Update: Final release is published.
I’ve been using, testing and teaching the beta version for a while. Check links for tutorials of Puppet, Vagrant and other new tools.
New Packages & Versions
- Puppet 2.7 – configuration management (Hello Puppet, PuppetMaster)
- Arduino 1.0 – Make Arduino Bots (my book)
- Vagrant – automate virtualization and run headless VirtualBox (Hello Vagrant, Web Development)
- VirtualBox (USB support, packaging to single OVA?)
- Firefox (YouTube without Flash?)
- Miro – RSS video player (YouTube search fixed?)
Fixes to Problems
- Gnome 2 is gone, Unity doesn’t feel ready for productive work yet. Unity is the default user interface with the hiding bar on the left. Fix: use XFCE by installing from Xubuntu CD (link below). Medibuntu switched to XFCE, so did Linux Torvalds.
- Only <4 GB RAM with Xubuntu 32-bit. I already got used to the default PAE (physical address extension) kernel, so that 32 bit Linux can see 8 GB of memory. Possible fix (untested): sudo apt-get install linux-image-generic-pae. Obviously, if you install 64-bit version you can see all your RAM.
- Arduino requires logging on and off before use. Fix: install instead of using a live CD.
Release version of Ubuntu 12.04 LTS is out, download here.
Understand that this is Beta version, don’t install on production systems.
It’s an ISO image, so it must be burned in a special way. Ubuntu: ‘cdrecord foo.iso’ or right click and ‘Write to Disc’. Mac OSX: drag to Application: Utilities: Disk Utility. Windows: Right click and “Burn disc image” or use Infra Recorder “Burn image”.
