Ciro Santilli @cirosantilli 37

Most of them use titles from TV Tropes.

Ciro Santilli used to read books when he was younger (Harry Potter up to the 4th, Lord of the Rings), but once you are reading code, technical articles and news the whole day, you really just want to watch videos of people doing useless things on YouTube to rest, enough text.

Books are slow. No patience. Need faster immediate satisfaction.

Paradoxically Ciro feels like he's becoming a writer of sorts though, one semi independent section/answer/piece of knowledge at a time.

Writing is not just giving out information. It is re-feeling it.

Ciro Santilli's favorite religion. He does not believe fully in it, nor has he studied it besides through brief Wikipedia and Googling.

Ciro likes Buddhism because it feels like the least "metaphysical explanations to things you can't see" of the religions he knows.

Rather, it feels more like "a plausible theory of the mind" and highly compatible with physics.

Ciro also believes that there is a positive correlation between being a software engineer and liking Buddhist-like things, see also: the correlation between software engineers and Buddhism.

Very good! Goes up to the Dirac equation.

There were apparently some lecture videos at: web.archive.org/web/20030604194654/http://physicsstream.ucsd.edu/courses/spring2003/physics130a/ as pointed out by Matthew Heaney^[ref], .mov files can be found at: web.archive.org/web/*/http://physicsstream.ucsd.edu/courses/spring2003/physics130a/*, but we were yet unable to open them, related:

This theorem roughly states that states that for every quantum algorithm, once we reach a certain level of physical error rate small enough (where small enough is algorithm dependant), then we can perfectly error correct.

This algorithm provides the conceptual division between noisy intermediate-scale quantum era and post-NISQ.

For some reason they attempt to make a single chip on an entire wafer!

They didn't care about MLperf as of 2019: www.zdnet.com/article/cerebras-did-not-spend-one-minute-working-on-mlperf-says-ceo/

Gospel of Matthew 7:13:

Ciro Santilli really likes this one, because he feels that where many people go, it is useless to go again. It is much better to explore that which few can do, but which many will need.

Water Margin also comes to mind. And also A story of floating weeds.

Also known as being hipster.

Quora is crap in many, many senses, but in part due to some bad Stack Overflow policies, it is the best crap we've got for certain (mostly useless) subjects. Until OurBigBook.com dominates the world.

The worst thing about quora is that you cannot subscribe only to certain subjects on your feed. Quora just keeps pumping shit you never subscribed to, no matter what. Ciro, for sport, unfollowed every single idiotic subject it was proposing, but it didn't work, sooner or later Quora just keeps pumping more shit back. Mind you, some of that shit is fun. But it's still shit. Though on second thought, YouTube also randomly decides to reset Ciro's humongous "don't recomend this shitty channel" choices from time to time, which is not much different...

Other terrible things, they just seem to have an incredible ability of making the website worse and more annoying over time! Truly amazing:

Quora is getting so bad that it is basically being killed by Reddit, especially after they lifted the 6-month hard thread lock...

Very easy to use and pretty powerful MIDI creator!!!

One of the rare audio applications actually works with PulseAudio on Ubuntu 20.04 out-of-the-box, so you don't have to turn off every other audio application!!!

Has lot's of plugins built-in just working out of the box, e.g. ZynAddSubFX out-of-the-box without doing a gazillion complex setup connections.

Most plugins are just simple toys however, ZynAddSubFX is the only super powerful one. The others are more LMMS integrate however, and seem to use a more dedicated LMMS GUI style.

TODO can you do liver performance with a virtual instrument?

If you open vmpk, you can then right click on a piano track, and go MIDI, Input and it just shows up there, and it does produce sound as shown at: www.youtube.com/watch?v=NpeP2th08ak

TODO: what about recording the input MIDI? Yes, there is a record button on the piano roll!

Sample software implementations:

The equation that allows us to calculate stuff in special relativity!

Take two observers with identical rules and stopwatch, and aligned axes, but one is on a car moving at towards the $+x$ direction at speed $v$.

TODO image.

When both observe an event, if we denote:It is of course arbitrary who is standing and who is moving, we will just use the term "standing" for the one without primes.

Then the coordinates of the event observed by the observer on the car are:where:

Note that if $\frac{v}{c}$ tends towards zero, then this reduces to the usual Galilean transformations which our intuition expects:

This explains why we don't observe special relativity in our daily lives: macroscopic objects move too slowly compared to light, and $\frac{v}{c}$ is almost zero.

OK, so let's verify the main desired consequence of the Lorentz transformation: that everyone observes the same speed of light.

Observers will measure the speed of light by calculating how long it takes the light going towards $+x$ cross a rod of length $L=x_2-x_1$ laid in the x axis at position $X1$.

TODO image.

Each observer will observe two events:

Supposing that the standing observer measures the speed of light as $c$ and that light hits the left side of the rod at time $T1$, then he observes the coordinates:

Now, if we transform for the moving observer:and so the moving observer measures the speed of light as:
