It’s true for me. I need a portable workstation more than a mobile laptop, as long as it survives train travels (most have power outlets now), moving between buildings/rooms or the occasional meeting with a customer +presentation it is enough for me.

But I can imagine some people have different needs and may not have access to (enough) power outlets. Some meeting/conference rooms had only a handful outlets for dozens of people. Definitely nice to survive light office work for a full working day.

For the past like 30 years I feel there's never been a time some commercial Mac program hasn't filled a simple niche. I remember someone last year posting a Show HN for an ffmpeg wrapper for Mac with a limited feature that focused on transcoding and made $9k in the first 4 months.

Or in the late 90s when there was a commercial program that allowed OS 9 to show real-time window previews while dragging rather than merely showing the window border outline.

> I can do banking and otp at home with a 100 Euro phone that I use only for that.

That doesn't solve anything, though. If Google revoked your Google account and refused to open a new one, you'd be SOL - you'd either have to buy an iPhone, or move banks until you find one that gives you a physical TOTP (since many just have apps already, but those apps don't run unless downloaded from the Google or Apple stores).

There's a direct line from mandating seatbelts to mandating developer certificates. If you accept in one domain that it's legitimate for power to reduce freedom to protect people from themselves, you'll accept it in every domain.

Look: in order for a mandate to be justifiable, it needs to at least provide superlinear benefit to linear adoption. That is, it has to solve a coordination problem.

Do seat belts solve any coordination problem? Do they benefit anyone but those wearing them? No. Therefore, the state has no business mandating them no matter the harm prevented.

A certain kind of person thinks differently though. He sees "harm" and relishes the prospect of "protecting" people from that "harm". They don't recognize the legitimacy of individual bad decisions. The self is just another person trying to hurt you. This kind of person would turn the whole world into a rubberized playground if he could.

> The subscription basically offsets the cost of needing to replace the seats more frequently when the heating is enabled

I never heard of car-manufacturers periodically replacing seats within warranty because of the wear of the material, regardless of being "more frequently" or not. This sounds like a massive oversight in product-design.

Of all the cases I know, the customer had to bear the cost of such "wear and tear" cases.

Two root comments (so far) are focusing on YouTube, but the article claims most of the AI was done by Will’s team, using AI to convert stills to video:

> The video features real performances and real audiences, but I believe they were manipulated on two levels:

1. Will Smith’s team generated several short AI image-to-video clips from professionally-shot audience photos

2. YouTube post-processed the resulting Shorts montage, making everything look so much worse

You can see the side-by-side [1] of the YouTube post-processing, and, while definitely altering the original, isn’t what’s causing most of the really bad AI artifacts.

Most of what YouTube appears to be doing is making it less blurry, sometimes successfully, and sometimes not. And, even with that, it is only done on Shorts.

I set up one to run Frigate [1] to detect motion over my several security cameras and send me notification emails with still images and video clips attached. It works well, and I hate the idea of sending my private videos to the cloud for processing with usual security camera setups.

This is based on the false assumption that the free market solves every problem.

But the reality (which was correctly identified by Adam Smith himself) is that the effort required to enter a market can sometimes be so high, that we practically end up with oligopolies, see mobile OSs. They require a network effect to make sense, so the entry cost is not just developing the product, but also to somehow convince basically every other player to consider you a target platform - which is a cyclical problem that you can't just bootstrap yourself into. Even Microsoft failed at it, even though they were paying hefty sums to companies for apps working on their OS.

Another instalment of HN thread where people try their best to pretend that "security" does not come with "enforced, ideally at hardware level, inability to run random code" for 99% of phone users.

Here a tip: you won't solve the problem of security by just whining about corporate interests (which is a real concern) and NOT proposing a better solution that works for an average tech illiterate, very socially engineerable person trained to ignore every warning screen. And no root switch is not that solution because it will be flipped on day 1.

Why would decentralized technology be easy to use?

Limewire was installed on over one-third of computers world wide in 2007 [1]. That's because even grandma could press next->next->next on a window setup file and it just worked. There is no technical reason hosting your email isn't as easy as that.

Look at roof top solar panel. Literally hundreds of millions of households have roof top solar to generate decentralized power. The fundamental complexity in email hosting is hundred times less, but the software engineering community choose to not make it possible.

JS ~~devs~~ writers keep managing to make their bloatware run slow even on highend hardware.

Ryzen 9 7900x + 128GB ram + 6900XT + arch yet Cursor IDE still manages to be incredibly slow and freezing up after re-focusing. Even base VSCodium is many times faster than that. I can have AAA game + kernel build + 100 Firefox tabs active at the same time, yet a piece of JS makes the hardware seem garbage.

Considering the same law is used to strike a 3 hour GPU documentary over a ~30 second clip, I think it serves to corporate pretty well.

GamersNexus' 3 hour documentary about GPU smuggling (which is way more than a vlog as HN commenters like to portray) is struck down by Bloomberg because they didn't want their 30 second clip, which is squarely fair use BTW, of POTUS speaking to be in that. GamersNexus repealed successfully, but Bloomberg tried to bully them [0].

> You go somewhere, you buy, at the end of your meal or whatever they tell you phone only, no card, no cash.

Note that this is likely illegal, even though I'm sure it's very common in certain places, and arguing about legal tender laws is not how you want to spend every meal of course.

But, in principle, in most countries at least, businesses and private citizens are obligated to accept the country's currency to discharge debts. They're free to have an upfront no cash policy, and refuse to do business with you if you try to pay with cash, for example making you leave all your groceries at the checkout counter. But if they claim that you have a debt to them, such as a meal you've already eaten and now must pay for, they must accept any form of the country's currency, such as cash, as a means of you paying that debt off.

Saying this is actually the only same thing to do.

I personally will not care for sub 200 microseconds and think it was a good article if read critically. I think it does describe why you should not do that at the moment if you have lots of nodes that need to sync consistently.

Having a shared 10Mhz reference clock is great and that gives you a pretty good consistent beat. I never managed to sync other physical sensors to that so the technical gotchas are too much for me.

There is madness in time.

Edit: changing some orders of magnitude honestly I feel happy if my systems are at 10ms.

Well I don’t think so.

First, op is talking about Chrome which is not an Apple software. And I can testify that I observed the same behavior with other software which are really not optimized for macOS or even at all. Jetbrains IDEs are fast on M*.

Also, processor manufacturers are contributors of the Linux kernel and have economical interest in having Linux behave as fast as they can on their platforms if they want to sell them to datacenters.

I think it’s something else. Probably unified the memory ?

Cheap and replacable. I found this wasteful. You said "I don’t worry about this too much: they are fully solid state machines, running on low power and low-ish temperatures, thus making their rate of degradation much slower than some beefy machine churning 24/7". How coyld this be measured vs just wishful thinking?
Show HN: I integrated my from-scratch TCP/IP stack into the xv6-riscv OS
by pandax381 | 2025-08-26 06:24:30+00:00
Hi HN,

To truly understand how operating systems and network protocols work, I decided to combine two classic learning tools: the xv6 teaching OS and a from-scratch TCP/IP stack.

I'm excited to share the result: my own from-scratch TCP/IP networking stack running directly inside the xv6-riscv (https://github.com/pandax381/xv6-riscv-net) kernel.

The project uses a modern virtio-net driver, allowing it to run seamlessly in QEMU and communicate with the host machine.

Key features:

- From-Scratch Stack: The core is powered by microps (https://github.com/pandax381/microps), a TCP/IP stack I originally wrote to run in user-space as a personal project to learn the low-level details of networking.

- Kernel Integration: This project ports microps from user-space into the xv6-riscv kernel.

- Socket API: Implements standard system calls (socket, bind, accept, etc.) to enable network application development.

- User-level Tools: Comes with a simple ifconfig command, plus tcpecho and udpecho servers to demonstrate its capabilities.

This has been a fantastic learning experience. My goal was to demystify the magic behind network-aware operating systems by building the components myself.

I'd love to hear your feedback and answer any questions!

In fact, they need you to survive.

You can buy a Linux phone today and make sure the vendors get their food on the table. Software is getting better. If you choose a phone with mainline kernel support (e.g. one that can run Mobian or PureOS), you can literally watch your OS improve month after month.

Alternatively, you can support the user-space ecosystem directly and fund the developers who make it happen. Donate to Sebastian Krzyszkowiak [0] and Guido Günther [1] if you can!

For around 2k it is possible to install a vent hood with the fan outside the building so it is completely silent, and has way more air flow than anything that fits above the range.

Complete silence, performance beyond anything people are used to at home. Most people don't even know the choice exists, and even if you go to a bougie specialty cooking store they'll try to dissuade you from this and instead sell you on a higher priced product that doesn't work as well.

This is not a normative social prescription, but a descriptive natural phenomenon.

If there's a neighbour in your building who is running a bitcoin farm on your residential building, it's going to cause issues for you. If people from your country commit crime in other countries and violate visas, then you are going to face a quota due to them. If you bank at ACME Bank, and then it turns out they were arms traffickers, your funds were pooled and helped launder their money, you are responsible by association .

I’m sorry but no. Maybe it’s my ignorance of TM’s, but O(log n) doesn’t read all input by definition. It doesn’t follow that it is therefore _independent_ of the input size.

What makes a/your TM special that this is the case?

I don’t mean to take too much of your time though, maybe I’m too dumb for this.

Edit: I can sort of see how O(log n) is impossible or at least O(n) in a TM, but to reduce it to O(1) makes no sense to me

> Tariffs increase prices to the benefit of domestic producers and benefits everybody.

Not necessarily, and there are plenty of examples around the world of tariffs that do not do that, but instead cripple the economy. Tariffs are just one aspect. If the domestic supply is not there for one reason or another, you have the worst of both worlds, with high prices and still no re-industrialisation.

You need companies to be reasonable confident that they’ll be making money next year, and you need the situation to be stable enough to let people invest to make it happen. You need those people to be confident enough that they won’t just be crushed by a president’s friend who has more access to power than they have. You need rule of law and due process. Not a kleptocratic oligarchy.

Otherwise you’re just sawing off your leg to repair a broken ankle.

I'm honestly curious why Apple (and other OS vendors like MS and various Linux distributions) still feel the need to tweak their UIs many, many years after having reached maturity.

How many iterations does it take before you get it right?

I get that there's a certain sense of fashion to it, but so often these changes are either neutral or worse, and it just seems so pointless. I don't see any concrete benefits of this year's UI design over what was already there 10-20 years ago.

I'm pretty sure the issue with carbon monoxide poisoning is that you don't actually feel it clearly enough and that it doesn't manifest as "can hardly breathe".

Leaked SoC documentation is a very long distance from having a fully working open ecosystem. Like, dozens of man-years -maybe hundreds. It would be a mistake to assume you can pick any of the sinovoip boards and get that. They use a number of SoC vendors with very different business models, and level of support for FOSS. Certainly there are some who make much less investment in maintaining an open ecosystem than RPI.

>How about automated high/low beam switching

I would want the ability to change that. I actually think I can mess with that on my car.

>enabling the nominal power of your car instead of handicapping it by default?

Big topic for me. My car has a DPF, and appears to have been geared such that despite containing an automatic DPF burn process, the engine never quite reaches the required temperature, so I need to perform manual burns.

I have straight up asked the dealer for a method to enable the auto burn process, manually. And have asked if theres a retune available, to make the gearing just a little bit less efficient, giving me more power and more engine heat.

The issue, pretty much verbatim from their head regional diesel mechanic is that any modifications of that nature would fuck the emissions standards they had to limbo under. So its categorically denied. They also issued me with stern official warnings that anything I do to make the car more reliable may also void my warranty. And the unofficial advice I have received is that the DPF is "f*cked mate" and to "get the petrol hybrid before the government forces it to wear a similar PPF"

The car also very suspiciously moderates the engine output unrelated to gearing/tune. Just sometimes underperforms at random. I believe its computational again, like you say, handicapping it for emissions reasons.

These things are largely optional for me, but I wont mess with them too much until I am out of warranty.

I suspect that the biggest limitation in printing vs. emissive displays is the simple fact that your contrast ratio and color reproduction is severely limited in printing, because the dye is modifying ambient illumination.

This affects brightness and contrast: For emissive displays, you can have emissive values that are several to many orders of magnitude brighter than the 'black point', and more importantly, the primaries are defined by the display, not by ambient illumination.

Part of the magic of HDR displays is manipulating local masking (a human perceptual quirk) to drive bright regions on a display much brighter than the darker regions, so you can achieve even higher contrast ratios than the base technology could achieve (LED back-illuminated LCD panels, for many consumer TVs). Basically, a bright pixel will cause other nearby pixels to be brighter, because you can't see the dark details near a bright region anyway — but other regions could be darker, where you can perceive more detail in the blacks. This is achieved by illuminating sections of the display at significantly higher or lower levels, based on what your eyes/brain can actually perceive. That leads to significantly higher contrast ratios.

(As a heuristic: photographers generally say you can only get ~5 stops of contrast out of a print. (That is, bright areas are 2^5 times brighter than the darkest regions.) Modern HDR displays can do 2^10 or better. YMMV.)

But this also affects color... much of the complexity in getting printers to match derives from the interaction between the imperfect gamut caused by differing primaries, as filtered through human perception (and/or perceptual models). But you can't control the ambient illumination, so you're at the mercy of whatever the spectrum of your illumination is, plus whatever adaptation the viewer has. This feels fundamentally impossible to do "correctly" under all circumstances.

Which is to say, the original sin of color theory is the dimensional collapse from a continuous spectrum to a 3-dimensional, discretized representation. It's a miracle we can see color at all...!

And I welcome the feedback, even if I probably won’t follow it. If everyone thought like you do, then it’d be far nicer to publish the code and maybe charge for support. I’m fairly confident that not enough people feel the same way to make it work.

As to pricing, I need to be able to financially justify the time spent working on the app, and the price is one that I hope will let me do that.

That's missing the point. This is not a value judgement about whether the refugees contribute to society. By being employed they are in fact helping to keep wages lower than they would be if there was a lower supply of labor. The point is that the main benefactors of immigration are corporations, not working-class families. Thus traditionally left-wing labor parties have been against immigration.

We should be using immigration to shorten the workday for everyone, thus counter-acting its effects of wage suppression and giving people more time to dedicate to relationships, thus recovering the birth rate and reducing the need for immigration. Of course this will never happen, because economic growth is more important than people's well being.

I see two overlapping audiences here on HN, the hackers (now called makers) and the VC profit driven crowd. The popping of the bubble is going to hit those two camps differently.

The hackers will be glad to see the price of AI compute and hardware drop like a rock once everyone in the VC world realizes they've overbuilt, and a sell-off happens. We'll be using those resources to build the next things almost immediately. In fact, I'd be surprised if planning for that hadn't already started.

The VC type will ... I have no idea, actually.. I'm not a profit driven person. But experience shows they'll be around to do it all again for the next bubble in a decade or so.

As for AI itself, it will continue to get better and deliver value for those who know how to use it. For me, ChatGPT5 is an amazing improvement for generating code.

Per core, Apple’s Performance cores are no bigger than AMD’s Zen cores. So it’s a myth that they’re only fast and efficient because they are big.

What makes Apple silicon chips big is they bolt on a fast GPU on it. If you include the die of a discrete GPU with an x86 chip, it’d be the same or bigger than M series.

You can look at Intel’s Lunar Lake as an example where it’s physically bigger than an M4 but slower in CPU, GPU, NPU and has way worse efficiency.

Another comparison is AMD Strix Halo. Despite being ~1.5x bigger than the M4 Pro, it has worse efficiency, ST performance, and GPU performance. It does have slightly more MT.

Nice article. It reminds me of another post a little while ago about OCaml. Like OCaml, Scala is getting more systems programming capabilities. Capture checking can, for example, be used to implement safe memory arenas (aka slab allocation or memory pools.) If you can prove that no code has captured anything from the arena, you can prove it is safe to deallocate the arena. This is less fine-grained than Rust's approach, but I think it is much more usable. I think of it as similiar to Zig's approach but with safety guarantees.

The other part, doing away with monads, is also exciting for FP nerds like me, but probably less generally exciting as it doesn't add new capabilities to the language so much as make existing capabilities easier to use (puns intended, of course!)

If you pay attention you’ll see a couple of differences between what the EU does and what the US does. Your example is of a targeted tariff, directed at a specific industry, which is already present in the EU and that was deemed strategic. What it is not is indiscriminate, affecting all countries in the world and all industries with arbitrary rates that change every week.

Targeted tariffs have always existed, and the US and the EEC and then the EU were involved in a lot of trade skirmishes that did result in some barrier being put in place. This is not the same.
