4 different "buy nitro" "try new animated stickers" "have you bought a new profile background yet?" popups at the same time are also ads.

Fast? Clean? The new app is a stuttery, cluttered mess with more ad popups than a 2010 video streaming site and more framedrops than crysis. Until a few days ago I still used the oooold app and it was much better.

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.

With that, the Germans will have finally won /s

The 5th booster brought my sense of smell back for a month, but it quickly disappeared again :/

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.

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.

It's still 8MB for non-nitro users.
