Working Up

by Dwayne Phillips The user interface and the user experience seem to be based on two, quite simple things. I love to look at the photos on the Analog Dreams posts in tumblr. Those big, beautiful round knobs. I owned a lot of the things shown in the photos, and there was something magical about […]

by Dwayne Phillips The recent rash of misuse and abuse of social media reminds us of that old, boring practice called systems engineering and limiting systems to do only what they are supposed to do. Recent news reports point to all sorts of “misuse” and “abuse” of social media platforms like Facebook and Twitter. These […]

by Dwayne Phillips Which way is your team facing? When? Why? Consider a few options. If we are all facing the same direction…we can’t shake hands, that only happens when we face opposite directions. We can’t see what is sneaking up behind our colleague, again that only happens when we face opposite directions. If we […]

by Dwayne Phillips First you work on a small problem set. Once you learn from that, you expand the problem set. Google recently started hiring speakers with accents to help train its speech recognition software systems. Why didn’t they do this sooner?

by Dwayne Phillips Regardless of what Excel tells us, significant digits (remember that?) tells us otherwise. Recall something called significant digits from high school math?
