A conjecture is an open problem in mathematics for which some famous dude gave heuristic arguments which indicate if the theorem is true or false.
For positive definite matrices only.
TODO application.
www.studentclustercompetition.us/ comments:
The HPCG benchmark uses a preconditioned conjugate gradient (PCG) algorithm to measure the performance of HPC platforms with respect to frequently observed but challenging patterns of computing, communication, and memory access. While HPL provides an optimistic performance target for applications, HPCG can be considered as a lower bound on performance. Many of the top 500 supercomputers also provide their HPCG performance as a reference.
A Drosophila melanogaster has about 135k neurons, and we only managed to reconstruct its connectome in 2023.
The human brain has 86 billion neurons, about 1 million times more. Therefore, it is obvious that we are very very far away from a full connectome.
Instead however, we could look at larger scales of connectome, and then try from that to extract modules, and then reverse engineer things module by module.
This is likely how we are going to "understand how the human brain works".
Some notable connectomes:
- 2019: 1mm cube of mouse brain: www.nature.com/articles/d41586-019-02208-0
- 2023: Drosophila connectome
China stuff is mentioned at: cirosantilli.com/china-dictatorship/bitcoin-blockchain.
royalsociety.org/grants-schemes-awards/awards/copley-medal/ says it is now open to international citizens, but having a quick look at the 2010 awards still suggests that it is very British centric, or at least anglophone centric, much like the society fellowship itself. That's likely the reason why the Nobel prize won, being much more international from the start.

An "artificially" colored visualization of the Arecibo message ripped from Wikipedia: en.wikipedia.org/wiki/File:Arecibo_message.svg (with attribution).
The cool thing about this image is that it highlights the striking parallels between the encoding of the Arecibo message with crypto graffiti, because in both cases people were creating undocumented new ways of communicating with strangers on a new medium in those early blockchain days.
The associated message contains the Arecibo message as ASCII 0's and 1's. When properly cut at the newlines, they draw the message as ASCII art, as the original Arecibo encoding intends, here's a version with the 0's replaced by spaces to make it more readabale:

The image is present e.g. at: www.kitguru.net/channel/jon-martindale/australian-man-claims-he-is-satoshi-nakamoto-bitcoin-creator/ It was inscribed about two months after Craig publicly claimed that he is Satoshi.
This is a relatively unusual AtomSea & EMBII upload as it does not have the common toplevel transaction, everything, text + image fits into a single transaction. This is perhaps why the image is relatively low resolution to have a smaller size.

At twitter.com/EMBII4U/status/1615389973343268871 EMBII announced that he would be giving off shares of that image on a Bitcoin-based NFT sale system he's making called Sup!?, and in December 2023 gave 2/300 shares to Ciro Santilli. Amen. The transaction list can be seen on the web UI at: p2fk.io/GetObjectByAddress/1KUyhHLrK1ckY8W7Qu31h6gFkXoihWHMzi?mainnet=true&verbose=true It had unfortunately never sold as of 2025, the only activity was EMBII giving off some shares and two listings of 1/300 for 1 BTC.

TODO purpose? The transcripts are interspersed with developers likely voting for project leadership, and commenting on Gavin.
TODO find original discussion location, these are almost certainly from one of the Bitcoin IRC channels.
Part of the goal of this dump is that the Bitcoin developers have a policy of not allowing logging on their talk channel, and this released it all to the blockchain forever where it cannot be deleted. These might just be more of protests against larger block sizes.
