Intro to R Data Structures

Hello World,

This article is a video tutorial on introduction to the very bare basics of R.  Its a bit dry, but it is the underlying components of everything covered in the interesting stuff.  Can’t do cool stuff without understanding the basics first.

Part 1: Introduction to Microsoft R Open.

Part 2: Introduction to R Data Structures

Part 3: Data Manipulation with R

Part 4: Beautiful Visualizations with R

IoT Hands on Lab – Azure Portion

Hello World,

For this portion of the HoL, we will be bypassing the Raspberry Pi portion all together and go straight to provisioning Resources and using a local app to simulate the telemetry data. You can alternatively still use a Raspberry Pi as this session was intended, but for time purposes, that can be skipped and the app below can be used for simulating data for a live dashboard.

IoT Hands on Lab

Hello World,

This article is for a hands on lab in IoT I am running.  You will find full documentation at the provided link.  Also, you may run into a scenario in which the MCP 3008 code does not work.  If this is the case, you are likely using an older version of the nugget package which contains it or the new version has not been pushed yet.  You can find the code for the MCP 3008 below.

Here is the link: https://onedrive.live.com/redir?resid=BA8DC4B28555902A!3406&authkey=!AGawE2hfolHvC8s&ithint=file%2cpdf

Data Analytics Architectural Blueprint

Here is a video show casing a sample architecture for doing Data Analytics on Azure.  Enjoy 🙂

Exploratory IoT Analysis with R

Hello World!

These days I need to make videos instead of written articles, so I am going to post a few of those here.

In this video we will do an initial exploratory analysis on a water flow data set that came from a prototype that I built. The prototype consists of a water pump, a valve and a flow meter. The data set exists in SQL Azure. We will use R and R Studio to perform the analysis from an Azure virtual machine.

The code is:

Powering AzureML with Hadoop HBase

Hello World!

Today is a freaking cool day.  Why do you ask?  Because today I am writing an article on how to use two of the coolest freaking big data/data science tools out there together to do epic shit!  Lets start with HBase.  HBase is a way to have a big data solution with query performance at an interactive level.  So many folks are starting to just dump data into HBase.  In the project teddy solution, we are dumping tweets, dialogue and dialogue annotations to power our open domain conversational api.  There really is no other way that is easy to use for us to do this.

The second part of project teddy is to predict based on an incoming conversational component, what sort of response the speaker is attempting to illicit from the teddy bear.  If we power our teddy bear with predictive analytics and big data, this would be perfect.  What better platform to do this quickly and easily than AzureML?

This is a follow up article to this one: http://indiedevspot.com/2015/06/30/writing-tweets-to-hbase-simply/

Accessing Azure for Free with BizSpark

Hello World!

As Azure becomes more and more popular and I encounter more startups, I find myself doing this tutorial all the time and explaining it.  Therefor, I have decided to write a blog article with pictures, to make my life (and yours) easier.

What is BizSpark

BizSpark is the best thing since sliced bread for a startup.  It is literally every development tool and license that Microsoft has to offer for free for commercial purposes for 3 years.  Not only that, but you get $150/month (as of this writing) in Azure for 3 years as well.  As if it couldn’t get any better, you get access to reduced pricing on various products from Microsoft Partners.  Microsoft being such a giant of a company, there are a TON of partners you get special pricing from.  BizSpark also includes product licensing such as just your simple windows licenses, or visual studio licenses, and even SQL Server licenses.  Its everything!  Usually at this point I get the question, so what’s the catch?  There is no catch!  Microsoft wants you to use their tools and be successful with their tools so that when you become a giant company, you are using their tools and not a competitors.  Therefor Microsoft gives these tools to high potential startups for free!  If you think you qualify, apply or come to an event I attend (usually found on the events tab).  You can also ping me on twitter @DavidCrook1988.
