Xojo Programming Language: 6 Fascinating Facts

Published April 18, 2016 by Paul Lefebvre

Xojo is similar to VB, Java and C#

The Xojo programming language is fully object-oriented and uses an object model that is quite similar to VB, Java and C#. If you are used those languages at all, you’ll be right at home with Xojo.

Available since 1998, Xojo was one of the first languages to use Automatic Reference Counting (ARC), something that other languages such as Swift and Objective-C now use. Xojo is type-safe and fully object-oriented making it easy to learn and use, but it also has advanced features such as namespaces, extension methods, exception handling, introspection, delegates and more.

Easy as Pi: GPIO updates

Published April 13, 2016 by Paul Lefebvre

We are always keen to see apps and projects that Xojo developers have made for their Raspberry Pi 2 and Raspberry Pi 3 single-board computers. Especially since Xojo 2019r1 when building for Pi Desktop and Console is free with Xojo Pi!

I am pleased to announce some updates to our GPIO project to make it even easier to use more types of hardware in your Raspberry Pi projects.

Headless Pi: Using Xojo and Raspberry Pi Without a Display

Published March 30, 2016 by Paul Lefebvre

You don’t need to hook up your Pi to a physical display, keyboard and mouse. You can set up VNC on the Pi so you can remotely connect to it.

My Raspberry Pi 2 sits on my desk next to one of my speakers. It’s not hooked up to any display. I use a combination of SSH, SFTP and VNC when I need to work with it.

Raspberry Pi 3 Announced!

Published March 8, 2016 by Paul Lefebvre

On Monday February 29th, the Raspberry Pi Foundation announced the new Raspberry Pi 3. This updated Pi has some significant improvements over the Pi 2, including:

  • A 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU (~10x the performance of Raspberry Pi 1)
  • Integrated 802.11n wireless LAN and Bluetooth 4.1
  • Complete compatibility with Raspberry Pi 1 and 2

That last bullet point is notable because it means that Xojo is also fully compatible with the new Raspberry Pi 3!

The Citizen Developer

The Citizen Developer

Published November 19, 2015 by Paul Lefebvre

I’m seeing more and more headlines about how citizen developers are helping create the apps that business need.

In particular, a recent article at ZDNet, “The advent of the citizen developer” talks about how non-programmers can help create the apps needed by an enterprise company:

So the business-side has long had to place their fate in the hands of those with the requisite skills but often with little sympathy for or first-hand knowledge of the business itself. Or they just ended-up acquiring pre-existing software that was a close enough fit, and then had it configured to their needs. Neither path has typically produced tech solutions that fit business needs very well, and ‘good enough’ has usually been the mantra of the day.

These articles explain how “citizen developers”, sometimes referred to as a business analysts (or maybe even power-users), are using rapid application development tools to create apps that helps the business solve a problem more quickly than going through a more formal and lengthy IT process.

Build All The Things

Published November 11, 2015 by Paul Lefebvre

As you may have heard, Xojo 2015 Release 3 added the long-awaited ability to create 64-bit apps. And it also added the ability to create Raspberry Pi 2 apps (Linux ARM). This now means there are lots more apps that can get built.
