The connection itself wouldn't get slower, but the outer mechanism using that connection may retry, and the retry may be successful. The appearance to the user is one of slowness.

For example, one of the symptoms of networking packet is slowness. Assume 2% of packets are lost. A packet is lost, the receiver re-requests it, and the retry has a 98% chance of being successful. End result: the transmission completes, but at a slower pace.
that language is unpredictable and using LLMs in control systems is a delusional marketing

> Third RANT please STOP making cherry, OSA etc profiles. Very old IBM keyboards have solved the height issue with a simple parabolic support, there is NO DAMN REASON to make flat support and different height keycaps making limited room to move them on the keyboard.

Some of us like to experiment with various profiles (my favorites are MT3 and Cherry and I rotate them every couple months on my keyboards). You can try XDA and DSA profiles, they're qute flat.
Server components, which are in Next.js (using React's canary branch). Server components are not yet in official (i.e. non-canary) React, and the React team supports this move (as do I).

> It will be interesting to see how that shakes out, going to ARM would complicate backwards compatibility so they would need a very good reason to move.

Sticking with AMD for GPUs makes sense no matter the CPU architecture. AMD is competitive on x86, and at the moment Samsung is working out the kinks to integrate Radeon GPUs with their ARM CPUs... so once Samsung has proven the concept works (and, of course, paid for the effort), maybe large consoles will make the switch.

It shouldn't be much of a problem for game studios in the end, most games run on one of the household-name engines anyway and they have supported ARM for many years for mobile games.
Again, that has a whole bunch of practicality plot-holes, as if you're throwing interesting scenes against the wall to see what sticks like zero-G spaghetti.

Everything you've described could be accomplished better closer to home, such as with a sun-synchronous orbit [0] or at most of the local Lagrange points.

Insanely better on solar light supply, emergency resilience, incoming essential goods and staff, and most importantly your gigantobanana might still be edible by the time it reaches anybody else. (Without spending ridiculous amounts on fuel or transit times of over a year.)
Makes me think back to this great blog post from last year: Software Bugs That Cause Real-World Harm (https://pointersgonewild.com/2023/05/29/software-bugs-that-c...)
In the video I linked, he was unable to induce any noise into the speaker wires greater than -130db at 60hz. The threshold for human hearing in absolutely ideal circumstances is about -115db. Anything less than that is provably inaudible for all frequencies, and for 60hz the threshold is much higher than -115db. The noise floor of the room only raises that further. For perspective, the very best state of the art DACs can only keep noise levels to -123db and just a few years ago the number was significantly worse.
They did, but to get it running as well as they did they had to deviate from generic ARM by adding support for the x86 memory model in hardware. Apple was in a position to do that since they design their own ARM cores anyway, but the off-the-shelf ARM reference designs that most other players are relying on don't have that capability.

I feel so much of speed is perception. When I first got the internet I have no problem waiting 3-5 mins for webpages to load. Now I expect 3-5ms. The current context of your experience of speed might influence your expectations when using older equipment.
Batteryless devices are superior to whatever we had in the 90s. Blue screen of death was a daily occurrence in the past. I don't remember having any device issues in the last 10 years. Devices with batteries are having issues with voltage drops.
my laptop can receive packets as quiet as -90 dBm

For comparison, GPS signals in good conditions are around -125dBm, and many receivers can go down to -165dBm, so WiFi signals are still much stronger in comparison.

How much smaller? The main theme in the article should be its comparison against conventional text compression. It seems like an important information.
A million bucks could have got him and his family many great trips to see the best musicians in the world play in beautiful places with amazing acoustics. In that scenario, when he died he would not have had the "best stereo in the world", but he would have been surrounded by people who loved him and all of them would have had memories of those experiences that would last far longer than the short period of time it took them to part out his "masterpiece".
Some manufacturers, such as Apple, have been intentionally making devices slower to drive sales of new products. Potentially Microsoft does the same with Windows. For instance, they recently announced that computers lacking a certain hardware component will not be able to run new versions of the OS, making hundreds of millions of perfectly running computers obsolete.
Ask HN: Why did Bill Gates stop tweeting?
I recall when Pandaria hit there was some resource where you could get only like one a day but they could be sold. The power gamers and the server first people were buying all they could to craft gear to ratchet up the Raid ladder ASAP. I convinced a couple of my friends to sell all theirs at the prevailing price, which was just stupid high, and on about the day we would have been able to craft our first item, the price had crashed so much we bought them back at a lower price. If you waited a few more days, you could buy enough for two items.

Getting 70% of the way to a goal has 0 value. You can often sell your patience to other people in that game.
most people aren't sophisticated enough to identify those issues practically speaking sadly

e.g., I'm one of the only people on my team at work whose computer just works consistently since I understand these things and sidestep well intentioned but poorly conceived it policies such as untested updates that nearly brick laptops often...
North of 55 has ice, but isn't all ice sheets. The most extreme example is probably the warm water port of Murmansk at 68° 58'.
Class-D amplifiers pump out a signal literally buried in noise. You can't hear it because it's all shifted beyond human hearing and filtered by the speakers.
Huh? You want to shut the company down or nationalize it, and I want to give it entirely to the plaintiffs, but you don't think my idea is fair? I'm not sure I see much difference between our remedies.
I'd start with getting some sort of working governance structure going. The sheer number of duplicate libraries all competing with each other has to be hurting Nix. Trying to figure out a TS/NodeJS build was an utter nightmare a year ago as I ended up going through five different projects, including the new "internal" solution, none of which worked reliably.

I contributed to the community for about a year and have since left for a number of reasons, but this is near the top.
Good article, but there's one thing that really bothers me:

> perhaps because of his serious and scientific background – he has a physics degree from Harvard and studied aerospace engineering at Stanford [...]

Which, for the thing he's doing now, is not a serious background! Knowledge isn't transferrable and there are plenty examples of people who transfer fields with unwarranted confidence and make totally bogus claims (see the Nobel disease [1]). I wish we would stop claiming the opposite, because especially in a field like nutritional sciences you can find some "evidence" for any theory (see eg. the Chemical Hunger drama [2]).

React is fundamentally bad technology. I know there are historical reasons for the virtual dom but the reasons that justified it don't exist anymore. If you want to do anything interesting with react that involves interacting directly with browser APIs you need to deal with these absurd use effect hoops to initiate state with references to dom nodes.

I've worked on 4 large react code bases and they always devolve into these blobs of non-deterministic async state with unpredictable performance.

I actually like JSX and the component model so I just use solid-js which is everything I like about react but with effortless performance and you can actually get away with never using effects so your code can actually be deterministic.

I definitely had a desktop replacement laptop which got terribly clogged with dust in my dusty old house and revived it with a spray can of some F-gas that has terrible global warming potential. I was hoping we'd get a fluoroketone based replacement but now we know fluoroketones are dangerous PFAS (makes me wonder what to do with the expensive 3M contact cleaner I bought now that I think of it)

I had two mac minis that operated in the same conditions and seemed well designed enough that dust got separated from the air that went through the computer so it never got clogged up.

My father is pretty much like Fritz but without the audio obsession. He's now in his 60's and his whole life he only cared about making money an being busy all the time with work.

Everytime I ask my father how he is he will always reply how well his business is going. I wasn't surprised by the following quote from the article because it's exactly how people like him are:

One could argue that the information page you're profiling is designed for maximum attention grabbing, and is for an OS that is based on containers, development, and a combination of the two. If you're primarily a kuberbetes dev interested in working and reproducing locally, you probably have the resources on your machine to render this smoothly and properly. And have a fast enough connection to make the bandwidth claims negligible.
In that way, I guess it's good gatekeeping for who and what should run Bluefin. I recently learned this myself after installing Bluefin DX on both a low resource machine and my main dev box.
Protip: probably should be used only on your main dev box at the moment

100%. RAM is always the culprit IMHO, every release has a few more features that need a persistent daemon.
Systems are built to be fault tolerant because hardware errors are inevitable. Bit-flips in RAM and disks, line noise in transmission circuits, voltage fluctuations, etc. And these problems are statistical. In a new machine the chance of error may be 1%, then as it ages the error rate increases to 10%. Repeat something a billion times and those percentages mean you have a million errors. Not only in time but density; a chip with a thousand transistors is going to have fewer problems than one with 10 million. That's why a much older system can be faster than an old but more recent one. But also because the older system will be less fault tolerant. Back then the cost of handling a bit-flip or low-voltage wasn't higher so they ignored the errors and continued to run at full speed as it corrupted your data.
Sad to see but my overlapping hobby (miniature wargaming) has some cross over and model train stuff is so expensive even compared to miniature wargaming which isn’t very cheap itself.

Yes, there are a handful of policy areas where the politics really do matter -- if you need it, did the state sign up for Medicaid expansion? If abortion may sadly be necessary, is it legal there? -- but I think in most areas, day to day life is no more oppressive in those states, and frequently the demographics are no less diverse (they are often more so).

We need to keep in mind the magnitude of coercion, or even of oppression, that arises simply from economic forces -- and these generally squeeze harder in the blue states. If the states with the "good politics" can't supply housing at a reasonable price, and if their affordable universities won't let your kids in, then what good are they? A red state with "bad politics" may be sufficiently cheap that the freedom it offers from wage-slavery may outweigh whatever oppressive laws are on the books there. The same goes for other countries. Suppose a country nominally has an authoritarian ruler, but he leaves ordinary apolitical people alone, and prices for medical care are reasonable. Maybe that's still a perfectly nice place to live? Maybe it's better than struggling to pay rent in the "good place"?

As for Texas and Georgia, local politics also matter. Some of the cities are blue islands. So you can't judge a county based only on what state it's in.

But if people are so blinkered that it's literally worth their entire life's wages just to own a house in the "good place", then I guess that's their problem.

That's my issue. The sheer amounts of money we're talking about are staggering. And you have to survive within an abusive corporate structure to get the money. Why tolerate that?

How can you have an emancipatory politics on the one hand, and sign up for lifelong debt on the other? It is good to try to free others, but if you can, shouldn't you try to free yourself first? Then, how can you free yourself in one of the places where money-power is strongest?

High speed digital signaling over differential pairs requires precise impedance control to handle multi-gigahertz data rates. You're paying for that in a high quality USB3 cable. Audio signals running below 20 kHz are in a completely different electrical regime that doesn't require special manufacturing attention. It's easily doable with 19th century technology.
phthalates (in almost all plastics)

Polyethyelene, the most widely produced plastic, does not contain phthalates nor need other plasticisers.

the amount of people in denial or just now realizing plastic is toxic to humans and animals is mind-boggling.

"That's just your opinion," as the saying goes. Truth goes out the window whenever there's an ideological battle of control fueled by ignorant "environmentalists" producing numerous p-hacked crap studies and spreading "plastics = bad" propaganda. Not all plastics are the same, and the mostly widely used ones are certainly not "toxic".

We're certainly in a post-truth world. I wouldn't believe this "news" especially if it's from the MSM.
I run NixOS on a VPS at work. It currently hosts a noVNC dashboard for monitoring. I didn’t nixify the app yet.

I allocated a Debian and ran nixos-infect on it and started from scratch, even though I have done this for two other machines, because I’m still experimenting with the basic setup.

I do commit changes to git and fork it on company git. But I don’t redeploy remotely: https://discourse.nixos.org/t/deploy-nixos-configurations-on...

I’ll need to make noVNC a part of the deployment (not just its dependencies, like python3).

I should deploy using AWS AMIs, and make a config for the dashboard.

But the NixOS on Hetzner docs are not nearly as easy to guess the best path through. Can you recommend a way to boot NixOS on a Hetzner VPS that is better than nixos-infect?

Maybe, it's just me - I miss the good old days when sites didn't have anything to do with react or similar. Everything was just plain old hyperlinks and some basic JS. I am not even talking about the 90s, just look at what Facebook used to be in its early days - such a simple UI, just based off of hyperlinks, very basic JS. That simplicity alone made it such a joy to use.

Today, I don't even feel like logging into Facebook, because a fucking dropdown menu for a post (which barely has 4-5 options) is a Component that is loaded via AJAX. This is not even an overstatement.
