Tech Tidbits & More

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.

• Ridiculous Delivery Status Notification

  I received the most ridiculous email today, an idiot demanding $1,490 to keep them from releasing who knows what about my internet usage. Yeah, whatever. The fact that they're still sending emails out like this means that some people actually fall for this ridiculousness; I'm sharing so you'll know its just a scam.

  I received what I knew to be a scam message yesterday, but I couldn't tell what the scam was. When I opened the email on my Android phone, all I saw was the following a subject line of Confirmation Needed for SLTT71EDUPHA and a message body of:

• Update Amazon Payment Information Scam

  Sunday, April 19, 2026 at 03:19 PM | Categories: Phishing

  AI Generated   I got a phishing email that looked very convincing on my phone, but once I read it closely I saw it was fake. The subject claimed I needed to update my Amazon payment information, while the body said my account was locked for unusual sign-in activity and then oddly told me I could ignore the email. I also noticed the reply-to address was clearly not Amazon, and the fake copyright notice at the bottom was another giveaway. The main takeaway is to be cautious and never click links in suspicious emails.

• Really Stupid Phishing Attempt

  Tuesday, April 7, 2026 at 04:56 PM | Categories: Phishing

  AI Generated   I got a clearly phishing email pretending to be a password reset notice for my domain. It was easy to spot because it used my domain in a way that didn’t match how my hosting actually works, had no branding or personal greeting, and the links pointed to a completely unrelated URL.

• The Fumbly Workshop

  AI Generated   I’ve been spending more time on woodworking than tech lately, so I launched a separate site for those posts called **The Fumbly Workshop**.

• Inappropriate GitHub Solicitation

  Saturday, April 4, 2026 at 09:24 AM | Categories: Miscellaneous, Phishing

  AI Generated   I got a suspicious email from someone named James Ferry proposing a “partnership” where I’d use my profile to land US jobs while he did the work and we’d split the money. At first it just seemed shady and unprofessional, but then I noticed red flags.
