A bitcoin logo on block 123573 (2011-05-13).
This is the very first ASCII string to show up at github.com/cirosantilli/bitcoin-inscription-indexer after only the Genesis block message.
This version of the image was just ripped from Hidden surprises in the Bitcoin blockchain by Ken Shirriff (2014).
Reconstructing it should likely be a simple matter of copy pasting the ASCII yEnc encoding present in the two transactions from tx ceb1a7fb57ef8b75ac59b56dd859d5cb3ab5c31168aa55eb3819cd5ddbd3d806 into a text file and decoding the yEnc, but after searching for 20 minutes Ciro couldn't find a working yEnc decoder on Ubuntu 21.10. How can a format be so dead, even after considerable extensive use in the Usenet??? It makes you think about life.
As mentioned by Ken, the logo is split across two transactions: ceb1a7fb57ef8b75ac59b56dd859d5cb3ab5c31168aa55eb3819cd5ddbd3d806 and 9173744691ac25f3cd94f35d4fc0e0a2b9d1ab17b4fe562acc07660552f95518.
There appears to be nothing strictly linking the two transactions, besides that they are very close by and the only ASCII strings around back in those pre-infinite-spam days, as can be seen at: github.com/cirosantilli/bitcoin-inscription-indexer/blob/master/data/out/0123.txt#L11, so you could just see both of them by eye.
Also the first one starts with:
=ybegin line=128 size=8776 name=bitcoin.jpg
and the second one ends in:
=yend size=8776 crc32=a7ac8449
so this is likely clearly part of the yEnc format for someone who knows it, and the filename bitcoin.jpg gives the file format.
They are not even in the same block:both from 2011-05-13. Also note that they ended up being committed reverse order, since you don't have a strict order control over the final blockchain.

An image of a dozen people siting at a dinner table, with each person identified by a Twitter handle that was edited in.
This image is present tx 4be3a833ee83b4ca7d157d60fbf7411f7528314ce90df8a844f855118bc6ca11 from block 357239 (2015-05-20), an input transaction.
It contains a base 64 encoded image:
v27sSra.jpg

...
TAkBaMxbbhuYXGDMyXw/MIV84IqrE//Z
...
By manually copy pasting that into a file v27sSra.base64 we can obtain the image with:
base64 -d <v27sSra.base64 >v27sSra.jpg
The exact same content appears to be present on the next input transaction 56d23a230042c094bc54bb72fc4c10a3f26750030b9927994e741d3689f5c09e on the same block.
Google reverse image search leads to freedom-to-tinker.com/2015/05/21/the-story-behind-the-picture-of-nick-szabo-with-other-bitcoin-researchers-and-developers/ The story behind the picture of Nick Szabo with other Bitcoin researchers and developers by Arvind Narayanan (2015), in which Arvind (@random_walker) who attended the meeting clearly lists all names and handles, and talks about the background of gathering of Bitcoin devs that happened in March 2014. The article also contains a higher resolution version of the image uploaded to the blockchain.
It also links to a popular Reddit thread that contains the image from May 2015: www.reddit.com/r/Bitcoin/comments/36hfu4/pic_coredevs_having_dinner_with_nick_szabo/
Googling v27sSra.jpg leads to bitcointalk.org/index.php?topic=1061926.220;wap "New York Times identifies Nick Szabo as Satoshi Nakamoto" which links to i.imgur.com/v27sSra.jpg so this is a Satoshi Nakamoto-real-identity thing.

The transaction before the ASCII art tx 9b08c00ced2bca4525d74e82db9af2aec8ef213eb1c1bf68a48b6be929968332 starts with what is likely a "Legalize" and must be a Tor Onion service:

but that address as is + .onion is invalid, TODO find the correct one.
Other marijuana plants can be found contained entirely in single transactions:

Amazon custom silicon by Ciro Santilli 35 Updated +Created
Like Google custom silicon, Amazon server operations are so large that with the slowdown of Moore's law, it started being worth it for them to develop custom in-house silicon to serve as a competitive advantage, not to be sold for external companies. Can you imagine the scale required to justify silicon development investment that is not sold externally!

x86 Paging Tutorial by Ciro Santilli 35 Updated +Created
This tutorial explains the very basics of how paging works, with focus on x86, although most high level concepts will also apply to other instruction set architectures, e.g. ARM.
The goals are to:
  • demonstrate minimal concrete simplified paging examples that will be useful to those learning paging for the first time
  • explain the motivation behind paging
This tutorial was extracted and expanded from this Stack Overflow answer.
Parity violation by Ciro Santilli 35 Updated +Created
This is quite mind blowing. The laws of physics actually differentiate between particles and antiparticles moving in opposite directions!!!
Only the weak interaction however does it of the fundamental interactions.

It gets worse of course with cP Violation.
