 (So, this could be a very good week or very bad. My old desktop started to behave very annoyingly, freezing every ten minutes is not the ideal scenario. Happily, I had a spare CPU I was using for Windows applications only, so I decided to take it. Because I have some spare AMD Radeon R9 290 GPUs, I decide to install one of them.

Again, I have been getting into photography so again, processing RAW files with the CPU is not a good idea. Not even if your desktop has twelve cores. So I had had to figure out a way to make it work.

As I had described in the article where I made my discrete NVIDIA work with Darktable, this software needs the IMAGE support. So, the situation is the following:

  • only the proprietary AMDGPU PRO module offers IMAGE support, so no Radeon module.
  • the AMDGPU PRO requires X.Org 1.1xx, Mageia 7 comes with X.Org 1.20.x

Here it is what I did to make it work.

As I have written before, after more than five years it was time to retire from hard work my trust old laptop. I decided to get an HP Omen. I must say the hardware is quite amazing and to get the best of it I installed Mageia 7 (current version when writing the articles).

Recently I have been getting into photography (I will write about that later) and of course, getting the software to develop RAW files is a must. I think Darktable is the best for it; however, this kind of software is really heavy, even this super powerful laptop with 12 cores at 3+ GHz got dizzy. Fortunately for us, Darktable supports GPU processing which offloads the CPU and displays the images almost right away.

Configuration to make this possible is kind of tricky. I will put here my notes hoping it will help other fellows Linux photographers. My notes are on Mageia but I am confident that anyone could apply them to their own Linux distribution.

It took me weeks to figure it out.

A Class 4 PBX? What it is? In short, a class 4 PBX is the one that interconnects different PBX. It is very common that this class of PBX doesn't have contact with end-users. The perfect example of class 4 PBX is the carrier that sells IP telephony companies the DID's (origination) and outgoing gateways (termination). There are more differences between a 5 class and a 4 class PBX, my article about that covers it.

For the sake of this article, let's pretend everybody knows what is a class 4 and a class 5 PBX. Let's discuss FusionPBX. FusionPBX, out of the box brings let's say, 90% of all the needs a class-5 PBX needs: voicemail, IVR menus, time conditions, queues, and a lot of more features that are useless if all you want is a class 4 PBX.
