News : Flutter on Fedora 40.

Flutter transforms the development process. Build, test, and deploy beautiful mobile, web, desktop, and embedded experiences from a single codebase.
Read more on the official webpage.
Theoretically, Flutter can be used much easier in the Fedora 40 Linux distribution than in a Windows operating system.
The Windows installation method requires more complicated steps with the use of S.D.K. and settings of Android Studio I.D.E. .
Here are the steps you need to follow for a default installation.
[mythcat@fedora ~]$ mkdir ~/FlutterProjects
[mythcat@fedora ~]$ cd FlutterProjects/

[mythcat@fedora FlutterProjects]$ ./flutter/bin/flutter doctor

News : SELinux wizzard tool !

I found today in Fedora linux this tool for SELinux with a GUI that allows creating linux security policies.
I will write a little about this system because it is a very good solution.
When I started studying selinux, it was not very well implemented and it seems that the interest of users to be protected is higher.
As you well know, the starting points are network security and data protection and kernel-level intrusions into software.
For those who don't know, SELinux is a system that allows limiting defined resources and allowing other actions or not.
I tested the tool and I can say that it solves only the standard file creation part without the possibility of selecting the SELinux bools variables.
If the one who created this tool will continue to be a very good tool.
It's currently a wizzard interface, I'd call it a Node Editor to allow the assembly of different processing blocks (nodes) into combinations that feed data to each other along connections you specify to produce complex effects.
After completing the steps in the wizard, you will have some default files.
I used the name firefox because the security of the browser is very low at the moment.
Here are some images of this tool:

News : ... about new about Google Analytics 4.

I found at Google.com analytics academy this message that urges us to go through the courses from the skillshop.exceedlms.com website.
It seems to pass this is quite important if they offered free courses:
These courses are about Universal Analytics. Starting July 1, 2023, standard UA properties will stop processing data (July 1, 2024 for UA 360 properties). Learn about Google Analytics 4, our next-generation measurement solution, with these free courses on Skillshop.

News : VirtualBox 7.0.14 released! from Oracle.

Oracle today released a 7.0 maintenance release which improves stability and fixes regressions. See the Changelog
I also use a version of Fedora running on VirtualBox for tests and rapid development.
Most use Linux on older hardware as a backup OS...
You can use Linux with specific non-default settings for good security of the operating system, but it does not make it invincible.
I don't know if VirtualBox solved the resize of the virtual partition - this was the last issue I encountered with this tool, but it is useful if you want to test something quickly.

News : About my work and one of my websites.

I would like to bring to the attention of those who follow my activity on my websites and appreciate the inability to continue with one of the websites: free-tutorials.org. It is currently hosted on a free host, but I cannot import it 100%, which has led me not to complete it with new posts. The continuation of the activities there, considering the limited time, will be carried out on my blogs with the defined theme with which I started: Linux - Fedora, Graphics, Python, Pygame.
In the meantime, because the host is expensive and until now someone has helped me to host it on his server, it is possible to sell the domain: free-tutorials.org - I receive purchase offers at my personal Yahoo email address catafest@yahoo.com.
Minimum starting price 250 euros, because the domain is old from 2018.

News : The new DNF5 tool is on Fedora .

The new DNF5 will provide a significant improvement in user experiences and performance. The replacement is the second step in upgrade of Fedora Software Management stack. Without the change there will be multiple software management tool (DNF5, old Microdnf, PackageKit, and DNF) based on different libraries (libdnf, libdnf5), providing a different behavior, and not sharing a history and module state. We can also expect that DNF will have only limited support from upstream. The DNF5 development was announced on Fedora-Devel list in 2020.
You can read more on the official webpage on Fedora area.

News: Fedora 36 beta released.

Fedora 36 beta was released and I tested it today.
First of all, Fedora 36 is still in pre-release mode and you should be careful to back up your data before upgrading it has a rollback option just in case.
I haven't seen any significant differences in browsing, and overall it seems faster.
The upgrade commands are the same but the installation process seems more complex.
# dnf upgrade --refresh
# dnf autoremove
# dnf install dnf-plugin-system-upgrade -y
# dnf system-upgrade download --releasever=36 --allowerasing
# dnf system-upgrade reboot
# cat /etc/os-release 
Let's fix the install process:
# dnf system-upgrade clean
# symlinks -r -d /usr 
This is ascreenshot take on my HP Compaq 6710b laptop, you can see the Workstation Edition Prerelease.

Fedora 35 : New Krita version 5.0.0 released.

Today I tested the new released version 5.0.0 for Krita software.
I download the AppImage from the official website.
After download you need to use these commands:
[mythcat@fedora ~]$ chmod +x krita-5.0.0-x86_64.appimage
[mythcat@fedora ~]$ ./krita-5.0.0-x86_64.appimage

The Krita software runs well on the old HP Compaq 6710b, but I recommend better hardware because it is a software for graphic activities.
Don't worry about the message is a database change warning message.

Fedora 29 : the new Fedora 29.

It has been announced for some time to launch Fedora.
Today I have appeared on the interface the possibility to change the old Fedora 28 to Fedora 29.
The interface appeared and I had to click the Download button and then the Install button.
The download process was fast. If you do not have enough disk space then the installation will not work.
After you click the Install button, the installation process will take care of the installation.
Finally, a reset of the distribution will start the new Fedora 29.
I have not found any irregularities or operating problems.
From now on, my posts, tests, and tutorials will be with Fedora 29.
