AtomicOS – A security-first OS with real crypto and deterministic language

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.

> Claude AI Military Grade - Navy SEAL Level Security

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

kamranjon•7mo ago
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.
SV_BubbleTime•7mo ago
On a side note… agentic AI commit messages have been really great. So I assume he gets that right.
kragen•7mo ago
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?
nyrahul•7mo ago
You had me at "educational operating system"... Let's cut them some slack... Come back after 5 years to check if it still exists.

A security-first OS with real crypto https://github.com/ipenas-cl/AtomicOs/blob/main/kernel/claud...

    /*
     * Claude AI Military Grade - Navy SEAL Level Security
     */
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.

jasinjames•7mo ago
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).

techjamie•7mo ago
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.
