Running the server

Locally

1. Install Rust >= 1.1.0
2. cargo run

On the Remote Server

1. Install and configure nginx as a reverse HTTP proxy.
2. SCP Rust server app binaries and start on required ports, ie. trumpet -p PORT.

Misc Notes on Speech

Phonemes

• CMU Dictionary, which uses Arpabet.
  • 54 units in the Arpabet:
    • Vowels:
      • 10 monophthongs (AO, AA, IY, UW, EH, IH, UH, AH, AX, AE)
      • 5 diphthongs (EY, AY, OW, AW, OY)
      • 8 R-colored vowels (ER, AXR, EH R, UH R, AO R, AA R, IH|IY R, AW R)
    • Consonants:
      • 6 Stops (P, B, T, D, K, G)
      • 2 Affricates (CH, JH)
      • 9 Fricatives (F, V, TH, DH, S, Z, SH, ZH, HH)
      • 6 Nasals (M, EM, N, EN, NG, ENG)
      • 5 Liquids (L, EL, R, DX, MX)
      • 3 Semivowels (Y, W, Q)

Diphones

TODO: Generate a list of phoneme 2-tuples.

Unit Selection

• Combine multiple sources into final output (words, phonemes, diphones)
• Have alternatives (words, phonemes) that pair better with others.
• Optimize joining on a score (start/ending pitch, tempo, etc.)

Production Server

The production server is 209.239.112.74.

I'm using nginx as a reverse HTTP proxy.

To manage the process, sudo service nginx restart, etc.

To see what processes bind a port, sudo lsof -i:80, etc.

Current nginx config

In sites-available, at /etc/nginx/sites-enabled/default,

server {
  # XXX: Note - port 9000 is a temporary artifact; normally port 80.
  listen 9000;
  server_name jungle.horse;
  location / {
    proxy_pass http://127.0.0.1:8888;
  }
}

server {
  listen 9000;
  server_name capitalism.store;
  location / {
    proxy_pass http://127.0.0.1:9999;
  }
}

Old IPTABLES Config

This was the old iptables-based routing. Even after flushing the rules, port 80 still forwards to 9000 for some reason.

The rules were (prior to flush),

bt@colossus960:~$ sudo iptables --list-rules
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
-A INPUT -i eth0 -p tcp -m tcp --dport 80 -j ACCEPT
-A INPUT -i eth0 -p tcp -m tcp --dport 9000 -j ACCEPT

And,

bt@colossus960:~$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:http
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:9000

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

User Creation

1. sudo useradd $NAME
2. sudo mkdir /home/$NAME
3. (copy .bashrc, .profile, .bash_logout to homedir)
4. (chown homedir to new user)
5. sudo chsh -s /bin/bash $NAME
6. sudo passwd $NAME
