Extra Tips:

• clean up upfront!
• simple is the new clever!

git house-keeping:

git remote prune origin (removes all stale remote branches)

sind ja alles meine Argumente... aber niemand möchte damit anfangen, den Code aufzuräumen... sehr schade eigentlich, gerade wird Strategie gefahren - lieber mehr Hardware, als performantere App... aber ich geb noch nicht auf, vllt. kann ich doch noch was bewegen.

Cheers und danke für die Unterstützung! Grüße nach USA!

Kannst ja langsam die nicht 1.9 sachen killen wenn du ihnen begegnest (z.B. mit 1.9 entwickeln), dann ists irgendwann einfacher :)
