Data Science for Business by Foster Provost & Tom Fawcett O’Reilly Media

Data Science for Business is a book that makes a phenomenal job teaching the fundamental concepts of Data Science (a.k.a. Data Analysis and Data Mining). Foster Provost and Tom Fawcett explain in plain English, clear examples and beginner-level math the processes surrounding Data Science and the basics of its algorithms.
The authors go over the various steps of the CRISP method using situations found in the real world such as Customer Churn and Online Advertising. The most common data analysis models are reviewed and explained in detail such as Clustering, Decision Trees and Support Vector Machines. Extensive explanation is given to the difference between supervised and unsupervised methods. Even if you use software tools that create those models, this book will help you understand how to use/test them correctly and how to avoid over-fitting.


Multiple examples are given in each chapter and most of the math is visually aided with graphs. The authors explain step by step any equation presented in the book. A notable example is how the authors show how the different parts of the Bayes’ Rule equation come together in chapter 9. There are also special Math-intensive sections that business managers might skip, but software developers and future data scientist need to examine closely.

I would recommend this book to any DBA or Developer looking for an useful introduction to Data Science. For a practical application of the concepts in the book, I recommend Data Analysis Using SQL and Excel by Gordon Linoff after reading Data Science for Business. As a SQL Server DBA, I will apply the concepts I learned with the book to SQL Server Analysis Services.

Power Automate: SFTP action "Test connection failed"

When I added an SFTP create file action to my Power Automate flow ( https://flow.microsoft.com ) , I got the following error in the action step, within the designer: "Test connection failed" To troubleshoot the Power Automate connection, I had to: go the Power Automate portal then "Data"->"Connections"  the sftp connection was there, I clicked on the ellipsis, and entered the connection info It turns out, that screen provides more details about the connection error. In my case, it was complaining that "SSH host key finger-print xxx format is not supported. It must be in 'MD5' format". I had provided the sha fingerprint that WinScp shows. Instead, I needed to use the MD5 version of the fingerprint. To get that, I had to run in command line (I was in a folder that had openssh in it): ssh -o FingerprintHash=md5 mysftpsite.com To get the fingerprint in MD5 format. I took the string (without the "MD5:" part of the string) and put ...

How to create online multiplayer HTML5 games in Contruct2

  Construct2 can use websockets to send and receive messages between games. By using socket-io , we can use a Node.js script as the server and my modification to the socket-io plugin for Construct2 to allow the games to synchronize data between them in real-time. There are two parts to this design: the Node.js server and the Construct2 clients (the games playing). The main part of building an online multiplayer HTML5 game is to plan: how the clients will communicate how often and what to communicate how much of the logic will go into the server and how much to the client. In my sample game, I chose to have each client own a player and have the server just relay messages: Use string messages in the form TypeOfMessage, Parameter1, Paremeter2, Parater3, etc to communicate. Have the clients send their player position about 16 times a second. Whenever their player shoots, the client needs to send a message immediately. Almost all of the game logic will...

How to use Windows SSO with OpenXava

One of the nice things about the .NET web environment is the dead easy way to implement Single Sign On in your web apps through Active Directory authentication. In the Java world there are multiple alternatives to use Windows’ Single Sign On with Java based web apps. One of those alternatives is Waffle . Waffle allows your Java web app to authenticate against Active Directory groups (and users). The only caveat is that your web server needs to be running in Windows, which kind of makes sense. In this article, you will learn the steps required to have your OpenXava web application use Waffle to authenticate your Windows users. The first step is to download Waffle from their site and then copy the JAR files outlined in https://github.com/dblock/waffle/blob/master/Docs/tomcat/TomcatSingleSignOnValve.md to the OpenXava’s tomcat server. In your OpenXava project, create servlets.xml in the Web-inf, containing the following: <!-- the role name (the domain gorup) must be e...
