Why is the Intel HD Graphics driver called i915?
The only references to i915 I can find are indeed to the linux kernel driver for the intel chips. Intel just seems to call them HD graphics whatever.
history
What’s the story behind Super Cow Powers?
As we know, apt-get has Super Cow Powers and aptitude does not:
Why is ‘umount’ not spelled ‘unmount’?
I am wondering if there is any historical or practical reason why the umount command is not unmount.
What do the large computers that real terminals were connected to look like?
I am studying the history of computers to better understand why Linux terminals work the way they do. I have read that in the mid 1970’s to the mid 1980’s, most people used real terminals (as opposed to terminal emulators) to communicate with large computers, this is an example of a real terminal:
Why does no one use the true Bourne shell as /bin/sh?
I’ve noticed that basically no system I’ve ever worked with has /bin/sh as a real executable. It’s always a symlink to dash, bash in POSIX mode, or something similar.
Why is there a Linux kernel policy to never break user space?
I started thinking about this issue in the context of etiquette on the Linux Kernel Mailing list. As the world’s best known and arguably most successful and important free software project, the Linux kernel gets plenty of press. And the project founder and leader, Linus Torvalds, clearly needs no introduction here.
Why is dmesg called dmesg?
Is there any explanation/history behind the name of the command dmesg (which prints out some kernel messages)?
Where is “export var=value” not available?
I have picked up — probably on Usenet in the mid-1990s (!) — that the construct
History of Bash globbing
Is there a historical reason why Bash “globbing” and regular expressions are not identical? For example, I believe that in Bash [1-2]* matches anything that starts with a 1 or a 2 followed by anything else, while as a regular expression [1-2]* would match only a sequence of 1s and 2s. My Bash scripting and REGEX foo are both pretty weak and I regularly run into problems associated with these differences which made me curious was to why they are different.
