Predictive market apps, also known as prediction market platforms, are apps or websites where people wager on what might happen in the future, and the prices show what everyone thinks will occur. Recently, a US soldier was arrested for allegedly earning $400,000 from insider information while betting using one of these apps. A few weeks ago, a group of customers took another app maker to court for not fulfilling their bet that Nicolas Maduro would lose his presidency. NPR reported this morning that 76% of the profits from predictive platforms come from just 1% of the customers, and many of those customers are bots. With predictive platforms being a hot topic, Alan N. Walter thought it was a good opportunity to explain what they are and how they are used.

Louis Perez will take us on a tour of the Best Summer Tech for 2026. Get ready for some cool products.

Last month Mark walked us through parts of his Club Membership Manager app an elegantly crafted HTML file that works on any operating system that supports a Chrome-based browser. CMM was created to give small clubs, associations, and community groups a simple, powerful, and inexpensive way to manage their membership rolls — without subscriptions, accounts, or cloud services. Everything you need lives in a single HTML file already on your computer. Your confidential club data stays on your desk, not on a corporate server. Once it’s complete, Mark is thinking of offering to sell it for a one-time fee of $24.95. As there is no limitation on the number of clubs you can run with it and it’s yours forever this is an excellent price. While CMM is in the final stages of development, Mark has started work on a new app.

Club Membership Revenue (CMR) is a self-contained, single-file web application designed to help you get a thorough understanding of the revenue generated from club or associatIon members. It seamlessly integrates with Club Membership Manager (CMM) to provide an in-depth analysis of your club’s finances. If you’re seeking a comprehensive understanding of your club’s revenue streams, CMR is your go-to solution. Unlike exportIng your club data for complex analysis in spreadsheets, CMR offers a visual representatIon of the data and the ability to generate on-screen and printed reports. Just like CMM, CMR was designed by Mark and created using AI to write the code of the app. Mark will walk us through how this app works.

Mark also used AI to help create two single page websites that promote CMM and CMR and will show you those as well.

Finally, Mark Astmann’s wife, Sherry, was curious about the nutritional content of different fruits and asked Alexa about each one, jotting down the answers. Mark thought this was a task for AI. He tried the same question with several AI tools, and these two stood out. ChatGPT whipped up a lovely infographic, and ClaudeAI created an interactive webpage showing all the information. Mark's daughter asked him to do the same for vegetable and and ClaudeAI created an interactive webpage showing all the information.

Letters to NJMUG

Date: 2/9/2022

To the New Jersey Macintosh Users Group,

I'm now a 51-year-old professional in New York City, but I grew up in New Jersey at a time when Apple was first rolling out the Macintosh. I now have two teenage sons myself, and after I was discussing what I did for extracurricular activities in high school, on a lark I looked up the New Jersey Macintosh Users Group, which I was involved in starting up. I was absolutely delighted to find the web page below referencing my participation, and I wanted to say thank you so much for memorializing the group's history. I'm glad it continues, and I'm writing to say how much I appreciate the costless but meaningful gesture of remembering the group's history. I'm only sorry I wasn't on a mailing list to be able to commemorate the 20th anniversary! Wishing best of luck, and another 35 years of success, to the New Jersey Macintosh Users Group!

Very truly yours,

Michael ("Mike") Waldorf
