Final project time, at long last it’s time to flex new React knowledge by putting together a full-stack web application that marries a React front end with Redux state management to a backend Ruby on Rails API, with a SQL database. So how about a few more beats from the home stretch? First I’ll break down how the Rerun gem makes tweaking a Rails development server a bit faster. Followed up with how to use the built in environment key management system in Rails, can help you encode private keys, without needing a third party gem like Figaro. …


JavaScript promises, or ratherPromisesare objects that function as placeholders for values that are not necessarily known at the given moment a line of code is executed. They are proxies for a value, that isn’t necessarily known or defined at that moment. They allow us to build handlers that asynchronously wait for an action’s eventual value should it fail or succeed.

To use a financial analogy, a JS promise is like a check or bearer bond. It’s not actually a sum of cash in hand, but at some point in the future, they can be processed and redeemed as such. In…


Flatiron Project number four — finally! Catch the repo here.

How many projects have I finished now? Well…

There are four projects

Lets rewind back to the beginning though. Dcode has a great supplement to the Flatiron instruction set with a fantastic tutorial https://youtu.be/6BozpmSjk-Y Essentially a one-stop run through of using Node JS and using it’s Express library to serve up a pretty nifty single-page application (SPA) framework. In the interests of meeting our requested minimum viable product however, I realized I’d be delving into coding material beyond our requisite code-base and would probably not be eligible for submission to…


Foreword: To C.H. Garza, my grandfather. The first engineer I ever met, and who helped inspire me to put hand to the world and shape it for the better.

Well if you know me, you’ll know this month has been particularly trying even in the middle of the pandemic. But basically this little post is about how I built an application in Rails that uses the RSpotify gem to gameify users’ Spotify playlists.

Well tons of people have written about building an application that uses OmniAuth. Many of them were fantastically useful while building Greatest Hits. However few authors, if…


It’s the contrast that hits hardest. The stark variance as to how one actually perceives the two projects. It has made writing — although ‘building’ is perhaps the more accurate term, working system in Ruby and Sinatra to be fantastically different experience versus the command line interface project from only a month ago. Sorry, dear reader this absurd stream of consciousness gushed forth making many assumptions. So lets rewind a bit, and start from the first moment, the initial spark of inspiration for this perhaps rudimentary grasp at creating actually useful software.

It was lunch, certainly. Although incorrect, a vague…


Wow end of phase 1 already. Learning Ruby at Flatiron with my cohort, even with the pandemic’s unique sense of psychological time dilation, this first chapter has gone by so fast. So our final project is all about mastering the basics of designing, implementing and polishing a single application that can interface with an API. Now would you believe that in a span of about a week, I ended up creating three different attempts to satisfy minimum viable product requirements?

Take One: In charta mortuus est

I remember Friday, still a bit behind on labs. The notion was simple, I called it Y.A.R.N. for “Yet Another…


“In the beginning the Universe was created.
This has made a lot of people very angry and been widely regarded as a bad move.”

Douglas Adams, The Restaurant at the End of the Universe

Rare is a simple question resolvable with a simple answer. Truth, the small knowable portion of the Universe, is manifold. Like the complex genealogy of Veritas herself, truth is layers upon layers of internecine nested spheres of reality. Iterative notions cascading below and above the common human day to day experience. Legacies of discovery and causal chains of countless micro-decisions, building the real. If this prose is too purple or romantic, please accept my apologies but it will be a sincere and genuine stream of conscious — or at…
