I am creating a code to be able to print text on the screen with the rust macro (asm!) and this is the code:

fn printmsg(string: &str) {
    let length: usize = string.len();
    unsafe {
        asm!("syscall" :: "{rax}"(1), "{rdi}"(1), "{rsi}"(&string), "{rdx}"(length));
    }
}

fn main() {
    let s = "hello world!";
    printmsg(s);
}

When I run the code it prints random letters...

How do I get it to print "hello world!" and not something else?

Here I have the code:

function request(data) {
...
    var result;
    var req = fetch(url).then((resp) => resp.json()).then(function(dat) {
        result = dat[0][0][0];
    return result;
})

r = request("...")
// Aqui ^ obtengo "undefined"

What I want is to save the value dat[0][0][0]and then return it, to use it again. Can somebody help me?

I was creating a python script using keras in termux with theano as backend, because I can't install tensorflow on android, when I run it I get:

Using Theano backend

How do I solve or hide these warnings?

Here I leave all the files:

~/.keras/keras.json

{
    "floatx": "float32",
    "epsilon": 1e-07,
    "backend": "theano",
    "image_data_format": "channels_last"
}

~/nn.py

import keras
import numpy as np

model = keras.models.Sequential([
    keras.layers.Dense(1, input_dim=1)
])

mse = keras.losses.mean_squared_error
sgd = keras.optimizers.SGD(lr=0.01, momentum=0.9, nesterov=True)

model.compile(loss=mse, optimizer=sgd)

x = np.array([1, 2, 3, 4, 5])
y = np.array([1, 3, 5, 7, 9])

model.fit(x, y, epochs=5, batch_size=1)
result = model.predict([6])
print(int(round(result[0][0])))

It doesn't exist or I don't know where .theanorc is

Python 3.7.1

Keras 2.2.4

Theano 1.0.3

Clang 7.0.0
