This is not so crazy - this was exactly the progression in screw drives. First came slotted screws (2-fold rotational symmetry), then Phillips/posidrive/Robertson (4-fold), and now…

I think the paper is a satire on "evidence-based medicine" - a framework which insists upon randomized controlled trials as the primary basis for medical decisions. Notably this is…

I guess I'm insane then... I built his pantorouter, and am half-way through his 16" bandsaw build. One good reason to build the bandsaw is that it's actually a very high-quality ma…

Or: there are a lot of people who think that they're in on a scam, but in fact are lower down the pyramid than they are told. That explanation requires no faith, and can also expla…

A place where autocorrect might be considered is in REPLs. Out of habit I still regularly write "print 'a'" in the Python REPL although I've been using Python 3 for a while. You ge…

Looking at the documentation - einops seems to only implement operations on a single tensor, so it's quite far from a general replacement for einsum, which can perform tensor-produ…

The idea of using a multi-agent game, rather than minimizing a single loss function, is already used in GANs - and there it seems to be an very powerful generalization of optimizat…

Not at all serious but... maybe all electrons have the same mass, charge, etc. because there is only one electron, bouncing backwards and forwards through time. As it passes backwa…

I went to one of these Sunday dinners about 5 years ago. I was living in Paris and taken there by friends - who didn't explain the concept to me in advance. So I found myself in so…

Maths notation can be wonderfully concise and precise, so it worth thinking about following it closely when programming. One of my favorite examples of this is the numpy `einsum` c…

This is a very important idea. On a global scale this idea has been codified as "climate stabilzation wedges": https://johncarlosbaez.wordpress.com/2010/11/16/stabilizatio... Each …

Thanks for correcting my embarrassing error! It's too late to edit my comment, but indeed x4 is the lower bound.

In my opinion it is disingenuous to call any supersonic aircraft sustainable. Independently of any clever aerodynamic design to moderate the drag coefficient, aerodynamic drag alwa…

The reason those are all "f"s is that they are all versions of the same thing: the function mapping features to outputs, or approximations of it. The capital "F"s refer to random v…

Indeed, it seems like a pretty subtle distinction. Given sufficiently bright light, sunflowers would certainly pass the behavioral experiment done here (which is very nicely summar…

Perhaps even more significant is that Uber gave you the price of the trip in advance . With regular taxis you had to guess, and if you weren't familiar with area, you best guess mi…

While I understand the desire for a unified Python ecosystem as much as anyone - this kind of pettifogging is not going to convince anyone to switch to Py3. Consider if the authors…

The red block reminds me of the monster in the film "It Follows". It very slowly but relentlessly heads straight for you wherever you are. Surprisingly unnerving.

This is a really great tool - the kind I didn't even know that I needed until I was given it! One question, does anyone here know how to interpret the GIL (Global Interpreter Lock)…

Your missing the requirement that the random sample be uniform in the sphere. That is, if the sphere is cut into any number of pieces of equal volume, the sample is equally likely …

If you can just dig and evacuate the tunnels, you can get energy-free transportation to anywhere on earth: https://en.wikipedia.org/wiki/Gravity_train

I've seen it exactly once (in a numerical analysis journal). Authors were blacked out. This was undermined almost immediately when the authors wrote in the introduction "... follow…
