I agree that libraries are a thing, all problems in CS can be solved with a layer of indirection, etc. I also have no issue with AI-gen projects if they're good.

In this case, they posted a README full of nonsense diagrams, didn't fix the broken characters in their UX, and breezed over the complexity of the dependencies (ESP-CSI is very cool but requires specific hardware, with two ESP devices and external antennas). Feels sloppy.

> Instead of getting cheap Chinese made clothing for $5, you now get to pay Walmart $17 for the same thing.

Right... but now that is (arguably) cost competitive with American labor and manufacturing. Or at least it's more cost competitive than it otherwise would be.

I mean this is kind of the price of putting what we say first. Want higher minimum wages, higher environmental standards, unionized labor, benefits/healthcare, lunch breaks, etc.? We will have to pay more, and we should, for those things.

You're touching upon a very nuanced point of identifying the true "intent" behind these words. Do you think the way these models are trained should be different to correctly map the potential intent vs the true meaning?

like your example, "the meeting is at 3pm", _we got enough time_ intends something else with "the meeting is at 3pm" _where the hell are you?_ intends something else. It is not so obvious to get that intent without a lot of context (like, time, environment, emotion etc.)

You must not be using professional saws then. An electric version of a professional Husqvarna or Stihl (only as an example) with the battery weigh the same as a gas version with gas and oil in the tank.

I would argue it’s even more obvious that you have not used one or at least in a professional capacity as you are still looking at 90-100dB running an electric chainsaw.

If there's one thing I definitely don't want AI in the middle of, it's communication with other people. The potential for misunderstandings due to hallucination in summaries, both on my end and the recipient's, scares me. There were some pretty bad examples with Apple News.

Accuracy matters, especially when communicating with customers or between managers/employees, and I can imagine many kinds of scenarios where this goes wrong.

That certainly raises questions.

I am bemused / irked / saddened by the state of nutritional science research. I am convinced that the classic "food pyramid" that was pushed for years was a bad idea, but now guidance on what to eat seems to have split into various warring factions.

Some say that we should severely limit or even avoid meat. Their words look correct on the surface, but I notice their science seems based on "meat" pretty generically. There doesn't seem to be any accounting for eating high end grass fed beef from an organic market vs. low-end beef from a gas station. Does it really make no difference?

Another faction recommends eating meat freely, with no distinction as to type or quality. Another insists on the highest grade meat but then also discourages dairy. Another recommends high quality meat and no vegetables.

I would think that it would be, by now, more straightforward to determine what really makes most sense to eat. I guess (nearly?) everyone seems to agree that adequate water is good and too much sugar isn't.

I think it's all about change management

a whole month put you in the "if you don't have the resource to automate it, it's still doable by a human, not enough to crush somebody, but still enough to make the option , let's automate fully something to consider"

hence why it's better than a week or a day (it's too much pressure for small companies) better than hours/minutes/secondes (it means you go from 1 year to 'now it must be fully automated right now ! )

a year or two years was not a good idea, because you loose knowledge, it creates pressure (oh my.... not the scary yearly certificate renewal, i remember last year we broke something, we i don't remember what...)

A month, you either start to fully document it, or at least to have it fresh in your mind. A month give you time to everytime think "ok, we have 30 certicates, can't we have a wild card, or a certificate with several domain in it?"

> Perhaps it's time to go with another method entirely.

I think that's the way forward, it's just that it will not happen in one step, and going to one month is a first step.

source: We have to manage a lot of certificate for a lot of different use cases (ssh, mutual ssl for authentification, classical HTTPS certificate etc. ) and we learned the hard way that no 2 years is not better than 1 , and I agree that one month would be better

My "dumb" is what got you into this situation. I notice you left Denmark off that list. Wonder what's different there? Perhaps if your center-left / center-right parties realized, like anyone with a brain did well over a decade ago, that mass third world Muslim immigration into Europe is the stupidest political idea of the 21st century so far, you wouldn't be in this position. Perhaps if you realized your political foot gun is the real threat here, and not your own citizens who oppose it, you wouldn't be worrying about a "hitler gets elected again" scenario.

I'm not sure if you're arguing in good faith, but assuming you are, it should be pretty self-evident why you wouldn't generate the certificate dynamically each request: it would take too much time to do so, and so every request would be substantially slower, probably as slow as using Tor, since you would need to ask for the certificate from a central authority. In general it's all about balance, 1 month isn't necessarily better than 1 year, but the reduced timeframe means that there's less complexity in keeping some renovation list and passing it to clients, and it's not so short to require more resources on both the issuer and the requester of the certificate.

> Perhaps it's time to go with another method entirely.

What method would you suggest here?

It's hard to tell how your commment was a sincere response rather than derision for anyone using or targeting Windows. There was nothing technical. Here's a technical response:

There's nothing 'hidden' about dotfiles on UNIX-likes, unlike on Windows where, as I mentioned, there is such a thing that is exposed by the OS filesystem API (it's a normal attribute and can be straightforwardly set/unset with right-click -> Properties; not an extended attribute which refers to a very specific thing).

That files and directories beginning with a full stop are hidden in `ls` was openly acknowledged as a bug[1] in the original implementation, that gave rise to 'a bad precedent'. Ergo all the repeated gnashing of teeth (see this very article) by UNIX-like consumers who end up noticing the dotfiles anyway, because a significant plurality of people use a variant of `ls -la` for the utility of its tabular output.

I think the criticism here is not that the article is incomplete ("not exhaustive") but rather that it makes several fundamental mistakes and doesn't actually describe Big O. It describes a "pop culture" version of Big O, which is not Big O, but calls it Big O.

It's not useless, and a lot of care seems to have gone into it, but ultimately it's a lay person explaining something they don't firmly grasp, and making a couple of serious mistakes in the process.

I love the presentation itself though!

The reason the web is a rotting carcass is not because of the way the web is architected, it is because a lot of people's livelihoods depend on making it as rotten as possible without collapsing it entirely.

From advertising companies, search engines (ok, sometimes both), certificate peddlers and other 'service' (I use the term lightly here) providers there are just too many of these maggots that we don't actually need. We mostly need them to manage the maggots! If they would all fuck off the web would instantly be a better place.

I guess the equivalent would be compiling rm without the '--no-preserve-root' option?

Realistically I know a professional arborist. Not only does he have all the safety equipment on his saws, all his crews have full PPE available and use it. The only piece of safety equipment I've ever seen that was dubious is the "sawstop" for table saws, primarily because it false triggers so often.

> Stallmans usage of free software is exactly the same as the rest of the worlds open source.

Not at all, that's why there are separate terms! GNU has an article that's worth reading: https://www.gnu.org/philosophy/open-source-misses-the-point....

I'll point out a very practical case. I was once-upon-a-time interested in Nostr, because I liked the relay idea. I looked for a client, and found one called Amethyst. When I installed it, I saw the author had inserted a pop-up on load that had me agreeing to his "Terms and Conditions" for using "the service". But the author had no service...he was worried about his liability if I posted something. Stallman saw this coming! From the article above:

> Third, the criteria for open source are concerned solely with the use of the source code. Indeed, almost all the items in the Open Source Definition are formulated as conditions on the software's source license rather than on what users are free to do. However, people often describe an executable as “open source,” because its source code is available that way. That causes confusion in paradoxical situations where the source code is open source (and free) but the executable itself is nonfree.

> The trivial case of this paradox is when a program's source code carries a weak free license, one without copyleft, but its executables carry additional nonfree conditions. Supposing the executables correspond exactly to the released sources—which may or may not be so—users can compile the source code to make and distribute free executables. That's why this case is trivial; it is no grave problem.

And this is _exactly_ the argument the author of Amethyst makes, check out how he reasons through the additional restrictions: https://github.com/vitorpamplona/amethyst/issues/378

His reasoning is squarely in this weird zone the Stallman wrote about:

> I am confused. Why are we mixing the license with the terms of use? These two files are separate legal matters. The Privacy is used by the Play Store to manage the distribution of the executables. The MIT license relates to the source code only.

> In other words, the MIT license removes any author liability from the misuse of the code. But when the author is also providing the system as binaries (which is an additional service in every jurisdiction I know of), there are many other legal issues that the source code license won't cover.

> And I don't know about you, but I am not comfortable allowing people to use the Play Store version or the FDroid version for these activities written in the Privacy statement. Most of them are local crimes that should not happen anyway.

> This has nothing to do with the source code license, which people can still download, compile and use in nefarious ways.

Anyway, my point is, in practice, there's a million ways to water down "open source" to remove user freedoms, and the value of Free Software is that it keeps the focus in the right place to avoid falling victim to those tricks.

> How can you come from a Svelte/Framework background without first understanding basic JavaScript?

The charitable take: many of the younger f/end devs don't really know that $FRAMEWORK gets turned into Javascript. I've worked with one dev in the past 5 months who did not realise that Javascript is the underlying target of "compiling" their react project.

The uncharitable take: This was vibe-coded from a set of specs.

> It's bringing up an entirely unrelated topic as some sort of "gotcha"

Expecting people to be consistent, and treat similar situations similarly, is not a "gotcha". Challenges like this are raised exactly to hold people to their own standards and question whether they are really okay with the consequences of what they just said.

The topic described is not at all "entirely unrelated". There is a clear natural category which encompasses both tariffs and cigarette taxes.

Walmart is not just a supermarket. They sell a wide variety of goods—and since my wife was in the wholesale costume industry for a while, I happen to know that they tend to have retail margins of roughly 50% (or at least, they did 10 years ago).

Walmart does tend to operate more on volume than margin, but they're definitely not stuck with grocery margins on everything.

> If I open too many tabs in Chrome I can feel the bottom of the laptop getting hot, open a YouTube video and the fans will often spin up.

Change TDP, TDC, etc. and fan curves if you don't like the thermal behavior. Your Ryzen has low enough power draw that you could even just cool it passively. It has a lower power draw ceiling than your M1 Pro while exceeding it in raw performance.

Also comparing chips based on transistor density is mostly pointless if you don't also mention die size (or cost).

Guys, it's been over for a while now. And I mean decades... This is just one of the next steps in the path that's been laid out in front of us since the general population reached critical mass on the Internet and the ruling class (politicians, the media, corporations...) went all in on exploiting them for money and power. If we don't radically change the underpinnings of how the entire system works, we're in for much worse than this.
by bloomca | 2025-08-26 13:32:40+00:00
What do you think is better? The web is indeed questionable, but it is literally the best we have, it is still reasonably simple to deploy a web app.

Desktop app development gets increasingly hostile and OSes introduce more and more TCC modals, you pretty much need a certificate to codesign an app if you sideload (and app stores have a lot of hassle involved), mobile clients had it bad for a while (and just announced that Android will require a dev certificate for sideloading as well).

edit: also another comment is correct, the reason it is like that is because it has the most eyes on it. In the past it was on desktop apps, which made them worse

I don't think so. Mbed used to have a nice one for all the boards that support Mbed, but that's dead now.

Looks like Zephyr has an extremely comprehensive list: https://docs.zephyrproject.org/latest/boards/index.html

Doesn't include prices though, and it's really too comprehensive - it seems to include lots of boards you can't actually buy. So maybe not very useful for finding good boards.

Since the advent of LetsEncrypt, ACME, and Caddy I haven't thought about SSL/TLS for more than about an hour per year, and that's only because I forget the steps required to setup auto-renewal. I pay nothing, I spend a tiny amount of time dealing with it, and it works brilliantly.

I'm not sure why many people are still dealing with legacy manual certificate renewal. Maybe some regulatory requirements? I even have a wildcard cert that covers my entire local network which is generated and deployed automatically by a cron job I wrote about 5 years ago. It's working perfectly and it would probably take me longer to track down exactly what it's doing than to re-write it from scratch.

For 99.something% of use cases, this is a solved problem.

It might be harder to host at home, but only for network reasons. It is perfectly straightforward to use letsencrypt and your choice of acme client to do certificates; I really don't think that's meaningful point of friction even with the shorter certificate lifetimes.

I wouldn't call myself an expert arborist, but I cut the firewood that provides all my heat in the winter. The safety features (mainly the goofy guard they put on the end of the bar) are good if you're a homeowner cutting some shrubs a couple times a year, but you have to take that off to drop a tree or cut pieces wider than your bar, so they aren't practical for serious work.

Fortunately, a chainsaw isn't a very dangerous tool, since it stops as soon as you release the trigger. The danger in dropping trees is from the tree itself: having one fall the wrong way or crack loose at the base before you expect it. I don't drop anything large when I'm working by myself, for that reason. I've been mildly injured by some surprisingly small trees, when something happened to bounce where I wasn't expecting.

It is likely the hardware effiency of their chips. Apple SoCs running industry-standard benchmarks still run very cool, yet still show dominant performance. The OS efficiency helps, but even under extreme stress tests like SPEC, the Apple SoCs dominate in perf & power.

See Lunar Lake on TSMC N3B, 4+4, on-package DRAM versus the M3 on TSMC N3B, 4+4, on-package DRAM: https://youtu.be/ymoiWv9BF7Q?t=531

The 258V (TSMC N3B) has a worse perf / W 1T curve than the Apple M1 (TSMC N5).
Ask HN: Are math contests more about attracting top teachers than anything else?
by amichail | 2025-08-26 13:34:01+00:00
High school math contests seem to benefit only a few gifted students.

But maybe their real purpose is to make teaching math more appealing to very smart teachers.

This, in turn, makes the school look good in the community.

And perhaps those gifted students would have done fine without the contests anyway.

In other words, high school math contests mostly benefit smart math teachers and schools that want a reputation for academic excellence.

For most students, math contests don’t provide much benefit if any.
Looking for a Growth and Marketing Cofounder for Lurnix (Equity-Based)
by fredagbona | 2025-08-26 13:34:03+00:00
Hi everyone

I’m Freddy, a software engineer and mentor. Over the past years, I’ve personally mentored 500+ self-taught devs, students, and career switchers. I kept seeing the same problem: people don’t fail at coding because they lack talent they fail because tutorials, bootcamps, and courses throw everyone into the same rigid path.

That’s why I started building Lurnix → an AI-powered learning coach that adapts tech training to each person’s brain, pace, and goals.

7 days to master the basics

30 days to build real projects

Supported by an active Discord community

And soon: human coaching sessions inside the app

We already have early traction (a waitlist, first testers, an engaged community) and I’m pushing hard to make Lurnix the go-to platform for learning programming fast and effectively.

Who I’m Looking For I need a cofounder focused on growth & marketing to join me:

You’re obsessed with distribution, storytelling, and user acquisition

You know how to make noise on Reddit, Discord, LinkedIn, X and turn attention into growth

You’re hands-on, scrappy, and excited to build in public

You believe in the mission: make learning to code faster, simpler, more personal

This is an equity-only role at first (I can’t pay a salary yet). But you’ll be a true cofounder, shaping the business and owning the growth engine from day one.

Why Join Now You’ll be early: co-ownership of something that can scale globally

You’ll work directly with me (tech/product founder) and help shape Lurnix’s future

Together, we’ll target both international markets (US, EU) and fast-growing African edtech ecosystems

If this resonates, DM me or drop a comment. Let’s chat.

Something is wrong with power governor then. I have an opposite experience, was able to tune Linux on a Core Ultra 155H laptop so it works longer than Windows one. Needed to use kernel 6.11+ and TLP [0] with pretty aggressive energy saving settings. Also played a bit with Intel LPMD [1] but did not notice much improvement.

One caveat here is that the author of the article posted it here in HN for comments -- it's not that someone else did, and this is unfair because HN was never supposed to take a look, etc. They expected a review, otherwise they wouldn't have posted it here.

HN is not an audience of laypeople (mostly) and will critique the article with a different mindset than a novice that might be impressed by the visuals (which are impressive).

So I think the reaction is both to be expected and reasonable: HN will critique how correct the explanation is, and point out the mistakes. And there were a couple of fundamental mistakes due to the author not being a subject matter expert.

There is no intent in words in and of themselves. Intent always comes from something specific tied to neural syntax, which is lost in words. That's an illusion. There is intensionality, which is different, which is what you're actually talking about. Intensionality is vague, it's not meaningful without context. The problem automating words is AI can't solve the conduit metaphor, which is the idea the words alone code meaning. They can't. This is the achilles heel of AI.
