LLVM Intermediate Representation Updated +Created
Very hot stuff! It's like ISA-portable assembly, but with types! In particular it also it deals with calling conventions for us (since it is ISA-portable). TODO: isn't that exactly what C does? :-) LLVM IR vs C
Get Bitcoin transaction id from position in dat file Updated +Created
Suppose we specify:
  • a .dat file
  • the offset in bytes within that file
The question then is, which transaction is encoded at that position of the file?
This would allow us to index inscriptions in the .dat files directly with fast C tools, and then retrive the transaction ID to get cleaner data and metadata.
It should be possible if we managed to take the information from bitcoindev.network/understanding-the-data/ and dump into an indexed SQLite database.
I tried to start things off with LevelDBDumper:
LevelDBDumper -d ~/snap/bitcoin-core/common/.bitcoin/indexes/txindex -f btc.csv -q -o . -t csv
but that consumed all 64 GB of RAM on P51... github.com/mdawsonuk/LevelDBDumper/issues/15
But OK, nevermind that repo, it can be done easily with the LevelDB API of any language: bitcoin.stackexchange.com/questions/121888/what-is-the-data-format-layout-for-txindex-leveldb-values. Just the data seems wrong and we don't know why.

One strange quark bound with one up quark or a down quark. 6 combinations exist, 4 if we consider antiparticles the same as particles.

The Biggest Ideas in the Universe | 11. Renormalization by Sean Carroll (2020)
Source. Gives a very quick and high level overview of renormalization. It is not enough to satisfy Ciro Santilli as usual for other Sean Carroll videos, but it goes some way.

Josephson voltage standard Updated +Created
The most practical/precise volt standard.
The wiki page en.wikipedia.org/wiki/Josephson_voltage_standard contains amazing schematics of the device, apparently made by the US Government.

Gauge theory Updated +Created
The term and idea was first introduced initialized by Hermann Weyl when he was working on combining electromagnetism and general relativity to formulate Maxwell's equations in curved spacetime in 1918 and published as Gravity and electricity by Hermann Weyl (1918). Based on perception that symmetry implies charge conservation. The same idea was later adapted for quantum electrodynamics, a context in which is has even more impact.
Heisenberg picture Updated +Created
Basically the same as matrix mechanics it seems, just a bit more generalized.

This is good software.
If it only it were written in JavaScript instead of Haskell (!?), then Ciro might have used it as the basis for OurBigBook Markup.

Journals must require source code and data sets to publish Updated +Created
It is understandable that you might not be able to reproduce a paper that does a natural science experiment, given that physics is brutal.
But for papers that have either source code or data sets, academic journals must require that those be made available, or refuse to publish.
Jump wire Updated +Created
Notably used to connect:
You can buy large sets of them in combitation of male/male, male/female, female/female. Male/male is perhaps the most important
