I don't know about y'all, but this paradox was resolved to my complete satisfaction in a blog post some years ago, I believe by Scott Aaronson, though I can't find the link. If the predictor has such a good success rate, then it must be simulating people's brains, but since it's not always right, the simulation isn't perfect. The best strategy for playing this game therefore is to look for indications as to whether I'm the real me or the simulation when the question is posed to me, and choose accordingly. Am I floating in a sensory deprivation tank being asked my choice by a disembodied voice with no recollection of how I got there and no memory of my childhood? In that case maybe I'm the simulation, so my answer is that I'll choose just one box. Is it an ordinary day of my life and a plausible setting with all of my faculties and recollections intact? Then I'll assume simulated me had my back and take both boxes.

Take it to a charity shop or thrift store near you that accepts donations of electronics so that it finds its way to some smart kid who wants to teach himself or herself about computers.

For another example of betrayal, one of the cronies in Katherine the Great's court always gave a dog to his girlfriends whenever he started a new relationship. Then if the dog ever greeted some other guy familiarly, he inferred he was falling out of favor. He probably learned that trick when someone did it to him, because he would let the other guy know how he was rumbled before graciously bowing out.

I worked for a company that made dedicated FPGA based hardware for high frequency trading by deep-pocketed customers. You can certainly implement trading strategies running directly on the board with crazy fast turnaround times, but if a retail trader could benefit from them we all would have quit our jobs and become independent high frequency traders. Interestingly, at that point the Linux network stack becomes a bottleneck so you'll want to go for a proprietary alternative whose name I don't remember any more (not cheap), which I imagine might also apply to a Mac, but that's neither here nor there unless you have a server in close physical proximity to the exchange. Meta-advice: If you want to learn about FPGAs as a matter of interest, more power to you. Otherwise, skip the bikeshedding and learn enough about financial markets to find a niche where you might have an edge.

FreeTube [1], and yt-dlp [2], especially in combination with a ready supply of VPNs. Switching them around to avoid being blocked by Google reminds me of adjusting the tuner for better reception on an old analog tv. Infant me might have imagined a malevolent being who inhabits the airwaves deliberately causing interference, and in the world we've created since then that's not far from the truth. Many thanks to the developers tirelessly compensating for Google's frequent deliberate breakage.

It happened to me too, and I was unable to verify myself by any acceptable means due to being based in a country other than that of my passport. Having been redirected somewhere else for the identity verification onboarding, I think the process is outsourced by Hetzner to a firm of security specialists apparently oblivious to edge cases. Nice work if you can get it.

There's some other specific character besides spaces that's also not permitted in passwords. It's a normal printable ascii character but I can't remember what it is any more, and sometimes it's not caught. Let's hope nobody signs up with it by mistake.

If they're geo checking IP to passport, I also would fail.

That cloud of laser-cooled beryllium ions would probably be great for overclocking.

I have, and the technical support representative at Proton confirmed it, but not without implying that it was my fault for using rclone. I asked the official recommendation for Linux users to do automated or scriptable backups onto a Proton drive and the answer was that some kind of SDK was planned for the future. Proton drive stopped working completely with rclone shortly after that, which was about two months ago.

I want to be happy with proton but their poor linux support across all their products makes it difficult.

To be honest, all consumer cloud storage providers get touchy when you access them via API.

Dropbox API refuses to sync certain 'sensitive' files like game backups (ROMs or ISOs). There is no way for Dropbox to know if you own the game and thus can own a backup, they just play file police.

I know everyone says SK combinators can express any computable function, but I don't get it. How do we write this function foo in terms of SK combinators alone? Is there some obvious programming trick I'm missing that makes it trivial? (It wouldn't be the first time.)

foo(x) = if (x == K) return S else return K

That's not a computable function. Function equality (x==K) is undecidable.

And that's covered in the last chapter of To Mock a Mockingbird (this submission prompted me to pull it off the shelf this morning).

Just postulate function extensionality and move on with life. :D

Are you asking how to do a if else statement?
