The Internet has no shortage of “how to cross compile Qt for Pi Web pages.” Most of them kind of were “right enough” at one point in time for a subset of people. Most of them don’t bother to tell you what the host system is. I suspect many of them used a 32-bit host system which masked most of the problems with their instructions. The instructions found here definitely fall into this category. How … How Far We’ve Come – Pt. 18Read more

As I pointed out many times in my Qt and databases book, most of the database examples you find online and even in official Qt documentation are shit. This is not my ego talking.

If this were one of my geek books, we would spend an inordinate amount of time with me dissecting code in order to teach you something.

We need a third app. While I thought it would be nice to use the other two by themselves, I got looking into the soon to be extinct Android platform and, we need something simpler to verify cross compilation works before jumping into either of those. Why? PostgreSQL only runs under this command line utility, going to jump through hoops trying to access it from a GUI app. The 2-in-1 doesn’t provide a serial port … How Far We’ve Come – Pt. 12Read more

This post is a bit of housekeeping. Since I started this series my development machines have all moved to KDE Neon so I started reading forward from the original post and when I got to this post I realized we didn’t have a pre-installed method of restoring a Raspbian image. Yes, there are lots of posts giving you the dd command for restore after you run a bunch of other commands to identify the SD … How Far We’ve Come – Pt 11Read more
