Fedora 39 : testing Godot on Laptop and VirtualBox.

Today I watched a bit of the video series on the YouTube channel Fedora.
It's a whole team that maintains the Fedora packages and their development. I thought to check if I have the possibility to effectively use it in the development of software on Linux that has multiple functionalities. And because I currently work on Windows with Godot version 4.1.1 and C#, I took the first steps for installation and testing.
Let's install the Godot game engine tool on Fedora Distro Linux.
$ sudo su 
# dnf5 search godot
# dnf5 install godot.x86_64
# exit
Let's open and test with this command:
$ godot
The Godot interface comes with version 4.0.3 and is functional on my laptop with Fedora. Obviously, I have not tested all the implemented functionalities, but they seem to be good and ready to work.
On the other hand, testing on Virtualbox, it seems that it can't start the Godot interface.
It seems that Godot depends on OpenGL and needs some minimum requirements to work properly starting with OpenGL version 3.3.

Fedora 39 : How to start using cockpit tool in firefox.

Use lie any default installation like any Fedora Linux Distro package for cockpit tool with DNF or DNF5 tool.
$ sudo su
# dnf5 install cockpit
# systemctl enable --now cockpit.socket
# firewall-cmd --add-service=cockpit
# firewall-cmd --add-service=cockpit --permanent
# exit
The next step is to test if this runs well.
Get your ip address with netstat:
$ netstat nr
Because I used an virtual box for testing Fedora I get this ip 10.0.2.0
Use with firefox in the terminal:
$ firefox http://10.0.2.0:9090
The result will be the online cockpit tool.

News : An old change double equals is deprecated.

... although the change is old, for me it is new !
[root@fedora mythcat]# dnf install -y "kernel-devel-uname-r == $(uname -r)"

Using '==' operator in reldeps can result in an undefined behavior. It is deprecated and the support 
will be dropped in future versions. Use '=' operator instead.

Fedora 38 : Sway on VirtualBox.

Sway is a tiling Wayland compositor and a drop-in replacement for the i3 window manager for X11. It works with your existing i3 configuration and supports most of i3's features, plus a few extras.
You can find this desktop at this GitHub project.
The official webpage comes with a video tutorial on how to use it.
Installation is simple with these commands using the dnf tool:
# dnf group install sway-desktop-environment
# dnf install sway-config-fedora
It is possible to ask you for additional arguments for installation like this: --allowerasing or --skip-broken.
After installation, reboot and select sway from the desktop switcher
NOTE: The display for virtual video card from VirtualBox need to be set to Enable 3D Acceleration.
Let's see the result of this desktop environment ...

Fedora 38 : Openbox from GitHub.

I tried to use the OpenBox desktop environment in Fedora 38 and it seems to be incomplete, see also this thread.
I try to build the Openbox desktop from the source code, see the GitHub project.
$ git clone https://github.com/danakj/openbox.git
$ cd openbox
I need to install these: gettext-devel, glib2-devel, libtool, and pango-devel.X86_64 all devel libraries with dnf tool ...
Use the next commands, you will see some errors about some deprecated libraries and source code when you use the make command.
$ ./bootstrap
$ ./configure
$ make 
The go-to openbox folder to see the result:
$ cd openbox
$ ls -lFGC
The last step is to run the Openbox after you solve these:
Failed to open the display from the DISPLAY environment variable.
Openbox-Message: A window manager is already running on screen 0.
Because you are into environment area you need to close it.
After several attempts, I managed to pass these issues and ran the command:
$ ./xinit
This is the result is this:
I don't really have skills in this field of changes in Linux distributions and I wouldn't want to give wrong indications.

Fedora 38 : Deepin on VirtualBox.

Today, I tested the Deepin environment on Virtual Box where I installed Fedora 38.
I do not recommend using this desktop environment on Virtual Box because it requires graphics resources.
Installation is simple as with any desktop environment installation, see this official webpage.
Here is the final result:

Fedora 39 : FASM tool in Fedora.

I searched the internet about the FASM tool and found references that it would be included in the Ubuntu distribution.
If you want to use FASM with the related language in the Fedora Linux distribution, then find the commands in the image below:

Fedora 39 : Test with eDEX-UI.

eDEX-UI is a fullscreen, cross-platform terminal emulator and system monitor that looks and feels like a sci-fi computer interface.
This can be found on this GitHub project.
This is version for 64-bit Machines, you can download it with:
$ wget -c https://github.com/GitSquared/edex-ui/releases/download/v2.2.8/eDEX-UI-Linux-x86_64.AppImage
Change the file to be executable:
$ chmod +x eDEX-UI-Linux-x86_64.AppImage
Use this command:
$ ./eDEX-UI-Linux-x86_64.AppImage --appimage-extract
Go to this folder:
$ cd squashfs-root
Run the application:
$ ./AppRun
This is the result of running the application:

Fedora 39 : Resize the vdi file for VirtualBox.

NOTE : This will not change the size of the Linux partition. I tried to change the size in fedora linux with specific commands, but I didn't succeed. The distribution I tried was a server without a graphical environment so I could also try gparted software.
It is good to use the Fedora Linux distribution for tests and feedback to the Fedora team on a hardware system, such as an old laptop.
For quick tests and to save time, you can also install a version on VirtualBox, and sometimes you may not have enough space on the virtual disk.
You can try a tool called VBoxManage with this command to your named vdi file:
VBoxManage modifyhd "C:\Fedora\Fedora.vdi" --resize 81920
You may receive this error:
0%...VBOX_E_NOT_SUPPORTED
VBoxManage.exe: error: Failed to resize medium
VBoxManage.exe: error: Resizing to new size 190756945920 is not yet supported for medium 'C:\Fedora\Fedora.vdi'
VBoxManage.exe: error: Details: code VBOX_E_NOT_SUPPORTED (0x80bb0009), component MediumWrap, interface IMedium
VBoxManage.exe: error: Context: "enum RTEXITCODE __cdecl handleModifyMedium(struct HandlerArg *)" at line 937 of
file VBoxManageDisk.cpp
You can check information about the vdi file on which the Fedora distribution is installed with this command:
VBoxManage showhdinfo "C:\Fedora\Fedora.vdi"
Make a clone of the vdi file.
VBoxManage clonehd "C:\Fedora\Fedora.vdi" "C:\Fedora\Fedoracloned.vdi"
...

Resize this cloned virtual disk with this command:
VBoxManage modifyhd "C:\Users\catafest\VirtualBox VMs\Fedora\Fedoracloned.vdi" --resize 30000

Fedora 39 : DNF, DNF-3 and DNF5

Before installing DNF5 you should know that your installations with this tool in the fedora distribution may not work correctly
After implementation of dnf5 module install dnf and dnf5 cannot share the same location for storing state of modules, because dnf5 will store additional information about installed profiles (braking change). Modules enabled by DNF5 (dnf5 module enable <module>) will be not seen as enabled in DNF. Module profile installed by DNF5 will be not sees as installed in DNF. DNF will only see installed RPMs.
More details on this official webpage.
You can fix it with the dnf-3 tool if you accidentally modified or deleted the dnf tool.
A simple example is installing Deepin Desktop, which I could only install with DNF-3:
# dnf-3 install @deepin-desktop
The other dnf and dnf5 tools didn't work, I didn't wait to check if it's because of the repos. but it did not bring me the packets from the web and shows me transactions of 0 B.
