Technology has always been used as a memory aid, of course, but in past millenia, scratching on a clay tablet, writing with a fountain pen, and snapping a digital photo have all required an act of will. Humans had to choose what they would remember.

Now, in an age of ever-cheaper storage, the data committed to machine memory requires an act of will to delete. Storage is now so cheap, in fact, that it requires more effort to cull an e-mail inbox or photo gallery than it does to simply hold on to everything.

To get back to a default state of forgetfulness, Mayer-Schönberger offers an intriguing proposal: find simple ways to give data an expiration date.

Over time, though, my initially rosy feelings towards ORMs have begun to sour. I gradually realised I was spending a disproportionate amount of time trying to coax the ORM into doing my bidding - and when I succeeded, the results were often ugly, slow and needlessly opaque. Analysing the performance of some of the more complicated portions of my data access layer was often painful, and I spent cumulative hours poring over generated SQL, trying to figure out what the ORM was doing and why. Usually, improving performance involved side-stepping the ORM altogether. Recently, a particularly gnarly performance issue prompted me to ditch the ORM from a project altogether, with surprisingly pleasant results.

A Redundant Array of Independent Drives (RAID) is a method of grouping multiple drives together to improve performance or fault tolerance. Because m1.large and m1.xlarge instances have multiple ephemeral stores, you can now use RAID with these instance types.

YoutubeFS enables you to browse your favorite Youtube videos locally on your desktop without going to the youtube website. Just create a youtube account and add videos to your playlists, favorites list or subscribe to different channels. YoutubeFS then enables you to automatically load these videos to a local folder on your desktop. You can then view these videos (using a browser) as if they are local files.

Unprecedented data volumes are driving businesses to look at alternatives to the traditional relational database technology that has served us well for over thirty years.

Collectively, these alternatives have become known as “NoSQL databases.”

Brief overview of non-relational databases follows.

1. CRUD is crud. The fundamental activities of Create, Read, Update and Delete are fundamentally wrong-headed. Updates to data should never be allowed, because they destroy information and Deletes should never be allowed for the same reason. When data changes the database should just add another record and note (by any mechanism that works) the previous value for that record. If the database gets too large then data should be archived from it. The right set of activities is thus CRA, Create, Read, Archive.

This is also known in the vernacular as "second save loses". It may sound too harsh, but it is much better than "first save loses and user isn't notified", which is what you get if you have no currency checking at all. And it's also much more web friendly that your old desktop app (which uses an approach that is technically called "pessimistic locking").

TV Tokyo visited Gome, a major retail chain in China, where CBHD discs and players were flying off the shelf, while Blu-Ray players and discs languished. They also visited a factory for one of the largest CBHD manufacturers. Sources in these companies tell TV Tokyo that, in the China market, CBHD already constitutes some 30 percent of all disc players sold, while Blu-Ray accounts for 10 percent, similar to its penetration in the USA. DVD is responsible for the remaining 60 percent.
