Demo of setting up and using NFC tags

If you’ve been a bit curious about NFC tags, but you haven’t investigated how to use them, then this blog post is for you. Assuming you have a Windows Phone anyway.

The following presentation is a short demonstration of setting up and using NFC tags on a Nokia Lumia 920 running Windows Phone 8 using the "Nokia Writer Supplies" purchased from

But I also have a short video of me explaining it too – using the same slides.


Excel PowerPivot Example

For the analysts out there who haven’t embraced PowerPivot and Power View in Excel, there is a great tutorial to help you get started: PivotTable data analysis using a Data Model in Excel 2013.

However, if you just want the finished spreadsheet, I have created one that is the result of walking through the tutorial, with only two minor modifications:

  1. Worksheets have names and colors. The black worksheets originated as data from other spreadsheets or databases
  2. The "Count of SalesKey" calculated field has a KPI attached to it and can be seen in the Pivot Table

There are numerous things that should be done to clean up the spreadsheet and make the pivot table more useable, but it’s a good example to start with.

Examples of the Windows 8 ad options available from the Microsoft Advertising SDK

Recently, I have been working on a Windows 8 application to help other Windows 8 developers learn more about the Microsoft Advertising SDK. I’ve learned enough along the way that I have put them into a presentation that contains examples of Windows 8 ads along with a few tips about the Microsoft Advertising SDK:

Time for a personal API

In the books Daemon and Freedom, by Daniel Suarez, society is dividing between people who can wear glasses that are connected to what is essentially a social network. When wearing these glasses and looking at someone, you can see a score for the person, which represents how much others in society respect and value that individual.

Eventually, Klout and Google Glass or Vuzix could provide something similar, or at least start heading in that direction with the Klout Score that measures a person’s overall online influence. So Google Glass developers, please get going with the Klout API so once Google allows facial recognition, we can be one step closer to the world Daniel Suarez envisioned. 

But to take the concept of wearable technology further, I’m waiting for a future where we each have an API. Yes, I want the Brian Groth API so I can build apps based on what I am doing or eating, where I’m going, what I’m seeing/hearing/sensing, and how my body is working. I currently use a Nike+ Fuelband, but I’m considering switching to something like the FitBit Flex now that there is a good FitBit Tracker app for the Windows Phone, which monitors much more for me. 

Is anyone out there building the personal API?
