Fixing Papercuts in Ubuntu Server Edition

Just about a year ago, Ubuntu developers undertook the first “100 Papercuts” campaign to fix trivial bugs on the desktop.  But servers get papercuts, too, and the server team has been working for the last several months on its own papercut-eradication effort.  Here’s a look at what’s been done so far, and what’s planned for […]

Editing PDFs On Ubuntu

It would be great if all PDF files could be easily manipulated without relying on bloated, proprietary, update-obsessive applications (I’m looking at you, Adobe).  But the fact that that’s not the case doesn’t mean Ubuntu users are out of luck when it comes to editing PDFs.  Here’s a look at some of the PDF editors […]

VirtualBox vs. KVM on the Desktop: A Comparison

Running Windows Files in Ubuntu 10.04: The Wrong Approach?

If you use Windows software on Ubuntu 10.04, chances are you’ve encountered the new feature in Lucid Lynx that prevents .exe files from being run without the executable bit set.  This might be good and well for some users, but is it really the best approach to security?  Here are some thoughts.
