DICE software

How do I find out what software packages and versions are installed on DICE?

On DICE Ubuntu: The command dpkg -l gives a complete list of all the software packages installed on any particular system, along with summary information about the package (most lines should start with "ii" - those are the ones actually installed), and dpkg -s package will tell you more about a particular software package.

How does the DICE bash start-up mechanism work?

We've modified bash slightly on DICE. If you want to personalise it you should use the startup files described below.
For full details, type this at a shell prompt:

man bashdefenv

This is how the startup files behave on DICE Ubuntu:

~/.brc is executed every time a new shell starts. Use it for aliases.

~/.benv is executed every time a shell starts in a new environment. Use this to set environmental variables or functions, for example - things which can be exported to subshells.

Cosign

What is Cosign?

Cosign is a single sign-on (SSO) web login technology developed at the University of Michigan. It uses a centralised sign-on mechanism to authenticate users: for Informatics users, this means authenticating to web sites using your Kerberos principal.

Cosign uses login and service cookies to manage the authorization for a cosign-protected website. More detailed information about the design of Cosign can be found on the Cosign website.

Main Informatics website

The main Informatics web service covers the site accessed via the www.inf.ed.ac.uk URL.

Most recruitment and publicity type content is now hosted on the University's central web service, so many of the old URLs will redirect you to www.ed.ac.uk/informatics/ pages.

Official administrative information is now hosted on the intranet site web.inf.ed.ac.uk. Note that here the term intranet indicates that the content is targeted at existing staff and students, it is still publicly accessible to the world.

About the only content left on www.inf.ed.ac.uk are teaching pages, though they are mostly migrated the University's VLE - Learn.
