First used UNIX 6th edition in 1975 at the University of Waterloo and first used Linux 0.99pl12 in 1993. I remember getting X with twm runnning using a socket emulator package that used UNIX pipes to simulate network sockets.

comment mv file without write permission to the source file
Actually, sticky bits were used to indicate binaries that should not be cleared from memory after execution finished because they would likely be used frequently. That's how it was in 1976. Somewhere along the line kernels evolved and this was obsolete, but there was this bit hanging around with nothing to do, and the chmod command knew how to set it already.

comment Problem : how can I copy/paste this in vim?
Us vi oldtimers are always counting chars, words or lines because we often use things like y7l, c3w or d5d.

Use the bisect module in Python to do this.

comment How is the linux graphics stack organised?
DRM and KMS are more about device drivers that now have to communicate over a dedicated internal network connection to a graphical rendering CPU on the graphics card. This may be part of the graphical stack, and it may not (i.e. Amazon EC2 Linux).

comment How is the linux graphics stack organised?
I would not agree that the kernel is at the bottom of the stack. Of course, device drivers do use kernel services in order to get privileged access to the hardware, but an X application is talking out the network so there are more layers beyond even the network card.

comment Best way to remove bytes from the start of a file?
C is not a scripting language so I don't recommend this. Consider that you might stick this dd command in a shell script for future use. But in future the number of bytes to skip may be different in which case you are back to square one. But with a Python, PERL or Ruby script, you simply edit the skip count, and run it, or make it more general and have the skip count as an argument. In 197s it was necessary to figure out how to do the job without resorting to compiling C code, but today we have more powerful tools standard on UNIX OSes.
