Cool data embedded in the Bitcoin blockchain Largest ordinal inscription Updated 2025-07-16
We can get a list of the ordinals at: archive.org/details/bitcoin-ordinal-inscriptions.csv and then sort them by payload size with:
sort -k6 -n -t, ordinals.csv -o ordinals-sort-size.csvThis shows to us that as of block ~831k, there are 4 ordinals which are far far larger than any other between 3 MiB and 4 MiB, at about 10x larger than then 5th one d115a6e689086fd587e5032f24ba2a8c01f2f87cba758c9d5eb8cf7f6e9a816a
In those cases, a single inscription takes almost the entire block, and the inscribers must have had direct dealings with their mining pool:

Particular attributes the ideal Chinese scholar would have include:It is in a sense sad (or awesome) that the computer has essentially replaced, or one may argue, enhanced beyong recognition, all of the traditional four arts, to the point that Ciro can't touch anything that is not a computer. Sometimes the old arts live on particularly closely though, e.g. in computer music, computer graphics and computer Go.
- mastery of the Four arts, which also implies the Four Treasures of the Study for caligraphy and painting

One is reminded of Nick Leeson.
One things must be said: the root cause of all of this is the replication crisis.
This is why he managed to go on for so long.

As for his lost password and inaccessible Bitcoin, Mr. Thomas has put the IronKey in a secure facility - he won’t say where - in case cryptographers come up with new ways of cracking complex passwords. Keeping it far away helps him try not to think about it, he said.
“I would just lay in bed and think about it," Mr. Thomas said.
ffplay multiple input files Updated 2025-07-16
TODO possible? superuser.com/questions/559768/ffplay-how-to-play-together-separate-video-and-audio-files
For synthesized streams like but it does not seem to accept multiple fails with:
sine we can do it e.g.ffplay -autoexit -nodisp -f lavfi -i '
sine=frequency=500[a];
sine=frequency=1000[b];
[a][b]amerge, atrim=end=2
'-i for some reason. So is there a way to open a file from some filter? E.g.:ffplay -i tmp.wav -i tmp.mkv -filter_complex "[0:a]atrim=end=2[a];[1:v]trim=end=2[v]" -map '[a]' -map '[v]'Argument 'tmp.mkv' provided as input filename, but 'tmp.wav' was already specified.
