I keep a lot of information about my house – I have had sensors and recording units in various parts of my house years, recording info through a variety of different devices.
Over the years I’ve built a number of different solutions for storing and displaying the information, and when the opportunity came up to write about a database built specifically for recording this information I jumped at the change, and this is what I came up with:
As home automation increases, so does the number of sensors recording statistics and information needed to feed that data. Using the Time Series Database in BlueMix makes it easy to record the time-logged data and query and report on it. In this tutorial, we’ll examine how to create, store, and, ultimately, report on information by using the Time Series Database. We’ll also use the database to correlate data points across multiple sensors to track the effectiveness of heating systems in a multi-zone house.

Part two of my introduction to programming Erlang is available on IBM developerWorks:
Erlang is a multi-purpose programming language that is primarily used for developing concurrent and distributed systems. Part 1 of this series introduced Erlang and how its functional programming style compares with other programming paradigms such as imperative, procedural, and object-oriented programming. In Part 2 you will use some of the advanced features and functionality, starting with basic functions and moving on to concurrent programming, processes, and messaging. These work together to support distributed programming, a powerful feature of Erlang.

I have a new article on programming in Erlang available on IBM developerWorks:
Erlang is a multi-purpose programming language used primarily for developing concurrent and distributed systems. It began as a proprietary programming language used by Ericsson for telephony and communications applications. Released as open source in 1998, Erlang has become more popular in recent years thanks to its use in high profile projects, such as the Facebook chat system, and in innovative open source projects, such as the CouchDB document-oriented database management system. In this article, you will learn about Erlang, and how its functional programming style compares with other programming paradigms such as imperative, procedural and object-oriented programming. You will learn how to create your first program, a Fibonacci recursive function. Next, you will go through the basics of the Erlang language, which can be difficult at first for those used to C, C++, Java™, and Python.
