Assuming a Properly configured DNSMasq

a quickstart for dnsmasq is given at the end if you have not set it up yet.

---

something like this will add a great regularly updated malware file for it to use. More security and privacy to you! Specifically, this uses https://github.com/StevenBlack/hosts Choose one of the Raw Hosts file from there to use.

To setup DNSMasq, follow the below ...

wget -O- https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts | awk '$1 == "0.0.0.0" { print "address=/"$2"/0.0.0.0/"}' > /etc/dnsmasq.d/malware.conf`

Reasons for moving to from MySQL to PostgreSQL

• Anecdotal - overall better DB out-of-the-box. Yes, MySQL can be made strict by tuning its settings but it is still catching up.
• Character collation. Multi-lingual and emoji content necessitates UTF8. In MySQL, the "true" UTF8 is UTF8-MB4. We stumbled on this. PostgreSQL's collation is set to UTF8 OOTB and we had no surprises getting our content in and out.
• Setting collation to utf8mb4 emits an index key length issue in older versions (n-1, n-2, etc.) of MySQL (as of 2017-18). These versions are the default in various Linux distros. To circumvent this, we had to limit indexed string columns to a specific length - which is not ideal. No such issues in PostgreSQL.
• We needed the array data type (available in PostgreSQL) in one of our projects, and it was indexable too! PostgreSQL's JSON data type was also better than MySQL's.

Array.prototype.cmap = function(operation) {
  var output = [];
  for (var i = 0; i < this.length; i++) {
    output[i] = operation(this[i]);
  }
  return output;
}

var addTwo = function (a) {
  return a + 2;

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)
