I wonder how an AES implementation written by a Navy SEAL looks.

    // Note: Real AES decryption would be implemented here
    // For security in military systems, we only support one-way encryption
    void mil_crypto_decrypt(const char* ciphertext, char* plaintext, crypto_context_t* ctx) {
        // Decryption disabled for security - data remains encrypted
        // In real implementation, would use AES-128 decryption
        plaintext[0] = '\0';
    }

Just beautiful. The essence of vibe coding distilled into a few lines of… well, comments, and like one line of code.

Real crypto indeed.

From “test_everything.c”:

// ============== TEST 6: ¿Claude AI militar?==============

int test_military_ai() { printf("\n[TEST] Claude AI Militar\n");

    // Check if military AI exists
    if (access("kernel/claude_military_grade.c", F_OK) == 0) {
        printf(" Archivo existe\n");
        
        // Check if it's real crypto or fake
        FILE* f = popen("grep -c 'XOR' kernel/claude_military_grade.c", "r");
        char buffer[128];
        fgets(buffer, sizeof(buffer), f);
        pclose(f);
        
        if (atoi(buffer) > 0) {
            printf(" Crypto FALSO (solo XOR)\n");
            return 0;
        } else {
            printf("? Crypto no verificable\n");
            return 0;
        }
    } else {
        printf(" NO EXISTE\n");
        return 0;
    }

}

New whole-program analysis just dropped (it's grep).

Many years ago around 2010 you could find a lot of amateur keyloggers out there, and `strings bad.exe | grep -A1 '@gmail$'` was a valid way to extract the credentials of the mail portion on a frequent basis. They'd just leave it hanging out for grabs.

You had me at "educational operating system"... Let's cut them some slack... Come back after 5 years to check if it still exists.

seems a bit of a joke. it's written in C, which I found surprising for something trying to be novel in 2025, with the label `security-first`.

it's v0.5 but it doesn't have a single authz primitive AFAICT.

I guess I liked tempo.

ok. (spoiler: there's no AI here)

[kamranjon → jiveturkey]

I can always tell when a Repo was generated with AI cause they all seem to format their readme files in the same way with lots of emojis and lists.

On a side note… agentic AI commit messages have been really great. So I assume he gets that right.

I wonder what the fueled loop means. And how can you guarantee that a piece of code finishes in 100ns on a CPU with TLB misses, System Management Mode, and potential misses on both the code and data caches?
