RL061 Caris Chan

It took me long enough to bring her on: She's followed Liferay's history for longer than some of the other founders: Caris Chan. And yes, that name means that she's Brian Chan's wife. During my last visit in Liferay HQ, I took the opportunity and asked her about her view on Liferay's history - about 15 years for the company and 20 years for the software project. Here are some of the topics that we talked about: The history of Liferay as a product: How and why Brian started Liferay, and the first offer to buy the product. Caris' role from history to the present Early expansion and how Caris' pessimism balances Brian's optimism How Open Source opens doors that you didn't know where there (Shoutout to Bala) The reason for a lack of an exit strategy among the owners - why Liferay stays privately held without venture capital 10% of Liferay's profits go to Liferay Foundation - as smart investments in the world How does a company that strives to stay private get into the acquisition business, acquiring two companies?

RL045 Bryan Ho on Design and Ray

I had a short meeting with Bryan Ho, Lead Graphic Designer at Liferay - With that role it's obvious that we're bridging the audio/visual gap again: A very visual topic in an audio only podcast. But if you're not driving while you listen to this podcast, you can click the links from the shownotes and browse through the archives. Apart from being the creator of the Radio Liferay Logo, Bryan is the creator of "Ray's intergalactiv adventures". You can check out this series at https://www.liferay.com/ray. We talked about The history of Ray:  He is an "old" mascot, has been around on the very old website Bryan started to get involved with Ray for a T-Shirt contest in 2010 and continued to draw him How Ray's intergalactic adventures were started (Shoutouts to Paul Hinz and Martin Yan) At Devcon Bryan  created a lot of variations on Ray "on demand". You can find several of them on the flickr stream from that event. Luckily, Bryan keeps Ray around, for example on community T-Shirts, even though the cartoon series is currently on hyades. And other things that the design team works on (Website, Events, improve overall visual appearance) Here's Ray listening to Radio Liferay:

RL062 David Nebinger

A conversation with David Nebinger, the number one contributor on the Liferay forums, about frequently asked questions. David's history with Liferay, reaching back to version 4.x Should I use an ext-plugin and what problem does it seem to solve? (TL;DR: No) 10:35 Should I make changes to the database? (TL;DR: No) But... I need to add a column to the built-in tables... Liferay's Expando API (Custom Fields) What changes to the database might do to your future upgrades The alternative to change data directly Fake Entities (a ServiceBuilder feature that was of good use in earlier versions but is now well superceded by just standard OSGi Declarative Services) Things Liferay won't say. Full article, well worth a read What Appserver should I use? How should I build my portlets? What database should I use? Why doesn't Liferay tell me how to size my cluster? Devcon 2019: David's upcoming presentation on "Programmatically loading your site with content" His interest in Headless features of Liferay His recommendation to come to the Unconference How to come up with the topics for David's blog articles, and what's in his queue Why should I use ServiceBuilder?

RL055 James Falkner on Change

In this episode I'm talking probably one last time to James Falkner about upcoming changes... James was the first guest on Radio Liferay (back in episode 1 - as well as others) and now - at least temporarily until episode 66 is published - will be the last. We're talking about upcoming changes, and sadly it looks like this will be his last appearance on this program.  Note: Currently the audio is still in post production, I'll publish it soon. Just subscribe to the Radio Liferay feed in your favorite podcatcher to get it delivered automatically. If you know the background of this story already, you'll understand that I think full shownotes for this episode are not really appropriate. However, here are a few references if you want to follow up on some of the details: Community Tummler git manpage generator Community Security Team Marketplace Events App (iOS, Android) Community Expedition Vanilla JS Climate of Antarctica James' video farewell note Stay tuned for further updates on what changes in community relations

RL054 Scott Nicklous and Neil Griffin on JSR 362 - Portlet 3.0

In this episode, recorded at Liferay's Devcon 2015 in Darmstadt/Germany, I'm talking to Scott Nicklous and Neil Griffin. Scott is the specification lead for JSR-362 - otherwise known as the Portlet Specification 3.0 - and Neil serves as Liferay's representative on the expert group. Here are some of the topics that we talked about: JSR 362 page with all the latest and current information (spec, prototype implementation and javadoc) The expert group JSR 286 portlets will run unchanged on JSR 362 (runtime and compiletime compatibility) My repeat favourite statement about frameworks in the web world. JSR 362 and its impact on UI, there's a Client-Side standard (on ECMA script) for the first time in the portlet spec The big question: When will it be done? (Some time 2016) Early Draft Review Spec available, ~80-90% of content is expected to be there (That's the statement from Devcon, in October 2015) Reference Implementation (to prove that the spec can be implemented) and TCK still missing (again, October 2015) Reference Implementation and TCK will be implemented under the Apache Pluto project, help required New Features include Bean-Portlet-Approach (portlet methods specified through Annotations in any Managed Bean), portlet.xml file no longer required if Annotations used specifies a JS API despite being a JSR, which covers traditionally only Java Dependency to JavaEE: Minimum is JavaEE 7, e.g. Servlet 3.1 etc. Portlet Spec is not part of the JavaEE, but extends some of its elements. CDI JSR 378: Portlet 3.0 bridge for JSF (where Neil is the spec lead), being built in parallel with JSR-362 Multiplatform Support, Websocket, Devices The E-Mail Archive of the specification process is public - contribution and comments are very welcome

RL053 Nate Cavanaugh - UI news 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.

RL052 Raymond Augé - Upgrading your 6.x plugins to 7.0

A continuation of last week's episode, Milen Dyankov stepped in as a co-host and helped me ask the right questions: Ray Augé answers all sorts of questions about the Modularization in Liferay 7 and what to do with your existing investment in Liferay Plugins - what to do with the plugins you already have, where you will have to re-learn and what you can, should or shouldn't continue to do.. 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: Portlets: If you're not interacting with Liferay, e.g. a pure JSR-286 portlet: No changes required JSF: Last kinks are worked out - test the more complex the JSF implementation is If you're using Liferay API: You'll have to resolve API changes - e.g. recompile and check if the API is still valid. Check these breaking changes - well documented, huh? And even better: The document is machine-readable and there will be migration tools (future episode planned) If the service is still in Liferay's core: No change needs to be made. If the service is now in a module: Check if the package was updated. Fix if necessary and if the migration tool didn't do it for you. Circumstances under which Liferay automatically "translates" WAR file into OSGi bundles - and the caveats Extensions to Liferay MVC portlet: Check for the nature of those changes The use of CDI - especially when the appserver's implementation/resources are utilized - still requires some work. Everybody who's doing really advanced stuff on sophisticated frameworks is welcome to try it out now and let us know now if there are any problems that remain How little of OSGi can I get away with? Hooks Many of the hooks - especially on services and models will continue to work, but won't have more power than in 6.2. They're prime candidates to be converted to an OSGi module as this will enable them to tap into a lot more extension points in Liferay 7. Struts Action Hooks probably need changes - while they still work, most of the underlying actions have been reimplemented without Struts \o/, so possible overloads in Struts actions won't be taken into account for the new implementation. (most likely: You need to convert to an MVC Command, injected as an OSGi module. There are samples available) Liferay 7 has a lot more extension points than prior versions. The documentation is being made available on dev.liferay.com - obviously this is still work in progress, but is scheduled to be there until release. How can IDE and other tools help identifying which extension points are in use? And how to make lots of friends within the Liferay Community Overriding Language Keys is quite simple - choose "global" or "per portlet" - those are the two available scopes that a translation can live in. For migration you might have to decide which scope your changes should go into. Encoding still is done in UTF-8 JSP-Hooks: The elephant in the room: Seems to be very popular, but always has aimed at the implementation rather than to an API. As drastic UI changes happened in Liferay, these implementation need to be implemented on the new infrastructure, leveraging new techniquest (e.g. Lexicon). Also, most of the functionality has been moved into modules - JSP-Hooks only affected the core jsps... New options: JSPs can be deployed as proper OSGi bundles. There's still danger because technically the implementation is unchanged compared to earlier versions New fragment modules enable you to override JSPs in any portlet - not only core ones. But you shouldn't limit yourself to JSP-overrides: There are more ways to change Liferay's UI, e.g. replace the render-phase of a portlet through a portlet filter. A new "dynamic include" API to inject extension points at very specific places - e.g. at those UIs commonly targetted by overrides. (let us know which are missing) Application Adapters Ext Ext Plugins work just like before (in core). But most likely, the implementation has changed anyway, so that you need to make sure your code is still valid for the current version - but that's what you expected when you started writing that ext anyways, right? Of course you'll have to check if your changes still are contained in Liferay core. If they're extracted to a module, ext won't be yours any more (for these changes) Ideally, ext will be the easiest plugin, as it probably will be a lot smaller than before. We haven't covered all possible questions and are planning a "Listener Questions" episode. Please ask your questions in the comments to the blog article for this episode to get them answered in the next episode with Ray.

RL060 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.

RL051 Raymond Augé - Motivation for Modularization

Another Devcon "private" session - I missed his presentations, but got the summary right when he was done: Ray Augé took the time to answer all sorts of questions about the Modularization in Liferay 7. In fact, he answered so many questions that we made it a 2-episode recording. This week it's about the motivation for modularization: What problem does it solve? Next week will be more technical, telling you about the implications of the updated architecture to your code. As we recorded this on site at Devcon, you'll hear more background noise than usual - As 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: OSGi in Liferay 6.2 vs Liferay 7.0 Modularization of Liferay 7.0 Surprisingly (not!), modularization is not yet fully done, but it came a lot further than expected initially How much do you have to re-learn to build plugins for Liferay 7 James: Community Roadmap Talk from Devcon (note: Ray also had several presentations at Devcon, you'll find his recordings there as well) Now everybody should be able to work the same way: Internally in Liferay's core as well as externally, in the plugins. Ant vs Maven vs others? What's the story with Liferay's supported Build environments? More energy will go into build tools other than the SDK Of course we cover a release date :) I'm getting a very rough one from Ray :)

RL050 Pimp My Scriptengine with Jens Bruhn

Wow, 50 episodes already. At this year's Devcon I spoke with Jens Bruhn. He's Software Architect at Prodyna AG, a Liferay Partner and the author of Nabucco Script Center, a Liferay App available on the Marketplace. He also convened the "Pimp my Scripting Engine" workshop at Liferay's Devcon 2015, which I missed. But this only provided a perfect reason and excuse to speak to him. As we recorded this on site at Devcon, you'll hear more background noise than usual - As usual, Auphonic did their best to clean the recording, and they did a great job. For the visuals, please see the screenshots in this article as well as the plugin's homepage. Here are some of the topics that we talked about: The Elevator Pitch: What's Nabucco Script Center? Scripting in Liferay: The native script console, its use and its shortcomings (solved in NSC) a short demo of Script Center. It makes sense to check the screenshots alongside, or even install the plugin: various scripts (for example: Reset Terms of Use Acceptance) and instruct content editors to execute this script whenever they change the actual Terms of Use Article) Automatically run scripts (again, same example, this time executed automatically on every update of the article) - comparable to a model listener plugin for Liferay's Service Builder Scheduled Script execution. And basic sanity checks: When deactivating user accounts, you might want to have a few exceptions to your rules, e.g. in order to not lock out administrators that can help you gaining back control, but are not logging in every day. Prodyna has scripts available on the app's homepage - e.g. What happened during the last 24 hours? How many users logged in yesterday? Basic data on usage on the start page ("heartbeat"). Warn authors in time before review dates of their content. Assign permissions based on categorization of content. Fine grained permissions can be granted per script, e.g. just because you're able to upload/edit a script you might not be able to execute it - and vice versa. Feadback required - is this useful and what else is needed to make it more useful? How to develop without and with Script Center - where can it help you in your development process. Here are the slides that we talk about: Best Practices when implementing features in scripts: It's easy to accidentally make mistakes - there should be some basic safeguards. Script Center offers a third option to two customization approaches mentioned my earlier blog article

Today, Tomáš Polešovský starts of by talking about Liferay's security team and -procedures as well as his work within that team. Tom has already been a guest on Radio Liferay's ancient episode 9 Here are some of the topics that we talked about: The glorious glamorous days one has on the security team (consisting mostly of email, tickets, pullrequests) Different ways to make Liferay more secure Gathering feedback from community and customers Monitoring Liferay Forums and full disclosure mailing lists (also about the various libraries that are used in Liferay) Scan source code for problems Liferay cooperates with external security researchers for penetration testing Customers perform external audits as well. An example of an actual audit report: 49 very alarming false positives vs. 1 real cornercase The security issue fixing process The first security episode with Sam Kong Link to community security update page.

This is my conversation with Stian Sigvartsen, winner of the Marketplace App contest with his Social Apps Proxy (Link) and well known member of the UK Liferay usergroup, working in Devon and quite a lot with Liferay. Our paths cross quite often, but we finally found some time to talk about Stian's award winning app which basically takes all the boring stuff out of OAuth integrations into Liferay He did a great job of explaining the background and solution in audio. Here's what we talked about: Social Apps Proxy enables you to integrate content from other social networks into your portal. It's working through OAuth, basically taking over all of the dirty work of authentication, leaving the actual integration works for the implementor Stian's sample app on github (Link): Getting twitter mentions with 10 lines of code What problem does OAuth solve? Comparing OAuth with a Valet Key. Linking Liferay's identity to twitter's (in this sample) How the social apps proxy works: An application just uses it as HTTP proxy, does not care about identity and is happy to get the identity automagically taken care of Social Apps Proxy on Marketplace Supported Versions of Liferay 6.1 to 6.2 and OAuth 1.0a to 2 to be extended Microservices All Code is to be open sourced soon, contributors are welcome.

Brett had a presentation on >DevOps Best Practices with Liferay, Logstash, Kibana, Elasticsearch, and New Relic at Devcon (among other symposiums and events). If you missed it or just want the audio summary (both were my motivations to talk to him), we're talking about his experience, using one of the projects (an unnamed one) as an example. This is a short conversation as we didn't have a lot of time in between different appointments, but we've committed to making this a series of episodes on similar topics - and more in depth.
