"NASA is paying $424 million more to Russia to get U.S. astronauts into space, and the agency?s leader is blaming Congress for the extra expense. NASA announced its latest contract with the Russian Space Agency on Tuesday. The $424 million represents flights to and from the International Space Station aboard Russian Soyuz spacecraft, as well as training, for six astronauts in 2016 and the first half of 2017. That?s $70.6 million per seat ? well above the previous price tag of about $65 million. Russia currently provides the only means of getting people to and from the space station, and its ticket prices have soared with each new contract."

"Keyboard shortcuts are combinations of two or more keys that you can use to perform a task that would typically require a mouse or other pointing device. Keyboard shortcuts can make it easier to work with your PC, saving you time and effort as you work with Windows and other apps."

""You are UCLA students. The brightest of the bright. Let's see what you can accomplish when you have no restrictions and the only thing that matters is getting the best answer possible."

Once the shock wore off, they got sophisticated. In discussion section, they speculated, organized, and plotted. What would be the test's payoff matrix? Would cooperation be rewarded or counter-productive? Would a large group work better, or smaller subgroups with specified tasks? What about "scroungers" who didn't study but were planning to parasitize everyone else's hard work? How much reciprocity would be demanded in order to share benefits? Was the test going to play out like a dog-eat-dog Hunger Games? In short, the students spent the entire week living Game Theory. It transformed a class where many did not even speak to each other into a coherent whole focused on a single task-beating their crazy professor's nefarious scheme."

I love hyper-v. I especially love hyper-v running on windows server 2012 in a failover cluster configuration. It truly is a wonderful environment to administer windows servers. With this said, the error logging leaves a lot to be desired.

I've just spent the better part of two days trying to work out why live migration of servers between cluster nodes wasn't working. The error message which Microsoft helpfully give you when this happens is simply:

Event ID: 21502 Source: Hyper-V High Availability Virtual Machine [VM NAME] Live Migration did not succeed at the destination

And over on the hyper-v host you were trying to migrate the virtual machine onto you'll get the equally as amazing Microsoft-Windows-Hyper-V-High-Availability-Admin log entry of:

Source: Microsoft-Windows-Hyper-V-High-Availability Event ID: 21111 Description: Live migration of 'Virtual Machine <VM NAME>' failed.

Oh thanks, it didn't work because it failed.

Finally after reading many a technet article and support thread I stumbled onto the fix. It was simple. Here's the details for anyone else who suffers this problem:

• On any node in your hyper-v cluster, open up Failover Cluster Manager
• Select the cluster name
• In the bottom right corner of the manager window, click Take Offline
• Again in the bottom right corner, under More Actions, click Repair
• This will bring the cluster back online and magically fix the mysterious problem causing live migrations of VMs to fail

Best of all, it will do this with out any disruptions to running VMs. Enjoy!
