A while back I posted a glowing review of the video performance of the T2i / 550D camera. I'm coming back now to review the audio quality and frankly there is not much to say.
The external microphone jack works well, and the T2i still uses AGC (Auto Gain Control) that automatically increases the gain (volume) on the microphone when things are quiet. That's fine for impromptu video where you don't necessary know what the noise levels will be, or aren't using an external microphone. The 7D also forces use of AGC but the 5D2 does not since 2.0.4 of the...
Recently, I posted a article about how much computational power it would take to emulate the human brain, and my calculations were off by a factor of 10. I've corrected my estimates and here are the updated sections:
Emulating the Human Brain
The Blue Brain Project has successfully simulated 1 cordical column on the Magerit super computer (100 TeraFLOPS), and human brain has an estimated 1,000,000 columns.
So with 5.2 ExaFlops, one could emulate 52,000 cordial columns. And that’s 1/20th of enough power to emulate a human brain.
To emulate the entire human brain you would need approximately 100 ExaFLOPs
That's a lot of...
As a brain exercise I decided to try and estimate the total processing power of all the computers on the entire internet, and see if that is enough processing power to emulate the human brain.
Since this is an estimate, I will try my best to figure it out with public data.
Here was my process:
Total Number of Computers
No one knows exactly how many people (computers) are connected to the internet since a single IP address can be shared with any number of pc’s, but the best estimate I was able to find was here: Internet World Stats
They use population statistics...
