The Apache Hadoop Core is an open source platform enabling developers to write and run applications across clusters of commodity computers and process vast amounts of data. As a primary investor and developer of Hadoop, today Yahoo released their own tested distribution of the code that powers their search engines, ad systems and webmail services. There is a growing move toward design patterns that leverage the parallelism inherent in distributed systems such as Hadoop and Google's MapReduce. Applications can be developed on single servers then deployed on massively distributed cloud infrastructure without knowing the details of such distribution. Once these applications are deployed they can act as their own service provider to other systems. Indeed we see that scenario with Amazon's EC2 (with native Hadoop support), IBM's Blue Cloud Initiative and Google today. This type of database is not a relational engine like Oracle or SQL Server. Hadoop enables large scale data mining for useful applications such as fraud detection and rich media indexing. I think this release is significant because it allows developers to take advantage of all the work put in to improve Hadoop over the years. Yahoo's change log file has over 8,400 lines and contains a wealth of knowledge gained by real production experience. Can Yahoo gain cloud credibility by giving it away? I think so; it gives everyone a living benchmark.
The ingredient digital ink for Kindle, E Ink, is working with Plastic Logic to develop a reading tablet to display books, newspapers and magazines. Many content owners in the industry view Amazon's middle-man role as unfavorable in that they set the pricing and the layout of content for the Kindle. Since the early 2000's, firms producing the reflective layers of the nanostructured films of titanium dioxide that create the solid white background have come down the learning curve. This process improves reflectivity and contrast while eliminating the need for backlighting. Innovations in bistable voltage have optimized power management. Newer displays, for example, can operate on very low voltage that only charges when the image is updating. Amazon commercialized this type of technology in high volume with the Kindle. Publishers complain that the Kindle doesn't allow for advertising and it is a poor substitute for the feel of pages - they would. Warren Buffet said recently he would not buy any Newspaper publishing company "at any price" because of the business model erosion. I see potential consumer confusion with the proliferation of these devices, especially if the industry takes different directions from Amazon, Apple, Sony, Gannett, NY Times and other publishers struggling to re-invent themselves.
