas stations on the way.

But, taking over the entire dash? Nah, let's not overcomplicate things too much.
by neogodless | 2025-05-15 13:31:03+00:00
I don't think that's how these things work.

First, at least in the U.S., Apple iPhones are more popular than Android.

Second, there aren't "winners and losers". It's not anywhere near that black and white. And Android Automotive is... annoying when the automakers choose to block actual Android Auto and force you into only using apps that Android Automotive support, and in the case of GM, after 3 years you have to start paying a $40/month subscription to keep using apps. That's not winning in my book. A lot of people (at least on the internet) seem vocally opposed to the GM vehicles that do not support Android Auto.

If automakers are strictly only supporting Android and not iPhone, they will likely lose out on sales to the buyers who really prefer iPhone + CarPlay.

It is not just capital but the interpersonal and bureaucratic factors.

Technically the way to think about latency is that a process has N serial steps and you can (a) reduce N, (b) run some of those serial steps in parallel, and (c) speed up the steps.

For one thing, different aspects of the organization own the N steps. You might have one step that is difficult to improve because of organizational issues and then the excuses come in... Step 3 takes 2.0 sec, so why bother reducing Step 5 from 0.5 sec to 0.1 sec? On top of that we valorize "slow food" [1] have sayings like "all good things come to those who wait" and tend to think people are morally superior for waiting as opposed to "get you ass out of the line so we can serve other customers quickly" (e.g. truly empathetic, compassionate, etc.)

Maybe the ultimate expression of the American bad attitude is how you have to wait 20 minutes to board a plane because they have a complicated procedure with 9 priority levels and they have to pay somebody to explain that if you are a veteran you are in zone 3 and if you have this credit card from an another airline that this airline acquired you are in zone 5, etc... meanwhile they are paying the flight crew to wait, paying the ground crew to wait, etc. Southwest Airlines used to have a reasonable and optimized boarding scheme but they gave up on it, I guess the revenue from those credit cards is worth too much.

[1] it's a running gag when I go to a McDonalds in a distant city that it takes forever compared to, I dunno, Sweetgreens, even "fast" food isn't fast anymore. When I worked at a BK circa 1988, we cooked burgers ahead of time and stored them in a steam tray for up to ten minutes and then put condiments on them and put them in a box on a heat chute for up to another ten minutes. Whether you ordered a standard or customized burger you'd usually get it quickly, whereas burger restaurants today all cook the beef to order which just plain takes a while, longer than it takes to assemble a burrito at Chipotle.

I don't think it is, because the intro gets it wrong. If a problem's time or space complexity increases from O(n^2) to O(n^3) there's nothing necessarily novel about that, it's just... more.

Complicated on the other hand, involves the addition of one or more complicating factors beyond just "the problem is big". It's a qualitative thing, like maybe nobody has built adequate tools for the problem domain, or maybe you don't even know if the solution is possible until you've already invested quite a lot towards that solution. Or maybe you have to simultaneously put on this song and dance regarding story points and show continual progress even though you have not yet found a continuous path from where you are to your goal.

Climate change is both, doing your taxes is (typically) merely complex. As for complicated-but-not-complex, that's like realizing that you don't have your wallet after you've already ordered your food: qualitatively messy, quantitatively simple.

To put it differently, complicated is about the number of different domains you have to consider, complex is about--given some domain--how difficult the consideration in that domain are.

Perhaps the author's usage is common enough in certain audiences, but it's not consistent with how we discuss computational complexity. Which is a shame since they are talking about solving problems with computers.

I've been trying to learn how to cook with stainless steel without everything sticking all the time. My present understanding is to find the sweet spot between hot enough for the Leidenfrost effect to keep the food up off the surface while still below the smoke point of the oil you're using.

The temperature of the food you're dropping into the pan has a very real effect on this, and I've found that everything works better at room temp vs right out of the fridge because it reduces the amount of heat pulled from the pan in the first few seconds.

So, to your point, there are a lot of factors involved and some of them have nothing to do with the core temp of the meat.

Yes. Passkeys help with the bad password problem. That’s a big deal but doesn’t magically solve everything.

To address other security risks more comprehensively, you need to have a tight issuance process and use something key based in hardware. I’m working on a project where we deploy Yubi keys or similar, with an audit trial of which is used by who.

High trust environments need things like enterprise attestation and a solid issuance process to meet the control needs. Back in the day, the NIST standards required a chain of custody log of the token - you could only use in person delivery or registered mail to send them.

That’s overkill, but the point is the technology is only one part of the solution for these problems.

Why do you assume that the destination city is "even more expensive"? That should only be true half the time (for all pairs of cities, if one is more expensive, then the other must be less expensive).

I think it's more like this: Housing is super overinflated. Either I own or I rent.

If I rent, it may have taken me several local moves to find a situation that is a tolerable combination of price and quality. If I move to a different city, I lose that situation, and I lose all applicable knowledge of how to find another decent one. I have to start over at "low quality and overpriced", and improve my way from there, with several moves along the way. That's a hard psychological pill to swallow.

If I own, moving means paying 6% real estate commission. If housing is extremely expensive, that becomes a big number - though I don't know if that's the critical dynamic in peoples' minds. It may be the same as the renter issue - quality plus a decent price are hard to find.
by neogodless | 2025-05-15 13:32:55+00:00
You're conflating two things: displays... and controls.

Yes - all-touch controls suck. I know, I have a car that's mostly all-touch. It's so stupid. But the displays are lovely. As long as they don't take over UI in a car and replace physical controls for key functions that you control while driving, like climate, lights, wipers, volume.

That doesn’t make any sense. If philosophy contains bs it makes it so the whole field can be labeled as bs.

I understand there’s stuff like logic and the philosophy of science that make sense. But when there’s shit like animism it becomes a huge category error. why not just not make something like logic a part of philosophy? Just pull it out.

The umbrella of philosophy is like the category of analysis of everything in existence. It covers too much. It’s like anything that’s deep reflection automatically becomes philosophy. It’s too broad and that’s why it gets stupid when you have the philosophy of mathematics living side by side with the philosophy of art.

Interesting, we have a VW ID 3 and never have issues with CarPlay. The Skoda that we had before that (2016 or 2017) had a glitch every few weeks or so where it would hang. Though I guess the bugs hadn't been ironed out in the CarPlay support yet (that car did not have a net connection, so we never updated the software).
by echelon | 2025-05-15 13:34:51+00:00
> phone-driven CarPlay experience they prefer.

Oh god, no.

Not only is this awful, it gives the big tech companies huge leverage over the automakers. It's another industry where they'll embrace-extend-extinguish.

These companies will use smartphones as leverage to crush the automotive giants. It's another reason why we need antitrust enforcement to catch up with 30 years of being asleep at the wheel.

The automotive companies should be in charge of their industry and their destinies. Tech companies shouldn't be ensnaring them.

The phone giants already control how software is made and distributed (and they tax it 15-30%), insert themselves into digital payments and communications, place ads on your maps and navigation, etc. Soon they'll be taxing the car companies for integration, forcing the car companies to do what they want, and those car companies will pass that pain onto you, the consumer.

Bit of a nitpick on one of your subpoints (I agree with your sentiment overall);

GG won't/didn't fail due to the perception of "this person is filming me without my consent", that is a strawman meant to create more headlines than the less-sexy "it just doesn't have much purpose and is too expensive." Exactly like with VisionPro.

We're already under 1080p surveillance 90 percent of our waking lives out of the house. A person wearing glasses with a UI layer and a camera walking down the street likely isn't saving that picture, footage, to their home server to then send me a citation over. But the commercial businesses, police, DOT etc sure are, and are all subpoena-able by courts. Less so with a guy wearing glasses.

I mean... wasn't coinbase sort of scammy to begin with? Several years ago I gave them some USD, turned it into BTC, saw the value of the BTC go up, but when I tried to cash out was told that wasn't a thing that was supported by their platform. Later I was told I could apply for a $399/year credit card and could partially pay off the balance with BTC sale proceeds. I'm sure this was all disclosed somewhere in the terms of service I clicked through, and I only lost $1000 to their scheme.

But I've always wondered why people think this is how investment vehicles work. I monkeyed around with stock market bets and even Robin Hood allows you to cash out of your positions.

The argument is it’s infeasible. If user data in models is valuable corporations will move to legal regimes where it is allowed. Their models will get better and out compete the models made in regimes that do not allow it.

Governments (probably rightly) view ai technology as strategic so will build legal regimes that improve ai. This means that they will have power over the ones that don’t.

The last 50 years have shown pretty clearly that nuclear disarmament was a strategic mistake for regimes that did it so they won’t make the same mistake with ai.

I feel like the religious explanation is a copout (the rest of the details are in the spiritual realm lol) and maybe there are practical ones.

Like maybe coins are rare enough that they're not completely fungible, there is a slight preference for being able to know which one is which?

Say, people want to have affordances to trace the provenance if that starts to matter.

It could also be a legitimate aesthetic preference for currency units to be unique rather than uniform.

Maybe uniformity is hard but why make the dies much bigger than they need to be and use different parts?

Striking is downstream of casting, technologically because you need to make harder things and perform extra steps to do that.
