Similar situation, but I had (and still have) issues with the heart, and not sure whether they were from undiagnosed covid infection (never had typical Covid symptoms, and all tests for it came negative), or some rare complications from the vaccine.

I started having heart flutters a day or two after my shot and had severe fever (I was 25 at the time), but the former never went a way. I brushed it off as a temporary symptom and typical after shot reaction (well, fever was at least). Heart flutters never went away and I didn't go to the doctor for at least a few months, it became so frequent that I could not sleep, exercise or even climb the stairs anymore without heart feeling like it's about to explode out of my chest. Not the high heart rate, but abrupt, irregular vibrations/twitching and sometimes feeling like you get punched in the chest, just from the inside around the heart area. Anyway, it happens frequently and in any situation, even at rest.

Got diagnosed with third degree AV block. The flutters were due to the significant damage to the heart muscle, which caused the failure of the conduction system - signals from the upper chambers did not always reach the lower chambers.

I am not angry at anyone or anything, just disappointed. It would feel a lot easier if it was some obvious bad decision of mine, like drinking, doing drugs, smoking, or being overweight, but I did not nor were any of these things. I still keep categorizing life as "before" and "after".

Couldn’t it be the other way round, that changes in health caused by other external factors erroneously get blamed on COVID?

For instance, a disproportionate amount of long COVID cases are reported by women between the ages of 40 and 60, the exact age range when most women experience menopause [0]. Menopause can cause brain fog, fatigue, and other symptoms that mirror those of long COVID. Since pretty much everyone has had COVID, it’s a basic statistical certainty that many women caught COVID exactly when their menopausal symptoms started (whose onset can be extremely sudden), and falsely causally associate the two. The exact same conflation likely happens in children, who also go through several profound developmental shifts.

There's a recent Reddit thread with some good discussion around modules where Ron Pressler took part. tl;dr: the architects acknowledge uptake outside the JDK has been slow, largely because there have always been few benefits to modules, and secondarily because build tool support is lacking (perhaps because of the first reason). At some point they may begin providing additional benefits to modularization which may help stoke demand.

Thanks for the links, that is great to know. I'm not quite sold if it's the better approach. You'd need to do SfM (tracking) on the out of focus images, which with macro subject can be really blurry, I don't know how well that works.. and a lot more of images too. You'd have group them somehow or preprocess.. then you're back to focus stacking first :-)

What is the issue with the permission model. It's basically the AOSP permission model. The changes made by GrapheneOS is the user-facing toggle for the INTERNET permission, and the sensors permission.

If people do not want to interface with those features, they can simply skip them, and the permission model will be the exact same as it is on Android.

I feel invited by the light-hearted nature of this project (and the beauty of this particular Sunday) to make a light-hearted observation of my own. The idea of a programming language that reads like a spell book...but what about a programming language that reads like Principia Mathematica[0]? How would that work, and would it make sense?

Flipping through it just now I was struck with several observations. First, it has a very formal structure (Proposition N Theorem M Phenomena P etc). And also the sheer amount of work he did in (Euclidian) geometry prior to even discussing gravity or calculus. But most remarkably of all, how little a computer would have helped Newton in his work. Oh sure, a computer would have helped Kepler a great deal! And even Newton is not without his tables. Newton would have really enjoyed Mathematica, but even it would have been useless since it assumes what Newton sought to prove.

In any event, this all leads me to realize what a narrow place traditional computation has within the entire field of human communication. The optimist in me sees this as affirming the unique power of the human mind; the pessimist notes that there are always more ways to get a problem wrong than to get it right.

P.S. The Principia is as often a philosophical work as a scientific one. Consider this excerpt:

RULE I. We are i’o admit no more causes of natural things than such as are both true and sufficient to explain their appearances.

To this purpose the philosophers say that Nature does nothing in vain, and more is in vain when less will serve; for Nature is pleased with simplicity, and affects not the pomp of superfluous causes.

RULE II. Therefore to the same natural effects we must, as far as possible, assign the same causes.

As to respiration in a man and in a beast; the descent of stones in Europe and in America ; the light of our culinary fire and of the sun; the reflection of light in the earth, and in the planets.

RULE III. The qualities of bodies, which admit neither intension nor remission of degrees, and which are found to belong to all bodies within the reach of our experiments, are to be esteemed the universal qualities of all bodies whatsoever.

These Rules of Newton have become so far subsumed into the zeitgeist that we hardly ever repeat them. (It reminds me of the feeling I got reading Descartes math papers). Indeed, most modern physicists scoff at philosophy for just this reason, because to them it's been "solved" and remains only as a jobs program for verbally talented charlatans. This is deeply unfortunate for at least two reasons: first, it is dangerous to assume the basics will always be in place; civilizational drift is quite real. Second, you give up using those same tools to advance human knowledge further - if Newton was able to use philosophy to clarify his point and purpose, surely another scientist might as well.

The WHO [1] has a clinical definition of the disease and some basic data on chance of Covid infections turning into Long Covid. Then the meta study by Eric Topol and Zayad Ali-al from last year is probably a good primer into what is known about the disease that is well established science [2].

Its not a big unknown anymore, its very prevalent, it has a lot of symptoms, it has a clinical definition but its problematic and there are many diagnostic tests that can detect parts of the condition but none has yet reached sufficient prominence to be adopted by healthcare. Healthcare is largely ignoring that Long Covid exists so you can't get diagnosed with it but its very much a real thing and a lot of people have it.

> But if you pee on the strip and it changes color you lose weight faster than caloric restriction accounts for, if you eat too many peas and it stops changing color you don’t.

And it's that logic exactly that I'm characterizing as "voodoo". You're trying to cite as obviously true what research simply hasn't shown. "I read it on a blog and it works for me" is the first step on the road to ivermectin and chemtrails.

Double blind study or GTFO basically.

The actual system is that they used a relatively complex zero-knowledge set-matching algorithm to calculate whether an image was a match without downloading or storing the set of hashes locally.

That said, I think this is mostly immaterial to the problem? As the comment you’re responding to says, the main problem they have with the system is mission creep, that governments will expand the system to cover more types of photos, etc. since the software is already present to scan through people’s photos on device. Which could happen regardless of how fancy the matching algorithm was.

ease of initial understanding is not the only definition of good UX. Some UX is optimized for one time use with no familiarity (wizards work well, like checkout flows). The opposite is designed for use every day. In real life professions it takes a lot of work to learn to use tools effectively. That’s not because they are poorly designed, but because they target optimal performance after an initial learning period.

Software has many successful examples of the latter but it’s not a paradigm that designers are familiar with or that startups tend to go after.

iirc Atom was the original Electron project. Eventually VS Code came along and took all the good ideas - the modularity through extensions, and Electron / web based cross platform, but made it really fast and added IDE like language support through LSP. Atom may be dead now, but the idea lives on in VS Code and the new project by the original developers of Atom: Zed

Bitcoin Core v30.0 now relays/mines txs with multiple OP_RETURN outputs and raises the default -datacarriersize to 100,000 bytes. This is a mempool policy change, not consensus. The move has already gotten negative feedback from devs worried it invites more arbitrary “junk” data on-chain. Bitcoin Core’s stance is harm-reduction: OP_RETURN is prunable and cleaner than UTXO-stuffing workarounds that people have been using anyway. Economically, more fee-paying bytes means miners are unlikely to reject it.

I had wireguard on docker before for some containers, but it felt clunky and it over complicated the network stack in my head (I'm unfortunately not very skilled in networking in general). So I said that I'd go back to the root and run it at OS level because then I can expose Proxmox to the world or any of the other VMs I run by having them join the wireguard network. Which in turn means that I can connect to any machine I want/need directly. I am also playing around with writing my own dynamic DNS worker in C# and I was curious on how I could have that run as a systemd process but bypass the wireguard tunnel to keep updating IP addresses. A lot of these were tied to me just being a bit more curious about the whole stack.

>It would be "more secure" to have a per-application firewall that blocks particular apps from outbound traffic over certain networks or to certain destinations. This prevents a malicious app from consuming roaming data.

LineageOS can have that, at the owner's preference. Graphene explicitly forbids it.

Not sure what is meant by forbidding it? GrapheneOS provides per-app network access control via a user-controllable Network permission which is not implemented in AOSP or LineageOS afaik. They do not forbid using local firewall/filtering apps like RethinkDNS (to enforce mobile data only or Wi-Fi only iirc) and InviZible. They only warn that 'blocks particular apps from outbound traffic ..to certain destinations' cannot be enforced once an app has network access which makes sense to me.

>It would be "more secure" to allow backing up apps and all their data. This would mitigate the damage of ransomware. Graphene, again, forbids it (following google guidelines prioritizing the wishes of an app's developer over the device owner).

Contact scopes, storage scopes, the sensors permission and the network permission are examples that show precisely the opposite (GrapheneOS prioritises the device owner over the application developers). To my understanding, the backup app built-in to GrapheneOS even 'simulates' a device-to-device transfer mode to get around apps not being comfortable with data being exfiltrated to Google Drive. That being said, I understand they have plans to completely revamp the backup experience once they have the resources to do so.

All my ideas :')

Also, I did not experience them personally, but I love watching computing history videos on YouTube, and a lot of the computers and operating systems from the 1980s and early 1990s got buried too soon, mostly because of their owners being short-sighted idiots in not realizing the full potential of what computers and video games could become, and having wildly successful hits on their hands with legions of faithful fans but not knowing how to build on that success or what the fans actually wanted to see in updated hardware.

Assume for the sake of argument, that this is literally sorcery -- ie communing with spirits through prayer.

_Even in that case_, if you can design prayers that get relatively predictable results from gods and incorporate that into automated systems, that is still engineering. Trying to tame chaotic and unpredictable systems is a big part of what engineering is. Even designing systems where _humans_ do all the work -- just as messy a task as dealing with LLMs, if not more -- is a kind of engineering.

> rules learned over many years

How do you think they learned those rules? People were doing engineering for centuries before science even existed as a discipline. They built steam engines first and _then_ discovered the laws of thermodynamics.

They mostly took inspiration from other languages for UV. Cargo (Rust) was a huge inspiration, but they got stuff from Ruby as well, I believe. There was an episode on "the changelog" about it. Don't remember them saying anything about PEPs, although that might just be me not having listened to the entire thing. However, the Charlie Marsh was extremely insistent on the advantages of being a polyglot and hiring people with diverse programming experiences. So I think it's quite safe to assume that played a bigger role than just PEPs.

Spring is written by a committee of junior developers trying to implement the ideas from a committee of slightly less junior developers. Which is to say it's a huge unintelligible mess. As the other commenter attest, it works really well if you need the one thing it does - unfortunately the moment you need something slightly different you are forced to dig deep into the insane internals and it is a disaster. This moment comes very quickly too in every project because it was written by people with no experience in real projects.

I was all gung ho on XHTML back in the day until I realized that a single unclosed tag in an ad or another portion of our app that I had no control over would cause the entire page to fail. The user would see nothing except a giant ugly error. And your solution of rendering the rest of the page in Times New Roman isn’t an option. Do you try to maintain any of the HTML semantics or just render plain text? If it’s plain text, that’s useless. If you’re rendering anything with any semantics, then you need to know how to parse it. You’re back where you started.

Granted, I could ensure that my code was valid XHTML, but I’m a hypermeticulous autistic weirdo, and most other people aren’t. As much as XHTML “made sense”, it was completely unworkable in reality, because most people are slobs. Sometimes, worse really is better.

> Laravel..Redis, and PostgreSQL

From the title's "minimal web app", somehow I imagined a local/offline-first static site with a sprinkle of JavaScript, that fits in a single HTML file. Not sure I'd say Laravel with two databases is minimal, or the choice of React. Well I don't mean to criticize, just mentioning what I expected versus what it is, a solid full-stack application.

I like the minimal UI. On navigating the list, it takes a slight delay between clicking previous/next and for the list to update. The experience might be improved with a small loading indicator somewhere, or a fade transition, so the user can see it's doing something instead of "freezing" for a moment.

But if I were to be honest, I wouldn't want to depend on someone else's server for my radio listening needs, storing favorites, etc. At the least I'd want to export/import the data. It seems the app is not open source, so if one day the site was down or the domain gone, I'd lose my preferences.

There's a number of existing web radio players, like radio.garden, so what I probably want as a listener is a list of alternatives and feature comparison, to choose one based on my wishes. (Apparently many of them are called "internet radio".)

Anyway I upvoted because I like "Show HN" projects and respect that you built and shipped it. I imagine it's satisfying to make a useful tool exactly how you like it, and probably others will too.
by the__alchemist | 2025-10-12 14:03:18+00:00
Maybe we are all just ranting into the void when posting on HN. Are you ranting into the void as well? Where should we demark this classification's borders.

I felt the post you replied to was valuable, as it provided a general (but not grounded strictly in the facts of a specific example) outline of how these work.

I will corroborate the details. I learned Django 15 years ago, still use it, and use about 30% of its functionality. I don't think I do anything with it now I couldn't have in the earlier versions.

I won't make a claim to the accuracy of the numbers, but I can offer an example of how long COVID can be undercounted. My daughter was a competitive long distance runner. Months after recovering from the acute symptoms of COVID, her performance numbers were still about 10% down and no amount of training would allow her to reach her previous level of performance. After many visits to doctors and specialists, she was eventually diagnosed with long COVID due to lung damage. She's still very fast by most measures, but in track, the difference between being in the 99th percentile and the 89th percentile is the difference between a top 3 finish and a bottom 3 finish. This basically ended her track career. In our case, if we didn't have hard data tracking her before and after performance levels, we may not have ever noticed a difference. How many people who aren't competitive athletes are walking around with 10% degraded pulmonary function and just didn't notice?

The idea that the earth is flat is a fringe belief. No evidence (that hasn't been disproven) exists to suggest that the earth is flat. What progress is being made by giving flat earth ideology equal footing? If any idea—even those with no evidence to support them—are published in authoritative texts as possible truths, then how can anyone trust those texts? If I convince enough people that the center of the earth is filled with spaghetti (of course it is, that's why the moon is made of cheese! To go on the spaghetti!) does that deserve equal footing on Wikipedia? Of course not.

I can't speak for the UV team. My 2C on how I would treat the PEPs: If there is an accepted one, and implementing it doesn't go too strongly against your competing design goals, do it for compatibility. This does not imply that the PEP is driving your design, or required to make your software. It is a way to improve compatibility.

Hard disagree. Burning something alive in a slow and agonizing death for zero purpose other than cruelty is nowhere near the same thing as near instantaneously killing an animal for animal husbandry purposes.

Could we do better or have better practices? Sure. Is there an argument for not eating meat at all? Sure.

But if you were going to die you would have a lot bigger problem being slowly roasted alive versus instant brain destruction.

1. They are calling a wildfire an "extreme weather event" which is dubious as weather is only a contributing factor here

2. Of that $100 billion, $60 billion is from the LA wildfire, so this number is extremely outlier driven

3. There are no inflation adjustments or tests of statistical significance in their claims that damage from extreme weather is rapidly increasing over time

It should be used exactly so you don't have to drop your pants in public to prove your sex, e.g. to access single sex spaces like sport categories. But that requires the field to be filled accurately by whoever issues the document. The fact that this field was not filled accurately led some organisations (most famously World Boxing, but not only) to resort to sex testing. Facing such choice (either accurate data in readily available government-issued ID or SRY test around every corner), I'd prefer the paper document contained reliable data.

It's a pretty sad reflection of the times that there's a need to create a throwaway account to talk about long COVID symptoms, but this is a good personal anecdote to draw attention to what's likely happening. In my case, I only caught covid once - somepoint last year just before I would've gotten the updated booster. It took me well over a year to stop having acute pulmonary issues, and my lung performance is down year over year (measured during high intensity training) even though I finally feel no differently at baseline than I did before I caught it.

Most people don't exploit the full capacity of their bodies and so would never notice, which is essentially the point OP is making. This disease very likely ravaged the 20% claimed, but the vast majority may never know because they're just never pushing their bodies hard enough.

There are certain materials that aren't just white but also specifically radiate heavily in IR bands that the atmosphere is particularly transparent to and so can actually stay sub-ambient temperature while in sunlight. See, for example, https://onlinelibrary.wiley.com/doi/full/10.1002/eom2.12284

No surprise this is written by a conservative think tank guy with a focus on an economic policy agenda. Stay tuned for "actually, the NLRA is bad for workers" and "really everybody should have the right to work at a business that doesn't meet OSHA requirements" and "your 401k depends on stock prices, so don't you dare raise the corporate tax rate."

I very sorry that banks lose out when somebody gets a fixed rate mortgage and then rates rise. "If only everybody had adjustable rate mortgages" doesn't seem like a win to me.
