I’m running Linux Mint Debian Edition (LMDE), and I needed to install the nvidia drivers in order to develop WebGL applications. Without the nvidia drivers, the display was a little laggy, but fast enough. Not being able to run WebGL, however, was kind of a show stopper.
So I did a bunch of research. There’s a lot of information out there, and only some of it is contradictory, but it’s all confusing. Everything seemed tailored for either Linux Mint or Debian, not LMDE. And there are also a lot of warnings about systems that don’t boot after rejecting the new drivers. All of this lead to a few hours of hand-wringing before I took the plunge.
Turns out it’s really easy. Continue reading →
I was creating a build server for an Android project on a remote web host run by Webfaction, but I was running into a problem when running the ant scripts. I had installed the Android SDK in my home directory according to these instructions, but running ant clean debug threw this error:
Execute failed: java.io.IOException: Cannot run program "/home/stevehb/bin/android-sdk-linux/build-tools/20.0.0/aapt": java.io.IOException: error=2, No such file or directory
I checked, and /home/stevehb/bin/android-sdk-linux/build-tools/20.0.0/aapt existed. I couldn’t see a reason that ant couldn’t find it, so I eventually tried to run it myself.

If you want to set up a remote build machine for an Android project, one of the first obstacles you’ll encounter is how to install the SDK from the command line. Both the SDK installer and AVD Manager are designed to be run graphically. Fortunately, there are some options for command line setups.
First thing you’ll need to do is download the SDK tools. You probably just need the SDK Tools tgz file for a linux install. You do not need the ADT Eclipse plugin, nor the ADT bundle. Those all need a GUI.
Then, after unpacking that file, you’ll need to set up the environment variables and install the actual platform SDKs. There are SDKs for the different APIs you can target (ie, API 15, API 19, etc), so you’ll need to know what you’re aiming at. Google has some old information about how to install those SDKs on a headless machine, but here are all the steps themselves, as well as some caveats.
