Fedora 39 : About Penpot online tool.

Designers and developers can finally work in unison to build beautifully designed software experiences that truly scale up.

Penpot is the Open-Source Design & Prototyping Tool for Product Teams.

If you have worked with Adobe XD or similar software, then it performs the same functions.

I haven't tested it very thoroughly, but I can tell you that it works very well and is open-source and free.

I haven't seen anything about Bootstrap in the library of bookstores and templates, but there are quite a few in other areas with a pretty good design.

You can test it on the official webpage.

See these videos from the official youtube channel:

News : Fedora 39 i18n test week starting 5th September.

We will be having the Fedora 39 i18n test week starting 5th September.

Check details about this test week event at https://fedoraproject.org/wiki/Test_Day:2023-09-05_I18N_Test_Day wiki page. You can submit your results on page https://testdays.fedoraproject.org/events/161

Fedora 39 : Issues in Fedora with PyGobject and sway-tests.

Today I wanted to test this repo named sway-tests.

I followed the steps there and received an error from gi.repository.

This error is related to another issue related to PyGobject.

In Fedora Linux distro, installing PyGobject is done with pip like this:

$ pip install PyGobject

In order to have no errors, the dnf or dnf5 tool should be used like this ...

I tested the functionality of this installation with a simple example:

import gi

gi.require_version("Gtk", "3.0")
from gi.repository import Gtk

win = Gtk.Window()
win.connect("destroy", Gtk.main_quit)
win.show_all()
Gtk.main()

It worked very well.

After solving this issue, I returned to the initial one and tested the sway-tests.

$ whereis sway
$ env/bin/pytest --sway=/usr/bin/sway
$ sudo env/bin/pytest --sway=/usr/bin/sway

I used the command both with and without sudo.

Both generated the same errors.

For the following command I had to install ... xorg-x11-server-Xephyr:

Xephyr is an X server which has been implemented as an ordinary X application. It runs in a window just like other X applications, but it is an X server ...

... the fixed centered black window specific to the xorg runtime appeared and somewhere on the side the terminal showed me a bunch of errors.

... obviously, I don't know how well sway-tests is implemented, now it's an archived repo, but I solved the use of PyGobject in python on the Fedora linux distribution.

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.
