Last updated: September 27, 2013

Ubuntu 13.10 Saucy Salamander is going to be released on October 17th. I’ve installed the final beta on my laptop. If you’re not comfortable with Ubuntu’s default window title buttons (minimize, maximize, close) location, you can easily move them to right via following steps.

That’s it. Enjoy!

Task Coach Todo Manager landed in Ubuntu 13.10’s Software Center

Last updated: September 24, 2013

As you may know, Task Coach is a free flexible open source todo manager featuring hierarchical tasks. It grew out of frustration about other programs not handling composite tasks well. In addition to flexible composite tasks, Task Coach has grown to include prerequisites, prioritizing, effort tracking, category tags, budgets, notes, and many other features. However, users are not forced to use all these features; Task Coach can be as simple or complex as you need it to be.

Task Coach has reached 1.3.32 with lots of bug fixes. It has been added to Ubuntu 13.10 Saucy’s universe repository, so it can be easily installed via Ubuntu Software Center.
