IT Tickets. Make all requests here or email. Use this for everything from "install a font" to "my mouse is broken" to "install XXX in Dec10". There is better interface to mange multiple requests here.
IT Service Desk. On level 10 in EC Stoner.
Uptime. uptime systems here.
GPUs / clusters/ research computing. see my page here.
Website. Edit your university (Jadu) webpage here. It will be listed publicly here. It finds publications from Symplectic automatically. To advertise PhD projects on the university's portal, use this. There is no way to list only your PhD projects... Both these system have a delay while marketing checks your content before uploading.
Group websites. Sites like this (vcg.leeds.ac.uk) are run by research groups. They are wordpress installs on WPE. They all use the uni's theme. Apply here.
Dec10. The School's Linux lab on lvl 10 EC Stoner. (named after the PDP-10 terminal in the room). The air conditioning is controlled from the locked office so the room is usually too hot/cold. If your lab is scheduled, you can ask everyone else to leave.
Faculty Linux Computers. You can get an online clone of the Dec10 environment on feng (alternative. Both require VPN). It is also possible to shell into any of the Dec10 machines. They use the module system to access installed software ("module avail" at the command line). I have found a few cases where feng wasn't able to run code which does run in Dec10.
Internet. Generally less than 100Mbs.
