Since the #xz incident started, I've been maintaining an FAQ/living document on what we know at https://gist.github.com/thesamesam/223949d5a074ebc3dce9ee78baad9e27.

I think most people in my extended circle either already seen it but posting about it given there's likely to be a lot more questions as we go into the working week.

Thank you to everyone who has contributed tips, suggestions, and edits. Thanks especially to @cadey who has helped a lot with editing.

Cistercian Numbers; are an extremely interesting and basically forgotten number system developed 8 Centuries Ago. It is much more compact than Arabic and Roman systems, you can basically write any integer from 1 to 9999 with one character.

Gestern haben wir den Anteil des Luftwiderstands am Stromverbrauch von E-Autos bestimmt [1]. Heute kommt der Rollwiderstand dran.

Den Anteil des Rollwiderstandes am Stromverbrauch (in kWh/100km) auf gerader Strecke ergibt sich, wenn man

0.0035425 * M

in den Taschenrechner eingibt, wobei M die Gesamtmasse des Fahrzeuges ist; die bekommt man z.B. von hier: [2].

Herleitung in Teil 4 und 5.
