Did the Manhattan Transfer Use Auto-Tune?

I recently came across an allegation on Amazon.com that got me thinking. The review in question is by Andrew Grobengieser, and it is critical of the Manhattan Transfer’s latest album, The Chick Corea Songbook. Grobengieser alleges: As a lifetime fan, I was unbelievably excited to hear of the release of a Chick Corea songbook. And…

High School Prior Art

Based on a Slashdot link, I read a blog post today about the Oracle/Google lawsuit over Java virtual machine patents. Among the list of software patents that Oracle has decided to sue Google with are two that I’m fairly certain that I wrote prior art for. This was in 1983 or 1984 while I was…

Thoughts on 3D After NAB

I just returned from this year’s NAB show, where I was bombarded with 3D demos in virtually every booth. Most of the factors driving this 3D superabundance originate outside of the broadcast industry itself. First, TV manufacturers are hot on 3D as a way to get everyone who just bought an HDTV to upgrade to…

Sniffing iPad Traffic

For a project I’m working on, I was wondering how a particular video-related feature on Apple’s new iPad works. In order to figure that out, I thought it would be interesting to connect a network sniffer in-line with my shiny new iPad, so I could capture and analyze all the network traffic flowing to and…
