Elementary Beta and BOINC

The other day I pulled down the 20170716 Beta 2 of Elementary OS 0.4. I tend to like the look of Elementary and if they ever get around the problems of 32-bit UEFI with a 64-bit CPU it will make a great choice for 2-in-1 computers. I loaded it on a 6-core AMD BOINC machine with 24-Gig of RAM, an SSD and an NVIDIA video card providing 384 CUDA core. Once it booted I noticed BOINC wasn’t finding a GPU. […]

Yes, I know many in the C++ world decry the use of a singleton class, but they, like […]

Raspberry Qt – Part 5

libqt5_stuff

I’m going to take you down the slow road. First we will get our application running on the Ubuntu development machine and test our cabling. Then we will go through the pain of getting Qt installed and configured on the Pi. I probably should have used a machine with a fresh Ubuntu install. This one was only a few months old, but I had already done quite a bit. QtCreator and a few pieces of Qt were already installed. At […]
