So the "tweet" started:

" ok so that's that! today's news means this season we will be mainly tracking http://review.whamcloud.com/ and http://build.whamcloud.com/ "

For those of you out of the know, the tweet was a reflection that Bryon, Andreas and Peter are all going to be part of team whamcloud by the end of January:

Hurray! http://reg.cx/1M9s

So just quickly, I could not resist poking at the code. You can set up your ssh keys after visiting whamcloud's Gerrit servers:

Full Name James Cuff

With a swift .ssh/config file that looks very close to:
jcuff@srv:~/wham/lustre$ cat /home/jcuff/.ssh/config
Host wham
User jcuff
Hostname review.whamcloud.com
IdentityFile ~/.ssh/wham.rsa

This will get you awesome code goodness to check out:
jcuff@srv:~/wham$ git clone ssh://jcuff@wham:29418/lustre

Then simply:

And then some major *extreme/possible non functional* hackage later...
ubuntu and lustre are lots of "fun" together, we love sk_sleep et. al.!

Ok I have to stop! I don't want to go and spoil all the fun here!

All the fun you can cope with or need to have can be found over here:




Certainly time for me to pass this over to my much more talented team @ rc.fas.harvard.edu, who have already stood up PB's of the older non wham versions of this stuff!

Anyways, go go Bryon, Andreas, Peter and all lustre advocates where ever you may be! Time to make us all proud of what we have, and what we are about to be and build together!!
