Performance Co-Pilot (PCP) is a framework and set of services for supporting system-level performance monitoring and performance management. It provides a unifying abstraction for all of the interesting performance data in a system, and allows client applications to easily retrieve and process any subset of that data using a single API. A client-server architecture allows multiple clients to monitor the same host, and a single client to monitor multiple hosts. Archive logging and replay are integrated so that a client application can use the same API to process real-time data from a host or historical data from an archive.
Inspired by dd5sum, ddsum includes the following features: support for md5, sha1, sha224, sha256, sha384 and sha512 (plus any additional digests provided by OpenSSL); the ability to read source data and write it out while computing a message digest; the ability to compute multiple message digests with one pass of the source data; and the ability to verify that a message digest matches the data you have.
libhid is a user-space HID access library. It provides a generic and flexible way to access and interact with USB HID devices, much like libusb does for plain USB devices. It is based on libusb, thus it requires no HID support in the kernel. Furthermore, it aims to support all operating system supported by libusb: Linux, BSD, OS X, and Windows. Python bindings are provided, and other high-level bindings are available upon request.
FreePlot is a simple mathematical program that plots 2D functions written in Python. It provides an easy-to-use interface and a powerful graphing mechanism that allows the user to understand what she is doing at all times. FreePlot features out-of-the-box multiplatform support for GNU/Linux, BSD, Win32, and MacOS. Functions can be saved to an image file. An unlimited number of functions can be used on the same cartesian plane. Multiple colors, multiple line styles and marks, and legends are supported.
