Connectome scale Updated 2025-07-11 +Created 1970-01-01
View more
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".

Copley Medal Updated 2025-07-11 +Created 1970-01-01
View more
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.

For my first official Journal entry I've decided to archive some old poetry. Here are a few of the computational poems I've created using cyphers.

"Even if we tried to do it on purpose, never would have we succeeded." My beloved Vincent.

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 shop on the right corner has a sign that starts with "Bo" and searching for "Auckland Bo" gave us the "The body shop" on the corner of Queen Street and Darby Street. Some things changed between 2015 and 2024, notably the bench is gone and the shop on the left corner changed, but we can go back in time in Google Street View to 2015 which further confirms the location.

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.

The associated message reads:
Chiharu and I found this little yellow robot while exploring Chicago. It will be covered by tar or eventually removed but this tribute will remain. N 41.880778 E -87.629210
This is one of Ciro's favorite AtomSea & EMBII uploads. This is the cutest thing ever, and perfectly encapsules the "medium as an artform" approach to blockchain art. More Chiharu stalking at: ILoveYouMore.jpg.
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. Poor EMBII!

jgarzik: if you aren't near one of the consulates there are some companies that will charge you money to do it...
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.

Some courses at least allow you to see material for free, e.g.: www.coursera.org/learn/quantum-optics-single-photon/lecture/UYjLu/1-1-canonical-quantization. Lots of video focus as usual for MOOCs.
It is extremely hard to find the course materials without enrolling, even if enrolling for free! By trying to make money, they make their website shit.
The comment section does have a lot of activity: www.coursera.org/learn/statistical-mechanics/discussions/weeks/2! Nice. And works like a proper issue tracker. But it is also very hidden.
