I haven't dug into the gory details either, but later they say:

> To fully generalize this into a robust data structure, we need:

> (1) A partitioning scheme that creates recoverable partitions with high probability

> (2) An iterative process that uses recovered values to unlock additional partitions

And they also say:

> With proper sizing (typically m > 1.22d cells), IBFs recover the full symmetric difference with very high probability.

It really doesn't sound like this is both exact and also running in linear time like XOR... right? Perhaps somehow the error is one-sided but then the time bound is probabilistic? If I'm missing something and they're truly maintaining both an absolute guarantee and an absolute time bound, this is mindblowing! But I don't get that impression?

America does have a decent healthcare system for the vast majority of its citizens (people with full time jobs and their dependents, plus the elderly).

That's a large reason why there is no major change in this area, even though one is sorely needed.

Personally, I'd just open Medicare up to anyone who wants it by paying some additional fee each month and see how that goes, but that's too simple for most politicians I think.

> People who know the least amount universities talk the the most confidently about them.

Well, duh. Nobody is going to waste their time talking about something they know well. What would be the point? They already know about it. Anywhere you find people talking about a subject, you know they have limited understanding. That's why they are talking about it — seeking more information to expand their understanding.

> So the money doesn't seem to be used effectively.

That's not what we're discussing. Nor is it even the country we're discussing? The Netherlands has the second highest quality of life in the world.

> It almost like the tax man takes at every opportunity.

Taxes are a requirement of any functional nation. This just sounds like you have no intention of having a real discussion on tax policy.

> It is essentially a gift from the deceased to the beneficiaries.

Yes, that is what inheritance is. And gifts are taxed. At a higher rate than inheritance!

> I don't know what is fundamentally wrong with building up wealth generationally.

Oh, please, don't straw man me.

Nothing is wrong with generational wealth. Looking at the US, you can see how important it is for social mobility, directly affecting the outcomes of minority communities for decades to even centuries. And through systems like the private healthcare and nursing industries, how it's being targeted to extract every last cent out of American citizens before they die and can hand it off to their loved ones.

But are you seriously pretending you don't know what's wrong with a forever growing wealth inequality? Because inheritance taxes only meaningfully apply to the wealthy. We aren't talking working class folk here.

Are we supposed to wonder how will they ever survive on a mere €820.000 that they did nothing to earn? Despite the fact that being raised by someone with that kind of wealth statistically implies that they'll also be inheriting things like property. And that they will have a more stable upbringing with a better education and opportunities their working class peers would never get.

People need to take a step back and take the red/blue team fanboy emotion out of it.

It wasn't "destroyed" because it was "deemed socialist". It was destroyed because it used tricks of law to get something that didn't have broad enough support at the time done and those regulatory tricks were not durable. Same exact story as Roe v Wade but in a much more compressed timeline.

Unfortunately, the whole debacle has likely hardened the resolve of everyone who is against it even though a functional Romneycare system would likely be satisfactory to them (and needless to say an improvement over the status quo).

Turns out "the perfect is the enemy of the good, ship it" isn't how you run a society. This is a common theme. Stuff that's 50-50 either gets gutted or repealed with time. Something needs to be truly popular, like will lose you votes if you undo it, in order to stick around. For example no amount of pothead deadbeats or drunken wife beating is bringing weed or alcohol prohibition back at the state level.

We're 15yr on from the ACA and with very few exceptions things are worse. The nation likely would have been better served by letting the states that were inclined to run such systems continue doing so without federal meddling.

Many people say the first time they use Prozac that it was so helpful they recommended to their friends but then after a while it wore off.

How do you think psychedelics work? They activate the serotonin 2a receptor. It’s nothing but a different drug that effects serotonin. Except it does it more intensely but like all these drugs that act on receptors they wear off because of something what’s called receptor density changes.

For 70 years, we’ve been trying to manipulate receptors into making people feel good. It’s a losing proposition and it’s time to. We changed our thinking. For instance, if these people do have serotonin deficiencies, which is still possibly the case, what is it? That’s causing these deficiencies? Is it low, zinc, low B6, genetics, infection? There’s so many other things that we know that this could be, but we don’t try it.

Your company is passing the ever-increasing costs (which, again, have been on a steady sloped increase both before and after the ACA, since the 1970s; https://ourworldindata.org/grapher/health-expenditure-and-fi...) along to you, yes. This is a significant problem with our system; people think they get healthcare for $50/month, but it's really coming out of a reduced salary.

You're getting fucked (as am I!), but the ACA isn't what's doing it.

FTA: “The laser beam, transmitted with a 20% efficiency rate”

https://www.darpa.mil/news/2025/darpa-program-distance-recor...: “the team measured more than 20% efficiency from the optical power out of the laser to the electrical power out of the receiver at shorter distances”

So, you have to multiply that by the efficiency with which you can use power to generate a laser beam (I see adverts advertising 52% “wall power efficiency”, so I guess a ballpark factor of 2 is reasonable), and that 20% may not have been over 5 miles.
Show HN: GitHub Action for Publishing to Repoforge.io (Python, Docker, NPM)
by chris140957 | 2025-07-18 14:22:55+00:00
I've just released an open-source GitHub Action that lets you publish Python, Docker, and NPM packages to RepoForge.io, a secure artifact registry with a simple pricing model and decent speed.

The action supports:

Python packages via twine

Docker images with login/tag/push support

NPM modules with token-based .npmrc setup

All major inputs configurable (token, registry, tags, etc.)

Fail-safe handling of common cases (e.g. 409 on republish)

Source: https://github.com/chris104957/repoforge-publish-action Marketplace: https://github.com/marketplace/actions/repoforgeio-publish

Future versions will add Conda and Debian package support.

Would love feedback or suggestions!

Quick sneak peek behind the scenes... I've spent years as a software engineer, but I finally decided to try my hand at "vibe coding". I built this game with Replit almost instantaneously. It was a breath of fresh air to build something so quickly after having spent years in the slow development of the real world. I've been tweaking aspects of the game & code for the past week, and I'm sure I'll continue to do so. Let me know if you run into any issues or have suggestions for how to improve it. Is it too easy? Too hard? Too stressful?

Correction, I quoted the wrong price: Honeywell's 4TL837-3D, which is the switch in the 787s according to the SAIB "EASA_SIB_NM-18-33_1-1.pdf", costs about 1300€. MIL-spec &c. certifications are costly. Still cheap enough to not risk killing hundreds of people with the flick of a wrist. Sorry about that.

I found the computer engineering paths to be more engaging from a mechanical sympathy perspective.

Starting from pure abstractions and then maybe dipping into hardware level concerns in later courses seems completely backward to me. Certainly, you can become a very useful employee without any hardware background, but there is a particular spider sense you will not have when presented with scenarios that a hardware person will feel in their bones. The most common manifestation of this is disrespect for memory heirarchy and latency of computational elements relative to each other.

The CS course material became deeply interesting to me only after I encountered specific problems where digging into the theoretical min/max of different algorithms started to produce value in actual projects. When looking at things from the perspective of upper bounds, you will typically find that N is small enough to not matter. Only when it becomes large do the fancy abstractions make any difference at all on actual machines. If your working set fits in L1, O(N^2) scaling probably won't be something you notice in your profiler.

The right wing media ecosystem they have created obscures the fact that Obamacare is the thing these people are using.

Then, once it fails, they will just lie and again blame Democrats for it instead of circling back to their talking points about how they wanted to kill Obamacare.

This is just some people. I have met a fair number of people who just think it is too bad, so sad if you are too poor or do not have a good enough job for good healthcare. I was visiting Canada once, and the folks at the company I was visiting recounted the last American who rolled through who espoused the "well, I guess they die" talking points - to their horror.

But it's not really a "right". The next police commissioner/mayor could conceivably overturn it if they wanted to. That's not the same as most other "rights", free speech for instance. More importantly to this case, because the police only violated a policy and not a constitutional right, the defense can't apply to have the evidence tossed under the exclusionary rule.

interesting notes about the payloads replacing edk for qubes OS. thanks for the review.

i hope they implemented it well. a previous review by someone on here on secureboot implementations and trusted boot got me a bit sad about these libre / coreboot laptops.

this looks more promising from that note. hope they did a good implementation rather than the minimum to expose features.

anyone have any insights on that??

also currently in NL is a big push to move away from foreign tech dependencies (or maybe non euro), so pretty cool to see this is a company from there. might be a nice market opening up for them as that unfolds

I enjoy Foil _because_ of right of way, it encourages blade work, movement and technique. Without right of way Epee is quite boring to watch because the fencers spend so much time trying to figure out how to hit their opponent without being hit themselves, but the lack of rules makes it easy to learn. Saber kind of has the opposite problem in that it's so fast it's hard to watch and there is very little extended blade work. To each their own though.

An interesting confounding variable might be that self taught programmers are likely to be influenced by a background in some other field. For instance, my degree is in physics, so I'm likely to "think like a physicist," if that's a thing. And I've chosen my battles well. My job is in an industry where understanding the workings of a product often starts with physics.

Another variable may be that the training process and the people who go through it are perceptive of what matters to their careers. When I'm tempted to think that engineers "like" to do certain things, and not other things, it could be due to personal ability and preference, but it could also be an economic preference not to waste their time on things that I happen to "like."
Show HN: Free Unicode font generator with 19 styles, client-side processing
by qinggeng | 2025-07-18 14:25:42+00:00
I built a simple tool to convert text into Unicode font styles without the usual bloat of existing generators.

*Why I made this:* Most font generators are ad-heavy, require signups, or have poor UX. I wanted something clean that just works.

*Technical approach:* - Pure client-side processing using Unicode character mapping - No server-side storage or processing of user text - Built with Next.js/TypeScript, deployed on Vercel - Responsive design that works across devices

*Features:* - 19 Unicode font styles (, , , Ⓒⓘⓡⓒⓛⓔⓓ, etc.) - Real-time conversion as you type - One-click copy to clipboard - Hover tooltips explaining each font style - Zero tracking or analytics

*Privacy by design:* Your text never leaves your browser. The conversion happens entirely client-side using JavaScript Unicode mappings.

*Link:* https://cursivetextgenerator.org

The code handles edge cases like mixed character sets and maintains consistent spacing. Happy to discuss the Unicode mapping implementation or answer technical questions.

Looking for feedback on the UX and any additional font styles that would be useful.

Entirely anecdotal: most Americans don't really get it. When people sign up for health insurance through HealthCare.gov, they're just picking a plan and paying their monthly bill. The website doesn't really make it front and center that it's ACA.

People may think they're paying full price because they make some monthly premium payment... which isn't true, as either the government subsidizes a portion of the premium, or you're getting group rates that are way cheaper than if you tried to buy insurance on your own. So even "full price" is receiving a form of subsidization through the operation of the program.

The disconnect is that the media and politicians talk about Obamacare like it's this free healthcare giveaway, so people who pay anything assume they're not on it. They could literally be using the ACA marketplace with 0 understanding that it's "Obamacare". Most people just perceive ACA as government overreach into healthcare, not realizing they're benefiting.

I'm sure it's by design.

No, that's an excuse and not a justification.

You have to log in to the extension to use Privacy Pass. They are fully capable of pulling your block list and removing those entries at the frontend.

And safe search toggling via a query string parameter when using a token does not, in any way, expose any reversible information about a user.

Both this and the underlying system of fact checking are ignoring the elephant in the room: we have no direct access to the truth. Instead, all we can do is check for consistency. This can be either internal (if I say "two is even" and later "two is odd" I must have lied at least once) or with external source (e.g. look it up somewhere, or ask an expert).

The best external source is reality, if you can corner it with a well designed experiment; this is, unfortunately, really, really hard.

Established theories are also good (but, as history has shown, can be wrong). The biggest problem with theory-based fact checking is that our best theories generally come in pairs that make conflicting claims or are otherwise inconsistent. Plus, the proper application of theories can often be a minefield of subtlety. So this comes down to a choice of "pick the theory that gives the answer you like" or "trust the experts" (e.g. argument by authority).

That leaves us with the most popular option: compare the claim against some consensus (and it happens to be correct). This is generally easy, and works great when there _is_ a consensus, which leads us to overestimate its reliability. And thus we waste years exploring amyloid beta plaques, looking for dark matter, teaching whole-word reading, and so on.

It would be great if we had an easy way to tell who's lying, but in fact what we've got is a lot of ways to tell who we agree with and who we don't, and we don't always agree with each other on that.

America's healthcare system is basically a house of cards. Yes for people with jobs and benefits, it works, for now.

But so so so much is wrong financially for hospitals, clinics and pharmacies.

This administration is poking the house of cards with a really large stick.

Pharmacies are so fucked by PBMs( that politicians only pay lip service to dealing with) that they _owe_ money to the PBM everytime they fill many prescriptions. Negative reimbursements. Many small time pharmacies now play games to refuse prescriptions because of how bad it is. PBMs have tried to counter by having distributors write contracts that bar refusals. Chain pharmacies aren't doing much better and are where the negative reimbursement customers end up.

"Mom & pop" doctor offices simply are going extinct. Due to both polticians lumping on requirements for digital records, infinite insurance games and cost of real estate going to the moon, every new doctor just joins a mega-hospital-network because they are already 2 million in debt after schooling. Old doctors just sell out their clinics to those hospital networks. Suddenly doctors that work there get put under strict quotas. This is something I've seen happen in real time in my suburban part of NY. My doctor's office that also fell under the growing blob of a mega-network, now has numerous signs saying "new concerns brought up during the appointment must be done under a new appointment for billing purposes".

The psilocybin containing variety also naturally grow in our yard, and the Amanita is an invasive variety. The "high" people feel is a chemical lobotomy from mild poisoning, and onset of renal failure. Hence why you feel nausea and often erupt out both ends if ingested (especially bad if allergic to a specific fungi.)

I asked for 5 citations not sponsored by dealers that he claimed were available, and my post was flagged. To be fair, I would also accept 3 double-blind medical citations of reasonable quality.

You can't argue with the irrational, as hitting yourself in the head with a brick also causes similar results. lol =3

> Can LLMs do Cobol?

I imagine it's the one place where LLMs would absolutely shine. COBOL jobs are usually very verbose, lots of boilerplate, but what they do is mostly very straightforward batch processing. It's ripe for automation with LLMs.

The flip side is that banks are usually very conservative about technology (for good reason).

I've been doing some recent research and testing, and here's what I have found: I'm talking about the "Penis Envy" strain, which is quoted as being ~30% more potent than typical. 2g is the edge of where I start getting visual artifacting, and only sometimes. 3g, which I have not tried, was quoted as being towards the upper end of a "theraputic dose", and 6g as the upper end of a recreational dose. Some friends with much more experience consider 1g to be microdosing, FWIW. 0.25g I can't feel at all. .5g I start to feel some euphoria and 1g to 1.5g I start to feel "high" but with no noticeable psychedelics or just minor visual artifacting when I'm reading.

I don't really have anxiety or depression. I do have a fairly high stress family life, wife and kiddos have lots of issues. A few weeks ago I had 2g on an empty stomach on a Sunday and I just listened to music for ~4 hours and it was like I had a vacation. I hadn't enjoyed listening to music so much for 20-30 years. Also, I seem to feel kind of sleepy when I'm trippy, but afterwards I'm wide awake for 4-5 hours. So evening dosing is best avoided.

It's kind of great, for me personally, living in a state where it has been decriminalized.

Very old coder here. Wrote COBOL to help Atari add features to a inventory processing system to account for the fact that "inventory" intially was items received at the loading dock, fork-lifted to the shipping dock and shipped. So "inventory" needed to be booked immediately as sales. Now I dabble mostly with Python and JS/HTML. My memory of the Atari gig was that the most critical part was the CICS code. There was just one guy who knew enough to setup the CICS. If he got hit buy a bus... Well after about a year, the bus would not have mattered. Atari buried millions on unsold carts, and I went from working in a beautiful office complex next to Great America Park, to a windowless basement closet somewhere near Mountain View now making changess because the "forklift inventory" version was no longer needed. I know this is a bit off topic, but "COBOL" was the into I needed.

The times seem sublinear, 10k files is less than 10x 1k files.

I remember getting in to a situation during the ext2 and spinning rust days where production directories had 500k files. ls processes were slow enough to overload everything. ls -F saved me there.

And filesystems got a lot better at lots of files. What filesystem was used here?

It's interesting how well busybox fares, it's written for size not speed iirc?

Your peer group consisted of working people who could generally wake up in the morning. Generally healthy people.

Your insured pool now includes people who don't take care of themselves and treat the emergency room like a private doctor's office.

Other countries with government-controlled healthcare introduced wait times to encourage people to consider whether eating that extra donut was worth the health risk. I suspect we'll follow that path, too.

I enjoyed reading the article, I didn't realize I could have this layer of immutability on my OpenBSD systems so easily. But after reading the comments here, indeed the real solution is to export the logs to a central server in another security domain à la PCI requirements.

On the other hand it's great to have documentation like this. I feel there's a gradient between convenience and security and immutable local logs could provide a layer of defense without requiring another server for logging. Maybe a "nice to have" for a small homelab, security practice, etc.

Job applications aren't the only use case for using LinkedIn in this connected way, but even on that topic -- I think we are moving pretty quickly to no longer need to "weed out" AI-written applications.

As adoption increases, there's going to be a whole spectrum of AI-enabled work that you see out there. So something that doesn't appear to be AI written is not necessarily pure & free of AI. Not to mention the models themselves getting better at not sounding AI-style canned. If you want to have a filter for lazy applications that are written with a 10-word prompt using 4o, sure, that is actually pretty trivial to do with OpenAI's own models, but is there another reason you think companies "don't want bots to write job applications"?
