Ruby on Rails Tutorial: Learn Rails by Example | Ruby on Rails 3 Tutorial book and screencasts | by Michael Hartl Michael Hartl Contents Foreword My former company (CD Baby) was one of the first to loudly switch to Ruby on Rails, and then even more loudly switch back to PHP (Google me to read about the drama). Though I’ve worked my way through many Rails books, this is the one that finally made me “get” it. The linear narrative is such a great format. Enjoy! Derek Sivers (sivers.org) Founder, CD Baby Acknowledgments The Ruby on Rails Tutorial owes a lot to my previous Rails book, RailsSpace, and hence to my coauthor Aurelius Prochazka. I’d like to acknowledge a long list of Rubyists who have taught and inspired me over the years: David Heinemeier Hansson, Yehuda Katz, Carl Lerche, Jeremy Kemper, Xavier Noria, Ryan Bates, Geoffrey Grosenbach, Peter Cooper, Matt Aimonetti, Gregg Pollack, Wayne E. About the author Michael Hartl is the author of the Ruby on Rails Tutorial, the leading introduction to web development with Ruby on Rails.

Things To Tweak / Fix After Installing Ubuntu 11.04 Natty Narwhal A note before reading this post: before giving up on Unity without giving it a try... don't. Try Unity for a few days - yes, it's not a finished product but it's actually quite interesting - and if you don't like it then switch. If you've just upgraded to Ubuntu 11.04 Natty Narwhal, there are probably a few things you'll miss, so here is how to get them back as well as some other things you may find useful. Install CompizConfig Settings Manager and Tweak Unity to better suit your needs: sudo apt-get install compizconfig-settings-manager Then search for CompizConfig Settings Manager in Dash and you'll find the Unity-related options under the "Unity" Compiz plugin. Using CCSM, you'll be able to tweak the Unity launcher reveal mode, hide behavior, change some Unity-specific keyboard shortcuts, change the Unity launcher icon size, the top panel opacity, tweak various animations and more. Another tool for configuring some hidden Unity settings is Dconf-editor. sudo apt-get install dconf-tools

10 things to do after installing Ubuntu 11.04 So you’ve downloaded or upgraded to the latest release of Ubuntu – the nominal Natty Narwhal – but what now? As is now tradition around these parts, we present you with a list of 10 post-install tips/ideas to make your time with the Narwhal less of a splash in the deep end and more of a serene swim… 1. Read about the new features Ubuntu 11.04 comes with so many new features and tricks that it’d be all-to-easy to miss some out. Check it out at omgubuntu.co.uk/natty 2. Even the Ubuntu team isn’t perfect – and chances are there may have been some last minute updates added to Ubuntu after the ISO you downloaded was built.

Due to legal reasons, Ubuntu can’t ship things like patent-encumbered codecs for playing back things like MP3s, .WMV videos or encrypted DVDs. Graphics Ubuntu should automatically detect and alert you that 3D drivers are available. 4. But not to worry!

Heroku | Cloud Application Platform Tom's Hardware US Ubuntu, like any Linux distribution, is just that: a distribution. Linux distributors do not develop everything that goes into a distribution; they must rely on a myriad of open-source software projects to compose the bulk of their end-product. Let's take a moment to see what really makes Ubuntu Ubuntu. One Kick-Ass Kernel Ubuntu 11.04 features version 2.6.38 of the Linux kernel, which benefits from the now-famous 200ish lines of code that (purportedly) improve system performance substantially. LibreOffice Ubuntu kicked Oracle's OpenOffice to the curb in favor of the Document Foundation's LibreOffice. Banshee Banshee 2.0 unseats RhythmBox as the default music manager in Ubuntu 11.04. Like RhythmBox before it, quick access to Banshee's playback controls are now accessible via the volume indicator applet in the top panel. The table below lists other essential default software included in Ubuntu 11.04: Ubuntu Software Center 4.0 Ubuntu One System Settings/Control Center
