Open Pilot essentially created an aftermarket advanced adaptive cruise control that works better than most brands outside of Tesla. They just can't sell it legally as a whole package, so you buy the hardware, but the software is open source.

The difficulty of modifying the body, is mostly a financial decision I think. The body is by-and-large optimized for assembly rather than repair and modifications - that's why body shops charge an arm and a leg.

> Crumple zones are model specific you can’t just change those without making new car.

Yep, and I think that's the problem. Cars should be designed in a way that you can make this kind of safety upgrades. There's little technical reason why with a more modular body and platform, the manufacturer can't design a new crumple zone for retrofit, run finite element analysis, and crash test it.

They may need to rethink fundamentally how mass-market cars are made, like using more fasteners instead of welding in the body and frame, or using plastic instead of sheet metal when they are not necessary, like for the body panels.

That old malfunctioning airbags should be able to be replaced easily.

But then it would incentivize the customers to keep their old cars instead of buying new ones.

Well, they sort of do: they keep referring to the 4090, on their Github and primary promotional pages (https://wan.video/).

But really all the various video models really want an 80+ gig vram card, to run comfortably. The contortions the ComfyUI community goes through to get things running at a reasonable speed on the current, dinky-sized vram consumer cards, are impressive.

It could be that you didn't get real homeopathic medicine. There's been quite a few cases of babies dying after being given "homeopathic" medicine. Because real homeopathic medicine is indeed quack science, literally diluting a substance to the degree of one molecule per a sphere of water the size of the entire solar system, but homeopathic producers are grossly immoral and stupid/bad and unregulated, so can contain high, in some cases deadly, doses of various substances.

TLDR:

Homeopathic medicine is, in theory, 100% safe, since it's literally nothing.

Homeopathic medicine is, in theory, 100% ineffective, since it's literally nothing.

Homeopathic medicine is, in practice, rolling the dice with unregulated producers that have been known to ship poisons.

It'd be great to see Kubernetes make more extensive use of croups & especially nested croups, imo. The cpuset affinity should build into that layer nicely, imo. More broadly, Kubernetes' desire to schedule everything itself, to fit the workloads intelligent to insure successful running, feels like an anti-partern when the kernel has a much more aggressive way to let you trade off and define priorities and bound resources; it sucks having the ultra lo-fi kube take. I want the kernels "let it fail" version where nested cgroups get to fight it out according to their allocations.

Really enjoyed this amazing write up on how Kube does use cgroups. Seems like the QoS controls do give some top level cgroups, that pods then nest inside of. That's something. At least! https://martinheinz.dev/blog/91

There's lots of info about academic far leftism out there. This article is a decade old now (the problem is surely now far worse) but the trend in the graph is clear:

https://heterodoxacademy.org/blog/professors-moved-left-but-...

That's an average of self reported views, in a culture where everyone tells each other they're totally moderate and neutral. The problem is less serious in engineering subjects. In non-engineering subjects, far leftism is pretty much homogenous.

> It doesn't work that way, unfortunately

It works exactly that way.

> To get of fluid to behave that way on the scale of several inches, the fluid would have to be massive (very dense) while simultaneously gravity would have to be reduced.

No, it would just need to be very viscous. Viscosity is literally resistance to flowing, density is not, and a less dense fluid can nevertheless also be more viscous (honey is less dense than saltwater, but saltwater is much less viscous at STP [standard temperature and pressure, 0°C and 1atm], while mercury is significantly more dense than granite but something like 23 orders of magnitude less viscous at STP.)

This is a BMI-only study and should be treated carefully. They also found a protective effect for one of the obese categories, which seems extremely weird (unless you consider bodybuilders or strength athletes, in which case it would be reasonable). If you replace "don't be overweight/obese" with "don't have excess amounts of fat" (in particular vascular fat) it is certainly not a maybe.

This feels to me like a very naive statement, you don't just learn something magically because it permeates, it's because of experience and number of failures or actually really playing with a system.

If you are always on crutches and need the AI companion all the steps of the way, you basically offload the most important part of the work which is the whole cognitive work.

That "senior skill" is the debugging of complex systems that often interconnects in unusual ways, why? Because this might be a one off this might not be well documented, or even the code might not really point at the issue because it might be a subtle interplay of hardware and software.

Even if you are smart, it doesn't solve the problem that people still have to learn, and institutional knowledge is more important at times, because this might not be documented or easy to figure out, even with the greatest AI companion...

I can count multiple reasons why someone might dislike significant whitespace. The most evident is that whitespace is... not evident at all! By definition, it's a transparent character: it's extremely difficult to directly count spaces; they can be indirectly counted by comparison with text in the surrounding area. The same principle why we add commas or apostrophes or spaces every 3 digits in big numbers.

As of the "you're going to indent your code anyway" claim, this seems to completely ignore one-liners, either embedded in other documents (onClick=...) or fed to the shell as a quick way to get some work done without spawning new tools.

>Except even in volume, you've probably spent more than the car is worth (labor will be the killer, not hardware), or enough that the person whose economics dictate an older car can't afford the upgrade.

I'm not sure why that needs to be the case. Open Pilot is essentially a working aftermarket kit, but they can't sell the whole kit legally, only the hardware.

You have to remember these 1980s processors were ridiculously slow by modern standards, and "same type of results" implies a ballpark goal that was impressively aspirational on its own terms.

The details of "Does that mean the same speed, or faster?" weren't really relevant, because the speed difference was anywhere between 10X and 100X - which was an astounding, if rather fuzzy, target.

ARM 1 got surprisingly close to that out of the gate, with the added benefit of being unexpectedly power efficient.

Yeah, that was exactly my feeling too when I read that Airbus has "finally" caught up to Boeing. With that head start, catching up was not something that could have been expected (unless Boeing would have replaced the 737, which they arguably should have done years ago already, but that's a different story). Of course, if you look into the details, things get more complicated, since the 737 had an in-house narrowbody competitor with the 757 for some time - but Airbus now has the same, with the A220 competing with the smaller A320 family models (A318 and A319).

the problem with proportional representation is that nothing gets done, it's a permanent logjam with conflicting ideologies attempting to block or outdo each other.

Admittedly there is a bureaucratic logjam in the UK that hampers any progress but I don't see that going with fptp, I'd anticipate it getting much, much worse under prop-rep.

You may have a look at Quilt. I doesn't solve the problem the author described but may help you once you accept there is no easy solution in sight.

Quilt is automation for the "bag of patches" model. I used it once when I needed to upgrade the internal bag of patches at $big_corp so as to apply them to a newer version of $public_app. It was predictably complex but somehow still manageable.

If you squint a bit then the [bag of patches] + [automated application in order] is a poor man's Git. If you keep this in a git repo then you're basically versioning repos (poor man's ones) in a repo. It almost sounds like the solution to author's problem :)

Most juniors I watch program very quickly get overwhelmed by complexity because they dont know how to follow strategies like BDD or TDD which isolate parcels of complexity (e.g. how the program is supposed to behave) from other parcels (e.g. how the code actually works).

Even worse though, they all seem to think that the solution to becoming overwhelmed with complexity isnt to parcel it up with strategies like BDD and TDD but to just get better at stuffing more complexity into their brains.

To be honest, I see a similar attitude with LLMs where loads of people think you just need to stuff more into the context window and tweak the prompt and then it'll be reliable.

I have asthma, a few times I got an attack when I left my drugs at different home. Usually in such situation I have to go to a nightly doctor office (it always happens in the middle of the night on weekends).

But several times this happened I've been at my home and I have some old empty inhalers with 0 doses left and like 5 years past expiry date. I'm talking the disk inhaler, with discreet capsules of the drug that get used on every application - so if there were any traces of the drug substance - it would have been very small amounts that stuck to the inhaler walls or whatever.

I still used it and it stopped the asthma attack just as well as the real thing.

Placebo is one hell of a drug.

Similarly - even just preparing to go to the doctor in the middle of the night lessens the asthma attack for me. Just before I go to the doctor waiting in the queue the symptoms are often very minor.

"An interviewer once asked James Baldwin if he’d ever write something without a message. “No writer who ever lived,” Baldwin said, “could have written a line without a message.” This is true. People write because they have something to say. Baldwin had something to say, and he spent his life saying it. But many who thought they got his message didn’t get it at all....

That message was simple. We’re afraid of love, because we’re afraid of exposing our true selves. To manage that fear, we invent meaningless categories—Black, white, homosexual, heterosexual—and “other” the groups we don’t belong to in order to avoid a reckoning with ourselves."

I had to research what gymnasium meant, in the US that just means P.E. which is a class where you do generic sports for an hour each day.

Are you saying, in Germany, you can't choose to go academic route in primary/secondary school? The teachers and school decide if you will go into vocational school for mechanics, electrician, etc? That seems to imply class mobility is nearly zero in German education.

Common Crawl, while a massive dataset of the web does not represent the entirety of the web.

It’s smaller than Google’s index and Google does not represent the entirety of the web either.

For LLM training purposes this may or may not matter, since it does have a large amount of the web. It’s hard to prove scientifically whether the additional data would train a better model, because no one (afaik) not Google not common crawl not Facebook not Internet Archive have a copy that holds the entirety of the currently accessible web (let alone dead links). I’m often surprised using GoogleFu at how many pages I know exist even with famous authors that just don’t appear in googles index, common crawl or IA.

Slightly tangential: a lot of my vibe coding experiments are standalone SPAs because I can't be bothered to set up a secure server (and I am too cheap to pay for it). I love that I can open my "mobile-first" apps directly from my phone's Downloads folder.

I have a feeling that a lot of these little tools people make with low-code vibe AI apps do not require more than a single HTML page with JS imports.

(I also suspect that there is a ton of duplication in what people create, but, of course, I have no data to back it up.)

That is how many of the left talk about it. Some are more coy than others, but nonetheless that is the theme.

I certainly don't care for it and I certainly doesn't endear me to anyone making the argument.

So? The vast majority of the people in country had nothing to do with those events.

> the dumb and lazy way is to SSO through a government managed portal with OAUTH2

The weird thing is that UKGOV already has this for the NHS - my GP's app uses access.login.nhs.uk to log me in. That could easily verify my age to another system.

(Admittedly it's not sufficient for the wider case because not everyone is registered on nhs.uk but it does show that UKGOV has the capability to do this.)

Which is why democratic socialism exists, which has capitalism constrained by regulation as well as government participation in the economy.

Most industries require regulations, to maintain competition, to avoid market manipulation, to maintain public health and safety, and to stop crime.

Some industries require government intervention or even participation, to ensure the existence of nationally critical infrastructure and to protect national resilience and safety.

"Pure" capitalism is just as much a nonsense as "pure" communism.

First time I hear about him, but it looks like he is a scientist:

> Look at how he talks about the "10-20% flexibility". Hypothesis assumed true, no supporting evidence.

He started that part with "Here’s my perspective:", so for me it sounded more like his personal opinion/hypothesis, not a scientific consensus (and that hypothesis wasn't the topic of the article, so it's not strange for me that he gave no evidence for it there).

From my understanding, mostly based on Kerbal Space Program, the aircraft isn’t well balanced when equiped with modern engines.

So you have to constantly apply some controls to fly, done by software.

I love stupid car comparisons so imagine a car with a new engine that is more economical to run, but very heavy on the left so the car constantly want to turn left. But if you apply force to the steering wheel manually or the car does it for you with software, all good. Still a shit car though.

I can see the advantages RST offers in term of HTML generation, but whenever I've needed to work with custom blocks like that, I've always just written HTML.

I'm not sure if <img src="file.jpg" alt="alt text"/> is less readable than

.. image:: file.jpg :alt: Alt text

HTML5 allows for leaving certain tags unclosed (such as <li>, or <head> or even <p>) to such an extent that I find many template languages to not be worth the effort of their complex syntax.

Sure, there are three or four lines here that you can omit using RST or markdown:

<!doctype html> <html lang="en"> <head> <title>My blog page</title> <body> <h1>Welcome to my blog</h1> <p>This is a bunch of text. Feel free to stuff newlines here. <p>This is also a bunch of text <p>Here's a list just for fun: <ol> <li>This is the first item! <li>This is the second one! <li>Boom, a third! </ol> <p>Have an image: <img src="filename.jpg" alt="alt text goes here">

But is having to wrap a list in <ol> and closing the <title> really that bad?

Automatically generating an index and such is nice, but five lines of Javascript can do the same. Plus, you don't need to run a second tool to "process" your input.

I generally use Markdown as a standardised way to format text that will probably be read in plaintext by other people, but when it comes to formatting documents, I don't see the point of most complex template languages.

I think it's relative, really. The redundancy waves have a rhythm to them, and if you avoid one you're safe until the next. Contrast this to one of my previous experiences at a startup where I came in on Monday to discover there was no money, the CEO had been funnelling company funds to his boyfriend and once discovered the small office had turned to Lord of the Flies.

I wouldn't say I have the perfect job security, but I'm reasonably assured I'll get paid this month and I try not to worry about situations that haven't happened yet. I think if I had a family that depended entirely on me I'd be much more concerned.

I'm not sure I'd call it stockholm syndrome directly, but I'd agree it's definitely some form of conditioning.

I'm in a similar situation, having left a startup a year ago to work at $BIGCORP, naively thinking it would benefit my résumé. This is all painfully accurate.

The other thing about working for $BIGCORP is that it molds your skills to be hyper-specific to this company. It's less about learning to use cool technology stacks, than it is about learning the internal tools, procedures, and unspoken etiquette of the company. Skills that are vital to navigate the everyday complexity of $BIGCORP, but that you can't really export to any other job.

It has been kind of shocking to see Boeing's decline in real time like this. My whole life I saw them as an unshakable example of U.S. engineering superiority. Reading articles from current and former employees, it sounds like the decline actually began decades ago. It took this long to raid the coffers, so to speak, of talent, good will, and QA redundancy. It is suggested that they are too big to fail, but it will be expensive to re-pad all that redundancy, and I'm not sure subsequent leaders will be willing to lose the next decade of profit in pursuit of regaining their engineering credentials. I think the true cost of this has not yet been realised in their stock price.

I think what you're trying to accomplish is a factor here.

If you just want to saturate the bandwidth, to move some coherent blob of data from point A to point B as fast as possible (say you're implementing the `cp` command), then using large buffers is the best and easiest way. Small buffers confer no additional benefit other than driving more complicated designs, forcing io_uring with registered buffers and fds, etc.

If you want to maximize IOPS, then by the fact that we just established that large buffers saturate the bandwidth better, small buffers is the only viable option, but then you need to whittle down the per-read overhead, and end up with io_uring or even more specialized tools.

Happenned two days ago for me, the rule to block shorts from appearing in my feed caught a bit too much, and I mistakenly deactivated ublock while trying to refine them.

> There are elements of the 737 design that still exist on every new MAX coming off the line that would completely doom the certification chances of any new design, but are still there because they got grandfathered in for 737.

Not only that, but Boeing is actually limited in how much they can "modernize" the 737, because doing too much might exceed the limits of the 737's type certificate. This is the reason behind the current engine inlet overheating worries, which has led to an airworthiness directive for the 737 MAX (https://aerospacenews.com/faa-airworthiness-directive_boeing...) and is also one of the reasons for the delay certifying the MAX 7 and MAX 10. This would be a complete non-issue for other planes, because all modern designs have a switch position that only turns on the engine anti-ice system when it's needed, but the 737 MAX can't have that because the 1967 737 didn't.

In the late 90's, I administered the software test lab including UNIX workstations and Windows beige boxes I had build in addition to some servers, the LAN, and WAN for a nuclear engineering consultancy. There were a few Windows 95/98 boxes that were imaged for testing and contained 4 handy-dandy clones that could be copied (prior to widespread usage of Ghost). It would regularly stay running for a month at a time when disused, but I believed it was set to simply reboot to the first primary partition on BSOD. I bet at least one of event logs probably contained entries like these because centralized syslog/log shipping and monitoring weren't set up.

You're confusing too many things.

The Hessian is defined as the second order partial derivative of a scalar function. Therefore it will always give you a matrix.

What you're doing with the shape (m,n,n) isn't actually guaranteed at all since the output shape of an arbitrary function can be any tensor and you can apply the Hessian to each scalar value in the tensor to get another arbitrary tensor that has two dimensions more.

It's the Jacobian that is weird, since it is just a vector of gradients and therefore its partial derivative must also be a vector of Hessians.
