Daring to Defy Software Extinction: A Limited History of Development Tools

Published June 21, 2017 by Geoff Perlman

In 1998 Steve Jobs was the interim CEO of Apple and trying to keep his unprofitable company from sinking into bankruptcy. Just the previous year, when asked what he would do if he were in charge of Apple, Dell CEO Michael Dell said, “I’d shut it down and give the money back to the shareholders.”

The Mac had single digit marketshare. Creating a development tool, independently of Apple or any company that makes a platform such a tool would support, was considered a fool’s errand. There were plenty of tools available from large companies. Apple made MPW (the Macintosh Programmer’s Workshop). Symantec created THINK C. Metrowerks developed CodeWarrior.  IBM’s VisualAge. Macromedia Flash. If you needed to create a cross-platform desktop app, you’d be told to look no further than SUN Microsystems Java: THE cross-platform language. We were all promised that Java was going to run on everything from our computers to our cars to our can openers. Java was the safe and popular choice. Developers made up only about 5% of computer users anyway. Honestly, who would be crazy enough to launch a new development tool in a  market crowded by giants?

We were.

Easily Sorting Arrays of Classes

Published March 9, 2016 by Paul Lefebvre

Sometimes you’re going to need a data structure that is an array of classes and you’re going to want to sort them. The standard array Sort method can only sort simple types (Text, Integer, etc), so what do you do?

The traditional technique has been to use SortWith. You create a separate array of a simple type, populate it and then sort the temporary array using SortWith to sort the class array.

But there is an even slicker way to sort that was added in 2015 Release 3. You can now create your own custom comparison method and use that to sort the class. This custom method returns 0 if the values to compare are equal, a positive if the first value is greater than the second, and a negative value if the first value is less than the second.

The New Xojo Framework: Ch-ch-ch-ch-changes

Published April 14, 2015 by Geoff Perlman

In the ideal world when you do something, you do it right the first time. In the real world, we learn more each day and what seemed right yesterday, a month ago or a few years ago, may no longer be right today. Xojo has been around for a long time now and in all that time we have learned a thing or two. One of the things we have learned is how to deal with errors.
