Paris Updated +Created
Ciro Santilli lived in Paris for a few years between 2013 and 2016, and he can confirm the uncontroversial fact that "Paris is Magic".
Not just one type of magic though. Every quarter in Paris has its own unique personality that sets it apart and gives it a different mood.
Ciro knows Paris not from its historical facts, but from the raw feeling of endless walks through its streets in different times of the year. Ciro is a walker.
Maybe one day Ciro will expand this section to try and convey into words his feelings of love for the city, but maybe the effort would be pointless. Maybe such feelings can only be felt by other free-roaming walker souls living in the city, and that is both beautiful and a shame.
Ciro had written the following in the past before he lived in smaller cities, started cycling and joined the Street reclamation movement he thought:
Paris is a friendly city to walkers, as it is not too large, and does not have too many extremely busy roads, you can basically cross all of it on foot.
Perhaps compared to São Paulo City, which is what he knew before that was true. But no, his standards have improved since. Paris has way too many cars. The noise of internal combustion engine vehicles is extremely annoying. And because there are too many personal vehicles, cars have to horn a lot to fight for space. Fuck cars. Paris has been making a big cycling push in the early 2020's, and that is great. But it is still far, far from good.

Cancer is natural selection gone wrong Updated +Created
A cool thought about cancer expressed at Power, Sex, Suicide by Nick Lane (2006) is that cancer it is the direct product of natural selection gone wrong!
Cancer cells are obviously selected against anti-cancer mechanism, which when they manage to evade, they reproduce uncontrollably, gaining more and more momentum.
Cardinality of the continuum Updated +Created
Calibre (software) Updated +Created
Sometimes Ciro Santilli says half jokingly that user interface does not matter.
This software circa 2010-2020 makes that joke not be funny.
How can a UI feel so clunky!
The most aggravating thing is that it is not immediately obvious why it feels so bad.

Whenever someone asks:
I can only see this one thing different our setups, do you think it could be the cause of our different behaviour?
you don't need to read anymore, just point them to this page immediately. Virtualization for the win.

It is quite amusing that the starting point to identifying the heat one was capsaicin, as it stimulates the exact same receptor!!!

PNG reference implementation. Ahh, if feels good to have a dominating open source reference implementation.

Causality and quantum jumps are incompatible Updated +Created
If something does a quantum jump, what causes it to decide doing so at a particular time and not another? It is expected that a continuous cause would have continuous effects.
This concern was raised immediately by Rutherford while reviewing the Bohr model in 1913 as mentioned in The Quantum Story by Jim Baggott (2011) page 32.
