Fedora 36 : first steps with the Hy.

Hy is a dialect of the Lisp programming language designed to interact with Python by translating s-expressions into Python's abstract syntax tree (AST). Hy was introduced at Python Conference (PyCon) 2013 by Paul Tagliamonte.
This is quite similar to the old GIMP Script Fu that I've worked with in the past. The syntax assumes a join like tabs in HTML, only we'll use parentheses. I haven't studied in detail the implications it has with the python language, but it certainly wasn't invented for nothing.
First, you need to install it with the pip tool.
[mythcat@fedora ~]$ pip3 install hy --user
Collecting hy
...
Successfully built hy
Installing collected packages: funcparserlib, colorama, hy
Successfully installed colorama-0.4.5 funcparserlib-1.0.0 hy-0.24.0
The I test some examples:
[mythcat@fedora ~]$ hy
Hy 0.24.0 using CPython(main) 3.10.5 on Linux
=> (setv a 1)
=> "hello world"
"hello world"
=> (setv mylist [1 2 3])

=> (get mylist 0)
1
=> (defn greet [name]
...  "Hello "
...  (print "Hello " name))
=> (greet "mythcat")
Hello  mythcat
You can test it online with this online tool:

Fedora 36 : Fill out this survey for a badge.

I've always liked Fedora distro because it applies a concept of interactivity between developers and users.
Even if not everything works, you can see the progress made from the older versions.
Today I completed my feedback in a survey requested by them and I also got a small badget for my effort.
You can find it on this webpage.

Fedora 36 : Inkscape 1.2 with Huion WH 1409 graphic tablet.

In this tutorial I will show you how to install and use the Huion WH 1409 graphics tablet with the new release of Inkscape 1.2 software.
You will need to use the DKMS feature of the kernel and the tablet-specific drivers.
Let's start with the following command to get the driver and show the files:
[root@fedora mythcat]# git clone https://github.com/DIGImend/digimend-kernel-drivers.git
Cloning into 'digimend-kernel-drivers'...

digimend-debug    hid-rebind        hid-viewsonic.c
dkms.conf    hid-uclogic-core.c  Makefile
Let's create it using the command
[root@fedora digimend-kernel-drivers]# make dkms_install
...

dkms add .
Creating symlink /var/lib/dkms/digimend/11/source -> /usr/src/digimend-11
dkms build digimend/11

cleaning build area...
make -j1 KERNELRELEASE=5.17.9-300.fc36.x86_64 KVERSION=5.17.9-300.fc36.x86_64...
...
Let's check and reboot.
[root@fedora digimend-kernel-drivers]# dkms status
digimend/11, 5.17.9-300.fc36.x86_64, x86_64: installed (original_module exists)
[root@fedora digimend-kernel-drivers]# reboot
After rebooting the diver must be activated and you will see that Linux responds to the movement of the tablet pen.
[root@fedora mythcat]# modprobe -r hid-kye hid-uclogic hid-viewsonic
Install the latest version of inkscape 1.2 using the DNF utility.
Start the inkscape software:
[mythcat@fedora ~]$ inkscape
static bool Inkscape::UI::Dialog::DialogContainer::recreate_dialogs_from_state(InkscapeWindow*, const Glib::KeyFile*): Key
file does not have group “Windows”
Gdk-Message: 15:09:10.534: Error flushing display: Broken pipe
It seems that inkscape does not detect and set the tablet if you use the settings of this software, but you can use the tablet with this software even if you do not set it.

Fedora 36 : Install django-hypergen and test it.

Today I test the last version of python version 3.11.0a7 with the Django-hypergen example.
The install process can be found on the GitHub page project.
You can see the full tutorial here.

News: Firefox 100 on Fedora distro.

This new release can download it and read more on the official webpage.
I tested today and as you can see this is working well:

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 : Kdenlive tool.

Note:
The new title of this blog is:About Fedora Linux distro
This was my first blog since blogspot.com and now blogger.com and I wrote my first articles and tutorials using the Linux operating system, especially Fedora distro.
Because I used it so much and it had an impact on my free time. Initially the title was generic "About me and my life" and I later kept it for S.E.O. and because it worked just as well as me.
The new title will not change the content at all and I hope it will come with new and good content.

Let's go back to today's tutorial article: installing kdenlive software.
Kdenlive is a powerful free and open source cross-platform video editing program made by the KDE community.
The last release was on Jan 7, 2022.
I use the DNF utility as follows:
[root@fedora mythcat]# dnf search kdenlive

Fedora 35 : Testing the new Django web framework version 4.0.1 with channels.

Today I tested in Fedora 35 the new version 4.0.1 of the Django framework and the channels package.
Channels augments Django to bring WebSocket, long-poll HTTP, task offloading, and other async support to your code, using familiar Django design patterns and a flexible underlying framework that lets you not only customize behaviors but also write support for your own protocols and needs. see the GitHub website.
The entire tutorial can be viewed on my blog about python programming language.
The result shows that it works with the admin webpage:

Fedora 35 : Roblox Player and Roblox Studio with Grapejuice.

In today's tutorial, I will show you how to install and play Roblox on the Linux Fedora 35 distribution using Grapejuice software.
The Grapejuice software installs protocol handlers to open games from the Roblox website and file handlers to open place files. It also provides a management interface for installing and launching Roblox.
For this, you will need to have a computer with the necessary hardware requirements for this online game.
I tested it on the old HP Compaq 6710b laptop on which I installed Fedora version 35 and it worked very hard.
Here are the Linux commands I used to install.
[mythcat@fedora ~]$ git clone https://gitlab.com/brinkervii/grapejuice

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

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
Old schema: "0.0.10" New schema: 0.0.15
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.
