comment Why not create an OS that runs in ram?
I will address one point of your question: filesystem. The point of a filesystem is not to store data on a disk; it is in fact a form of database that allows you to store an arbitrary amount of arbitrarily-sized files in a contiguous memory space. Most filesystems are optimized for sequential access, a situation not applicable to random access memory, but other than that, the problem set remains the same. Also, all OSes run in RAM. All of them can work (some better than others) without a hard drive. Since memory is not cheap, we have hard drives that provide more long-term access to data

comment Can a website see/know my MAC address even if I use a VPN?
He is probably talking about online games like World of Warcraft and such. These games have access to hardware information and may therefore report back statistics to the servers. For example, if it is against the rules to have multiple accounts, the server could raise a flag based on the MAC address of your computer, since this number is (probably) universally unique. The MAC address check is more reliable than an IP check, since proxies are easily accessible.

comment Should I connect my 2nd monitor to integrated or discrete graphics to maximize 3D performance on the 1st monitor?
Many mainboards will not allow you to run off the integrated graphics adapter while you are using an external card. Have you tried it out first?

comment Strange magnets in Dell Vostro 3460
Fun fact: many laptops rely on magnets to detect if the lid is closed (it used to be done with a mechanical switch, but these are often unsightly and tend to break). In this instance, the magnets in the speaker could also be detected by a magnetic sensor hidden inside the frame around the display.

comment What to do if kill -9 doesn't work?
@BadPirate, just let it be, zombie processes do not consume resources, apart from the tiny space it requires to be shown in the process table.

comment How to easily bounce arbitrary connections through known SSH server, to avoid port firewalling
This is almost exactly the answer I was going to post (could not because I need more rep to post an answer before 8 hours has passed) however I would add the "%p" percent_replace instead of the hardcoded port 22 to the netcat command. This allows one to specify an arbitrary port number to connect to. Oh and I used sed instead of cut.
