AWS SERVER CONFIGURATION

Configuring an Ubuntu AWS Box with Node, Mongodb, and Forever with port forwarding

---

• Login to aws.amazon.com and create an EC2 instance with a standard Ubuntu (14.04) installation.
• Create a Security Group that allows type SSH on port 22 and HTTP on port 80.
• Download the .pem file (during setup) which we'll use to authenticate into your server via terminal.
• Modify permissions on the .pem file downloaded from AWS

$ chmod 0600 ~/Downloads/{your_key}.pem

char inByte;         // incoming serial byte
int count1;           //for some fake data
int count2;     //even more fake data

void setup() {
  // start serial port at 115200 bps:
  Serial.begin(115200);
//  while (!Serial) {
//    ; // wait for serial port to connect. Needed for Leonardo only

###ofGetAppPtr() example

from a .cpp file, for example, "particle.cpp" you can do two things:

• a) include "ofApp.h" (so you know what's inside the ofApp)
• b) cast the ofGetAppPtr as a ptr

you can't include ofApp.h inside another .h file, as you would recursive includes (ie, ofApp includes particle, particle includes ofApp), but putting it in the .cpp is fine.
