Thanks to some friends, I started learning to program in high school. Now I am a software engineer. I can sometimes be found running, tending to my garden or playing with my six backyard chooks.
I recently had the chance to add the Intergalactic Transmission exercise to Exercism's C# and Elixir tracks. The goal of the exercise is to practice bit manipulation, by inserting a parity bit after every 7 bits so that each resulting 8-bit byte has ...
The first time I heard of the arc consistency #3 (AC-3) algorithm during a mentoring session on the Zebra Puzzle exercise in Exercism's Elixir track (thanks afraik!). I was avoiding permutating through the combinations and had came up with a solution...
Kernel.update_in makes it easy to update nested structures. For example, let's say we want to change Jack's last name to "Nimble" in the following list of maps: list=[ %{name: %{first: "Jack", last: "Munroe"}, age: 30}, %{name: %{first: "Jill", l...
After setting up my layer indicators, I wanted an easy way to turn on/off and cycle through two RGB matrix effects. The idea was to use plain solid light (RGB_MATRIX_SOLID_COLOR) as a kind of keyboard backlighting and an RGB effect (RGB_MATRIX_CYCLE_...
The plan I planned on having Colemak and numpad layers when I got my first mechanical keyboard - the Keebio Iris (rev 6). The Iris came with built in LEDs for each key and each side had six underglows arranged in two rows of three. I was thinking to ...
The history tracked by Git is a rich source of information on how a project evolved. Every commit captures what changed, when it changed and by whom. In this post, we'll look at ways of searching through the captured information. Search the commit me...
It's generally accepted that we should never simply trust a user's input. Otherwise, we're vulnerable to malicious input (CE-5). For a file upload from a user, it’s common to check their file size or type, especially when restricting them by those tw...
Multiple cursors is handy for quickly changing multiple places at the same time. Sure, there are other ways of doing it (like using find and replace), but sometimes it is easier to "see" the changes as you are making it. This is how to activate it: ...
When I first started with Elixir, I was so used to imperative languages, I would think about how I would code something in one first and convert that to Elixir code. For example, here's a Java switch statement: public static String bottlesPhrase(int ...
