Hello! Sorry for the delay, I thought the thread was indeed dead. Hehe.

Maybe you are right about clamp(), but I still think it's only available through “obscure” means if I may say so. So yeah, a clamp utility would help.

On performance and DevTools:

Take this site for instance: https://bentonow.com According to Chrome’s coverage panel, 75% of the CSS is unused on the homepage. I’ve seen this pattern on a lot of Tailwind sites. With native CSS, it’s easier to serve styles just-in-time, alongside related components. That way, users aren’t forced to download styles for pages they’ll never visit. HTTP/3 makes this kind of modular CSS much more viable.

As for DevTools, I find them much lighter, simpler, and faster to use with native CSS compared to functional CSS like Tailwind. The DOM is cleaner, and the cascade panel is far more intuitive to explore. Selectors actually mean something and reflect real relationships between content elements.

If you want to compare, you can have a look at https://ecss.info/en and then check out any Tailwind site in the DevTools.

Happy to chat more if you’re interested!

I'm not the OP, but from what he said I can tell you two things:

1. He is using computers to solve other peoples problems, and they are similar problems so all the code looks the same, and

2. He is NOT using computers to solve his own problems. Every top notch software engineer I've met does not write the same code more than a few times, because doing repetitive stuff is something a computer should be doing.

One of the best tools for peer review is forced rankings. Asking questions about a peer's performance will typically get you either a bland non-answer or a heavily biased opinion that has little to do with the specific performance you're actually asking about - it's just the nature of interpersonal relationships, we don't view Bob's communication skills as a separate thing to be analyzed independently of our opinion of Bob as a person. Forced rankings where a person's performance at one specific task must be compared to multiple other peoples', and ties are not permitted, gives us the freedom to disassociate the skill from the person and treat it more objectively. It's also more easy to compare responses from multiple sources. Bob may be a nice guy who is always happy to lend a hand, but if he is still the last person anyone on the team would go to for an explanation of a tough technical concept, you know what he needs to work on.

> There is zero financial incentive for a physician to prescribe a statin.

Well, doctors make money when they prescribe drugs: Patients will make more doctor visits when they are on prescription medications than if they are not.

> The data showing benefit...

The reason for the benefit is not fully understood. The argument is that the benefit comes not from lowering cholesterol but from reducing inflammation and stabilizing plaque. The medical community has no incentive to research this because they are raking in money, and any further research could only slow down the gravy train at best.

I’ve been a software engineer for 18+ years, starting with C++, MFC, and ATL COM, and have since moved into mobile development across iOS, Android, and now AI integration using CoreML, TensorFlow Lite, and ChatGPT APIs.

This article shares lessons from my journey—from debugging DirectShow filters to embedding AI models into Apple Watch apps. My goal is to help others transitioning from traditional development into modern mobile AI.

Would love to hear your feedback or hear from others walking a similar path.

From the linked Hackaday article:

> If you don’t want to kill flies, wasps, bees, or other useful pollinators while eradicating the tiny little bloodsuckers that are the drone’s target, you need to be able to not only locate bugs, but discriminate mosquitoes from the others.

> For this, he uses the micro-doppler signatures that the different wing beats of the various insects put out. Wasps have a very wide-band doppler echo – their relatively long and thin wings are moving slower at the roots than at the tips. Flies, on the other hand, have stubbier wings, and emit a tighter echo signal. The mosquito signal is even tighter.

Fascinating engineering! Doesn't seem like it would be possible but it apparently is. There's also more visuals at about 17 minutes in the video embedded in that article, the signatures seem fairly distinct.

I had some faith this time as I saw a good handful of readers opening the email just moments after I'd posted the newsletter out!

And while I figured Hacker News would be a coin flip, for other sites that show link previews, I was optimistic that the cartoons would encourage a click, too. In a time where many writers are using soulless AI-generated poster images, just putting in a token effort to do something original goes a long way.

That puts you at just over 5W average on a 61whr battery. I find that very hard to believe. 5W is achievable if you drastically limit the CPU governor, physically disable the mic/camera, using a chart-topping power-efficient SSD, all while actually doing nothing. Just a single YouTube video in a single firefox tab will bring you up to at least 10W.

yes, it makes sense in some situations, because if all you want to do create a small batch (.BAT) file of a few lines, and you are a careful / good typist, the COPY CON method can be a lot faster then firing up your favourite editor, even a fast one like vim, to create the file, save it and exit.

and the same applies for UNIX.

I am working on DataGrid Toolkit. Based on my experiences building and selling (Excel like) data grids, people always look for your data grid, "but can it do this"? With DataGrid Toolkit, a developer can choose his own building blocks/modules and make a more Excel-like data grid, or make a more DataTables style traditional paginated table. The toolkit is headless and stateless by design and comes with different renderers. Canvas, html or some hybrid. It is written in Typescript and the data store is in Rust/Webassembly.

Sorry, but this is nonsense. I'm not talking about photos, but about graphs, line art, tables. Using PNG you can create real small (in filesize) images, like 10-30 kilobytes. The size of the image (dimension) often doesn't matter that much. You can create the same image (black on white or line art with three or four colors) and resizing (less pixels) it won't make much of a difference in file size, nothing significant.

I cannot believe that publishers create small pictures because bigger pictures means that their book will be deleted later on. That argument seems far fetched.

We’re building a P2P protocol that replaces capitalist value systems with contribution-based logic. It measures value through actions, prestige (trust), and system response—not profit.

The model is mathematically proven to converge to π, symbolizing natural harmony. So people can choose it not as a dream, but as a rational system for real well-being.

I have a few prospects lined up.

I'm actually planning on doing a second masters from a slightly more prestigious university with a more theory-heavy degree [1], but it's nice to at least have an official graduate degree now. Hopefully it helps me find work a bit quicker, and if nothing else it's just kind of fun to pile up degrees.

No one in the chain of comments you are replying to has mentioned anything about Google, and on HackerNews you will find the majority sentiment is against spying in all forms - especially by Google, Meta, etc.

Even if we interact with your rhetoric[1] at face value, there is a big difference between data going to your own elected government versus that of a foreign adversary.

Bit of a mess of an article IMHO.

Intelligence agency staff leave their roles, just like anyone else does. Unregulated? They're as regulated as the rest of us. Then you have the article casting aspersions on them for doing so, it must be about money and malign foreign influences. Of course foreign states use proxies; so does the UK. Why's that even mentioned as if it's implying ex-intel staff are the proxies - which as far as I'm aware, they're not?

Should we ban these people from working again, or ensure they only flip burgers for the rest of their lives for daring to leave the public sector?

There’s the problem. It wasn’t a political ad for Al Gore, it was published 8 years before he ran. It just so happened he was actually interested in improving things and leaning on smarter people for policy, but that made half the country go “Eeeewww… facts! Elitism!! we want someone dumber we can have a beer with for president!” That was literally an argument in the 2000 election: who would you rather drink with. Then GWB put on his yokel hat and yokel accent and dumbed it down so that people wouldn’t be scared. Instead of voting for someone with a plan, they voted for some rich cokehead fail-son from the Bush dynasty because he seemed more “of the people”. But Al Gore takes the flak for trying to raise awareness. Unbelievable how dumb this country is as a whole. And 10x dumber now that the current POTUS is unwriting history at rocket’s pace.

Ah, but that’s the thing it’s not compression it’s tension. Try hanging the same steel cube from the ceiling with a scrap of paper and things get decidedly more difficult.

Just passed 20k (21k) users across 800 diff unis this past month. Super excited, thought i'd share. We applied to YC last year when we only had a few hundred users across our alma maters (Berkeley, Princeton, Dartmouth, Long Beach) and it was a v1.0.0, so we've come a long way through scraps and word of mouth.

We're launching our v2 pretty soon as well, just passed 2800 registrations for it. If you're interested, students eat free, professional version coming soon (must have a work email).

Cheers

Performance per watt is not far at all from M4. The Ryzen AI 9 HX 370 actually beats a M4 Max in e.g. Passmark per Watt (652 vs 625), and it's not much behind in other benchmarks.

With some tweaks, it can also be silent. Good ThinkPads are not far from the user experience delivered by the latest MacBooks, and they have the advantage of running free software and x86_64.

According to the article, the evil Google has made life harder for affiliate marketing industry, SEO industry, alternative medicine sites... Well, Google has certainly made quite a few unpleasant things, but mentioning these as examples makes it hard for me to sympathize the author's case.

(Added:) Allegations of Google's manipulating the search results to influence voting behavior are much more interesting.

It was the least I could do to help the discussion, as I’m not really knowledgeable enough about Yellowstone ecology personally to have a nuanced discussion with you or others in this thread, so I have to find other ways to contribute positively to help us all catch where catch can by enabling debate through proper context.

You’re welcome, and thank you for your response on the points for the benefit of me and the thread, as it was beyond my ken.

Built a bespoke loyalty points system for a chain of gas stations back in 2020. Thought at first it would be a one time deliverable and then I could move on with my life. Cut to today and I'm trying to launch it into it's own platform.

Nothing much to show other than one client, but I'm on the cusp of charging them monthly vs getting paid by the hour.

You are talking about a very different product :) I have spent over a year making sure everything works for many languages. The whole point is to have one interface, for all my languages, big and small.

Additionally, please try it out before assuming they’re just claims. I’ve been using it daily for 3 months in 18 languages (roughly one from each major language family), and been in pretty constant contact with native speakers.

True I cannot vouche for all 120 languages, and sure there is the occasional error in the lower resource languages. However, I have put in a lot of work to make sure I have a representivie sample, and the errors are currently well within an acceptable range — and I’m working hard to improve them!

Comments about SLS miss what’s happening. SLS is inefficient and wasteful, but human spaceflight is not what’s getting cut at NASA. Instead, very productive current and future science missions are getting killed, in defiance of Congress [1].

Until this year, NASA was the world leader in space science. We’re pushing out the experts who build and operate astrophysics missions like Hubble, Chandra, JWST, Kepler, TESS, Swift, and many more in planetary and heliophysics. This is a loss of capacity that will set the US back a generation.

The private sector is irrelevant here: SpaceX and friends don’t do scientific research.

Anecdata but Kiro is much, much, much, much easier to put through corporate procurement compared to its peers. I'm talking days vs months.

This is not because it is better and I've seen no inclination that it would somehow be more private or secure, but most enterprises already share their proprietary data with AWS and have an agreement with AWS that their TAMs will gladly usher Kiro usage under.

Interesting to distinguish that privacy/security as it relates to individuals is taken at face value, while when it relates to corporations it is taken at disclosure value.

> businesspeople

Well, there's your leading qualifier. Covid taught us that businesspeople can do their work on an iPad with Google Docs if they had to. It's not much of a surprise to anyone that they can do their work on a Mac with a souped-up iPhone processor.

My shock with Apple Silicon is how it collapses with non-browser-oriented tasks. The moment I stop watching YouTube it's like I'm back on Linux in 2008 again, trying to run everything through a Windows VM. My old Pro Tools plugins? Gotta use a VM, Rosetta won't work. A modern OpenGL program? Gotta wrestle depreciation flags to compile it. Even my old Homebrew casks had to get rewritten because Apple Silicon had to switch stuff around again.

By the time people insisted "try the M2 for a few weeks!" I was already dailying NixOS. MacOS is continuing the frying-pan-to-fire arc it started ever since 10.14.

I merged support for JavaScript object "shapes" in my Nova JavaScript engine last week; now I just have to clean up some of the ugly parts of the API (and maybe do some performance adjacent changes), and then it's time to use the shapes for property lookup caching!

This is one of the most important performance features in a JS engine, as without shapes property lookups would be terribly slow. I'm looking forward to getting this working.

We don’t have enough experience with the SEN5x yet to give an opinion but it’s definitely a good sensor.

It might be better than the Plantower but on the other hand we know the Plantower really well now after 10s of thousands of units going through our test chamber. This allows us to tweak the Plantower to really good performance.

You can also do this via "netcat", running the commands below in a terminal.

Receiver (listening to port 31337):

`nc -l -p 31337`

Sender (connecting to receiver IP):

`nc <receiver_ip> 31337`

Want to send a message to the receiver:

`echo "Hello from Kocial" | nc <receiver_ip> 31337`

== if you want to send a file ==

Receiver:

`nc -l -p 31337 > hackernews.pdf`

Sender:

`nc <receiver_ip> 313337 < hackernews.pdf`

That's like saying when you grow your own tomatoes you're dependent on the weather or your capability to deal with said weather. That is true. But it misses the point. When you grow your own tomatoes and the store sells only a certain bad tasting kind, suddenly wants to increase the price by factor 10 or stops selling tomatoes at all, then the value of growing it yourself shows. And they are dependent on the weather just like you.

If you self host, you're dependent on things sure. But the point isn't to reach some hypothetical perfect state of independence, the point is to get the flavour you want, not have to deal with them changing their business model, and so on.

The reason I self host my webservers is because my webhoster decided to charge a premium for SSL certs. So much in fact that for the cost of one cert per month I could run a webserver for a year.

Then I had my mailservers noster taking decisions I didn't like, so again I went and self hosted.

Some of those things are running for a decade now and I have yet to experience the catastrophic events you mention. Sure you need to do your due diligence and know your craft, but at least I am ot affected by someone changing their business model or deciding it isn't profitable anymore.

Does anyone know if this tech (or Iroh) is suitable for real-time networking for games? Basically, once connection is established, what's the overhead on top of UDP in terms of latency and bandwidth?

Edit: after digging a little, Iroh uses QUIC which looks like a reliable, ordered protocol as opposed to the unreliable, unordered nature of UDP which is what many games need.

Now what I'd love to figure out is if there's a way to use their relay hopping and connection management but send/receive data through a dumb UDP pipe.

Respect, but this is kinda the hard way - I just plugged mine (dumb machine, not smart) in via an energy metering plug, and when energy use drops to less than 10W for more than 2 minutes, it’s done - very simple homeassistant automation. Convenient for me as the machine is 500m from the house.

Oh yes, Next.js is on my permanent blacklist of ”I won’t take a job if they use it”. It’s truly one of the worst maintained software I’ve ever used, they break stuff constantly, completely without awareness.

Show HN: Open-source physical rack-mounted GUI for home lab
by mmajzoobi | 2025-07-27 21:13:52+00:00
I have realized that a lot of people nowadays self-host services and set up home labs with mini racks.

One major pain point I have come across personally is to quickly get health status from self-hosted services and machines, and have the ability to headlessly control my Raspberry Pi inside a mini rack.

So It got me thinking about building a built-in GUI that users can easily add to their Raspberry Pi nodes in their (mini or full) racks or elsewhere.

I have previously designed this GUI for an open source project I have been working on (called Ubo pod: github.com/ubopod) and decided to detach/decouple the GUI into its own standalone module for this use case.

The GUI allows headless control of your Raspberry Pi, monitoring of system resources, and application status.

I am designing a new PCB and enclosure as part of this re-design to allow for a new form factor that mounts on server racks.

I am recording my journey of re-designing this and I would love to get early feedback from users to better understand what they may need or require from such a solution, specially on the hardware side.

The software behind the GUI is quite mature (https://github.com/ubopod/ubo_app) and you can actually try it right now without the hardware inside the web browser as shown in the video:

The second Opinion unit, for outside submissions, is the Amazon reseller concept applied to news. It's why you can't buy anything important on Amazon any more.

There are very few American newspapers left that have actual reporters in the field. The New York Times and the Washington Post are almost the only ones left. The result is that most stories begin from some press release. Look at the Washington Post right now.

- "Trump, European Union reach trade deal with 15% tariffs" - from a press release.

- "Israel to let more aid trucks into Gaza, under pressure over hunger crisis Israel said..." - press release

- "Denied federal flood relief, a Maryland town is left on its own" - actual reporter coverage of regional news.

- "Trump’s imaginary numbers, from $1.99 gas to 1,500 percent price cuts" - desk work, rehash of existing info.

For most other newspapers, it's even worse. Few if any boots on the ground.

Not sure if meant seriously or sarcastically. But it seems like a pretty reasonable option to me. Yeah, commercial air travel is super cheap and fast these days, especially for very far destinations. But it has its headaches and downsides too, and plenty of people choose to drive for various reasons even if it's slower and more expensive.

If you have the skills and equipment, it might well be worth the $900-$1700 or whatever. You're also potentially taking 3 other people, and luggage, and avoiding the costs and headaches of big commercial airports and airlines, plus TSA etc.

I've been learning PassKeys and WebAuthn.

Getting together a very simple server (PHP), and very simple clients (UIKit and SwiftUI), and will publish a blog series on it (sort of like this[0]), once I get more used to it.

I need to really get comfortable with it before I do that, though.

It's fairly simple to keep these devices isolated and if you have a decent firewall, you shouldn't have much to worry about. Keeping them in a separate, internet-only VLAN with peer to peer isolation is typically the standard protocol. That said, in a lot of cases, even keeping the isolated doesn't resolve any privacy concerns. Also, with some devices, you have to open up mDNS.
