They designed and built a battery that uses up to 70 per cent less lithium than some competing designs.

This is probably a way of phrasing that means it's up to 70% less than the absolute most lithium-requiring designs that few/no one uses, and probably only marginally better than most designs actually used. Since they're very vague about it, I will be sceptical and assume it is way less revolutionary than the headline suggests.

This feels like an advertisement article...single port USB-C PD chargers with 20-30W output in the <$10 range are not at all hard to find already.

Fuck I love the "ok" as deny reason...so simple, so beautiful.

That's not what Tesla is doing though, or the article is about...they (Tesla) are arguing that free speech should allow them to do false advertising of their product.

A high(er) end smartphone has a battery capacity of approx. 0.019kWh (5000mAh), a gtx3080 has a max power draw of 320W so running that (at max load) for two hours is 0.64kWh, which is equivalent to fully charging ~34 smartphones.

According to Phoronix, Ampere's new CPUs have so many cores that Linux doesn't support systems when two of Ampere's 192-core chips (384 total cores) are installed in a single server. For now, the ARM64 Linux kernel only supports systems with 256 cores or less. To fix the issue, Ampere has submitted a patch proposing that the Linux kernel core limit be raised to 512

If you're already at 384 cores in a dual-processor setup, isn't raising the limit to 512 too little? Why not just go for 1024 now that they're at it, especially since the method they proposed doesn't increase kernel image memory footprint.

Hydrogen is incredibly inefficient compared to using electricity directly. You have to first use the electricity to make the hydrogen, this is very inefficient in itself. then you have to "burn" it to drive the vehicle, which wastes most of the energy just like ICE vehicle. So you need several times the initial energy generation to drive a hydrogen vehicle the same distance compared to using electricity directly.

Of course the batteries is then the issue when it comes to EVs, so they're not a magic bullet. But I wouldn't say hydrogen is the obvious better choice either since it is so wasteful with the energy.

IDK, the ability to remote activate climate control, start/stop charging and control charge power to match my solar power are all quite good reasons for me to have my car connected.

We should be able to have nice things without surveillance. We shouldn't refrain from these things, we should legislate so they're not allowed to collect data and share it without explicit consent.

Yet they're still inferior to even older x86 hardware. You can pick up a used NUC (or similar) for less than a pi 4 and it blows it out of the water on performance, while using only marginally more power.

Most races are not against time though... They're against other competitors. The time it takes you is pretty irrelevant, as long as the others are slower.

It's more or less only time trials that are races against time.

You're thinking of ASMR, this is related to ASML...two completely unrelated things.

US cell service plans always seem insanely priced compared to what we're used to here in Europe. They pay a fortune for shitty plans with low data caps, it's ridiculous.

Products do need regular security updates though.

Are these facilities not regularly audited by a 3rd party to maintain their ISO certifications? The stuff mentioned in the article (key card feeler gauge...WTF!?) would/should have been caught in any routine audit.

Pop Socket, never drop your phone again.

Also never fit in your pockets again

Not with my real name, age, gender, address, phone number or even email.

Depending on the type of robot and application, the torque limits may be way higher than what it takes to crush a human being. It's not for shits and giggles that most robots are put in cages/behind barriers. Positions are probably also a lot more static/predefined than you'd expect.

I work with a lot of small robots (they fit on a desk) and they will absolute smash the living shit out of you if they're not set to low enough. Even on lowest torque they can break bones. Obviously they're caged when used in production environments, but all safety can (and often will) be circumvented by staff because it's inconvenient for them.

Reverse engineering an API is not illegal

You're not spending 30+ minutes charging on modern EV's (maybe some cheap crappy ones IDK)...I spent my summer holiday driving around Europe for 3 weeks, and charging stops were always <25min from leaving the highway to back on the highway. The actual charging time was often so short that we barely had time to get the kids to the bathroom and back before the car was ready to drive for another couple of hours. Having them at gas stations in Germany, where there's almost always a decent level of amenities (at least along the highway) is just fine and makes perfect sense.

They're still tracking the crap out of you even if you pay, so they can fuck right off and die in the gutter.

It's an industry that's earning literal billions every single year...they absolutely don't need to have ads, they could serve their paying users a good ad-free product, and still make money. They choose to deliberately annoy their paying customers because they're fucking greedy.

That has absolutely 0% to do with their nationality and 100% to do with with them being general cunts.

As soon as they figure out how to actually mass produce them at an affordable price, and fix the swelling issues during high charging currents, they'll be available.

No its "gig economy", and it's primary purpose seems to be skirting labour laws by calling their employees "independent contractors" so they can save money by screwing the people working for them.

on Spotify there were more ars than songs lately, so they forced me to buy a subscription

Aah, so their tactic is working 100% as intended.

But they didn't force you to do anything. you willingly chose to reward them for their shitty method instead of ditching them because of it.

A used NUC blows a raspi out of the water performance-wise, and they use surprisingly little power when not under load. I run proxmox with a NAS, pihole and homeassistant on a NUC from 2015, and it draws around 9W.

Liftoff hasn't been touched for more than 6 months...it's absolutely abandoned, no need point people in the direction of dead and deprecated apps.

Right over here...just wait on that couch there, Mr. Jensen will be here shortly with your free GPU.

That's absolutely insane...why is it not a requirement to have audits performed by a third party, or the FAA themselves? This is laughably ridiculous, especially for an industry that claims to be focused on safety and quality.

With the significant difference being that a KB still works for it's primary purpose even if not actively developed on anymore. Liftoff is completely broken for a lot of the fediverse, so it's not able to do the only thing a Lemmy app is supposed to do...browse Lemmy instances.

If you insist on keeping broken software on the list, at least make a note that is broken and not currently maintained.

the chargers aren't standard. Each charging site has different plugs

IDK where you're from, but in europe it's all standardized and all cars, regardless of brand, use the same plug for both AC and DC charging. The whole app/rfid tag mess is true though.

The power lines in the cable are disconnected inside the charger by a contactor until communication with the car is confirmed established with a handshake, and then it connects power to the cable. If the communication with the car drops at any point, the contactor disconnects the power to the cable. It requires both effort and knowledge to bypass this design, it basically can't happen accidentally.

Also, the cables you mention are that large, because they're passively cooled, DC car chargers have watercooled cables so they can be much thinner without overheating. And at 4kV you're looking at significantly different insulation thickness as well, compared to the 400-800V that electric cars use.

Doesn't have port forwarding anymore though

The "we can do it by end of this year" he's been toting since 2016 wasn't a giveaway?

The "do not track" is really just you asking them politely not to track you, they are not obligated to stop tracking...more often than not, it is completely ignored and they track you anyway.

Funny thing, most modern refrigerators use DC motors for their compressors so that they can run at variable speeds

No they don't...they use AC motors and a VFD to control the speed.

What if... we just ran them when people weren't in the room?

This is already a thing in many hospitals, and has been used extensively even before covid.

Yes but the overhead we have is nothing compared to the energy needed to make everything hydrogen powered. we would need an absolute absurd amount of overhead to generate all the hydrogen from overhead alone.

It's kind of dumb to intentionally waste 75-80% of the total electric energy initially generated to power hydrogen vehicles.

Using hydrogen to store the occasional grid overhead to be used for the grid later is a great idea, it should absolutely be done ASAP...but it's not a solution to hydrogen powered vehicles.

Surprisingly cheap TBH...

Phew im good then, my car weighs 1 ton so i can just drive with one hand right?
