Hi there,

Change your MAC address on iOS 7-8

Changing your MAC address can be extremely useful in some situation. Let me give you a few:

• You are limited by time on public networks and everyone want more than just 15 minutes of internet.
• You want to regenerate your UDID
• A lot of governments rely on this to find you and then intercept your datas. In France for example, secret services have full access to public Wi-Fi and therefore can locate you by using your MAC address.

iOS

1. Create a bundle

$ react-native bundle --dev false --entry-file index.ios.js --bundle-output ios/main.jsbundle --platform ios

2. Comment this line in AppDelegate.m,

jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];

DatabaseReference connectedRef = FirebaseDatabase.getInstance().getReference(".info/connected");
connectedRef.addValueEventListener(new ValueEventListener() {
  @Override
  public void onDataChange(DataSnapshot snapshot) {
    boolean connected = snapshot.getValue(Boolean.class);
    if (connected) {
      System.out.println("connected");
    } else {
      System.out.println("not connected");
    }

How to setup Let's Encrypt for Nginx on Ubuntu 16.04 (including IPv6, HTTP/2 and A+ SLL rating)

There are two main modes to run the Let's Encrypt client (called Certbot):

• Standalone: replaces the webserver to respond to ACME challenges
• Webroot: needs your webserver to serve challenges from a known folder.

Webroot is better because it doesn't need to replace Nginx (to bind to port 80).

In the following, we're setting up mydomain.com. HTML is served from /var/www/mydomain, and challenges are served from /var/www/letsencrypt.

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
