Teach me how to fish - python exception handling

I really do want to understand this documentation: from `pydoc try`

The ``try`` statement
*********************

The ``try`` statement specifies exception handlers and/or cleanup code
for a group of statements:

   try_stmt  ::= try1_stmt | try2_stmt
   try1_stmt ::= "try" ":" suite
                 ("except" [expression ["as" target]] ":" suite)+
                 ["else" ":" suite]
                 ["finally" ":" suite]
   try2_stmt ::= "try" ":" suite
                 "finally" ":" suite

So what exactly does the first line mean?

try_stmt  ::= try1_stmt | try2_stmt

. It's a bit confusing as I know how to implement very simple try statements like this;

try:
    import io
    print("importing io")
except ImportError:
    print("nothing to import")
    foo = None
try:
    import somefunctionthatdoesnotexist
    print("importing ...")
except ImportError:
    print("nothing to import")
    foo = None

Remembering how to use Xen

I have not created a virtual machine with Xen in a few years. I want to create one for GNU BLAG/Linux so that we can upgrade the main box that the team use to build RPM packages. Let's see how this works.

chkconfig --list | grep virt

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

Gnome 3 - what happened?

Right,

Before I dig in and jump on the band wagon. Let me just say in this short and simple post that I gnome 3 is rubbish.

1. Where is the power button in the menu?
2. How does one get a new terminal from the gui and not just show the existing ones?
3. Why change so much so quickly?
4. More of the gnome configurations rubbish. Just gimme a simple gui to make my set my desktop prefernces
5. What Linus said
   

Net flopping

Called Bethere to get the setting for the static IP. Got that and put the router back to the original state. So removed the bridge between the Bebox and the Lyksys router. Net back to normal now but cannot shell into acidhome. Means that I have got to go back and sort it. This box must be back on line as it's the best box that I have...

• public facing bugzilla
• It's got tonnes of disk space
• 3GB of RAM should be more than adequate for MY needs

Grrr!

No VPN at home for now

http://www.craigmayhew.com/blog/tag/vpn/

This essentially means that I will have no VPN at the base. One things that I have learned though is ssh tunnelling. It's really neat. The following allows me to open up the web interface for my router at home, from the browser at any location on hte net.


ssh -g -vv -L 8000:192.168.1.254:80 acidhome

So after that I just type localhost:8000, into my browser and it's just as if I was sitting at home, crossed-legged on the sofa. Heck, just for the sake of it I changed configs and ran a telnet session.

Thanks Alan!
