My take on OpenStack proects, Congress, part 1 of 10 <http://sarob.com/2014/03/my-take-on-openstack-projects-congress-part-1-of-10/> Sean Roberts <http://sarob.com/> started a series of posts about OpenStack projects that he thinks are critical and risk of getting lost in the noise. An Icehouse Sneak Peek – OpenStack Compute (Nova) <http://redhatstackblog.redhat.com/2014/03/11/an-icehouse-sneak-peek-openstack-compute-nova/> It seems like it was only yesterday that the OpenStack community found itself gathering in Hong Kong to set the design goals for the Icehouse release. As we entered March development was still progressing at a fever pitch in the lead up to the feature freeze <https://wiki.openstack.org/wiki/FeatureFreeze> for the release but now the dust has started to settle and we are able to start getting a real feel for what OpenStack users and operators can look forward to in the Icehouse release. People don’t like to queue up <http://blog.flaper87.com/post/531cd585d987d24e83f082a5/> Marconi’s developer Flavio Percoco <http://blog.flaper87.com/> has a crazy idea: let’s get rid of queues. How wacky is that? OpenStack community training <http://sarob.com/2014/03/openstack-community-training/> The OpenStack community training project <http://docs.openstack.org/training-guides/content/> has been working since July 2013 to provide a structured training program to enable skill development for maintaining, consuming, and contributing to OpenStack. The team iscontinuing to increase the accuracy and usability of the documentation and training by engaging with user groups and community members across the world. Get familiar with this project and consider helping it out. The road to Juno Summit – Atlanta 2014 * *Redeem* *your invite code NOW*!
