Regular expressions can be used in the gedit editor using the Find and Replace option with the regular expressions checkbox selected. This can be used to remove empty lines from source code, remove comment lines, replace indexing - if using Python scripts, or replace content. Here's an example of how to remove empty lines from a text using regular expressions:

Fedora 39 : Using a stick or hard disk created in Windows.
When attached to USB, Linux distribution cannot access it.
Install these packages with the DNF utility.
sudo dnf install ntfs-3g
sudo dnf install ntfsfix
Use these commands to create a folder where it will be mounted and test if it can be mounted and where it is viewed :
sudo mkdir /mnt/mydrive
sudo mount -t ntfs-3g /dev/sdb1 /mnt/mydrive
dmesg| grep usb
sudo mount /dev/sdb /mnt/mydrive
df -h
Fix errors with this command
sudo umount /dev/sdb1
sudo ntfsfix /dev/sdb1
It resumes the operation of mounting it in the folder named /mnt/mydrive:
sudo mount -t ntfs-3g /dev/sdb1 /mnt/mydrive
This command will mount as a superuser but can be modified as a normal user.
Create a USB folder into your home folder as normal user.
You can use these commands to use your files like a normal user:
[mythcat@fedora ~]$ sudo mount -t ntfs-3g /dev/sdb1 ~/USB
[sudo] password for mythcat:
...
[mythcat@fedora ~]$ sudo umount /dev/sdb1

Fedora 39 : Fedora 39 Cinnamon environment pre-release - upgrade.
Today I tested the new version of fedora 39 and it worked very well.
If you want to upgrade Fedora using the DNF system upgrade then you can find all information on the official webpage.
You can try a Fedora 39 Cinnamon environment pre-release from this website.
A very good feature comes with this new command remove-retired-packages.
This allow you to keep the all packages with update.

Fedora 37 : Lite editor.
lite is a lightweight text editor written mostly in Lua — it aims to provide something practical, pretty, small and fast, implemented as simply as possible; easy to modify and extend, or to use without doing either.
You can find this project on GitHub.
I install with DNF tool:
# dnf install lite-xl.x86_64
...
Installed:
lite-xl-2.1.1-2.fc38.x86_64
Complete!
... and works very well:
