Comparing XOR between tensorflow and keras
import numpy as np
from keras.models import Sequential
from keras.layers.core import Activation, Dense
training_data = np.array([[0,0],[0,1],[1,0],[1,1]], "float32")
target_data = np.array([[0],[1],[1],[0]], "float32")
model = Sequential()
model.add(Dense(32, input_dim=2, activation='relu'))
model.add(Dense(1, activation='sigmoid'))

A simple example of how to use async/await with hack-lang to perform non-blocking async tasks.
<?hh
async function helloAfter($name, $timeout) {
// sleep asynchronously -- let other async functions do their job
await SleepWaitHandle::create($timeout * 1000000);
echo sprintf("hello %s\n", $name);
}
async function run() {
$joe = helloAfter('Joe', 3);
