Radio Liferay Episode 60: Performance and Permissions with Preston Crary
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.

Radio Liferay Episode 56: Jorge Ferrer
Today I'm welcoming a repeat guest, Jorge Ferrer, Liferay's VP of Engineering. I've had the great opportunity to ask him a lot of questions that provide deep insight into what's running behind the scenes in the engineering team. We didn't have enough time, so this is part 1 of our conversation, to be continued in episode 58. I need to squeeze in the (already recorded) episode that contains more information about the Javadoc Contest (please participate). Those episode links will work once the two episodes are public)
Jorge gives an update on various internal as well as external topics. I'm also teasing him a bit, and hope that this episode will be as insightful for you as it was for me.
We're talking about these (and more) topics
- the engineering team passed the 150 people mark, distributed world wide.
- Communication in a team that's distributed through the world, tools
- Some nasty german guy recently took Jorge's #3 contributor place on the public forums
- Participation & Contribution: Check https://dev.liferay.com/participate.
- What happens to pullrequests to the Liferay repository? Should you rather direct to the component lead?
- Coding Standards, Design Patterns and how many you want to use in a single project
- Pullrequests and who's working on them.
- The experience of upgrading the architecture to OSGi in Liferay 7
- Jorge's Architecture Blog Article(s)
- News about Developer Network: Many new project documented there
- We're closing (for today) with a short fun quiz about new frontend tools introduced with Liferay 7, in which Jorge earns his street credibility.
- stay tuned for the continuation of this episode, most likely in episode 58.
