Gambas with Class

The simple principle of "code re-use" is an easy way of reducing project development time and improving the quality of your software.

It is clear that using existing code snippets will save you time by avoiding the task of "re-inventing the wheel".

And if you also keep a personal store of code that you have previously designed and tested, this should help improve the quality of your software projects.

RaspberryPi, Device Tree & why my DS18B20 app is broken

One of the problems with writing about Linux, the Raspberry Pi and technology in general is that posts can quickly become out of date.

I know I won't remember the details the next time I have this problem, so I need to write it down.

So will the BlockChain change our lives, or is it a techno dead-end?

You would have to be crazy to write your own XML editor when there are so many available, right?

Well, when opening the XML file from my Garmin eTrex in a variety of editors, my low power Linux laptop grinds to a halt.

As I only need to extract individual Tracks from the eTrex file, I decided to write my own program.
