Your claim was:

> It is noteworthy that zapps are based on lightning (which is Layer-2 for bitcoin), and similar in privacy as monero (and instantaneous).

Entire subthread was 99% about your lightning "privacy" claim, which was incorrect.

The difference between minutes vs seconds might be interesting or crucial to many, but that wasn't the most important thing you've been called out on.

Hope this helps with understanding the other guy.

the question was why not use encryption (sqids/hashids/etc) to secure publicly exposed surrogate keys, I don't think this reply is on point .. surrogate keys ideally are never exposed (for a slew of reasons beyond just leaking information) so securing them is a perfectly reasonable thing to do (as seen everywhere on the internet). otoh using any form of uuid as surrogate key is an awful thing to do to your db engine (making its job significantly harder for no benefit)

> You've embrittled your system.

this is the main argument for keeping surrogate keys internal - they really should be thought of like pointers, dangling pointers outside of your control are brittle. ideally anything exposed to the wild that points back to a surrogate key decodes with extra information you can use to invalidate it (like a safe-pointer!)

There are studies that show how heritable intelligence is. Very.

It is quite common people say, that something is only a correlation and not causation. But if you can point to a common denominator, that has been shown multiple times, to have a massive effect, it's not likely to be just a coincidence. Genes are this common denominator. Society and habits (for example, protestants vs catholics) are another.

Things that consistently impact the whole population are not just a random process that picks: "You will be clever, ugly.", "You will be pretty, sporty, but will be dumb." It's always genes, society and habits.

And yet those kids from state schools then come out with more firsts than those from independent schools, showing they were not “dumber” at all - they were smarter.

Really, oxford and cambridge as well as other top universities can have a simple algorithm. They should bias against those from private schools in terms of admissions criteria until the point at which outcomes (as measured by graduating degree scores) are equal. This wouldn’t happen though because then private schools would drop to 5% of enrolments and there’d be no advantage gained from paying for a private school education. Unthinkable!

The HN link is to https:// ... a web browser cannot request the page, and cannot process a redirect unless the server responds with an acceptable certificate. If the server responds with an unacceptable certificate, the browser may ask the user to accept it, in which case the browser could connect and issue the request and receive the block or a redirect.

If the user doesn't click through the certificate error, the user will only know it's blocked (or the server is misconfigured), they won't get information on why it's blocked; perhaps details of the certificate might help narrow down the cause of the block or the agency implementing it.

If the user loads the https page and sees "Access to this page is disabled The law prohibits participation in games of chance organized by unauthorized persons through means of electronic communication." as suggested earlier in this thread, and the user did not click through a certificate error, then the MITM must have obtained an acceptable certificate somehow or broken TLS. Since Sep 2024, multi-perspective issuance corroboration has been required by the CA/Browser Forum [1] and it was a best practice for many years, DNS takeover in a single country should be not sufficient to establish domain control for certificate issuance.

It might make sense to turn over phones every two years if you are a business that maintains lots of phones.

As an individual, I generally keep my phones for at least five years.

Why should I spend $300 per year instead of $150 when the lower cost option works for me?

(I'm typing this on a 2020 iPhone SE; it runs the latest software. Although this year, that's not necessarily a good thing. Liquid Glass, Safari bugs.)

Re ending - while it probably alludes to the fact that we need community to feel better - expecting another person to be able to help you with your emotional state (or expecting from yourself that you might be able to fix someone's emotional state) is a slippery slope.

One might argue that if someone is appreciated on the basis of whether that person makes one feel good in the moment - they are being treated no different than a drug (alcohol, etc). Some argue that such unhealthy dependencies on soothing agents (drugs or people) stems from lack of self soothing skills. Apparently, most "happy healthy people" (there are ofc caveats with this definition but for arguments sake let's assume that we share some understanding of what that means) have an intuitive understanding of how to take care of themselves both physically and emotionally in ways that return them to a baseline state of sorts. If you lack such skills, you often resort to less healthy coping strategies to draw yourself towards this baseline state.

Funny quote from sir Terry Pratchett: Death: "THERE ARE BETTER THINGS IN THE WORLD THAN ALCOHOL, ALBERT." Albert: "Oh, yes, sir. But alcohol sort of compensates for not getting them."

You know what would really be useful is a conformance test based on a particular real implementation.

What I mean by this is a subset (superset?) that exactly matches the parsing behavior of a specific target parsing library. Why is this useful? To avoid the class of vulnerabilities that rely on the same JSON being handled differently by two different parsers (you can exploit this to get around an authorization layer, for example).

> because of style of community they want to own their home in?

No, I do not care about their choices, provided they are willing to bear all costs from it. The problem is not living in the suburbs. The problem is affluent people that have their lifestyle subsidized by poorer people living close to the city center.

Also, it's virtually impossible to claim that people want to live like that in the US, because most places have zoning laws that simply forbid the emergence of any other alternative. Suburbs in Germany are smaller, less dense versions of the urban center, but they are not devoid of life. They are still walkable, they still have local shops, they do not make cars a requirement for everyone, kids do not need to be driven around anywhere, etc. You can bet that if more people in the US could come to visit they would rather live like that than in the traditional cul-de-sacs/picketed fence developments from American Suburbia.

> high school students preparing to go to university are most interested in rankings

Wouldn't league tables like Norrington and Tompkins be more important for them?

I remember during my Britishphilia phase in HS and imagined doing a CS Tripos at one and then a BCL at he other before I removed the emotion and realized the services and network was inferior to a good UC like Cal or UCLA or a B10 like Mich, I was concentrating more on the College itself, not the Uni as a whole. Like being at Harris Manchester College, Oxford wouldn't open the same doors that Balliol College, Oxford would, and it was Oxbridge, Imperial, UCL, LSE, or bust.

At the undergrad level, Oxbridge is college driven and not all colleges are equal even if everyone is in the same faculty.

It's not like Yale or Harvard where you are randomly assigned a house, and the overwhelming majority of education services are provided by departments.

You each view the world differently, and neither of you are right or wrong. I had to learn spherical astronomy to get the East/West flips on basic up-facing first-person charts correct, and I have to invert differently for first- and third-person views in video games. Not to mention the nightmare of how camera independent axes controls sometimes swap “left” and “right” rotation on the Q and E keys because game designers assume that their mental model of CW and CCW inputs is universal across all players and each game has a coin flip chance of being different from the next. It most definitely is not! (Do you slew the camera from the direction, or do you pivot the camera to the direction?)

> 5-10 years means you want a wall phone. There’s nothing wrong with that, but it’s a contrarian position and the options on the market don’t support it well as a result.

Actually no, that's not what it means at all. The phone I want a phone supports various smartphone features like GPS and NFC. It receives regular software and firmware updates, providing whatever new software functionality has been developed lately. It's built to last, without artificial barriers and compromises that prevent 5-10 of use.

The market may not support it very well, especially when looking at the major handset manufacturers. If that makes me a contrarian, fine. But let's not pretend that the "market" (a space dominated by just a few vendors) is optimizing for long-term customer satisfaction or any such things, or that the absence of something in the marketplace means that that things is silly.

I get that you're coming from a specific context, needing and wanting to turn hardware over quickly. But there are plenty of other people (who are generally quieter than tech enthusiasts) who don't have any such need or desire. A well-supported phone with enduring battery technology would be very welcome to me. The fact that the market doesn't meet our needs is reflective of the market-makers, not the would-be customers.

The time of every bright child having Oxbridge as first university pick ended quite a few years ago. Not accurate that parents are saying this either, the change has largely come from parents who are often people doing hiring and have seen the change over the past few years. The very top aren't applying there any more at all, you don't need to: Stanford, Harvard, MIT, all better.

Oxford, in particular, has made their bed. They have made a willful choice to be worse. I am not sure why anyone wouldn't take them at their word.

I moved to a downtown neighborhood a couple years ago, and got rid of my car when I did. This meant way more everyday walking, and I noticed an almost immediate improvement in how I felt. I'm not even walking as much as you are and it still made a big difference.

On days when I end up walking further, like a long distance grocery trip or whatever, I'm tired that day but usually do feel better the next day.

As I understand it, the only organisation that can block the streaming websites without collateral damage is Cloudflare, and they have not chosen to do so.

The situation is a bit irregular, as the streaming providers set up a new website for each game, and the legal system isn't fast-moving enough to issue a court order banning a website within the 90 minutes of a football game. Instead La Liga got a 'dynamic blocking injunction' so they tell ISPs what to block, and ISPs have to block it.

This articles assertions are demonstrably false.

2. Studies showed LLMs made zero improvement in senior coders performance. Note senior coders are usually mostly a self-aware LaTeX macro already.

It doesn't seem to have much in the way of validation, e.g., it will indiscriminately let you use either ']' or '}' to terminate an object or array. Also, it's more lenient than RFC or json.org JSON in allowing '\v' for whitespace. I'd treat it more as a "data extractor for known-correct JSON". But even then, rolling your own string or number parser could get annoying, unless the producer agrees on a subset of JSON syntax.

I knew that crowd during the era of Autodesk ownership.

It was a disaster. There were fundamental problems:

- Nelson had very specific ideas for a database architecture, and they were awful. Links going every which way, all of which had to be consistent at all times. Imagine URLs all having backlinks to all uses of the link. That's Xanadu. You could make this work today, but database architecture of the era was far too primitive. With all that linking, just rendering a page would take a lot of joins.

- Everything is pay per view in Xanadu. What are you going to store? Early thinking was to store the expensive newsletters which investors buy for a few hundred dollars a month. The people involved were way too into microtransactions.

- It was inherently a centralized system, like Lexis/Nexis, or the National Library of Medicine. This would not have scaled, because of the need to keep the backlinks consistent.

- No images. Images didn't fit Nelson's model of text editing. How do you charge for operations on images?

Probably the closest living descendants to Xanadu are the collaborative editing systems where multiple people can work on the same thing at the same time. The text systems for that are well known. There's even a graphical shared editing system, NVidia Omniverse Connector. Nobody uses it. [1]

You could fairly say that China’s pre-Opium Wars obsession with testing and meritocracy based on said testing is what brought them into all that mess, I’m pretty sure that the Portuguese that had gotten all the way from their small country all the way to Southern China using some stingy boats were not clerks nor great (potential) test-takers, and yet it was those Portuguese seafarers that were to change the fate of most of Asia forever, not the test-taking Chinese.

Imagine if the MPAA/RIAA knew about this during the 2000's to use against the Kazaa, Limewire, etc during that era anywhere/everywhere. It is so overreaching the Internet would have been stalled at the time.

It is astonishing the court systems for those countries to allow this if, other than maybe football factors into their GDP (which says something about the nation, maybe they should find something more useful to produce). Just for some silly sports event watching man-children kicking balls around.

I grew up in the US as sports were just something on tv, but this is practically holding the nation hostage as though it were a religion, and the world should stop just so they can sell tickets for the only one god, theirs.

As recent actions against media outlets have shown, the current administration likes to pursue actions against its enemies, so it’s better to fall in line and at least maintain the impression that they’re committed to the administration’s cause.

Long term though, I wonder how many companies would just close down, and worse yet, whether America would continue to maintain its soft power. The so-called trade deficits were instruments, if used carefully, could have brought about reform, and yet the its current leader continues to squander it away, pushing countries further towards an Asian power that has typically not been well known for democratic values (although, again, given the recent actions in America, who’d have thought it’s possible in America either!)

> I don't know, claude did that

I'm the type of reviewer that actually reads code and asks probing questions, and I've heard this from junior and senior devs alike. It's maddening how people say this with a straight face and expect to keep their jobs. If people are pushing code they don't understand, they're liability to their team, product, and employer.

I'm in the middle of submitting PRs to multiple projects because they are compiling on ubuntu-latest and forcing a glibc 2.38 requirement. These are multiplatform projects where most or none of the devs use Linux.

The first project I was able to change their workflow to build inside a 20.04 container. The other project uses tauri and it requires some very recent libraries so I don't know if an older container will work.

Do you have any documentation or generic recommendations for solving these issues caused by blindly using GitHub Actions for all compilations?

If they made my exact Honda civic but with an electric motor and literally no other “improvements”, I’d be over the moon. I don’t need a touch screen, “self-driving” feature, or _electric-only door handles_ - the biggest pain points of cars have been solved for a long time, and Tesla has taken their ability to build great batteries and motors and said “now how can we mess up the rest of what a car is?”
Ask HN: What frustrates you most about video conferencing tools?
by ud0 | 2025-09-21 18:23:23+00:00
I work at a FAANG and have spent the last 5+ years building video conferencing tools. I hacked together a Chrome extension to fix my video colour. I planned to add more features: local recordings, on-device AI transcripts and summaries, and clean screenshots of screen shares. Then my company shut down our in-house tool and moved to Zoom. Around the same time, I joined a new team and had to onboard, which is when I realised I truly needed these features. In technical meetings, I often want to capture a screenshot of a shared screen or record a brief explanation that transcripts miss, with permission, of course.

With Zoom, I'm unable to do any of it because of Admin controls. Many AI notetakers exist, but few run locally, and wiring a Chrome plugin into Zoom is messy. These things are easy & possible, so it frustrates me every time I join a call.

What do you find painful about video conferencing? And if you could design a Zoom/Teams/Google Meet alternative from scratch, what would it do for you?

You've used an analogy instead of an example to demonstrate your point: analogies can be helpful for explaining concepts but are rarely accurate enough to prove logical parity.

It would be much easier to discuss the merits of your argument if you had an example of the dangers of leaking creation timestamps for database entries.

Otherwise, carparks & database creation timestamps have nothing in common that is meaningfully relevant to your argument. You cannot just generalise all worldly concepts & call it a day.

My cynical take is that the leadership in these countries has realized that no amount of hiding under the carpet could save them from the culpability of having actively supporting a genocide, so now they are scurrying like cockroaches trying to distance themselves from the genocidal Israeli state.

We should remember that it was those very same governments that happily supplied weapons to Israel and actively blocked resolutions by the UN to recognize and stop the genocide that's been happening in the last two years. We need to hold our "leaders" accountable and not allow them to escape culpability.
Per-paycheck impact of a $100K H-1B fee at 10–50% pass-through
by lorastonden | 2025-09-21 18:24:29+00:00
I ran offer math for the proposed employer-paid $100K H-1B fee reported by major outlets. Using a 4-year horizon, it annualizes to $25K. If 10–50% is indirectly passed through, the effect is ~$96–$481 pre-tax per paycheck, and delays cost $5.1K–$20.5K in gross pay at a $133,080 salary. The post includes tables, household cost ranges, a rights checklist, and negotiation scripts.

How would you measure this?

Before you continue, there are governments in the UK that have created formulas to mathematically measure your level of "struggle"...these happen to, in a massive coincidence, benefit areas that vote for them.

The same logic is also being applied within universities to boost grades as managers at universities have quotas to hit from government. This leads to odd situations where a subject like Scottish Law at Edinburgh has no quota for students without appropriate social credit because it is a subject which, unlike other courses at that university, gets largely Scottish students applying so it has to be used to fill quotas. And these students have to be carried to the end of their course because they are there to fulfill a quota.

Sounds like a great idea but, as with everything like this, the assumption is that a university administrator or bureaucrat can accurately measure your struggle...they can't, I am sure the wisdom of this approach will dim when you are being operated on by someone who filled a quota at medical school.

Do you not review libraries you add to your project? A quick scan of the issues page if it's on a forge? Or just reading through the code if it's small enough (or select functions)?

Code is the ultimate specification. I don't trust the docs if the behavior is different from what it's saying (or more often fails to mention). And anything that deals with recursive structures (or looping without a clear counter and checks) is my one of the first candidate for checks.

The skills juniors have at any time are more narrow and more focussed on the tasks that are most simple in the current context; new tools that change things inherently are most immediately beneficial to people with broader and deeper skill sets, since they shake up the assumptions on which initial (and thus, junior-level) skill acquisition is based.

But skill acquisition patterns change as the context changes, so juniors end up benefitting, too, but the effect is delayed for them.

Oh, my honest apologies then, Greg! :) I am not a native speaker myself. And as far as i can tell, the phrasing is absolutely grammatically correct, but there's some quality to it that registers as LLM-speak to me.

I wonder how the causal graph looks here: do people (esp those working with LLMs a lot) lean towards LLM-speak over time, or both LLMs and native speakers picked up this very particular sentence structure from a common source? (eg a large corpus of French-English translations in the same style?)

Both of these are correct-ish. You can do a renornalization that resets the operation counter without decrypting on FHE schemes, so in that sense there is no strict limit on operation count. However, FHE operations are still about 6 orders of magnitude more expensive than normal, so you are not going to be running an LLM, for instance, any time soon. A small classifier maybe.
