Laser trackers (used for metrology) can also use spiral search to find retroreflectors. Although I believe newer models generate a flash of infrared and find them via bright spots in the resulting image from a camera. I imagine modern celes

Side question, but does anyone know why specifically 2^-32 is the target floor for attacker success (in footnote 3)? I found another mention of the 2^-32 target in [0], but I'm not even certain they're related. [0] https:/&#

I have used this for throwing together some models for 3D printing. I've found it very intuitive, though I'm not sure how ergonomic it would be for complex assemblies. I really like the space-key based command access and default s

Aside, but it's pretty neat that the author has been semi-regularly posting on their blog for over 20 years.

In particular, the Order-of-Magnitude section might be interesting: https://nathanmcrae.name/order-of-magnitude/

I would also toss differential evolution in the ring as a widely applicable and easy to implement technique. https://en.wikipedia.org/wiki/Differential_evolution

How do you go about positively demonstrating such a system is air-gapped?

No, 600 megatons (~E12 kg) is closer. There are E10 humans and we weigh E2 kg. More precisely: 6E1 kg * 8E9 = 5.6E11

I've run Nextcloud for years primarily for webdav file sync and calendar+contacts. It pretty much just works. That's not to say there isn't any jank, but it's mostly if you try the more obscure apps e.g. I've set up

Even though this isn't a fully-fledged industrial system, I like the thought they put into those aspects. Particularly, I want to make a homebrew PLC myself someday and the 24V IO board they made would be a nice starting point for that

The reason you would trust and FPGA more than a SoC is because putting in backdoors in an FPGA is much harder. If an FPGA is backdoored to the point where any soft core (whose layout kind be randomized to some degree) is compromised, then t

I think pen-and-paper one-time pads are an underestimated tool for private communication. Granted they are cumbersome and limited, but they provide almost perfect secrecy and bypass issues of compromised computers completely. And with some

I'm currently doing this and personally I believe the dates and names approach is best (depending on your goals). The theory is that if you have a solid grasp of the coarse details like births/deaths/major battles then when y

I think people should seriously consider using something like passphrase2pgp [0] in addition to a hardware key like this. That way you can have a brain key (hopefully generated with diceware or equivalent) to tie together day-to-day keys li

This is exactly the kind of thing I hope LLM chatbots will be genuinely useful for. Though, how often do you find it completely hallucinating endpoints / parameters etc. ?

I find a good way to link together ideas is to have them easily at hand i.e. memorized. Having a motivating problem is probably a better way to do this, but I've found that motivating problems which require concepts I would like to lea

For me it was lambda calculus. I remember in high-school going through the motions of beta-reduction but having no idea what it meant. Much later I think I finally saw an implementation of natural numbers and addition using bare lambda calc

True, but verifying proofs is usually easier (or at least more mechanical) than generating proofs. Personally I think this is the best possible use of AI: to have it generate systems that have verifiable properties in some formalized langua

I don't know how all of the factors you bring up interact, but as far as the last point: the universe is indeed uniform and isotropic at a large enough scale (~300 million ly), called, nicely enough, the End of Greatness ( https:&#x2F

I find that using Everything search ( https://www.voidtools.com/ ) makes me use the filesystem more like a tagging system. I still name files and directories meaningfully, but I don't worry about the hierarchy at all. Th

The paper addresses your first point in section 7 'Model Rationale'. Essentially, anything that is subject to self-propagation is going to tend to expansionism at a large enough scale, superintelligence or not. The only thing that

Yeah, that's an important point, but that seems to be an issue with the subject of study rather than this particular theory. At least their model has very concrete and explicit premises that could be used to reject it. Particularly the
