Git serve: I would like it that simple
...lowing switches:
cd project
git daemon --reuseaddr --base-path=. --export-all --verbose
This tells git-daemon to serve up all projects inside the current directory (which I assume is the project directory containing the .git/ folder). It also tells it to re-use the same address if you shut it dow...
Difference between malloc and calloc?

...arting from wherever you are
now. Now you can commit and the new stuff is all on develop.
You do have a develop. See if Git will let you switch without
doing anything:
$ git checkout develop
This will either succeed, or complain. If it succeeds, great! Just

Which terminal command to get just IP address and nothing else?
...
This will give you all IPv4 interfaces, including the loopback 127.0.0.1:
ip -4 addr | grep -oP '(?<=inet\s)\d+(\.\d+){3}'

Is it possible for intellij to organize imports the same way as in Eclipse?
I'm working on a project where all the team members are using Eclipse and I'm the only IDEA user. This creates a lot of noise from imports rearrangements. The order in which eclipse imports is: Java, Javax, Org, Com, everything else in alphabetical order. Is it possible to configure IDEA to follow t...
javax vs java package
...rlier versions (which would be useful). Note from many years later: it actually ended up being in java after all.
