This looks potentially interesting. I use R for analysis and plotting graphs as a rule but this might be handy for quick plots.

Useful webapp for testing website layouts at different screen sizes.

Interesting free service which will send you a reminder email after a given interval when you include [time-interval]@followupthen.com as a recipient on an email.

Marks revisions by each author in real-time, like SubEthaEdit.

Beta SimpleDB service from Amazon, integrating with their S3 storage service.

A nice guide to using the Google Chart API (something I had never heard of before).

Good comparison of some of the free online file storage services.

Very slick and capable online photo editor. Lets you edit and then send files to flickr.

Looks more than a little like Backpack.
