Today we talk to our own Drew Rogers about some of the nuanced aspects of Site Reliability Engineering (SRE) and Development Operations (DevOps) within the rapidly evolving domain of sports betting.

In this week’s TechChat, we welcome Keith Gregory, our Cloud & Data Engineering Practice Lead here at Chariot. Keith is a prolific writer both on the Chariot blog as well as on his own, and is a wealth of knowledge on all things AWS. We touch on Redshift execution plans, how to appropriately size Redshift instances, a performance comparison between Amazon Redshift and Athena, and the value of AWS certificates. And if you’re going to the AWS Summit in NYC on Wednesday, July 26th – we’ll be there too! Come say hi.

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?

What's new in Swift 5.9? Variadic generics, macros, observability, interoperability with C++, static linking via mergeable libraries, and more. https://www.hackingwithswift.com/articles/258/whats-new-in-swift-5-9

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. https://developer.apple.com/xcode/swiftdata/

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. https://www.apple.com/apple-vision-pro/

What's new in iOS 17? Voicemail for FaceTime, Assistive Access, NameDrop, SharePlay in CarPlay, NameDrop for sharing contacts, and more: https://www.tomsguide.com/news/ios-17

• 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.
• I sure hope this is legit: Over 500 free programming books on GitHub - we had fun reading this one on writing unmaintainable code.

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.

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.

This week we feature a Philadelphia developer, Andrew Larkin, who works at Comcast as an engineer specializing in accessibility for their various web platforms. He is currently working on an open-sourced Javascript component framework, Xooie, which provides drag and drop, tabbing, and other features and features support for add-ons and additional components.

Comcast is actively looking for external developers to contribute to Xooie and other projects. You can find their open source projects on GitHub at github.com/comcast.

Andrew runs the Philly Accessibility Meetup which discusses how to design and develop technology that can be used by everyone. Their August 5th, 2013 meeting will discuss five simple rules for accessibility.

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

This week we're reviewing our favorite tools, development and otherwise.

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)

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.

Chariot's Steve Smith attended Apple's World-wide developer conference last week, and we sat down today to talk to him about it.

Topics

• WWDC ticket ordering process fun
• New hardware releases
• iOS 7 features
• OS X Mavericks
• His view as a mobile developer of iOS over the years including open source projects, etc...

This week's interview features Fil Maj, of Adobe's PhoneGap project. PhoneGap is a cross-device runtime platform for hosting HTML and Javascript applications on tablets, phones and other hand-held devices. Chariot's consulting practice director Don Coleman joins us as he's worked with Phil on phone gap and plugins, so he lends a hand guiding the conversation. I hope you enjoy this podcast. 

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.

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.

This podcast episode is an interview with three leaders of the 2013 Philadelphia Enterprise Hack-a-thon contest, which is being launched at Philly Emerging Technologies for the Enterprise on April 2-3, 2013. 

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

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

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. 

Rod Johnson is well known for his work creating and leading SpringSource, and the Spring Framework. But did you know he recently started working with TypeSafe organization? He's advising them on their board of directors, and he's working on his own Scala hobby application. He has some views about the language, how to start using it, complexity vs readability, the "No Frameworks" movement, and more. 

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

Advertisement - my co-host for this episode, Michael Pigg, is running TypeSafe's Fast Track to Scala course at our training facility in January 2013. Use the discount code 'techcast' and save $200 on your seat.

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

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. 

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

Enjoy this two-part interview.

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 itextpdf.com.

Rebooting this podcast starting THIS WEEK!  I hope to have one developer news every other week, starting today.

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 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, 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.

We continue our interview with Eric Shamow of Puppet Labs.  Show notes to follow soon, please refer to information from TechCast Episode 65 for now.  

Puppet Labs can be found at www.puppetlabs.com, and they are hosting PuppetConf, a conference on the west coast that is not only about Puppet.

Philly Emerging Technologies Podcast 2011 - #1

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?)

Ross Mason is the founder of Mule, an open source enterprise service bus that implements the Gregor and Hohpe Enterprise Integration Patterns.  Easy to install and configure, Mule does not place heavy demands on developers - there is no required canonical form, services can be expressed in a number of ways, and it supports a wide range of scripting languages, from Groovy to JRuby and beyond.

 

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.

This week's Dev News is brought to you by the letter 'M', as in 'WebM'.  Google has announced that future releases of the Chrome browser will no longer support H.264, instead moving to the new WebM and VP8 codec/format.  So we riff on that for a while.  If you want a really good analysis from people who know Google and video really well, check out the latest episode of This Week in Google from the TWIT network.

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.

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: 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.
