Wind in the pines and a babbling brook are nature's melody. A qin was brought along, but there is no need to play it
The The Gateless Barrier vibe and Chinese naturalism is just awesome.

Bilinear map Updated +Created
Linear map of two variables.
More formally, given 3 vector spaces X, Y, Z over a single field, a bilinear map is a function from:
that is linear on the first two arguments from X and Y, i.e.:
Note that the definition only makes sense if all three vector spaces are over the same field, because linearity can mix up each of them.
The most important example by far is the dot product from , which is more specifically also a symmetric bilinear form.
Dwarf Fortress Updated +Created
Made by a single dude. As SsethTzeentach puts it, this is the greatest autism project ever made.
Limited series Updated +Created
If you are going to make a television series, do make it a limited one. Plan one story, and execute it amazingly. Don't let things drag on and on.
Matrix representation of a linear form Updated +Created
For the typical case of a linear form over , the form can be seen just as a row vector with n elements, the full form being specified by the value of each of the basis vectors.
Punycode inscription Updated +Created
Namecoin examples are catalogued at: punycodes.xyz. The are small Unicode art or emoji code.
There seems to be nothing of particular artistic value as far as we've seen so far, the only interest in such tokens seems to be that:
Relativistic quantum mechanics Updated +Created
The first really good quantum mechanics theory made compatible with special relativity was the Dirac equation.
TODO: does it use full blown QED, or just something intermediate?

Analects translation by Robert Eno (2015) 16.7:
The Junzi has three cautions.
When he is young and his blood and energy are not yet settled, he is cautious about sex.
When he is in his prime and his blood and energy have newly achieved strength, he is cautious about combativeness.
When he is old and his blood and energy are declining, he is cautious about acquisitiveness.
Algebraic structure Updated +Created
A set plus any number of functions , such that each satisfies some properties of choice.
Key examples:
  • group: one function
  • field: two functions
  • ring: also two functions, but with less restrictive properties

More important than the monk itself in Chinese culture, it is used as a Budhist Amen. TODO find some usage in some Chinese television series.

www.gvgai.net (dead as of 2023)
The project kind of died circa 2020 it seems, a shame. Likely they funding ran out. The domain is dead as of 2023, last archive from 2022: web.archive.org/web/20220331022932/http://gvgai.net/. Marks as funded by DeepMind. Researchers really should use university/GitHub domain names!
Similar goals to Ciro's 2D reinforcement learning games, but they were focusing mostly on discrete games.
They have some source at: github.com/GAIGResearch/GVGAI TODO review
Hacker News Updated +Created
The most popular programming news sharing forum of the 2010's by far. If your content gets shared there, and it stays on top for a day, the traffic peak will be incredible. Reddit posts are sure to follow.
Basically a programming-only Reddit-lite.
Ciro Santilli had a few of his content shared there as mentioned at the best articles by Ciro Articles.
Hamilton's equations Updated +Created
Analogous to what the Euler-Lagrange equation is to Lagrangian mechanics, Hamilton's equations give the equations of motion from a given input Hamiltonian:
So once you have the Hamiltonian, you can write down this system of partial differential equations which can then be numerically solved.

The Fall of The Simpsons: How it Happened by Super Eyepatch Wolf (2017)
Source. This interesting video essay makes the main point that the Simpsons used to be good because they mocked mainstream. But then they became mainstream, which basically defeated their purpose. Think different from Apple comes to mind.
