yeah, I saw that it won't do JS/CSS
but apparently it does provide a link to automatically try to open it in nbviewer....though I haven't tried it yet

yup, just did, it works great
would love to know why these aren't quite rendering correctly up top...
i'm not doing any goofy css/js, just a little styling for the logo

hmm, strange
it does load the logo, but the formatting is a bit weird

this is very flex
@/all a nice thing from philipp keller's talk yesterday: shannon entropy of DCT of an image is a good measure of its "in-focusness"

which makes sense. sharp, peaked spectrum in biological imaging --> uniform blur on camera chip, flat spectrum --> lots of features on camera chip

I'm an imaging newb -- if you have a sharp signal coming from your sample and your camera is in focus, why would this lead to uniform blur on the camera chip?
Also: camera chip == sensor?

sharp spectrum /= sharp image
an image of 1's gives you a super sharp spectrum, but it has no features
ya, camera chip == sensor

ah, cool, makes sense
