Emacs does indeed have a plugin for this called "undo-tree". I think it is missing the ability to specify a time to go back by, but you can view the timestamps in the tree visualization.

For anyone that uses emacs, there is an excellent plugin "undo-tree" that solves this problem in a slightly different way. Everytime you undo a series of actions and then perform a new action, it creates a branch in the "tree". You can then visualize the tree and move through it quickly your entire buffer history.

You hit the nail on the head. All of that on top of the fact that he is comparing a top of the line GPU against a mediocre i3 processor. GPU to CPU comparisons are always apples to oranges, but this is pretty bad.
I would like to see an OpenCL kernel that is run on both the GPU and CPU to possibly even the playing field a little.

I wouldn't say GPUs are killing off MPI. You still need some way to pass data between nodes/GPUs (most of these datasets can't fit within a single GPU). What you are seeing though, is less and less use of the CPU. If code developers decide to use GPUs, they try and move their data onto the GPU and keep it there for as long as possible (data movement across PCIe is a killer for performance). ORNL's new machine Sumiit [1] will have 1/4 the nodes of their current machine, Titan, but multiple GPUs per node. Thus emphasizing the move away from CPUs and onto GPUs. Again though, there are still 3K nodes and you need some efficient way to pass data between those nodes.

Only if they leave the photo as a losslessly compressed png. They might convert to a lossy JPEG on upload, which means your data is toast.

Seems much nicer than coding directly for CUDA or OpenCL

First the internet revolutionized music and eliminated record stores
Then it revolutionized videos and took down video stores
It didn't stop there, and moved on to bookstores and wiped them out.
And now its taking out brick and mortar stores in general.
Honestly, I LOVE IT! The internet is so great. Anything that gets stuff in my hand faster or easier is great in my eyes.

so this is basically BOINC but also allows for-profit/non-research companies to tap its resources

Not really. "It doesn't really use any parts of Wave's collab stack...We only really use the Keyboard signal event stuff from Wave since it is a pretty great library" -Jamie Yap's comment on g+ post.
