To restore the save, just close the game window directly before clicking Yes or No on the "Watch the last moments of your life" dialog.

A less risky save scum can be achieved with rsync:

rsync -av ~/.local/share/cataclysm-dda/save/ ~/.local/share/cataclysm-dda/save.bak/

and after you die:

rsync -av ~/.local/share/cataclysm-dda/save.bak/ ~/.local/share/cataclysm-dda/save/

Some analysts seem to suggest that the things she said were bad.

But they're not.

They're a rare example of someone with some power saying cool honest stuff that comes across their mind.

Unlike the endless mandatory corporate bullshit we usually get otherwise.

Can't get you out of my head by Adam Curtis (2021) Updated 2025-07-16

Ciro Santilli was touched by this, and then watched several other documentaries by Curtis.

Part of Ciro asks if it is all a big conspiracy theory. But it feels and sounds so right.

Notably the part of the governments have lost all power to companies, and can't do anything meaningful anymore to actually represent the people, because globalization reduces the power of governments.

Contains the University of Cambridge, that's about it really, from that everything follows.

The city appear to exist there because it was a convenient crossing of the Cam. It also lies near the start of the ancient navigable section TODO towards north or south? Castle hill also offered a convenient fortification location near the river, and is part of the reason for the early Roman settlement. The original bridge was presumably in the current Magnalene bridge, just under the castle hill.

TODO why did the University of Oxford scholars flee to after the The hanging of the clerks in 1209? Why not anywhere else?

Ciro Santilli defines a "business film" as a film about business, enterprises or entrepreneurship. Political thrillers are closed related as well.

Quantum number Updated 2025-07-16

 View more

Quantum numbers appear directly in the Schrödinger equation solution for the hydrogen atom.

However, it very cool that they are actually discovered before the Schrödinger equation, and are present in the Bohr model (principal quantum number) and the Bohr-Sommerfeld model (azimuthal quantum number and magnetic quantum number) of the atom. This must be because they observed direct effects of those numbers in some experiments. TODO which experiments.

E.g. The Quantum Story by Jim Baggott (2011) page 34 mentions:

As the various lines in the spectrum were identified with different quantum jumps between different orbits, it was soon discovered that not all the possible jumps were appearing. Some lines were missing. For some reason certain jumps were forbidden. An elaborate scheme of ‘selection rules’ was established by Bohr and Sommerfeld to account for those jumps that were allowed and those that were forbidden.

This refers to forbidden mechanism. TODO concrete example, ideally the first one to be noticed. How can you notice this if the energy depends only on the principal quantum number?
