JAVA_HOME on OS X

I just stumbled upon setting the JAVA_HOME on a remote OS X Server. I tried following the output of whereis. But this was not leading me to the right track folders.

To make things short, just add this to your .profile/shell:

export JAVA_HOME=$(/usr/libexec/java_home)

bowery.io – limitless development environment

Bowery is a limitless development environment available at http://bowery.io/.It is free for DEVELOPERS and STARTUPS. All you need to do is configure one simple file per host. With a few lines bowery is setting up a host inkl. your app, the dependencies (like redis, mongodb,..) and up you go. Your app will be online in a short time inkl. ssh access to the VM.

PS: Signup is done via the CLI. I think this is a trend 😉

Vagrant shell script

Working with several Vagrant boxes in parallel can be tricky. So today I wrote a small shell script to help me here. It will

  • start the VM (if not already running),
  • Login into the VM via SSH,
  • suspend the VM after exiting the VM (if you want)

Shell script:
#/bin/bash
if [ -f ./Vagrantfile ]
then
if vagrant status | grep -q "running ("
then
echo Box is already running
else
echo Starting box ...
vagrant up
fi
echo Login in ...
vagrant ssh
read -n1 -p "Suspend box ? [y,N]" doit
case $doit in
y|Y) vagrant suspend ;;
n|N) echo OK ;;
*) echo OK ;;
esac
else
echo No Vagrantfile found!
fi

maven and UTF-8

There are a lot of places (>5)to set the UTF-8 encoding for your maven project. But only one is important! So don't forget to set this in your maven parent pom:

<properties>
  <project.build.sourceEncoding> UTF-8 </project.build.sourceEncoding>
</properties>
