  • Deriving a New Formula

    Way back in the day, I was fairly obsessed with triangles. I really enjoyed my trigonometry class in high school. In addition to being interesting, it was the impetus for me learning to code. I got a little tired of doing all the myriad of sin() and cos() and tan() functions to solve the triangles needed by my homework, so I decided to write an app for my TI-83+ graphing calculator to do it all for me. The app would ask you for the three things you knew about the triangle (almost any combination of sides or angles) and give you back all the rest of the information (including perimeter and area). I still have that source code.

I thought that was a great idea, so here we are!

  • If iPads were meant for kids

    I bought my kids (6 & 8) their own iPads last fall. I’m nice, and I’m fortunate to be able to afford it. However, I’ve come to realize that despite my attempts to spoil my kids, these iPads (and all iOS devices in general) are not meant for kids.

    Recently Quinn, an engineer on the Developer Technical Support team at Apple, posted a request for feedback on Apple’s networking APIs. Here are his questions and my answers:
