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:

Fedora 36 : Use the ykman tool - part 001.

You can see a full tutorial about how can install this linux tool for yubikey device on this tutorial.

The next command will program a random 38 character long static password to slot 1 on the device:

# ykman otp static 1 --generate --length 38 --force --keyboard-layout US

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

Last metadata expiration check: 1:21:05 ago on Sat 22 Jan 2022 06:05:54 PM EET.
Dependencies resolved.
...
Complete!

After install I run well with this software:

[mythcat@fedora ~]$ kdenlive

This is a screenshot of the running program:

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.

After installation, you can search and find the installation and Roblox Player and Roblox Studio.

Fedora 35 : OBS Studio tool.

This is a free and open-source software for video recording and live streaming for Linux, Mac, and Windows.

You can download it from the official webpage.

This software can be install with the DNF tool:

[mythcat@fedora ~]$ sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

If you have an old laptop with an old graphic card then this software will not work.

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.

Fedora 35 : Python and Flask-Mailing on Fedora.

First of all, a Merry Christmas to the users and the Fedora team. Python version 3.10.1 works very well on Fedore 35 and today I tested a packet called: Flask_Mailing.

Flask-Mailing adds SMTP mail sending to your Flask applications., see the Github repo.

Let's start with the installation of this packet with the pip utility.

[mythcat@fedora ~]$ pip install -U flask-mailing
Defaulting to user installation because normal site-packages is not writeable
Collecting flask-mailing
  Downloading Flask_Mailing-0.0.5-py3-none-any.whl (15 kB)

I create a folder named ExempleFlask001:

[mythcat@fedora ~]$ mkdir ExempleFlask001
[mythcat@fedora ~]$ cd ExempleFlask001/
[mythcat@fedora ExempleFlask001]$ vi flask001.py

I created the simplest example to test through the import procedure and then read with the dir function, here is the source code:

from flask import Flask
from flask_mailing import Mail, Message

app = Flask(__name__)
@app.route("/")
def index():
    test = str(dir(Mail))
    return test
if __name__ == "__main__":
    app.run(debug=True)

The result of running the script on the command line:

[mythcat@fedora ExempleFlask001]$ python flask001.py
 * Serving Flask app 'flask001' (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.

The browser's response to the script is this:

Fedora 35 : Share your commands online with asciinema tool on blogger.com .

The asciinema.org is now running the latest server and web player code and thus it fully supports this new format.

In the last tutorial about this online tool we briefly presented how it can be used.

In this tutorial, I will present some other features and how you can integrate the result in blogger.com.

Let's see a short example with some simple commands in Linux and how we used this tool:

[mythcat@fedora ~]$ asciinema auth
[mythcat@fedora ~]$ asciinema rec linux_commands_default.cast
asciinema: recording asciicast to linux_commands_default.cast
asciinema: press <ctrl-d> or type "exit" when you're done
[mythcat@fedora ~]$ ls
...
[mythcat@fedora ~]$ dir
...
[mythcat@fedora ~]$ pwd
...
[mythcat@fedora ~]$
exit
asciinema: recording finished
asciinema: asciicast saved to linux_commands_default.cast
[mythcat@fedora ~]$ asciinema upload linux_commands_default.cast

I used the local recording and uploaded it later to avoid additional fixes in case of errors and inconsistencies with what we want to display online.

The asciinema online tool supports sharing an asciicast on Twitter, Slack, Facebook, Google+, or any other site which supports one of these APIs: oEmbed, Open Graph, and Twitter Card APIs, see also this webpage.

To use this online tool with your blog, you will need to use the three lines of source code to change according to the number of asciinema uploaded from the URL.

In my example case is this number 455414 from this URL: https://asciinema.org/a/455414/ and the source code for this blog post is shown below:

<script src="https://github.com/asciinema/asciinema-player/releases/download/v2.6.1/asciinema-player.css"/></script>
<script src="https://github.com/asciinema/asciinema-player/releases/download/v2.6.1/asciinema-player.js"/></script>
<script id="asciicast-455414" src="https://asciinema.org/a/455414.js" async></script>

Here is the result of the source code above, it did not work now because I don't add javascript libraries on the script area.

Fedora 35 : You can test Fedora online.

You can test any Linux on this website.

I tested with Fedora 35 Linux distro and works well.

Just open the website select your Linux distro and press the Start button.

See the nest message on the webpage"

If no window has opened yet please click here: Open VNC-Viewer (allow POP-UPs !)

I used this option and I get the Linux distro for the first install.

I start it without install on the hard disk and this is the result:

Fedora 35 : PlaneShift online game.

On November 13, 2021, the PlaneShift team announces:

We are happy to share a new server is available thanks to Proact, our sponsor! Proact is a data management specialist company focusing on protecting and maintaining companies data.

As you well know:

PlaneShift is a Free Massive Multiplayer Online Role Playing Game, completely made and maintained by volunteers.

Today I tested this game on a laptop model HP Compaq 6710b installed with Fedora 35 Linux distro.

Here is the result:
