CFMX 7 Podcast Series: Clustering and Sourceless Deploy

Second in this series of podcasts is a reading of the Macromedia Devnet article on managing clusters by Geoffrey Greene and Erik Tierney.

Managing Clusters with Enterprise Manager and Packaging Applications in ColdFusion MX 7
Package and deploy EAR and WAR files, and manage instances and clusters with the Enterprise Manager.

To subscribe to the ColdFusion podcasts you can set your podcast-enabled blog aggregator such as iPodderor Feed Demon to the ColdFusion Podcast RSS 2.0 feed.>.

This sound quality of this podcast is an improvement over my first now that I'm using a professional microphone, although it was a challenge to complete the reading since I'm just recovering from a cold where I lost my voice last week. After having read Jake Ludington's article titled, Create Podcasts Using Your PC, I decided that the toy microphone that had sitting around wasn't going to cut it and I would need something better. I used his article on creating a podcasting kit as a guideline.

I purchased a microphone and a pre-amp at a Guitar Center in Natick for a much better price than anywhere online. I couldn't find a cheap mini compressor anywhere so I decided to opt out of that. The service at Guitar Center was great a gentleman named Alain explained everything I would need to know from how to use a pre-amp to which buttons to push and where to plug in the various wires.

Obsessed with Blogging?

At 10 pm, my wife walks into the living room and sees me on the couch with the widescreen laptop illuminating the walls.

She says with a sigh, "my husband ... the blogger".

I tried to explain the whole getting blogged by Dave Winer thing... she didn't get it.

Podcast Unto Others, As You Would Have Others Podcast Unto You

O'Reilly blogger Jake Ludington published the second article in a series about podcasting. I'm skimmed them so far and I'm about to give them a careful read since they appear to be clear and comprehensive. - A directory of cool stuff for the podcasting community

Blogging's Founding Father, Dave Winer, who first envisioned podcasting, has launched a new site tonight, Podcatch to act as a respository of knowledge for the podcasting community.

I commented on his initial post about my intentions to start podcasting Macromedia technical content, move on into interviews and such, and then reach out into creative podcasting when my experience matures.

Dave picked up on my comments and blogged it on Scripting News, where he relates to my experience as one of those moments where the lights suddenly go on.

Check out this one hour interview with Dave on IT Conversations. He discusses his first course in computing after following his father's advice, to starting his first business, running Userland Software, developing XML-RPC, SOAP, RSS, and podcasting. If you're not listening to IT Conversations regularly, you should be!

New ColdFusion MX 7 Podcast Series

Today I'd like to launch a new ColdFusion podcast series where I'll be reading articles on ColdFusion MX 7 from the Macromedia Developer Center. The first podcast of the series is a reading of Creating Better Forms Faster with ColdFusion MX 7, by Mike Nimer of Macromedia. Later, I as I gain experience with podcasting I'd like to expand the scope by adding interviews and news podcasts that relate to the ColdFusion Community.

To subscribe to the podcasts you can set your podcast-enabled blog aggregator to the ColdFusion Podcast RSS 2.0 feed, where you'll be subscribed only to podcasts but none of the other content on this blog. Alternatively, you could subscribe to the main TalkingTree RSS 2.0 feed which will include all content from this blog in addition to those blogs which contain podcast attachments.

Podcast-enabled blog aggregators include Feed Demon and iPodder. See my earlier blog entry on getting into podcasting for more information about configuring your blog reader for podcasts.

While my podcasting skills still need a lot of tuning, such as trying to speak more naturally and coordinating the music clip volume with the volume of my speaking voice, I think that a human voice is far better than the only other alternative right now for ColdFusion audio content, MXNA Take-away. That site uses text to speech translation software that results in audio that is barely discernable. While it is somewhat tolerable to listen when the speech is common english, as soon it hits technical vocabulary I find it very untolerable and indecipherable. My new podcast series intends to fill the gap with technical content in an understandable human voice.

I'd like to thank the makers of the free audio editing software used to create these podcasts, Audacity.

Getting into podcasting

Not long ago I decided to take the plunge and buy an Apple iPod. It was a great decision and now I love having all my music and photos on one small, portable device that I can take with me walking, running, and driving (while using the iTrip attachment).

One of the best advantages to the iPod is being able to listen to Podcasts. Podcasting is to Radio what blogging is to Publishing. Many individuals and organizations are now providing audio programs as attachments to blog entries. The programs might be a live interview, a tech show, a recorded keynote speech, a short newscast, or even a couple just hanging out.

There are several podcast directories where you can search categories and topics of interest. The two that I use are PodcastAlley and iPodder. PodcastAlley for example even has a Linux podcast category where my favorite there is from Linux Questions.

The convenience of listening to podcasts comes from blog aggregator software that is podcast aware. I use used Feed Demon ($29) from Nick Bradbury, maker of the Top Style CSS editor. With Feed Demon you just configure it to add the podcast channels that interest you and add specific podcasts to queue for download. Feed Demon can then synchronize podcast downloads with your iPod. Another popular podcast aggregator is the freely available iPodder, by Dave Winer and Adam Curry. I've just switched to using iPodder because I find it easier to use than Feed Demon, and I like its scheduling service a lot.

Podcasting was first envisioned by Dave Winer, who added it to the RSS 2.0 specification. In fact, just today I listened to a great IT Conversations podcast interview with Dave Winer where he discusses the origins of RSS, Podcasting, and his vision of how they serve the public by lowering the barriers to publishing so that the little guy can compete toe to toe with large publishers.

If you want to make your own podcasts like I've done, check this engadget blog.

Generating RSS 2.0 in BlogCFC: The Road To PodCasting

BlogCFC currently uses RSS 1.0 in the generated RSS feeds. Most podcasting clients, such as Feed Demon, do not support attachments in RSS 1.0 feeds even though both RSS 1.0 and 2.0 support the enclosure tag. I've recently come up with an idea for a new series of podcasts which I hope to begin producing soon, so rather than fight with RSS 1.0 and podcasting clients, I've added RSS 2.0 support in BlogCFC.

Below is a replacement for BlogCFC 3.5.2 generateRSS() method call which allows generation of either RSS 1.0 or 2.0. Feeds generated with this successfully validate. The RSS 2.0 feed does not yet generate enclosure tags for podcast attachments, a task to be done later. Since the RSS 1.0 feed is well-formed XML with XML directives I have a stylesheet directive for easier viewing, but since RSS 2.0 feed does not have XML directives, I have not included any style information in that feed.

Note that the RSS 2.0 feed includes the optional managingEditor and webMaster elements which require an email address. Remove these two optional elements from the code if you don't want to have your email published in the RSS feed.


Technology Review Article on Employee Blogging

The current edition of M.I.T.'s Technology Review magazine accolades employee blogging by highlighting the PR value to corporations that permit this activity. Read about it here. The print magazine has a supplementary article that extends this web article a bit.

TalkingTree itself is not hosted on the website which hosts many Macromedia employee blogs. This is partly because I like to have full control over the website itself, and I like to have a great deal of personal or non-technology blogs intermixed. The Google Adsense revenue covers hosting costs and then some, so there's really no expense in maintaining my blog individually. See the Credits on the sidebar for a link to my hosting provider in case you're shopping around.

Journey to the center of the iPod vortex

My iPod Photo fits nicely into my Macromedia team jacket.Today, I shoved off into the brave new iPod world as the vortex has finally sucked me in. Today, I am no longer an iPod virgin. My iPod Photo has finally arrived, and the world is good again.

Seriously, I decided it was time to take a look at all that iPod hacking, podcasting, and audio blogcasting going on. I've loaded up my modest mp3 collection of 1900+ songs in about an hour, and the Old 97's are happily humming along in my head right now. Just 8GB so far with plenty of elbow room for my entire digital photo collection.

The iPod phenomenon is really amazing, and I'm surprised that it took me this long to dive in. There are people who use it for just about every purpose under the sun. People who cook by it. People who just want to keep their iPod cozy and warm while still being stylish. Personally, I'd like to catch up with those who want to use it with Linux, and others who want to run Linux on it. So if you see me on the street just tap me on the shoulder coz I might not hear you ;-)

TalkingTree Blog joins up with GalaxyGoo Blog

I've recently had the honor to be invited as a guest blogger on GalaxyGoo which emphasizes the unique nexus of web technology and science. Today I've made my first introductory post to GalaxyGoo Blog. Since I've never had an "About Me" section on, I'm reposting my GalaxyGoo blog entry here to serve just that purpose.

About Me
Hello, my name is Steven Erat and I'm the new kid on the GalaxyGoo block, er..., blog. I've been invited by Kristin Henry of GalaxyGoo to contribute blog entries based on my experience in both scientific research and software development. You might even know me already from my blog on or through my employer Macromedia.
