My Final Project

Find free spaces in university labs:

• find out if a machine is free, occupied, or turned off
• find out how long any occupied machine has been logged in for (in case someone forgot to log off)
• find your friends! (so you don't need to study alone... or so you can study alone)

Killed by covid-19. Because now nobody is on-site.

How I built it (what's the stack? did I run into issues or discover something new along the way?)

Frontend uses:

• Bootstrap 4
• JavaScript (and unfortunately, jQuery)

Backend uses:

• Python / Flask
• Redis
• Go (for the SSH bot, that fingers every machine)
• Docker

Some tricky things include working around:

• uni breaking the finger command
• a bug where some users will still have processes running after they log off, making it harder to determine if someone is logged on / how long they have been logged on for

I also integrated with the university's authentication system, so I built a library called 'gosign' to make it easier for others to integrate CoSign authentication into their own systems.

client, err := gosign.Dial(&gosign.Config{
  Address: "www.ease.ed.ac.uk:6663"
  Service: "betterinformatics.com"
  TLSConfig: &tls.Config{
    ServerName:         "www.ease.ed.ac.uk"
    Certificates:       []
