Philly Emerging Technologies Podcast 2011 - #3

How MongoDB Helps Visibiz Tackle Social CRM

Speaker - Mike Brocious - Lead Architect, Visibiz

From the ETE Session Abstract

So you’ve heard about MongoDB and it sounds really sweet (BTW, it is!). Now you’re thinking about using it in your application. We can’t tell you if it’s right for your application, but we can tell you how we’re using it at Visibiz and that might help you with your implementation.

This presentation provides a use case of MongoDB at Visibiz. It first discusses why we chose to use MongoDB as our application’s primary datastore (what were the relevant application requirements and perceived benefits). It then covers how we’re using MongoDB in the application, touching on schema design of the primary collection and listing several secondary uses for it in the architecture. We also touch on lessons learned, as well as pros and cons.

Doing the Mundane a Million Times a Minute

Speaker - Mark Chadwick, Invite Media/Google

From the ETE Session Abstract

When dealing with high-volume distributed systems, even the most mundane tasks can be daunting challenges. This talk describes some of the steps, as well as missteps, made while building such a system. It will work through the discovery of such pain points, as well as describe their resolutions with specific technologies or patterns.

Over the course of three years, Invite Media built a high-volume system for serving online advertisements from the ground up. Some of the more interesting challenges revolved around operating routine services at scale, such as distributing requests, logging diagnostics, and keeping track of simple transactions.

This talk will dive into some of these problems, showing the evolution of simple systems at scale, with a strong bias towards cloud-hosted applications. It will include details about the discovery and resolution of bottlenecks we experienced, as well as specific technologies and pattens discovered in the process.

It may serve as a springboard for ideas when building distributed cloud-based systems, as well as hone a sense of when components may be reaching their tipping point.

Polyglot Persistence for Java Developers

Speaker - Chris Richardson, VMware

From the ETE Session Abstract

Relational databases have long been considered the one true way to persist enterprise data. But today, NoSQL databases are emerging as a viable alternative for many applications. They can simplify the persistence of complex data models and offer significantly better scalability, and performance. But using NoSQL databases is very different than the ACID/SQL/JDBC/JPA world that we have become accustomed to. They have different and unfamiliar APIs and a very different and usually limited transaction model. In this presentation, we describe some popular NoSQL databases – Redis, SimpleDB, MongoDB, and Cassandra. You will learn about each database’s data model and Java API. We describe the benefits and drawbacks with using NoSQL databases. Finally, you will learn how the Spring Data project simplifies the development of Java applications that use NoSQL databases.

ETE 2010 Session #9 - Linda Rising - Deception and Estimation

We are pleased to release this recording of Linda Rising's talk on Deception and Estimation.  This is a one-hour talk, and is a good talk about how we deceive ourselves in a number of ways in life in general, and of course in the estimation process.

From the abstract:

"Cognitive scientists tell us that we are hardwired for deception. It seems we are overly optimistic, and, in fact, we wouldn’t have survived without this trait. With this built-in bias as a starting point, it’s almost impossible for us to estimate accurately.

That doesn’t mean all is lost. We must simply accept that our estimates are best guesses and continually re-evaluate as we go, which is, of course, the agile approach to managing change. Linda Rising has been part of many plan-driven development projects where sincere, honest people with integrity wanted to make the best estimates possible and used many “scientific” approaches to make it happen – all for naught. Re-estimation was regarded as an admission of failure to do the best up-front estimate and resulted in a lot of overhead and meetings to try to “get it right.” Offering examples from ordinary life – especially from the way people eat and drink – Linda demonstrates how hard it is for us to see our poor estimating skills and helps work with the self-deception that is hardwired in all of us."

Thanks to Linda Rising for speaking at ETE 2010 and letting us publish her talk.

ETE 2010 Session #8 - Bonnie Aumann - Are your developers BSing you?

Bonnie Aumann is an agile project manager and customer advocate for Algorithmics. Her ETE 2010 talk is entitled "Are your developers BS'ing you?" In this talk, she tries to cut through the potential blame game and IT culture issues by practicing rapid feedback and response, and Agile techniques.

Her abstract

"A question I’m often asked is how a non-technical manager like me can tell when their software team is pulling one over on them. This seems to be especially true of enterprise managers and points to structural problems with command and control development methodologies. The principlesof whole team interaction and the practices of rapid feedback and response in Agile seem to create an alternative culture in which things "just work."

Explicit tag warning

You'll hear the word "B.S." in long form several times in this talk, so anyone offended by this term should not tune in. However, it's done in context, and is very tasteful.

ETE Thursday Evening Podcast - ETE Podcast #3

We held an open podcast on the evening of April 8th at the happy hour reception of the 2010 Philly Emerging Tech show.  I had invited James Ward and Michael Cote to sit with me, and see what developed.  Well, beyond the happy hour food and beer, which flowed freely, so did the conversation.  Adam Coombs from Infegy sat down with us, and later Ed Burns from Oracle joined the table.

We had a great time with a wide ranging conversation.  I hope you enjoy it.

Standard disclaimer for a live broadcast:  Of course, the opinions expressed are our own, influenced by food and beer, and not those of our employers...




Thanks everyone!

ETE Session 2010 #2 - The Great Web Framework Shootout of 2010

Chariot TechCast ETE Podcast #2 - the Web Framework Shootout of 2010

Warning: NSFW

Our last web framework shootout at ETE was in 2008, and we felt it was high time for another meetup. Since then, Rails and Merb have merged, JSF 2.0 was released, Grails has become more mature, Spring has moved into annotation-driven configuration in a big way, and there are still a ton of choices for an architect to make when choosing a web framework.

This year the shootout is led by Robert Hanson, author of Manning's GWT In Action, who was a speaker on last year's podcast. This is a Not Safe For Work download, as it involves some cursing and stronger statements, but overall it's no worse than you'll hear when meeting up with a few of these guys at a bar.

Slides have been published by Robert on his website.  We will have them soon as well as a large number of slide decks at

Speakers in this shootout include, in no particular order:

  • Chris Richardson of Cloud Foundry/SpringSource/VMware
  • Dan Allen and Lincoln Baxter III of JBoss, a division of RedHat
  • Alex Payne of Twitter
  • David Black of Cyrus
  • Scott Davis of Thirsty Head
  • Yehuda Katz of Engine Yard
  • Jeremey Grelle of SpringSource/VMware
  • Ed Burns of Oracle

All told, we have representatives arguing for Rails, Grails, Seam, CDI, Spring, Spring MVC and JSF, but also discuss JavaScript "we are solving problems from 10 years ago," component abstraction -vs- scripting on the page, the eternal Java versus Ruby debate, and many more.

Music for the podcast was performed by Chariot's Andrew Oswald.

Episode 29 - Manning Authors Forum with Dan Allen, John Resig, David Black

On today's show, we feature the Manning author's Q&A  forum.  Marjan Bace is the co-founder of Manning Publications, which publishes books on a wide variety of technical topics. 

Last year at ETE, Marjan assembled the web framework shootout (if interested...  part 1, part 2).  This year Chariot asked him to assemble an author’s forum, where he takes questions from the audience on writing books for publication.

The panelists are Dan Allen, author of Seam in Action, David Black, author of Ruby for Rails and the upcoming title, The Well-Grounded Rubyist, and John Resig, author of the upcoming Secrets of the Javascript Ninja.

This is a very interesting look at what it takes to write a book, what it demands of you, and what you end up learning in return.  Marjan, Dan, David and John did a great job.

Episode 26 - Andy Hunt on Pragmatic Thinking and Learning

Andy Hunt is co-founder (along with Dave Thomas) of the Pragmatic Programmers.  Their seminal book, The Pragmatic Programmer, gave every developer a nudge, and started their publishing company, The Pragmatic Bookshelf.

Andy's latest book (his seventh) is Pragmatic Thinking and Learning, Refactoring your Wetware.  His keynote at 2009 Philly Emerging Tech covered topics from the book, and was a fantastic walk down memory lane (sorry, couldn't resist).  Seriously, folks, his talk was all about maximizing your ability to learn and retain knowledge.  Here are some great books he mentioned:

  1. Andy Hunt:  Pragmatic Thinking and Learning
  2. Mihaly Csikszent: Flow: The Psychology of Optimal Experience (P.S.) 
  3. Dan Pink: Whole New Mind
  4. Betty Edwards: Drawing on the Right Side of the Brain

You can find Andy's writing on the Pragmatic Bookshelf or on his blog, For a mind map of his key topics, click here.

The second part of the podcast includes audio from the Destruction Zone.  Pictures were posted at our ETE Flickr Group.  The company, Wondergy, allowed us to tear apart old fax machines, printers, computers and cell phones, and worked with Chariot to line up green recyclers to haul it all away.  You'll hear a little audio, although distorted, of the bashing of a copier, as well as an interview with Wondergy's Ken Fink, on how the project came together.

Episode 9 - Web Framework Shootout, Part 2 (Language)

Today we feature the second of a two part session from the 2008 Emerging Technologies for the Enterprise Conference.  The session, entitled "Web Framework Shootout," was assembled and moderated by by Manning co-founder Marjan Bace and was one of the highlights of the conference.  Speakers included Yehuda Katz,  Chad Davis, Max Carlson, Robert Hansen, Bear Bibeault, Chris Richardson, Dan Allen, Emanuel Bernard, Peter Armstrong and Obie Fernandez.  Quite a group!  

I have lightly edited the quiet patches, and edited out one or two questions where people were speaking off mic and nobody responded.  If you hear dropouts, it's because of those reasons, no major content was left out.

This half does contain a few curse words and some heated debates.  There is a very interesting exchange between the Java and Ruby camps.

Episode 8 - Manning Web Framework Shootout at Chariot ETE 2008

Today we feature the first of a two part session from the 2008 Emerging Technologies for the Enterprise Conference.  The session, entitled "Web Framework Shootout," was assembled and moderated by by Manning co-founder Marjan Bace and was one of the highlights of the conference.  Speakers included Yehuda Katz,  Chad Davis, Max Carlson, Robert Hansen, Bear Bibeault, Chris Richardson, Dan Allen, Emanuel Bernard, Peter Armstrong and Obie Fernandez.  Quite a group! 

The show was broken into two parts due to the fact that it ran rather long (over an hour).  I have lightly edited the quiet patches, and edited out one or two questions where people were speaking off mic and nobody responded.  If you hear dropouts, it's because of those reasons, no major content was left out.

The second half promises to be even more entertaining than the first.  I'll publish that segment next week, as we need to beep out a few choice words as the conversation got quite heated.  Enjoy the podcast!
