Found – Apple watch uses green LEDs to measure your heart rate


I missed this post a year ago describing how the Apple watch has both green and red LEDs to measure your heart rate on your wrist.

Really neat way to show visualizations of cause of death, baby names and how people spend their day


This article captures how to show data interactively and fun way.

He explains how to build such a visual also.

Contact management in 2016


I have all my contacts on Yahoo and have for years. Yahoo’s features have worked for me however the service has become dated and does not have some of the more modern look and feel.

However I use the contact features of Apple IOS, mainly facetime and texting string and now photos for contact.

So I’m studying how to maintain these two systems and am considering converting my Yahoo contacts to Apple IOS contacts. To take all my requirements into consideration will be a longer due diligence process some of which I’ll record here.

This article says how to use google contacts as you can manage it on IOS and Android smartphones.

ElasticSearch as used by Hotelstonight



I think I understand the value of elastic search better after looking at the slides on this presentation:


It is the right high level view so I think I can finally see how elastic search would work as a solution in Healthcare.


Atrial Fibrillation detection defined


This post on 9to5mac has this response which explains a lot!

Atrial fibrillation with a rapid ventricular response is not appropriately measured/monitored with a photoplethysmogram. The nature of atrial fibrillation is that the beats are irregular, and with a very fast rate the individual beats will not reliably perfuse the extremities, at least not to a level that can be consistently detected by an external device. It is a case of having the wrong tool for the job, rather than the tool functioning incorrectly. The best tool for the job is an implantable loop recorder–this measures continuous cardiac electrical activity (ECG) and will readily detect A-fib with RVR.

Things in 2015 that show just how far we’ve come technology wise


Here is my list of technologies that had the most influence in 2015

  1. encryption on a smart phone.
  2. voice recognition in Cortana, Google voice and Siri. Siri is finally understanding me much better.
  3. google photos metadata i.e. person, place and object recognition.

Honorable mention:

  1. Containerization manifest with Docker. Amazing technology.

Removing all the BS, the essence of Modern encryption and how about, as a solution, let’s outlaw math


Why is encryption effective? Keep it simple.

Well the roots of encryption is math and in particular prime numbers. Go here for a great, simple explanation of the bases of modern cryptography. Let’s outlaw math.

So now we understand encryption, how does Apple and the iPhone, well really IOS handle encryption? Ah, here is where IOS leaps ahead of Android. These are smart people at Apple and they describe how IOS is secure. IOS Security Guide.

When I find or someone can point me to the Android security guide, I’ll post it here.

Found it, the Android security page. Android Security Guide
