How do you compute a massive number raised to the power of another huge number, modulo something else? Use Xojo to solve
I am so excited to be planning the Xojo Developer Retreat coming up in Nashville in September. We decided to call it a retreat to signify that we are emphasizing the part that attendees over the years has told us was the best and most beneficial part of XDC, the time spent with other users – networking, troubleshooting and building relationships. If you want to meet the Xojo Team and community members, attend some great sessions, network, collaborate, have fun and enjoy Nashville, please join us at the Xojo Developer Retreat.
The Game of Life, also known simply as Life, is a cellular automaton devised by the British mathematician John Horton Conway in 1970. You’ve probably seen this around in some form or another, but I ran across it again recently and thought it would be fun to implement in Xojo.
With just a few lines of code, you can create a Xojo app for iOS and Android that shows a new cat picture each time you launch it. I call this app “CatsUp!”. It’s a play on ketchup/catsup, get it?
If 2020 was a year of change for Xojo, 2021 was the year many of the pieces fell into place. From API 2.0, an Android pre-release, Apple Silicon native IDE, building and remote debugging 64-bit macOS apps from Windows and Linux and dark mode on Windows, 2021 saw a lot of hard work behind the scenes come to fruition for Xojo.
This is a very exciting week at Xojo! Not only is Xojo 2021 Release 3 here, but we are thrilled to announce that the new Xojo Android platform is now is pre-release testing! In celebration of these two milestones, Xojo’s Black Friday sale starts now and ends November 29th at 11:59PM CT. There’s never been a better time to get Xojo!
Yuck! It happens to everyone, from beginners to experienced developers: sometimes you’ll get stuck. Perhaps the code you’re working on just won’t do what you want or maybe you’re having trouble understanding code plucked from the internet. Talk to the duck. The rubber duck, that is. The term “rubber ducking” or “rubber duck debugging” is a software development technique where you explain the problem you are having to a rubber duck (or appropriate substitute). Often the act of explaining the problem to someone else, even if that someone is not real, can help you figure it out. It might be like inspiration struck.
I recently watched this video from Computerphile on YouTube (one of my favorite channels). It demonstrates a simple bit-shift operation can generate amazing random strings of numbers. I thought I’d quickly convert it to Xojo.
On this day 25 years ago I wandered into the local Chase Bank here in Austin, Texas to open a checking account for my latest venture. At that time I was planning to write custom software applications for various businesses that were interested in hiring me to do so. Not long after that, one of the developers who worked for one of my customers asked if I’d be interested in hiring him. Jason and I still work together to this day. What you now know as Xojo came along about 18 months later. As we prepared v1.0 to ship, we wound down the custom software development part of the business. We’ve been a development tools company ever since.
Here’s a fun little project you can try to get a feel for some simple animation in your iOS and future Android apps.
