A little clever work and I was able to quickly set up a test machine with everything I needed on Ubuntu running in a Microsoft Azure VM.

Don't Develop GUI Tests, Teach Your App To Test Itself!

Mon, 16 Jun 2014 08:09:00 -0400

While developing native GTK- and Cocoa-based versions of the Plastic GUI, my team and I faced the challenge of developing a new test suite.

Test-Driven Design

Mon, 05 May 2014 10:00:00 -0400

Testing is valuable, but incrementally developing an optimal architecture as a side effect of testing is priceless.

Testing Behavior, Not Just Results

Thu, 19 Dec 2013 13:22:00 -0500

When you were a student, did you ever lose partial credit for an exam question that you answered correctly because you did so for the wrong reason? Or because you didn't show your work? Hold that thought.

New Year's Resolution: No More Bugs

Tue, 08 Jan 2013 23:39:00 -0500

Someone once told me that my job (and all my colleagues) should be eventually eliminated because they were an unnecessary expense. Instead, he said, it would be cheaper to never have any failures.

Debugging by Hypothesis

Thu, 13 Dec 2012 09:34:00 -0500

There's a technical term for people who claim that their programs don't compile because of a compiler failure rather than a bug in their own programs: arrogant.

Remote Mobile Debugging in Firefox 15

Firefox 15 has a cool new remote debugging feature for mobile developers.

Wall Street and the Mismanagement of Software

Wed, 08 Aug 2012 13:47:00 -0400

How Knight Capital becomes a knight errant when it came to software design and delivery.

techBASIC 2.0 Now Available

Tue, 24 Apr 2012 07:35:25 -0400

techBASIC is a really powerful platform for students and individuals interested in learning how to program using Post PC hardware.

Android on Android

Tue, 06 Mar 2012 15:10:06 -0500

The PC is the new mainframe, and the tablet is the new PC.

Keeping A Healthy Tech Diet

Coding in a Post-PC World, Part 4

Sat, 10 Dec 2011 07:44:31 -0500

I am a big fan of writing code from a tablet. Laptops can't beat the battery life a tablet provides, nor can laptops compete with tablets on size and weight comparisons.

Coding in a Post-PC World, Part 3

Sun, 04 Dec 2011 22:51:59 -0500

A year from now, my PC will be a relic from the past, like IBM Selectric Typewriters and CRT monitors

Android and iOS devices and the software I use to achieve my programming objectives.

Pretzel Logic

Sat, 12 Nov 2011 11:24:00 -0500

I want to show you what some very simple logic circuits in Verilog look like.

Coding in a Post-PC World, Part 1

Fri, 11 Nov 2011 06:25:37 -0500

The latest trend that has captured my attention is the impact of a Post-PC world on software development. I'm not talking about how we are using our PCs to run mobile device emulators and simulators to write software for those platforms. I'm talking about actually using those new hardware devices to write code.

Dark Corners and Social Forces

Wed, 09 Nov 2011 10:18:00 -0500

If you are thinking of solving a problem in an unusual way, you should have a reason for doing so. The more unusual the solution, the stronger the reason should be.

Electronic Legos

Fri, 04 Nov 2011 21:00:00 -0400

Each type of programmable logic device has its own peculiarities, and this week I want to look at what's available.

Bugs in Dark Corners

Wed, 26 Oct 2011 09:50:00 -0400

Today I would like to point out that programming in an unfamiliar style has another hazard: It is more likely to uncover the compiler bugs that often lurk in dark corners.
