What language is it?

The code that you saw it written in Assembly for ARM64 linux and the code is a simple hello world like program printing my username.

Explanation of the code

.section .data
    msg:
        .ascii \"0x4248\\n\" // The string to print
        len = . - msg        // Len is the length of the string in bytes

.section .text
    .globl _start            // The entry point of the program

_start:
    mov x0, 1               // File descriptor 1 is stdout    
    ldr x1, =msg            // Load the address of the string into x1
    ldr x2, =len            // Load the length of the string into x2
    mov x8, 64              // syscall number for write
    svc 0                   // Make the syscall
    mov x8, 93              // syscall number for exit 
    mov x0, 0               // Exit status 0
    svc 0                   // Make the syscall

How to compile and run the code

To compile the code you will need to have a cross compiler for ARM64 linux installed on your system. You can get one from here. Once you have the compiler installed you can compile the code with the following command:

aarch64-linux-gnu-as -o hello.o hello.s
aarch64-linux-gnu-ld -o hello hello.o

Once you have compiled the code you can run it with the following command:

qemu-aarch64 hello

And you should see the output:

0x4248
