While working on a project which uses some Google API’s I came across Googles API registry. Under https://www.googleapis.com/discovery/v1/apis/ all API’s for Google services like Google Drive or Gmail are described. More infos can be found at the Google APIs Discovery Service page. From the API registry a client could discover services and automatically build proxy classes and methods based on the provided metadata. Thats what I have done for Pharo Smalltalk. Other companies like Microsoft also provide some form of service discovery for their service API’s (see https://msdn.microsoft.com/en-us/office/office365/api/discovery-service-rest-operations)

If you are using one of FitBit’s fitness tracker devices like the ‘One’ for some time you create a lot of data. When you synchronize your tracker all recorded data is sent to FitBit’s servers. The FitBit portal provides some features for graphically displaying and analyzing your data. It’s also possible to export it manually as CSV to process it further. But what if you want your data locally available without manual export to make own statistics. This is what the ‘fitbit_dumper’ is for.

Update: Since 2016 FitBit uses OAuth2. See this blog post for an update.

See this post for how to install and use it.

I’m always interested in how thing’s work so the following post describes some internals of the X-Z-18 camera.

After weeks of development and several practice tests a summary paper is now available at the IDIRA webpage at www.idira.eu (local copy here)

It describes the findings and experiences of using Google Glass in Crisis & Disaster Management.

As already described in this post I’m testing Google Glass skills being used during disasters by relief field forces. Last week I conduct the second practice test during the IDIRA large scale excercise in Athens hosted by the Helenic Navy at their Skaramangas naval base and conducted as ENCELADUS 2014 exercise.
