Health Tracker Stats Fun - Jawbone Up24 vs. Nike FuelBand

UP24 vs Nike FuelBand
UP24 vs Nike FuelBand
After being a Nike FuelBand user for several years I’ve got myself an Up24 and decided to compare the data I am getting with both of the devices.  While some of the data, like calorie burn, is subject to interpretation, the other data, such as steps, should have been more or less mechanically calculated.  Surprisingly the data between the two devices had as much as 70% difference with Up24 usually counting more steps and Nike FuelBand generally recording more burnt calories.

Here are a few data points I’ve got over the past week with both devices worn on the same wrist close to 24hours a day:

As you can see there is still no consensus on what constitutes a step and how you calculate calorie expenditure.

Up24 is a newer device and also includes a sleep tracker to maybe has more advanced math, but there is no way for me to claim which one is more accurate.  Both devices accomplished one thing well – giving me instant feedback on when I am active and making me feel good about moving around during the day.

SDET / QA Engineer Interview Checklist

After interviewing and hiring hundreds of engineers over the past 12+  years I have come up with a few checklists.  I wanted to share one of those with you so you could conduct comprehensive interviews of QA Engineers for your team.

I use this checklist when I review incoming resumes and during the interview.  It keeps me from missing areas that ensure a good team and technology fit.  I hope you make good use of them.  If you think there are good questions or topics that I have missed - get in touch with me!

Emotional Intelligence in Software Teams  and Good-bye manual tester, hello crowdsourcing!

Why you should take the software job in San Francisco (or not).

Silicon Valley is an iconic place for technology.  Many people say this is the place for the “best and the brightest.”. Apple, Google, Facebook, Salesforce, Twitter and other top companies draw a lot of talent form all over the world and the largest chunk of VC capital goes to companies in the Bay Area, so it seems like moving here is a no brainer!

The real situation is actually not that simple, I believe there are three scenarios where it makes sense, but in many cases living in the Bay yields disappointing results.  The cost of living, housing situation, homeless catastrophe make places like San Francisco a lot less appealing to a lot of people.  So in what situations does it make sense to move to SF?

Startup founder raising millions There are many places to be a startup founder, but if you are looking to raise capital the largest pool of VC money is in the Bay Area.  There is an established network, events and conferences which give founders an opportunity to pitch more people th…

Sensitivity and Introverts

"Software developers are creative human beings and they need to make sense of unpredictable, turbulent environments"

- Daniel Graziotin, Xiaofeng Wang, Pekka Abrahamsson "Software developers, moods, emotions, and performance" https://arxiv.org/pdf/1405.4422.pdf

Team output can vary dramatically based on the emotional state so neglecting emotions yield to worse performance.  Beyond the pure output no one wants to spend much time in a place where they do not feel good.  It can lead to turnover and engineers applying their talents elsewhere.

There is a stereotype of engineers being highly analytical so in communication with them "facts is all that matters."  This point of view is often not correct.  In "Quiet: The Power of Introverts in a World That Can't Stop Talking" Suan Cain talks about the correlation of introversion, hypersensitivity and involvement in professions that require deep thought, such as software development.
