that was not at all certain yesterday, and even now there's the constant fact that a border agent can decide to be nasty and use this as a pretext to deny you entry, with no real recourse on your part.

as a parallel example, trump recently decided that you could no longer get your visa stamped in a third country (which a lot of indians did as a matter of course, because wait times for an appointment can be very high back home). there was an explicit carve out for people who had already made appointments at some third country embassy, but a lot of those people went to their stamping appointment and not only did not get the renewal but had their existing visa cancelled (which is apparently within the powers of the embassy official), so they could not even return to the US while waiting for an appointment date in their country of residence, and are basically on unpaid leave right now (best case scenario, would not be too shocked if some of them lose their jobs if they are away for too long).

> Newton’s method isn’t really so useful for cubics (outside of lucky initial guesses), given how simple the algebraic expressions are.

Do you have a better suggestion for a baseline that compares the author’s method? To clarify, it’s clear that this is not evaluating cubics, it’s solving/inverting them, right? The known analytic methods for solving cubics do usually have some precision issues in fp32, depending on what one needs, which is why my question is about precision. (And also wouldn’t mind hearing about the Newton threshold vs perf, since the presentation doesn’t mention it.)

> You’re saying PQ is “downright wrong”? Why?

Yes, PQ is downright wrong because users view content in differing ambient environments. 50 nits in a movie theater and 50 nits on a sunny day are extremely different perceptually.

> How is the TV industry fixing it?

Who said anything about the TV industry fixing it? Mobile is what really highlights how broken PQ is in practice to such an extent that none of the mobile OS's ever show PQ as the spec demands.

BT 2048 arguably redefines PQ into a relative colorspace by defining that 203 nits == "graphics white" which OS' are starting to just treat as SDR white to redefine PQ as a relative colorspace instead of an absolute one. Wayland also adopted this.

But even the TV industry is starting to recognize that. The recently Dolby Vision 2.0 focuses a lot on similarly retroactively redefining PQ as a relative colorspace, as is SMPTE ST 2094-50.

> Absolutely! I was really referring to the LDR color spaces where 1.0 is relative to the max brightness, which is why I qualified my statement with “relative units”. Aside from PQ, nearly all the old color spaces that stop at 1.0 are relative, not absolute… all the non-physical, non-perceptual color spaces like RGB, CMYK, HSL, HSV… and even some perceptual spaces like CIE’s XYZ, xyY, and LAB are all relative with 1.0 meaning max brightness

Just because 1.0 is the max value in a relative colorspace doesn't mean it's necessarily LDR / SDR. Consider for example linear vs. non-linear sRGB. The value 0.5 in both of those means "half of max", yet they represent wildly different perceptual values, right? In that same way, the 1.0 max of any given working colorspace does not have to map to an "LDR" value. Consider for example being able to write directly to the display. 1.0 max value now maps to the max brightness of that display, and whether or not that's "HDR" depends on the display & ambient conditions more than anything else.

For internal passes you almost certainly want to work in something consistent, typically linear, and then yes 1.0 would be SDR white. But the output swapchain is ~never linear, and what 1.0 means depends entirely on what is communicated to the consumer of that swapchain. It has no inherent meaning, no inherent SDR/LDR/HDR-ness. Just like 1.0 of an sRGB swapchain and 1.0 of a Display P3 swapchain have different colors, you can also have different luminance ranges depending on what the specific platform supports and the specifics of the output mode.

I used to sharpen my straight-knife planer blades, planing irons, chisels, and knives with whetstones / water stones. It was too big of a pain in the ass over time, so I switched to diamond stones.

Biggest advantages is that you don't need to pre-soak them and diamond stones don't develop a valley / have to be flattened.

if you plan on getting into sharpening I would just start with a coarse, fine, and extra fine diamond stone and a leather strop w/ stropping compound.

It was never not visible, but it did set off the flamewar detector, which downweighted it off the front page. We eventually turned that penalty off.

Btw, I've changed the HN title to reflect the article's title now. Submitted title was "Visa holders on vacation have 15 hours to return to US or pay $100k fee". I don't know if the article said that when you submitted it (news outlets sometimes update article titles as more information emerges), or if you rewrote the title, but if it was the latter, please don't do that—it's against HN's guidelines. See https://news.ycombinator.com/newsguidelines.html: "Please use the original title, unless it is misleading or linkbait; don't editorialize."

In my experience current AI is still far from reasoning about the kind of hard-to-spot bugs in C that lead to the worst exploits. Rust solves most of these by design. It isn't about adding a second language - it is about slowly phasing out a language that is being misused in areas it shouldn't be in.

C will at some point be relegated to being an educational language, incredibly valuable due to few but good abstractions over assembly. It will continue to exist for decades in most systems, but hopefully it won't be used outside of the maintenance of legacy systems.

Sometimes it seems like half the comment sections (but probably more like 20% lol) have a "what is wrong with all of you" as the top-rated comment, and I have to scroll way down, 5 or 10 top-level comments, before I find an example that it was referring to. It seems to get more votes by dramatizing the "going against the mainstream", when really it is the mainstream. (Which is kinda sad, but not really the worst thing in world, probably a perennial part of human society ...)

That's been the case for several years now. Gone caseless with iPhone X, 12, and 13 Pros for years now and have gotten some scratches to the sides and a small crack on the back glass here or there, but no significant screen scratches or breaks. Some scuffing around the edges is it.

Last time I broke the front screen of a phone was an HTC Evo.

If the current structure stands, where steel imports are tariffed at 50% but Mexican/Canadian autos have no tariffs, and Japanese imports are only tariffed at 15%, the consequence will be the firing of every auto manufacturing worker the US and the shutdown of every auto factory. The consequences will be cruel and fair.

The only reason it is not already happening is because of the TACO phenomenon and the possibility that the courts will intercede to stop the wanton abuse of emergency tariff powers.

But it's not priced for the market of people who buy lots of knives. Because those who buy lots of knives aren't going to be interested in some mediocre knife with a vibration motor attached to it.

Those who are interested in knives would be able to get a more impressive knife for $399. And they are usually the type of people that enjoy sharpening a knife until it cuts better than this ultrasonic knife ever will.

This is a product which is targeted at people who don't really know a lot about knives and prep their meals with a dull blade.

> ABC didn't have to cancel Jimmy and could have called FCC's bluff and tried to file a lawsuit based on 1st Amendment.

I feel like the executives have a civic duty to have resisted, at least for a few days. Caving so quickly weakened the de facto press freedoms. Maybe Kimmel would be willing to soften it or at least not dig in. New evidence was coming out daily, changing the narrative, and he could use that as an excuse. I think the PR hit of caving is worse than you give it credit. I can believe they want very valuable near-term favors from the FCC or their MAGA-aligned affiliates, more than I can believe they thought there was no better PR way out.

> Unfortunately it doesn't work that way. It's specific corner case of FCC licensing.

I'm not saying the FCC should take action against Mike Lee and Nancy Mace. I'm saying Congress should expel or censure them, if this was really about how public figures shouldn't be "spreading misinformation related to a crime" to the public, if it was about using all available legal weight to hold them accountable if they do. (If anyone's wondering, shortly after MN Rep. Melissa Hortman and her husband were killed, Mike Lee tweeted an implication that the killer was "Marxist" and a pun about the governor of the state. Of course he had no evidence, and now, we know it's unlikely given that suspect is a Trump supporter. Nancy Mace made anti-trans allegations about Kirk's killer when virtually nothing was known.)

Congress won't, both because of partisan hypocrisy, and like you noted, sadly, hardly anyone cares about a state-level elected official compared to a famous podcaster.

(Admittedly their comments are very tame compared to the acts that have previously resulted in congressional expulsion. And so were Kimmel’s. But if “protecting the public” angle is all they have on Kimmel, I’m pointing out the other logical conclusions of their argument.)

It's nice to see a few, such as Ted Cruz, calling out the FCC acting like Trump's mafia.

Yeah I understand what you mean, actually I've been investing in Solana, since it's the one that allows for low cost transactions and I feel like it's the network that's actually being used for useful stuff (stripe, visa are working on building on top) so I made 30% in return. Since cryptos are risky I didn't put much money and only made 50$, But I'm faithful of the development of Solana, stablecoins and the like.

I was not aware that she had made this statement as well. All previous reporting from this morning seemed to report back to a Business Insider article that cited only an "unamed White House official who has been granted anonymity to speak on the issue". I missed that it was a reference to a tweet from her specifically (as opposed to one of the countless other accounts copy/pasting this everywhere).

Note that Leavitt's words are any more enforceable though.

At the time, I really didn’t know it was likely fraud due to the low pay aspect. Interesting though about the 6 on 6off, since it looks like they could stay 3 years?

Perhaps that was so they could keep everyone “in the system” by not allowing them to be established, or something? I’m not really sure, but I think it worked kind of like a temp agency, but I believe the pay checks were issued directly by home depot, so I’m really not sure how everything was organized.

The house had an “agent”/handler that basically they had to obey, even though they worked for HD… it felt really Mob-like, with prohibition on dating, being out late, etc and strict organization of work schedules for room sharing.

But they paid 2x normal rent, all in advance, 6 months at a time and the apartments were always in great shape, so the property owner loved them.

Whatever it was it sure smelled like some kind of trafficking to me but I could never put my finger on the exact issue, and they all seemed genuinely grateful to be there. It did seem super shady though.

podman + systemd integration seems really nice now.

given that podman can also have a (nicer?) transition to docker is a plus as well.

There are a lot of paas nowadays which use docker under the hood. I think I would love seeing a future where a paas actually manages it using systemd.

I think this might be really nice giving an almost standard way of installing software.

I really want to try to create something like dokku or some gui for making systemd management easier but I will see some alternatives currently, thanks for sharing it!

I've noticed my iPhone get hot the most while using the camera. Especially while taking video, but after a few photos it gets hot as well. I was on vacations last week in a tropical country and took a lot of photos with my 16 Pro and it gets so hot after just a few photos that it starts lagging A LOT due to the throttling.

I'm sure this is handy for LLM usage, but this was a problem before those were a thing I'd say.

Also, people knew what was on TV before they turned it on.

People bought TV Guide magazine, which was pages and pages of listings, or looked at the TV page in the newspaper.

You also generally had the airtimes for your favorite shows memorized (I bet a lot of people who were alive in the '90s could still tell you when, e.g., Seinfeld, ER, The Simpsons, and The X-Files were on and on what channel number).

“ DARVO stands for "Deny, Attack, Reverse Victim and Offender," which is a tactic used by abusers to avoid accountability by denying their wrongdoing, attacking the victim, and claiming to be the real victim. This manipulation can make it difficult for others to discern the truth and often leads to the victim feeling blamed for the abuse they experienced”

I assume the native Mac-app ecosystem will die from this update. iOS will recover, but for Mac it's gonna be custom designs and electron all the way.

- I haven't dealt much with SwiftUI myself, but several developers mentioned¹ a buggy and unstable migration process to the new design.

- Most pro users (aka devs) are probably not convinced by this design language anyways

- Even before Tahoe, cross-platform apps had been eating away at the native market (Obsidian, Figma, VSCode, 1Password, ...).

- Apps that are still native are usually not best-in-class anymore - especially Apples own apps.

Their reasoning may be that, if Mac apps are dying anyways, they could at least get iPad apps to replace them. If it didn't work for Microsoft, maybe it will work for Apple.

On the bright side, I feel less locked into MacOS now.

I recently started using python packages for some statistical work.

I then discovered that there are often bugs with many of the python stats packages. Many python numerical packages also have the reputation of changing how things work "under the hood" from version to version. This means that you can't trust your output after a version change.

Given all of the above, I can see why "serious" data scientists stick with R and this article is just another reason why.

I actually 100% wrote that comment myself haha!! See https://news.ycombinator.com/item?id=45316437

I think it would have sounded more reasonable in French, which is my actual native tongue. (i.e. I subconsciously translate from French when I'm writing in English)

I'm hitting 2 years after a massive layoff at my previous job. I've worked in more or less all the major languages and tech stacks doing fullstack web + cloud infra + desktop apps for startups in various sectors.

First year was an intentional "sabbatical" after never taking longer than a 1 week long vacation in seven years of full time SWE.

Second year... Well, I've applied to probably around 500 jobs this year, from the smallest to the largest companies, and I've gotten ONE video call interview. And as much as I would want to thank that one VP Eng at that one company for even interviewing me, after the interviewer directly told me that I aligned with what they were looking to hire for the role, and that I would be scheduled for technical interviews the next week, I ended up *ghosted*. Not even a rejection email.

Of my IRL SWE friends, I know many like myself who have been laid off and can't find new work (it seems like the longer the gap gets, the more it self-reinforcingly leads employers to think you're damaged goods); I know others who have been laid off and found new work within a month or two; and I know a few who are continuing to climb the comp ladder at big saas corps, seemingly completely unaffected by the job market.

The strangest thing to me about this wave of SWE unemployment is that it seems to be totally violative of supply and demand. Yes, I know that all SWE workers aren't equal fungible goods, but I would have thought that there are tiers or specializations inside of which there can be some rough supply and demand. Yet, I haven't gotten any lowball job offers - just complete lack of interest.

For past context, I didn't even have to apply for my last 2 jobs - a technical leader at each company (CTO, Dir Eng, etc) reached out to me unsolicited after finding my resume on a job board.

520 hours at $10k/year is only around $19/hour. This is minimum wage in some American cities like San Francisco, and fast-food starting salaries in many other large cities. You're simply not able to hire someone for bespoke meal prep, housecleaning and random errands for $19/hour in America - or if you can, they will either not be competent or move on quickly to higher paying jobs.

Having a housekeeping service come for an hour or so weekly and a lawn maintenance and snow clearing service every two weeks will cost around $10k a year total in many large or mid-size cities, and many upper middle class earners do in fact use those services.

That argument is not sound. English is an official language of India, of course Indians are much more likely to seek work in the UK and the US than people from Latin America. You have failed to present any evidence concerning the skill levels of Indian H1B holders, and, moreover, since India has the largest population of all countries, those 130M college graduates must have gone through some very tough selection.

Yeah I mean, the product is either going to work or it isn't going to work. But the only people who are going to be early adopters for this are knife nerds. Obviously, you'll get a knife that r/chefknives admires for cheaper than that!

I'm not hyping the product. I keep a knife set up to easily slice tomatoes, and if I don't want to clean it carefully afterwards I just use a good thin serrated bread knife. I'm still not really sure what this knife is "for". But I'm also not ruling out that it is "for" something interesting.

In case others are not aware what "pathology scanner" is, apparently it is a device to scan/image microscope slides. Found some specs, apparently these Philips units do 0.25um/px and 15mm x 15mm imaging area, making the output images presumably 60000 x 60000 pixels in size. Apparently Philips previously used their own "iSyntax" format, and also JPEG2000 DICOM files for these devices.

Ultrasonic knives have been available for non-food uses for a long time. They are useful in certain narrow applications, such as cutting leather or some plastics.

That said, they come with two big caveats. First, if you push them into any harder material, the edge is destroyed almost immediately because of the micro-scale "jackhammer" action. So, hit that avocado pit and the knife is probably cooked.

Second, the constant motion heats up the blade, to the point of melting thermoplastics or causing the edge to lose temper if you're pushing a bit too hard, cutting the wrong material, etc.

It's your money, but I suspect this knife is more of a hassle, and requires more care, than a regular kitchen knife. And let's face it, the coolness factor aside, how often do you struggle to cut chicken, tomatoes, or bread? If you do, it's probably because your knife is dull, and this knife will get dull too.

That has not been my experience. I develop on Windows and need to compile for Linux. After spending several hours trying to get cross-compilation working, I gave up and do it via WSL now.

I switched from Go and I feel like Go was much better at this than Rust.

(I tried “cross” but it was very slow and I found it faster to rsync the files inside the container and then run the build scripts)

Yeah, I never understand these caseless discussions.

I went caseless once since I didn't realize my case would arrive a week after I bought the phone.

The phone was slippery (couldn't temporarily rest it on my knee), and I found myself inspecting the restaurant/bar table any time I put the phone down after that one night I placed it right into a puddle of beer condensation and some mysterious food that got in the mic on the back of the phone and grossed me out.

The phone could be indestructible to drops and it still wouldn't solve those issues.

Well, I've heard from from Indian immigrants (to the US) that today's India wouldn't have existed without the British example of bureaucracy. So maybe that, coupled with the caste system and a high reproductive rate, jeopordize the status quo?

With all the money pouring into automation (oh, it's called AI now, sorry) maybe US demand for H1Bs would have dropped off anyways?

I know it's obvious but it seems like a worthwhile discussion.

Ignoring or at least dismissing the similar acts on the left highlights the reason that a third party is necessary.

It’s clear Trump is attempting to capture the institution, and I’m not equivocating, but this has been an escalating ping pong back and forth over the last two decades.

I’d rather live in a unified country. Unity comes from breaking out of the polarization

I don't believe the average American cares about the concerns raised in this thread. Most of them don't have the slightest understanding of how their immigration system works.

I do think that no one would accept this kind of mismanagement if it were to affect them.

Let's say by executive order they make tax day Feb 1st on January 30th. And everyone who's late will pay a hefty fine. See how that would go....

This is no way to make policy, no matter the form of government
