Sun has just announced that they will begin close-sourcing MySQL. For years, I’ve avoided MySQL due to a mixture of paranoia (I’ve had extremely bad experiences with MyISAM-backed data stores) and disdain for their shoddy standards compliance (which has bitten me before in nontrivial ways). Now I can also avoid them for not being open-source.
My standardization on PostgreSQL for this website feels more rational by the minute.
Update: The originally linked article wasn’t quite correct. MySQL AB’s CEO explains that they will not be making the MySQL core closed-source; merely new, enterprise-specific features. You can read his whole statement for more information. This position is more reasonable, and is similar to the relationship ElephantDB has with PostgreSQL.
