Ask HN: What prevents the automotive industry from using safe LEDs?
A lot of you had something to comment about in that submission about Ford’s new electric pickup [0].

All I noticed were pictures on Ford’s website demonstrating terrible headlights. Not all automotive LEDs are terrible, just the ones that emit too much blue light.

Kia has a few models with orange LED running lights. But it seems most new vehicles are designed to blind everyone.

Blue LEDs are great for plants. When used as a balanced portion of a white light they’re fine.

Science knows about the hazards of blue light. Decades ago, scientists studying human response to light figured out that humans do best in low light environments with lights that are red, orange, yellow. This is why our streetlights used to be orange, until the LED companies stole the old light companies’ business without realizing there was a reason behind outdoor lights’ usual spectrum. Or they did know but couldn’t compete with their products, so they pretend their products’ terrible spectrum doesn’t matter.

I think I’ve encountered most the mistakes behind the automotive industry’s switch to defective blue-white LEDs instead of safe orange-biased LEDs.

But before I put my thoughts out there, what are your theories for the mass proliferation of blue-white LEDs in low light environments?

BTW Germany is still paying compensation to the churches for expropriation under Napoleon, and that was also some time ago.

Just FYI, it's "carrier-grade NAT". And there are a lot of ways to associate people with each other other than their public IP address. The linked twitter thread doesn't even mention IP addresses, neither does the comment you responded to. I suspect IP addresses are already a pretty inaccurate way to link people with each other.
Sorry I didn't make myself clear. I was surprised because two databases from Alibaba are open sourced or to be open sourced.
That's freedom of expression.
Agree with you on both. Rare I think. And those who share it are becoming more and more afraid to express them.

One of my first forays into this was a proper blowtorch vs a normal kitchen torch.

My recipes requires adjusting, but once I fixed them up, they were great.
Doesn't mean I have to respect for be sympathetic to it. It is just organized stupidity at scale.

That said, it's hard not to play the game and buy in. I just write my vanilla Java, say right-sounding things in meetings, and somehow get Paid despite barely doing a thing.

Corporate software development is a great career tbh - instead of paying me to use Kleisli arrows for the company's gain, the company effectively pays me to use Kleisli arrows on my own IP lmao. Gotta love all that frothy waste that's produced by Worse is Better. Waste that the average dev can now reap thanks to the boom in remote work!
Kirkland Signature is reliably great, especially in comparison with other store brands. I’m a bit of a Costco fanboy though, in full transparency.

My partner and I used to argue over who gets to make the monthly Costco run but now we just make it into a big family outing (Friday evenings are an amazing time to shop there).
Looks like it is. Fooled by the artist’s rendering. Again.

Anyone have a shot of the actual decking on this pool? They must have hidden expansion plates in the design to allow the bearings to work without eating human legs.
I went to NewEgg (in the U.S.) for electronics item orders but some of the complaints about electronics, like expensive Nvidia cards going missing or whatnot, I've seen complaints for with NewEgg. Third party shippers, quality control issues are rife in reviews. In fact I ordered almost 3K of computer equipment from NewEgg that got stolen on my stoop as USPS threw it on a sidewalk in a giant city here, which was promptly stolen by a miscreant. NewEgg made me go to the police a couple of times but they did issue a replacement. So it's a mixed bag - they should have forced signature required.

NewEgg > Amazon for computer equipment but the jury seems out. Any other alternatives for expensive PC parts?
The advertising sector has adapted: On Reddit, Twitter and plenty of other social media, a whole lot of content is ads but veiled as memes.
Ads are a pretty good proxy for how much profit a sale is. While a car is a high $ purchase, moving your $40/month cellular plan from one provider to another is $thousands of profit loss for one provider and $thousands profit for another.

Sometimes fixing the problem will require special access to Production which you don't have, or even a specific role with that extra bit of initiative.

Otherwise i agree 100%.
I agree with having empathy for future devs, but I think it only goes so far. I've often seen junior engineers unable to differentiate between code they don't understand and bad code.

Usually they end up thinking they can do a better job, decide to rewrite the thing from scratch, and take 10x longer to rewrite it than they thought it would take. And accomplish nothing in the end, because the thing they rewrote worked in the first place.
The damage is one had a deal to pay X for a roof. If they can't fulfill their end of the deal, the damage is the difference between X and what have to be paid to get what was promised (either from them or a different provider).

It's bad that they're trying to track you in any way.
It likely doesn’t for IPv4 now that everyone has switched to HTTPS.

Many ISPs used to insert “client id” and other uniquely identifying information while NATting/proxying. Luckily, they can’t do that for https - but I wouldn’t put it beyond them to sell a back channel “connection xyz is unique user abc” service.

However, with the move to IPv6 , at least in my area, NAT is gone and static assignment is in. You just need to know the isp’s prefix length, and you get a unique identifier.
>But from the point of view of everyone else, maybe it is fine

I think from a practical perspective, it is fine. You want results and you have a black box algorithm that produces them, fine.

From an academic perspective, AI research is a mess. The reason you try something is not from a logical theory, but due from a "hunch" or replicatinga similar algorithm applied in a parallel area. If it does not work, you change some parameters and run it more times. Still not working so maybe you extend the network to include some more inputs and hope for better results.

I did my thesis in machine learning and was very disappointed with the state of the field.

Funny sidebar related to a top post yesterday about topical engagement on Twitter, the author of the tweet describes his feed as follows:

> If you like D&D consider sticking around, my account is 85% tabletop RPG development and 15% leftist politics.

Kudos to the author for taking his audience what they should expect after following. But isn’t this a really narrow audience? Why not have 2 accounts: robertgreeveathome and robertgreeveatwork so I can pick which content I’m interested in?
I appreciate the link and summary for McMaster-Carr[1].

It is so pleasing to use this site and it is simultaneously full of utility as they stock a wide array of fixtures and hardware that are difficult to search for elsewhere.

The user interface is a wonder. It's too good to be true. In fact, using the UI actually saddens me because you know some kid who thinks they are a design genius is going to get hired there and "improve things". It's almost a physical law.

The evidence is in the linked NY Times article, in the section titled "Price Control." They also cite a paywalled Bloomberg article.

Yes, and one day we will have biological "cars" that can behave autonomously, avoid collisions, climb hills, cross shallow rivers, pull storage carts behind them, operate on simple grass consumption, be used in battle, and generate new cars through a cheap replication process. The technology of the future will be insane.
Maybe you can help me understand the context better. From the GP post where he seems to advocate for separate male and female labs he seems to imply there isn’t enough professionalism present to have co-ed labs.

I’m saying that claim is more an implication of the person saying it and their (lack of) professional ethics than an indictment of the subordinates. It’s very similar in my mind to the recent arguments about gender in military units
A friend visited me from Ohio (I live in New Hampshire). After hanging out for a few days, I was getting twitter ads for local Ohio stuff.
I disagree strongly with it on multiple fronts. That concern should be secondary to your program actually doing its job well. Your customer will literally not care how elegant or ugly your code is; they just see the end result. And when the program fails them, it really doesn't matter to them whether your juniors understand the code or the error. Moreover, not every abstraction is (or can be expected to be) accessible to an entry level engineer. Some technologies just take a long time to master, and doing that can also require higher-level abstractions.

So I would say great code is code that:

1. Does its job well (robustly, performantly, etc. in whatever proportion is applicable)

2. Is maintainable by engineers with reasonable expertise in the tooling

in that order. If you can manage all that and make it accessible to your junior devs, that will of course make your code greater. But don't lose sight of what your customers care about. Your business isn't there to make you feel good about maintaining code, it's to provide customers with value.
I know you probably didn’t mean it but I still want to state it. Your personal simplification of life or the amount you personally care or not doesn’t define monopolistic behavior. The entire population may not care about something but it could be disallowed.
> but that there is a need for more clinical trials, which is an enormous difference.

Almost twenty years after this compound was developed into toothpaste, the best we can show in peer reviewed research is “inconclusive” when it’s used in toothpaste and you consider that a big win? I consider that “doesn’t seem to make much of a difference”.

Maybe it’s the novamin that helped you. Maybe it is one of the other compounds. Regular Sensodyne is a toothpaste for sensitive teeth, after all. Maybe you just started brushing more carefully. I did when I got my pack of “Sensodyne whitening repair & protect deep repair” toothpaste. That tube was almost double a regular Sensodyne, which is already an expensive brand.
Those who don’t like what Amazon is doing have many other choices. The correct “oversight and regulation” is customers migrating to those who offer better, not financially disinterested third parties compelling financial consequences without consent.
Not really, no. Human nature is what we're dealt, we must embrace both the positive and negative aspects of it. Perhaps the inevitability of two people gravitating towards one another can be leveraged? Perhaps the disparities can elucidate us on unseen proclivities in different populations, things that can also be leveraged and positively.

What we should avoid is cramming people into functionary roles and instruct them they must act as would a machine. No longer can they be compelling or compelled but only impelled as would be a gear turning in the insurmountable forces of the engine that drives.

Heuristics. Marketers do cross-device correlation only when seeing a small number of devices (ie. look like they could be part of the same household). If they see hundreds of devices behind the same IP it's probably a larger entity (ie. a company office).
Don't forget, a VPN, a new email account and a new phone number for "2fa". Also, where is it getting shipped? I can't receive packages at work. The "convenience" of shopping online is a legend from my youth
So you want to restrict people from getting a phd unless they can get a top job out of it? What about people who want to do research but aren't worth the pay/responsibility of top jobs? Is your goal to increase the value of a phd by limiting it to highest quality people possible (like with MD's)?

Tenure is a benefit that is given instead of money to keep you from leaving for more money. It may be nice to have late in your career if you want to keep working forever or bizarrely want to stay at your research-focused school but focus on teaching. But money adds up nicely and has more flexibility. And like with job offers and promotions everywhere, it's something you generally can only get if they need you more than you need them.
Yes absolutely, even if ive slept 9PM to 630AM, something about the early morning makes my neck and stomach burn and my eyes hurt. Strange!
I think you're extending too much credit to many of these sites, who purposefully sequence a shipping estimate after four screens (to boost perceived sunk costs and committment) and after requiring your email address (so they can spam you in the future).

This just gave me an idea. We could build houses that are returned to the state when we die. In return there's no property tax, no sales tax, no tax on repairs to the house during your lifetime.

That way people could afford a home that is theirs until they (and their spouse) die.

LoRA isn’t a “proprietary” standard. It’s open to everyone to use. It operates at 900 mMHz, though, so the point is that your average WiFi or Bluetooth device can’t transmit or receive it. That 900 MHz spectrum is unlicensed, so buy a dev kit from Adafruit and go make some RF noise!
There's a difference between choosing higher taxes and tolerating higher taxes. Further, voting with one's feet is easier said than done - the overwhelming majority of people can't arbitrarily move wherever they like whenever they like.

Ultimately, all attempts at attribution are heuristic in nature. Marketers know a single IP doesn't represent a single person, but if it's the best they can do, it's the best they can do. Even for services with accounts, tracking can't be perfect. When my wife's phone or laptop is closer than mine and she's logged into Amazon Prime or Uber Eats, I'm ordering through her account. Now she's gonna see ads for gym equipment she has no interest in. Oh well. It doesn't matter how good your location, device, browser fingerprinting is when people share locations, devices, and browsers. The only way to know it's really me is to get my actual fingerprint or some other truly unique biometric identifier.

Exactly.

How many entry level engineers come onto a project per year? 5? Is onboarding them onto the project is a deliberate and streamlined way such an undue burden that you must change your programming style to avoid it?
You might want to look at Simplex to describe better and more rigorously. Simplex is the most basic structure to describe a space in n-dimension.

0-simplex: a point.

1-simplex: a segment (points and lines)

2-simplex: a rectangle (points, lines, and surfaces)

3-simplex: a tedrahedron (points, lines, surface and a 3D space that most of human can comprehend visually)

4-simplex: everything above and the whole combination of these element in algebra.

This is how mathematician and physicists solve problems. Time is a separate element in our equations that why we often talk space-time, not just space

https://en.wikipedia.org/wiki/Simplex
This is a nice paper. A couple thoughts that I haven’t seen raised yet in the thread:

1) this paper exhibits, for the first time, a continuous family of warp drives which contains Minkowski space (see the end of S.4.3). This means that it is, in principle, possible to turn on/off a warp drive, which is a basic requirement if you ever want to build one.

The next basic feature we need to understand is how/whether warp shells can accelerate/decelerate. No paper in the literature does this yet, afaict. Would be very exciting if Bobrick and Martire can exhibit this in a sequel!

Proper Signal Handling in Swift
Hmm, am I writing posts in my sleep?
Disclaimer, I'm a CTO.

Here's how I evaluate this if I was evaluating you:

1. I already have a salary budget already allocated for this role based on industry average for position and location (but location _could_ be irrelevant depending on skill mostly).

2. I look at your skillset and put you at the bucket for the position where you are at: low-med-high

3. I make my offer based on my evaluation.

4. If you are "worth it", meaning in the high bucket, then I would go out of my way to give you a good offer, up to max of my budget or to match how much you are asking. Else, I would say the offer is where it stands and either you take it or don't.

But to answer your question, it doesn't hurt to push back as long as you are confident in your skills and know your value is worth more. That one you have to make up for yourself by evaluating yourself with peers and other factors.

Oh. And if you do push back, make sure to give a good reason why it is so. For example, if I happened to put you in the low bucket, I might have evaluated you wrong or the tests did not show much of your skill, then make sure to outline why you deserve that salary increase with good reason. As a quick example, if the industry average in where you are is $50,000 and you are offered $30,000 which is the starting for a junior, you can say that you've been developing for awhile with at least 5 years experience and that $50,000 would be a fair salary etc etc.
Teslas made in Texas will likely have to leave state before Texans can buy them
Yet very often they charge restocking fees which is unheard of here. And also these policies are up to their discretion. As you can see in e.g. Walmart’s policy they reserve the right to decline the refund. Better to have a guarantee by having it in the law. Again as stated before, Amazon is known to shut down accounts for returning too often.

> he says that children will be educated "on a communal basis" and will not be dependent upon their parent

In modern mixed economies (which while themselves quite far from the Marx’s ideals are arguably closer to it than the Leninist-derived “Communist” systems that pay lip service to Marxism), it is very common, compared to the capitalist system Marx critiqued, to have particularly strong social support networks targeting children (even the US, with its generally weak, among modern developed systems, safety net, has a much stronger one for children than generally), much less unaccountable power for parents over children, and free universal public education, often obligatory with permitted substitution of approved private instruction — children are, IOW, educated on a communal and not, or at least far less compared to the system Marx critiqued, dependent on their parents.

It is important to remember that the system Marx sought to destroy and replace is the dominant 19th Century system in the developed world that he named “capitalism” not the 21st Century system that is the product of more a century and a half of changes to that system, often pushed by Marxist and other socialist critics along with other, often more moderate allies (at least, transactional allies).

> Secondly, I do not see how our current understanding of "personal ownership" escapes being "bourgeois private property".

Note that (for example, among many other prior property systems) the feudal system of property that preceded the capitalist system also was not bourgeios private propety, so what is common between that and the capitalist system is not essentially bourgeois property. The distinctive, defining element of the bourgeois property system is marketable property in means of production to which rented wage labor is applied, and it is principally that particular feature that Marx targets for elimination and replacement with control of the means of production by labor when he talks about elimination of bourgeois property.
Amazon stopped having the best pricing long ago, but their real advantage is convenience. Everything is fast, easy, and straightforward - and that's worth the premium (if any).
