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 :-)

Today I was writing what looked like fairly simple code to persist ~60 items in a local database using AIR, and then load them back up at application start-up.

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:

The BBC a while back their intent to use Adobe AIR to make iPlayer work on the desktop of just about everyone.
And now it's happened.

And we thought a lot of bandwidth was being used at work for non-work things last month before we locked off Facebook :-)

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.
