Site originally by David Winterbottom (user root).

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

» The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
» If you wish to use your user account, you will probably need to reset your password.

Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Unlock your KDE4 session over SSH

So this first obtains address of the DBUS session, as it's not available by default over SSH. Then it tells plasma-overlay to exit. `kquitapp` is pretty much an equivalent of the qdbus calls.

This is a specialized command for Ericsson CS5.2 - Getting the test case trace on SDP

This command allows to follow up a trace on SDP (CS5.2), at the same time as the trace records are stored in the file with "raw" format.

Trace files in native format are useful to filter the records before to translation from '|' to '\n'.

Example:

grep -v OP_GET <raw-records>.trace | tr '|' '\n'
