As if Chinese character weren't evil enough, their fast hand written form is even more unintelligible. It is like Hell within Hell.
It is also very beautiful it must be said.

Ciro Santilli's joke version of the Chinese Four Treasures of the Study!
  • web browser
  • Text editor
  • terminal. Though to be honest, circa 2022, Ciro learned of the ctrl + click to open file (including with file.c:123 line syntax) ability of Visual Studio Code (likely present in other IDEs), and he was starting considering dumping the terminal altogether if some implementation gets it really really right. The main thing is that it can't be a tinny little bar at the bottom, it has to be full window and super easily toggleable!
In the past, Ciro used to use file managers, which would be the fourth tresure. But he stopped doing so for years due to his cd alias... so it became three. He actually had exactly three windows open when he was checking if there was anything else he could not open hand of.

. Featuring: Gvim, tmux running in GNOME terminal, and Chromium browser on Ubuntu 22.04. The minimized windows are for demonstration purposes, Cirism mandates that all windows shall be maximized at all times. Splits withing a single program are permitted however.
Bitcoin halvening Updated +Created
cointelegraph.com/learn/bitcoin-halving-how-does-the-halving-cycle-work-and-why-does-it-matter Happens every 210,000 blocks, aiming approximately at 4 year intervals. The historical dates were:
  • 50 BTC initially
  • 1st: 2012: down to 25 BTC
  • 2nd: 2016: down to 12.5 BTC
  • 3rd: 2020: down to 6.25 BTC
Each of these events prompts some commemorative inscriptions: Section "Halvening messages".

BLAST (biotechnology) Updated +Created
BLAST is a sequence alignment.
The NCBI free-to-use BLAST server: blast.ncbi.nlm.nih.gov/Blast.cgi. Having a centralized query server is fundamental, because the gain of sequence alignment really comes from having one huge database to link information together, which is best centralized.

Coinbase message are messages that only miners can embed in the blockchain.
As such most of them tend to be boring ads for mining pools, but there are a few exceptions, especially in the early days.

We looking at the definition the orthogonal group is the group of all matrices that preserve the dot product, we notice that the dot product is one example of positive definite symmetric bilinear form, which in turn can also be represented by a matrix as shown at: Section "Matrix representation of a symmetric bilinear form".
By looking at this more general point of view, we could ask ourselves what happens to the group if instead of the dot product we took a more general bilinear form, e.g.:
The answers to those questions are given by the Sylvester's law of inertia at Section "All indefinite orthogonal groups of matrices of equal metric signature are isomorphic".

A more concrete and easier to understand version of it is the more photon-specific Poincaré sphere, have a look at that one first.
