Adding a deploy user in Linux

(wherever it says, use your server's domain or IP)

Login to new server as root, then add a deploy user

sudo useradd --create-home -s /bin/bash deploy
sudo adduser deploy sudo
sudo adduser deploy admin
sudo passwd deploy

And Update the new password

Deploy Node.js Apps with Flightplan

##Setup your server (this would ideally be done with automated provisioning)

  • add a deploy user with password-less ssh see this gist
  • install forever npm install -g forever

##Install flightplan

  • npm install -g flightplan
  • in your project folder npm install flightplan --save-dev
  • create a flightplan.js file
In your github fork, you need to keep your master branch clean, by clean I mean without any changes, like that you can create at any time a branch from your master. Each time that you want to commit a bug or a feature, you need to create a branch for it, which will be a copy of your master branch.
When you do a pull request on a branch, you can continue to work on another branch and make another pull request on this other branch.
Before creating a new branch, pull the changes from upstream. Your master needs to be up to date.
Create the branch on your local machine and switch in this branch :
<pre>$ git checkout -b [name_of_your_new_branch]</pre>
vaghul / client.js
Created July 27, 2017 08:32 — forked from crtr0/client.js
A simple example of setting-up dynamic "rooms" for clients to join
// set-up a connection between the client and the server
var socket = io.connect();
// let's assume that the client page, once rendered, knows what room it wants to join
var room = "abc123";
socket.on('connect', function() {
// Connected, let's sign-up for to receive messages for this room
socket.emit('room', room);

With the release of iOS 8.0, there is no need for getting an image and blurring it anymore. As Andrew Plummer pointed out, you can use UIVisualEffectView with UIBlurEffect.
UIViewController * contributeViewController = [[UIViewController alloc] init];
UIBlurEffect * blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];
UIVisualEffectView *beView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];
