>>14410101salami slicing is probably the biggest one in terms of getting most unique (or should i say "unique") publications out of the least amount of work. That and re-using parts of the same results for different articles.
Aside from that, try to collaborate with as many people as possible, because it gets your name on their paper even though you yourself have to do just a small bit of the total work needed for that publication - do not do solo articles.
Also, you can write short articles ("letters"), it uses results more sparingly than articles of normal length. Thats all I can come up with on the fly
