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.

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.

Raspberry Pi GPIO Module On GitHub

Published November 10, 2015 by Paul Lefebvre

In order to interface with the Raspberry Pi, you often want to use the General Purpose Input/Output (GPIO) port. It is easy enough to connect a broadboard to the port, but how do you write Xojo code that can talk to the port?

Guest Post: Part 1, Transparent Label Tip for Windows

Published November 6, 2015 by Xojo

Wayne Golding has been a Xojo developer since 2005. He operates an IT Company Axis Direct Ltd www.axisdirect.nz which primarily develops applications using Xojo that integrate with Xero www.xero.com. Wayneâs hobby is robotics where he uses Xojo to build applications for his Pi2 often implementing IoT for remote control.

When developing for Windows, it’s not immediately clear how to set up a transparent label. If you change the background colour of your Window, you could end up with that ugly gray label. And of course I always forgot to set the transparency until after the debug run. But I’ve found a simple solution.

How I learned to stop worrying and love the debugger

Published September 8, 2015 by Xojo

Since we are all good programmers we never make mistakes, right ? 🙂

But for those times when you write some code and you just can’t figure out why its not behaving, there is always the Debugger!

The best part is the Debugger is very easy to use and it can help you sort out a lot of common issues. Its covered in the Xojo User’s Guide, specifically see the Using the Debugger section.

Take A Core Dump: What to do when your app crashes on Linux

Published August 17, 2015 by William Yu

With many things in life, more choices means more freedom of expression. We can pick and choose what we like personally as a way to express ourselves. Such is the world on Linux. The myriad of different Linux distros along with all the different Desktop managers and Window managers available are daunting. While more choices is nice (in general anyway), it can also cause more confusion. As a cross-platform developer, you’re probably aware that every operating system has their own way of dealing with crashes and crash reports. On Linux this is no different, but it is more confusing because not every Linux distro plays by the same configuration. This blog will answer some fundamental questions you may have about what happens when your application crashes on Linux.
