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.

I received an interesting email today that seemed to be from American Express indicating that someone (most likely a hacker) updated the phone number associated with my account. The email subject said: "Request To Update Your Contact Details Was Successful." and I almost panicked and clicked the link before I gave this careful thought.
Google recently started asking for ID verification for Play Store developers. The time came for me to submit mine and I dutifully submitted both a scan of my passport as well as a scan of my driver's license (both sides). Google, of course, repeatedly failed the verification process without telling me anything about what was wrong with my submission.
In Postal Scam Urtye dot com, I pointed out a lot of different ways you can easily tell when a text message you receive is crap. I received a lot more of those types of text messages lately and it's fun to watch them evolve.
A few weeks before the 2024 election, I suspended my campaign for president. I didn't want to keep votes from the candidate I wanted to win. I'm getting ready to delete the web site for my campaign but I thought I'd share with you links to the campaign store in case you want to pick up any Wargo 2024 branded items as a form of protest against our political system.
After publishing my link checker utility, I realized I wanted the ability to write the utility's settings in a project folder so I could quickly scan links for that project.
When I migrated this site from Joomla! to Eleventy, one of the things I didn't spend much time on was validating the links in the site (both internal and external links). I recently decided to spend some time to check all of the links in the site and ended up spending time building a utility that automated the process for me.
Describes a node.js-based utility I created and published to validate web links in a web site or page.
Over the years, I published a variety of Node.js modules and CLIs; the CLIs because I wanted to automate some operation I needed to make easily repeatable. For my CLIs, I started building them using command-line arguments, but I quickly forgot the arguments and order. Next I used configuration files, but then that tied me into a specific file or set of files for different operations. Eventually I started using an npm module called prompts that allows me to prompt for all of the configuration options either as the only input into the program or for writing the settings to a default configuration file. Yesterday I spent some time figuring out how to do conditional prompts, so that's the topic of this post.
Imagine my surprise when I received an email from Amazon letting me know that an album I purchased a while ago, (Opeth's Last Will and Testament), wouldn't be delivered until 2036.
I decided recently that one of the things missing from this site was the ability to have call-outs in the content. My buddy Scott Good was here this weekend working on something in my workshop, so, while we waited for some glue to dry, I asked him to add some call-out CSS to the site. After he left, I added some code to the site to make it all work.
