In reviewing the while loop in Java I am baffled how most every example, no wait, that's wrong, how every example, that's better, even the AI generated ones, could be handled in a for loop.

I looked up my name at www.theatlantic.com/technology/a... and low and behold my book was on the list. Should I be flattered or should I ask my publisher to sue the pants off of Zuckerberg?

1/3 To my Windows using friends, I just discovered a technique that has eluded me up until now. When you use a single or double quotation mark in Word it is a curly mark and if you use a second mark it will curl in the other direction to indicate these two symbols have enclosed other characters.

I found these a few years ago. When I was 16, 55 years ago, I was on a television show called Reach for the Top. Two high schools teams of four competed in answering questions. Rather than have a local competition to see who would make the school team we were just interviewed by a teacher.

All that is left to do is sign the contract and then work begins on my second book. I was surprised when I was first asked to write a book and now I am writing another one. Keeping my ego in check will be difficult 🤓

Have you ever looked for info about the Java language only to find mostly YouTube videos. They frequently go on and on before and after they provide the info you want. In one video the presenter left to answer a phone call, left the camera on, and uploaded the video without editing out his call. 1/3

I’m vain. Today I went to the Cote St Luc Public Library to have a photo taken of me with a copy of my book that I donated to the library. I’m sitting in front of the section where it will be shelved.

A few years ago I came across Duet Display, a program that runs in iOS and Windows. It allows you to use your iPad as a second display. When I don’t feel like working in my office I can work in our dinining room and have the larger viewing surface of two screens. Highly recommended.

Microsoft kindly gave me, and probably anyone else with an AI co-processor, a preview app called Recall. It appears to make a copy of your display and then reads the display. You can then ask it questions like "When did I write about classless Java".

What The Fuck. From a CNN about GOP ‘hardliners’ blocking a budget bill as it did not make cuts to Medicaid & “Another one of the holdouts, Clyde, had another issue with the bill — its failure to remove gun suppressors, also known as silencers, from regulation under the National Firearms Act.”.

Had a great supper last night with fellow speakers and jPrime organizers. Even managed a little over 6 hours of sleep despite the 7 hour time difference from Montreal.

I learned that to get a random number from 1 to 10 I:
Random r = new Random();
var secretNumber1 = r.nextInt(10) + 1;
Today's emphasis on security there are now algorithms to choose from such as:
RandomGenerator g = RandomGenerator.of("L64X128MixRandom");
var secretNumber2 = g.nextInt(10) + 1;
Random r = new Random();
var secretNumber1 = r.nextInt(10) + 1;

I donated a copy of my book to my city’s, Cote St Luc, library. Went to their web site to see if it has been cataloged and discovered that someone has checked it out.
