Shout-outs

• Thanks to @tfnico, @lincolnthree, and @mxsb55 for the positive feedback to @techcast on Twitter!

• A great presentation by Jon Sondow on the Netflix Asgard Project- a Grails application server that deploys to AWS. Highlights include:
  • Obama for America used it to keep its sites rolling and alive
  • Used to be Netflix Application Console
  • It is only one of the open source projects on Netflix's GitHub page.
  • Reasons not to just use the AWS console include - you can hide the keys, customize the deployment model, automate workflow, log changes, and more.
  • Also check out youtube.com/theasgardshow - a regular Q&A show they archive on YouTube.
• The Oboe.js Async Ajax Processing Project -Oboe.js's makes web applications faster by wrapping https's request-response model with a progressively streamed interface. It glues a transport that sits somewhere between streaming and downloading onto to a JSON parser that sits somewhere between SAX and DOM. It is small enough to be a micro-library, doesn't have any external dependencies and doesn't care which other libraries you need it to speak to.
• Is Rubinius X going to push Ruby into the fully functional and async I/O future? - Ken found this by reading a tweet : "Erik Meijer @headinthebox - rubini.us/2013/10/15/int…. Just use Scala. You are wasting your life." Ouch. Reading through we found Rubinius X. Very interesting goals for the future of Ruby. Now how will JRuby and MRI deal with the changes?
• Akka persistence is coming.
• We had to peel Sujan off the ceiling on this one... Apple patent on Touch typing / Multi-touch upheld!!! - Um, what??? We just started to LIKE Android phones!
• Python 3.4 is out - Most of the new packages added directly reflect what’s going on in the software dev world right now including Async I/O, but also including data science research APIs in math, statistics, etc...
• The Free Lunch is Over, Again: Distributed Systems presentation by Andry Gross, Principal Architect at Basho (makers of Riak) is a great read about the future of multi-core distributed programming and how it is taking shape right now.

In this podcast, we speak to Magnolia CMS's CTO, Boris Kraft, and to Magnolia engineer Tobias Mattsson.

We first speak with Boris Kraft about the history of Magnolia CMS, and discuss some of the basics of the platform.

Then we interview Tobias, who is the author of the Blossom module. This package provides a Spring MVC web context, which can export content to the CMS from non-traditional sources such as enterprise application data. It uses Spring MVC and annotation-driven classes to expose any data you'd like as content for your project

Tobias is speaking at the upcoming SpringOne/2GX summit in Santa Clara, CA. His topic will be Spring and Web Content Management.

Ken and Joel
(The opinions on this podcast do not represent those of our employer, Chariot Solutions.) 

Joel and Ken talk about:

• JSbin.com and JSFiddle.net - two browser-based tools that make fiddling with Javascript easy and fun
• Trello - a good project-board tool.
• Codiqa - a browser-based mobile IDE for PhoneGap/JQuery Mobile
• Apigee - web service / data service hosting platform.
• Cloudbees - mentioned when talking about hosted development tool suites, includes git/svn, wikis, Jenkins, hosting of the app itself, etc...
• Flowdock - A great project team conversation tool.
• Asana - A todo list tool, getting-things-done-style.
• VIM + CI + Janus = simplicity

Referenced:

• Build a Store Locator App with HTML5, PhoneGap & an API-based Backend (webcast recording)

• They hype it, then they try to kill it - Why Big Data is not truth - just using Big Data techniques doesn’t make it easy to select good data to begin with, or properly apply statistical and scientific methods, but it does make it faster. Joel and I discuss the pros and cons of this article. Speaking of hype, here's the Gartner Research Hype Cycle for ya.
• Joel suggests we may want to eat some Kale - Big Data statistical methods in use to find website issues - Introducing Kale
• Appropos (sic?) of nothing, here's an article that triggered my website security concerns - ever hear of Content Security Policy? Deeper W3C people know about it. It's been implemented in newer versions of Firefox, Chrome, WebKit, Internet Explorer, and other browsers. A draft of version 1.1 has hit, and basically it uses some HTTP headers to turn off/moderate access to embedded scripts and eval() calls. Check it out and add it to your hotlist of security measures.
• Here's an idea: go ahead and try to write an application that reaches over 90% of your smartphone's population. Quick quiz: which one of the major technologies (iOS or Android) would you reach with one version of your software? If you guessed Android, BUZZZT! Maybe not. Turns out iOs is not fragmenting as much as Android is. Guess Apple gets their users to upgrade more. See what Joel and I have to say about it.
• What do you know? Ok, maybe not everything. In fact, definitely not everything. To prove it, Sijin Joseph has put together a web page with a Programmer Competency Matrix. The matrix lays out some areas in which the writer feels a person is not knowledgeable (2^n), has basic knowledge (n^2), has expertise (n), or is a guru (log(n))... I knew we'd get SICP in there somewhere - see the books section.
• We take some time to discuss the article that finally said what we're all thinking. It's time to talk to your Mother in Law - a GigaOm article on LinkedIn endorsements. Wait, this has merit to talk about, because we can claim it's a large amount of data being acquired for use by LinkedIn.
• Netflix is on(to) something. See this fabulous Github IO Page where they list out all of their open-sourced libraries and APIs and use their own movies template to do so. Simply fantastic, and shows their deep commitment to the open source community. One of their most recent contributions is Genie, which manages deploying code to AWS instances and is on Joel's research shortlist.

To leave us feedback on the show, send us a message on Twitter as @techcast, we'd love to hear from you.

Sponsored by the Chariot Education Services Team.

The interviewees are:

• Mike Schellhase  - Director of Field Applications - Bentley Systems 
• Phil Moyer - Managing Director of Technology @ Safeguard Scientific
• Satwik Seshasai - VP of Engineering at NextDocs

When Brian was working at Google as an intern, he was exposed to the Angular framework and learned quite a lot about it. So much in fact, that he developed the AngularJS Batarang, a Chrome debugging tool, and helped to launch their documentation site, also written in Angular.

Lukas has been working for over ten years as an application developer, starting with programming languages such as ActionScript and Flash, and then moving into the Javascript/HTML 5 world. He came upon Angular and also enjoyed working with it, as it just made sense to him.

In this TechCast episode, we'll discuss this framework, which helps developers put together browser-centric HTML and Javascript applications. We'll find out the major components, such as a very easily understood Model View Controller framework, the ViewModel or $scope, and other features such as services and the all-powerful Angular directives.

Topics mentioned include:

• Models, Views, Controller
• The Angular ViewModel
• Scopes
• Services and state
• De-composing pages into multiple controllers
• Yeoman as a build tool for Angular and other platforms
• What are Angular Directives?

Books mentioned:

• Javascript, the Good Parts - Douglas Crockford
• Javacript Patterns
• Javascript Enlightenment

If you want to listen to Rod's history working on Spring, have a listen to episode 74.

Full disclosure: Chariot is a TypeSafe and SpringSource/VMware training partner.

The podcast, then, is broken into two parts - the first part focuses on Rod's history in creating Spring, what makes it compelling, and how it has developed over the years.

The next part, which will appear on TechCast #75, will focus on Scala, a language that has become more popular of late. Rod is currently advising TypeSafe, the sponsors and creators of Scala, and he has been working on a project for several months totally written in the Scala language. 

Disclosure Note - Chariot Solutions is a VMware consulting and value-added training center partner. 

Enjoy this two-part interview.

Best,

We'll hear how Bruno has participated in the PDF specification, has worked with various document management concerns including encryption, forms processing, and long-term archiving of PDF document formats. One very interesting section concerns how he approached licensing, and some of the challenges faced by developers when they are looking at dealing with open-source users versus paying clients, and how that informs the decisions of his company has he moves the library forward.

For information about the iText library, in both the commercial and open-source licensed versions, you can visit itextpdf.com.

This summer has been anything but a vacation, with our training exploding and me spending lots of time in the classroom. I've also penned two updates to Spring Roo in Action, so I've been pretty busy. But I realized we haven't been updating the DevNews, so let's get back to it, shall we?

Well, it's a sad day in Chariot DevNews land. We have to say goodbye to Jason Grittman, who is leaving for a new gig on the west coast. 

Kohsuke discusses the challenges in developing a tool like Jenkins, which changed names after the new owner of Sun, Oracle, decided that it owned the trademark to the Hudson product name. Oracle has contributed Hudson to the Eclipse foundation, and Kohsuke has continued developing Jenkins, sticking to a build per week strategy, conducting all team meetings in an open IRC forum, as well as documenting project status on their website, jenkins-ci.org.

We talk about current efforts, including supporting the plug-in developer community, writing plugins in Ruby, the CloudBees projects he's working on, and more. Thanks again to Kohsuke and Lisa Wells, who lined up the interview.

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.

The Philly Emerging Tech 2011 Conference really knocked me for a loop. What a great show, and so much to process from it too. We'll have content coming in very soon, including screencasts of close to a dozen sessions. Look for announcements here and on our blog soon.

The news this week

So, we're joined this week by @kgriffin - no, not Kathy Griffin, Kevin Griffin (one's British, the other is on the B-List...) Kevin talks to us about iOS 5, what we know, what we can say without getting in big trouble. We also talk about some other things such as the HTML5 web workers API.

Then, I run through some articles, including Ubuntu's shiny new upcoming Unity desktop, the move by Oracle to open source Java even more by handing out Open JDK 7 as the new JDK RI (I know, right?), the VMWare vFabric internal cloud offering (Chariot is a SpringSource/VMware partner but we're including it because we talked about the Cloud Foundry offering, and this is a contrasting offering). We take Ben Darfler's (@bdarfler) audio feedback on the inaccuracies of our recent reporting about Jenkins and Hudson. Thanks to Ben for that feedback note!

Ken & Eric

Chariot integration specialist Rod Biresch and I sat down to chat with Ross recently to talk about Mule, the version 3 release, other related topics.  Chariot is a MuleSoft partner.

More show notes to come.

We also discuss the App Store trend - both of us have used the Apple Mac App Store, and kinda like it, from a consumer perspective.

Big news in JRuby-land, a big release, we have it covered.  Also we talk about a very nice little feature in Spring's property placeholder configuration that enables default values, right in the XML.  And we follow up with a discussion on Rich Hickey's decision to close financial donations to the Clojure project.

Show notes (until it dies) are currently available on delicious.com/developernews/29.  Ken apologizes for the audio quality as he recorded it on his Macbook Air's internal mic, forgetting to bring his mics back from a recording session with 'da band' this weekend.

Have a good week.

Ken & Eric

Show Notes

• MongoDB is built and supported by 10gen
• Information on BSON, a Binary format similar to JSON: http://bsonspec.org/
• Document oriented datastore. Documents are JSON-like. Storage is really BSON, a binary representation of JSON. 
•  Supports ad-hoc querying (like relational)
• Queries are expressed as BSON documents. You can reference deeply nested attributes and there are a robust collection of query operators.
• MongoDB query optimizer is not cost based. MongoDB tries all query plans simultaneously until it one completes, then it terminates the others. It then reuses that plan for the query until it begins to perform poorly
• Document attributes can be indexed similarly to a relational db column.
• Map/reduce is available for more complex data analysis.
• MongoDB has built-in replication and auto-sharding.
• Uses a native binary over-the-wire protocol implemented by various drivers. There are drivers available for many languages/environments.

We have several debates raging in Java-land right now, between the "Spring is a legacy framework" bruhaha, the movement to OpenJDK by IBM, and Apple's deprecation of the OS X JDK.  We attempt to take no side, but we also leave no stone unturned (or is that Tern unstoned) in our efforts to open up debate on these topics...

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.

The watchword this week is Release... Many releases upcoming or out, including FireFox 4 beta/preview 1, Tomcat 7 beta 1, and the upcoming Passenger 3 and GMail with HTML 5.

Links are not being loaded to delicious yet, so here they are in their glory!

• MRHaki on Groovy and clearing time from a date.

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.

Joel and Ken

This is a two-part series.  In the first part, Joel lays out his selection criteria and why he feels most other selection processes are not comprehensive enough for the unique world of open source software.  We then dive into a very informative discussion of open source license models, including the GNU Public License, the Lesser GPL, the Apache license, and variations thereof.

Of course we aren't lawyers, so always consult one before making legal agreements.  But I think if you don't know a GPL from a LGPL, it's definitely worth listening to this talk.

Joel's research, also part of his Master's Thesis in Computer Science, is published in IGI Global's International Journal of Strategic Information Technology and Applications, and is available for $30 online by the publisher.  Disclosure: Joel is not compensated for purchases of this paper.

In part 2, we discuss the other criteria, including code quality, project velocity, pedigree, community, market penetration, and more. We will spend a significant amount of time discussing both static and dynamic analysis of code.  Look for that to be released in a few days.

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 chariotsolutions.com/downloads/presentations.

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.

I first ran into Michael Coté's work back in 2008 when we put together the Chariot Cloud Con East conference. Among the many grandstanding blogs about cloud computing at the time, RedMonk was a place we could go to read about emerging trends, such as Platform as a Service and Software as a Service.

2. The Akka framework homepage is www.akkasource.org (or www.akkasource.com or even www.letitcrash.com)
3. A good blog entry about Akka 
4. The high level overview of Akka from the akkasource site
5. Jonas' home page and the Akka twitter handle

1. Support for anonymous inner classes (before suggested you use closures)
2. Providing an AST Builder, to make it easier to provide AST transformations (such as @Singleton, @Delegate).  AST transformations are compiled into bytecode.

Gaelyk - The Google App Engine framework

1. Groovlets, small groovy web scripts - just write a script!
2. Templates - separate Groovy code from view
3. Injects Google features into scripts, not abstract them too much
4. Sitemesh templating: Guillaume is researching sitemesh integration but likely not including it directly (providing instructions at some point)
5. Question asked by @wmacguyver on what Groovy
   
   1. DataStore was easy to wrap with a thin veneer - is hoping to more groovify and add a DSL around it
   2. Mail - added ONE method to enrich base class to make it eaiser to use from scripting
   3. Route support in 0.32 - was more work but not complex to do...
6. Asked about what projects running in Gaelyk - early days... but check out groovyconsole.appspot.com - a way of executing Groovy code online and sharing snippets.  Written by Guillaume.  Another one out there is a javascript toolkit for writing iphone web apps iui - demo app is built on Gaelyk (no link avaialble)
7. Also hosted on Gaelyk:  Gaelyk project itself
8. Community feedback - will drive some enhancements, obviously Guillaume is very committed to Groovy language too!
9. Users have become contributors - submitting suggested changes / patches, these are very welcome.
10. Future feature:   Querying support on deck potentially for datastore, simple SQL queries don't work on a NO-SQL database.

Question from twitter user @HamletDRC: @techcast Which JDK7 feature will effect Groovy the most: Closures, Jigsaw, or something else? (question for @glaforge)

Java 1.7 Closures -

1. The working document - mentions dynamic interfaces for closures, groovyc compiler could create same interfaces under the hood - could be interoperable POTENTIALLY...
2. Could we pass groovy closures to a java class?  No implementation yet, so we need to see how languages work together...
3. Java closures - cannot access non-final vars, etc... Shouldn't replace Groovy closures with Java closures...

Jigsaw (JDK modularity)

1. Interesting to investigate.  Would be nice to modularize Groovy a bit - maybe pull pieces into modules (groovlets, etc)... OSGi is an option as well, need to evaluate. 

Thanks also to lucaxtex for his tweet: lucastex @glaforge incredible work on #gaelyk UrlRoutes! This is getting sweeter each day :)
