Na so o, we bin dey manage small small.

@thread people, we are having too much talk on this thread and no serious codes, what is going on?

DanielTheGeek:
WTF! I just looked at that guys post on Reddit... You can tell first hand that he didn't write that code if you read his other posts..



That looks 100% like my code so best guess is the book already launched, since said he just started learning Rust recently and he posted that this year... I really have to find that book and in between i'm gonna ask the dude where he copied that from too.. Someone who just learnt Rust can't write a Mandelbrot set just like that, especially in a time when Rust was still a bit partially esoteric...

Someone that can't even compile his program properly, shey na him go come do Mandelbrot program?

DanielTheGeek:
I did a Mandelbrot program in Rust, nothing close to a pixel manipulator but something cool

use std::io::Write;
fn main() {
    let args: Vec<String> = std::env::args().collect( ) ;
    if args.len() != 5 {
        writeln!(std::io::stderr(),
                 "Usage: mandelbrot FILE PIXELS UPPERLEFT LOWERRIGHT " )
            .unwrap();
        writeln!(std::io::stderr(),
                 "Example: {} mandel.png 1000x750 -1.20,0.35 -1,0.20 ",
                 args[0])
            .unwrap( ) ;
        std::process::exit(1 ) ;
    }
    let bounds = parse_pair(&args[2], 'x')
        .expect("error parsing image dimensions" ) ;
    let upper_left = parse_pair(&args[3], ',')
        .expect("error parsing upper left corner point" ) ;
    let lower_right = parse_pair(&args[4], ',')
        .expect("error parsing lower right corner point" );
    let mut pixels = vec![0; bounds.0 * bounds.1] ;
    render(&mut pixels[..], bounds, upper_left, lower_right) ;
    write_bitmap(&args[1], &pixels[..], bounds)
        .expect("error writing PNG file" ) ;
}

Hmn, I cannot help but notice too. . . .I am somewhere else off nairaland battling someone over advantages of xml over json (i am for json, while the other unfortunate dude is for xml - we are still at draws, no winner yet)

DanielTheGeek:
This Is me proving that you can't USE just ANY language

You asked me to throw a challenge in any language I like... If you can't do that simple data partition task the challenge would be null.

I see you like the piece of cake to have opted for Python...

4kings:
Do you know assembly?

rushman003:
This is a challenge and also a problem i'm currently facing! I would have opened another tread but i don't wanna derail

Any of the programmer here to read unformatted / not well formed xml data from a TCP client(socket) and use a particular message string from the xml to trigger an IP camera...

Mind you have got this working on a simulator but the same code is giving problem with the real device!

below is the pull data for the handshake communication between server and client

DanielTheGeek:
Seunthomas can you give this a shot in Glass language? I know it's too simple but just manage it...can't think of much right now or maybe try Crystal..

dhtml118:
This thread is fast deviating to chest-thumping.

DanielTheGeek:
The secret about learning ANY language is in every developer, getting is just the tricky part..

There's a difference between understanding a language and knowing a language. TF! I can keep a list of languages I know coming in till tomorrow.. But the languages I understand in-out aren't more than 5 or 6.. However I think Seunthomas has gotten to the stage where he doesnt need an eBook or video to learn a new language..even i have gotten to that stage and it's not pride, we all learn everyday, every ambitious/serious programmer will get to that stage....all you do is apply your previous knowledge of other languages to work with the new one... As far as you have good knowledge of at least one functional and one object oriented language then picking another language will be a matter of adapting to the syntax and learning the conventions. I will not forget ShedrachOkonofua...one of the finest devs I met on NL, this guy is a real polyglot developer and I respect him much as I respect others in here.

But what I have come to discover in my little years of gaining peanut knowledge is that polyglot developers are the least efficient in the room as devs with a focus on a single language tend to do more, but this is only my opinion/theory...



Does Daniel know the BrainFuck language , Yeah....can he write a simple hello world program in it? Hell no..

DanielTheGeek:
Asalimpo is right and no matter what...whether you get the desired result.. a -0.1ms difference in performance should mean a lot to you. Remember, good companies won't look only for the program that gets the job done but the one that gets it done faster... Good job though.

dhtml118:
It can come back to life, if we want it back to life. This is the first really interesting topic in a long while.

I move the motion that we bring this board to life - what do you say guys?

bolkay47:
Good evening.
You may be right. The solution gets the job done and it took '00:00:00.1405923' which in my opinion is still good....
if you have any other method, you can put it forward.I will be glad to see it.
Can you help me locate the OP?

HarmattanHunter:
You could skip the thread if you have no contribution. Let the great guys speak.

Euler's Totient function, φ(n) [sometimes called the phi function], is used to determine the number of positive numbers less than or equal to n
which are relatively prime to n. For example, as 1, 2, 4, 5, 7, and 8, are all less than nine and relatively prime to nine, φ(9)=6.
The number 1 is considered to be relatively prime to every positive number, so φ(1)=1.
Interestingly, φ(87109)=79180, and it can be seen that 87109 is a permutation of 79180.
Find the value of n, 1 n 107, for which φ(n) is a permutation of n and the ratio n/φ(n) produces a minimum.

I challenge you to building a Machine Learning Library/Solution just like Google machine that detect unusual users login

Build a simple algorithm that converts English to Morse code.

that is a too generic something, it is something that you can get easily on google or wherever.
