Ciro Santilli just keep watching that a gazillion times whenever it showed on TV.
All action scenes are useless crap, but the premise with Ciro's precious simulation hypothesis subject, related physics and the illusion of life.
It is a shame that the key premise of using human bodies to produce energy is completely and impossibly stupid. You would obviously get more energy by directing burning the food you feed into humans.
If the film had been made later, maybe the much more plausible concept of AI alignment would would have been used instead. What a shame.

In your normal 2020 broken educational system, it is the first time at which students get an official chance to learn something advanced, and possibly prepare to go venture into the PhD desert.
A language that allows you to talk to and command a computer.
There is only space for two languages at most in the world: the compiled one, and the interpreted one.
Those two are languages not by any means perfect from a language design point of view, and there are likely already better alternatives, they are only chosen due to a pragmatic tradeoff between ecosystem and familiarity.
Ciro predicts that Python will become like Fortran in the future: a legacy hated by most who have moved to JavaScript long ago (which is slightly inferior, but too similar, and with too much web dominance to be replaced), but with too much dominance in certain applications like machine learning to be worth replacing, like Fortran dominates certain HPC applications. We'll see. Maybe non performance critical scripting languages are easier to replace.
C++ however is decent, and is evolving in very good directions in the 2010's, and will remain relevant in the foreseeable future.
Bash can also be used when you're lazy. But if the project goes on, you will sooner or later regret that choice.
The language syntax in itself does not matter. All that matters is how many useful libraries and tooling it has.
This is how other languages compare:
- C: but cannot make a large codebase DRY without insanity
- Ruby: the exact same as Python, and only strong in one domain: web development, while Python rules everything else, and is not bad on web either. So just kill Ruby, please.
- JavaScript: it is totally fine if Node.js destroys Python and becomes the ONE scripting language to rule them all since Python and JavaScript are almost equally crappy (although JavaScript is a bit more of course).One thing must be said tough:
someobject.not_defined_propertysilently returningundefinedrather than blowing up is bullshit. - Go: likely a good replacement for Python. If the ecosystem gets there, will gladly use it more.
- Java: good language, but has an ugly enterprisey ecosystem, Oracle has made/kept the development process too closed, and API patenting madness on Android just kills if off completely
- Haskell: many have tried to learn some functional stuff, but too hard. Sounds really cool though.
- Rust: sounds cool, you will gladly replace C and C++ with it if the ecosystem ramps up.
- C: Microsoft is evil
- Tcl, Perl: Python killed them way back and is less insane
- R, GNU Octave and any other "numerical computing language": all of this is a waste of society's time as explained at: Section "Numerical computing language"
- Swift: Ciro would rather stay away from Apple dominated projects if possible since they sell a closed source operating system
Old cheat on separate repo: web.
Now moving to either:
- separate files under: web-cheat/ for the boring stuff
- subsections under this section for the more exciting stuff!

Mentions that the SQUID device is analogous to a double-slit experiment.

Superconducting Quantum Interference Devices by UNSW Physics (2020)
Source. An experimental lab video for COVID-19 lockdown. Thanks, COVID-19. Presented by a cute and awkward Adam Stewart.
Uses a SQUID device and control system made by STAR Cryoelectronics. We can see Mr. SQUID EB-03 written on the probe and control box, that is their educational product.
As mentioned on the Mr. SQUID specs, it is a high-temperature superconductor, so liquid nitrogen is used.
He then measures the I-V curve on an Agilent Technologies oscilloscope.
Unfortunately, the video doesn't explain very well what is happening behind the scenes, e.g. with a circuit diagram. That is the curse of university laboratory videos: some of them assume that students will have material from other internal sources.
- youtu.be/ql2Yo5LgU8M?t=211 shows the classic voltage oscillations, presumably on a magnetic field sweep, and then he puts a magnet next to the device from outside the Dewar
- youtu.be/ql2Yo5LgU8M?t=253 demonstrates the formation of Shapiro steps. Inserts a Rohde & Schwarz signal generator into the Dewar to vary the flux. The result is not amazing, but they are visible somewhat.

Companies have been really slow to support SVG features in their browsers, and that is very saddening: medium.com/@michaelmangial1/introduction-to-scalable-vector-graphics-6450c03e8d2e
You can't drop SVG support for
canvas until there's a way to run untrusted JavaScript on the browser!SVG does have some compatibility annoyances, notably SVG fonts. But we should as a society work to standardize and implement a fix those, the benefits of SVG are just too great!
Examples:
- svg/svg.svg a minimal somewhat sane SVG:
- if the
widthandheightproperties were not given, you get the default 300x150, which seems to be set in the SVG standard:

- svg/svg.html: external image. The included file is svg/svg.svg.
- svg/inline.html: inline.
- svg/billion-laughs.svg

- svg/triangle.svg
- svg/viewBox.svg: this attribute allows you to control the default SVG
svg width=andheight=while keeping the coordinates of the drawing untouched. If theviewBoxaspect ratio differs from the width/height ratio, you likely want to play withpreserveAspectRatio, otherwise you would get white spaces by default on the generated image - CSS with SVG:
