I'd rather not go into detail, but in short they sent an official email from their real noreply address, "signed" by their CEO, saying my data has been compromised.

"What Data?"... Click the link...

Just kidding, April Fools you stupid moron.

I replied that they've lost a customer.

They replied with a link to talk to their AI bot.

How much is it React/Nue and how much is everything else?

HTML has evolved in the last 15 years to be a platform for applications. The early Bootstrap was a terrible Rube Goldberg machine because CSS didn't have civilized layout mechanisms such as grid and flexbox. Newer frameworks like Tailwind are more sensible, but still add 50k to your bundle, and if your app is complex and developed under deadlines you probably have components that use Tailwind and Bootstrap and emotion and styled-components and raw CSS and you still have to write some SCSS to get the styles just right in the end.

I've been investigating the accessibility of various <Modal> components and found that they all suck because they do complicated things with <Portal>(s) and various-aria-attributes. HTML has had a <dialog> component that properly hides the rest of the page since 2022 but barely anyone was using it.

If you stuck to using Tailwind or Bootstrap or raw CSS and used a minimal widget set you can make small applications with any framework. If you wrote raw CSS and made the most of the widgets that come in HTML5 (like the new stylable <select>) you can make tiny applications.

Yeah I mean - haven't we already been doing this a decade with home voice assistant speaker things and all found them to be underwhelming?

Theres 1-5 things any individual finds them useful for (timers/lights/music/etc) and then.. thats it.

99.9% of what I use a computer for its far faster to type/click/touch my phone/tablet/computer.

I read this in 1999 when entering university. It was so refreshing hearing a student provide a glimpse into the boots-on-the-ground reality of undergrad life at these world-renowned institution.

The closing sentence is also prescient; the author pivoted to CS, ultimately completing his doctorate at the University of Wisconsin at Madison

No, my case is predicated on it being bad to share information about an upcoming military operation with the Editor in Chief of The Atlantic and that doing so is the result is of a series of objectively illegal and incompetent actions.

The lack of investigation is an exemplar mechanism by which incompetence is allowed to rise to the top of regimes like this one.

There's no 5D chess. These people are just incompetent. Your gripes about the military-industrial complex are irrelevant.

Volvo sort of prides themselves on safety, including "smart" widgets.

2003 Blind Spot Information System (BLIS): BLIS uses cameras or radars to detect other cars approaching your car.

2008 City Safety: Emergency braking system using laser to detect, it helps reduce the risk of rear-end collisions at low speeds

2010 Pedestrian detection with full auto brake: Using radar and camera, this system warns the driver if somebody steps out in front of the car, and brakes by itself if the driver fails to do so.

2016 Connected safety: use the cloud to share critical data between vehicles, alerting the driver about slippery road sections or vehicles that have activated their hazard lights.

2018 Oncoming mitigation by braking: A Volvo car driving in a built-up highway with digitally rendered signs depicting oncoming mitigation by braking.

If an oncoming vehicle veers into your lane and a collision is unavoidable, this feature can help reduce your vehicle's speed to mitigate the force of the collision

2023 Lidar: Based on high-performance sensors, Lidar technology is key for creating safe autonomous cars. It helps autonomous cars detect other cars, pedestrians and cyclists

2023 Driver Understanding System: 2-camera system can detect if the driver is distracted, sleepy or even intoxicated. If needed, the system will activate a protective shield and take appropriate countermeasures to preserve safety margins.

Yes that just boggles my mind. Why is there a desire for such designs on a fundamental and safety-critical part of a vehicle? Aesthetic minimalism? But why?! A car door is not a phone screen. There’s plenty of real estate on a car door and it has no other function. It doesn’t need a hamburger menu. Just put a handle there, like we’ve been doing forever. Why does that need to be changed? A decision to hide the handles on a car makes me question and doubt every other design decision that went into the thing, because the designers have obviously lost their minds.

I evaluated a lot of Math Olympiads in Argentina. Humans participants many times don't have a clear sense of whether they solved a problem correctly. We get review request of the grades, sometimes it's a mistake but the grader, sometimes it's a tricky error that changes the result very little, sometimes the human participant made a chain of huge mistakes that make no sense. (Obviously, we give a polite reply in every case.)

Sure, it seems to be this Regent that wants to make "seaglider" a thing.

You can understand why they don't use "ekranoplan" as the marketing term. Its going to only be familiar to those who are into Soviet History, Aviation trivia or specific Sci-Fi.

And it's not going to bring small, modern, electric craft to mind.

It's honestly kind of bullshit because the bedrock of a lot of my work is being realistic, and if I had such a piece of crap equipment I would have gladly reported the 6.8 meters per second squared and then turned around and identified all of the problems with my setup right down to characterizing the lag time on the stopwatch start.

In fact one of the trickiest problems I had to resolve once was to show that the reason a piece of equipment couldn't accurately accumulate a volume from a very small flow was because of the fixed-point decimal place they chose. And part of how I did that was by optimizing a measurement device for the compliance of a fixed tube until I got really good, consistent results. Because I knew that those numbers were actually really good it came down to how we were doing math in the computer and then I just had to do an analysis of all of the accumulation and other math to determine what the accumulated error was. It turned out to be in really good agreement with what the device was doing.

All of that came from our initial recognition that the measured quantity was wrong for some reason.

> This will not primarily be for rescue ops

It seems like combat SAR in the maritime environment is what these are best at.

> The "Viceroy" craft that Regent has mocked up on their website claims 180 mile range, 3500lb of cargo / 2 crew + 12 passengers.

This is like 1/4th the size needed for minimum scale sustainment and support. Not to say that it won't be used for that in a pinch or for special operations, but it's pretty limited. Of course, there's been talk about building huge ones.

I think you're leaning a bit too hard on the wording here. If we're going randomly speculate based on tenuous reasoning like this, allow me to present the fact that such licensing regime does exist in China, so it's likely that Xiaomi did comply with it, rather than openly flouting the law.

It's primarily a reference to various language selection dropdowns offering "Chinese (Traditional)" (which is used in Taiwan) and "Chinese (Simplified)" (which is used on the Chinese mainland). That difference arises from Mao-era simplification of many of the most common hanzi characters to make them easier to write or distinguish.

Mixed with, yes, the variant spellings and word choices (e.g. chips/crisps/biscuits) that make it apparent to British English readers when something is American.

A spreadsheet is not very "community". And most definitely, demanding you to suddenly allow extreme surveillence against you, and to also own a smartphone, and to also install things on the smartphone and be physically able to do so as well, is most DEFINITELY not a "community". By this definition of talking to your immediate neighbors and knowing the whole neighborhood and whatnot.

That's never going to happen. Only a tiny fraction of the population live directly on lakeshores, and basically no warehouses. If drone based delivery is going to work then they'll have to fly out of ground effect to avoid structures and trees.

The main advantage of ground effect vehicles is lower fuel consumption over long distances. That's not a priority for the short range battery powered drones used by delivery services.

A couple of years ago I woke with a minor headache that I ignored for various reasons all day, then skipped lunch as I had an important meeting later and lots to do ahead of it, and the headache got progressively worse. Just before the meeting I felt nauseous, threw up, and then started having the feeling of palpitations in my chest. I've always had them from time to time - that feeling that ones heart has skipped a beat or taken a couple of extra ones - but this time it wasn't going away after a couple of beats.

To cut a long story short, I went to hospital (instead of that meeting) and it turned out that it was atrial fibrillation and that while it feels medium terrifying it's not necessarily that big a deal.

It went away after a couple of days (if it had lasted longer they'd have done "electroconversion" to try to get it back into the proper ryhythm artificially). Apparently the real danger of this is that it might cause a blood clot which in turn could cause a stroke, but it's unlikely to be an issue in the short term.

They did put me on blood thinners and beta blockers between the occurrence and getting a full check up a month later, so I was very calm when we rescheduled that meeting.

Top tip: don't ignore a terrible headache; go to bed.

Edit: PS I think my heart rate was just above 100bpm at rest (possibly 120?), which was unnerving enough, so I can imagine how much more scary 230bpm must feel! You definitely win.

Yeah, that's arrogance. I wish people were less simple-minded and throw everyone under a label; multiple times I've gotten the comment (irl) in the vein of "you actually know a lot about computers for an _apple user_". I always tell them that it's the reason I switched.

I'm not accusing you of being simple minded btw! It's just that most people are like that. Dumb people use windows. Dumb people use apple. Reality is more complex than "X = Y".

> Do they? The nature of the observable universe is that, if you can communicate with someone else, any information they can receive and pass on to you is part of your observable universe as all information travels at the speed of light or slower. If they can receive information and cannot pass it on to you, they are not part of your observable universe any longer and no longer exist (exception if FTL interactions are discovered). Thus the only observers that exist in a way you can interact with, can make any testable hypothesis concerning, and thus can be considered by science, are observers in your observable universe.

The observable universe is defined as natural light reaching us. It says nothing about repeaters. If someone id at the edge of your observable universe they could still send you a message. They’re observable universe would necessarily include light that wouldn’t reach you due to expansion. Of course, it is possible we’re within a black hole or some other weird space time geometry in which the universe folds in on itself in which case it is possible the observable universe is the universe. I’m not saying that’s impossible since we don’t know. I’m simply stating my Bayesian priors based on my understanding of the evidence collected so far about the CMB and what it and the theoretical models we have suggest. It doesn’t make other theories less valid, it just means where I’d make a wager if I had to. As you say, right now it’s not capable of being a scientific theory and it’s a stretch to even be called a hypothesis.

Still, this is just a reversion to our natural state where we have philosophical ideas grounded in the best knowledge we have trying to find ways to unlock the secrets, not unlike ancient Greeks. We might succeed or we might not but I still think it’s a scientific pursuit grounded in the scientific method in some way. For example, we have no way of really confirming whether our models are correct about estimating the distance to stars. Still, we think it’s true enough because it works locally. Science is and always has been a fuzzy endeavor of truth seeking and only local models of simple interactions have a “nonexistent” amount of error.

Coming from a .NET developer - why NOT F#?

* Network effect, or lack thereof. Very few people use it. * Its nature is contrary to the ecosystem. The CLR is fundamentally resistant to the paradigms that F# creates.

Wonderful little language - one of my favorites - and we owe a lot to it for the great features that C# has. But it just hasn't picked up the critical mass it needs.

I never went to driving school but isn't it obvious to both brake and steer away from the obstacle?

Not that long ago I had some idiot driving the wrong direction, in my lane, and speeding, and was about to have a head on at about 200 km/h. I credit my survival to pulling hard to the right while slamming on the brakes, with the ABS allowing me to steer freely. It put as much space between me and the idiot as possible.

My fancy new car has push to open doors and monitors the surroundings so it won't open if it detects a car or bicycle moving in the direction of the door. Could be handy.

But it's also designed reasonably. The lever you push to open can be pulled twice to open mechanically. There's no secret lever somewhere nobody knows about. Two different sales people told us to push or pull twice to open.

There’s a lot of negativity around this so I just thought I’d chip in and mention my appreciation for it. Projects are allowed to not be typescript, and I actively stay away from it as much as possible when working with browsers.

I don’t work in TypeScript, I don’t write in typescript, and I (along with everyone) don’t deploy typescript. I have multiple different build processes in my project to remove different types from different dependencies that are incompatible with one another just to untype them.

So personally I find standard js a huge selling point :)

The main 'Bletchley Park' exhibition is good, but it focuses on the human experience of the code breakers. Head around the corner from the car park to the National Museum of Computing (also on the Bletchley Park site) to see more technical exhibitions: they give proper demonstrations of the machines invented at Bletchley, as well as the oldest working computer in the world (which was computing prime numbers when I visited).

> Where does the LLM get their opinions on “foreign affairs” from?

Yeah that's a big problem with LLMs at the moment - people are having an argument online, and one of them posts a piece of text from an LLM and says "see, Grok/ChatGPT/Claude/Gemini agrees! You're wrong!", which only reveals how much they did not do their homework and that they're arguing on the basis of hear-say, just like the LLM; the LLM has no mind of its own. If 90% of the internet says A, it will defend A to the death. What's not part of the equation is how much of that 90% has the same source, financed by a certain group.

We have a LOT of work to do soon.

Also manufacturing a car is vastly different from manufacturing small electronic devices (not that that competence lives entirely with in Apple but they're experienced in designing them for manufacture). If Apple wanted to do car manufacturing that's a completely different area of expertise they'd need to spend a decade or more building up to.

Look at Tesla's journey, it took them years to get things like panel gaps even close to right on their cars and they're having massive problems with the Cybertruck's manufacturing (car washes can completely destroy their electronics, whole pieces of 'trim' falling off because they used the wrong glue, etc).

I think Nue just puts you in the mindset of trying to keep the codebase as small and lightweight as possible. I wanted to rebuild my website with Nue and there was something telling me to avoid Motion, Tailwind CSS, etc. This philosophy can actually prove very helpful in the long term, however I feel that by using Nue you're really compromising on DX (development is much slower), although that might be because I'm not so familiar with creating websites without a framework. In any case, it's definitely worth a try.
by shortrounddev2 | 2025-04-01 14:34:32+00:00
I like F#'s syntax when all you're doing is pure logic. But when you have to interface with any IO like a database or REST call or something, you have to abandon the elegance of ML syntax and use these ugly computation blocks. In C# you can do something like this:

var post = await _postService.getById(id);

in F# the equivalent is basically

let getPostById id = async { let! post = blogPostService.getPostById id return post } let post = getPostById 42 |> Async.RunSynchronously

But not really, because RunSynchronously isn't the same thing as `await`. Realistically if you wanted to handle the result of an async computation you would need to create continuations. F# isn't the only ML-family language to suffer from this; Ocaml does as well. It always seemed to me like the pattern with any asynchronous operations in F# is to either:

1. Do all logic in ML-syntax, then pass data into a computation block and handle I/O operations as the last part of your function, then return unit OR

2. Return a C#-style Task<> and handle all I/O in C#

Either way, ML-style languages don't seem like they're designed for the kind of commercial CRUD-style applications that 90% of us find ourselves paid to do.

> Also I assume radar-proof is just because it's a ground effect vehicle that will never fly high enough to show up on radar

My guess is yes. Simply because the Caspian Sea Monster [1] was "the largest and heaviest aircraft in the world from 1966 to 1988", not at all stealthy looking, and simultaneously also "undetectable to many radar systems, as it flew below the minimum altitude of detection."

So yes, a much smaller craft will also be hard to radar. Notwithstanding that the tech has moved on at both the "detect" and "don't be detected" ends of the contest.

As I understand it, it's also easier and safer to fly these craft now, as they are computer-stabilised, which the 1960s design could not have been. And therefore easier and safer to fly them lower. (The Caspian Sea Monster "was destroyed following a crash caused by pilot error." )

It didn't, actually. Instead go 1.15 has a static array of the first 256 positive integers, and when it needs to box one for an interface it gets a pointer into that array instead: https://go-review.googlesource.com/c/go/+/216401/4/src/runti...

This array is also used for single-byte strings (which previously had its own array): https://go-review.googlesource.com/c/go/+/221979/3/src/runti...

> Elixir

For me, it's Erlang. I just really like its horn clause syntax, it's so clean and readable. I know a common complaint is lack of piping (and even though you can implement it trivially, the order of arguments for some functions makes it of dubious use) but it's a small price to pay.

> I mean the language is really nice but the C# baggage and runtime was just a bit much

This was my experience with F#. Frankly, I've never been happy with my experience with CLI on Linux, and the toolchain inherits a lot of baggage from its C# heritage. Microsoft's toolchains have a very distinct workflow to them. F# has some interesting aspects to it like active patterns (something I wish was more common in the ML-family), but tbh I'm more than happy with ocaml.

Apple never clearly decided whether it was building a full car (like Tesla)? A self-driving system (like Waymo)? A tech stack to license (like Mobileye). This lack of focus created internal turmoil and killed momentum. The car team reportedly had over half a dozen leadership changes.

Apple lacked a tangible car ecosystem: no charging network, no manufacturing experience, and no clear place in the market for another premium EV.

The project was burning $1B+/year without ROI. Ultimately, it chose to cut losses. Apple failed because it was indecisive, risk-averse, and out of its industrial depth—while Tesla, Waymo, and Xiaomi had clarity, speed, and alignment between ambition and execution.

That’s pretty bad. On top of being unfair, it was a total missed opportunity to talk about the law of large numbers (I wonder if they could get a decent sample by combining everybody’s measurements) or skew (maybe everybody is a couple milliseconds too low just based on reaction time).

Or there could be some air resistance if you used, like, ping-pong balls.
Ask HN: Why hasn’t AMD made a viable CUDA alternative?
by spacebanana7 | 2025-04-01 14:37:54+00:00
I appreciate developing ROCm into something competitive with CUDA would require a lot of work, both internally within AMD and with external contributions to the relevant open source libraries.

However the amount of resources at stake is incredible. The delta between NVIDIA's value and AMD's is bigger than the annual GDP of Spain. Even if they needed to hire a few thousand engineers at a few million in comp each, it'd still be a good investment.
