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).

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.

This is also the same for radar hacks. Or if you play a MoBa, screen alert hacks. All they do is boost player performance without being detectable. Most server side anti-cheat can only pick up on certain things, I don’t know Minecraft’s solution but I doubt it catches disguised cheating via code injection.

The real question is: why does the client even know about players who aren't visible to them?

The solution with Minecraft PvP is simple: if you can't see a player, the server won't even tell you the player exists.

If you use a wallhack you can see players walk behind a wall and then just disappear as if they had logged out, and suddenly reappear from behind the wall on the other side as if they had logged in.

What Minecraft anticheat systems do is relatively simple:

  1. They only send information to clients if the players should have that information as well
  2. after every movement, action, etc they calculate whether the movement you did would have been possible by a real human given the information you should have had at that point, and if not, you're banned
  3. all actions and movements are compared over minutes of gameplay and, if your actions are too different from all other players, sent to review by a human (and potentially banned)

You don't need to install anticheat on the player's computers. The players can run all the mods and cheats they want, but cheaters can only see the same information as all other players, can only move the same way as all other players, and can't shoot faster or more precise than any other player.

So while some people may still be cheating, at that point you can't tell the difference anymore.

For comparison, this is btw how all other software outside of gaming is written. In all other parts of computer science you'd get fired if you did what game developers do.

Imagine if reddit would send all DMs to all users and only make the DMs invisible on the client. That'd be an immediate lawsuit. Instead, the server validates who should be able to see what and only sends that information.

Or imagine if banks allowed anyone to make any transaction they wanted, only the banking app verifying that you've actually got that much money. Utterly ridiculous. Of course the servers validate whether you should actually be allowed to do that.

As result, writing third party apps for most websites is allowed, the EU even requires banks to support third party apps, but modded clients for videogames are considered a security risk. What the fuck.

Why'd you have to use TC? KDEs dolphin can do all that natively.

Personally, configuring KDE was much simpler and more robust compared to the dozen addons I needed for Gnome, which also broke every now and then after updates.

[-] justJanne@startrek.website 2 points 1 year ago

I tried that, but IMO it's much simpler and more robust to just configure KDE than to install a dozen Gnome extensions that end up broken after updates anyway.

You're conflating two different things. Law is political, and that's fine. Court rulings are not supposed to be political, though, they're supposed to be based solely on the rule of law. That's the only way to ensure the law applies equally to everyone, rich or poor alike.

I agree that voting/non-voting shares are bullshit, but so are shares held by anyone but the workers themselves (which would be a co-op).

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).

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).

How is someone using the road to get to work, school or the grocery store automatically an asshole just because they use a bicycle instead of an SUV or a horse-drawn carriage? Don't they have the same right to use a lane of the road as you do?

(Not talking about lycra-wearing racing-bike cyclists using the road as gym here)

If you actually think about it, it's absolutely makes sense. The Autobahn has additional stopping lanes for broken down cars and several meters of grass to each side, which means you can safely drive hundreds of kilometers an hour while still being able to see obstructions early enough to brake in time.

Slower motorways have smaller setbacks, but still enough to keep their speeds.

City streets where you can't see people entering the road in time to brake usually have relatively low speed limits to reduce the braking distance as well as the damage caused by a collision.

But if the visibility or braking distance are affected due to weather or broken streetlamps, it's up to you to slow down accordingly. But even for situations like that traffic planners usually add additional signs, it's common to see roads with signs that say

/❄️\
(60)

to warn people to drive slower when the road is freezing or signs that say

/🦌\
(50)
[400m]

to warn of crossing animals in the next 400m and set a lower speed limit.

The same obviously applies when it's not crossing deer but crossing pedestrians.

I still hope it's just a driver or configuration issue, for now I just dual boot for resolve, but that's obviously not a long term solution.

Sadly even Resolve Studio doesn't support h264 all-intra as used in Sony's XAVC-I and XAVC-S-I on Linux, which sucks.

With XAVC-I CineEI Slog footage the metadata is enough that Resolve treats it as Raw (in fact, it's more flexible than braw). So losing this functionality really hurts.
