Yeah, it's the most do-it-yourself but is pretty difficult if your not extremely comfortable with Linux. I tried to do it a few months back (without too much C knowledge) and couldn't figure out how to cross-compile/link libraries I needed. I got it to boot into a shell (without login). At this point, I could probably do it, but I prefer sticking with really minimal distros like CRUX and Void.
There are a few reasons they split off home and root. It makes recovery simpler, and allows you to share the partition between multiple environments - which is useful if you dual boot.
I personally rarely make a second partition for home, but I always make a separate partition for /boot. GRUB requires an separate EFI partition to install (which is kind of dumb), and if you decide to encrypt your disk, the boot directory cannot be encrypted.
I think the reason they put swap in these tutorials is that many times people install linux on low-powered machines that require the swap because of limited memory. It's not a requirement to install linux, though. I never run it on installation.
Yes, but what are ways it is possible to break into a car?
Break a window (drawback: sets off a car alarm)
Duplicate or steal the a key (drawback: requires original key)
Steal car when open (drawback: not many people leave there car open)
How could you break in a Lockitron (or prevent someone from using it)?
Steal a persons phone (much easier than stealing a key. A phone is taken out more often than a set of keys)
Cut telephone wires for wi-fi (a little extreme, but possible)
Hack there password.
Besides, how much motion does it require to open a lock with a key? I guess it makes sense to use it to unlock or lock your house remotely, but when have you been in that kind of situation? If someone needs a key, just give them a copy.
How many people use touchscreen monitors for desktop computers, anyway? They make sense for tablets, but mice and trackpads are easier if your using a (physical) keyboard.
