OurBigBook.com Consulting Updated 2025-07-16
Start with consulting for universities to get some cash flowing.
Help teachers create perfect courses.
Choose a domain of knowledge, generate perfect courses for it, and find all teachers of the domain in the world who are teaching that and help them out.
Then expand out to other domains.
TODO: which domain of knowledge should we go for? The more precise the better.
- maths is perfect because it "never" changes. But does not make money.
- computer science might be good, e.g. machine learning.
Open University Updated 2025-07-16
Not really dedicated to open source course material, nor to free courses...
The "Open" in its name only made sense in the 60's, when it was founded, nowadays, there isn't much about this institution that is very different compared to traditional Oxbridge. "Cheap more online university" would be a more adequate name for it.
A system that would truly live up to the name "Open" in the year 2020 is the one described at the ideal university by Ciro Santilli.
Wikipedia even says that the initial focus was on broadcasting learning material on television and radio, so what happened to that now that we have an even more powerful on-demand tool called Internet!
They even created their own MOOC website, FutureLearn. But www.freecodecamp.org/news/massive-open-online-courses-started-out-completely-free-but-where-are-they-now-1dd1020f59/ mentions:OMG. God why.
The course content is still free to access, but it’s only available for the duration of the course, and for two weeks after it ends.
A few open sources at: www.open.edu/openlearn/free-courses. The 5-hour course on particle physics says it all. Stated as of 2023 at www.open.ac.uk/about/open-educational-resources/openlearn/free-learning:
www.youtube.com/watch?v=Pj0rbafFBak What's an Open University Degree Like? by Luke Cutforth (2021) mentions that it is more autodidactic/online, and it encourages part time learning.
youtu.be/rsWwffX-u0A?t=99 Open University - How does it work? by Matt Greg Vlogs (2017) shows that they do have their own custom institutional material. And it is not open???? Please. youtu.be/rsWwffX-u0A?t=222 mentions that there is no entry exam, and you can change your courses at any time, that is good at least.
Israel apparently also created their own version in the 70's inspired by the British one: Open University of Israel. Same story it seems.

E.g., as of 2020, their help login help.openstreetmap.org/ shows MyOpenID as an option, which was discontinued in 2014, and not Google OAuth.
They do still seem to have a bit more activity than gis.stackexchange.com/questions/tagged/openstreetmap on Stack Exchange.
Complaints:
- Transliteration is off by default!...... wiki.openstreetmap.org/wiki/Translation You just have to learn all scripts ever. Good luck with the Chinese characters. Genius.
- In order to see information about places, you have to click "Query features" on the toolbar first. Who made such a terrible UI? Direct click is a much, and so easy to implement?
- It is impossible to discern different types of paths and other walking path symbols, the symbols are too small, and just scale down to a line no matter how much you zoom in.
- Power lines are way too visible. While that is kind of cool, it is useless and distracting to most people most of the time.
- No street-level imagery...: help.openstreetmap.org/questions/1178/adding-photos
- No aerial imagery: help.openstreetmap.org/questions/6849/how-can-i-see-the-aerial-imagery-without-editing-the-map But that is kind of understandable, as that one might not be free.
- No restaurant ratings: help.openstreetmap.org/questions/64852/ratings-for-pois because it is "Subjective". OMG those people, such a huge value powerhouse wasted.

Holy crap amazing list of Guqin pieces by the guy for MP3 download! www.silkqin.com/06hear.htm And the explanations are insane. What a dude. Ciro Santilli's hero.

Edit: he uploaded a bunch of videos of him playing live in 2020! www.youtube.com/user/silkqin/videos
John focuses on playing the tunes in a "historically informed performance", in particular using silk strings rather than metal ones which are used by most modern artists: www.silkqin.com/08anal/hip.htm

And of course, 4chan just takes that to a whole new level, usually closing on the same day, and then getting deleted within a week. Why would anyone contribute non-illegal content to that king of system?!
Ridiculous, so when new information comes out, we just duplicate all the old comments on a new thread again?
Remember, Ciro Santilli is the Necromancer God.
Onion service Updated 2025-07-16
This is a way to host a server that actually hide the IP of the server from the client, just like Tor hides the IP of the client from the server. Amazing tecnology!
This is why it enables hosting illegal things like the Silk Road: law enforcement is not able find where the server is hosted, and take it down or identify the owner.

www.youtube.com/watch?v=tq7sb3toTww&list=PLxBAVPVHJPcrNrcEBKbqC_ykiVqfxZgNl&index=19 mentions that it is a bit like a dot product but for a tangent vector to a manifold: it measures how much that vector derives along a given direction.

Good documentary about it: Nick Leeson and the Fall of the House of Barings by Adam Curtis (1996).
One is reminded of Annie Dookhan.
Network switch Updated 2025-07-16
A switch is a box with a bunch of Ethernet wires coming into it:Except that it doesn't have to be Ethernet, e.g. it would also be a Wi-Fi.
+--------------------+
| +-+ +-+ +-+ +-+ |
| |1| |2| |3| |4| |
| +-+ +-+ +-+ +-+ |
+--------------------+What the switch does is:
After the destination is found, a confirmation is somehow sent back to the switch, which then learns which wire to send each MAC address to.
A switch is a bit like a router but it is a bit dumber/operates at a lower level: it basically operates only on MAC addresses, not on IP addresses.
The Internet service provider boxes most people have at home combines a switch for the local network and a router for the ISP communication.

“Especially my father. He was doing most of it and he is a savoury, strong character. He has strong beliefs about the world and in himself, and he was helping me a lot, even when I was at university as an undergraduate.”An only child, Arran was born in 1995 in Glasgow, where his parents were studying at the time. His father has Spanish lineage, having a great grandfather who was a sailor who moved from Spain to St Vincent in the Carribean. A son later left the islands for the UK where he married an English woman. Arran’s mother is Norwegian.
One of the articles says his father has a PhD. TODO where did he work? What's his PhD on? Photo: www.topfoto.co.uk/asset/1357880/
