I know, complicated isn’t it.

I was having problems with tracker miner beavering away for 1/4 of an hour every time I booted up. Had a look at the journalctl output etc and noticed errors around the database.

So I Duck Duck Go-ed some stuff and eventually found:

tracker reset --hard

Once I ran that and rebooted, it ran again for a bit then settled down again. Problem solved.

Run selected code:

search for Execute Selection in Python Console, to find and/or change your keyboard combination.

You need gdb 7.0.0 or higher.
You are using: GNU gdb (GDB) Fedora 10.1-2.fc33

I was using Kdevelop under Gnome on Fedora 33 and wanted to debug a program. Unfortunately the above error pops up telling me it won’t work I need GDB version > 7 but all I have is GDB version 10, and any fool knows 10 < 7 so what’s a guy to do?

So I thought I’d try LLDB instead (Run -> Launch Configurations -> Debug) but that gave an error of can’t find lldb-mi. So more ducking (DDG) later I found a bug report from Arch (if only I was linux enough for Arch) that stated that LLDB-mi no longer comes with LLDB install and you had to build it from source.

So I:

sudo dnf install lldb-devel llvm-devel 

then downloaded the repo from https://github.com/lldb-tools/lldb-mi

cd Projects/github/
git clone https://github.com/lldb-tools/lldb-mi
cd lldb-mi
cmake .
make
sudo make install

…and LLDB debugging in Kdevelop works fine now.

Not sure what’s up with GDB but I’m sure it’ll be sorted at a later date. It was after an update that it started falling over.

Download the source code from https://supercollider.github.io/

Install some requirements:

sudo dnf install avahi-devel emacs emacs-devel libXt-devel libudev-devel libsndfile-devel jack-audio-connection-kit-devel qt5-qtwebengine-devel

I was getting errors like

CMake Error at /usr/lib64/cmake/Qt5/Qt5Config.cmake:28 (find_package):
Could not find a package configuration file provided by "Qt5Svg" with any
of the following names:

Qt5SvgConfig.cmake
qt5svg-config.cmake

sudo dnf install qt5-qtsvg-devel qt5-qtwebsockets-devel

…everything worked OK:

cmake .
make
sudo make install

and run

Just bought a VHF radio with GPS logging (see title). I had assumed that when you connected a computer to it as a USB device it would be just like a thumb drive. Unfortunately that wasn’t the case.
You can download some special software for PC download (sic) but that doesn’t include Mac or the mighty Linux. So some DDGing later brought me to https://github.com/cr/hx870 which uses python to access it.
It was easy to set up a virtual environment for python 3.6 and use pip to install from the github repo.
You can make sure it is connected to USB, using… lsusb it should show an entry for a device called Yaesu Musen HX890

Then:

Then use:
hxtool gpslog -g yourfilenamehere.gpx or (-j for geojson format)
…to transfer you GPS log from the device to your PC.

Once you have the file safely on your hard drive you can open it using something like QGIS with the GPS tools installed (GQIS -> Plugins -> Manage and install plugins -> (search for GPS) -> GPS Tools (tick it)
Then Vector -> GPS Tools -> [Load GPX File]

By the way to access the setup menu (just in case you haven’t read the manual) hold down the menu/set button for a second or two instead of just tapping it. You clear the log by using the GPS settings menu.

Having given up on people telling me what I don’t want (GNOME). KDE is now the GUI of choice.
An install of fedora KDE spin and here are my initial installs:

dnf install fedora-workstation-repositories
dnf config-manager --set-enabled rpmfusion-nonfree-nvidia-driver
dnf install akmod-nvidia

dnf install https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
dnf install vlc

Don’t forget you’ll also want to install RStudio,etc. and make the adjustments to your .bashrc file for the powerline to work.
…and you know what did it for me? Desktop backgrounds.

And the downside is that I’ll now spend about 2 hours adjusting settings to get my look absolutely right 🙂

Not running stuff on Fedora 31 unless you run:
 systemctl --user restart xdg-document-portal

…before hand. Something to do with flatpak apparently.
