Ciro Duran Santilli Updated 2025-07-16
View more
Ciro Santilli's full birth name is "Ciro Duran Santilli", with mother's last name "Duran" in the middle as per Brazilian tradition.
But Ciro's usage of "Duran" got gradually dropped to "Ciro Santilli", Ciro's official Italian name, as Ciro moved more and more definitively to Europe.
It can still however be seen in certain online places where Ciro didn't have the patience or power to change it e.g. some old École Polytechnique stuff: gitlab.binets.fr/ciro.duran-santilli/china-dictatorship
Also, don't have multiple names if you can avoid it, it is confusing!

Facebook's original niche was college, and that was cool. Then it became this more diluted and irrelevant thing. If only they had added knowledge sharing to it, OurBigBook would have been done then and there.

Cool data embedded in the Bitcoin blockchain / Cursed ordinal Updated 2025-07-16
View more
These were ordinals that were only indexed in later versions of the script. So to prevent changing the useless indices of existing ordinals, they gave them negative numbers.
The word "cursed" is a meme from the 2010/20s, e.g. knowyourmeme.com/memes/cursed-images--2.
Some examples:

Sample usage:
sudo tshark -f 'host 192.168.1.102
This produces simple one liners for each request.
What you likely want is the -V option which fully disassembles each frame much as you can do in the GUI Wireshark:
sudo tshark -V -f 'host 192.168.1.102

Official Bitcoin domain registered by Satoshi Nakamoto.
Registration: 2008-08-18 by www.namecheap.com, an American company. But using a privacy oriented registrar: bitcoin.stackexchange.com/questions/89532/how-did-nakamoto-untraceably-pay-for-registering-bitcoin-org It is unknown how he could have paid anonymously, so it seems likely that the true identity could be obtained by law enforcement if needed.

FFmpeg filter graph Updated 2025-07-16
View more
Filter graphs are a thing of great beauty. What an amazingly obscure domain-specific language, but which can produce striking results with very little!!!
ffplay -autoexit -nodisp -f lavfi -i '
sine=frequency=500[a];
sine=frequency=1000[b];
[a][b]amerge, atrim=end=2
'
which creates a graph:
                              +--------+
[sine=frequency=500]--->[a]-->|        |
                              | amerge |-->[atrim]-->[output]
[sine=frequency=1000]-->[b]-->|        |
                              +--------+
and plays 500 Hz on the left channel and 1000 Hz on the right channel for 2 seconds.
So we see the following syntax patterns:
  • sine, amerge and atrim are filters
  • sine=frequency=500: the first = says "araguments follow"
    • frequency=500 sets the frequency argument of the sine filter
    • for multiple arguments the syntax is to separate arguments with colons e.g. sine=frequency=500:duration=2
  • ;: separates statements
  • [a], [b]: sets the name of an edge
  • ,: creates unnamed edge between filters that have one input and one output
A list of all filters can be obtained ith:
ffmpeg -filters
and parameters for a single filter can be obtained with:
ffmpeg --help filter=sine

Awesome tool to view quick stuff quickly without generating files. Unfortunately it doesn't support all options that the ffmpeg CLI supports, e.g. ffplay multiple input files. One day, one day.
