If any cops or cop apologists wanna disagree with this: show me a good cop who arrested an ICE. Because ICE is breaking the law, and as far as I can tell, nobody’s arresting them.

Technology@lemmy.world•China solves 'century-old problem' with new analog chip that is 1,000 times faster than high-end Nvidia GPUsEnglish
41·10 days agoThey used to use analog computers to solve differential equations, back when every transistor was expensive (relays and tubes even more so) and clock rates were measured in kilohertz. There’s no practical purpose for them now.
In cases of number theory, and RSA cryptography, you need even more precision. They combine multiple integers together to get 4096-bit precision.
If you’re asking about the 24-bit ADC, I think that’s usually high-end audio recording.

142·10 days agoThe maximum theoretical precision of an analog computer is limited by the charge of an electron, 10^-19 coulombs. A normal analog computer runs at a few milliamps, for a second max. So a max theoretical precision of 10^16, or 53 bits. This is the same as a double precision (64-bit) float. I believe 80-bit floats are standard in desktop computers.
In practice, just getting a good 24-bit ADC is expensive, and 12-bit or 16-bit ADCs are way more common. Analog computers aren’t solving anything that can’t be done faster by digitally simulating an analog computer.

World News@lemmy.world•Students at British campuses in China ‘made to pledge loyalty to party’, required to take ‘ideology courses’ and participate in ceremonies honouring the Chinese Communist PartyEnglish
85·20 days agoRednote is a proprietary app-only non-federated social network subject to the censorship of a totalitarian government, China. It blocks discussion of 6/4, Free Hong Kong, Uyghur genocide, and probably all the other stuff normally censored in China. I encourage any skeptics to visit the Chinese Wikipedia from within China.

91·20 days agoNo person should have to pledge loyalty to the party to graduate. I don’t think you could sue for this in China. The party controls everything.
It would be a more meaningful discussion if the government wasn’t controlled so much by large corporations and oligarchs.

Selfhosted@lemmy.world•Have you tried self-hosting your own email recently?English
4·2 months agoI have self hosted my email since 2006. I gave up on self hosting outgoing mail in 2021, but I still keep the server up for incoming mail, and still set up throwaway accounts on there.
The hard part of hosting email is getting Google and Microsoft to accept outgoing mail. Tons of businesses that do not have visibly outlook .com or gmail .com addresses are still hosted by those servers.
I had SPF, DKIM, and a static datacenter IP address with no reputation problems. I still couldn’t get through to Microsoft, not even in people’s junk mail directory, until they manually whitelisted my address. Microsoft didn’t allow them to whitelist a whole domain. Google was a little easier, but they added new demands monthly.
In 2025, I can’t get reliable delivery to gmail .com addresses even sending from a hotmail .com address in the outlook .com web interface.

No Stupid Questions@lemmy.world•How does streaming compare to "analog"?
31·2 months agoYeah, true, but that’s mostly fixed costs, and has a pretty low incremental cost for each video delivered. The fixed costs we have to pay regardless.

No Stupid Questions@lemmy.world•How does streaming compare to "analog"?
10·2 months agoElectrical engineer here. There is almost no difference.
The cost of streaming video from a server to your computer is pretty small, basically just transferring the bytes from a hard drive to a network card. This happens in a datacenter on a big server designed to be efficient at it, and serve a ton of people at once. Your own electricity consumption on your viewing device is likely much higher than that. You can calculate your electricity consumption using a Kill-A-Watt or similar device, but here are some averages of measurements I’ve made on my devices:
- PC with 27" LCD monitor: 150W
- 50" TV: 300W
- Laptop with internal 14" screen: 40W
- Phone with 5" screen: 10W roughly, but it’s complicated
- Phone with screen off, speaker only: 2W (guessing here)
- Handheld FM radio: less than 1W
If you look at your computer’s CPU usage while watching video, it’s mostly idle. So most of the power consumption is the screen’s backlight.
Assuming worst-case coal power, releasing 0.4kg of carbon per kWh, and a large TV, and let’s say 10% overhead for the server’s energy cost, that’s 0.13kg of carbon per hour. So don’t worry about it.
Doesn’t it freeze there? It’s in northern Illinois.
Could we put Einstein’s bones in a centrifuge, and run at 200km/h?

Mildly Infuriating@lemmy.world•Leave it to a Bezos-owned company to confuse customers and mislead them for profit.English
15·2 months agoI loaded a bunch of articles until it prompted me to pay. I got the screenshot below. In my opinion, this is an intentionally misleading fake 50c/month offer.

Not sure how much you’re paying for your VPN, but a virtual private server can be had for about $5 per month. You’ll get a real IPv4 address just for you, so you won’t have to use non-standard port numbers. (You can also use the VPS as a self-hosted VPN or proxy.)
$5 per month doesn’t get you much processing power, but it gets you plenty of bandwidth. You could self-host your server on your home computer, and reverse-proxy through your NAT using the VPS.


Yes. But it keeps going forever, and eventually some chaotic-evil person will kill choose to kill 2^43 people, which is a thousand times the world’s population.
