Oh, look a Borg CVE has just landed in my Debian security inbox.

I have currently settled on borg for backups personally, combined with some gruesome ssh hackery to let me do pull backups of external machines using ssh tunnelled sockets back to a backup server which is not reachable from the wider internet. These days I might just use tailscale to set up a VPN & pipe the backup straight over that without all the ssh shenanigans but the system I have works. You can also use borg to talk directly to rsync.net at special nerd rates: https://www.rsync.net/products/borg.html Bring your own support!

NB. Last time I looked at this, borg’s cryptography was somewhat suspect. Not actually broken, but definitely not using best practices. Restic is better, but at the time I was looking restic didn’t compress backups so it was a non-starter for me. These days restic does compression as well so is probably the right default choice. Borg2 has a rewritten encryption layer which supposedly fixes all the problems pointed out by cryptographers with Borg1, but it hasn’t hit a release version yet & is still in beta.

The seed oil / sunburn thing is something I saw going around online just this week. Is there /anything/ behind it at all or is it just another chunk of LessWrong science by anecdata?

High-end stats is kind of Taleb’s thing, so he gets to be as insufferable as he likes dunking on IQiots imo.

[–] [email protected] 4 points 2 years ago

Yeah, he needs an editor. But the relentless dunking on IQiots is worth the verbiage imo.

This Twitter post from the guy who was synthesising the stuff in the US seems convincing: https://twitter.com/andrewmccalip/status/1689476909208600576

Not a superconductor - the hints of superconductor-like properties were due to a combination of iron contamination in the Pb forming iron fragments which (surprise!) show ferromagnetism & Copper Sulphide which shows a very similarly anomalous temp/resistivity profile (but is not a superconductor).

The most likely outcome (i.e., not a superconductor, lab error due to honest scientists being fooled by their own experiments) seems to be probably the true one.

Here’s another classic non sequitur: https://www.reddit.com/media?url=https%3A%2F%2Fi.redd.it%2Fwayy8oc30ygb1.png

Why does it tend to collapse into pseudo-religious babble when it goes off the rails? I guess it tends to be very repetitive, so maybe the training set has turned religiosity into some kind of attractive basin in the output space? Once in, you can’t get out again.

It’s as if it’s a markov chain with a bigger token space to work from. Oh wait.

He got publicly embarrassed by a disabled person, I know that much. But he would have been like this anyway.

[–] [email protected] 4 points 2 years ago

Agreed, I read this as saying that the cop would otherwise have got away with it & that this was a /bad/ thing.

Also, the experimenting on babies thing is hilarious.

Ah, that’s why you were asking about it?

& yeah, a naïve digital physics model is going to run slap into issues with both Bohmian constaints on locality & the fact that it’s unlikely your lovely new model predicts anything taking the current model and ignoring all the philosophical problems (because they don’t actually matter) fails to predict. I would be very surprised if Wolfram isn’t aware of this.

There are some intriguing hints of something deeper in the holographic principle, which suggests that everything that happens inside a bounded region of space can be inscribed on the surface of that volume: You could imagine some kind of process occurring on the surface of a volume that’s connected to the interior in ways that would be non-local from the interior’s POV, but might be entirely local on that surface.

But none of this is developed anywhere near the point that you can wave at one of Wolfram’s favourite automata & go “well, if you run that on the surface of a volume then Quantum Physics & Gravity drop out naturally.” It’s all handwaving & “it might work like this” & a bunch of very theoretical physics that doesn’t, at the current time, actually correspond to real world physics very much, if at all.
