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

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.

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.

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

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.

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.

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.

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.

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.

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.

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 ICE's max speed depends on model and variies from 250km/h to 300km/h. These speeds can be reached on:

  • Hannover-Würzburg (280km/h)
  • Mannheim-Stuttgart (280km/h)
  • Oebisfelde-Berlin (250km/h)
  • Siegburg-Frankfurt (300km/h)
  • Köln-Düren (250km/h)
  • Rastatt-Offenburg & Schliengen-Haltingen (250km/h)
  • Nürnberg-Ingolstadt (300km/h)
  • Ebensfeld-Leipzig/Halle (300km/h)
  • Wendlingen-Ulm (250km/h)

There are more of these tracks currently under construction:

  • Stuttgart-Wendlingen (250km/h)
  • Bashaide-Rastatt (250km/h)

And many more are currently in the planning stage:

  • Hamm-Bielefeld (300km/h)
  • Oebisfelde-Berlin (300km/h)
  • Ulm-Augsburg (300km/h)
  • Gelnhausen-Fulda (250km/h)
  • Frankfurt-Mannhein (300km/h)
  • Bielefeld-Hannover (300km/h)
  • Nürnberg-Würzburg (300km/h)

If you can only have a good experience by installing malware, you don't have a good experience.

I really should finish building that nvidia jetson based hardware anticheat that'd allow anyone to cheat even in vanguard protected games with perfect accuracy for just ~150$. Ring 0 anticheat's only use is to spy on you and yet people will continue defending it until someone's proven just how useless it is.

What you're describing used to be right under X11, but under Wayland the compositor handles all rendering itself. For Gnome that's mutter, which is also maintained by the gnome project.

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.

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.
