The Entire Criterion Collection Supercut by Reckoned Opinions

Featured at: www.reddit.com/r/criterion/comments/13x14he/the_entire_criterion_collection_all_1190_spine/ Holy crap, how!The greatest advantage of it being that it has the likely largest desktop user base, and therefore the highest likelihood that your problems are solved on Ask Ubuntu, and goes together with Ciro's philosophy that "people should do everything in the same way to factor stuff out", especially the open source losers.
Ciro considers that the killer flaw of Ubuntu, and most desktop distros of 2020, is that no one under the Sun knows how to build them fully from source: Linux distribution buildable from source. This is why Ciro based the Linux Kernel Module Cheat on Buildroot, see also: Linux distribution buildable from source.
However it did not happen on Lenovo ThinkPad P51 (2017) also on Ubuntu 23.10 which had been upgraded several times from God knows what starting point... At first one had X11 (forced by Nvidia drivers) and the other Wayland, but moving to p14s X11 changed nothing.
Both were running GNOME Display Manager.

Ciro Santilli 37 Updated 2025-07-16Crazy shady crypto people seem to like Ciro Santilli, so this is in order.
Giving to Ciro Santilli is the worst possible way to launder your money, as donations amounts are clearly publicly disclosed (though not donor identities if they with to remain anonymous), and clear records kept of every donation made (including private note of donor identities if known). Also suspicious donations are promptly reported to the authorities.
Donation refunds upon donor's requests are only made at our discretion, and may be declined, unless required by law of course. This is to reduce the risks of us unknowingly serving as money mules or aiding money laundering.
Ciro Santilli believes that he is not require to report large donations to either:But note that Ciro will preventively report if there are any further suspicious aspects to any donations received.
- charities have to report anonymous donations of £25,000 or more as "serious incident", but Ciro Santilli does not have a registered charity: www.gov.uk/guidance/how-to-report-a-serious-incident-in-your-charity, related: docs.ourbigbook.com/project-governance
- dealers selling goods over 10,000 euros for cash must make a Suspicious Activity Report (SAR) www.gov.uk/guidance/money-laundering-regulations-high-value-dealer-registration. However Ciro Santilli does not sell any goods, only provides services, and services are excluded from the report requirements
Sponsor Ciro Santilli's work on OurBigBook.com 1000 Monero donation by Ciro Santilli 37 Updated 2025-07-16
Ciro Santilli 37 Updated 2025-07-16On 2024-03-18, Ciro Santilli received an anonymous 1000 Monero donation (worth ~126k USD at the time) to his self-custody wallet, which pushed him over his public plea for 100k USD goal to quit his job for one year.
The transaction ID was
5c6af4df39021f3a4a053ef169c9b397e6d6bf6c7e557d3f08e4e1675d7d3eed to self hist custody wallet with address 47kzoCeRMTohJhADejtsGmGimvQKzNsuST7u2aVhAD1VX5WDbh3v1FPUoJoTK3NTJVUgAM3dWCqC4Tmp9KSQaJi6GGYWgYn. This is a roof generated by his Monero wallet: InProofV2AVFBmFhofH4GoG5NsaDutkdNWRTaEhuFgHpHTkpprRmuZ54B8FdUwFp71gqfp2jJpDUrhB3GCzZ2p8CNbh2TW1Z88ShmYWEwtkZFLccEMw9PhH3vWcMVo9mKaRsH3WgJXqq9.Since this donation is so huge, it deserves some comments and a bit of a retrospective. The path to this donation has been an interactive one, and it is described below.
After starting the OurBigBook Project, Ciro started the sponsor Ciro Santilli's work on OurBigBook.com page on cirosantilli.com and setup some donation methods to help support the project, and possibly try to capitalize a bit on Ciro Santilli's Stack Overflow contributions.
His sponsors are absolutely crazy amazing people, but Ciro simply could attract a large enough amount of small sponsors to reach life changing amounts under those circumstances. This is partly due to Video "And I am not and never have been 'familiar' scene from The Big Short (2015)".
As such, Ciro came to realize more and more that the best approach would be to reach out to a smaller number of rich people, given that the things he works on niche, but may appeal to a particularly wealthy tranche of the population: STEM people. Other experiences and ideas that contribute to this realization are:
- the creation of the OurBigBook Fellowship, which as of writing consisted of a single donation. During this exercise, Ciro Santilli gave about 2k USD to help a promising Brazilian student. In doing so, he understood a lot about what goes on inside a "rich person's" head when considering a donation
- it is hard to decide who to donate to and find those people. In part because as soon as you create a public donation system with an application process, people will game the fuck out of it. Perhaps the Lost Horse LLC approach of "they find you" is the best?
- it is basically impossible to donate more than 1% of your net worth if you have a family. Even 1% you may be discouraged about. Perhaps with reason due to previous bad donations they have made.
- the increasing wealth inequality of this world, perhaps one of the greatest problems we now face
Then, whenever a larger donation would come through and surprise Ciro, he would improve his sponsor page statements. First a private 150 USD by an awesome sponsor. Then the 2023-09 ~810$ Bitcoin one. Finally came the 2023-11-20 100 Monero one. And it was that one that pushed Ciro to start his "100k USD = 1 year campaign".
Finally on 2024-03-13, Ciro received an anonymous 10 Monero donation to self-custody wallet. He had clearly stated that one should make a test donation to that wallet before the big one, so 10 Monero felt like it could be the test one. Ciro communicated the reception at: mastodon.social/@cirosantilli/112112988286298258 and twitter.com/cirosantilli/status/1769464788009066710:
I cashed out 10 XMR on @AgoraDesk for ~1,375 USD, and kept some change in the wallet for fun. This donation confirms that my self-hosted wallet and cash-out work just fine, so feel free to drop those millions whenever you want Mr. Anon :-)
Over the next few days, Ciro checked his wallet more often than his previously self imposed once a weekend max, and as expected, he found the big one on a slightly despaired around midnight sleepless night (partly due to parenthood). He was feeling particularly bored and a bit sad with his work life that night. And there it was. 1000 Monero on the wallet. Needless to say, not much sleep was done on that evening!!!

The following days were also tense, with Ciro having a trial by fire on selling large amounts of Monero on the UK, which is not trivial as it had been banned from all major exchanges. But he managed. Further notes on that at: www.reddit.com/r/Monero/comments/17arz9f/converting_xmr_to_gbp_in_the_uk/. Ciro also decided to keep about 200 Monero around just for fun as a crazy moonshot.
Another major factor likely Ciro having published his article: Section "Cool data embedded in the Bitcoin blockchain" in 2019. This is something he wrote entirely for fun during an intense 3 week side-time binge in 2019, though some large updates were made later on. It was this article that likely some crypto-dude attention to Ciro Santilli's profile. As of 2024, there is said to be about 20 crypto billionaires, so perhaps there are about 2000 crypto 10 millionaires[ref], which is the minimum net worth for a donation of 100k USD to be feasible (1% mark). And perhaps a reasonable number of them are just nerds who got rich, and want to improve the world. There are two lessons from this:
- follow your instincts, always. If something seems mega fun and quick, do it!
- making money from a few rich people (or entities like organizations) is easier than working for a bunch of poor people, because you have to convince less people. If you reach many poor people however, things are much more stable as you can lose a few customers and still be fine
Another factor in the donation, Ciro Santilli believes, is that many rich people thing that education is bullshit. Many successful people are neurodiverse and as such, it is only natural that a large number of rich people want to improve our educational system, which tends to be the very epitome of "boring and average normality" which Ciro Santilli so much detests. This can also be seen in people such as:
- Michael J. Saylor and his Saylor Academy
- Peter Thiel and his Thiel Fellowship

Amazing reactions from the Monero Reddit community: www.reddit.com/r/Monero/comments/1brryao/ciro_santilli_received_a_1000_xmr_donation_to/These people have some serious trust issues!!! Perhaps not surprising from a privacy coin community. Ciro's Twitter post: twitter.com/cirosantilli/status/1775961945193017790

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.
