This content is moving... The new home of our emerging technology podcasts and screencasts is Chariot Emerging Tech. The current feed will be retired soon.

Our first podcast from Philadelphia Emerging Technologies for the Enterprise is our Javascript frameworks panel. Led by Robert Hansen, author of GWT in Action and host of our prior Web Framework shootout in 2011, it includes developers who contribute to Meteor, Backbone, Ember and AngularJS, four Javascript frameworks that cover the gamut between all-in one platforms to comprehensive client-tier frameworks to strongly focused and less-comprehensive and more configurable ones.

Panel members

Robert Hansen - moderator
Avital Oliver - Meteor Development group, core developer
Tim Branyan - Matchbox - Backbone contributor
Yehuda Katz - creator of Ember, Rails Ruby and other standards projects contributor
Brian Ford - AngularJS Core Team / Google / co-author AngularJS in Action
Lukas Ruebbelke - Senior Engineer WebFilings - co-author of AngularJS in Action

Sponsored by the Chariot Education Services Team.

Joel Confino is a long-time consultant at Chariot Solutions. He has spent the last four years working with a large enterprise, here named ABC Corporation, rolling out a new development platform and build process. Joel was one of two speakers at our event, which also included Sonatype's Jason Van Zyl. Joel's focus was building in competitive advantage by choosing to implement continuous integration tools such as Maven, Nexus, Jenkins, and Sonar.

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.

Today's conference session is a talk from this week's Mobile Application Developer seminar series, held by Chariot Solutions, in Philadelphia. 

The talk, "State of the Art for Mobile Application Development", was given by Chariot's Don Coleman, who develops both enterprise and mobile applications in a variety of platforms and languages.  In this talk, he surveys the current landscape of APIs and platforms, and gives his perspective on where things are today, and where they may be moving to in the future.

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.
