There’s no need for a full-blown RDBMS for a simple blog

Right - I guess I would expect "No SQL" or "No database", rather than the specific call-out of Postgres.

The snippets actually do the same thing, as long as you add a .findFirst() to the first example to make it valid Java code.

Intermediate stream operations like map or filter are always lazy. And .findFirst() is a short-circuiting terminal operation, that does not need to consume all stream elements.

obviously that was the point, if you don't even care to write correct code, you can make every piece of code look bad.

Truth is java streams and, even more, reactive java are the only two things that make java bearable, god save who invented them.

If I had to program java with for loops and list.add or null checks everywhere, I would probably kill myself on the spot.

But the amount of programmers taught to program like it's still 1995 it's so damn high

And I am closer to my 50s than my 40s, I can't understand why people fresh from uni say they can't understand something like

  list.stream() 
  .map(this::maybeGetUser)
  .filter(maybeUser -> userIsPresentAndNameStartsWith(maybeUser, prefix))
  .findFirst()
  .orElseThrow(new UserNotFoundException());

with the benefit of being lazy and only inspecting list items up to the first one that matches (and if you don't mutate any data, easily parallelizable)

Not always I guess. The 20.04 and 20.10 installer with LUKS enabled created a swap partition for me.

And with Locus maps you can use OpenAndroMaps [1] as a map source.

With their map styles [2] OpenAndroMaps are IMO the best hiking maps you can get. They even added very precise elevation data from LIDAR scans recently.

Locus also have a store where they sell offline maps very similar to OpenAndroMaps for very small amounts. Not sure if they include elevation data however.
