this is nice! wonder what it would take to make it emulate a small DOS like environment. the qt py has an esp32s3, which afaik is quite a beast for a microcontroller.

from their youtube comment:

Good question. For efficiency, we try to keep commonly used terms such as letters as short as possible. Note that the words we use for letters all one syllable, whereas the NATO phonetic alphabet are mostly two syllables. The words we use for spelling are also chosen so that they can be chained together easily and quickly, eg “harp each look look odd”. Easy to say quickly without slurring

The idea that fluid is solving the Navier-Stokes equation seems like an obvious error to me - it cannot solve the equation, it simply acts a fluid, which the equation was designed to approximate.

that's his "Principle of Computational Equivalence", that natural processes are themselves computations. it's easy to see this is true in a "made-up" universe, say Game of Life, but whether our universe is computational is still an open question I think.

I don't know about the card game approach, but the author definitely has a point. I'd even argue that this is a problem in most engineering teaching, talking about different little subjects with no picture of connection or purpose.

I especially appreciate the "Simulink-like" block based visual coding style, I think it's a more intuitive alternative than textual coding in the context of systems and blocks etc.

also love the convenience of simply "adding a slider" whereas in matlab for example you have to build an "app" and add callback functions and do weird stuff to change the block parameters

apparently OBS devs don't want to share direct evidence yet and resolve it privately probably due to their GPL Cooperation Commitment. while I'm sure we all appreciate that, it would be nice to see the decompiled binaries and the exact violations, just so we can explicitly point them out and argue.

I find it VERY easy to believe that Tiktok are indeed in violation, but right now all we have are statements and a 302 redirect to Microsoft Directx download page.

maybe not the book itself, but if you read the article you'll see that even weirder stuff are banned:

The government disallows the publication of any work by Liu Xiaobo, the determined critic of the Communist Party who in 2017 became the first Nobel Peace Prize winner since Nazi times to die in prison. Again, for a time last year Chinese citizens could not type 19, 80, and four in sequence—but they could, and still can, buy a copy of 1984, the most famous novel on authoritarianism ever written. Prefer Aldous Huxley’s Brave New World? They can buy that text, too, just as easily, although its title also joined the taboo list last winter.

to me it is kinda embarrassing that Purdue administration only learned it from a news source. ofc I'm not saying they shouldve monitored students' online chatter etc, but if a group of your students actively harrass a student and you learn it by reading the news there's something wrong there.

golden. his bit about the curt richter's "hope" experiment (the one with drowning rats) is very interesting:

But then there was a talk by some guy who got up and told about experiments which were supposed to be the effect of stress on rats, on their desire to survive or something — on rats. What he had done was — I mean this is what he’d done — he described it in terms of a cylindrical glass tube, but it was a bottle. He took a jar and he put rats in the jar in water, and he screwed the lid on so that they couldn’t quite come up high enough when they were swimming to get a good breath, and they were drowning — hm? And he watched how long it took them to drown, under some kind of circumstance. Now, if that ain’t a kid fiddling around! There was nothing scientifically measured, in the sense that there was some sense to it, except that the rats got very nervous, you see, and they swam faster, or something. It was the most cruel, unnecessary, stupid thing. It was very much — except it wasn’t human beings — like the stupid kind of Nazi experiments in which they don’t exactly know what they’re doing; they’re just experimenting. Huh? It was just like a kid would experiment, God damn it, in drowning rats. It had no real scientific virtue of any kind.

a bit vague and hand wavey. also I'm baffled how the author didn't use the term "chaos theory" in the text.

I did not know Processing and Arduino shared such close origins! they're both projects I adore and I believe Arduino revolutionized embedded programming, maker culture and hobby electronics. I also appreciate that the creator persisted on their choice of open source.
