"Bokeh" is a term used by photographers to praise the out-of-focus areas of a photograph.

Researchers at MIT have figured out how to exploit bokeh so that they can read 3mm barcodes with 2.5 micron elements at a distance of 4 meters with an off-the-shelf camera!

The "bokode" dot …

Did a final training hike around Lake Geneva the other day. Five hours in the rain with full packs, 14 miles or so. Felt fairly good about it until realizing: "So instead of around a lake, it's 4000' of vertical. Take a break, put your pack on and do it …

Researchers say that tone-deafness has a physiological basis: few neural connections between ... uh ... the frammitz and whatzitz lobes.

I think I may be tone-deaf. On the other hand, I may just have been lazy in music classes (I was lazy in all my other classes). I absolutely love music but …

From John Montgomery comes word that Microsoft's Popfly project has been cancelled. I was bullish on Popfly, predicting that it would become the power-user's entrance to Silverlight.

I have had a history of wishful thinking about "restoring the bridge between power users and programmers." I think Microsoft's Powershell is incredible …

I love my original Kindle. But the Achilles Heel of the Kindle has always been technical publications. The original Kindle does not have the screen real estate and formatting engine to properly deal with equations, graphs, and, most importantly for programmers, source code. Although it is possible to view some …

Apropos my recent discovery of camera heading in iPhone metadata comes word of a petition for Apple to create functions that would allow Augmented Reality development on the iPhone:

Augmented Reality are applications that combine computer-generated imagery (or text) with imagery generated from …

Further to last night's post and based on some carefully aligned photos, I am a little disappointed to conclude that the EXIF value GPSDirectionRef that the iPhone 3Gs inserts is (only) the camera's magnetic heading expressed as a rational number and not (as I'd hoped) the camera's 3D orientation in …
