2009 - A Year in Review

I wrote my first "year in review" post in 2005 and continued the tradition in 2006 and 2008. This year, my December was filled with unplanned circumstances, a new job and a houseful of family for the holidays, so I never had time to sit down and write this post. As things are returning to normal, I figured it's about time I kicked off 2010 with one of my favorite writing reflections.

2009 started off with a bang: I wrote about my Mom nailing a bear's nuts to a tree after she killed it. My new gig (at Evite) started out fun with choosing an Ajax framework and a Tech Meetup in LA. My bike got stolen, I started running to work and traveled to Tahoe without an ID.

February started off with an epic weekend at Silverton. I went to Web Directions North and attended many good talks:

• Changes in the Languages of The Web
• The State of the Web 2009
• Ajax: The State of the Art

I wrote my first GWT-related entry and a few posts related to independent consulting.

• How To Setup Your Own Software Development Company
• Writing Off Home Office Space
• What's the Best Retirement Plan for Independent Consultants?

I ended February with a couple more GWT-related entries.

In March, I bought a new 15" MacBook Pro and shipped it back shortly after to get a 256 GB SSD. I still have nothing but good things to say about the machine. I discovered Nexus is awesome and the kids and I went on our first hike of the year.

My GWT Journey continued with GXT MVC, modularization and optimization. I got a new office and new bike and proudly witnessed my Dad's Retirement.

April came and I got Drunk on Software, had a blast at Holly and Jason's Wedding and published our Ajax Framework Analysis Results.

At the end of April, I started building the kids a treehouse and inspired smiles with two new kittens. On May 7th, I had PRK eye surgery and wrote about my experience in early June. I continue to be extremely happy with the results.

May ended with Ryan and Breanne's Wedding in Playa Del Carmen. Having so many great friends around and the Nuggets vs. Lakers playoffs the same week made this one of the best vacations of my life.

June brought the news that the Colorado Software Summit was over. There's been several times in the past few months that I've missed the annual experience. Can someone please start a conference at a Colorado mountain resort in the near future? Pretty please! I've always experienced this conference with Bruce and we continued another tradition (riding to Red Rocks) with 2nd Row seats at Big Head Todd.

My GWT posts continued with a Facebook-style Autocomplete, Implementing OAuth, JSON Parsing with JavaScript Overlays and a preview of GWT 2.0. I wrote about implementing SOFEA with GWT and Grails at Evite.com and had a blast at the Great Sand Dunes on Father's Day.

My job hunt began and I started a month-long vacation in Montana with Raible Road Trip #13. Vacationing for a summer month in Montana has been one of my goals for several years. Accomplishing it this year made me extremely happy and I hope to make it a summer tradition.

July was an awesome month in 2009. Granted, April and May were special with tropical weddings, but Montana in July is a particularly tasty treat. My Summer Vacation in Montana attempts to capture how much fun we had. It was particularly enjoyable because my parents, children and many life-long friends were involved.

As summer began to set, I decided to get back into speaking at conferences, starting with the Rich Web Experience. I wrote about initial GWT work at my new client, which included an interesting experience with Java REST Frameworks. The month ended with one of my favorite holidays: Jack's Birthday.

September was nice and uneventful. I learned about Concurrency on the JVM Using Scala, started using MVP with GWT and learned how to do more with less. I also ran in a 10K.

October started out with a family trip to Washington for my sister's fabulous wedding. People flew in from all over the US and we had a sweet condo on Lake Chelan for the week. Playing golf, wine tasting and celebrating with good people made for a great start to the fall season.

In November, I started writing more, mostly because I was gearing up for upcoming talks and thinking about / working on AppFuse. I celebrated Abbie's Birthday, did some website optimization and chuckled at the comments about my hunting season adventure.

Right before Thanksgiving, I got a call from my client letting me know that their budget had run out my contract would end soon. Luckily, I had an interview setup the next day and had great success in finding a new gig.

I ended November with a trip to Oregon for Thanksgiving and ran in the Oregon Mid-Valley Road Race. The followed week, I flew with my kids and parents to The Rich Web Experience and learned about Objective-J and Cappuccino. I had a near-perfect (high 70s, no lines) Disney World experience with my family, watched the Ducks with the Civil War and compared kick-ass web frameworks.

In December, I didn't do much blogging - mostly because I arrived home from Florida to discover a waterfall in my guest room. The water pipes were routed through the ceiling, had busted from the cold, and water was pouring everywhere. Dealing with that and starting a new job occupied most of my time and I never got a chance to write much down. I ran in the Jingle Bell 5K and watched the Broncos lose a lot. Shortly after, my family came for Christmas and a good time was had by all.

As I reflect back on last year, my biggest surprise is that I got into running. I ended up running in 5 races last year and even enjoyed doing it a few times. It's still not my favorite activity (skiing and mountain biking win that title), but I enjoy it enough to do it a couple times each week. The goals I wrote down for last year were: visit 3 foreign countries, take 3 months of vacation and spend 1 month in Montana. I only made it to 1 foreign country (Mexico), but I did take 2 months of vacation and got my month in Montana. I'll take that.

In 2010, I hope to speak at (or attend) 3 conferences, finish up The Bus and do a whole bunch of skiing and mountain biking. More than anything, I plan to continue having a lot of fun with my family and implementing a lot of cool technologies along the way.

It's gonna be a great year.

Adding Expires Headers with OSCache's CacheFilter

A couple of weeks ago, I wrote about how I improved this site's YSlow grade by concatenating JavaScript and CSS with wro4j. Even though I loved the improvements, there was still work to do:

I'm now sitting at a YSlow (V2) score of 75; 90 if I use the "Small Site or Blog" ruleset. I believe I can improve this by adding expires headers to my images, js and css.

Last Monday, wro4j 1.1.0 was released and I thought it would solve my last remaining issue. Unfortunately, it only adds expires headers (and ETags) to images referenced in included CSS. Of course, this makes sense, but I thought they'd add a filter to explicitly add expires headers.

Since I still wanted this feature, I did some searching around and found what I was looking for: OSCache's CacheFilter. It was surprisingly easy to setup, I downloaded OSCache 2.4.1, added it to my WEB-INF/lib directory, and added the following to my web.xml.

<filter>
    <filter-name>CacheFilter</filter-name>
    <filter-class>com.opensymphony.oscache.web.filter.CacheFilter</filter-class>
    <init-param>
        <param-name>expires</param-name>
        <param-value>time</param-value>
    </init-param>
    <init-param>
        <param-name>time</param-name>
        <param-value>2592000</param-value> <!-- one month -->
    </init-param>
    <init-param>
        <param-name>scope</param-name>
        <param-value>session</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>CacheFilter</filter-name>
    <url-pattern>*.gif</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>CacheFilter</filter-name>
    <url-pattern>*.jpg</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>CacheFilter</filter-name>
    <url-pattern>*.png</url-pattern>
</filter-mapping>

After restarting Tomcat and clearing out my Firefox cache, I was in business.

I did experience one issue along the way when I tried to remove the oscache.jar from my WEB-INF/lib directory. I'm using the JSPWiki Plugin and it seems to rely on a class in oscache.jar. I'm not sure which version oscache.jar is, but the packages got moved around somewhere along the way. The good news is it seems OK to have both oscache.jar and oscache-2.4.1.jar in Roller's classpath.

After discovering the duplicate JARs issue, I got to thinkin' that EhCache would probably have a solution. Sure enough, it has a SimpleCachingHeadersPageCachingFilter. Since I already had a working solution, I didn't bother trying EhCache (especially since my Roller install uses EhCache 1.1 and the filter is only available in a later version). However, when I implement expires headers in AppFuse, I'll definitely try EhCache's solution.

As for my YSlow score, it didn't improve as much as I'd hoped (low 80s instead of mid 80s). Some of this is due to my embedded presentation from Slideshare. There's also some external images I'm using in my Lightbox JS implementation. So if I can find a better Lightbox implementation (supports rel="lightbox" syntax), there's a good chance I'll switch. In the meantime, I'm lovin' how much faster this site loads.

In case you're wondering, I do plan on adding css/js concatenation and expires headers to both AppFuse 2.1 and Roller 5.

Update: FWIW, I did try to configure expires headers in Apache, but the AJP 1.3 Connector doesn't seem to allow this to work. To quote Keith from KGB Internet:

I added an expires directive and it didn't touch the header for anything served from Tomcat, but does for content served directly by Apache. This might have to be set up in Tomcat.

JavaScript and CSS Concatenation with wro4j

This past weekend, I decided it was about time to fix my YSlow score on this site. I did the easiest thing first by moving all my JavaScript files to the bottom of each page. Then I turned on GZip compression using Roller's built-in CompressionFilter. These changes helped, but the most glaring problem continued to be too many requests. To solve this, I turned to wro4j (as recommended on Twitter) to concatenate my JS and CSS files into one.

I have to say, I'm very happy with the results. I'm now sitting at a YSlow (V2) score of 75; 90 if I use the "Small Site or Blog" ruleset. I believe I can improve this by adding expires headers to my images, js and css. More than anything, I'm impressed with wro4j, its great support and easy setup. I was looking for a runtime solution (b/c I didn't want to have to rebuild Roller) and it seems to be perfect for the job. Furthermore, wro4j minifies everything on the fly and they'll have an expires header filter in the next release.

JAWR and the YUI Compressor are other alternatives to this filter, but I'm currently sold on wro4j. First of all, it passed the 10-minute test. Secondly, it didn't require me to modify Roller's build system.

At this point, if I'm going to implement JS/CSS concatenation and minification in AppFuse and Roller, wro4j seems like the best option. If you disagree, I'd love to hear your reasoning.

TIP: See Javascript Compression in Nexus for information on using YUI Compressor with Maven.

2008 - A Year in Review

In 2005 and 2006, I did "A Year in Review" entries. 2007 was the year I got divorced, which probably motivated me to write a bit less. This year I'm back and ready to spend the next few hours writing, copying/pasting and linking like a madman. Hope you enjoy!

2008 was the year I traveled the world and developed a true passion for skiing. In January, my good friend Jason Miller moved back to Denver after quitting his job at Bear Stearns in NYC. We spent the first weekend in Nebraska working on Cletus's feedlot. The next week, my car stereo got stolen and I wondered if my bad knee would make it through the ski season (the good news is not only did I ski the rest of the season, but my knee healed itself over the summer).

At the end of January, the kids and I hiked to the top of Green Mountain and Don Brown made Maven not suck. Then I wondered if there was room for both Rails and Grails at a company and quickly learned both.

February started fantastically with a 14" Powder Day at Steamboat. I wondered if there is no "best" web framework and reviewed Grails and Rails books. After spending an awesome weekend in Tahoe, I took the kids on The Ski Train and learned more about Selenium at Google.

This brings us to one of my favorite posts of all time. On February 28th, Jack got a bead stuck in his nose. After taking him to the ER and paying $800, we found out magic recipe for bead removal is to "hold one nostril and give him a CPR-type breath/blow into his mouth". The reason I love the post so much is it's solved the problem for other frantic parents when they Google for "bead stuck in nose". Whenever I get a new comment, it always makes me smile.

March started out with a Powder Day at Whistler. I thoroughly enjoyed the rest of the weekend with good friends Jarvis and Korn Dog. After returning to Denver, I was allowed to blog about building a UI Frameworks Team at LinkedIn and posted my thoughts on Grails vs. Rails.

In mid-March, I achieved an all-Mac family and traveled to Lake Chelan for my sister's birthday. Shortly after, The AppFuse Primer was released. At the end of the month, I attended TSSJS in Vegas and moderated a Web Framework Smackdown.

In April, the LinkedIn Denver office opened and we all celebrated by attending the Rockie's Home Opener. The ski season came to an end and I wrote a howto for configuring Apache with mod_proxy and SSL on OS X. Then I discovered the JavaOne parties and wrote about running Spring MVC Web Applications in OSGi.

April ended with 82°F and May started with snow. I attended JavaOne (or at least the parties), released AppFuse 2.0.2 and figured out how to do extensionless URLs with the UrlRewriteFilter. The kids and I spent an afternoon in Rocky Mountain National Park and I did some coding in my backyard.

On Memorial Day, I enjoyed a liver-wrenching, Rockies-filled weekend with my sister her girlfriend Mya and Mr. Miller. I also contemplated making AppFuse Struts 2-specific.

June started with some mountain bike riding, planning some excellent vacations and getting a dream machine. I rode the annual trip to Big Head Todd at Red Rocks with Matt and Bruce. I took the kids on their first camping trip for Father's Day and had a blast. It took us several hours to find the campsite and my car kept starting all night long. It's sure to be a family tradition from now on.

The next weekend, I attended the American Craft Beer Fest in Boston. To end the month, I embarked upon Raible Road Trip #12 with Abbie, Jack and my Dad.

In July, the bus project began and I posted pictures of the trip to Montana. This year, I hope to spend the whole month of July at the cabin. I bought an iPhone (one of my best technology-related purchases to date). OSCON was fun but the week after wasn't.

August revealed my favorite birthday present. I didn't blog much the rest of the month, revealing why later.

Jack's Birthday Weekend was an outstandingly fun mixture of old friends and good Colorado beer. In September, I went to see the bus at MotorWorks, Abbie lost her first tooth and co-workers and I performance tested Memcached.

What followed was wonderful. Miller and I headed to Oktoberfest for the Best. Vacation. Ever. We still talk about how much fun we had on that vacation. October finished with the Colorado Software Summit and a hunting trip to the cabin.

November was a crazy month. I got laid off and celebrated Abbie's birthday on the same day. Jack got a mohawk and I traveled coast-to-coast in the same week. To close the month, I announced what's next and headed to Costa Rica.

I had a fantastic time in Costa Rica and was impressed to see Abbie is a blue skier shortly after. I did a Dojo/Comet Research Project for a week and enjoyed the location of my newest client last week. A small adventure turned into a scary adventure and I enjoyed telling my stories to fellow Java Enthusiasts in Portland.

Phew! It's been quite a year. For 2009, I'm still hoping for what I tweeted shortly after Costa Rica. I'd like to visit 3 foreign countries, take 3 months of vacation and spend 1 month in Montana. I have technology goals too, but those aren't nearly as much fun to dream about.

Happy New Year!

All my favorite Feed Readers are now free!

I've been using NetNewsWire ever since I started subscribing to feeds back in October 2003. A year or two later, I bought FeedDemon for my Windows box and synced them up using their online sync feature. When I got a BlackBerry Pearl almost a year ago, I bought NewsGator Go!. While the online sync hasn't worked very well between all these applications, I've generally been very happy with them and haven't been inclined to switch.

Now there's no good reason to ever switch:

NetNewsWire 3.1 is free!

By free I mean both that we've released it from its cage and that it costs no money. Zero dollars.

Upgrades are free. It's free for new users. It's freeware.

You can download it right away. Here are the change notes.

NetNewsWire is not alone -- we've also made FeedDemon, NewsGator Inbox, and NewsGator Go! free.

Thanks NewsGator!

Tech Meetup in Silicon Valley next week?

Dave's going to be in California next week:

I'm going to be traveling to California next week (Jan 13-18) to sync up with my co-workers at Sun HQ in Santa Clara. I'll be in town Sunday through Friday and though my days will be pretty busy, I'll probably have some free time in the evenings for a meet-up or two.

Coincidentally, I'll be out there as well (Tuesday - Friday @ LinkedIn). Sounds like an excellent excuse to meetup and have some beers. Wanna join us?

Upgraded to Roller 4.0

This site is now running Apache Roller 4.0. If you see anything funky, please let me know. As part of the upgrade, I did a bunch of spring cleaning, so it's possible I deleted some files I shouldn't have. As far as upgrading, the only issue I know of is this one where my categories are no longer in the same order. Since it didn't seem possible to fix easily, I decided to not worry about it and go ahead with the upgrade.

If you'd like to take Roller 4.0 for a test drive, you can use the Test Blog on this server. Username is test, password is roller.

I dig the new entries and comments counter:

This is the Hottest Blog on Programming

I received an e-mail this morning that said the following:

Congrats! Your blog has made it into the TOP 50 of The All Night Coder blog community, powered by SocialRank!!!

Then I clicked on the link they supplied and discovered I'm #1! Since I know it won't last, I figured I'd better take a screenshot.

Apache Roller, Acegi Security, LDAP and JA-SIG CAS

Earlier today, I delivered my talk on Apache Roller, Acegi Security and Single Sign-on. As part of this talk, I put together a couple of tutorials you might find useful:

• Roller 4.0 with LDAP and CAS
• Roller 4.0 on Geronimo

NOTE: These tutorials are using Roller's trunk as we found some things to simplify LDAP integration tonight.

You can download a PDF version of my presentation from my publications page.

During the presentation I did a number of demos:

• Installing Roller on Tomcat
• Integrating Roller with Apache Directory Server
• Integration Roller with CAS
• Integrating CAS with LDAP

Rather than saving the demo for the end, I did it as the first part of my presentation. This worked extremely well - especially since I didn't have to worry about running out of time.

If you're using Roller, have you integrated it with LDAP or another SSO solution? If so, is it working well for you?
