Would anyone know of any good 6-12 month tech schools in the US that offer job placement? Looking to specialize in Full-Stack JavaScript. — Keith D Commiskey https://keithdc.com

[2018-01-07 / 08 – Sun / Mon] Setting up a new VirtualBox VM with Ubuntu 16.04.3 (guest) on a Windows 10 MSI laptop (host/parent). I was recently reintroduced with Foundation 6, and I decided it would be a good opportunity for a little redesign of my portfolio. This guide became a byproduct of my setup…

Figured I’d take a break from my daily JavaScript adventures (w/ Codewars) and learn a little Node with Express and MongoDB. Although it says 30 minutes, after downloading, creating an account, and installing Postman, learning what it is and how it works, then doing all the same with mLab (MongoDB), then figuring out why MongoDB…

From time to time we need to make little tweaks to our career paths. Although learning React Native was next on my path, I’ve decided that learning another framework, even though it’s close to React, would continue taking me laterally; whereas at this point, I now need a much stronger foundation for my current skill-sets.…

Coming up on my 1-year of being ‘between jobs’ (reasons explained within), figured I’d pay a tribute to all my developmental years up to now. Beyond the technologies I’ve semi-mastered along the way, and the projects I’ve completed, I’ve always enjoyed learning and, quite simply, being productive. I started programming with Atari Basic. I used…

My first React app is now live. It’s called “Track Your Cash” and is a simplified checkbook register. The project uses React, React Router 4, and Redux, and runs on a Digital Ocean Ubuntu-based NGINX server. “Track Your Cash” Demo: https://kdcinfo.com/app/register/(this will redirect to Digital Ocean’s IP address) View the code on GitHub: https://github.com/KDCinfo/track-your-cash This…

I put the code for my ‘Guess Right’ game on GitHub. It includes the Vue files, Vuex state files, Laravel routes, model, controller, and migration files. It also provides a link to a flowchart diagram and a couple mockups I did for the game. — Keith D Commiskey https://keithdc.com

I’m proud to announce I’ve fallen in love with my first framework; Vue. Well, second actually, with Laravel being my first. Both of these have helped to bring me into the world of… now? Both have allowed me to create a mini-site showcasing Laravel, with Keep Track and Pick-a-Meal, and now Vue, with Guess Right.…

The learning is endless, but exciting. The following 5-lesson series is an awesome primer on Vuex (Vue state management). — Keith D Commiskey https://keithdc.com

The link and code provided below is extracted from code I wrote for a Controller class used on my Laravel site, Keep Track. IIRC my biggest achievement while creating Keep Track was on the item listing page. Sorting (and one level of sub-sorting) on separate/related tables, for me, was tricky. But I was able to…

Pick-a-Meal is an online “Random Food Type and Restaurant Selector”. You choose multiple Food Types or Restaurants from a list that you create, and it will randomly pick one for you. https://kdcinfo.com/pickameal/ I (re)built Pick-a-Meal to continue learning more about Laravel. My older, downloadable, version was done in very old school PHP(4). The new online…

Keep Track! … an online inventory manager for keeping track of all types of ‘stuff’… “Your Stuff!” http://keeptrack.site I built Keep Track as a way of learning Laravel, MVC, and Bootstrap. I created the entire project from scratch; migrations, models, controllers, views, AJAX, and more. I worked on this project (whilst learning Laravel) on and…

Just activated my website’s redesign. Long time coming. Last redesign was 2002. Disclaimer: I’m not a designer! Site: https://kdcinfo.com Please feel free to let me know if you experience any issues. Although I began Dec 2014, this was an on-and-off project. If I had worked on it as a regular day job, it likely would have…

The Award Not an official award, but wanted to give kudos and special mention to RBGameHunter on eBay for all of his help in getting me up and running. The Situation Ten months after my last move, I decided it was time to pull out my Atari 800 and get her up and running again…
