Install Eclipse Galileo (3.5) on Ubuntu Jaunty (9.04)

Eclipse 3.5, codenamed "Galileo," was released this week! While there is a team actively working on building an Ubuntu deb package, they do not yet have a package yet for Eclipse 3.5. I put together some super simple instructions for installing Eclipse 3.5.

I am going to perform a per-user installation into my home-directory. If multiple people use eclipse on the same computer, you may want to modify these instructions to install into /opt/. I am going to put the installable in ~/bin/packages/eclipse3.5. First, create the installation directory (change according to your own tastes)

mkdir -p ~/bin/packages
cd ~/bin/packages

Now download the appropriate tar.gz file from eclipse. I am going to grab them from Amazon's Cloudfront.

For 64-bit Ubuntu:

wget http://d2u376ub0heus3.cloudfront.net/galileo/eclipse-java-galileo-linux-gtk-x86_64.tar.gz

For standard 32-bit Ubuntu:

wget http://d2u376ub0heus3.cloudfront.net/galileo/eclipse-java-galileo-linux-gtk.tar.gz

Now unzip, and rename the directory (I want multiple versions of Eclipse):

tar xzvf eclipse-java-galileo-linux-gtk*.tar.gz
mv eclipse eclipse3.5

Great, almost there. I am going to create a file so that I can launch eclipse from the command line. Create a new file ~/bin/eclipse, and in that file, put:

#/bin/bash
`~/bin/packages/eclipse3.5/eclipse -vmargs -Xms128M -Xmx512M -XX:PermSize=128M -XX:MaxPermSize=512M &> /dev/null` &

(You can later change these values if you get out of memory issues from Eclipse.) Lastly, make the file executable:

chmod u+x ~/bin/eclipse

Install plugins

Yet again, Eclipse has changed its update manager (each time it gets better). I am going to add a few plugins for Python, Clojure, and Mercurial. If you go to Help > Install new software, click the "Available Software Sites" link, and add your update sites. For me they include:

Add Icon to the Panel I like having an icon on my panel to quickly launch Eclipse, like so:

To do so, right click on your panel in a place with no other panel tool. Select "Add to Panel" then create a "Custom Application Launcher". You can enter /home/<USERNAME>/bin/eclipse (put in your username) as the command to run, and if you click the icon on the left, you can use the Eclipse icon in ~/bin/packages/eclipse3.5/.

Leave a comment if you run into issues or have a better method! You can also see my previous instructions for Eclipse 3.4, if you run into any issues--there were lots of great comments!

Vanderbilt Projects in the News

Some of the projects that I have been involved in at Vanderbilt University's Informatics Center have been featured in the news recently:

  • The New York Times had a feature about our use of the ILOG (now IBM) business rules engine to send out pager or SMS messages to physicians when patients have critical lab results.
  • Infection Control Today had an article about our Sepsis detection application which monitors patients' vital signs and lab results in real time to alert physician to patients who may have sepsis.

tdaemon and virtualenv

I ran across tdaemon, which automatically runs your test suite when you make a change to your source code. It is very helpful when developing. One issue I had was running the tests when tdaemon needs to monitor a huge number of files (as occurs when I have a virtualenv environment in the same directory, which has more than 100MB of code and binaries). I committed a few changes to tdaemon to allow the user to ignore any directories. For instance, if you want to ignore a virtualenv directory called "env" and the "build" and "dist" directories from distutils:

tdaemon --ignore-dirs=docs,build,env

You can even use it with any of the other tdaemon test programs, such as Django:

tdaemon --test-program=django --custom-args="myapp" --ignore-dirs=env,docs

I also uploaded tdaemon to PyPi and have tdaemon install as a script, so you don't need to keep the tdaemon.py file in your directory. Right now all the changes are on my personal fork of tdaemon on github, but hopefully will end upstream.
