Welcome to the Internet Home of John M. Wargo; I created this site back in 2009 so I could post articles about things that interested me. Herein you’ll find articles on a lot of different topic areas: Mobile development, Web development, Internet of Things (IoT), and a lot more. Every time I learn some new technology or complete some cool or interesting development or IoT project I publish an article here.
You’ll also find information about my books, source code projects on GitHub, and articles published in or on other sites or magazines, even videos of my many conference presentations or project demonstrations. I’m also especially fond of the series of Stupid Developer Tricks posts.
You can view all articles in reverse chronological order, or you can find articles by category. Of course, if you can’t find what you need in those views, use Search to find anything anywhere on the site.

As you probably know from this site, I'm a geek and a software developer. I'm also a woodworker and it feels like I'm going to pull in more woodworker stories this year - mostly because I've been doing more woodworking than coding lately.
Over the US 4th of July holiday, we were hanging around with family when my sister in law mentioned that she wanted to get an Owl House for her back yard in order to attract an owl to live in her yard. I'd never made an Owl House before, so I quickly volunteered to make one for her.
Describes a node.js based CLI I created to make it easier to deploy multiple Google Cloud Functions with a single terminal command.
I received another supposed Chase Bank Phishing email the other day and thought I'd spend some time analyzing it.
I often get LinkedIn connection requests where I just don't understand the potential connection value.
AI Generated I recently published a post about 3D printing but forgot to set a description. Luckily, I used the Describer GenAI extension for Visual Studio Code to quickly generate a description for me. It only took a few clicks and seconds to add a nice description to the post before publishing it.
AI Generated I bought a 3D printer during the pandemic but struggled with it, so I upgraded to a P1S printer from Bambu Lab. The new printer is enclosed, self-leveling, and fast, making it easier to use. My daughter loves using it for cosplay projects. I also bought a lot of filament and have been impressed by the quality of free models available online. I recently used the printer to create a wooden enclosure for a T5 e-Paper display unit, but had to find a 3D printer plan for a better fit due to the unit's design. The prints turned out amazing, and I'm excited to see the final result.
I received a phishing attempt the other day and thought I'd poke some holes in it.
A while back, while anticipating a particular event (my retirement), I decided to create an app that allowed me track the number of days until the event. One thing led to another and I decided to create a more generic version of the app so I could write about it here.
In my previous post, I mentioned that I like building electronic projects I find online. Historically, I purchased a lot of project components from online vendors like Adafruit and Sparkfun. Both offer their own proprietary boards as well as some standard electronics components you can use for your projects (such as battery connectors, cables, breakout boards, other connectors).
