Carnifex

Carnifex is a software package to display a live scoreboard for ICPC style contests (with domjudge). It consists of two parts: The server regularly polls all relevant information from domjudge and puts them together in a subscribable network feed. The clients watch this feed and produce a nice anmiated scoreboard out of it.

This software is experimental. Do not use it on critical systems. CHANGE THE SECRET PASSPHRASE before using it on a public network. After decryption input is treated as trusted.

You probably need:

  • protobuf headers
  • a golang toolchain
  • a C++ toolchain
  • Qt5 development files
  • libsodium development files
  • cmake

And at (client) runtime:

  • libprotobuf
  • libsodium
  • libqt5 quick svg
  • DejaVu Sans and Symbola for proper display

The setup currently involves:

  $ export GOPATH="`pwd`"
  $ go get github.com/golang/protobuf/proto github.com/rthornton128/goncurses golang.org/x/crypto/nacl/secretbox golang.org/x/crypto/scrypt
  $ go build server
  $ cmake src/client
  $ make -j4

To start it:

  • put your credentials into credentials.json
  • adjust the server url in config.json
  • put a secret passphrase in config.json
  • possibly adjust server name/api path/port in config.json (see config.README)
  • start ./server
  • start ./client (cannot be started before the server, but will try to reconnect if server is restarted/lost/etc.)

To use it:

  • The resolving mechanism is very basic. It goes forward backward in resolving by left/right arrow keys on the server side (might want to keep it around in a screen/tmux).
  • If the scoreboard is not in resolving phase it normally cycles through all pages periodically, you can pause this and manually move around with space, up and down arrow keys.
