Ah, I see, you are objecting that you did not complete what you were setting out to do. I think that is quite noble of you to admit but at least the demo presentations were quite impressive even if they lack a certain totality. Well anyway,

Your first matrix doesn't count, but the theorem is bogus: see my counterexample above. The correct theorem is that every complex square matrix has an eigenvector. If we interpret your matrix as a complex matrix, then it does have two

> However, if v is a right eigenvector with eigenvalue \lambda, then v^T is a left eigenvector with eigenvalue \lambda, as well. Consider the matrix M = [ 0.50 0.50 ] [ 0.25 0.75 ] Clearly [1; 1] is a right eigenvector

So for example let me ask for your knee-jerk opinions based on this idea: - does a matrix have the same left-eigenvectors as its right-eigenvectors? - what is the relationship between the left-eigenvalues and right-eigenvalues? - is there a

That is genuinely a really fun way to look at it, thank you for linking this! Especially this fits nicely with Markov matrices where you have N input nodes and N output nodes and the sum of all of the probabilities coming out of one of the

So, I would say that there is a canonical isomorphism between them but that they are not quite the same. So, to take a step back, I'd say that a covector is a linear function from a vector input to a scalar output (those terms themselv

Also lots of questions emerge when one is trying to be constructive. Hiring is meant to have fidelity. Fidelity to what? To the extent there are company values, nobody explicitly “tests” for them in hiring. Certainly when I worked at US Eng

So the vision statement is on agilemanifesto.org and to a lesser extent the "principles behind the agile manifesto" on the same page. What I am challenging in the above is that there is a "lip service" given rather than

I mean it is a ️️hot-take but I don't regard scrum as any sort of subset of agile. Rather scrum emerged when big companies wanted to basically do what they were already doing, but call it agile. A framework emerged to teach these compa

He reuses a lot of his slides, the one that I have a picture of speaks about taking the boundless expansion and performing an “∞-compression” which I am taking to be a conformal rescaling of the state of the universe at infinity, but I must

Note that the zero-energy universe is highly speculative; in particular there is no good way to define the total energy confined to a volume at large scales and it's hard to say that "energy is conserved" in any way that&#x27

I mean, whether it’s deterministic is really hard. We’re talking about extensions of quantum field theory and there have existed both deterministic and nondeterministic accounts of quantum mechanics, the deterministic ones generally lagging

No, the conformal cyclic universe is weird in that there is no contraction that actually happens. Things keep expanding out into forever and that’s part of why the CCU works. What happens is that the one universe becomes really boring-looki

The fringe idea is that a heat-death universe looks homogeneous and the Big Bang also looks homogeneous and so maybe we could potentially hook up the t=0 of one universe with the t=∞ of another and get rid of the “well but it takes infinite

I just think that they have different things to teach us. Chess gives you transferable skills of thinking through problems backwards, thinking about timing and how to create time, thinking about how you might get trapped later. By contrast,

This is really fascinating to me as the article at least mischaracterizes chess. It is fascinating that it is also mischaracterizing poker and poker is much more robotic than stories have told me. That chess is less robotic, is perhaps not

Happy to see GraphViz used for these things! We tried to use it at one of my jobs but it wasn't as good as what was being rolled by hand with a tree of thousands of nodes, so we created something bespoke. But it has been in my toolkit

That's actually the deal with Thunderbird, too. Supported S/MIME and needed a plugin, Enigmail, to interface with OpenPGP. What is happening here is that the thunderbird add-on interface is changing and they decided that instead o

So in general yes, if you don’t have copyright assignment it is a lot of work to relicense. But that is not necessarily the case here... things like the MIT license (which ziglang uses) are often so permissive that you can relicense them

No this is a really important question, and it has an answer. They are called closures. They are "environments" in which variables live, each of which can have a parent environment dictated by whatever rules there are. (Some progr

I mean, you now have a few more people to go to. Like, I used to live in Kansas City, Missouri. I used to have exactly one representative I could go to, but his reelection is almost surely guaranteed as long as he wants to keep running. He

It is strange given my physics training to read this discussion. Physicists do not directly apply Occam's razor in most circumstances, and we certainly don't do bookkeeping on how many “entities” there are, and your comment illust

I do not believe they are arguing for a soul but rather just pragmatism. It's not that “measurement” has some special status as coming from a soul or something: indeed your unwillingness to see it as a normal thing that happens, such t
