> The travel time between, e.g., Berlin and Paris is something like four to five times as long as by plane.
I think your estimate is quite off here: Train connections from Berlin to Paris take about 8.5 hours. Flights take 1 hour and 50 minutes plus the overhead time for traveling to and from the airport, security and taxiing. Just let's suppose that this will be 2.5 hours in total, which would be very fast. So we are comparing 8.5 hours with 4.5 hours. So, the factor is less than two rather than the four to five you suggested.
I can only speak for the use in the German language:
The German language allows you to compose several words into one long word, which is no longer structured by spaces. This can lead to ambiguities, especially where a sub-word ends with an S. Due to the rule that words always end with a round S, these ambiguities were resolved.
Yes, the train rides were in the night programme of ARD during the 90s [1]. Meanwhile, the other public German TV channel ZDF did the contrast program with a different mode of transportation: They had dash cam views of car rides [2].
Elasticsearch is actually using SecurityManager with quite thoroughly locked down policies; and it seems that this actually saved ES from being vulnerable to the RCE.
The irony is now that OpenJDK just recently decided to deprecate the SecurityManager in Java 17 and remove it in Java 18.
The official commemoration ceremony with all German top politicians took place at Bernauer Straße. That was probably the reason why the street was blocked by police.
The border between West and East Germany was already heavily fortified in 1952. So, during the nine years until 1961, West Berlin was indeed a kind of porthole to the west.
The reasons why the East German government did not close the border within Berlin are complex. For example the Sowjets first had the goal to make Berlin an independent but unified city. But there were also economical and logistical issues: The border would cut important railway transport routes for East Berlin, for which a replacement was only completed in 1961.
