Webinar Replay: Reactive data-pipelines with Spring XD and Kafka

Speakers: Marius Bogoevici & Mark Pollack

Slides: https://speakerdeck.com/mbogoevici/reactive-data-pipelines-with-spring-xd-and-kafka

In the recent years, drastic increases in data volume as well as a greater demand for low latency have led to a radical shift in business requirements and application development methods. In response to these demands, frameworks such as RxJava and high throughput messaging systems such as Kafka have emerged as key building blocks. However, integrating technologies is never easy and Spring XD provides a solution. Through its development model and runtime, Spring XD makes it easy to develop highly scalable data pipelines, and lets you focus on writing and testing business logic vs. integrating and scaling a big data stack. Come and see how easy this can be in this webinar, where we will demonstrate how to build highly scalable data pipelines with RxJava and Kafka, using Spring XD as a platform.

SpringOne2GX 2014 Replay: Philosophical Architecture in Grails

Recorded at SpringOne2GX 2014.

Speaker: David Dawson, Simplicity Itself

G&G Special Topics

Slides: http://www.slideshare.net/SpringCentral/s2gx-philosophicalarchitecture

Software development is hard. Life is hard. We try to keep up with a changing world, and it's hard. Where though, does the problem lie? In this talk, David, CEO at Simplicity Itself, will describe a different way of approaching the problem of software development, a different way of trying to keep up with a changing world. This is not a soft talk, all opinions are backed up by cold hard code in a running Grails application, showing how a change in the way you think can radically change your software.

SpringOne2GX 2014 Replay: Groovy Vampires: Combining Groovy, REST, NoSQL, and more

Recorded at SpringOne2GX 2014.

Speaker: Kenneth Kousen

G&G Special Topics

Slides: http://www.slideshare.net/SpringCentral/groovy-vampires

If a book as horrible as Twilight can sell millions of copies and be made into an even worse movie, how many copies can a book with Groovy vampires sell? (Spoiler: Not as many.) Yes, this topic may be silly, but the technologies used (Groovy, Ratpack, MongoDB, Grails, REST) are (un)deadly serious.

SpringOne2GX 2014 Replay: Grails Plugin Testing Strategies

Recorded at SpringOne2GX 2014.

Speaker: Baruch Sadogursky, JFrog

Slides: No slides, Baruch is 100% demo, baby

G&G Special Topics

Maintaining Grails plugins can be a real challenge given the high expectations and demands. Apart from supporting many users, you're tasked with making sure that the plugin is compatible with a range of Grails versions - both old and new. Your plugin must also be compatible with multiple development environments (OSs, SDKs, etc,) and play nice with the wealth of other plugins that exist in the ecosystem. How can we make sure that all these high standards are met? Testing, and lot's of it!

Testing an Angular Application: Angular JS and Spring Security Part VIII

In this article we continue our discussion of how to use Spring Security with Angular JS in a “single page application”. Here we show how to write and run unit tests for the client-side code using the Javascript test framework Jasmine. This is the eighth in a series of articles, and you can catch up on the basic building blocks of the application or build it from scratch by reading the first article, or you can just go straight to the source code in Github (the same source code as Part I, but with tests now added). This article actually has very little code using Spring or Spring Security, but it covers the client-side testing in a way that might not be so easy to find in the usual Javascript community resources, and one which we feel will be comfortable for the majority of Spring users.

Spring Social 1.1.1 Released

Dear Spring Community,

I’m pleased to announce the availability of Spring Social 1.1.1.RELEASE. This is a maintenance release, addressing a handful of bugs and introducing a few minor improvements. View the release notes for full details.

Compatibility note: In order to fix a serialization issue when using ProviderSignInUtils, a minor breaking change was necessary. ProviderSignInAttempt no longer carries its own ConnectionFactoryLocator and UsersConnectionRepository. Those must now be passed in as parameters when instantiating ProviderSignInUtils.
