The properties of air that you care about are basically immutable, so why not pre-compute a bunch of compressed air instead of compressing it on the fly, and then having to carry the equipment to do that.

There is an energy cost to supercharging. While you get an overall horsepower boost, it's less than what it would be if the compression cost nothing.
I noticed the tank in the article's photo looks like carbon fiber wrapped aluminum. Those are noticeably lighter than the pure aluminum or steel tanks common in the 60's. (Source: Have carried each on my back as a volunteer firefighter)

This article gets the concept slightly wrong.The compressed air becomes very cold air when it expands rapidly in the intake.

Colder air is more dense and therefore carries more oxygen. More oxygen allows more fuel, which allows more power.

Here's a better explanation in a single paragraph on the company's website:

> The end result of these expansion processes is that the charge air temperature entering an engine is dramatically lower than can be achieved with conventional MAP increasing technologies (supercharging and/or turbocharging with after-cooling). Hence very high charge densities can be attained at relatively low MAP levels.

The goal is to increase the amount of air going into the engine by making it very cold and dense, not by pressurizing it like a supercharger. Low MAP means low manifold absolute pressure. In other words, it's not boost like a turbo or supercharger.

EDIT: It looks like the website is also unclear. There is some mention of a secondary valve shutting off the intake valve to prevent air leaking out from the air filter.

Their website is strangely unclear. This isn't mentioned in the "Theory of Operation" section but does get mentioned later as an "isolation valve"

People don’t use “understand” for machines in science because people may or may not believe in the sentience of machines. That would be a weird catering to panpsychism.

Surprisingly he makes a valid (completely theoretical) point. There is a way to Post hoc rationalize what Trump is doing.

The catch is in the end. There is no change in hell it works in practice. Neither politically nor strategically. Nobody trusts Trump to make anything than in-the-moment deals and the US can't inflict enough pain to the rest of the world to comply.

US Tariffs hurt the US most. Other countries can trade with each other without high tariffs.

It may be fair to say that it wants to work its way towards that as the industry matures, but that hasn't been the case. People have been able to make insane amounts of money in software. You cannot make money in a competitive industry.
C++ is very definitely not just wrappers around C and it's pretty ridiculous to frame it like that. Or if you want to insist on that, then C doesn't exist, either, as it's just a few small abstractions over assembly.
Show HN: nix-mcp-servers – MCP server Nix package repo
Started a collection of nix packages for some MCP servers I use. Makes installation into a NixOS-based system easy; also allows for running binaries straight from the flake on any Linux/macOS systems with nix installed. This can be convenient for MCP servers like `github-mcp-server` written in Go that aren't runnable using `uvx` or `npx`.

If it provides any comfort, Excel in turn is unable to properly open/save a CSV with the separator being a comma (!) unless the regional settings of Windows are not defining it as such.

On german systems it's for example a semicolon, so a CSV is basically a "semicolon separated value" file, and there is no working solution around that...
I imagine some of them do since it's seen as a 'convenience' for the reader who might upvote the comment (and the article itself, if it's something they're interested in). And yes I think it does have some kind of social element - people do it in other places and it drifts back into HN. There's a whole bunch of such folklore some of which gets naturally misapplied to HN, 'don't downvote for disagreement' probably being the most famous-while-inaccurate.

No you can't.

Even if you could (which you can't, at least on my, modern, phone), it would be a workaround, not a solution.

A solution would be allowing free selection like in the browser or, better yet, ditching "native" apps for web apps, as the person above suggested. As a bonus, this "exodus" will force browser makers to iron out any UX issues very quickly.
In most organizations the engineering manager would share that prioritization responsibility with a product manager who acts as the voice of the customer. One simple approach is to just divide team capacity into two buckets: 80% for new features and customer bug fixes, 20% for tech debt. The specific percentages can vary based on circumstances.

Third Grade Student Arrested by ICE Sparks Mass Protest
Personally I am almost certain that the current framing of RL and its relationship to animal behavior is deeply misguided. It proves close to impossible to train animals using this paradigm (not for a lack of trying), i.e. animals such as mice only make any progress when water deprived and under conditions that exploit their natural instincts. Nevertheless they are capable of far more complex natural behaviors. There is a non-zero chance that RL as an explanation of animal behavior is just plain wrong or not applicable.
> because car guys are absolute nerds.

Are they? At least in Europe they are usually blue collar guys that pick a neighborhood at random to hold a car meet, terrorizing that neighborhood until deep into the night, including street races. And if they aren't accommodated they'll aggressively clash with the police.

They're easy to spot too, pumped up douches with tribal tattoos and gemstone earrings that behave like they're prone to pick a bar fight with you.

In the Task Automation demo, how does it know all of the attributes of the motorcycle he is trying to sell? Is it relying on the underlying LLM's embedded knowledge?

Browser MCP uses the Chrome DevTools Protocol (CDP) to automate the browser so it currently only works for Chromium-based browsers.

Unfortunately, Firefox doesn't expose WebDriver BiDi (the standardized version of CDP) to browser extensions AFAIK (someone please correct me if I'm mistaken!), so I don't think I can support it even if I tried.

> why should we romanticize and pine for an era that has been passed by? Why shouldn't we have a vision for a new era and double down on the things we are best at?

Because if something bad happens, be it a war, trade war with tarrifs or a pandemic, or just a stuck ship somewhere blocking transport, you're left without everything that you were once able to make, but can't make anymore.
Encouraging the continued anthropomorphization of these models is a bad idea, especially in the context of discussing their capabilities.

Not a sign I ever expected to see. I heartily endorse the sentiment, though.
Nitrous oxide is the safer equivalent, relatively speaking. Pure O2 would make things burn that normally don't burn, and increase engine detonation.
This is really well done! Very cool.

I wonder if it's possible to add such plugins to election apps (e.g.: Slack).
It would be such a nice experience if I could just connect my AI of choice to a local app.
Services, in my mind, is a broader thing than just market exports (which I agree are largely tech). Consider the pejorative term "nanny state." The government bureaucrat testing your water for lead is part of this system. Bessent is very explicitly saying that the administration is deliberately shredding jobs in the federal bureaucracy and expects those people to go work in the factories they hope will be created based on these policies.

While there's definitely an "ugh, not everything has to be about gender studies" reaction to some of these ideas I personally can't stop seeing it over and over and over in the new administration and social reaction to it. Zuckerburg saying that we need more "masculine energy" in tech and rebranding his image. Mel Gibson saying that Trump is "daddy" returning home and taking off his belt to beat us back into shape. Vance and Musk's obsessions with childless women.
No, since MCP is just an interface layer it is to AI what REST API is to DPA and COM/App DLLs are to RPA.

I'm back at +1. HN has a small enough population that one or two votes can't really be taken to mean anything.

I would not be surprised if there is a general resistance to this sort of framing among some HN readers, but I'm not going to take snap decisions of one or two people to mean much.
Drag racing has none of that.

What is it the kids say? "Tell me you know nothing about drag racing without saying you know nothing about drag racing"? Drag racing has all of that, squeezed into 1/4 of a mile. That's why top fuelers get an engine rebuild after every trip down the track.

It's like saying, "I get ultramarathons, but 400m foot races involved little skill or training." Look, if you don't get it, fine. Probably best to just leave it at that.

> This amount of revenue/profit will cause a company of 500 or 1000 to go bankrupt

tinfoil hat question: who wants computers to turn on overnight or every day?

Isn’t it exactly what alphazero did?

“AlphaZero was trained solely via self-play using 5,000 first-generation TPUs to generate the games and 64 second-generation TPUs to train the neural networks, all in parallel, with no access to opening books or endgame tables. After four hours of training, DeepMind estimated AlphaZero was playing chess at a higher Elo rating than Stockfish 8; after nine hours of training, the algorithm defeated Stockfish 8 in a time-controlled 100-game tournament (28 wins, 0 losses, and 72 draws).” [emphasis added] https://en.wikipedia.org/wiki/AlphaZero

The book I consistently reread is Notes from the Underground. Anything by Balzac is highly rereadable also. I don't read much fiction anymore but fiction has left the deepest imprints on me. I did just read Jew Sus by Feuchtwanger, I'd recommend it. All of Kafka's works are up there too.

I just view it as a relative minor convenience, but it's not some game-changer IMO.

The tool use / function calling thing far predates Anthropic releasing the MCP specification and it really wasn't that onerous to do before either. You could provide a json schema spec and tell the model to generate compliant json to pass to the API in question. MCP doesn't inherently solve any of the problems that come up in that sort of workflow, but it does provide an idiomatic approach for it (so there's a non-zero value there, but not much).
Maybe for many people the democrats were worse and they are happy things are back to what they consider normal.

> unions are the best way

They are when labor is fungible, and when you're not paid by the public. Lots of crazy effects happen when the second condition is not met, for example prison guards unions advocating for harsher laws so that prisons stay full.

> That doesn't mean printing money

In principle, it does not. In practice you can count the countries that don't deficit finance on one hand.
It _could_ be that, too, but as it turns out, in this particular case, it was the scary scary transes (see their response elsewhere in the thread).

With people who go on about 'luxury beliefs', the belief that they're referring to is nearly always 'trans people are people', I assume because it's such a new coinage (it's only a few years old) and that was what the far-right were mostly scared of at the time.
I am mostly imagining the "happy middle" scenario where you raise $1m and sell for $10m in cash, but modified to assume you raised $10m and spent $2m of it, and then got the $10m in cash from the acquirer, and still have $8m in the bank account, you would give back $10m to your investors per the liquidation preferences and then split the remaining $8m.

You are in a worse boat than if you had only raised the $1m and then sold for $10m, but the founders probably still walk away with ~5-7m pre-tax (depending on how much equity the $10m cost you over 1-2 rounds), and you're in a better position than if you had run through the $1m and hadn't quite gotten to a thing worth $10m.

The engines still get destroyed. It's basically a complete rebuild between runs. Most of the spark plugs burn up, clutch disks get welded together, etc. The goal is basically to just not have the engine outright detonate so they can reuse the block.
Reminds me of this piece of motorsports history: https://fordauthority.com/2017/12/how-ford-cheated-the-rules...

Take, for instance, Ford’s car from the 2003 FIA World Rally Championship. Through a knowledgeable automotive tuner and journalist named Stav from the UK (Facebook page), we learned that the 2003 Ford Focus RS WRC used an ingenious, mostly-hidden system to store excess pressurized air from the turbocharger in a titanium tank until it could be advantageously crammed into the engine on straight portions of the course, elevating power beyond what would otherwise have been possible.
