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

Getting started with Spark Machine Learning on Bluemix

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

Getting started with Predictive Analytics on Bluemix
Wed, May 18th 2016 4:06a   Niklas Heidloff
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

In order to learn new technologies I often watch webinars and videos. For Bluemix there pretty good technical webinars with great speakers, mostly from the development teams. Unfortunately they are not that easy to find. So here is a quick overview.

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

Creating Docker Actions with OpenWhisk
Mon, May 2nd 2016 8:32a   Niklas Heidloff
OpenWhisk is an event-driven compute platform that executes code in response to events or direct invocations. The advantage is that you only have to pay for actual usage, not for peaked projections. Developers can implement actions via JavaScript, Swift and, as described below, via Docker. Via Docker other programming languages than JavaScript and Swift can be used. Plus with Docker you can write JavaScript actions that require more Node modules than currently supported by OpenWhisk JavaScript a

How to use API Connect to manage LoopBack APIs
Tue, Apr 26th 2016 6:11a   Niklas Heidloff
LoopBack is a great Node.js framework for building APIs. In the easiest case business objects can be defined declaratively and LoopBack generates REST APIs, the documentation of the APIs, the persistence as well as a client side JavaScript APIs automatically. To take it one step further I used the new Bluemix service API Connect to manage these APIs. As an example I used a simple sample application ‘Approval Requests’ built on the CLEAN stack. The sample is available as open source a
