You know you're in trouble when you have an operating system which is at the pinnacle of technology and championed by a very vocal group; which has the support of thousands of developers from around the world; which is supported by a body which aims to "protect and standardise". Welcome to the would of Linux.
If someone stopped me on the street and asked me what the biggest problem was with Linux, I would instantly say that the fragmentation in place is muzzling progress....
That's right. A company who many in the Linux world consider fashionable to hate, is one which commands respect from me. Why? Well the reason is that Adobe actually gives a damn. I know, I know, Flash is a bit of a horror show at times, but the fact that it is available on all major operating systems (even OpenSolaris for those poor fans who are left).
But most importantly, the fact that Adobe supplies a dedicated repository for Ubuntu and Fedora users shows again that Adobe cares....
Those of us who use Ubuntu will be aware that Ubuntu has got a "partner repository", a repository which contains proprietary software which, by nature, cannot be included in the main repository. It is an idea which I personally think is excellent, as it allows software which goes against the principals of Open Source to be included for the benefit of standard users.
It's such a good idea that I'm amazed no-one else has copied it. Those who use a distro outwith the Ubuntu...
Basically the scenario is this: I don't do a whole lot of programming anymore (in fact, the last time I wrote a C program, useful or not, was probably a good few months ago), I'm somewhat of a gamer (Neverball, LTris, various old games in DOSBox), and I like all the pretty bling on my GPU-composited desktop (i.e. I like my Compiz ).
...so why am I using Linux? Am I kidding myself?...
When you write scripts dealing with setting up or analyzing network interfaces you will eventually run into the task of converting a netmask from one format into another.
Typically, the setup of an ethernet TCP/IP network interface consists of an IP address, a netmask, and a broadcast address. Unfortunately for you as a novice, the two tools ifconfig and ip show the same (or similar) information in a different format.
