Cocos2d Updated 2025-07-16
Ciro Santilli considered this as the basis for Ciro's 2D reinforcement learning games, but ultimately decided it was a bit too messy. Nice overall though.

Also webpack and Babel, looks promising!
As of 2021, last commit from 2017.
Running:
git clone https://github.com/Codaisseur/feathersjs-react-redux-ssr
cd feathersjs-react-redux-ssr
npm install
failed on Ubuntu 20.10 Node.js v14.15.3 with:
../src/create_string.cpp:17:37: error: no matching function for call to ‘v8::String::Utf8Value::Utf8Value(v8::Local<v8::Value>&)’
   17 |   v8::String::Utf8Value string(value);
      |                                     ^
Likely similar bullshit from: stackoverflow.com/questions/50111688/node-sqlite-node-gyp-build-error-no-member-named-forceset-in-v8object because the Node.js version is too new.
If I try nvm install v10
I Google error messages until reaching:

Code drop Updated 2025-07-16
Open source development model in which developers develop in private, and only release code to the public during releases.
Notable example project: Android Open Source Project.
This development model basically makes reporting bugs and sending patches a waste of time, because many of them will already have been solved, which is why this development model is evil.

Codomain Updated 2025-07-16
Vs: image: the codomain is the set that the function might reach.
The image is the exact set that it actually reaches.
E.g. the function:
could have:
Note that the definition of the codomain is somewhat arbitrary, e.g. could as well technically have codomain:
even though it will obviously never reach any value in .
The exact image is in general therefore harder to characterize.

This dude is mind blowing. Big respect.
Some of the most impressive videos are the ones in which he goes and extracts metals from minerals himself all the way.
But God, the typography of the channel name is so insane! Why no space???
Shame the academic system wasn't compatible with him: www.reddit.com/r/codyslab/comments/f5531p/codys_qualifications/ Maybe there were safety issues involved though.

Coherence time Updated 2025-07-16
It takes time for the quantum state to evolve. So in order to have a deep quantum circuit, we need longer coherence times.
Coinbase Bitcoin hello world Updated 2025-07-16
Test buy 2023-04-10 in the UK:
  • fee: 0.99 pounds, minimum buy: 1.99 pounds
  • bought 10 pounds, minus 0.99 fee, totalled: 0.00039162 BTC (£8.92) presumably after further fees/spread
  • bitcoin price on Google on that day: 22,777.54 GBP / BTC
  • bitcoin transaction fees were about 2.7 BTC on that day
Sending 5 pounds to wallet 12dg2FaiZLp3VzDtLvwPinaKz41TQcEGbs
  • network fee: 0.00001989 BTC
  • total bitcoin cost: -0.00023928 BTC
  • new balance: 15,234 satoshi (39,162 - 23,928).
  • total spent: £5.45
  • time est.: about 30 minutes
This worked and I received 21939 satoshis (23928 - 1989) on Electrum on one of the outputs of transaction 1177268091cbeaacbcaac5dc4f6d1774c4ec11b4bcffafa555cd2775eafb954c.
Sending 1 satoshi back! The lowest fee in Electron is 1120 Satoshis targeting 25 blocks (4 hours). Let's do it. Failed, server forbids dust, minimum is 1000 satoshi. OK, sending 1000 satoshi, at 1139 fee.

CoinGeek is either run by or paid for by Craig Wright. You can see that all of the articles are either strongly in his favor or in line with his recent opinions.

Not a quantum computing pure-play, they also do sensing.
Published on Nature at www.nature.com/articles/122990a0 and therefore still paywalled there as of 2023, it's ridiculous.
In 2024 it will fall into the public domain in the US.
College of the University of Oxford Updated 2025-07-16
A good explanation of how this insane system came up is given at Video "History of Oxford University by Chris Day (2018)".
As if it weren't enough, there are also the 6 Halls: permanent private hall.
The colleges are controlled by its fellows, a small self-electing body of highly successful scholars, usually in the dozens per college number it seems. Each college also usually has different types of fellows, e.g. see he university college page: www.univ.ox.ac.uk/about/college-fellowships/ (archive)
The college system does has its merits though, as it instates a certain sense of Hogwarts "belonging" to a certain group, so it might help students get better support for their learning projects from older students, or through the tutoring system. Of course, all such "belonging" feelings are bad, the correct thing would be to make great online tutorials for all, and answer questions in the open. But oh well, humans are dumb.
The college you are in impacts the quality of your courses, because tutorials are per-college. As of 2023, Ciro Santilli spoke to some students of the Computer science course of the University of Oxford, and was told that in some cases where you don't have anyone who can give the tutorial, you instead get a "class", i.e. a P.h.D. student going through question sheets with no interaction in the C.S. department, rather than a deep interactive discussion over the college fire. How can this system be so broken, it is beyond belief
This functionality is somewhat related to fraternities and sororities in 2000's United States.
College puffer jacket Updated 2025-07-16
E.g.: thecollegestore.co.uk/products/ladies-oxford-college-puffer-jacket?variant=40590030864549 Black with 5 rows, on left chest "colege name", logo, "Oxford", and right chest optional initials (or sometimes other identifiers/nicknames) to help distinguish from all the other people's identical clothes.
This has a whitelabel version: www.workweargiant.co.uk/product/result-urban-holkham-down-feel-jacket/, the name appears to be "Holkham Down Feel Jacket".
Circa 2020, these are likely given out by each college for free, and are widely used.
If you look 20 and wear one of those, it's almost an ID, you can get anywhere that does not require a key card, porters won't look at you twice!
