>That's hilarious given that Reddit is utterly overrun with blatant, low-quality LLM accounts using ChatGPT to post comments and gain karma, and several of the "text stories" on the front page from subs like AITA are blatant AI slop that the users (or other bots?) are eating up.

Check out this post [1] in which the post includes part of the LLM response ("This kind of story involves classic AITA themes: family drama, boundary-setting, and a “big event” setting, which typically generates a lot of engagement and differing opinions.") and almost no commenter points this out. Hilarious if it weren't so bleak.

Over the past two years, I have also seen many similar stories where the majority of users were unable to recognize that these stories were AI-generated. I fear for the future of democracy if the masses are so easily deceived. Does anyone have any good ideas on how to counteract this?

Usually people create languages to address issues that cannot be addressed by a library because they have different semantics on a deeper level.

Like, Rust could not be a C++ library, that does not make sense. Zig could not be a C library. Julia could not be a Python library.

There is some superficial level of abstraction where all programming languages do is interchangeable computation and therefore everything can be achieved in every language. But that superficial sameness doesn't correspond to the reality of programming.

I agree with your examples, but is there anything new that Mojo brings to the table that could not be achieved with a Python library?

Would love to know which languages you learned that were so similar that you didn't gain much.

Just comparing for example c++, c#, and typescript. These are all c-like, have heavy MS influence, and despite that all have deeply different fundamentals, concepts, use cases, and goals.

I have learned a lot from other programming languages, but developing a new programming language and building an ecosystem around it is a huge amount of work. In the case of the Mojo programming language, it would have been more beneficial to the programming community as a whole if the developers had spent their time improving existing libraries instead of developing a new language.

If a learning a new language didn't change how you think about programming, it wasn't a language worth learning.

threeducks · 5 days ago

Learning new languages did change how I think about programming. For example, Clojure's immutability and functional nature had a strong influence on how I write my (mostly Python) code these days. I learned how to write efficient code for CPUs with C and C++, and for GPUs with CUDA and OpenCL. I learned math with Matlab and Octave, and declarative programming with Prolog.

With Mojo, on the other hand, I think a library (or improvements to an existing library) would have been a better approach. A new language needlessly forks the developer community and duplicates work. But I can see the monetary incentives that made the Mojo developers choose this path, so good for them.

When I was young, I enjoyed messing around with new languages, but as time went on, I realized that there is really very little to be gained through new languages that can not be obtained through a new library, without the massive downside of throwing away most of the ecosystem due to incompatibility. Also, CuPy, Triton and Numba already exist right now and are somewhat mature, at least compared to Mojo.

So are Gemini Flash (Lite) and GPT mini/nano.

Gemini 2.5 Flash Lite and GPT-5 Nano seem to be comparatively slow.

That being said, I can not find non-marketing numbers for Mistral Flash Answers. Real-world tps are likely lower, so this comparison chart is not very fair.

A hash table in C is about 30 lines of code, so I don't think you have to stick to linked lists for dictionaries.

threeducks · 6 days ago

9 lines seem to be sufficient (assuming string keys and int values).

    // Hashtable definition
    #include <string.h>
    #define N 1024
    int* map_ptr(const char **keys, int *values, const char *key){
        size_t h = 0, c = 0, i;
        for (const char *c = key; *c; c++) h = h * 33 + *(unsigned char*)c;
        for (i = h % N; c < N && keys[i] && 0 != strcmp(keys[i], key); i = (i + 1) % N, c++);
        if (!keys[i]) keys[i] = key;
        return 0 == strcmp(keys[i], key) ? &values[i] : NULL;
    }

    // Example usage
    const char *keys[N];
    int values[N];

    #include <stdio.h>

    int main(){
        // Set some values
        *map_ptr(keys, values, "one") = 1;
        *map_ptr(keys, values, "two") = 2;
        *map_ptr(keys, values, "three") = 3;

        // Retrieve values
        printf("one: %i\n", *map_ptr(keys, values, "one"));
        printf("two: %i\n", *map_ptr(keys, values, "two"));
        printf("three: %i\n", *map_ptr(keys, values, "three"));

        return 0;
    }

Interesting. Available in VSCode Copilot for free.

I'm going to test it. My bottleneck currently is waiting for agent to scan/think/apply changes.

threeducks · 12 days ago

I have been testing it since yesterday in VS Code and it seemed fine so far. But I am also happy with all the GPT-4 variants, so YMMV.

I think a lot of really smart people are letting themselves get taken for a ride by the web scraping thing. Unless the bot activity is legitimately hammering your site and causing issues (not saying this isn't happening in some cases), then this mostly amounts to an ideological game of capture the flag. The difference being that you'll never find their flag. The only thing you win by playing is lost time.

The best way to mitigate the load from diffuse, unidentifiable, grey area participants is to have a fast and well engineered web product. This is good news, because your actual human customers would really enjoy this too.

I wonder what all those people are doing that their server can't handle the traffic. Wouldn't a simple IP-based rate limit be sufficient? I only pay $1 per month for my VPS, and even that piece of trash can handle 1000s of requests per second.

    the median prompt [...] consumes 0.24 watt-hours of electricity

In layman's terms, that is (approximately)

- one second of running a toaster, or

- 1/80th of a phone charge,

- lifting 100 pounds to a height of 6 feet,

- muzzle energy of a 9mm bullet,

- driving 6 feet with a Tesla.
