Honestly, supporting linux makes absolutely no sense for vanguard.

If you use vanguard, it's because you're fine with a company taking full control of your system, installing a rootkit tracking your every move.

If you use Linux, at least part of the reason is because you want to take control over your computer back.

To support vanguard on linux, you'd have had to run vanguard as hypervisor with linux running in a para-VM, or you'd have had to modify most of the linux kernel to add tracking and control capabilities that'd never get merged upstream and would break with every update.

The resulting system would be closer to android or a playstation than to actual linux distros.

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.

No. You can fix the dehydration relatively easily by just giving the person liquid intravenously.

But the primary way rabies kills you is liquifying your brain, which is independent of how hydrated you are.

Why would they need to comply with Apple's ToS to publish apps outside of the app store?

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.

Also note that even a dual boot system is leaky. A kernel level anticheat has enough power to do firmware upgrades on peripherals or the UEFI, so a badly behaving kernel level anticheat could easily take over your entire system in a way that can never be gotten rid of.

The 50€ Patreon tier perks include "everything ad-free". And there's no repo or source available anywhere.

WTF

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.

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've got 14 billion years, a theft takes a minute, then you need 53 recursion levels of binary search to find the moment of the theft. (14 billion years can be split into about 7.3e15 1-minute segments, 53 levels of binary search allow you to search through 9e15 segments)

That means OP assumed that it'd take 1 minute to decide whether at a certain still frame the theft had already occured or not, to compute the new offset to seek to, and the time it'd take to actually seek the tape to that point.

Not an unreasonable assumption, but a very conservative estimate. Assuming the footage is on an HDD and you've got an automated system for binary search, I'd actually assume it'd take 5 seconds for each step, meaning finding a 1min theft on 14 billion years of footage would take 5 minutes.

Badly shielded USB3 causes RF leaks at 2.4GHz. use 5Ghz WiFi or better shielded devices.

Honestly, with high quality USB A plugs you could feel the logo on the side that was "up", and if you knew which side your motherboard or front panel considered "up", it'd be easy to always plug devices in correctly.

Just that the vast majority of manufacturers stopped caring relatively early on, which meant you couldn't rely on it anymore.
