> It seems strange to me that you’re saying doctor salaries are too high

I am not. If anything, I think doctors are underpaid. I would not want to spend my 20s and early 30s in that grind, there are easier ways to earn that much money.

> In the case of UNH, how much money flows as an expense on the insurance side into income on the provider side? Isn’t the relative profitability between these two sides an accounting trick?

UNH’s overall profit margins being much less than pure provider groups shows this cannot be a large effect.

>“Less than $50b/yr profit” as if that’s a small amount.

Nominal profit is a meaningless figure when analyzing the pricing power and/or viability of a business. Profit margin is the only figure to look at here, and there are 6 other publicly listed insurers to benchmark to. Additionally, UNH competes with many large non profit organizations, selling essentially fungible services.

> If it’s so stupid to be a health insurance shareholder, then where does that leave their senior leadership and major shareholders? They’re morons for not immediately divesting and moving into fast food, right?

Depends which fast food. Most are probably even shittier businesses, but if it’s McDonalds which has a decent real estate business, then it might be worth moving. However, the execs would earn far more if they were at similar places in other organizations with higher profit margins, like tech/pharma/finance/oil.

Obviously, if you can’t get a job at Alphabet/Eli Lilly/JPM/etc, then you stay with insurance and earn whatever you can there.

> I fail to see the logic of how "other countries" pay the US when the tariffs are paid by the importer and not the other country which is exporting.

The "logic" is/was that this was a lie directed at his "low information supporters" who tend to simply "believe" whatever he tells them without question. Those same supporters would have been very much against having a "tax increase" levied upon them, but so long as he lied to them and told them "the other country pays the tariffs" then they were fooled into not understanding the tariffs were just a tax increase and so were "in support" of the tariffs.

That was the sole logic -- although there have been times when I've seen news blurbs that have made me wonder whether Trump himself actually believes his own lie about "other countries pay us" in regards to tariffs.

I've been reading Rory Sutherland's book Alchemy and it's full of fascinating insights about marketing/branding etc

Case in point:

- company was testing out their mail based fundraising drive

- they randomly tested cheap vs expensive envelopes, regular envelopers vs side opening envelopes etc for how people could send back a check

- they found that expensive envelopes beat cheap and side envelopes beat top loading

The part that was fascinating is that many folks would think "what difference does it make what kind of envelope you use?". Sutherland points out that putting a check for a large amount in a cheap envelope somehow feels "wrong" even if people can't verbalize this.

Another example is how in the 1950s many food engineers were obsessed with the idea of "food nutrient pills" and how they would replace cooking and eating out in restaurants. While it's true that things like Soylent and Huel made inroads with the tech crowd, most people still love going out to restaurants. The point being b/c eating out isn't only about eating: it's also about taking your wife out for your anniversary or meeting your siblings who are visiting from abroad.

I mention this b/c the HN crowd tends to be very logical/rational (including myself) and this book was a real eye opener around how people actually make decisions.

I've said this a million times to people in this industry: we have a Real Problem with adderall, it's abuse, and the way it robs a person of their ability to feel empathy. Yes, you're a 10x engineer, yes you write amazing code, yes you can work and work and get. it. done. But you'll also be A-OK with dark patterns, just fine with spying on people who aren't you, and hell, you might even think building the first Terminator robots is an interesting project.

Hyberbolic? Sure. But we live in a society that reinforces the idea that the performance enhancement is worth it. But there is a cost, and what you've described is it.

IMHo the main use case is keeping up with a crazy world in data not words written by other people. I have trust issues with the media and with social "new media" and just crave data so I can form my own views as best I can and decide what to research into deeper. It's extremely chaotic and I expect it to get even more chaotic. I can see other uses, such as in prediction markets, investing, journalism as well. But mine is more of the pure play "monitor the situation" type.
LEDs/M vs. 60 LEDs/M: Solving Dotting and Voltage Drop
by emmasuntech | 2026-03-06 02:16:36+00:00
Many makers default to standard 60 LED/m strips, but they often result in visible hotspots ("dotting") unless used with thick diffusers that kill 30-40% of the light output.
I've been digging into the specs for High-Density (120 LEDs/m) strips to see if they are worth the extra cost and complexity. Here is what I found:
1. The "Dotting" Physics
With 60 LEDs/m, the gap between sources is ~16mm. In a channel with a depth of <10mm, the light doesn't mix well. Moving to 120 LEDs/m halves the gap to ~8mm, allowing for a seamless "neon" effect even with clear lenses.
2. The Current & Voltage Drop Trade-off
This is the critical part often missed:
12V Systems: Doubling the LEDs doubles the current (Amps). On a 12V strip, this causes massive voltage drop. You might see the end of a 2m strip dim by 20%.
24V Systems: This is the sweet spot. 24V 120LED/m strips maintain efficiency with half the current of their 12V counterparts, allowing for longer runs without power injection.
3. Thermal Density
More LEDs in the same footprint means higher heat density (W/cm²). You must use aluminum channels for thermal dissipation, or you will accelerate lumen depreciation.
Has anyone else experimented with 144 LEDs/m (WS2812B style) for architectural lighting? How did you handle the data refresh rates vs. power?
Show HN: Virtual Indoor Cycling App (Now with Shiny GTK4/Adwaita GUI)
by richbl | 2026-03-06 02:16:59+00:00
I wanted to share that we've recently released a GUI (GTK4/Adwaita) for our indoor cycling application called BLE Sync Cycle (BSC). BSC was created to allow cyclists to train indoors in front of a big-screen monitor using a BLE speed sensor that syncs with video playback. So, the faster you pedal, the quicker the video playback. Imagine an open-source Zwift or Rouvy that doesn't require special training hardware.

- GitHub site here: https://github.com/richbl/go-ble-sync-cycle
- Applications details including installation and configuration: check out the BSC project wiki (https://github.com/richbl/go-ble-sync-cycle/wiki)
- Project roadmap (https://github.com/users/richbl/projects/4)

From the BSC wiki about where to find videos to use for cycling playback: "...look for videos that are first-person cycling, driving, or even running videos. Check out YouTube(https://www.youtube.com), Vimeo(https://vimeo.com), Pexels(https://www.pexels.com/videos/), or DailyMotion (https://www.dailymotion.com/us), and search for "first person cycling" or "POV cycling" for some great ideas."

And, of course, the next time you're planning an outdoor cycling ride, strap on a camera and record some first-person cycling videos, and share them with this BSC Virtual Cycling community!

As this is an early (pre 1.0.0) release, we're looking for cyclists to help us continue to shake out bugs and make recommendations/suggestions to continually improve the BSC experience. Thanks much!

If the country wage wars for bad reasons, that is another problem that probably should be fixed elsewhere, or you should leave that country and be somewhere who government you can fully get behind.

> defending your country

I am afraid that this does not always have to be an incoming attack. What if some country has a resource that your country badly needs, without which your people will suffer badly and imagine the same is true with the other country. How much of an hit on economic and QoL are you willing to sustain before you ask your government to go out there and get the required resource by force.

I totally get that war is profitable, and most of the wars cannot be justified. But ideas like this sounds like sabotaging your own country and thus your own existence.

I agree with the premise, and note well: food has just finished its Brand Age. The combination of dark kitchens and last mile delivery has shown clearly that consumers have little loyalty to brands and simply want convenience at a reasonable cost. From this lens, nearly the entire QSR industry which dominates food particularly in America is about to tank, and indeed many of them already lost 30-80% value in 2025 (Sweetgreen, Krispy Kreme, JITB, Cava, Shake Shack, Portillo's), but the new reality isn't yet priced in. The vast majority of them operate on a brand and franchisee model meaning they're structurally incapable of exiting the paradigm. We're about to use automation exploit that: zero brand investment, 100% CVP. Now seeking capital partners for at-scale GTM. https://infinite-food.com/

It should be noted that a significant reason that the average selling price (in constant dollars) is so much higher now ($50000 according to the article) than it was many years ago is that people are buying a higher percentage of large cars and/or luxury cars.

If today you are buying something equivalent to what you would have bought in the past there is a good chance you will be paying a similar amount in constant dollars.

The article links to a site that gives a list of the cheapest new cars right now. Here they are. These all include the destination charge.

1. 2026 Hyundai Venue SE: $22,150
2. 2026 Chevrolet Trax LS: $23,495
3. 2026 Kia K4 LX: $23,535
4. 2026 Nissan Sentra S: $23,845
5. 2026 Hyundai Elantra SE: $23,870
6. 2026 Toyota Corolla LE: $24,120
7. 2026 Volkswagen Jetta S: $25,270
8. 2026 Mazda3 2.5 S: $25,785
9. 2026 Honda Civic LX: $25,890
10. 2026 Buick Envista Preferred: $26,495

I bought a Honda Civic in 1989. According to the bls.gov inflation calculator the $25890 for a 2026 Civic LX would have been $9600 in 1989. The MSRP for an 89 Civic LX was ~$10200.

Guess what the average selling price of a new car was in 1989? $12000, which using the bls.gov calculator would be around $32000 today. In 1989 a car like the Civic was a lot closer to what the average car buyer bought than it is today.

Note: the bls.gov inflation calculator is based on the consumer price index. It might be better to compare using the Social Security index factors, which is what the Social Security Administration uses to normalize earnings from different years when calculation benefits. Using SS index factors $25890 today would be $7450 in 1989.

I've done similar calculations for my 2006 Honda CR-V with similar results. Same for the Sentra I had before the Civic.

Considering how much more safety and driver assist features are in these cars compared to the same models from even only 10 years ago, the price being nearly the same in constant dollars is actually great remarkable.

For those of us who prefer cars that are just big enough for our actual passenger/cargo carrying needs or big enough to not feel cramped (whichever is larger) the last 40+ years have been great. We pay about the same in constant dollars or a little less each time we get a new car, and it has better fuel efficiency, better safety, and better driver assist.

> want to make this about a brand, and not a platform, because the Apple platform is very low ranking in the larger world of Smartphones.

Let me get this straight: you believe the iPhone "is very low ranking in the larger world of Smartphones" even though it's the most popular and best selling smartphone in the five largest economies on the planet.

I posted the 5 top selling smartphones in the European 5, United States, Australia, Japan, and China—out of 25 models listed, 80% (20 out of 25) were iPhones.

Don't hate the player, hate the game. No matter what you believe, the number are the numbers:

- Apple’s iPhone marketshare in the US is 60% vs Samsung’s at 22%

- the iPhone alone brought in $209,586 billion in FY 2025 [1]

- if the iPhone were its own company, it would be #9 on the Fortune 500

- Apple's iPhone revenue is greater than the revenue of Dell, Hewlett-Packard, Intel and AMD combined.

Apple tends to expect a lot from its developers. Changing processor architectures is a big one. Unlike other platforms, Apple cuts support and moves on. If an app is abandoned, it starts to show sooner on Apple platforms than anywhere else.

If it’s something that will become critical to a user’s workflow, that can be a big problem. Why invest in an app without a future?

firefox crashes... decently often for me, but it's usually pretty clear what the cause is [having a bunch of other programs open]. every time i can recall my computer bluescreening [in the last year~, since that's how long ive had it] it was because of firefox tho.

this may have something to do with the fact that my laptop is from 2017, however.

Around 10 years ago, in college, in Calculus class I had a very ambitious classmate, wanted to go to DARPA and work on Robotics. I asked if he was thinking it through solely from technical perspective or considering ethics side as well. Clearly, he didn't understand the question and I directly inquired - what if the code you write or autonomous machine you contribute to used for killing? His response - that's not my problem.

After spending couple of years studying in the US, I came to conclusion that executives and board members in industry doesn't care about society or humans, even universities don't push students towards critical thinking and ethics, and all has turned into a vocational training, turning humans into crafting tools.

The same time, at Harvard, I attended VR innovation week and the last panel discussion of the day was Ethics and Law, which was discussed by Law Professor, a journalist and a moderator and was attended a handful of people. I inquired why founders, CEOs or developers weren't in part of the discussion or in attendance? Moderator responded that they couldn't find them qualified enough to take part in the discussion. The discussion basically was - how product companies build affects the society? Laws aren't founders problem, that's what lawyers are for, and ethics - who cares, right?

This frenzy, this rat race towards next billion dollar company at any cost, has tore down the fabric of the society to the individual thinking level; or more like not thinking, just wanting and needing.
Ask HN: How are you using multi-agent AI systems in your daily workflow?

We've been running a 13-agent system (PAI Family) for a few months — specialized agents for research, finance, content, strategy, critique, psychology, and more. They collaborate, argue, and occasionally bet against each other on our prediction market.

Curious what others are building. Are you running multiple AI agents? What architectures work? What fails spectacularly?

The book that changed the game for me is “Leadership and Self-Deception”. The thesis being that the root of resentment is self-betrayal, where self-betrayal is denying your impulse to do right by others.

Ever since I read it, I’ve been more aware of when I am fixated on I and me.

It’s amazing. You can be completely “right” about a situation, yet still be fixated about the self. Escaping the box - terminology from the book - doesn’t change what’s real, but absolutely changes how you feel, and how your situation progresses.

Whether it is self help or blame or resentment, they are all in the box activities. There is another world- a better world.

I've spent 20 years working and 8 in the industry. Definitely feel jaded and looking for an exit. The push to use AI whenever possible, the repetition of the work, the cluelessness of leadership, the rounds of layoffs, and the Return To Office even if it reduces productivity have all worn on me. The high compensation has kept me here longer than I probably should have stayed. A lot of my "issues" would be noticeably better if I worked at a startup instead of a megacorp, but then the compensation wouldn't be as good. Also ... just staring at a screen all day. I daydream about being in nature and find a lot of my senior coworkers do as well. Maybe a year off would help.

> If AI removes one of my co-workers, our competitors will keep the co-worker and out-compete us.

This assumes that the companies' business growth is a function of the amount of code written, but that would not make much sense for a software company.

Many companies (including mine) are building our product with an engineering team 1/4 the size of what would have been required a few years ago. The whole idea is that we can build the machine to scale our business with far fewer workers.

Proton Mail complied with a legal demand they had no choice but to comply with, providing the basic shred of information the user willingly and knowingly provided.

You want to be anonymous? Don't use your credit card! Don't connect from your home internet connection. (I don't know whether this person did because I can't read the story due to login-requirement). Either way, total non-story. Anyone whose potential adversary is a powerful government should already know this stuff.

Either way, Proton didn't help the FBI. The article title is deceptive and implies a degree of insidiousness or dishonesty that has not been demonstrated by Proton in this case.

War is not moral. It may be necessary, but it is never moral. The only best choice is to fight at every turn making war easy. Our adversaries will, or likely already have, gone the autonomous route. We should be doing everything we can to put major blockers on this similar to efforts to block chemical, biological and nuclear weapons. The logical end of autonomous targeting and weapons is near instant mass killing decisions. So at a minimum we should think of autonomous weapons in a similar class as those since autonomy is a weapon of mass destruction. But we currently don't think that way and that is the problem.

Eventually, unfortunately, we will build these systems but it is weak to argue that the technology isn't ready right now and that is why we won't build them. No matter when these systems come on line there will be collateral damage so there will be no right time from a technology standpoint. Anthropic is making that weak argument and that is primarily what I am dismissive of. The argument that needs to be made is that we aren't ready as a society for these weapons. The US government hasn't done the work to prove they can handle them. The US people haven't proven we are ready to understand their ramifications. So, in my view, Anthropic shouldn't be arguing the technology isn't ready, no weapon of war is ever clean and your hands will be dirty no matter how well you craft the knife. Instead Anthropic should be arguing that we aren't ready as a society and that is why they aren't going to support them.

I don't know if sketchy is the right word but every* time I encounter a proton mail user on a mailing list, they are tinfoil-hat paranoid. Like they are a random nobody, but they are convinced that "the Russians" or "the Chinese" are constantly hacking at their laptop and they are constantly trying to harden everything so much one wonders why they even bother using computers at all.

* OK "every" is an exaggeration but enough that the impression has been formed.

Correct that there was no Iraq generation because there was no draft and numbers were way smaller. Vietnam had over half a million troops at the height of that war. Iraq had under 170k.

But the war was still deeply unpopular. There is a reason America did the extraordinary - to that point - and elect its first black president.

The economic toll will be greater with these wars than Vietnam.
