A/B Testing and 3D Printing

It is August and the doldrums as far as Engineering and Consulting practices are concerned and that is GREAT.  There is time to take on all the more serious projects that I am too busy with at other times.

I setup my new-to-me 3D printer: 3Dsystems Cube 3 and tested it by printing a new key cap for my keyboard.

Then I got down to serious A/B testing with the setup seen here

I received a Bean Box from Seattle Roasters and I needed to improve the pour from the machine on the left which doesn’t have the same pressure mechanism as the old Capresso on the right (which is used at work).

Pretty snazzy and useful for a second object print.

Being A … After 40

Adrian Kosmaczewski gave a talk on Being a Developer After 40 at App Builders Switzerland on April 25th, 2016.  If you click through to his article you will find his slides which are available on SpeakerDeck and at the bottom of his article. The video of the session is available in YouTube. This article has been printed in the June 2016 edition of Hacker Bits.

I am saving bits of it for me to focus on; however, the entire article was well worth the time to think over what he had to say, check it out!
