Elm Destructuring (or Pattern Matching) cheatsheet

Should be work with 0.18

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

CentOS 7 Kickstart File & How to build an (auto install) ISO

CentOS 7 Kickstart File - HOWTO Build ISO

There is so much documentation online from RedHat and CentOS about this topic - it's sad that I am writing this. But the real state of documentation on this topic (CentOS 7 + KS + ISO = Bootable DVD) is almost non-existent.

I found this: http://smorgasbork.com/component/content/article/35-linux/151-building-a-custom-centos-7-kickstart-disc-part-1

Which I greatly appreciate and +1, but the documentation is half-baked and there are numerous errors.

Finally... FINALLY! After four days of banging my head, I got this to work. Hopefully someone else will be able to do this in a few hours, instead of blowing their weekend like me. :(
