# Linear Regression from Scratch

Hello World,

So today we will do a quick conversion from mathematical notations of Algebra into a real algorithm that can be executed.  Note we will not be covering gradient descent, but rather only cost functions, errors and execution of these to provide the framework for gradient descent.  Gradient descent has so many flavors that it deserves its own article.

So to the mathematical representation.

# Miami’s top 10 Jail Bookings

Hello World!

So I’ve been working on building some interesting visualizations with open data.  Today I get to show off a really interesting one, not only will we discuss the visualization in depth, but also dive into how I built it.  And here it is, the top 10 bookings in Miami where the legend is in descending order for most common bookings holistically.

# How to work at Microsoft as a Student

Hello World,

This is a question that comes up frequently. How do I get an internship, a job or anything at Microsoft as a student? Well there is a great program, the Microsoft Student Partner program. This is the foot in the door position. Students who do well here are more likely to get a full time job at Microsoft, but also anywhere. I have students who have started their own companies, work at Google, Lockheed Martin as well as Microsoft among several others. It is fairly easy to get into, but once you get in, you better work and treat it like a full time job. You can apply here: www.aka.ms/applyMSP2016

Now beyond this, I have some notes on my experience being a mentor for this program for 2 years.

# Intro to Data Manipulation with R

Hello World,

Here is a recorded version of an in-person training I have been doing.  Enjoy.  I end up coming back to this myself even for reference.

This episode is all about performing data manipulation to derive raw insights from your data using the R programming language.  Data manipulation is the core to anything and everything you do in business intelligence and machine learning.  This episode sets the base for all R based intelligence sessions from here on out.

Part 4: Beautiful Visualizations with R

# Testing charts

Hello All,

So I have been on a quest to find a great language/set of tools for data exploration and visualization. But not only that, deliver to modern app platforms. You can see I have been very active with R lately, as I liked those visualizations, but not the F# ones. But then along came this Xplot thing from fslab.org.  Whats interesting about this is that I can write F# code to generate interactive charts similiar to how I did in R.  The big difference though is that I can deliver those to a production environment.  In R, you have shiny, which is “free”, until you want to run real workloads with security etc, then its \$10k.  That sucks, I just have a simple blog.

# 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

# Introduction to Microsoft R Open

Hello World!

Ever wonder the difference between R and Microsoft R?  Considering learning R as a programming language?  You should probably watch this video.  It is the first in a 4 part series to give you the jump start you need to becoming a professional data scientist with R.

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

# Building Video Games

Hello World,

Due to my time in the games industry, I still occasionally receive questions around it. Today I received an email from a college student with some questions I feel are more broadly applicable and am therefor writing an article which can be shared to that broader audience.

# 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.
