> What does this have to do with gp's claim about cycle of reprisals by both parties? It can be simultaneously possible to admit that the leader of one party is more sane than the other, and to observe that both parties are engaging in cycles of retaliation when they get in power, and that egging on even more retaliation is going to make the situation worse.

I think the reason we are in the situation we are in now is that the last administration wasn't nearly retaliatory _enough_ after J6

Tariffs are an incredibly tricky system. Two things that look essentially identical can be treated very differently depending on exactly how they get classified in the schedule. Some shoe brands (e.g. Converse) will use fuzzy soles for their sneakers, because it causes them to be classified as slippers instead where the tariff rates are different. The technical words used also tend to drift quite far from their typical meanings. In post-NAFTA automotive, "domestic" included things from Canada and Mexico up until recent EOs re-redefined it again, as an example.

The difference here are going to come down to differences between an unfinished product partially assembled in China and a completed vehicle imported from there and get into very detailed minutae of their value to the production system and its intended usage.

There is a solution called Radiance Cascades [1] which doesn't require a denoiser for rendering real-time shadows for volumetric lights. Unfortunately the approach is relatively slow, so solutions based on denoising are still more efficient (though also expensive) in terms of the quality/performance tradeoff.

One issue with modern ReSTIR path tracing is that currently the algorithm relies on white (random) noise, which contains low-frequency (large-scale) noise, which produces blotchy boiling artifacts at low sample counts. Optimally an algorithm should use some form of spatio-temporal blue noise with exponential decay to only get evenly distributed high frequency samples. But that's still an open research problem.

Ask HN: Learning Linux as a Complete Beginner
by abkt | 2026-01-08 18:07:03+00:00
I want to learn programming on my own with C and Linux, as I want to be a generalist and learn like the developpers in the 80's/90's. I've already found books to learn C (C a Modern Approach by King + K&R) and I've already picked a distro (Debian), but I don't really know how to learn Linux. I don't want to learn by watching YouTube tutorials or by copy-pasting answers I've found on Google (or worse, using AI) in a terminal, because nobody learns anything doing that (yet, my generation thinks this is how you learn any skills nowadays). I want to understand what I'm doing and why I'm doing it. Is there a book for complete beginners that teaches you everything you need to know about Linux ?

The artist Panda Bear has a music video from this time called Crosswords. Uses deepdream about halfway through. I thought it was pretty groundbreaking when it came out a decade ago. Seems much more tame now, by today’s standards, but still gives me the feels

> is it normal, in the USA, for half of all people to only eat beef once every 8 days?

Thats not the implication of 12% of Americans eating 50% of beef by consumed by all Americans that day.

If I had to make up some numbers it’s probably that, on any random day, 12% of Americans ate 50% of the beef (a large burger), 28% of American ate the rest of the beef (bit of lunch meat), and 60% of Americans did not eat any beef.

Without more information about how the system works, a casual "eh if I don't grant location data access to shady apps I'm probably safe" seems very risky. What apps are "shady"? How does the real-time bidding system obtain and divulge location data?

I think that it is not a safe assumption that the only way corporations are obtaining people's location is via OS location APIs.

Again, I’m going to disagree. Boxes for CRTs were massive. I had to RMA my 19” CRT in college and it was heavy, but worse was how wide and tall the box was. I had no car so had to painfully lug it a few blocks to the post office. I can’t quickly find package dimensions, but did find a YouTube video of a guy packaging a 13” trinitron for sale second had. The volume of the box was approx 0.075m³. The retail packaging for a 13” LCD currently available is 0.012m³. I have a 65” TVs that came in a box approximately 68”x38"x8". That’s rough equivalent to the package volume of a 24” CRT.

Costco wasn’t selling 24” CRTs, though, they were selling 27” & higher up to projection. These were massive, maybe three to a palette at most. CRTs needed to get deeper as they got larger, so their packaging grew in all three dimensions. LCDs only get bigger in two dimensions.

Either you never dealt with CRTs, or you’ve forgotten just how massive they were. I still have 25” Trinitron in the corner of my office. It is a production to move it. I could fit at least four of the package boxes for the 27” monitor I just bought for my in laws in footprint of that display.

The purpose of people putting money into stocks or real estate is to allow for a simple, fairly 'hands-off' way to make money (real estate is not totally hands off, but is pretty close to a set-it-and-forget-it business).

Real estate works for this because you can really put in as much as you want into it.

Other business activities do not work because the entrance cost for non-rent-seeking business is extremely high and the risk is way too high compared to real estate. This is due to American regulation and labor laws.

This is a 'first-world problem', but now that I have capital, the question is 'what to do with it'?. Yeah, you could throw it in the stock market, but that's also rent-seeking in a sense because you're not really able to invest in primary rounds (I mean you can, but it's hard to find deals), so basically you're just providing liquidity to people, which is rent-seeking of a different kind.

So then the question becomes what else to do with it? I've given a ton away, but that's useless for the most part since it barely creates any economic value.

In my ideal world, I'd start a factory and hire a manager, but the capital cost of that is high, not because of the material or the rental cost, but because of the labor cost. So then, what's the option? I could easily outsource it all to China or India, but that's completely useless for the United States.

Then the question becomes, why start your own, when you could invest in others. Great! I would love to do that. It would be even better if I could simply invest in a local enterprise... Except, that's not easy either. Regulation over investments means that even investing in this is fraught with difficulty unless you want to establish some sort of 'fund'.

So basically, there's nothing to do with the money, which is sad, since I end up giving most of the money I make away anyway, and would prefer to have more of it to give away.

Until America figures out what it wants to be, it's going to be real estate for me... consistent incomes, fairly uncorrelated with equities (which I have a lot of too), etc. There's really not many other options here. There's barely any 'productive' activities taking place in the United States.

The article leaves out an important contextual quote from Oz: “In the best-case scenario, I don’t think you should drink alcohol, but it does allow people an excuse to bond and socialize, and there’s probably nothing healthier than having a good time with friends in a safe way.”

Actually seems more aligned with the WHO, who now advises that no amount of alcohol is safe.

Realistically, how many drinkers knew the USDA had a recommended “moderate drinking” guideline that flowed to the CDC anyway? People are going to do what they’re going to do. The alcohol cat is out of the bag and we’ve seen that it won’t go back in, at least at the hands of the government.
Show HN: I built a tool to automate fighting school zone speed camera tickets
by todaycompanies | 2026-01-08 18:08:26+00:00
Hi HN, I built SchoolZoneDefense to help drivers contest automated speed camera tickets without hiring a lawyer.
In many states (like FL, GA, NC), these cameras are generating millions in revenue, often relying on drivers just paying the fine rather than navigating the bureaucracy.
The platform uses a "Defense Logic Engine" to identify specific grounds for appeal—ranging from standard procedural errors (calibration records) to physics-based arguments (solar glare) and constitutional challenges (void for vagueness). It then generates the specific legal affidavits and demand letters needed for that jurisdiction.
Would love to hear your thoughts on the approach or any feedback on the site.

Without deep OS support for this kind of thing, I can't imagine it will feel anything like a native experience. There are already much better touch screen experiences with years of development behind them, in the Linux, Windows, Android, and iOS platforms. There's no need to have a janky hacked together version for macOS to try to make it to the same thing.

No, they are not getting worse. Again, look at METR task times.

The peak capability is very obviously, and objectively, increasing.

The scaffolding you need to elicit top performance changes each generation. I feel it’s less scaffolding now to get good results. (Lots of the “scaffolding” these days is less “contrived AI prompt engineering” and more “well understood software engineering best practices”.)

Its important to not be hyperbolic in these times.

The two technologies ICE uses rely on permission for apps tonuse geolocation data for advertising purposes. Same reason you start seeing ads for local things when you travel.

Technically they can subpoena cell records to see which towers your phone connects to, but this is not viable for multiple people.

For privacy, if you care, having a rooted degoogled phone with no sim card is sufficient enough. You can check its signature by using your laptop as a IGW and capturing traffic to see if any apps or services ping anything.

If you want off grid comms, meshtastic devices are very nice, me and my wife use LilyGo Tdeck pluses for comms and finding each other at festivals. The portable modems are also nice because you can use them for GPS for your phone vs built in location services.

I can give you the exact opposite anecdote for myself. Spent weeks with Dr Google and one or another LLMs (few years ago so not current SOTA) describing myself and getting like 10 wrong possibilities. Took my best guess with me to a doctor who listened to me babble for 5 minutes and immediately gave me a correct diagnosis of a condition I had not remotely considered. Problem was most likely that I was not accurately describing my symptoms because it was difficult to put it into words. But also I was probably priming queries with my own expected (and mistaken) outcomes. Not sure if current models would have done a better job, but in my case at least, a human doctor was far superior.

Speaking of roads, everyone points out lifestyle choices, but the lifestyle of popular bands/musicians is also countrywide or worldwide tours. It doesn't look like an easy life, so I wonder to what extend those excesses are related to being on the road maybe half of the year? I think this means no true social life for extended periods of time; not having people you value telling you that you're past that red line is one less safety.

Also, artists in general are a peculiar profile I think. It's not only famous singers that take drugs, commit suicide etc. One can easily find many writers and painters, some of them even only became famous postmortem.

It's more complex than that. When I'm not looking to sell, I certainly don't want the assessed value of my house to increase. That just means, higher property tax bill for me.

Also, houses get older every day. Tastes change - ranch, open-plan, multi-story, multi family get more or less valued as time goes on. Not just 'fewer houses means better resale value'. In fact, a shortage may not change housing prices at all - sometimes it just makes them sell faster.

It's easy to take a complex picture, connect a dot or two and draw a line from someplace to some conclusion. But it's always a trickier picture than that. You gotta consider more dots and connect them all.

The article has the headline "AI Misses Nearly One-Third of Breast Cancers, Study Finds".

It also has the following quotes:

1. "The results were striking: 127 cancers, 30.7% of all cases, were missed by the AI system"

2. "However, the researchers also tested a potential solution. Two radiologists reviewed only the diffusion-weighted imaging"

3. "Their findings offered reassurance: DWI alone identified the majority of cancers the AI had overlooked, detecting 83.5% of missed lesions for one radiologist and 79.5% for the other. The readers showed substantial agreement in their interpretations, suggesting the method is both reliable and reproducible."

So, if you are saying that the article is "not about AI performance vs human performance", that's not correct.

The article very clearly makes claims about the performance of AI vs the performance of doctors.

The study doesn't have the ability to state anything about the performance of doctors vs the performance of AI, because of the issues I mentioned. That was my point.

But the study can't state anything about the sensitivity of AI either because it doesn't compare the sensitivity of AI based mammography (XRay) analysis with that of human reviewed mammography. Instead it compares AI based mammography vs human based DWI when the humans knew the results were all true positives. It's both a different task ("diagnose" vs "find a pattern to verify an existing diagnosis") and different data (XRay vs MRI).

So, I don't think the claims from the article are valid in any way. And the study seems very flawed.

Also, attempting to measure sensitivity without also measuring specificity seems doubly flawed, because there are very big tradeoffs between the two.

Increasing sensitivity while also decreasing specificity can lead to unnecessary amputations. That's a very high cost. Also, apparently studies have show that high false positive rates for breast cancer can lead to increased cancer risks because they deter future screening.

Given that I don't have access to the actual study, I have to assume I am missing something. But I don't think it's what you think I'm missing.

People also wanting to believe there was even a need for sophisticated cybersecurity attack in the first place. In a country where average household income is around $230 per month. In much wealthier country like Russia you can literally buy dump of all possible leaked data on any person for $1 and for $100 you can get all information government have about a person including camera and mobile phone tracking, etc.

And Venezuela is very very corrupt country. No cyberattack needed when you can pay $10,000 - $100,000 for a dude to pull the lever or to forget to pull the lever and literally 99.99% of people in a country do it.

Though it's easy to explain because people in US community have no understanding of what total corruption look like in a shit hole countries.

Sum types can be put into 1:1 correspondence with the integers, barring the inclusion of a non-enumerable type in a language's specification that can be used in sum types. However I would observe that this is generally a parlor trick and it's fairly uncommon to simply iterate through a sum type. As is so often the case, the exceptions will leap to mind and some people are already rushing to contradict me in the replies... but they are coming to mind precisely because they are the exceptions. Yes, you can sensibly iterate on "type Color = Red | Green | Blue", I've written code to do the equivalent in various languages many times and most complicated enumerations (in the old sense) I do come equipped with some array that has all the legal values so people can iterate over them (if they are not contiguous for some reason), so I know it can be done and can be useful. But the instant you have a general number type, or goodness help you, a generalized String type, as part of your sum type, you aren't going to be iterating on all possible values. And the way in which you can put the sum types into a 1:1 correspondence won't match your intuition either, since you'll need to diagonalize on the type, otherwise any unbounded array/string will get you "stuck" on the mapping and you'll never get past it.

So while you can theoretically argue it makes sense to call them an "enum" I don't like it precisely because "enumerating" the "enum" types (being sum types here), in general, is not a sensible operation. It is sensible in specific, but that's not really all that special. We don't generally name types by what a small percentage of the instances can do or are, we name them by what all instances can do or are. A degenerate sum type "type Value = Value" is still a sum, albeit a degenerate one of "1", but nobody ever enumerates all values of "type Email = Email { username :: String, domain :: String }". (Or whatever more precise type you'd like to use there. Just the first example that came to mind.) There are also cases where you actively don't want users enumerating your sum type, e.g., some sort of token that indicates secure access to some resource that you shouldn't be able to get, even in principle, by simple enumerating across your enum.

If it's called an "enum" I want to be able to "enum"erate it.

I'd like to contribute to open source to help and empower people.

Your environmental mission feels moot if you do a lot to help with greenhouse emissions and then proceed to also dump all the waste in the ocean. Your mission is "accomplished" by your hands and you are recognized as a champion. but morally you feel like you took a step back and became the evil you sought to address.

Now apply that mentality to someone in FOSS who sees their work go into a trillion dollar industry seeking to remove labor as a concept from it, and the rest of society. Even of you are independently wealthy and never needed to make money to get by, you feel like your mission has failed. Even if people give you a pat on your back for the software you made.

Many, many, many doctors (including at a top-rated children's hospital in the US) spent 4+ years unsuccessfully trying to diagnose a very rare disease that my younger daughter had. Scores of appointments and tests. By the time she was 13, she weighed 56 lbs (25 kg) and was barely able to walk 100 yards. Psychiatrists even tried to imply that it was all imaginary and/or that she had an eating disorder.

Eventually, one super-nerdy intern walking rounds with the resident in the teaching hospital remembered a paper she had read, mentioned it during the case review, and they ran tests which confirmed it. They began a course of treatment and my daughter now lives normally (with the aid of daily medication.)

I fed a bunch of the early tests and case notes to ChatGPT and it diagnosed the disease correctly in minutes.

I surely wish we had had this technology a dozen years ago.

> What is with people and their need for enums?

I mean, you have atomic and compound data types. Atomic ones represent single values, like "a string" or "an integer", and compound ones represent multiple atomic types combined in some way, like a struct or an enum. Enums are useful for the same reason structs are useful, they do the same core thing, just model it in a different way. It's the difference between "and" and "or", which are both useful tools.

Agreed on pretty much all points. There is no "ultimate audio equipment piece" that is just perfect in all aspects, and the choice criteria are spread across both user preferences and specific use-cases as well.

I love the new airpods pro for my daily commute (subway, not a car; just clarifying before I get hammered down in replies for driving and using airpods at the same time), doubly so given their compactness+heavily improved ANC.

For home, I love my open-back Beyerdynamic DT1990Pro pair, due to the audio profile + insanely good physical comfort when worn for prolonged periods of time.

For gatherings with friends for when I need a somewhat-portable bluetooth speaker (that also happen to look good when sitting on a bookshelf outside of active use), I have a TE-OB4.

If I had a larger living space, I would consider getting a pair of high-quality speakers again too.

But there is not a single "this is it" piece of audio equipment that would just replace everything, so you gotta pick and choose your poison.

Not having read the bible the words sounds so specific and strong.

> Do not trust in a friend; Do not put your confidence in a companion; ... For son dishonors father, Daughter rises against her mother, ... A man’s enemies are the men of his own household.

I guess you have to read the whole thing to imagine the context in which this won't, even accidentally, be interpreted literally. I'm not judging or anything, genuinely curious, obviously these are historical texts from a certain time in history. That's why I'm so curious about the value people see in reading them over and over again in the current times.

The big issue I have with this is no kale or oatmeal in the pyramid image. And rice seems to get a bad rank too. How many fat Asians do you see? People diss oatmeal (lames, tbh) cause of “leaky gut” but is that even a real thing? There’s also glyphosates but quaker is nongmo according to the label. Anyway, I see “leaky gut” and I think quack. The pyramid should have more kale, truly.

Very cool! Would you consider making the streaming backend pluggable? s2.dev could make a lot of sense as a serverless option, and a self-hostable OSS implementation of the API is also coming soon. S2 is great for agent session-level streams (https://s2.dev/blog/agent-sessions), and unlike Redis Streams all data is always completely durable on object storage.

I've daydreamed the same thing.

I can picture my family of four getting on our PJs and hopping in a sleeper car on Friday night. We tell the car if we need to stop for a restroom, or anything else...

And we wake up on Saturday morning, up to eight hours away from home (were we allowed to go 90 mph? Or more?) And then we spend all day Saturday, all day Sunday, enjoying some town. Sunday night, we put on our PJs and hop in the sleeper car. We wake up Monday morning back at home, the kids go to school, and the adults go to work.

I could get to Duluth, Charleston WV, Sioux Falls, Toronto, Pittsburgh.
