That’s a common misconception. It’s the Amps that cause fires, not the voltage.
The 5090 uses 600W, at 12V that’s 50A, but at 120V that’d only be 5A and at 240V only 2.5A.
50A melts cables and burns your PC down, 2.5A won’t. The only risk of higher voltages is that they can jump across small air gaps much easier.
when you do need power you need a special circuit.
We also have a standard socket and a high power socket.
Expect our normal outlets provide 230V 16A 3.5kW (3kW sustained) and the typical high power outlets outlets provide 400V 30A 11kW or 400V 60A 21kW.
Which is why typical electric stoves here use 11kW and typical instant water heaters use 21kW.
Though probably the most noticeable advantage is in electric car charging.
Just go ahead with the tutorial. Kotlin is basically identical to Java with only tiny changes, and you can just look those up whenever you see something new.
The UK spent decades convincing everyone that all bad decisions are made by the EU and all good decisions are made by Westminster. That’s the first mistake.
If the UK had properly educated its citizens about what the EU actually was and did, no remain campaign would’ve been necessary whatsoever. But it was politically convenient to have a scapegoat.
And let’s be honest, remain aka “remoaners” had a ton of arguments all the time. But brexiteers just wanted to enter the magical land where the UK still mattered and they’d eat their cake and have it still.
NIF can’t really ever reach Q>1. All the statements of having reached that only include the energy that reaches the capsule. The energy the lasers actually use is orders of magnitude larger.
This theoretical Q>1, where the plasma emits more radiation than it receives, have been reached by other reactors before.
But while tokamak or stellerator designs need a 2-3× improvement to produce more energy than the entire system needs, the NIF would need a 100-1000× improvement to reach that point, which is wholly unrealistic with our current understanding of physics.
Most fusion attempts try to keep a continuous reaction ongoing.
Tokamak reactors, like JET or ITER do this through a changing magnetic field, which would allow a reaction to keep going for minutes, the goal is somewhere around 10-30min.
Stellerator reactors try to do the same through a closed loop, basically a Möbius band of plasma encircled by magnets. The stellerator topology of Wendelstein 7-X was used as VFX for the closed time loop in Endgame. This complex topology allows the reaction to continue forever. Wendelstein 7-X has managed to keep its reaction for half an hour already.
The NIF is different. It doesn’t try to create a long, ongoing, controlled reaction. It tries to create a nuclear chain reaction for a tiny fraction of a millisecond. Basically a fusion bomb the size of a grain of rice.
The “promise” is that if one were to just repeat this explosion again and again and again, you’d also have something that would almost continually produce energy.
But so far, the NIF has primarily focused on getting as much data as possible about how the first millisecond of a fusion reaction proceeds. The different ways to trigger it, and how it affects the reaction.
The US hasn’t done large scale nuclear testing in decades. Almost everything is now happening in simulations. But the first few milliseconds of the ignition are still impossible to accurately model in a computer. To build a more reliable and stronger bomb, one would need to test the initial part of a fusion reaction in the real world repeatedly.
And that’s where the NIF comes in.
If you actually calculate the maximum speed at which information can travel before causing paradoxes, in some situations it could safely exceed c.
For two observers who are not in motion relative to each other, information could be transmitted instantly, regardless of the distance, without causing a paradox.
The faster the observers are traveling relatively to each other, the slower information would have to travel to avoid causing paradoxes.
More interestingly, this maximum paradox-free speed correlates with the time and space dilation caused by the observers’ motion.
From your own reference frame, another person is moving at a speed of v*c. The maximum speed at which you could send a message to that observer, without causing a paradox, looks something like c/sqrt(v) (very simplified).
Cloudflare actually had to disable them because someone managed to automate them with AI too.
Interesting, from what I can find online even though it’s unique to the vita it’s still just the memorystick pro duo protocol under the hood, with a DRM system similar to the one Sony uses for their modern CFExpress Type A cards.
Hey, have you ever met Taylor Swift? I heard she gives great IT security advice over at https://infosec.exchange/@SwiftOnSecurity
It’s still 8MB for non-nitro users.
I still run the last pre-JS version of the discord app on my phone, and it’s sooo much snappier.
Was that the memorystick pro duo, which actually beat even many early UHS-I SD cards at write and read speeds?
Element has the same costs as Signal. So far, Element has been lucky in being able to raise money by selling support contracts to governments or companies using Matrix, but even that isn’t enough, which is why Element has been raising money for the Matrix Foundation for almost a year now (with little success).
Are we sure it’s Sony and not just Zaslav again?
Microsoft actually locked down the BIOS on several Windows 10 S devices to prevent users from installing non-MS OSes with enforced MS-only secure boot.
That just sounds like you need more enforcement against fake subcontracting.
Better idea: family-owned companies, upon death of the owner, get turned into a coop owned by all the employees of the company, each getting 1 share.
The recent technology connections video cited a lot of statistics on this topic, and at least household fires are primarily caused by overcurrent, not by arcing.
You probably know more than me — I only studied compsci with ee as minor — but from my personal experience, I’ve seen many cases where overcurrent caused damage, burns or fire, but I can’t remember a single case where arcing caused actual damage.
Even in cheap chinesium powerstrips, the primary cause of fires is overcurrent due to AWG 22 copper clad iron wire, not arcing. (Though the switches usually weld themselves together after a few dozen uses).
