Clojure is a fantastic language, but I have always missed a quick interactive shell where you can easily explore the language, using tab-completion and viewing the documentation easily in a way similar to ipython for the Python world. This

I thought about it when I read Charlie Stross getting one last year [0]. Then thought, what is essential about it? And decided to try something related, even if it was likely to be just another distraction: (defun full-screen () (in

I think the idea of knots as a basis for everything has come and gone several times. One of those were in the 90s, which is when I became aware thanks to the excellent "Gauge Fields, Knots and Gravity" by John Baez and Javier P Mu

Convenience. It will be maintained for much longer. And I'm used to it by now.

I found myself in a similar situation and also started de-googling, which is much nicer and liberating than I was fearing. I did the exact same thing with Immich (what a great software, by the way!). And in case it helps: Instead of always

I suspect you are rather referencing Abbott & Costello's "Who's on First?" :) https://www.youtube.com/watch?v=2ZksQd2fC6Y

Thanks for clarifying! FWIW, I wasn't there, but that matches exactly what I remember from that time (I did follow all the different renamings in detail).

Cool, I didn't know that. Still, the main point of the geometric algebra version is that it's not a "stitching" exercise, but a natural operation in the algebra -- and even better, an invertible one.

Just to give a brief answer to those reasonable criticisms: The mixed-grade already exists in complex numbers (it is very useful there, and even more so in geometric algebra). Differential forms are included in geometric algebra (the exteri

Well, I got sucked down the same Geometric Algebra rabbit hole, plus another "remarkably concise and intuitive way" one too, which is Clojure. So I wrote a library that can generate any GA and do all kind of fun operations (which

It does preclude it, but clojure found an arguably elegant solution to it, using recur[1] instead. As a plus, in addition to achieving the same result as tail-call elimination, it does check that the call is indeed in tail position, and als

I really like jq, but I think there is at least one nice alternative to it: jet [1]. It is also a single executable, written in clojure and fast. Among other niceties, you don't have to learn any DSL in this case -- at least not if you

I encrypt with gpg and upload the .xkdb file (itself already encrypted) to a server I have access to with scp. Not manually, and not only for this file: this is a system I have to sync the files I want in different machines, by running a li

In case it helps: In addition to "Geometric Algebra for Physicists" (whose first two chapters I'd recommend to get a nice overview), I found Hestenes' "New Foundations for Classical Mechanics" to be very good a

For sure I got significantly(?) better with classics like Spivak, Apostol, Rudin. "Real and Complex Analysis" by Rudin, and the two books both named "Calculus" from Spivak and Apostol. But also from Apostol his more conc

About the USB keyboard, that may be true only for the cheapest keyboard you could find, but basically not applicable anymore nowadays. Rather than giving you the details, let me link to this video, which is awesome at explaining it and much

Apologies to my old classmates at the university, when during the computer lab sessions I would telnet(!) to their machines and launch at random times xneko and/or xsnow. Seeing their surprised and puzzled reactions from a few rows beh

Yes, cool dude indeed! Glad you mention him, I was thinking of him when I saw this article. He visited the group where I was doing my PhD many years ago and also gave a fantastic talk on evolution, learning, and artificial life -- I was qui

Any idea of why it has been flagged? Were the ones that spread suspicion about Appelbaum flagged too? It looks to me as this would be quite relevant news.
