The bummer is that the transmission is only unidirectional, but a unicycle needs bidirectional control, with very little backlash. Every economical planetary gear hub involves over-running pawls, alas.

Sorry, I'll try to be clearer. QRhi docs[1] say "The Qt Rendering Hardware Interface is an abstraction for hardware accelerated graphics APIs, such as, OpenGL, OpenGL ES, Direct3D, Metal, and Vulkan." And PySide6 includes a

Suppose I'm using PySide6 and starting to use QRhi[1]. Is there a way to compare the portability and speed of pygfx (as within PySide6) with QRhi? [1] https://doc.qt.io/qtforpython-6/PySide6/QtWidgets/QR

Sourceforge still works, and is (now) reliable. The awful DevShare malware stuff that Sourceforge started (under new ownership) in 2012 was stopped (under different new ownership) in 2016.

Thank you for sharing these links. They both worked for me (in the US); both were set to ON when I got there, and I was able to turn both OFF.

Fwiw the github page for that proposal isn't linking to what seems to be the most recent discussion *. I thought type-annotations-as-comments was a no-brainer, but it seems messy. The Sept 2023 discussion shows that it is complicated b

What a sweet film. Thank you for the link. This whole time when I heard about work on the Voyager mission I assumed there was a larger team, with fewer single points of failure.

The beautiful "Bygone Visions of Cosmic Neighbors"* touches (at 13:13) on Sir William Herschel belief in life on the sun. Fun times. * https://www.youtube.com/watch?v=LhfCietvDZo

I first learned about "leaky abstractions" from John Cook, who describes* IEEE 754 floats as a leaky abstraction of the reals. I think this is a good way of appreciating floating point for the large group of people who's exp

He actually just posted a video in which he admits he lost the plot, and forgot that the real goal is something that is fun . I hope he finds his way back to that! https://youtu.be/BpJYqC4PWEw

I love that that page is nearly the same as it when I saw it ~20 years ago. Things things are still the right way.

The author is sharing second thoughts about using the MIT license and yes, bad actors are going to break bad, but the point of licensing is to control re-use within the (enforceable) legal framework of copyright. Reciprocal licenses (thank

I'm looking forward to learning more about which one makes it easier to see how various possible changes in the data are mapped to legible changes in the visualization.

Interesting - thanks dahart (hi again!) for pointing out these references. They do seem to be missing in the Cornell report.

I believe that Daniel Huttenlocher and Pedro Felzenszwalb should be credited for the multi-pass (first X, then Y) transform based on quadratic distance: https://ecommons.cornell.edu/handle/1813/5663

I wonder if Apple will use this to annoy people who are still happily using the (admittedly old versions of) OpenGL, which has been deprecated for awhile but still working for people who want simple cross-platform graphics.

Thanks for the detailed info. I'm glad it's not me trying to craft this code. Good luck with the optimizations.

Thanks for sharing this. I was worried when I saw the rejection test at the end (around line 1749) that this could be slow, but I guess that for cases like a=0 and b=1, your code avoids that rejection ever happening, is that right? So the

Others have previously pondered this, and the related issue of how to randomly select floats in [0,1). I found this to be a helpful account: https://mumble.net/~campbell/2014/04/28/uniform-random-float
