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.:

For synthesized streams like but it does not seem to accept multiple fails with:
sine we can do it e.g.ffplay -autoexit -nodisp -f lavfi -i '
sine=frequency=500[a];
sine=frequency=1000[b];

'-i for some reason. So is there a way to open a file from some filter? E.g.:ffplay -i tmp.wav -i tmp.mkv -filter_complex "[0:a]atrim=end=2[a];[1:v]trim=end=2[v]" -map '[a]' -map '[v]'Argument 'tmp.mkv' provided as input filename, but 'tmp.wav' was already specified.Simple sines and variants:

CIA 2010 covert communication websites USA spying on its own allies by 
Ciro Santilli 40 Updated 2025-08-08
Ciro Santilli 40 Updated 2025-08-08Being Brazilian, Ciro Santilli was particularly curious about the existence of a Brazil-focused mentioned in the Reuters article, as well as in other democracies.
WTF the CIA was doing in Brazil in the early 2010s! Wasn't helping to install the Military dictatorship in Brazil enough!
Here are the websites likely targeting democracies based on their language and content found so far, defining a democracy as a country with score 7.0 or more in the Democracy index 2010:In English, so more deniable:"Almost democracies":Ciro couldn't help but feel as if looking through the Eyes of Sauron himself!

It is worth noting that democracies represent just a small minority of the websites found. The Middle East, and Spanish language sites (presumably for Venezuela + war on drugs countries?) were the huge majority. But Americans have to understand that democracies have to work together and build mutual trust, and not spy on one another. Even some of the enlightened people from Hacker News seem to not grasp this point. The USA cannot single handedly maintain world order as it once could. Collaboration based on trust is the only way.
Snowden's 2013 revelations particularly shocked USA "allies" with the fact that they were being spied upon, and as of the 2020's, everybody knows this and has "stopped caring", and or moved to end-to-end encryption by default. This is beautifully illustrated in the 2016 film "Snowden" when Snowden talks about his time in Japan working for Dell as an undercover NSA operative:
NSA wanted to impress the Japanese. Show them our reach. They loved the live video from drones. This is Pakistan right now [video shows American agents demonstrating drone footage to Japanese officials]. They were not as excited about that we wanted their help to spy on the Japanese population. They said it was against their laws.And we did not stop there. Once we owned their communications systems, we started going after the physical infrastructure.We'd slip these little sleeper programs into power grids, dams, hospitals. The idea was that if the day came when Japan was no longer an ally, it would be "lights out".But Austria?!
But Austria?! scene from Snowden (2016)

Each of you is going to build a covert communications network in your home city [i.e. their fictitious foreign target location written on each person's desk such as Berlin, Istanbul and Bangkok, not necessarily where they were actually born], you're going to deploy it, backup your site, destroy it, and restore it again.

Or when startups use the cheapest stuff available and randomly become the next big thing, and decide to keep maintaining the open stuff to get features for free from other companies, or because they are forced by the Holy GPL.
Open source frees employees. When you change jobs, a large part of the specific knowledge you acquired about closed source a project with your blood and tears goes to the trash. When companies get bought, projects get shut down, and closed source code goes to the trash. What sane non desperate person would sell their life energy into such closed source projects that could die at any moment? Working on open source is the single most important non money perk a company can have to attract the best employees.
Open source is worth more than the mere pragmatic financial value of not having to pay for software or the ability to freely add new features.
Its greatest value is perhaps the fact that it allows people study it, to appreciate the beauty of the code, and feel empowered by being able to add the features that they want.
And "can reverse engineer the undocumented GPU hardware APIs", Ciro would add.
While software is the most developed open source technology available in the 2010's, due to the "zero cost" of copying it over the Internet, Ciro also believes that the world would benefit enormously from open source knowledge in all areas on science and engineering, for the same reasons as open source.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
