No country is running a "population must increase forever". You only hear that when the public pensions are discussed because they are unsustainable. The argument is not " population must increase", it's more "human labor is the most critical resource and we must get as much as we can".
You can fear the results of runaway immigration in the short term, like cultural clashes, organized crime and brown people in your neighborhood. But you can't deny the results on the long term when you allow talent to go to your country and end up with more nobel laureates of New Zealand origin than New Zealand.
First step towards a purge civilization. Also, rather narrowminded (to be expected, tho) to not expect your population to naturally grow beyond 10m (at 9.1 now) just based on the normal progress of healthcare and wellbeing.
I hope early home robotics will be like a game console launch - a community rush to break through any initial barriers to homebrew. Specific early firmwares will be desirable and a whole community will form around creating exploits and running user software. As old robot units fall out of service and are sold in bulk, the community will pick them up and keep them running.
I for one eagerly look forward to alien-autopsy like videos of people reverse engineering robots that they acquired by 'disabling' whatever equivalent of Lime/Bird/Volt service sends out on the streets to do stuff for people.
It'll be neat to walk through some weirdo mechanics shop that's full of robots in different states of disassembly that have been repurposed to help with whatever mad scientist hacker schemes that they have in mind.
It does, but as you really can't get money out of it in a reliable way by exploiting the user addictive behaviors, it doesn't have that effect on society.
It's just a cool place to visit now an then an check cool stuff out.
Kind of interesting how many people don’t realize that the purpose of Hacker News was to be an advertisement for Y Combinator and their portfolio companies.
You don’t see it as much these days, but YC portfolio companies can post privileged threads on this site for job listings, which in practice double as ads for the company. You’re not allowed to comment on them.
I haven’t seen one for a while because I suspect every company is already inundated with 1000 applications for every job in this market, but this is what Hacker News was for.
Y Combinator is right there in the URL. People know and don't care because it's a well run forum with interesting discussions, the privileged posts don't change that.
I think most people know this and are fine with it. YC owns the site and advertises their stuff on it sometimes. The site itself is not trying to milk you for every penny or trying to exploit you.
I'm gonna have to "yes, but" here. Yes, there's no doubt the limitations of a media are interpreted by most as desirable things to chase, like scanlines in a crt that's outputting a low resolution image.
But there are also certain qualities in analog audio or video that were lost or severely degraded in the technologies that came after. For example, you need an extremely high bitrate mp3 to get to the fidelity of a vinyl (CDs can achieve it without issues, though) and in crts image clarity in movement is still unmatched in modern displays, and will probably always be due to the sample and hold nature of modern displays.
I think people in cinema have (and want) more control over the take. For a photographer, autofocus is quality of life, for a cinematographer it can get in the way very fast in everything that's not following subjects.
Yeah, fuses are more of a overload protection kind of stuff. For cases where the load is trying to kill itself and you with it you need current limitation circuits, either on a converter or a latch current limiter.
Orrr you can design your circuit to survive a short condition for a bit longer than a fuse takes to blow. For old cars this was common, let whatever is short take all the current it wants for a tenth of a second and forget about it.the battery may lose a bit of useful life but those things were gonna fail early either way.
Just want to mention how much I appreciate this discussion and the opportunity to learn from it. This is what I come to HN for (nowadays there are also really interesting YouTubers who do informative teardowns of power electronics and other devices, too e.g. Labo de Michel, Watch Wes Work, etc.)
The average Joe? My wife has used Linux since the mid-2000's. Her career was in Sales, far removed from anything technical. She loves Linux compared to Windows, her new laptop came with Windows and she bugged my for months to upgrade it to Linux, which I did recently. She doesn't use the terminal at all. Kubuntu, btw.
Funnily enough the terminal which was the reason people said linux is too much of a hassle is the very thing that now makes it so you can easily fix your computer with natural language.
Sure the problem is it will still come with problems out of the box but that's mostly on laptop manufacturers. At least now you can easily fix them with an agent.
For me it's much more fun to tell my computer what I want and to get it than to scroll through a settings GUI but to each his own
That's what KDE (and gnome, to a lesser extent) have been trying to do for a long while.
The fundamental issue is that a GUI is a static abstraction over a CLI that allows for millions of potential combinations. You can only expose so many options in a menu before the interface becomes completely unusable.
To expand on your analogy, it’s like running a restaurant that only uses automated vending machines to serve food. It works perfectly fine if someone just wants toasted bread. But the moment a customer asks for more than toasted bread, you're toasted.
Imho, the best bet for the future is a bunch of pre loaded llm skills and clis an agent can work with: getting the chef to use pre-approved hardware, sorta, that can cook up anything that is needed.

But is that an issue? Macs have had this solved for almost half a century: You expose things in the GUI that normal people need, not everything. For hackers, they can still go to the command line to hack.

Good point. I'd say, Linux has inherent complexity across multiple dimensions (less hardware integration, multiple stacks (is it running systemd-networkd ? Or maybe dns
macOS also exposes more advanced things through the GUI but not by default. Its largely undiscoverable, but holding option before clicking something generally offers more options (e.g., hold option and click wifi in the menu bar to get all the detailed connection information).
I like that method, keeps the default GUI clean but still offers GUI options for most things if you know where to look.
I agree but its becoming increasingly clear that "chatbot-as-the-CLI" is likely a "worse is better" situation. It's clearly crappier and slower than just hitting a button, but everyone knows what they want and they know how to put it into text. CLIs in the past never could cope because they relied on exacting, esoteric syntax, so mere mortals had to learn a lot about how to translate what they want "Send a copy of this photo to my friend Sally". So a button is abstracted that says "Send" and "Attach" and some file-based metaphor is built up to allow the work to map better to what people know and understand and can intuit.
My mom can't find the button in the GUI though, and odds are it would be buried in menus she'd get lost in. She can type "Send Sally this picture" into a box and hit go. Anyone literate can.
One thing that's been really useful for many years is the Help menu in MacOS. You click it and start typing the command you are looking for, and MacOS conveniently opens the menu and any submenus and shows you the command with a big blue arrow. Wouldn't this be easy to pair with a simple AI, so that people can more freely type what they want to do? Maybe even make it Spotlight accessible.
I like the visual and thus get along much better with drag-and-drop than any text based interface. So for me (and maybe your mom) the best solution would be that Sally was a window you could open and drag things to. Surprised that Apple and nobody else ever did this on desktop. At least on iOS, your friends are pictures that appear whenever you press share, but it's not perfect.
The closed loop experiences a phase margin loss that is exponential with the frequency. At lower frecuencies it is negligible, but if you get close to the frequency of the delay the phase margin reduction becomes dramatic and the control goes from stable to unstable very fast.
If the sensor has a limited bandwidth, you add the conversion delay and then the computation delay on top of that you end up with a max workable loop bandwidth in the low tens of kHz and anything higher will have overshoots, oscillations, etc.
You see this in low cost products like MKS SERVO42x, where they're doing FoC with a GD32 MCU. It works; the motor runs cool, smooth and quiet, but the system is limited to 3000 RPM, and struggles with rapid acceleration because the control loop is too slow.
I have tried one. It has no torque. For what looks like an awesome product, it does not have the power to drive a peristaltic pump. I used the same motor on a TMC stepper controller and it's completely silent and works. It's open loop, so comparing apples to oranges but I am not sure what the MKS servo driver on a motor could actually do, aside from spin unloaded.
These can deliver 2.5-3A/phase, which should ample for a pump. Respectfully, I wonder what motor was involved and whether the current was configured: they come out of the box with conservative configuration so people don't burn up motors.
This is exactly correct. Low 10s of kHz is quite functional for machines moving in human space / speed.
If one is trying to do some assembly line (max # of operations per second), the power requirements alone get hard to manage. And then you're managing back EMF, eddy currents, heck, air resistance!
My rule: have dedicated low-level hw provide smooth PID response, mostly on the P term; and have a higher-level control produce the setpoint. Faster response means less need to rely on I or D terms as much (just because delta-T is so relatively small).
You can fear the results of runaway immigration in the short term, like cultural clashes, organized crime and brown people in your neighborhood. But you can't deny the results on the long term when you allow talent to go to your country and end up with more nobel laureates of New Zealand origin than New Zealand.
