Didn't know about this until now. I discovered this while I was investigating how a certain Web site still seemed to remember stuff about me even though I had cleared my cookies.
Quoted: Currently, only Mozilla-based browsers provide a working implementation of the DOM Storage specification. However, Internet Explorer does have a similar feature called "userData behavior" that allows you to persist data across multiple browser sessions.

DOM Storage is useful because no good browser-only methods exist for persisting reasonable amounts of data for any period of time. Browser cookies have limited capacity and provide no support for organizing persisted data, and other methods (such as Flash Local Storage) require an external plugin.- mohit | Shared With: Everyone - Sep 11 2007 | amazon, s3, storage, development
This new per request charge is very annoying -- especially in scenarios like the one I'm planning where you are using S3 for lots of small files.
Quoted: I had largely ignored the Amazon S3 pricing hike or decrease (depending on who you are) which included the addition of a per request charge. It really popped up again when I was recently talking to a new accelerator (just a few) + CDN customer recently.

Quoted: Because I am working on a widely distributed client application that can not contain our private S3 key, I have a web service on my own server set up that will create Query String Authentication URLS for use with S3. My service creates the URL, passes it back

The chart at the bottom of this article is helpful...it shows how long you can keep foods before they spoil. I was curious as I was cleaning out my fridge today:)
Quoted: The following charts provide general recommended storage times from date of purchase for various food products stored under optimum conditions. Storage generally is not recommended under conditions where no time is listed in the chart. For maximum shelf-life, consumers should always purchase fresh food and never temperature abuse food.

We think there may be an opportunity in flash memory. We may look at SanDisk in a future meeting.

This looks like a great addition to Amazon S3 and EC2 - they now have a way of creating simple tables with up to 256 attribute/value pairs. Support for GET, PUT, DELETE, and QUERY.
There are a number of things missing over a real relational database (or even an ISAM). S3 is a simple "blob" store - where each object get be atomically read and written. SimpleDB gives some simple query capability (for smaller data items - 1K max per attribute).
I also see no way to get ORDERBY functionality and, of course, no aggregate values (SUM, MAX, etc). Sometimes this can be overcome in the application layer, but it will make your application more complex than using a traditional database.
Most importantly, there are no JOIN's in this system. This will require the application to make multiple QUERYs to get the data needed to generate a view.
I found it very interesting that this document states that Amazon promotes developers running traditional databases in EC2. My understanding is that Amazon can arbitrarily wipe the state of any machine on EC2 - which would cause you to have to restore the database from some an S3 or external backup.
Maybe someone who is using EC2 for running a database server can chime in on how well that works for them.
