Because these billboards are just monitors rotated 90 degrees, they’re invisible to polarized sunglasses. It’s like a real-life ad blocker!

The billboard blocked by sunglasses.

@jon is there a complete set of rules / exceptions what is allowed with Deutschlandticket? Maybe even machine readable so it can be easier implemented in routing engines?

gerdcastan,

@Einzigartiger @jon that answer comes near what I am searching for.
I am aware that DB navigator and others don't implement this. But it could be implemented in open source routing engines, if the data was available.

gerdcastan,

@Einzigartiger @jon so I learned from that map, that this IC has a double train number RE87, which is actually found by bahn.de and others 😃

Why are so many American pedestrians being killed by car-drivers at night?

Fascinating piece in the New York Times (free link here: https://www.nytimes.com/interactive/2023/12/11/upshot/nighttime-deaths.html?unlocked_article_code=1.FE0.uEMf.FuV3jZhYzZHu&hpgrp=k-abar&smid=url-share) on this question

After years of decline, the number of pedestrians killed by drivers began to rise in 2008 -- but only at night

No-one's quite sure why

Embiggified vehicles don't seem to be the cause ...

... though distracted driving does seem to be part of it

Also: more people living alongside massive highway-esque suburban roads

gerdcastan,

@clive USA has no laws that mandate building cars in a way that protects pedestrians

Fraunhofer: Natrium-Ionen-Technik eine nachhaltige Batterie-Alternative

Die wachsende Lithium-Ionen-Technik erzeugt Rohstoffprobleme. Natrium-Ionen-Batterien bieten geringere Energiedichte, aber die Ressourcen sind gut verfügbar.

@heiseonline ich halte die künftig besonders zuhause als Ergänzung zur Photovoltaik für interessant:

  • billig, wenn es in Massen produziert wird
  • 30% höheres Volumen pro kWh macht nichts
  • wenig feuergefährlich
  • hoher Temperaturbereich, auch wenn‘s sehr kalt ist

The world is going mad.

Just been to a DM in München to buy Corona tests. “We don’t have any” was the rather worrying response. “Will you ever get some in stock?” “We don’t know”

Is this really right?

Corona hasn’t gone away!

EDIT: asked at another DM. SOLD OUT. No idea when any new will come in.

Went to a pharmacy - got the last 2 tests they had in stock 😢

gerdcastan,

@jon big A sells them so dirt cheap that no store can compete.

Some of the best, Hotgen, cost 22ct / ea

I think I‘ll buy again 39 and give away most of them again.

OK, wenn etwas kompliziert ist... braucht es ein Diagramm!

Woher weisst man, wo das Deutschlandticket gültig ist?
