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

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)
...
Installing collected packages: rfc3986, anyio, typing-extensions, httpcore, dnspython, async-timeout, pydantic, httpx, 
email-validator, blinker, asgiref, aiosmtplib, aioredis, flask-mailing
    Running setup.py install for blinker ... done
Successfully installed aioredis-2.0.0 aiosmtplib-1.1.6 anyio-3.4.0 asgiref-3.4.1 async-timeout-4.0.2 blinker-1.4 dnspython-2.1.0
email-validator-1.1.3 flask-mailing-0.0.5 httpcore-0.14.3 httpx-0.21.1 pydantic-1.8.2 rfc3986-1.5.0 typing-extensions-4.0.1
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.

 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 319-368-265
 ...
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:
