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.
The affordable Sony Xperia 10 series is really good. My new Xperia runs circles around my OG Pixel, costs basically nothing, is waterproof, has upgradable storage and a headphone jack, and besides Apple, Google and Intel, Sony is the only manufacturer that actually has working bluetooth.
It’s not just office, SH and many other parts of the German government have been slowly replacing the entire O365 suite with OpenDesk, which is an open source product based on Matrix, Jitsi, LibreOffice, and a few other tools.
The goal is to have a fully integrated solution for calender, chat, calls, documents, cloud storage, etc.
My employer is developing parts of that solution and we recently switched our internal communication over to it, and tbh, it’s working really well.
Now is the perfect point in time to do it, with the GDPR ruling regarding O365 and Microsoft fumbling the migration between old teams and new teams.
In timekeeping, there are so called stratums to describe how correct a clock is.
Stratum 0 is a physical process, an inherent property of the universe. An atomic clock would be stratum 0.
Stratum 1 is a clock defined based on a stratum 0 clock. For example, GPS clocks are usually stratum 1, so are timeservers at universities with atomic clocks.
Stratum 2 is a clock defined based on a stratum 1 clock, for example, your router’s ntp server if it syncs its time based on gps or a university’s timeserver.
So if we adopt this jargon for units:
Meter is a stratum 1 unit, defined based on the stratum 0 properties of lightspeed and cesium resonance.
Inch is a stratum 2 unit, defined based on the stratum 1 meter.
You need to be able to have multiple nodes in one LAN access ports on each others’ containers without exposing those to the world and without using additional firewalls in front of the nodes.
That’s why kubernetes ended up removing docker support and instead recommends podman or using containerd natively.
There’s no alternative for 0.0.0.0 and a firewall if you’re e.g. using kubernetes.
That assumes you’re on some VPS with a hardware firewall in front.
Often enough you’re on a dedicated server that’s directly exposed to the internet, with those iptables rules being the only thing standing between your services and the internet.
The EU demands that alternative app stores or individual users can do exactly that.
Apple disagrees.
That’s precisely why this is back in court.
It being totally without rules or terms is exactly what the EU demanded.
Why would they need to comply with Apple’s ToS to publish apps outside of the app store?
Even half an hour next to the PA without special ear plugs is enough to permanently harm your hearing.
Seriously, stop being an asshole. Coil whine is a well-documented behaviour that creates a loud, high pitched noise.
As coil whine is at the very limit of what human hearing can accomplish, it doesn’t take much until you’re unable to hear it. So you’re likely too old or went to too many concerts to be able to hear it.
Good ears? the question is when, not where, and the answer is half a lifetime ago.
It’s just like those shitty recipe sites that tell you their grandma’s life story for hours before giving the recipe. Get to the point, who cares about the anecdotes of some writer?
I don’t want to connect with everyone always everywhere. It’s just like small talk, which may be acceptable or even essential in some cultures, while considering rude and wasteful where I’m from.
Considering that reading source code can take a long time
You’ll get faster over time, until reading code is faster than reading documentation, as code will always represent what’s truly happening, while docs are frequently outdated.
In a language the user isn’t familiar with
If you’re not that familiar with the language, it’s likely you won’t be contributing to the project. Open source projects usually to have quite limited resources, so they tend to optimize docs and dev UX for people who are likely to contribute.
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.
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).
