Fedora 37 : Kernel Test Days.

The main goal of a Kernel Test Day is to test a new kernel on many different machines as possible ...

To test the kernel and help the Fedora development team you need to run one tool from Fedora.

I used DNF to install the fedora python package.

[root@fedora kernel-tests]# dnf install python3-fedora.noarch
...
Installed:
  python3-fedora-1.1.1-7.fc37.noarch                                            
  python3-kitchen-1.2.6-14.fc37.noarch                                          
  python3-lockfile-1:0.12.2-8.fc37.noarch                                       
  python3-munch-2.5.0-10.fc37.noarch                                            
  python3-openidc-client-0.6.0-17.20220119git0e2ed81.fc37.noarch                

Complete!

I install the Development Tools group for development issues.

[mythcat@fedora kernel-tests]$ sudo dnf -y groupinstall "Development Tools"

I clone the kernel-tests tool from the GitHub repository.

[mythcat@fedora ~]$ git clone https://pagure.io/kernel-tests.git
Cloning into 'kernel-tests'...

Into the folder kernel-tests set your user and password to send data to the Fedora development team.

[mythcat@fedora ~]$ cd kernel-tests/
[mythcat@fedora kernel-tests]$ cp config.example .config
[mythcat@fedora kernel-tests]$ vi .config

Set the SELinux settings, if this is enabled.

[mythcat@fedora kernel-tests]$ sudo semanage boolean -m --on selinuxuser_execheap

I run both tests, like in the documentation area.

See these results of my tests on HP Compaq 6710b laptop:

[mythcat@fedora kernel-tests]$ sudo ./runtests.sh

Fedora 34 : GitKraken tool.

GitKraken is a freemium, cross-platform Git client. Users must pay to use this product commercially, and with large teams. It isn’t open source. That said, it has a free version that anyone can use (for personal, and hobby reasons).

This tool can be found on this website.

I'm trying to install the rpm package, but I got an error about: does not verify: no digest.

I used this mode:

wget https://release.gitkraken.com/linux/gitkraken-amd64.tar.gz
sudo tar -xvzf gitkraken-amd64.tar.gz

This tool work well, see the next picture:

Fedora 34 : Neix feed reader.

neix is a simple, work in progress terminal feed reader for all common RSS/Atom feeds on the web out there.

Let't install from the GitHub repository.

Fedora 33 : Bash script for GitHub to fix bad commit branch.

One mistake is to have changed in the [master] branch instead of [mymain]. This can be fixed with this bash script:

# check the branch that you committed to by accident, in this case, is master
git checkout master

# reset the branch back one commit
git reset --soft HEAD^

# use stash to record the current state of the working directory
git stash

# checkout the branch it should be in, in this case, is mymain
git checkout mymain

# apply the stash
git stash apply

# commit the changes 
git commit -am "main commit"

# then push the changes to our main branch
git push origin mymain

# checkout the original branch, in this case, is master
git checkout master

# the last step is to force push the commit deletion to the original branch.
git push --force origin master

Hope this help's !!

Fedora 31 : Uploading a repo with Fedora.

This is a simple way to upload to the GitHub website your source code.
First, you need to create your repo on your GitHub account using New button from Your repositories on account area.
Fill with the name of your GitHub project and see the link to your project.
In my case, I used the named project django_chart and the link is https://github.com/catafest/django_chart.git.
In your local folder project from Fedora distro use this commands:

(env) [mythcat@desk django]$ git init
(env) [mythcat@desk django]$ git add .
(env) [mythcat@desk django]$ git commit -m "First Commit"
(env) [mythcat@desk django]$ git remote add origin https://github.com/catafest/django_chart.git
(env) [mythcat@desk django]$ git push -f origin master

This last output tells me the files are on GitHub repo project.

Fedora 30 : First steps with Fedora and GitHub.

In this tutorial I will show you how you can use Fedora and your GitHub account for your projects.
Let's solve this issue in a simple way.
First, you need to install the git tool with dnf tool:

[root@desk mythcat]# dnf -y install git

Let's see the version of this tool with a regular user:

[mythcat@desk ~]$ git --version
git version 2.21.0

Let's set up the user for my GitHub account:

[mythcat@desk ~]$ git config --global user.name "catafest"
[mythcat@desk ~]$ git config --global user.email "catafest@yahoo.com"

You can see it later with this command:

[mythcat@desk ~]$ git config --list
[mythcat@desk ~]$ git config --global --list

I used this commands to create a folder for my git projects:

[mythcat@desk ~]$ mkdir project_github
[mythcat@desk ~]$ cd project_github/ 

Now I can download my GitHub project named flask_yt from here:

[mythcat@desk project_github]$ git clone https://github.com/catafest/flask_yt.git
Cloning into 'flask_yt'...
remote: Enumerating objects: 23, done.
remote: Counting objects: 100% (23/23), done.
remote: Compressing objects: 100% (19/19), done.
remote: Total 23 (delta 1), reused 14 (delta 0), pack-reused 0
Unpacking objects: 100% (23/23), done.

If you don't have one then you can create your new project on your GitHub account. Let's make some changes into README.md file:

[mythcat@desk project_github]$ cd flask_yt/
[mythcat@desk flask_yt]$ vim README.md 
...

Now I can use git tool:

[mythcat@desk flask_yt]$ git status
On branch master
Your branch is up to date with 'origin/master'.

Changes not staged for commit:
  (use "git add ..." to update what will be committed)
  (use "git checkout -- ..." to discard changes in working directory)

        modified:   README.md

no changes added to commit (use "git add" and/or "git commit -a")
[mythcat@desk flask_yt]$ git add *
[mythcat@desk flask_yt]$ git commit -m "first commit"
[master 56f1e53] first commit
 1 file changed, 1 insertion(+)

Now I can use my username and password from GitHub when I run this command:

[mythcat@desk flask_yt]$ git push origin master

The changes from README.md will be send to my GitHub website.
