Fedora 41 : use pagure tool with ssh key ...

Pagure is a light-weight git-centered forge based on pygit2.

The basic tool can be found on this fedora package, the pagure has more features.

Because I used only like a repo I install with DNF5 tool the basic cli:

# dnf5 install pagure-cli.x86_64

I created a folder then I used easy like git tool for each project I have under basic fedora account:

mythcat@localhost:~/pagure_fedora$ git clone https://pagure.io/mythcat

You need to use ssh-keygen to have a ssh key for pagure on Fedora linux then remove the old key and, add the ssh key to Fedora pagure account, then I push the file:

mythcat@localhost:~/pagure_fedora/mythcat$ ssh-add ~/.ssh/mypagure
mythcat@localhost:~/pagure_fedora/mythcat$ ssh-keygen -y -f ~/.ssh/mypagure
mythcat@localhost:~/pagure_fedora/mythcat$ systemctl restart sshd.service mythcat@localhost:~/pagure_fedora/mythcat$ git push 

For my repo radio-online-catafest the git remote command is this:

mythcat@localhost:~/pagure_fedora/radio-online-catafest$ git remote set-url origin git@pagure.io:radio-online-catafest.git
mythcat@localhost:~/pagure_fedora/radio-online-catafest$ git push 
Everything up-to-date

Fedora 41 : timeshift tool for backup.

... one old tool for backup was rsync ...

Now you have a tool named timeshift with this tool named timeshift and more features ...

You can install with:

root@localhost:/home/mythcat# dnf5 install timeshift.x86_64

I run this tool with :

mythcat@localhost:~$ sudo timeshift-gtk 

The result is this G.U.I. ...

... because the backup is not easy, I search on web and I found a video tutorial from the official youtube channel - DrewHowdenTech

...

Fedora 41 : Minimal gnome install and nemo additionals packages.

I reinstall the Fedora, somehow was crashed with a bad systemd error:

uname -a
Linux localhost.localdomain 6.11.5-300.fc41.x86_64 #1 SMP PREEMPT_DYNAMIC Tue Oct 22 20:11:15 UTC 2024 x86_64 GNU/Linux

If you install nemo with minimal gnome features then you need to install fedora packages, like this one:

root@localhost:/home/mythcat# dnf5 install nemo-image-converter

Fedora 42 : Can be better? part 020.

I wrote in some posts about this blog about the possibility of improving the distribution of Linux Fedora.

Today I discovered that choosing GNOME is a better option with lighting modes and options for the Nemo file manager actions.

I would have wanted to have a better network system similar to portmanager with S.P.N. for fedora users and team on web.

SPN (Secure Peer Name) is a technology related to secure communication protocols, particularly in the context of peer-to-peer networks and distributed systems.

I want to have more tools and applications on tty with GUI, like ncurses... I created an radio online application with ncurses and you can find it on my pagure.

The main goal of these type of graphic user interface is simplicity, no need hardware resources - this HP Compaq 6710b has only 4Gb RAM, and cand be used with Single Board Computer.

I think Fedora don't have a Fedora Spin for Single Board Computer hardware.

Let's start with python 3 action on nemo file manager.

Go to the action folder and create an action file named: python3.nemo_action.

[root@fedora mythcat]# cd /usr/share/nemo/actions
[root@fedora actions]# nano python3.nemo_action

Add this source code :

[Nemo Action]
Name=Execute Python Script
Icon-Name=python
Exec=env /usr/bin/python3 %F
Selection=S
Name[tr]=Python script         
Extensions=py;

Reopen the Nemo file manager and you see an an Execute Python Script, only on the python script on right click menu.

Let's see some screenshots:

Fedora 42 : Testing isoimagewriter.

Today I tested the isoimagewriter tool on Fedora 42 and works well:

[mythcat@fedora ~]$ sudo fdisk -l /dev/sdb

Fedora 42 : Dune Legacy game .

Dune Legacy is an effort by a handful of developers to revitalize the first-ever real-time strategy game.

It tries to be as similar as possible to the original gameplay but to integrate user interface features most modern realtime-strategy games have like selecting multiple units

I download this game from the official website, and I install with DNF5 tool:

[root@fedora Downloads]# dnf5 install dunelegacy-0.96.4.x86_64.rpm
Updating and loading repositories:

Find the orifinal Dune II on web, or try this website.

The game can be start after I unarchive the DuneII archive into DuneII then copy to /usr/share/dunelegacy ...

[mythcat@fedora DuneII]$ sudo su 
[sudo] parola pentru mythcat: 
[root@fedora DuneII]# cp *.* /usr/share/dunelegacy
[root@fedora DuneII]# exit
exit
[mythcat@fedora DuneII]$ dunelegacy 

.. and works well :

Fedora 42 : The cvxpy python module ... part 001.

We are building a CVXPY community on Discord. Join the conversation! CVXPY is an open source Python-embedded modeling language for convex optimization problems. It lets you express your problem in a natural way that follows the math, rather than in the restrictive standard form required by solvers.

Today I install the cvxpy python module ...

You can see on the official website - www.cvxpy.org .

NOTE: I don't understand why the blogger don't have a a code tag , I used a div - pre - code into txt file to wrote my posts ...

[mythcat@fedora ~]$ nano tutoriale.txt

Fedora 42 : First test with red language - part 001.

Red is a next-generation programming language strongly inspired by Rebol, but with a broader field of usage thanks to its native-code compiler, from system programming to high-level scripting and cross-platform reactive GUI, while providing modern support for concurrency, all in a zero-install, zero-config, single ~1MB file!

I download and change to be executable:

[mythcat@fedora ~]$ cd red-lang/
[mythcat@fedora red-lang]$ ls
red-03oct24-920dd0452  red-toolchain-03oct24-920dd0452  red-view-03oct24-920dd0452

I check and install these supporting libraries:

sudo yum install glibc.i686
sudo yum install libcurl.i686
sudo yum install gtk3.i686

I start with the basic intro example from the official website.

Then I need to check the missing files with the DNF tool and install Fedora packages for each error on runtime with executable result

dnf provides \*/libgtk-3.so.0

The result is this:

Fedora 42 : Gnome intro ...

Today I tested the new GNOME environment and these are the screeenshot I get:

Look's good ..., see the tour idea ...

Fedora 42 : Fedora game project with pygame and agentpy - part 004.

... working on hacking game code , you can test two version of the unfinished game with agentpy at my pagure Fedora account.

* Hack the code based on minimal information versus total information. The code has 5 distinct letters. - click on the letters on the keypad - the number of guessed letters is displayed in the form: centered - guessed letters on positions and moved guessed letters but on other positions NOTE: the source code is under development, I need to enter a scroll to be able to enter more codes with letters

Fedora 42 : testing programming for ARM - part 001.

Today I tested the creation of a program that works on ARM processors and tested with QEMU emulator in Fedora 42.

I install with dnf5 these fedora packages:

[root@fedora mythcat]# dnf5 clean all
[root@fedora mythcat]# dnf5 install qemu-system-arm
[root@fedora mythcat]# dnf5 install arm-none-eabi-gcc gcc-arm-linux-gnu gcc-c++-arm-linux-gnu
[root@fedora mythcat]# dnf5 install arm-none-eabi-newlib.noarch 
...
[root@fedora mythcat]# dnf5 install binutils-devel

I create a new folder into may pagure account to test this issue with QEMU:

[mythcat@fedora mythcat]$ mkdir ARMProjects
[mythcat@fedora mythcat]$ cd ARMProjects/
[mythcat@fedora ARMProjects]$ qemu-system-arm --version
QEMU emulator version 9.1.0 (qemu-9.1.0-2.fc42)

I create a default assembly file for ARM named hello.s:

[mythcat@fedora ARMProjects]$ cat hello.s 
.global _start

_start:
    mov r0, #1     
    mov r7, #4     
    str r0, [r7]
    bx lr

Let's see how this means:

global _start: This declares the _start label as global, making it
 accessible from outside the file.
_start:: This marks the beginning of the program.
mov r0, #1: Moves the immediate value 1 into register R0.
mov r7, #4: Moves the immediate value 4 into register R7. This represents the system call number for write().
str r0, [r7]: Stores the contents of R0 (which contains 1) into the memory address pointed to by R7.
bx lr: Branches to the address in Link Register (LR). In this case, it loops indefinitely because there's no return instruction.

The compile of the file:

[mythcat@fedora ARMProjects]$ arm-none-eabi-gcc -nostartfiles -lc hello.s -o hello.o
[mythcat@fedora ARMProjects]$ ls
hello.o  hello.s

Let's see the hello.o file:

[mythcat@fedora ARMProjects]$ nm hello.o
00008000 t $a
00009010 T __bss_end__
00009010 T _bss_end__

Fedora 42 : Fedora game project with pygame and agentpy - part 003.

I have upgraded the source code with the following changes:

• added agent with logic using the python agentpy module;
• I increased the grid to 16 x 16;
• I kept the win condition at 8 pieces aligned in any direction;
• I added conditions for displaying the equality message;

The game is hard to win, you can try on my pagure account.

Fedora 42 : Fedora game project with pygame and agentpy - part 001.

I started a game project with the python packages pygame and agentpy in the Fedora 42 Linux distribution.

I used this version of Fedora:

[mythcat@fedora fedora_game]$ uname -a
Linux fedora 6.11.0-63.fc42.x86_64 #1 SMP PREEMPT_DYNAMIC Sun Sep 15 17:14:12 UTC 2024 x86_64 GNU/Linux

... and this python version:

Python 3.12.3 (main, Apr 17 2024, 00:00:00) [GCC 14.0.1 20240411 (Red Hat 14.0.1-0)] on linux

You can find it on my fedora pagure repo

News : I updated to Fedora 42 .

Few days ago, I updated the Fedora to version 42 on HP Compaq 6710b laptop.

Almost over four thousand Fedora packages have been instaled and reviewed ...

See the result :

$ uname -a
Linux fedora 6.11.0-0.rc7.20240910gitbc83b4d1f086.57.fc42.x86_64 #1 SMP PREEMPT_DYNAMIC Tue Sep 10 15:43:53 UTC 2024 x86_64 GNU/Linux

Fedora 41 : Install portmaster.

Portmaster is a free and open-source application firewall that does the heavy lifting for you. Restore privacy and take back control over all your computer's network activity.

First, download the RPM package from the official website.

Use the dnf5 tool and install it.

The last step is to open, after restart Fedora, see the result on my openbox environment:

Fedora 41 : solving conky default configuration in openbox environment.

I installed Conky on an openbox environment and found an error, it doesn't display upload and download from the network correctly.

I had to use the ifconfig command to see the network interface and then I had to modify the default file.

The default configuration file can be found and edited with any text editor:

[root@fedora mythcat]# nano /etc/conky/conky.conf

Here's how it looks functionally.

-- Conky, a system monitor https://github.com/brndnmtthws/conky
--
-- This configuration file is Lua code. You can write code in here, and it will
-- execute when Conky loads. You can use it to generate your own advanced
-- configurations.
--
-- Try this (remove the `--`):
--
--   print("Loading Conky config")
--
-- For more on Lua, see:
-- https://www.lua.org/pil/contents.html
