Fixing the laptop

This kernel seems to be working. stick to this one. uname -r 2.6.32-220.el6.x86_64 grabbing backups from other laptops - again!!! grrrrr!

Installing Google Chrome on CentOS 6.x x86_64

Download "64 bit .rpm (For Fedora/openSUSE)" sudo yum install redhat-lsb sudo rpm -Uvvh sudo rpm -Uvvh google-chrome-stable_current_x86_64.rpm

CentOS yum message - yawn

WFT is this crap now? after yum update... There are unfinished transactions remaining. Please run yum-complete-transaction as root. yum gimme a break!

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
