[freejava] Free Java update and key upload reminder (TODAY)

[Tom Marble]

All:

FOSDEM and the Free Java devroom activities are coming soon!

We have a fantastic set of speakers lined up and I'm
sure everyone will learn a lot and have a great time!

Check out the wiki for some practical information including
a shared Google map of FOSDEM sites and information
on how take the train from BRU airport to Gare Centrale [0].
Typically a lot of the socializing (including the Beer Event)
happens around the Grand Place and the conference itself
is at ULB.  There are buses and trams to get from
Grand Place to ULB [1].

Please note that today, SUNDAY, is the last day
to submit your key for the FOSDEM key signing party [2][3].
We originally wanted to leave the time open for
everyone to attend the KSP, but we had too many
awesome talk proposals.  Even if you can't attend
the KSP it's still helpful to submit your key because
then everyone's key will be on the same printout.
Of course it's probably, as always, a good idea
to bring slips of paper (or business cards) with your
key fingerprint for informal keysigning.  In fact it's
been suggested that we do an informal Free Java keysigning.
I have some links for details on keysigning [4].

A sort of "quick and dirty" command line summary
is provided below [5].

I will arrive on Thursday -- e-mail me if you want
to sync up.  I look forward to seeing everyone soon!
