Xubuntu 13.10 - Same again please bartender ~ Everyday Linux User Introduction I reviewed Xubuntu 12.10 just over a year ago and it is still one of the more popular articles on this site. Last week I installed the latest version, Xubuntu 13.10 to see if much has changed.

Customizing Fedora 25 for Developers I dusted off a 4 years old Lenovo ThinkCentre Edge 71z Tower desktop and Lenovo IdeaPad G400s notebook. They are, respectivelly, a 2nd generation Core i5 SandyBridge 2.5Ghz and Core i3 2.4Ghz, with 8GB of RAM in the Tower and 4GB of RAM in the notebook.
