Right, no scripts running means virtually no attack vectors. Perhaps overloading the buffer by downloading a large webpage? But that's about all I can muster.
I have been taking it. So far I've found it pretty good (I took linear algebra many years ago in college and didn't remember most of it), even though I don't really like the amount of reinventing-the-wheel (e.g. writing your own vector class) involved.
In Windows 3.1, CTRL-ALT-DEL will allow you to kill a hung application. If no application is hung, it will tell you to press CTRL-ALT-DEL again to reboot.
While I wish Matlab just disappeared, Python is still far from replacing it in some fields (e.g. electrical engineering), in no part due to the massive amount of toolbox available for it.
Used to run Arch until recently, but moved to Ubuntu when 13.04 came out.
Currently using Ubuntu with MATE (haven't bothered with Unity in quite a while, considering my experience with it in previous Ubuntu versions was quite underwhelming - might try it again someday) and - surprisingly - not missing Arch that much.
