Cross-platform UI with Qt4 and Ruby - Mac/Linux HOWTO

Filed under

Today I’ve spent the day working on figuring out how to make UIs using Ruby and Qt4. If you haven’t heard of it, Qt4 is an awesome UI framework written in C++. Since C++ is way too much work, some great KDE devs wrote a bindings generator for Qt4 called qt4-qtruby. While this package is fairly “linuxy”, it’s pretty easy to build it on Mac OS X too, making it possible to write GUI programs for OS X without having to delve into RubyCocoa which has too much hackiness (in my opinion), or even worse, Objective C. Furthermore, your code that you write on OS X will look great on Windows and Linux too!

Starting from scratch

First, install Ruby. If you’re using Linux, you’ll probably use the package manager to install Ruby and the Ruby development libraries! (Ubuntu will run sudo apt-get install ruby irb ruby-dev) OS X Tiger ships with Ruby by default, but you’ll want to install an updated version, via the Ruby one-click installer, then disable the old Ruby by using the following command:

At the Heart of OpenStack Evolution

As it matures, OpenStack's parallel to Linux is clearer. Linux emerged 20 years ago as a somewhat exotic challenger to proprietary operating systems. Today, it is one of the most popular and widely used OSes. However, Linux still exists in a market of mixed use. It's likely that OpenStack will be subject to the same effect, becoming a viable option among a number of cloud infrastructures. Read more
