Radio Liferay - the podcast about Liferay: The people, the project, the product and the company

A repeat guest - today I've talked to one member of my team, Bryan Cheung. Bryan was start of my welcome committee when I started working for Liferay in 2010, and that's where we start the conversation.

David Gomez is part of Liferay's Developer Relations Team, and we took some time to talk about the upcoming /dev/24 livestream of developers and other users of Liferay DXP and Liferay Portal with a technical background.

Yasuyuki, short Yasu, is Supportability Engineer at Liferay. He's working out of Japan for ~8 years now, and in that time has started an interesting side project that you might be interested in. Well - I was interested, so I asked him for some time and we talked about it: Damascus.

For this episode of Radio Liferay, I've talked with Bryce Osterhaus, Frontend Developer at Liferay for ~ 6 years. With his experience, he's a perfect complement to me: While he feels at home in the browser, client side, I'm comfortable on the backend, away from all of the messy frontend stuff - prepare for some naïve questions coming his way.

We spoke about a design decision that has been made in some internal projects: His team has built a UI that does not utilize Liferay's page/site infrastructure. It's rather an application that utilizes some of the infrastructure but not what's typically used to compose frontend applications on a portal.

Or, in the rage of the day, you could say: "Headless". ;)

A while ago I sat down with Ryan Schuhler. He's Associate Program Manager at Liferay, which is a fancy name for Webteam Lead, and we talked about "dogfooding" Liferay DXP to build liferay.com - which features are used, how the site evolved and what is fed back into the product.

Oops - in times of fast news like this, I sat on the recording for a while. Unacceptable, but as almost nobody is commuting in April/May 2020, it's questionable if you'd have put it on during your commute anyway... Happy 10th Birthray to Zsolt and me and several others (listen to the episode if you want to know what that means)

This is a quite non-technical episode, just two people remembering the "good old times": Don't expect to learn anything new about the product(s) - instead you'll hear about how we got from "there" to "here" in the past 10 years.

An episode that was recorded together with episode 62, but got a bit lost (well, I admit - it was just sitting on my disk). But here we are: David shares four of his favorite horror stories - those that tought him what he never wants to see again. Hopefully it's useful so that you learn from it before experiencing those stories yourself.

For this episode I spoke with Andrew Jardine, Community Contributor Award winner for 7 years in a row about his history with Liferay, the community, how to improve it and, of course, his new passion project, https://masteringliferay.com/ We've recorded this episode during Devcon 2019, but I've been keeping it back for a bit, to give Andrew a bit more time to produce more content for the site that we mainly talk about. Check it out - prepare to be amazed. (More notes and links available in HTML version of this paragraph and in the blogpost linked to the episode)

A conversation with David Nebinger, the number one contributor on the Liferay forums, about frequently asked questions.

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.

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.

Yay, another episode, and maybe in time to sweeten your trip to Devcon in Amsterdam. I spoke to Kristoffer Onias and Victor Ware. Both work on testing Liferay with different areas of interest. You'll hear quite a bit about what Liferay does internally on testing.

I actually talked to them quite a while ago, and the episode has been sitting on my disk since then.The numbers that you hear may no longer be accurate, but the overall information definitely is. Sorry for keeping it a secret for so long (there's an even longer kept secret... up next...)

Two episodes (or an eternity) ago, I spoke to Jorge Ferrer, Liferay's VP of Engineering. We didn't have enough time to finish the conversation, so we continued a while after - and then I buried the recording /o. Anyway, apart from it being still from "before the release of the current version", it's still relevant stuff, I feel bad about missing to post it. Check for yourself - here it finally is.

Today I'm welcoming a repeat guest and a new one: Jim Hinkey (of episode 21 fame) and Cody Hoag - both from Liferay's documentation and knowledge management team. This episode has unfortunately suffered from various disturbances in the space-time-continuum: I had it sitting on my disk for quite a while. The Javadoc Contest that we've "started" in this episode was actually published/announced in the meantime and unfortunately ended recently. Congratulations to Sébastien and Marcellus. However, not to render the call for action in this episode useless, let's start another one soon - there can't be enough Javadoc, and I admit that we have still plenty of opportunities to write new documentation left for you. Please subscribe to the comments on Cody's winner's announcements to see the update - I'll also mention it on a Radio Liferay episode once it's been restarted. But I'll also put a word in for you if you already write the javadoc now.

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).

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.

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.

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.

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.

A short Inbetweenisode on the release of 6.2 CE GA3 with repeat guest and Community Manager James Falkner. During Devcon James promised (http://youtu.be/U46tCHFeutM?t=34m27s) the release for the 15. January - while I stated that this release date was wishful thinking. Now we actually hit the promised release date for the first time known to both of us. Enough reason to get together and talk about the underlying cause and intents.

Another Devcon conversation - make sure not to miss it next year. I grabbed Chema Balsas, Software Engineer at Liferay Spain, and Emil Öberg, Consultant at Monator Technologies, a Liferay Partner Company in Sweden. This is a three-way conversation with Chema Balsas and Emil Öberg that we had during Liferay's Devcon 2014. Chema had a Theme-Workshop (sorry, no recording) and Emil a presentation on Rapid Frontend Development, so it made sense to talk to both of them as their experience overlaps. Speaking of experience: Chema is a Software Engineer in Liferay Spain, Emil is a Consultant at Monator Technologies, a Liferay Partner Company in Sweden.

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.

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

I'm talking with Brett Swaim, Principal Consultant at Liferay US, on application performance monitoring, horror stories and things to avoid. Brett is dealing with a lot of customers. He's one of Liferay's go-to resources for performance tuning and monitoring. 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.

At Devcon, I took the opportunity to meet several people - stay tuned for several more episodes during the rest of this year. For this episode, I spoke with Zsigmond Rab. Zsigmond is Lead Engineer, Technical Support & Trainer at Liferay Hungary. This is a short and informal tongue-in-cheek talk about support-related issues.

Another first: This week's guest Máté Thurzó presents a brief 37000ft overview over Staging. Yes, this is literally 37000ft - we both were lucky to be invited to the North America Symposium 2014 and had the same flight back. Yes, this episode has been recorded 11277m over the atlantic ocean on the flight from Boston to Frankfurt, and it's also a first time that you see me use imperial units voluntarily.

\o/ Radio Liferay is back. A while ago I talked with Juan Fernandez and Ivica Čardić about an exciting project they're collaborating on: Liferay Cloud Services. "What's this?" you ask? Well, good that you're asking, because here's the explanation. It's all about helping you monitor the health of your Liferay Installation, keeping an eye on the installed fixpacks (if you're using EE) or showing you some monitoring information that the server provides and you'd otherwise risk not to see.

(The episode is prefixed with a PSA for all Radio Liferay Listeners: The CfP for Devcon2014 is still open until 22. Aug 2014) and if you intend to come to the unconference on 4. Nov., make sure to register early: We have limited space and already predict that we'll sell out the unconference - there are enough seats available for the regular DevCon)

I talked with Alberto Chaparro. Alberto works for Liferay as a support engineer on the spanish team. This conversation follows up on something that Iliyan mentioned in episode 37: The migration tool that will help you upgrade your portlet from 6.1 to 6.2. We're talking during the end of the symposium, so the background noise that you hear are people that are starting to break down the staff room.

At Devcon 2013 I've met with Greg Amerson, main Author/Team Lead for the Eclipse-based tooling (Liferay IDE & DevStudio) and David Truong, one of the very early employees of Liferay, Product Manager for Platform an Tooling. The topics we covered were all around Developer Tooling. There's a bit of background noise as we were recording this session in the break area of the conference. We had to limit ourselves to the time when some sessions were on, in order to find the quietest possible environment.

At Devcon 2013 I met with Miguel Pastor and Ray Auge, both Engineers and Core Developers at Liferay. They both have been involved in the latest modularization efforts, resulting in OSGi being now on the Feature List for Liferay 6.2.

We recorded this session in the break area of the conference, during one of the sessions in order to find some quiet time. Unfortunately, as you'll hear in this recording, we picked the time when Lunch was prepared, so the catering staff is setting up stacks of plates, heaps of cutlery and other noisy stuff. This episode might be the one with the most background noise we ever had on this podcast, but after all, it's in the background and I hope it doesn't distract too much. Be assured, the lunch was really nice.

It's my return guest show time - here's another one. However, you've unfortunately never heard my first recording with Juan Gonzalez, back when we did it. This was due to a glitch that I'm really sorry for. Juan holds the Community Contributor Award 2012 and has since joined the spanish office of Liferay, working mainly in support and in the Liferay Faces team. As we missed doing so in the recording - we'd like to have a shout out to all the support staff in/for Liferay. These are the guys that keep the system running and the customers happy, but rarely receive some of the glamour of standing in the spotlight.

I took some time to speak to Jorge Ferrer, Liferay's VP of Engineering about all things Engineering and Development in Liferay. This time I'm not starting with butchering names, but positions. Jorge is one of the very early contributors to Liferay, started as community member and got hired, started the spanish office. After an episode "on the dark side", being the GM for Spain, he's back in engineering. We're talking about his responsibilities within the project, the company, and more.

As a preview for AlloyUI was just released (together with the new website) I took the opportunity to have another episode about the UI layer. Luckily two members of the core team, Eduardo Lundgren (with Liferay since 2007/8) and Zeno Rocha (Sep 2012) volunteered. (Eduardo was mentioned already in episode 3 with Nate Cavanaugh, Zeno has joined Liferay since then. Both of them are members of the brazilian team.)

We start with their history and

  • Zeno's project jquery boilerplate. He's also one of the founders of the Brazil JS foundation
  • Rosetta Stone, no longer hidden but very prominent on the website, comparing jQuery, YUI, AlloyUI
  • The traumatic transition time in 2010 between Liferay 5.2 and 6.0, when AlloyUI replaced jQuery
  • How Zeno got assimilated into Liferay
  • The new website for AlloyUI with Tutorials, Examples and Documentation (alloyui.com)
  • What's new in AlloyUI 2.0, when will it come into Liferay?
  • Feedback from the community (portuguese video on youtube)
  • Can I run different versions of YUI on the same site/page (as I can with jQuery within YUI with the help of YQuery)?
  • who else is using AlloyUI or contributing to it?
  • Zeno will be speaking at Jax 2013
  • Honorable mention of the library that YUI is unofficially built on top of.
  • TaglibGenerator: A tool to generate taglibs and integrate them with Javascript/AlloyUI
  • Integration of taglibs into Liferay IDE/Developer Studio (Link to Greg's Episode)
  • AlloyUI on twitter and stackoverflow

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).

New year's resolution: Publish more podcast episodes. Let's start - Happy New Year, wishing you all the best for 2013...

This is a solo episode with yours truly. I had a lot of fun preparing and presenting this session, "Well Hidden Features", at the european symposium 2012 in Wiesbaden/Germany, as well as in Milano. They both built upon earlier presentations at the nordic and french symposiums and have been used as inspirations for other presentations at the north american as well as the spanish symposium. So, if you were at any of these symposiums, there's a good chance that you've heard some of the content.

Also, if you're working with Liferay for some time, there's another good chance for you to know some of the tipps&tricks already. As I mention at the beginning of the recording: This all is trivial knowledge - but in order to be trivial knowledge, it first has to be known - and I hope there's something in it even for the more experienced among you.

View Details

Yes, I know. I didn't keep my previous promise to quickly follow up with the next episode. Thus, I'm not promising again, only revealing that I'm planning to be quicker in future.

podcast-logoThis is another episode recorded at the previous Liferay Retreat. I sat together with Samuel Kong, GM of the chinese office and member of Liferay's security team.

As I've been carrying this recording around for quite some while, note that there have been some changes during the last year. First and foremost, we have a new community security team, which was not around at the time of the recording. I'm planning to talk to someone from that team soon (consider yourself warned if you're on that team)

Some of the topics you'll find in this episode

How to file a security issue - thankfully he is consistent with what Cynthia and Michael have reported: go to issues.liferay.com, file your issue under the component "security", optionally with private visibility. If you've already done so, please try if your issue is reproducible in the latest available version - your issue might already have been reported and fixed. OWASP (The Open Webapplication security project) site is a good resource for learning about security in Webapplications in general, independent of Liferay. The three tools that Liferay has built-in, helping you to prevent security issues: Redirects: Some Properties, configuring the list of domain names and IPs, that Liferay is allowed to redirect to CSRF: Auth-Token XSS: The various escape-methods in com.liferay.portal.kernel.util.HtmlUtil - There are so many because the correct escaping depends on the context for which one escapes some HTML-Text. Also, the AlloyUI Taglibs help a lot when you're displaying user-content in forms. And also: The "escapedModel" that you can get from ServiceBuilder. Bonus: SqlInjection and its prevention through ServiceBuilder. When to escape HTML text in order to be most flexible. Sidenote: A call to extract and read the full portal.properties: A long, boring and interesting read. Oh, and the dtds for xml files

My apologies for the long break in publishing the episodes - I got distracted with a lot of work and once there is an interruption of a habit, you probably know how hard it is to get back into it. I hope to be on track again now and will publish the archive of already recorded episodes soon - and produce more of them.

This is another episode recorded at the previous Liferay Retreat. I sat together with Jim Hinkey, Knowledge Engineer and part of Liferay's knowledgement and documentation team, since March 2011. He took over ownership of the developer's guide and is the guy to bring back javadoc to Liferay (more about this and how/why Liferay once lost its javadoc at the end of this episode)

We talked about

How Jim found Liferay Life in Raleigh/NC One of his biggest chokes, the (re)creation of javadocs for Liferay The process that Javadoc now has to go through in order to get into the product and other topics

As I managed to get short hold of Brian Chan, I had the opportunity to ask two more quick questions - one about the day when Liferay lost all of its javadoc and one sneaky question about consistency with the example of ThemeDisplay. If you - like me - always wondered where this name came from, you'll have to listen to this episode

This is another celebrity show. I sat together with one of the well known faces of Liferay, giving a voice to it: You might know Bruno Farache better as his Alter Ego, Bruno Admin. If you ever installed Liferay CE, you probably know at least his portrait image which is the administrator's face greeting you on the default homepage and the one that you impersonate in order to make your first administrative steps.

We talked about

  • Bruno started 2007 with a Liferay Training in L.A.
  • founded the office as General Manager in Recife, Brazil in 2009
  • his experience with dressing up in the L.A. office
  • starting at Liferay (with the office rented from a church) meant that Bruno could tell his mother that he went to church every day
  • how he became Bruno Admin, seemingly taking the role from Julio, and what this means for attending a gym
  • Instead of handing out autographs, he got his own "flair", a pin that was handed out at the annual retreat for everybody who knew the password. Check out how much of the password he knows himself ;-)
  • The setup and responsibilities of the brazilian office and what he does in the time he's not "generally managing"
  • His responsibilities in Liferay Sync and the mobile story for the iOS and Android version (some brags about my personal pet-peeve, Linux support for Sync ;-) )
  • What my previous company had in common with Liferay (hint: Name duplication - or triplication)

View Details

In this episode I spoke with Juan Fernandez, starting with an embarrassing nonpronouciation of his family name. Juan is a Liferay core engineer in the spanish office, working mainly in the WCM parts of Liferay, also doing training.

We talked about

  • how Juan started with the task to integrate Liferay with Pentaho, becoming a community member and later joining the spanish office
  • How Consulting findings are fed back into the product and what Juan did for the internationalization and localization of content in 6.1, default data for structures, related content, etc. (lots of new features for version 6.1 here)
  • Juan's demo at the european symposium and what he did when he created a basic application within the WCM system
  • If you have already implemented new custom Assets you don't need to do anything to get "related assets" functionality
  • the spanish community, contributing features, plugins or other add ons, taking the examples of Jack Rider of xmlportletfactory fame, Aritz Galdos of Lifedroid, Juan Gonzalez (who contributed preview features for the document library)
  • the french community, e.g. Leo Pratlong, who did some translations. (Juan also speaks french and helps out in the french community)
  • ...and other topic

(I think I finally learnt how to pronounce the "z" in spanish names - challenge me when you meet me next time)

I finally spoke to Mike Young, founder, CTO and employee number 2. Unfortunately Mike had to leave early after last year's european symposium, so there I just got "the Brians" instead of the whole founder circle. This completes "the founders", though with Mike I'm more on the technical side. However. For those interested in the company history, there's still some things in there.

As you'll see and hear, Mike is the project lead for Liferay Sync which has just been released this week (1. February 2012) - check it out or listen to the earlier episodes where it was mentioned. (11 and 13)

Please refer to the Sync product home page or James' blog post announcing sync in order to see updates and current information on market positioning and licensing, which was not finalized when we spoke last December - so we didn't cover those topics then.

We talked about

  • how Mike first met Brian Chan
  • You might remember that Brian suggested Mike that he had to use EJB for his wedding website - here's the story behind that, and how it got him involved with Brian and Liferay in the end.
  • The parts of Liferay's code that Mike was involved in - starting with "everyone did everything"
  • Liferay Sync, OpenSocial and WSRP being the current areas of work
  • With Mike I finally found the project lead, responsible for lobbying for a Linux client for Sync and was able to rant on. He delivered a nice and understandable reasoning. Even though this means I'll have to wait, I guess I won't rant any more ;-)
  • The mentioned "not yet" released Sync product has actually been released this week
  • Mike is the initial implementor of the OpenSocial implementation in 2009 or 2010, but now handed it over to Dennis
  • I know Mike best for his involvement with WSRP, "Web Services for Remote Portlets" - we talk about what it is and what it takes to make this really compatible with other portals. There are quite some interpretations of this standard (and not only this) that need to be validated in the respective environments.
  • The aspects that eat into performance when you have two portals involved in answering your request - and what the implementors on both side can do to mitigate the drawbacks.
  • The nature of WSRP calls and how it all works on a very high level
  • The roadmap for OpenSocial and what we're planning to build on top of that for the next release (6.2)

This is another recording I did with some new recording gear, but, being new gear, I messed up the levels so I had to denoise it a bit, unfortunately a bit of noise still remains. I'm doing my best to get rid of that in future recordings.

And please remember to rate this podcast in your podcast directory of choice and provide feedback here on the episodes as well. Thank you.

Some listeners asked for an overview over the training courses that Liferay offers. Well - as I love feedback and try to do everything that gets suggested, I wanted to follow up on this suggestion. (This is a hint for all listeners: If there's something you're particularly interested in: There are good chances that I'm following up on that)

So I sat together with Jeffrey Handa, Senior Training Consultant and Project Manager at Liferay and we spoke about Liferay's training offers, the existing courses, the new offerings, what changes are planned for the next time etc..

We talked about

  • Jeff just had his 3rd birthray when we spoke, so he's in his fourth year now (I stole the term "birthray" from someone in the spanish office - can't remember who it was though, help me to get credit)
  • Jeff is one of the people with the "classic" way of joining Liferay - sorry, there's no interesting story here.
  • Jeff is involved in training: Preparing the material and actually teaching in trainings.
  • We're speaking about the training courses Liferay offers and Jeff gives some description of what the courses are about, also on the cooperation with liferay's knowledge management team. This includes the classic courses (PortalAdmin, PortalDeveloper, SystemAdmin) as well as the new courses (ThemeDevelopment and AdvancedPortalDeveloper)
  • some impressions of my (Olaf's) experience teaching portal admin training to customers that were using Liferay for some years already: They still got very good value out of it
  • What knowledge you should have before taking one of the new courses: "building a theme" and "advanced portal development"
  • Part of AdvancedPortalDevelopment is Writing Applications in webcontent. I have talked to Ray about this - he also has blogged about it.
  • Jeff is mentioning the ContentAdministrator course and the vision for what PortalAdmin can be about. Now I wonder if we will rename it to PortalNinja sooner or later.
  • Plans for what trainings will evolve to
  • What PortalAdminExpress is, when it is applicable
  • Trainings are available in several local languages as well.
  • Plans for certification and exams
  • Training is available on all supported EE versions - and public trainings will typically be held on the latest available EE version (but typically be released a bit after the EE release - if you expect the training to be on a specific version it pays to ask upfront. But we also speak about differences between the different versions, so that training is relevant for users of all versions of Liferay.

Having been raised the way (and time) I have been, I was particularly interested in one project that Liferay is involved in. So I took the opportunity and spoke with Nathan Shaw, Principal Consultant at Liferay, about one of Liferay's (literally) most colorful clients, who luckily has has agreed to be a topic in this podcast. With this, you get an impression of how a highly visible and intense project is structured and what's happening behind the scene. And you'll see a site that doesn't really look like your classic portal. Who am I talking about? Sesame Workshop.

We talked about

  • what your kids think of your work when you're always looking at the Sesame Street while pretending to work.
  • how Sesame frequently releases new content to the site - having fresh content and topics every so often is quite a task for the editorial team.
  • Big parts of what have been custom for Sesame geting into the product now (in 6.1), namely staging, versioning and branching (improved from the version 6.0 implementation).
  • Sesame being in the process of upgrading a high-traffic, high profile site from 5.1 to 6.1
  • the server infrastructure as well as some of the software background (e.g. Alfresco, GSA)
  • how is the site built - e.g. how much is stock, how much is custom? How is it all built?
  • We close with a discussion about how people do find Liferay and learn about the product and the company.

Something else...

Radio Liferay now has its own landing page at www.liferay.com/radio. So if you want to recommend this podcast to somebody, this is where you should point them to.

Also, I'd like to get more of your feedback: Do you feel this is valuable? Whereever you get the podcast - if there's an opportunity to rate it please do so - e.g. itunes currently does not have enough votes to display an average . Also, please provide feedback to the episodes so that I can balance the next topics and adjust them a bit more to your interest. You can do that on my blog or on twitter.

I do have a long list of community contributors that I'll contact in the next weeks to prepare some more recordings and mix them with the Liferay Employees as this whole program is not purely about the company people. Feel free to suggest more interviewees and topics though.

Thank you!

For the annual Liferay Retreat, I was in L.A. again and took the opportunity to record several new episodes - this one as a nice fireside chat - the first one with a live audience, though they have not been interacting too much - just been in the same room :)

In this session I talked with Greg Amerson, the author of Liferay's development tooling.

This is one of the first recordings on new gear, unfortunately levelling was not ideal, so it had to significantly be amplified and denoised - bringing some drawbacks in audio quality, mainly noise despite the denoising, but you'll be able to stand it - promised. Also, I hoped to get this out before the holiday season, unfortunately this didn't work out that well for various reasons - Sorry for that, you'll get your late christmas wishes in this episode.

Among other topics we talked about:

  • Greg got his exposure to Eclipse Tooling from being one of the first people to work on the MyEclipse product
  • The distincion between Liferay IDE (for Liferay CE) and Liferay Developer Studio (for Liferay EE)
  • The impressive size of the team to have worked on Liferay Tooling until now and from now on.
  • Greg's current location: Working from the China Office and how he got from Texas to China and the future plans.
  • The story how Greg found Liferay (you have to hear this - you might even learn your first words in Mandarin)
  • The difference the IDE support made in Developer Training - and what ideas he and the team have in addition of the current features (please provide feedback on what you expect from developer tooling)
  • Some of the ideas: Maven, personal templates, Marketplace, remote deployment and debugging
  • A vision for the stability of Liferay's plugin environment

For the annual Liferay Retreat, I was in L.A. again and took the opportunity to record several new episodes - this one as the first OpenAir recording. This also marks the advent of my new recording gear - expected to raise audio quality quite a bit.

In this session I talked with Bradley Wood. Brad is Frontend developer - involved in all things theme, CSS, Velocity. And he's maintaining a nice tumblelog with all kinds of Frontend tipps & tricks for Liferay (which brought him on my radar for the podcast).

Among other topics we talked about:

  • Getting theme custom settings (e.g. color picker) through the API - now standardized and extended due to popular demand
  • How Sass add power to CSS with variables (integrated in Liferay 6.1)
  • Compass, a library of Sass functions with vendor specific CSS3
  • Brad's style for creating a new theme, starting from photoshop, through CSS and Velocity
  • Parts of adopting a Look&Feel might involve hooks to change the core Liferay JSPs
  • Using structures and templates to improve the experience updating the content.
  • The alternative to routine when it comes to editing velocity...
  • Brad's tumblelog of Liferay Tipps&Tricks
  • the marketplace themes for particular industries
  • Think outside the box: How a theme can help you create an online shop by integrating google checkout
  • Liferay Foundation and how Brad if involved with its projects (World Impact, which is where Brad's first experience with Liferay came from - here are the Camps and Schools sites)
  • Upgrading themes from 5.2 to 6.0: How to handle the core css differences and vm
  • Recommendation: Have a common way to comment and format your code
  • How to use categories to simulate runtime-configurable theme settings in version 5.2 and 6.0 (as they are now standard in 6.1)

Liferay for your ears - I had the opportunity to record a session with 3/4 of the founders, namely all the Brians (simplifying the "y" in Bryan to "i" for this pluralization): Brian Chan (Chief Software Architect), Brian Kim (Chief Operating Officer), Bryan Cheung (Chief Executive Officer).

Some of the topics we talked about:

  • How they met and started to work despite different music and food taste
  • How or if college grades (might) relate to real life
  • While they used to live on the same floor some time, now they are still on the same planet...
  • Crazy organic growth and the hardest year, Rooming arrangements and sacrifices during the startup phase
  • The honorary Brian (the fourth founder, who could not join the recording), Mike Young, and why he should use EJBs for his marriage, what risk he took
  • How Caris put up with Brian's activity after 10pm and got Liferay's invoices off of notepad
  • The long term plans, "no exit" strategy and how a business can help to do good
  • And at the end the microphone unexpectedly turned around, and I give away pieces of my history with Liferay

Liferay for your ears - This time I sat together with Alexander Chow and Sergio González. Both are Liferay Core Engineers. Alex is "Employee number 8, UK employee number 1 (which gives away his location) and Liferay-Mac-User number 1. Sergio is Spain's employee number 6. Both have extensively cooperated in the new Document Library for Liferay 6.1 - now called Media Library - and this provides the main topic for us to talk about:

My shownotes:

  • Their background and what they worked on in Liferay
  • How to pronounce names
  • Naturally: The work both did on Document/Media Library and related portlets through the last year: The document library got a good rewrite, Ajax-based UI and a new backend to use Liferay as entry-point into other external repository systems.
  • CMIS (short for Content Management Interoperability Something - see link)
  • A lot of the document library backend war developed with JUnit and worked within a few days of work with the independently created UI when they were first brought together.
  • Different Document types are now first class citizens, so that you have certain metadata as well as separate workflows for different types of content.
  • Document Library and Image Gallery changed to Document and Media Library (for storage) and Media Gallery Display (for presentation) - the data and permissions will be automatically migrated
  • Previews for many document types will be automatically generated.
  • Listing alternative interfaces to the backend: Browser, WebDAV, Sharepoint protocol, Liferay Sync
  • Sync will work offline and synchronize any change (bidirectionally) with Document & Media Library when it's online, available for Windows, Mac, Android, iOS. Sadly there's one OS missing...
  • Iliyan is now europe's resident AlloyUI/JS expert
  • Download Beta 4 (or whatever is current when you read/listen to this) and give feedback, report bugs before Alex 2.0 is released.

Liferay for your ears - Meeting Michael Han, Liferay's Vice President of Operations, at the european symposium, I used the opportunity to record an episode on some of his working areas, namely security and performance. He gives some good background on these issues.

Among other topics, we spoke about:

  • His background, how he came to Liferay and what he's mainly working on
  • Mike is with Liferay since 4 years - helped setting up the international offices and business.
  • "Follow the sun" support: International offices required for support around the clock
  • Performance gains from version to version, sampling with logging in.
  • Mike's involvement in performance tuning, how the performance whitepaper is built and what you need to understand about your system in order to expect the correct results based on the performance whitepaper's numbers.
  • The different ways that the "number of users" can be interpreted and how to find out the required number of servers.
  • 3-4 man-years of effort go into performance-tuning enterprise edition
  • How to read security reports: Why 50 deep-red issues might show up to not be as bad as they look initially
  • Black-box and White-box testing for security issues
  • Circumstances under which a possible SQL-injection is not a problem
  • Security of Open Source software - with an example
  • How to report security issues: File an issue in Jira, set the component to "security" and the visibility to "private", so that only you and Liferay staff can see this issue. Enterprise customers just file an issue in their account and flag it as security issue.
  • How to set up a performing system, what parameters should you care for - along with some numbers we see on garbage collections etc. and why you can have too much memory.
  • There used to be a Sun/Oracle blog about every single JVM option since version 1.3, as we found out preparing these notes, this is no longer available. But there are alternative links
  • Other documentation for other vendor's JVMs
  • How we determine which server architecture to build the performance testing environment on.

Liferay for your ears: Episode 9 of Radio Liferay is another premier: This marks the first recording with more than one interviewee, as well as the first non-Liferay Employees. I used the opportunity during the european symposium to get together with Corné Aussems, Maarten van Heiningen, Milen Dyankov and Tomáš Polešovský, four Community Contributors.

podcast-logo Part of my original intent was to speak about their contributions and learn what Liferay can do better with regards to accepting contributions. Turns out that this was a handpicked crowd of notorious contributors that praised more than they criticized - well, so be it, it's good to hear this.

Among other topics, we spoke about

  • Naturally: The Symposium and what it's all about: Meeting people, the energy. All four of them work with/for Liferay Partner Companies. Stating also my personal recommendation: If you have any chance to make it to one of Liferay's symposium, make sure to go.
  • Tomáš best known contribution is the initial Extlet (now ext-plugin). This made it possible to move from the initial monolithic and huge ext-environment (singular) to very lightweight plugins (plural) in 6.0
  • Corné started with Liferay 3.x, is the Dutch translation leader.
  • Milen contributed the mobile device detection using WURFL, which he also demoed during the symposium.
  • Maarten is involved with themes, usability and accessibility. Also, he pushed "commenting as a guest", a new feature in 6.1
  • All of them contribute to many of the active community programs, Bugsquad, 100 paper cuts, etc. that James introduced.
  • Getting responses from core Liferay developers and personnell during the symposium and in the community.
  • Get knowledgable by learning from helping others:
  • Milen's and Tomasz's work on the Maven SDK

I hope that a lot of the enthusiasm that I've seen in this round as well as in any symposium I've been to can be transferred through the recording.

It was a great opportunity to get together with these guys, but sadly the episode is shorter than it could have been - we recorded this towards the end of the symposium, just before the community excellence awards were handed out - and as some of the participators were receiving them, I couldn't keep them busy for longer.

No children were harmed during the recording of this podcast - at least not by us: There were a few playing outside, running around and screaming - and the hotel room was not too soundproof, so this got onto the recording.

Liferay for your ears: Episode 8 is a premiere in this program: Brian Chan, Liferay's founder and Chief Software Architect, is the first that I didn't record in a conversation: Instead this is a recording from Brian's closing keynote at the European Symposium. I had originally planned to record an episode with Brian, but during this keynote he already answered 80% of what I had on my list - and added another 80% that I did not have on my list. So for now I settled with the keynote, well worth listening to

The introduction is done by Bryan Cheung, another member of Liferay's founding team and the Chief Executive Officer. As this is the full keynote, I really recommend to listen to it in full, and for that reason don't provide a bullet point list of the topics here. Just this: You'll learn a lot about the setup of the company, the vision, the reason why you want to work with Liferay - the product as well as the company. And why the company will stay with this vision for the foreseeable future. And where the name "Liferay" comes from. And so many more things - Brian is a fast speaker.

One of the next episodes will be a follow-up to this episode, as I used the opportunity to sit down with 3/4 of the founder's team, namely all the Brians (This poses a spelling problem: What's the plural of "Brian, Brian and Bryan"? I'll make it "The Brians")

  • Photoshop, Gimp, InDesign and other graphical editing tools
  • Aaron's hiring procedures

Let me introduce myself as the one who wants to be the resident german accent in your ears.

After a long time of "just intending" I finally went ahead and started recording a podcast about Liferay - the project, the product, the people and the company. Episode 0, a brief introduction with the intent and some generic information is available for manual download. It's only 4:12.

Episode 1 will be out within a day - I sat together with James Falkner, Liferay's community manager, who luckily agreed to be my guinea pig. Episode 2 is - contrary to what I say in episode 0 - already recorded and will need a bit of post-production. Stay tuned for this - I'm speaking with the Alter Ego of "Rich Editor".

You might have noticed that I said "manual download" - there's no feed yet. But as I had the content, and it's kind of timely because we talk about the symposiums, I wanted it out in public as soon as possible. So please bear with me while I create a feed that somehow contains what the typical feedreader - especially itunes - does expect. The whole setup, hosting etc. is temporary and will change soon.

So use this to practice manual download and listening to yours truly. Episode 1 will probably also predate the feed, but it should not be by far.
