Blocked & Reported (the podcast) did two episodes on this [1] and [2] that breaks down most of the controversy. This has completely ruined me on anything even adjacent to this, like whether Koko the gorilla could actually communicate. [

How could updating the software possibly make a difference here? If the encryption is cracked, then who is to say who owns which Bitcoin? As soon as I try to transfer any coin that I own, I expose my public key, your "Quantum Computer&

Fair enough. Then maybe they should take Enterprise, though I think they'd be happier with their current replica than a dummy trainer.

Clearly the Smithsonian Air and Space Museum is a fitting place for one of the decommissions shuttles to reside. So why move it? Endeavor is located in California (at the California Science Center) and Enterprise is located in New York (at

I think there is at least something of a middle ground for almost-but-not-quite-public spaces and events. In this case the author is talking about airsoft games; it seems totally reasonable for the venue or organizer to enact policies, whet

This (and the underlying text) reads as intensly naive and an attempt to further a modern narrative completely divorced from historical context. While I don't think that we can make a definitive statement that justice in "Africa&q

Thanks for this expansion of the ideas involved. My question here is what does the COMPILE word do? What is the state of the VM / compiler / repl or whatever after it encounters that word? That "IF" is implemented in ter

A million times this. The syntax is not difficult to see, but the action seems mysterious. The article gives an example > : buzz? 5 mod 0 = IF ." Buzz" THEN ; Seems to work okay. What about immediate mode? > 1

I actually prefer a syntax that is whitespace-sensitive, but should not give meaning to whitespace. That is, the whitespace should not perform a semantic duty, but should be required to be correct. This is roughly equivalent to saying that

It's a two year old note talking about mixers and money laundering and it's being misrepresented as a new government stance against self-custody. That's why it's click bait.

This is pure click bait that relies on a deliberate misreading of a 2023 notice [1] that tries to imply that "self custody" is being attacked in any form. All that this is saying is that the government will try to track money move

This is not true. None of the Apple cases (or third party cases) give a flush finish to the entire phone. They just add a new, bigger, larger bump below the camera bump which lets the phone basically lie flat. It does not make it easier to

Have not read the underlying study but given that it is a generic nutrition and vision study, this seems like a clear case of p-hacking. At best it could be a "here is something that might merit future research". They find that on

This rings true to me -- it's hard to sell a $480 device that only displays images. Easier to sell a $500 device that is a $480 display + $20 of crappy software and sensors and speakers and compute so that buyers think they're get

Is anybody making smart glasses that are just a display? For me, the rest of the feature set verges on being anti-features. I'd much rather a very rudimentary display that my phone or another device could send relatively low bandwidth

No, go ahead and leave your home. Why wouldn't you leave your home? What if a police officer or a nosy neighbor is watching your house specifically and writes down your comings and goings? You surrender a certain amount of privacy by l

I continue to believe that privacy in public spaces is not a civil liberty and we should not be treating it as such. You have the right to be secure in your home or in private spaces, but it is your obligation to ensure that you have made a

No, with projective geometry or affine geometry you can make translation into a linear operation. But in ordinary Euclidean space translation is not a linear operation. Most obvious case that it fails is that it doesn't map zero to its

> Perhaps from graphics -- translation, rotation, reflection Maybe ... but the fact that you included translation in the list of linear operations seems like a big red flag. Translation feels very linear but it is emphatically not [1]. T

I haven't looked at Strang's approach. The "x = b / A" is a bit of a gut-punch on first look because my mind immediately tells me all the ways that that does not work. It makes a some sense once I take a second to t

by andrewla 1y ago
Maybe I was making unwarranted assumptions about the nature of your way to learn linear algebra. The approaches that I've seen invariably have to produce a sample matrix, and rotation is really the best example. The rotation matrix is

To a degree I think this is true, but it requires (at least in my experience) that you have an intrinsic grasp of trigonometry for it to make sense. If you have some complex function analysis and e^itheta then you can skirt the problem for

I have yet to encounter an approach that is not boring. You just have to power through it. This approach seems as good as any. Once you get to eigenvalues (in my opinion) things start to pick up in terms of seeing that linear spaces are act

Yes, they have measure zero. So the question becomes whether "measure" is a useful concept at all. In my opinion, no, it is not. It's just another artifact of non-constructive and meaningless abstractions. Many modern courses

Yeah, we teach it. It ends up showing up again in measure theory, assuming that anyone still bothers to teach the mostly useless Lebesgue integral instead of the gauge integral. Measure theory shows up again in probability theory if you&#x2
