Quickie: Fix /usr/local permissions for Homebrew on Mac OS X

Homebrew is a great way to get unixy software on your Mac. The default install is to /usr/local, and it fixes the directory permissions so you don’t sudo every time. Every so often, however, the permissions can get a little mangled, usually from some other overzealous installer.

This quick fix is just a small modification to the standard Homebrew installer, removing the parts that actually do the installing: Running this command should fix your Homebrew /usr/local install in no time.

Install VR Juggler on Ubuntu Linux – from packages!

Just a brief announcement on a broader, more Google-accessible venue: I’ve been creating and maintaining VR Juggler packages for Ubuntu in a PPA repository. If you’re on Lucid (10.04) or Maverick (10.10), you’re in luck: I have both 3.0 and 2.2 versions created, though at the moment you can’t have both of their dev packages installed simultaneously. I created them primarily for my own use and sanity, but I’m happy to share – getting Juggler to build and package nicely in both 32 and 64-bit was a bit of work.  They certainly won’t win awards for high-quality packages, but I’ve been using them for quite a while and they are easier to handle than a mess of locally-installed versions.

Here’s the Launchpad URL for more info:https://launchpad.net/~isu-vrac/+archive/vr-software

Just run these commands to add the source:

sudo add-apt-repository ppa:isu-vrac/vr-software
sudo apt-get update

(or add ppa:isu-vrac/vr-software to your Software Sources control panel)

Then, you can use your preferred package management tool to install: here’s the “install it all” packages in the Ubuntu Software Center, for example. (Once you have the source added, these links should also work: install VR Juggler 2.2 development packages or install VR Juggler 3.0 development packages)

Enjoy!
