It's in TFA.

These are sometimes called Galactic Algorithms: https://en.wikipedia.org/wiki/Galactic_algorithm

The very first example on the page has a pretty good quote describing their usefulness:

>>> An example of a galactic algorithm is the fastest known way to multiply two numbers, which is based on a 1729-dimensional Fourier transform. It needs O(n log n) bit operations, but as the constants hidden by the big O notation are large, it is never used in practice. However, it also shows why galactic algorithms may still be useful. The authors state: "we are hopeful that with further refinements, the algorithm might become practical for numbers with merely billions or trillions of digits."

The borrow checker exists to force you to learn, rather than to let you skip learning. To make an analogy, I think it would be weird if I complained that I had to "memorize the rules" of the type checker rather than learning how to use types as intended.

Obtaining a custom storage module seems to involving reverse engineering the PCB, printing it and sourcing the NAND modules, and then BGA soldering that all together: https://youtu.be/HDFCurB3-0Q

Not a user-friendly process, I think.

> Cats are also aided by their large and sensitive vibrissae, which are positioned on such locations of their head that the cat can detect nearby obstacles in closer encounters. Vibrissal sensation can compensate for the somewhat weaker vision in cats from closer distances or in poorly illuminated environments. Therefore, it is possible that cats approached the narrow openings in our experiment without differential hesitation, and they could use their vibrissae to assess the suitability of the apertures before penetrating them.

Here's a case study of 42: https://journals.sagepub.com/doi/10.1016/j.jfms.2009.09.018 And there's certainly many more cases than just those at a "referral hospital in Sydney, Australia."

AltStore is a bad joke, you can only install 2 apps (three, minus the altstore app), and you have to connect your phone to a MacOS computer and run the app every week.

Just let me click on an IPA to install it, it's really not that deep!

For dark-net markets, server-side encryption is already seen as a failsafe rather than a feature, and smart users ALWAYS encrypt client side (PGP). That said, for activities like these, smart users are not necessarily the majority...

Could you link the change? At least a few days ago virt-manager still seemed to have scaling issues with guest displays, on nixos-unstable. I had viewer scaling on though as a workaround, so maybe I just didn’t notice.

Prohibition increased alcohol-related deaths and created a black-market of products so much worse than the regulated market before or after[0]. I would say that, in fact, prohibition did not work.

And neither does current drug prohibition. Fentanyl deaths are directly caused by the black-market supply of drugs in the US, and it isn't "decriminalized" cities like Portland that are leading these charts[1]. The current drug prohibition just means that the demand that will always exist is being supplied by mis-dosed poison instead of a well-regulated market like modern alcohol (and marijuana in some states).
