Welcome to Radio Liferay, a peek into what is going on in Liferay from the people doing it themselves.
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 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)
- 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 24: Zsolt Balogh, LESA
This is another episode recorded at the European Symposium 2012 in Wiesbaden. Zsolt Balogh, head of Liferay's Support for the EMEA reason talks about the pain points that led to developing a custom issuetracker and support management system. Enterprise customers know what he's talking about: Liferay is using LESA to handle support issues, fix and escalate them. To follow the visual part of the presentation, please go to the symposium's download page
Zsolt starts by laying out why Jira was fine for a single project (and it continues to be in use at issues.liferay.com), but not so much for the way we're supporting the enterprise customers.
After introducing the problem space, he's going through implementation timeline, migration, features and requirements, as well as later evolution of the system (naturally, LESA is still being actively developed and extended). Also, there are lots of metrics and how they are helping to improve service or efficiency growing the team.
You'll learn how Liferay's support teams were organized internally over the time and where we're heading to. At Liferay, we're not eating our own dogfood, we're rather drinking our own champagne. Where we don't do this now, we're planning to do so very soon. LESA is part of the activity to move a lot of functionality from 3rd party software into Liferay (or to integrate that software into the portal).
