Does anyone have some code which interprets Surface Weather Stations
reports (formally termed 'FM 12–XIV SYNOP' reports) ? I've tried the

On the Python Dev mailing list, there is a discussion going on about the
stability of the hash function for strings.
How many people rely on hash(some_string) being stable across Python
versions? Does anyone have code that will be broken if the string hashing
algorithm changes?

OpenOffice (now LibreOffice, btw.) is not implemented in Java, if that's
