Simple Feedforward Neural Network using TensorFlow
# Implementation of a simple MLP network with one hidden layer. Tested on the iris data set.
# Requires: numpy, sklearn>=0.18.1, tensorflow>=1.0
# NOTE: In order to make the code simple, we rewrite x * W_1 + b_1 = x' * W_1'
# where x' = [x | 1] and W_1' is the matrix W_1 appended with a new row with elements b_1's.
# Similarly, for h * W_2 + b_2

Writing a websocket server in Rust, ran into an issue where the server would hang after a few connection attempts. Here's a minimal client/server; in the server, if you uncomment the separate spawned task on the default scheduler, the hang always happens. Putting that other task on its own thread makes everything work fine.
extern mod extra;
use std::{int,io,result};
use extra::{net,net_tcp,uv};
fn main() {
let (accept_port, accept_chan) = stream();
let (finish_port, finish_chan) = stream();
let addr = extra::net_ip::v4::parse_addr("127.0.0.1");

Mathematics: What do grad students in math do all day?

Mathematics: What do grad students in math do all day?

by Yasha Berchenko-Kogan

A lot of math grad school is reading books and papers and trying to understand what's going on. The difficulty is that reading math is not like reading a mystery thriller, and it's not even like reading a history book or a New York Times article.

The main issue is that, by the time you get to the frontiers of math, the words to describe the concepts don't really exist yet. Communicating these ideas is a bit like trying to explain a vacuum cleaner to someone who has never seen one, except you're only allowed to use words that are four letters long or shorter.

What can you say?
