We're excited to have Michael Hulet back to the show. Michael is an iOS expert here at Chariot, and we talk candidly about some of the major announcements that came out of WWDC 2023: SwiftUI, SwiftData, the Apple Vision Pro, iPadOS, and.... the Kool-Aid guy?

Show Notes:
Enjoyed Michael's insights? Don't miss his episode about developing accessibly for mobile:

What's new in Swift 5.9? Variadic generics, macros, observability, interoperability with C++, static linking via mergeable libraries, and more.

SwiftData, a modern, macro-based replacement for Core Data (well, it technically wraps Core Data). Makes it easy to persist data using declarative code, can query and filter data using regular Swift code, and integrates seamlessly with SwiftUI.

Apple Vision Pro: a $3800 pair of ski goggles, or "AirPods for the eyes." We kid, kind of, but we're excited to see where this gadget goes.

What's new in iOS 17? Voicemail for FaceTime, Assistive Access, NameDrop, SharePlay in CarPlay, NameDrop for sharing contacts, and more:

Here's how to run Apple OS X Sonoma Developer Beta on UTM from OS X Ventura, written by Ken Rimple:

Susan McPherson has always had a foot in the non-profit world. With a number of years in a board position on Business Council for Peace, and working with Fabian Cousteau to help people to understand the importance of the oceans, but at Fenton, she was able to start helping corporations use tools that NGOs normally bring to advance the public good.

Our interview begins by defining Corporate Social Responsibility, discussing how technology companies are adopting CSR missions to both improve the environment and their bottom lines. We discuss B Corporations, how companies best implement CSR plans, and avoiding greenwashing by being authentic in your goals.

This week - it's Not about Furby, but about the new Apple iPhones. Your hosts, Ken Rimple, Sujan Kapadia and Joel Confino talk about whether they'd go out and buy one, whether they still display the same appeal, and what's under the surface that could be a potential game changer.

We also cover former Charioteer Brian O'Niell's Long Tail Treasure trove, a great JavaZone talk about some fantastic APIs he's used, Spring's new YARN framework for Hadoop 2.0, the Go language, $100 tablets, and more robot overlords.

The links

  • Want a quick way to create a fast, Netty-based server? Check out this GitHub project, RestExpress
  • And more about Netty... Why Netty? Java's Native IO (nio) of course!
  • Hadoop 2.0 introduces YARN. But how to ball up some YARN? Let's use Spring YARN for developing Hadoop YARN applications
  • Before he went off to the west coast to work for NING and GroupOn, Brian McCallister worked at Chariot. He has a great JavaZone slide deck - The Long Tail Treasure Trove- a set of APIs he's used on various projects. Joel talks about:
      • Xbean Finder - Find all of the classes in a jar that have your custom annotation. It uses ASM for speed and security.
      • Airline - a Java annotation-based framework for parsing Git like command line structures
      • JAnsi - Eliminate boring console output from your Java apps, let’s you do cools, etc...
      • Netflix Feign - Easily write Java clients that consume Web Services (alternative to Jersey, etc)
      • Jackson module afterburner - a Jackson module that uses bytecode generation to further speed up data binding (+30-40% throughput for serialization, deserialization)

    (pause for cheesy marketing) - And if you act now, much, much more!!!

  • IP Law and FOSS - one can help the other - an interesting take on how copyright, patents, trademark laws can intersect with open source projects.

Magnolia CMS is a content management system written in Java that has a long history. Created more than a decade ago, it has evolved into a platform with a significant user base and a large number of third-party extensions that the team dubs 'modules'.

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.

It's the big return of the regular DevNews this week. My co-host Joel Confino and I discuss lots of big data stuff, including:

  • 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.

Lukas Ruebbelke and Brian Ford, both speaking at Philly Emerging Tech this April, are co-authors of the forthcoming Manning book, AngularJS in Action. They are currently preparing for their first Manning Early Access release, or MEAP.

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

This interview is a walk through the lead up to and the creation of the Spring Framework with no founder Rod Johnson. Recently, Rod left the company sponsoring Spring, VMware Corporation, and joined up as a board member of TypeSafe to advise them on the future of Scala and other projects.

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.

This techcast episode features the open source PDF API developer Bruno Lowagie. His iText library has been used by many Java developers. One of the earier open-source Java APIs, iText was originally written to provide PDF version 1.3-compliant output. This was not the first API that Bruno created to handle PDF, as we'll hear in the interview, and also not the first to be open-sourced.

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

Kohsuke Kawaguchi (@kohsukekawa) is the creator of Jenkins, a continuous integration tool he wrote a number of years ago as a way to verify that he checked in his files and didn't affect his multi-developer build. It is safe to say that Kohsuke wasn't the only one with that problem. A huge hit, the Jenkins CI server, which at the time was known as Hudson, reached a wide adoption level, with people installing it officially and even under their desktops in many IT development shops. 

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,

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.

What a couple of weeks!

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!

Davis Frank is an agile software engineer who created and contributes to the  open source Jasmine javascript testing framework.  He created the project to help him test applications for the former Palm, now HP webOS mobile application platform, which is written in native Javascript.   Pivotal has a number of projects related to jasmine on github, including the port of Jasmine to the HP WebOS framework, which he also created.

He is speaking at the Philadelphia Emerging Technologies for the Enterprise conference next week, and his talk, Practical Jasmine, will start with a 10 minute quick demo, then dive into real tips on how to best use (see how I didn't use utilize?) the framework.  We spoke last week about a number of topics, including how Javascript is just a bit different than other languages, how the current testing tools didn't meet the needs of Pivotal when they were developing applications on the HP WebOS mobile platform, and about where to go to see well-written Jasmine tests (how about the Jasmine source code itself?)

Eric Snyder discusses MongoDB, a document-oriented NoSQL database.

Show Notes

  • MongoDB is built and supported by 10gen
  • Information on BSON, a Binary format similar to JSON:
  • 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.
