Obviously there is a lot of advocacy at mojocasts and mojolicio.us, but there are a lot of useful posts outside those channels, for example in PerlMonks and StackOverflow.

When a director gives you a line reading that doesn’t feel right for your character, nod and agree with him or her, then do it the way you know your character would do it. If you’re an actor, always be true to your character; if you’re not an actor, have character, and always be true to yourself… Whatever you do, wherever you go, do something real, make a real product, provide a real service, do something of value. Create something of beauty. — Robert De Niro at Bates

A typical scenario is that you need to access something (running
on a port) on a remote machine as if you were there. For instance,
the web server, mail server, or db server on that machine may only
allow local connections, but you temporarily need access from afar.
As long as you can ssh to the remote box, you should be able to
set up a tunnel (remembering to tear it down when you’re finished).
For example, you configure your router firewall to NAT ssh
connections, but nothing else. Thus you gain fairly decent security,
easy configuration, and the ability to temporarily access most
other things via a simple one-liner.
ssh -f user@remote-address -L 3080:localhost:80 -N
Then point your local browser at “http://localhost:3080/” and you
should see whatever would have been served by the remote
machine at “http://localhost:80/”. Note that in that one-liner,
“localhost” is telling the remote host which machine is the target
of the tunnel. For example, in the same locked-down scenario,
I may want to access the web interface of the router, which
doesn’t provide direct ssh nor external access to :80.
ssh -f user@remote-address -L 3081:internal-router-address:80 -N
Then point your local browser at “http://localhost:3081/” and you
should see whatever would have been seen at
“http://internal-router-address:80/” if browsed from the remote
