Upgrading OpenSUSE 10.3 to 11.1

In summary: very smooth, much better than 10.1 to 10.3 because I didn't try to do it on line, but with an upgrade DVD.
Minor problems with the graphics card driver and monitor but they were easy to fix.

Some niggles with things like DNS but again, it was just a case of redoing tweaks from 10.3 that had been undone by the upgrade.

Migrating from VMWare to Sun's Virtual Box

Today I went to start Windows as guest in my Ubuntu install of VMWare and, boom, VMWare has broken itself during one of the prior kernel updates (because it doesn't use DKMS or release patches quickly enough).
There had recently been a good thread on this on the Manchester Linux User Group's mailing list, so I decided to give migrating to something that more sensibly works a go.

What does AIR application install error "Error# 5100" mean ?

Sometimes when installing an AIR application, the installer refuses to proceed with the mysterious 'Error# 5100'.
This doesn't appear to be documented anywhere, but it actually means the temporary file space is full (i.e. /tmp/ on Linux).

Guess the 100meg cap on my tmpfs wasn't enough, eh :-)

Remove 'unverified server' pop up in AIR

The problem:
Every time some AIR applications start, they give a prompt saying ’trying to connect to an unverified server baz.com (on port 443). Do you trust this server ?’.
Clicking ’always’ (out of 'always', 'this session' and 'never') doesn't work, and it always asks the next time anyway.
 
The solution:
Visit https://baz.com in your web browser, and look at the certificate information for the site (on FireFox, click to the left of the address, then press 'more information').

Adobe gives AIR as early Christmas present

Adobe has today released the AIR run time for Linux, bringing full feature parity to the existing Windows and Mac versions and making AIR truly cross platform.

As a Flex developer, I'm far more likely [node:1524,title="to use AIR"] to build any desktop components of applications (or take web applications offline entirely) than just about the only real competition, Java.

Cheers Adobe, an excellent present to go into the Christmas break and next year with !

Who's rewriting my /etc/nsswitch.conf, eh ?

First my OpenSuSE machine at work decides to have it, and now I discover the reason why my Kubuntu laptop has been having horrible intermittent DNS resolution problems.
The offending entry in both cases was on the 'hosts:' line and said something like 'mdns4_minimal [NOTFOUND=return]' part away along.
At work, this utterly screwed up any attempt to resolve '.local' DNS names, which just happens to be the recommended way MicroSoft Active Directory is used, so it had to go there.
