Hey <<First Name>>,

I’m still basking in the afterglow of my recent launch of Secure Meteor, but I still managed to find the time to get some programming in.

While working on last year’s Advent of Code challenges, I learned that J natively supports a “rational number” type and filed that knowledge away for later use. I revisited that piece of information last week and attempted to write an infinite-precision Mandelbrot fractal renderer using rational numbers to represent components of complex numbers.

While my infinite-prevision renderer was unusably slow, I did stumble across a much better way to implement a Mandelbrot equation iterator in J.

I think the new solution off some of the beauties of the language and really proved to me that the best way to learn J is to stop fighting against its peculiar way of doing things and just like, relax man…

I’ve also been playing around with Dave Green’s ridiculously cool Cubehelix coloring algorithm. Check out this Codepen I threw together that generates random color palettes.

Lastly, I’m unbelievably excited about Chris McCord’s recent release of Phoenix LiveView. Some of the examples being pumped out by the Elixir community are giving me euphoric flashbacks to my early Meteor days. I’m eager to play with it sometime this week.

So, what have you been up to this week?
