What's a good cloud based file storage platform to use with Silverlight?

I'm working on a Silverlight app that would allow a user to upload a few gigs of files to a hypothetical cloud based file store, then allow the user to view some data about those files later (more functionality than a file store). Ideally I'd like to use a free, per-user store such as SkyDrive but I can't seem to find an API for that se...

Storing very large integers in MySQL

I need to store a very large number (tens of millions) of 512-bit SHA-2 hashes in a MySQL table. To save space, I'd like to store them in binary form, rather than a string a hex digits.

VARCHARS: 2, 4, 8, 16, etc.? Or 1, 3, 7, 15, etc.?

I see VARCHAR(255) being used all the time instead of VARCHAR(256), but I also see VARCHAR(16) being used instead of VARCHAR(15). This seems inconsistent to me. If an extra byte is being used to store the VARCHAR's length, shouldn't this rule also apply to the smaller lengths like 2, 4, 8 to be 1, 3, 7, instead? Or am I totally missing ...
