I remember talking to someone who had worked on reversible computing about 13 or 14 years ago, and he had said that (i) it does work (presumably that it is indeed more energetically efficient), but (ii) the state of computing was such that

I'm not even running Nightly, just switched to 57 beta. It's a big improvement on 55 & 56 (which already felt faster than older versions).

Not an astrophysicist, but my guess is both gravitational and EM waves travel at the speed of light and there should not be a big delay. The limiting factor is the duration of the astronomical event in question, which may only be minutes o

I like having darkroom mode. Don't think macos/nightshift has that yet.

Very much off-topic: I understand the post and the present discussion are not about Kolmogorov's scientific work, but I could not resist pointing out that in addition to all the great things Scott mentioned, Kolmogorov also made signif

If you like this sort of thing, and haven't heard of the McGurk Effect before, take a look at this: https://www.youtube.com/watch?v=G-lN8vWm3m0 .

I think you're onto something (about C extensions). There was a time, before clang became default on osx, when Apple deprecated nested functions (and perhaps others) in their version of gcc, and afaik no one complained. So I may well

Off-topic, but nested functions are one of my favorite gcc extensions.

The statement is not as non-sensical as it sounds. Hagfish are actually quite interesting evolutionarily. See e.g. https://en.wikipedia.org/wiki/Hagfish .

I sure hope someone has a plan to at least preserve all this data, if not to look at it. Does anyone know?

Me too, most especially if the email is from a student. I imagine the same goes for many of us who write research papers.

You may already know about Guile-Emacs, but in case not, take a look at https://www.emacswiki.org/emacs/GuileEmacs . Guile is not Racket, or more precisely Racket is no longer exactly Scheme, but they are closer to ea

I don't mean to imply d(n) does not drop off exponentially (as it should), only that it has a sharp drop-off before the exponential scaling sets in, rather than a steady exponential all the way. Also, if you equip an Ising model with G

The "cut-off" phenomenon is dynamical, not involving changes in parameters. The idea is that if you start a (irreducible aperiodic) Markov chain with initial condition drawn from a non-stationary distribution, and you compute the

To clarify, the relevance is that deriving the vector field from the Hamiltonian requires taking partial derivatives; see the linked section from Structure and Interpretation of Classical Mechanics (SICM) by Sussman and Wisdom w/ Mayer

All this is true, but while we( ) used to shop regularly in Chinatown markets (back when we lived close to a Chinatown, anyway), we would not eat anything raw except for fruits. Any vegetables or meat to be eaten raw or undercooked, we wou

The real power of this isn't just differentiating a given function; as others have pointed out, you can do this in, e.g., C with function pointers. Having first-class procedures and closures means you can actually return the derivat

My impression (from talking to engineers at my local electric utility here in the southwest US) is exactly that: renewables can be unpredictable, and not always available when demand is high. NG generators, unlike coal or nuclear, are rela

Ditto! This has been my workflow for a couple years now. LaTeXit is great. Almost completely replaced Beamer for me. However, if the integration is good, and I could do it all in Keynote, it would be even better.

The Berryessa station, at least, should be bikable from a decently-sized residential area, not to mention reachable by light rail or bus. We'll see what people actually do.
