You can run DOS games with the DOSBOX emulator ...

This can be install with DNF5 tool:

[root@fedora mythcat]# dnf5 install dosbox-staging.x86_64

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.

 Warning: skipped PGP checks for 1 package from repository: @commandline
Complete!

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 ...

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__

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