Single-purpose app to prevent .DS_Store creation under Mavericks
Asepsis updates have been officially released for Mavericks compatibility - http://asepsis.binaryage.com/
I've personally tested it, working like a charm!
The free app TinkerTool 5.0, which has many functions, can be used on Mavericks to disable creating .DS_Store files on network volumes, but I do not believe this has any effect on .DS_Store files on your local Mac.
