Concrete proposal for async semantics in Swift

Async/Await for Swift

Introduction

Modern Cocoa development involves a lot of asynchronous programming using closures and completion handlers, but these APIs are hard to use. This gets particularly problematic when many asynchronous operations are used, error handling is required, or control flow between asynchronous calls gets complicated. This proposal describes a language extension to make this a lot more natural and less error prone.

This paper introduces a first class Coroutine model to Swift. Functions can opt into to being async, allowing the programmer to compose complex logic involving asynchronous operations, leaving the compiler in charge of producing the necessary closures and state machines to implement that logic.

3 examples of using Async Generators and Async Iteration in JavaScript!
// Create a Promise that resolves after ms time
var timer = function(ms) {
return new Promise(resolve => {
setTimeout(resolve, ms);
});
};
// Repeatedly generate a number starting
// from 0 after a random amount of time
var source = async function*() {

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

MATLAB to Julia quick translation/conversion reference guide

A quick and dirty MATLAB to Julia translation/conversion reference guide.

This is not meant as a reference to the language. For that you should read the manual

Important Diferences

The first few are drawn from here

  • Use brackets to index into vectors and matrices, i.e. do v[i] instead of v(i).
  • Array assigment is done by reference, i.e after A = B modifying A will modify B!
  • One dimensional vectors are column vectors by default.
  • [17, 42, 25] and [17;42;25] both create a column vector. To create a row vector do [17 42 25], this is really a 1-by-3 (two-dimensional matrix).

SSH agent forwarding and screen

SSH agent forwarding and screen

When connecting to a remote server via SSH it is often convenient to use SSH agent forwarding so that you don't need a separate keypair on that server for connecting to further servers.

This is enabled by adding the

ForwardAgent yes

option to any of your Host entries in ~/.ssh/config (or alternatively with the -A option). Don't set this option in a wildcard Host * section since any user on the remote server that can bypass file permissions can now als use keys loaded in your SSH agent. So only use this with hosts you trust.

Good setup for MacBook Pro Retina 13" trackpad in Linux/Xorg/X11 (Debian jessie for me). Handles resting thumb and thumb-click-indefinger-drag correctly. Also fixes jerk/jump on very small movements that ought to be precise.
  1. Use xf86-input-mtrack

Debian Jessie (w/ gnome3) uses the "synaptics" xf86 input module as a default. It is very precise but doesn't support "resting thumb" behaviour that you're used to from OSX.

xf86-input-mtrack is an enhancement of xf86-input-multitouch which is configurable. I built it from source from here: https://github.com/BlueDragonX/xf86-input-mtrack But i see that it's also in the debian package repo. So you probably only need to do:

sudo aptitude install xserver-xorg-input-mtrack

I created an override config in /etc/X11/xorg.conf.d/50-synaptics.conf (create the directory if it doesn't exist) which looks like this:
