Beerware no-warrany and no-patents
Why another license? Beerware license is good but it lacks both no-warrany and no-patent clauses.
No-warranty might be important if you live or operate in a state or country which imposes warranties upon you by default.
No-patents is purely ideological clause that, in theory, should make your work not usable by patent trolls and hostile patent claimers (like Oracle, Microsoft, etc.)
This is an open-source, no fuss, attribution-only kind of license which allows commercial use and distribution of the code (or whatever you impose the license on).
