# Xcode to Map Vim Keys

There is no built-in way to add custom key mappings in Xcode 13’s Vim Mode.

This is a workaround.

It depends on karabiner-elements.

Java / elasticsearch

First, remove all existing java installations:

sudo apt-get purge openjdk-\*
sudo rm -rf /usr/lib/jvm/*

Install Java 8, same version as on build server:

In Termux:

pkg update
''' Pythonic means "coding beautifully in harmony with
the language to get the maximum benefits from Python"
Learn to recognize non-pythonic APIs and to recognize
good code. Don't get distracted by PEP 8. Focus
first an Pythonic versus NonPython (P vs NP).
When needed, write an adapter class to convert from
the former to the latter.
* Avoid unnecessart packageing in favor of
simpler imports

with NetworkElement('') as ne:
for route in ne.routing_table:
print "%15s -> %s" % (, route.ipaddr)
ne ='')
routing_table = ne.getRoutingTable()
