Who Needs HD DVD or Blu-ray?

The reason consumer electronic makers are scrambling to end the format war between HD-DVD and Blu-ray is simply because watching movies delivered by spinning discs is a rapidly obsolescing technology. The days of the CD and DVD are coming to an end. The emergence of static memory devices that can store the large amounts of data required for audio, video and images spells the end of storage devices that require physically moving parts. The growth of video on demand over the network and in general networked storage means the only reason the HD format discs are hanging on to viability is that it remains expensive and difficult to send the HD quality video over a network or store it on static memory. The window is closing and unless the DVD makers get their act together their technology will be eclipsed and no one will need a "Blu-ray" player to play anything and those DVD can be used for coasters.

Archives may be one of the best customers for storage systems that spin discs to store large amounts of data inexpensively and permanently, but for consumers of media, the hard disk, the flash storage systems and network on demand storage systems will come to predominate more quickly than anyone thinks.

Minolta Lenses on a Four Thirds Camera

During the summer, I bought an Olympus E-510 digital single lens reflex camera. The 510 is a FourThirds camera and because of the of shallow flange of the 4/3 lens mount it is one of the most flexible cameras on the market when it comes to mounting legacy optics (lenses from traditional film SLRs). A 4/3 camera can mount "legacy optics" or lenses from several other manufacturers made before the DSLR era. Although unintended, this makes FourThirds a revolutionary mount. For the first time not only can a photographer mount lenses from different manufacturers who produce lenses to the "open" FourThirds standard, with inexpensive Chinese-made adapters lenses from nearly any manufacturer from the golden age of SLRs can be mounted as well. Third party adapters can be found for Olympus OM, Nikon, Pentax, Zeiss and Contax. The only one missing from the party was Minolta. I purchased an inexpensive OM to 4/3 adapter from ebay and mounted several OM lenses, a 50mm f/1.8, 50m...

Snowball, the Dancing Bird

A video of a dancing bird has become the latest YouTube sensation. Some people thought the bird's performance was faked, but for me, it is not surprising, given the sophisticated ability birds demonstrate for manipulating pitch and rhythm in their songs, that a bird shows the ability to keep time with music. Neuroscientists, including John Iversen of the Neurosciences Institute, have studied the dancing bird and confirm it is capable of extracting a beat from sound. What impressed me most about Snowball's performance is when he lifts his leg and gives it a little shake before bringing it down. As the investigators mention, it may be prompted by the pace being too fast to put his foot all the way down in time with the faster beat, but it piques my curiosity further. It appears Snowball is dividing the beat when he waves his foot, into two or three little waves, which if I am seeing it correctly, suggests birds are capable of division of the beat and perceiving and manipulating ...

Facilitating the Conversation

I was prompted by something Andrew Shafer of Reductive Labs said (on the FooCampers list, so I won't reproduce it here, since it was forwarded to me) about the quality of communication among software developers. He was talking about how communicating the overall design and intentions of the project is vital, so the developers are not left guessing about how the application will be used and what its architects think it should do. What is important is the existence of a conversation between the leaders of a project and the developers writing the code. This hits very close to home, because our farmfoody.or g project is essentially there to improve the flow of information between producers and consumers of food, to enable a conversation . It occurred to me the solution is to throw away the flash cards and bulleted design specifications and just facilitate the conversation. Why not use social networking tools for developers to communicate? (You can get a sense of another approach from ...
