Sculptor: A Real Time Phase Vocoder
Sculptor is a package that can manipulate sound samples in potentially exciting ways. It has a front end which permits the user to perform these manipulations in real time. System-V IPC has been used to split the process into two halves which can be efficiently load-balanced on a multi-processor machine. The source code is freely available (see Resources).
Sculptor is not intended as a guide to good programming practice; in fact, some of the code is just plain ugly. Early in its development, the whole application was required to work in real time on a 386 machine without a co-processor, so some sacrifice of clarity for speed had to be made. Nonetheless, it is hoped the code might stimulate other projects in real-time audio manipulation, now that one based on a processor-intensive algorithm has been demonstrated to operate fully interactively in real time. The application is also being used to support research into computer music at the University of Leeds, and so by definition will never be “finished”.
Getting Started with DevOps - Including New Data on IT Performance from Puppet Labs 2015 State of DevOps Report

DevOps represents a profound change from the way most IT departments have traditionally worked: from siloed teams and high-anxiety releases to everyone collaborating on uneventful and more frequent releases of higher-quality code. It doesn't matter how large or small an organization is, or even whether it's historically slow moving or risk averse — there are ways to adopt DevOps sanely, and get measurable results in just weeks.
