JACK is a low-latency audio server, written for POSIX conformant operating systems such as GNU/Linux and Apples OS X.

Jack audio connection kit can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as normal applications), or can they can run within the JACK server (ie. as a "plugin").

JACK was designed from the ground up for professional audio work, and its design focuses on two key areas: synchronous execution of all clients, and low latency operation.

Acme::JavaTrace is a Perl module for using Java-like stack traces.

SYNOPSIS

On the command-line:

perl -wMAcme::JavaTrace program_with_strange_errors.pl

Inside a module:

use Acme::JavaTrace;
warn "some kind of non-fatal exception occured";
die "some kind of fatal exception occured";

< buzzword >This module tries to improves the Perl programmer experience by porting the Java paradigm to print stack traces, which is more professional than Perls way. < /buzzword >

This is achieved by modifying the functions warn() and die() in order to replace the standard messages by complete stack traces that precisely indicates how and where the error or warning occurred. Other than this, their use should stay unchanged, even when using die() inside eval().
