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

Developing OpenWhisk Actions via the new Web Editor
Mon, Apr 25th 2016 6:02a   Niklas Heidloff
In addition to Cloud Foundry, Docker and Virtual Maschines Bluemix provides a fourth compute option OpenWhisk. OpenWhisk is an event-driven compute platform that executes code in response to events or direct invocations without having to maintain servers. The advantage is that you only have to pay for actual usage, not for peaked projections. As I blogged about earlier you can write OpenWhisk actions in JavaScript and Swift. The actions can be deployed via CLI (command line interface) and now al

This week my colleagues David Barnes, Ryan Baxter, James Thomas, Thomas Bück, Timo Roeseler and I attended JAX in Mainz/Germany which was attended by 2000 people, mostly Java developers. There was a lot of interest in Bluemix and we enjoyed the discussions with developers. Below are some pictures from our booth, our sessions and prize draws. The team from left to right: Ryan, James, David, Thomas, Niklas David Barnes in his keynote about the next generation of software developers and drones:

How to get started with Machine Learning on Bluemix
Fri, Apr 15th 2016 10:22a   Niklas Heidloff
There is a lot of talk about artificial intelligence (AI) these days, especially since Google’s AlphaGo beat a Go world champion. Companies like IBM are using this technology already in a number of products. For example on Bluemix developers can easily consume cognitive Watson services like speech or image recognition that use machine and deep learning under the cover. While these Watson services are very easy to use for developers, sometimes you want to use machine learning for other scen

Driving Cars autonomously with IBM Bluemix
Mon, Apr 11th 2016 5:27a   Niklas Heidloff
At JavaLand we presented how to steer Anki Overdrive cars with IBM Bluemix via speech and gesture recognition. Since the cars send their position data to the cloud we could also demonstrate a simple version of collision prevention. The demo is available as open source and I documented it in a series of blog entries (see below). My colleague David Barnes interviewed me and created the video Driving Cars autonomously with IBM Bluemix. Thanks a lot, David! Here is the high level architecture with

Measuring Heart Rate with Wireless Earphones and Bluemix
Thu, Apr 7th 2016 10:06a   Niklas Heidloff
The Dash from Bragi are wireless smart earphones with a lot of sensors in them. Below is a quick example how to get data from the heart rate sensor and send it to IBM Bluemix. This functionality could be used, for example, to track health of factory workers or patients in hospitals. I open sourced the code on GitHub. At this point the controller is running on a MacBook (when the device will expose more sensor data, I’d like to provide a sample mobile app). The controller talks to The Dash

Meet Bluemix at JAX 2016
Wed, Apr 6th 2016 4:33a   Niklas Heidloff
From April 19th until 21st my colleagues David Barnes, Ryan Baxter, James Thomas and I will attend JAX in Mainz/Germany to present IBM Bluemix and to talk with developers. JAX is a developer conference with around 2000 attendees with a focus on Java, architecture and software innovation. I attended JAX and W-JAX last year and based on my positive experience I’m sure it will be a great conference again. David, Ryan, Thomas and I will give sessions related to the cloud, IoT and Docker.

My Thoughts on the Next Generation of IBM Domino App Dev
Tue, Apr 5th 2016 6:26a   Niklas Heidloff
Before I started to work on Bluemix I had worked 15 years in the IBM Collaboration Solutions space, especially on application development. Below are my personal thoughts on how app dev in IBM Domino could evolve, both on-premises and in the cloud. App Dev Models in Domino Since Domino has been around for a long time the app dev capabilities have grown. At this point there are developers who build rich client applications via forms and views, there are developers who use Domino pass through HTML,
