Retail is one of the most important business domains for data science and data mining applications because of its prolific data and numerous optimization problems such as optimal prices, discounts, recommendations, and stock levels that can be solved using data analysis methods. The rise of omni-channel retail that integrates marketing, customer relationship management, and inventory management across all online and offline channels has produced a plethora of correlated data which increases both

I have a few popular Oauth related posts on my blog. I have one pertaining to Oauth 1.0a , and I have one on the topic of Oauth 2.0 for use in mobile application development. However, I get a lot of requests to show how to accomplish an Oauth 2.0 connection in a web browser using only JavaScript and AngularJS. We’re going to better explore the process flow behind Oauth 2.0 to establish a secure connection with a provider of our choice.

I'm excited to announce that I've joined SpeedCurve! When SpeedCurve was just a twinkle in Mark's eye, he contacted me about the concept and I encouraged him that a commercial version of WebPageTest was needed. When I saw the early versions of SpeedCurve, I was blown away. Mark presents traditional performance data in a way that is more compelling, revealing his strong design background.

As our understanding of performance on the web improves, we are starting to shift from the traditional metrics we’ve focused on. Things like load time and page weight are rightfully being given less focus as we move to more mature metrics like SpeedIndex that provide a better understanding of perceived performance. But that doesn’t mean we can dismiss page weight altogether.

I've published drafts of the introduction and first 4 chapters of my book, Activist Investing in Strategic Software. I still have some citations to finalize, several visuals to integrate and a lot of editing to do. But the foundation is there. A sample of the book (currently, just the introduction) is available on from the site. Here's an excerpt from Chapter 1, Why Governance Matters. * * * That there are abundant examples of bad governance but few examples of good ones comes as no surprise.

Have you ever built an app that has heavy content that might need to one day be printed to a PDF or to paper? Maybe you’re building the next great email or news app, both of which have an expectation that you should be able to print what you’re reading. Both iOS and Android have printing functionality. We are using Ionic Framework , and lucky for us, printing to either of these platforms couldn’t be easier when we use the Apache Cordova Printer Plugin by Sebastian Katzer.

'Grapevine was one of the first systems designed to be fully distributed. It was built at the famous Xerox PARC (Palo Alto Research Center) Computer Science Laboratory as an exercise in discovering what is needed as the fundamental building blocks of a distributed system; messaging, naming, discovery, location, routing, authentication, encryption, replication, etc.

Thousand of AWS customers and partners will be in Austin for SXSW Interactive and given the free flowing networking it is a very important feedback opportunity for us.

As you all know security, privacy, and protection of our customer’s data is our number one priority and as such we work very closely with regulators to ensure that customers can be assured that they are getting the right protections when processing and storing data in the AWS. I am especially pleased that the group of European Union (EU) data protection authorities known as the Article 29 Working Party has approved the AWS Data Processing Agreement (DPA), assuring customers that it meets the hig

I recently started making an application with Ionic Framework that made heavy use of images both remotely and locally. During this time, my goal was to present the images in a grid that looks good for all device sizes and orientations. One might think this would be an easy task because Ionic offers both grids and a responsive class, however, trivial was far from the case.

Have you ever needed to come up with a random string of characters say for a password? Maybe you’re looking for a random string of characters for an oauth 1.0 nonce. Maybe you’re in a job interview and you’re asked to generate a random alpha numeric string. Whatever the case, we’re going to look at generating a random string of characters of any given length using JavaScript.

Since writing my two tutorials regarding using SQLite in Ionic Framework and shipping an app with a pre-populated database , I’ve received many requests for a tutorial for making a full blown app. I listen to my readers, so I figured what better way to show such an example, than to create a todo-list type application. In this tutorial, I hope to accomplish the following: Shipping a pre-populated / pre-filled SQLite database.

To continue on my trend of Firebase and Ionic Framework based tutorials, I thought, wouldn’t it be cool to sign into your Firebase application using a social media account such as Facebook? Out of the box Firebase and AngularFire offer some nifty methods for authentication, however they don’t work quite as expected when it comes to mobile hybrid applications and I’ll explain why.

Anyone who knows how to program can probably solve a mathematical equation such as 5 + 3 * 6 - ( 5 / 3 ) + 7 , but how might you get a computer to understand the appropriate order of operations? The equation I listed is in a format known as Infix Notation. Infix Notation via Wikipedia : Infix notation is the notation commonly used in arithmetical and logical formulae and statements.

The Node Package Manager (NPM), is becoming a major go-to resource for all development software and libraries. It is easy to use and covers a lot of ground. If you’re anything like me you’re going to have more than twenty global packages installed on your machine through NPM, but how do you go about tracking whether or not any of them have become outdated?
