An episode on the "Per" things: Performance and Permissions. I spoke to Preston Crary, who amazingly was not mad at me for losing an earlier recording. We're talking about these (and more) topics  		We open with the attention to detail that's required for working on performance tuning and some short conversation about this topic. 		Sadly, there's not often a single silver bullet, but many areas of dust.  Sometimes the fastest code is not the most optimal 		Continuing with Preston's work on Permissions: 		ResourceBlock is deprecated, and there's an easy migration path  				an example upgrade path for bookmarks   		The usecase for Resources, ResourcePermission, and ResourceBlocks (as they're not at all visible on the UI) 		Preston's way through Liferay from Support to working on the topics that he's now working on 		The new API for Permissions - and the documentation is also done already (as of me writing this article, not yet published, but available on github - should be a matter of days or hours)		 				And an example: The implementation of this API in Journal 				more documentation on registering and checking permissions   		Should you implement your own permission system? (and how the answer to this question might change in 7.1) 		Upgrades are being performance tuned. I smell a future episode coming up. Paging the team that is working on this area 		The remarkable memory savings that refactoring the UserBag introduced 		What happend during login 		Passwords are PBKDF2WithHmacSHA1/160/128000 hashed, a deliberately expensive password hashing algorithm.  LPS-75747 and an update to my hardball question: Document Library's default.xml is still in core, can't be updated through a module, just through an ext.
