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 53: Nate Cavanaugh - New frontend features in Liferay 7
I met repeat guest Nate Cavanaugh, Liferay's Director of UI Engineering, at this year's Devcon and he answered all UI-based questions that we could quickly think about - specifically with regards to Liferay 7.
As we recorded this on site at Devcon, you'll hear more background noise than usual - Auphonic did their best to clean the recording, and they did a great job.
Here are some of the topics that we talked about:
- UI frameworks get out of style soon. Can I still use AngularJS?
- Do I have to throw everything away that I have invested already?
- The YUI story and what its discontinuation means for AlloyUI
- Will AUI be reimplemented on jQuery? Is jQuery part of Liferay 7? What about different versions of jQuery?
- metal.js
- Lexicon, UI-Language, User Interface Guidelines
- Artifacts and Implementation of Lexicon
- Bootstrap, Bootstrap components, Atlas, the bootstrap versions in Liferay 6.2 and the components of it that are available.
- What happens when Bootstrap 4 comes out?
- Single Page Application, SPA, SennaJS: Go without full page reloads, largely by default.
- New Theming Tools - You can also use new tools in Liferay 6.2 (AYOR though). No more
_diffs
folder, pure frontend packages, themelets. - What kind of themelets do we wish to have?
- We probably have forgotten something. Ask your questions in the comment section of this episode to be covered in future episodes.
