Fedora 42 : Testing isoimagewriter.

Today I tested the isoimagewriter tool on Fedora 42 and works well:
[mythcat@fedora ~]$ sudo fdisk -l /dev/sdb
Disk /dev/sdb: 984 MiB, 1031798784 bytes, 2015232 sectors
Disk model: USB FLASH DRIVE 
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000
[mythcat@fedora ~]$ isoimagewriter 
[mythcat@fedora ~]$ sudo file -s /dev/sdb
/dev/sdb: ISO 9660 CD-ROM filesystem data 'CorePure64' (bootable)
[mythcat@fedora ~]$ sudo qemu-system-x86_64 -cdrom /dev/sdb 
I used an linux iso image from CorePure64

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:
Repositories loaded.

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:

[mythcat@fedora DuneII]$ dunelegacy

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 ...

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

-rwxrw----. 1 mythcat mythcat 1589092 Oct  4 23:55 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__
00009010 T __bss_start
00009010 T __bss_start__
00009010 T __data_start

00009010 T __end__
00009010 T _end
00080000 B _stack
00008000 T _start
[mythcat@fedora ARMProjects]$ objdump -f hello.o

hello.o:     file format elf32-little
architecture: UNKNOWN!, flags 0x00000112:
EXEC_P, HAS_SYMS, D_PAGED
start address 0x00008000

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.
