I use linux since 1994. I pride myself into thinking I know well what kind of tool linux can be.
I am accustomed with (and get quite thrilled about) the notion that I will learn something new every day of my life, right until the last one.
Yet, I still get surprised by discoveries like Linux.com's tips of how to print labels with Linux. This was one function on which I had given up all hope when it came to Linux. Well, it feels very good to be proven wrong, sometimes.
