Nano Stonehenge in 3D

Some one worked hard to move all these rocks around to create a fire pit. This is in a pretty obscure location, not all that easy to get to. As I stumbled on to it, I immediately thought of Stonehenge, on a tiny scale.

Red/cyan 3D anaglyph – red/cyan glasses needed for viewing. Taken with a Fujifilm W3 stereo camera. Click on photo for full size.

I tried to adjust contrast with Stereo Photo Maker, which I did, but it seems to have gone pink too 🙂 (Update – duh – I only adjusted the red channel – duh)

Lytro demonstrates features that could be used for 3D

Lytro is the “light field” camera that enables the photographer to adjust focus long after the image was captured. This means changing the depth of field after, not before, taking the picture.

Watching this demonstration video of Lytro’s perspective shift capability, it is a small step to using this to create stereoscopic-like 3D images from an individual Lytro photo:

Why Youtube may sometimes slow to a crawl

Global Caches Everywhere? | A Systems Approach.

Google Global Cache (GGC).  GGC is a cluster of Google provided servers installed inside an operator’s network to improve performance by caching popular content locally.  Serving content from the edge of an operator’s network eases backbone congestion and relieves traffic on peering and transit links, saving cost and improving QoE.

Some of us live in the wrong cities and watch videos that have not been propagated to servers across the network. Youtube likely replicates popular streams across more servers – whether those servers are close to you “depends”. Anyone else in your neck of the woods watching that video? If yes, it might have been propagated to your area, but if not, it sucks to be you.

This explains why the top viewed, top rated videos all stream great, but the obscure videos I sometimes watch (like sample video output of obscure cameras) never get cached locally to me.

Or so the theory goes!

I’ve done quick tests on an iPhone, an iPad and a Windows Phone, and the Android emulator (my Android phone is kinda taken apart for some experimental work). Looks okay to me.
