Linux is only free if your time has no value.
I eat and drink at my desk, but I'm a tidy eater.
I use a really simple calendar program on my computer.
My one purpose in life is to serve as a warning to others.
Using these toolkits is like trying to make a bookshelf out of mashed potatoes.
See, unlike most hackers, I get little joy out of figuring out how to install the latest toy.
And when the time comes to replace the O2 I have today, maybe my next machine will run Linux.
Software Engineering might be science; but that's not what I do. I'm a hacker, not an engineer.
Mostly I use the O2 as an X terminal, however, running my apps on Linux and displaying remotely.
If you give a hacker a new toy, the first thing he'll do is take it apart to figure out how it works.
