Most of the videos are crap, but the following ones almost killed Ciro Santilli of laughter:

Monty Python has a few precursors to the "random famous people mixed together compting" format, although not in the rap fight format:

These are some users Ciro Santilli particularly respects, mostly due to their contributions to systems programming subjects:

Ciro also really likes the following users, a bit less like Gods, and bit more like friends:

Other interesting people:

Ahh, this dude is just like Ciro Santilli, trying to create the ultimate natural sciences encyclopedia!

____
In 1995, Weisstein converted a Microsoft Word document of over 200 pages to hypertext format and uploaded it to his webspace at Caltech under the title Eric's Treasure Trove of Sciences.
____

For the most part, a great pseudo-country to live in with lots of cultural diversity, art and safety.

However, Europe is in economic decline after all its Jewish and German geniuses fled in/after World War II and due to having more than one natural language is bad for the world.

Ciro Santilli moved to Europe in 2010.

This is Ciro Santilli's name for the idea that we should not have structured degrees at university that require entry exams, only tests that anybondy could take, likely for free, and then they would just have proof that they know the stuff for e.g. teachers that care about a subject while selecting students to work with them in research.

We just need control rooms where someone can watch students for cheating. Multiple different exams can be taken in the same room of course, students just have to sign up in advance. The exams should happen regularly depending on demand. E.g. extremelly common subjects should happen every month, and highly specialized ones every 6 months or 1 year.

Questions should be always taken from an open question pool which also contains answers, thus allowing anyone to effectively study for it.

How many questions can you actually come up with about a given non research subject, right?

We then make an API available, so that students can grant access to specific results to anyone they choose, or even make the results public for anyone to see. This way the people that care about the exams can just machine learn what exams correlate with their desired performance.

Some anecdotes.

Ciro Santilli never splits up functions unless there is more than one calling point. If you split early, the chances that the interface will be wrong are huge, and a much larger refactoring follows.

If you just want to separate variables, just use a scope e.g.:

int cross_block_var;

// First step.
{
    int myvar;
}

// Second step.
{
    int myvar;
}

Ciro has seen and had to deal with in his lifetime with two projects that had like 3 to 10 git separate Git repositories, all created and maintained by the same small group of developers of the same organization, even though one could not build without the other. Keeping everything in sync was Hell! Why not just have three directories inside a single repository with a single source of truth?

Another important case: Linux should have at least a C standard library, init system, and shell in-tree, like BSD Operating Systems, as mentioned at: Section "Linux".

This doesn't do a hole lot. Ciro Santilli wouldn't really call it a web framework. It's more like a middleware. Real web frameworks are built on top of it.

Examples under: nodejs/express:

A live example on Heroku can be seen at: github.com/cirosantilli/heroku-node-min

Creator of QEMU and FFmpeg, both of which Ciro Santilli deeply respects. And a bunch other random stuff.

What is shocking about Fabrice this is that both are insanely important software that Ciro Santilli really likes, and both seem to be completely unrelated subjects!

Google made billions on top of this dude:

At last but not least, Fabrice also studied in the same school that Ciro Santilli studied in France, École Polytechnique.

It is a shame that he keeps such a low profile, there are no videos of him on the web, and he declines interviews.

Another surprising fact is that Fabrice has not worked for the "Big Tech Companies" as far as can be publicly seen, but rather mostly on smaller companies that he co-founded: www.quora.com/Computer-Programmers/Computer-Programmers-Where-is-Fabrice-Bellard-employed

And he's also into some completely random projcts unsurprisingly:

Ciro Santilli managed to port it to Sequelize for PostgreSQL as shown at: github.com/cirosantilli/feathers-chat/tree/sequelize-pg

Feynman became a terrible womanizer after his first wife Arline Greenbaum died, involving himself with several married women, and leading to at least two abortions according to Genius: Richard Feynman and Modern Physics by James Gleick (1994).

Ciro Santilli likes to think that he is quite liberal and not a strict follower of Christian morals, but this one shocked him slightly even. Feynman could be a God, but he could also be a dick sometimes.

One particular case that stuck to Ciro Santilli's mind, partly because he is Brazilian, is when Feynman was in Brazil, he had a girlfriend called Clotilde that called him "Ricardinho", which means "Little Richard"; -inho is a diminutive suffix in Portuguese, and also indicates affection. At some point he even promised to take her back to the United States, but didn't in the end, and instead came back and married his second wife in marriage that soon failed.

Richard's third and final wife, Gweneth Howarth, seemed a good match for him though. When they started courting, she made it very clear that Feynman should decide if he wanted her or not soon, because she had other options available and being actively tested. Fight fire with fire.

FFmpeg is the assembler of audio and video.

As a result, Ciro Santilli who likes "lower level stuff", has had many many hours if image manipulation fun with this software, see e.g.:

As older Ciro grows, the more he notices that FFmpeg can do basically any lower level audio video task. It is just an amazing piece of software, the immediate go-to for any low level operation.

FFmpeg was created by Fabrice Bellard, which Ciro deeply respects.

Resize a video: superuser.com/questions/624563/how-to-resize-a-video-to-make-it-smaller-with-ffmpeg:Unlike every other convention under the sun, the height in scale is the first number.

This is the kind of mind-bending argument twists that Ciro Santilli loves. If we take out the "a real child is hurt" aspect, does it still make sense to make it illegal?

Of course, hentai of young-looking girls has already existed since forever. Bit with newer image generation methods in the 2020s used for computer generated child pornography, especially sometimes photorealistic text-to-image generation, things are taken to another level.

This is a small fork of activatedgeek/LeNet-5 by Ciro Santilli adding better integration and automation for:

Install on Ubuntu 24.10:

Download and extract MNIST train, test accuracy, and generate the ONNX lenet.onnx:Extract MNIST images as PNG:Infer some individual images using the ONNX:Draw on a GUI and see live inference using the ONNX:TODO: the following are missing for this to work:

Ciro Santilli used to use file managers in the past.

But he finally converted to a shell cd aliases that auto-ls: github.com/cirosantilli/dotfiles/blob/a51bcc324f0cff0eddd4c3bb8654ec223a0adb7b/home/.bashrc#L1058

In this example we attempt to inject React elements into statically rendered HTML coming from the server, and properly hydrate them.

Questions by Ciro Santilli:

Bibliography:

This is a minimal reproducible example for the terrible problem of external effects applying twice to refs for effects that are not idempotent and thus blowup if applied twice.

The issue is currently discussed at: react.dev/learn/synchronizing-with-effects#step-3-add-cleanup-if-needed (archive) which says "you need to cleanup the thing yourself". web.archive.org/web/20240720100401/https://react.dev/learn/synchronizing-with-effects#subscribing-to-events is also says that for the specific case of addEventListener.

But that's annoying! Can't we just somehow tell if we applied twice or not to avoid having to implement a cleanup? What if a third party system does not provide a cleanup at all?

Is the correct solution to just just have a useEffect with empty dependency list? Seems to be good according to posts and to ESLint!

Tried to do a React only reproduction at: react/ref-twice.html.
