As far as I know yes. From personal experience you can just `cd ..` your way out to the top parent directory and see all the orgs which use the system. I could see MIT and JPL(?) users from my cmu account and you can view the other users for each org (at least for MIT and for some of the other unis, I could never get the JPL stuff to load.) You can view the usernames and their public folder but nothing else.
There's also a lot of content from previous CMU classes. It was interesting to stumble upon some older 15151 course material which used some programming to prove certain theorems. They don't do this anymore (I'm not sure they even did this in the first place) and I'm assuming even for CMU CS students, expecting them to be able to programmatically prove theorems in a freshman class is a bit much. Cool stuff to root around in.
I found this randomly in my high school library and I "borrowed" it for the summer. It was honestly the best intro to computer engineering courses I've ever read. It was incredibly easy to understand even for a high school age me with basically no knowledge of electricity or physics.
It starts from the basics of people who used switches and electromagnets in the past, and more or less follows the history of how computers were made, which personally helps me understand the logic behind some of the weirder design decisions. (sidenote: I feel like history is great for understanding most strange decisions)
It also helped me breeze through the circuits and digital logic section of my intro ECE course, and was accurate enough to inspire me to build an 8-bit adder in Minecraft upon finishing the book. I really miss the days of having that much free time, if you have someone who is an avid reader and loves electronics, this book is amazing.
