I felt the need to contribute somewhere in the open source department. My first move was to start a provider for Euss enabling support for using SimpleDB as storage. Store your objects in the cloud! It’s buggy and the query language is only partially implemented. But anyway. It does work.

It has the immensely creative name “SimpleDB for Euss”. You can find the source and upcoming releases on codeplex.

I present to You, the first alpha release of RawPreview. For now it's only a preview handler for Windows Vista allowing preview of different raw image formats in the preview pane. I'm using dcraw to extract the embedded thumbnail. It currently only registers for *.pef, *.dng, *.nef.

For the future:

• Support thumbnail creation on Vista and XP
• Be able to edit the file-types it's registered for in some kind of GUI
• Show exif information in the preview on Vista
