Firefox and the lack of a developer community

Joe points to some interesting news about Firefox. The part that struck a cord with me is Mike Griffin's post about free products and burn-out.

As a co-author of a free product myself I know the kind of burn-out issues these folks are going through. Most folks working on free products need real jobs to pay the bills. This means they work on these free products late into the evenings and on weekends if it's a product of any real worth.

At first the thrill of a new project and the recognition that goes with it carries you through those tiresome evenings. You are creating something new and there are no bean-counters around to mess everything up. However, as time goes on, as with most things, the thrill begins to wax and wane, and after months of getting no more than 4 hours of sleep per night it begins to affect your health. You get sick more often than you used to, and you're main goal quickly becomes to merely get through each day. And then there's the guilt of spending too much time on it, when the basement needs painting, things need fixed around the house, and you're not spending enough quality time with your kids (and when you do you're the walking dead so it doesn't count). Finally, and much to your surprise, the project doesn't really turn out to be the big career booster you thought it was going to be. In fact, perspective employers are hesitant to hire you when they find out you have a mistress on the side pulling at your time and resources.

In the end, it's a matter of commitment. You've created something folks have come to rely on and they need you, you cannot walk away from it. You realize how foolish you were thinking that it was all going to be good times and not tough times (like at work) and then you hunker down for the long haul. There are ups and there are downs, in the end you a providing a free product and you have to pace yourself. There isn't a day that goes by that I didn't wish my free product was my real and only job, but it isn't, and I knew that when we started it.

I couldn't have said it better myself. I've definitely experienced the "affects your health" part, but I can't agree with the career booster part. Maybe I've just been lucky, but I believe my extra-curriculars continue to help my career.

That being said, I'm burned out on both AppFuse and Spring Live at the moment. Luckily, I'm committed and will be able to find motivation for both of these projects in the near future. There are sooo many nights when I work on these projects and I'd much rather just go to bed or weekends when I wish I could goof off and play with the kids. The nice thing is that I can choose to do this stuff. Users may scream and readers may complain, but sanity and family must have a higher priority.

I've only stayed up late once in the last two weeks and I didn't touch the computer for more than 5 minutes this last weekend. With this week being a 1-day work-week (the rest being spent at Microsoft and on vacation), I should be rejuvenated and enthusiastic about working for free again soon.

Brian McCallister hits the nail on the head with his comment. For an open-source project to remain successful long-term, it needs a strong developer community. "A project with a truck number of two is in deep trouble." Seems like recruiting new developers might be more important than new releases. Something to think about...

Sun, Hockey, Snow and Skiing

This weekend was another great example of why it rocks to live in Denver. On Saturday, Holly (Julie's sister) hosted a house-warming/birthday party and we enjoyed a few Coors Lights in the 70 degree weather. Saturday night, I took Abbie and a couple of friends to the DU Hockey game, and when we left it was snowing. Sidenote: Abbie has switched from calling it "Hockey" to "DU Hockey" and she's becoming very well versed in "Go DU!".

I woke up early yesterday morning, picked up a friend and after 2 hours of nasty roads and traffic, we were skiing Keystone at 10. There was 5 inches of fresh powder and the sun was out - meaning it was a beautiful day to be on the slopes. This morning it's still snowing and expected to continue for a few more days. I'm sure we'll get spring weather again soon, but not soon enough for Julie.

Discrimination by Light Rail

After a late night wrestling with AppFuse and Acegi Security, I decided to take it easy this morning and ride my bike to the Light Rail, then ride it downtown. I figured it might be a bit faster, and it'd also be nice to relax a bit more on the "commute". I arrived at the station as my train was leaving, so I quickly realized that it was probably not going to be faster, but it would probably take the same amount of time. I was still determined to be a sissy and not ride my bike to work. When the next train pulled up, the conductor got on the loud speaker and said "30th and Downing Station, No Bikes Sir." WTF?! I gave the guy a boboli¹ and grumbled to myself.

So I ended up riding to work today anyway. I took the Platte River Trail², which was a nice change of pace, but it was also closed in one spot, so I had to take a detour. Long story short: every time I try to cheat the ride to work by driving, taking the bus or light rail, it always backfires. Riding to work using the Wash Park/Cherry Creek Trail route is simply the fastest way to get here, bar none. Took me an hour to get here via Platte River. Oh well, at least it's a nice trail.

Spring MVC vs. WebWork Smackdown at OSCON

Matthew Porter and I are going to try something a bit different at this year's OSCON. Rather than just getting up in front of the crowd and spewing our technical know-how, we're actually going to make a go at providing some entertainment. I've been to a lot of conferences and I'm tired of just watching someone talk - I'd rather see a good presenter over a knowledgeable presenter. This has inspired our OSCON 2005 talk:

This presentation has a unique delivery style. Rather than one person doing a comparison, there are two presenters - each which is an expert in the framework they're defending. The presentation is delivered as a friendly comparison/debate, which hopes to add some humor in to make it fun for the audience.

Java web developers often have a difficult choice when choosing a web framework these days. There are currently more than 35 open-source Java web frameworks available. How do you which one to use for your project? This presentation picks two of the most popular frameworks, Spring MVC and WebWork and compares and contrasts their features. Topics will include:

1. View options - i.e. Velocity, JSP, HTML Templates (ala XMLC), etc.
2. Testability - How easy is it to unit test with JUnit, with examples
3. Type conversion - i.e. Date, Integer, etc.
4. Validation - How do do it, stengths and weaknesses
5. Tools Support
6. Strengths and Weaknesses

Now the pressure's on - we have to both teach and entertain the audience. Please feel free to post your experiences with Spring or WebWork and why you think one is better than the other.

Display Tag being ported to Ruby/Rails

Found via Brian McCallister - a codefest grant has been awarded to Dave Tiu to reproduce the Display Tag in Ruby/Rails.

Codefest Grant recipients:

1. Ruby Displaytag (Dave Tiu)

A port to Ruby/Rails of a popular Java/Struts library for displaying
and interacting with HTML table presentations.

Maybe if I wait a little longer to write my first Rails app - they'll add client-side validation too.

Is Laszlo a waste of time?

According to Rife founder Geert Bevin, Laszlo ain't all it's cracked up to be:

It's a shame, I really had huge expectations about Laszlo and even tried to sell it to a customer. I'm glad that project was cancelled or I would be in deep trouble.

Under normal circumstances, I'd dismiss this as FUD, but Geert sounds like he did his homework on this one.

Simple Web Framework

You gotta admit, the Simple Web Framework does look interesting with all of the recent Ajax talk:

The Simple Web Framework (SWF) is an event based framework targeting Struts developers who want to build rich Web applications but do not want to migrate to JSF. The SWF is built upon the same Jakarta commons basis as Struts, but uses a different request processor (front controller.) The SWF event model supports form/submit style event posting, similar to VB.NET or JSF, as well as XmlHttpRequest based event posting with In place Page Updating (IPU) rather than page reloading, similar to the techniques underlying gMail. Read the SWF Overview for additional information.

My hope is that all web frameworks have some support for IPU by the end of the year. Then I won't have to build it into AppFuse.

Ajax webapps are cool, but non-javascript versions still needed

I think we can all probably learn a lesson from Google. I've heard that GMail is the "gold standard" for Ajax applications. If that's the case, then you should note that they've recently added a "basic HTML" link to the bottom of their pages. With this link, you can view your e-mail using the old way: Yahoo-style, no-JavaScript-needed. My guess is they added it because of demand, or simply to compete with other providers who have this feature. I think it's a good lesson though: use Ajax features in webapps where appropriate, but don't make JavaScript necessary to use your app.

A couple of Ajax features I've been thinking of developing:

• Saving forms with XMLHttpRequest: just display a success message at the top, and switch the "Cancel" button to "Done". Since the form's content doesn't change, this seems like a reasonable use of the technology.
• Switching out entire "content" <div> elements. Most of my apps have a <div id="content">, so it'd probably pretty easy to just replace that in response to button and link clicks. Of course, the hard part is having the requested server-side object load the view template, process it, and send back the content. This is probably more trouble than it's worth.

[TSSS] BOFs, Booze and Benitar

On Friday night, I attended all three of the 7:30 Birds of a Feather sessions. The first one I went to was Spring, where Rod talked about what's coming in Spring 1.3. Rod did a 25 minute presentation on the new stuff and then opened the floor up to Q and A. The session was well attended and I skipped over to the Tapestry/Trails BOF when the Q and A started.

I was surprised to find that very few folks where at the other BOFs. While the Spring BOF had 50+ attendees, the Tapestry one only had around 15-20 and JSF had around 8. I quickly left the Tapestry/Trails BOF when Chris started walking through his Trails Video. He was doing a live version of it, and since I'd already seen it, I figured I wasn't going to learn anything new. I've also been following Trails since it first started, and was more interested in talking about Tapestry.

I walked into the JSF BOF as Ed was talking about JSF 1.2 and what's next for JSF 2.0. This was good timing as I had a few suggestions for 2.0: HTML Templates like Tapestry, bookmarkability (don't make everything a post) and thinking about tools like Tiles and SiteMesh. While neither tools is part of the spec, I think they should be remembered in case there's an opportunity to make integrating with them easier. Ed did mention that JSF 1.2 has pretty much solved the content-interweaving problem, so putting HTML in your JSF JSPs should be better supported.

The very interesting part of this BOF is that Ajax capabilities are very much on the radar for JSF 2.0. They plan on providing native XMLHttpRequest capabilities. My suggestion for this was to provide the setup and registration of requestable class methods as part of the framework, and leave writing the JavaScript to the developer. This was a good BOF and I'm pumped to see that JSF is embracing the next-gen way of developing webapps. Let's just hope JSF 2.0 is released this year and not 2 years from now.

After the BOFs, I joined Matt and Jim to wait for one of Matt's buddies (Scott) to come into town. After he arrived, we headed over to the OpenSymphony open bar at the Bellagio. There, I got to meet Patrick Lightbody and enjoyed several beers and good conversation with the likes of Seth Ladd, Thomas Risberg, Mike, Dion and Christian.

After the open bar closed, Jim, Matt, Scott and I headed just off the strip to the Gold Coast Casino. Matt and Scott wanted to find some poker (tables had a 2-hour wait on the strip) and Jim and I wanted cheap Blackjack. We were pleased to find $5 tables and stayed there for several hours. I don't know what time we headed back to our hotel, but I'm guessing 1 or 2. The rest of the night was pretty funny. Jim and I gambled until 7 in the morning at several blackjack tables. Our hotel had this "celebrity theme", so we had dealers like Pat Benitar and Stevie Wonder throughout the morning. Both of these dealers were great and I got "hooked up" on several occasions. There were at least 10 times where I asked for a card and they didn't give it to me (after which I won b/c they busted). We ended the night at 7:00-7:30 with 5 crisp $100 bills in my pocket. Total cost of the whole trip: $100. Not bad eh?

Getting home yesterday was quite an adventure. After going to bed at 7:30, I woke up by some miracle at 11:00. I don't know if I had a wake up call or what, but my buzz was still in full swing. I caught a cab and headed to the airport. I paid the cabbie with a $25 chip, which he didn't like, but after I told him to keep the change (it was a $6 cab ride) - he happily obliged. At the airport, I took a nap while waiting for my flight to board and almost missed it. They called my name over the intercom b/c I was the only passenger left to board. Luckily, I was awake and made the flight. Upon arriving in Denver, I walked to my car and promptly locked my keys in the trunk. The airport officials got them out for free and I made it home to a very happy family around 6:00 p.m. It's good to be home.

[TSSS] Days 1 and 2

I'm sitting in the EJB3 BOF right now. The room is packed, but it seems most folks are uninterested and the moderators are just talking amongst themselves. Seems like a good time to blog since this BOF doesn't interest me whatsoever. Yesterday, I arrived at 8:00, took a cab to the Imperial Palace (where we're staying) and then headed over to Caesar's for the conference. I registered, assured we could drink beer during the sessions, and attended the (rather dry) keynote. Hani has a good synopsis of this talk.

After the keynote, I went to Patrick and Jason's WebWork talk for about 10 minutes. I soon realized it was an intro to WebWork and left to try and learn something. I went to Craig McClanahan's talk on "The Development of Web Application APIs and Standards for Java." His talk was pretty good, and covered "de facto" versus "de jure" standards. De facto standards are ones that evolve from the community through widespread usage, whereas de jure standards are imposed on the community (like JSF). Again, Hani has the full scoop on this talk.

Next, I went to Dion and Ben's talk on Ajax applications. They talked about XHTML/CSS and how XMLHttpRequest makes rich client-side applications possible. I think the whole Ajax thing is pretty funny. It's something that's been available for several years and my guess is most folks just didn't know about it. I've been using XMLHttpRequest for a couple of years now, and it's interesting to see it become popular all of a sudden. It's quite nice actually. I've been writing HTML/JavaScript for over 10 years, so I find Ajax development pretty easy. I hope to add support for Ajax-type features in AppFuse before this summer.

I wonder when/if the community will realize the power XSL processing in the browser? Since we're all developing XHTML applications now, our pages are XML and we could easily start leveraging client-side XSLT to do some pretty cool stuff. With a client-side XSL sheet, you could do page decoration (like SiteMesh) just by adding one line to your pages. For example:

<?xml-stylesheet type="text/xsl" href="styles/global.xsl"?>

The only problem with client-side XSLT is your pages have to be well-formed XML or everything bombs. With HTML, if you screw something up, chances are the browser will still render it correctly.

After the Ajax review, I had lunch and headed down to the Casino for some beers and gambling. I came back in time for Rod's "Why J2EE Projects Fail." It was a good talk, but there wasn't any revolutionary or new information provided. After his talk, I was motivated to learn more about Web Services Security, but instead opted for beers with Crazy Bob, JIRA Mike and Neon Dion. A couple of beers turned into several, and I found myself having dinner with the SourceBeat guys (Bill, Matt and Jim) a couple hours later. Steak and Lobster was my plate of choice and it tasted quite good. The rest of the night was spent gambling, drinking and harassing Pai Gow Poker dealers. We had breakfast around 2 and made it to bed by 3. Total cost of the trip so far: $300.

I slept in until noon today, after which Jim and I headed back to the conference for some lunch and afternoon sessions. Lunch was good and followed by Oracle demoing JDeveloper and coding EJB3 and JSF with it. I've often wondered about the cost of Oracle's ADF JSF implementation and actually got an answer from one of the attendees. I think he was an Oracle employee but he basically said you have to buy at least 1 copy of JDeveloper ($999) and you get a runtime license for ADF Faces as part of that. That sucks because Oracle's implementation looks like one of the most full-featured ones available. Why should I have to buy a tool I'll never use just to use ADF Faces?

After lunch, we attended Rod's "Advanced Spring Framework" and Craig's "JSF: Dead on Arrival or Raging Success". Rod's Spring presentation covered some advanced Spring features: autowiring, inner-beans, lists, instantiation choices, factory beans and template bean definitions. The presentation was good, and I was pleasantly surprised to find I knew most of the things he covered. Colin spoke about using JDK 5 annotations for transaction demarcation and Keith talked about Spring Web Flow. The Spring Web Flow stuff looks cool, especially since the other framework developers are listening and liking what they see. Craig even mentioned that he'll probably ditch what he's put together in Shale and use Spring Web Flow instead.

Craig's talk about JSF was rather boring, but most of these sessions are (mainly because there isn't a whole lot of new information). Craig did manage to pimp Java Studio Creator a bit. I find JSC demos to be quite funny since it hides so much code with code-folding. In the demo, Craig showed us a 10-line Java class that made JSF (and JSC) look like good stuff. Jim and I noticed code-folding was turned on and the class was actually 120 lines long! This is more of a problem with JSC then JSF IMO. The one nice thing about this talk was learning that a JSF 2.0 BOF is tonight. The main goal of the BOF is to see what the community wants in 2.0. I hope to attend and express a desire for HTML templates like Tapestry has.

Tonight kinda sucks because all the good BOFs (Spring, Tapestry and JSF 2.0) are at the same time (7:30). I'm hoping to hop around between them and get some good networking in. After the BOFs, OpenSymphony is hosting an open bar - so that should be a good time. Hopefully we can scare up a few free carbombs.
