Integrating Tools in Bluemix DevOps via Open Toolchain
Fri, May 27th 2016 5:26a   Niklas Heidloff
At InterConnect IBM previewed a new set of DevOps functionality which is now available as experimental on Bluemix. Via Toolchains IBM tools and third party tools can be used seamlessly together for the development, deployment and management of Bluemix applications. With toolchains other common non-IBM tools can be integrated nicely in the Bluemix developer experience, for example by providing a single sign on between Bluemix and the various tools. Additionally the tools can interact between each

Running the Spark Recommendations Sample on Bluemix
Wed, May 25th 2016 5:29a   Niklas Heidloff
Apache Spark comes with a set of machine learning samples. One of those sample is a movie recommendation system which makes personalized recommendations based on a technique called Collaborative Filtering. In this article I describe on a high level how this sample works. For more details check out the tutorial from the Berkeley university. The dataset used in that tutorial contains 10 million ratings from 72,000 users on 10,000 movies. The Spark project comes with a synthetic dataset in the same

Discovering Open Data via Analytics Exchange on Bluemix
Wed, May 25th 2016 3:22a   Niklas Heidloff
As I’m trying to learn more about machine learning I spent some time to look for data that I can use. While GitHub is the place to get open source code, there doesn’t seem to be a counterpart for open data. Below are a couple of websites that help finding data. In Bluemix there is an Analytics Exchange which gives you access to free and open data in categories such as economy and business, leisure, transportation, and others. The screenshot shows a sample dataset which contains revie

I’m fascinated by the power of machine learning and I’m trying to learn more about this technology. I’ve started to look into how to use the machine learning library in Spark. The Spark documentation of the spark.ml package explains the main concepts like pipelines and transformers pretty well. There are also a number of good videos on YouTube about machine learning. I’ve used the spark.ml library as opposed to spark.mllib since it’s the recommended approach and it

IBM Bluemix provides a service Predictive Analytics which developers and data scientists can use to build applications that help users to make predictions about the future for different scenarios. Below is a quick introduction of this functionality. Let’s start with a definition of Predictive Analytics from Wikipedia. Predictive analytics encompasses a variety of statistical techniques from predictive modeling, machine learning, and data mining that analyze current and historical facts to

How to build Facebook Chatbots with IBM Watson
Thu, May 12th 2016 4:23a   Niklas Heidloff
I’ve open sourced a simple sample of a chatbot for Facebook that leverages IBM Watson Dialog and IBM Watson Natural Language Classifier for conversations with users. Get the code from GitHub. The GitHub project contains a sample of a Facebook bot built on the Facebook Messenger Platform which is currently available as beta. The sample bot is pretty simple but might people give some ideas how to use cognitive Watson services and how to host the bot on Bluemix. The sample bot shows recent tw

How to invoke OpenWhisk Actions for certain IoT Device Events
Mon, May 9th 2016 3:26a   Niklas Heidloff
Serverless Computing is often useful in event-driven Internet of Things (IoT) scenarios. For example when IoT sensors exceed a certain temperature actions are invoked to fix the issue. OpenWhisk is IBM’s serverless computing offering in Bluemix. In order to implement a use case like above with the experimental OpenWhisk service, at this point you need to deploy a non-serverless application which receives MQTT events from IoT devices and invokes the appropriate OpenWhisk actions. While such

How to use Spring Boot for Serverless Computing
Wed, May 4th 2016 5:49a   Niklas Heidloff
Serverless Computing is a relative new technology which allows developers to build event driven code which scales and for which you only pay the time it’s running. OpenWhisk is IBM’s serverless computing offering hosted on Bluemix. With OpenWhisk developers can implement actions via JavaScript, Swift and Docker. Via Docker other programming languages like Java can be used. This article describes how you can use Spring Boot to develop an action, how to build a Docker image and how to

Useful MQTT Tools for the IBM Watson IoT Platform
Tue, May 3rd 2016 4:00a   Niklas Heidloff
For the development of Internet of Things applications it’s often useful to simulate devices. Below are two options which are easy to use. The instructions describe how to connect to the IBM Watson IoT Platform on Bluemix. In all cases you need to create your own Internet of Things Platform service and create your own device type and device. MQTT Helper With the MQTT Helper application on Bluemix you can connect to a MQTT broker and subscribe and publish to MQTT topics. The trick is to kno
