pitch perfect is a tool for generating and playing audio tones. The mouse controls pitch and volume, while the keyboard allows persistent notes to be added for chord structure. A separate mode toggles between full note interpolation (off-key) and chromatic notes. It currently supports three common waveforms, in addition to allowing short .wav samples to be played.
Pkviz is a tool for plotting and cycling through and animating a series of network packets captured by tcpdump. What makes it unique is that the packets’ structure is visualized, not any labels and not time itself. Pkviz takes each byte in a packet and plots it out end-to-end, left-to-right, from the first byte to the last. How high the dot gets plotted depends on the value of the byte: bytes with a value of 0 are at the bottom and those which are 255 (0xff) – the maximum value of a byte – get plotted at the top. This might not be interesting for one packet, but that changes when you start looking at thousands of packets. Pkviz can cycle through thousands of packets in the set so you can see what happened on the wire.
pmbw is a set of assembler routines to measure the parallel memory (cache and RAM) bandwidth of modern multi-core machines. Memory bandwidth is one of the key performance factors of any computer system. Today, measuring the memory performance often gives a more realistic view of the overall speed of a machine than pure arithmetic or floating-point benchmarks. pmbw contains a set of very basic functions which are all hand-coded in assembler to avoid any compiler optimizations. These basic functions are modeled after the basic inner loops found in any data processing, sequential scanning and pure random access. Any application will have a memory access pattern which is somewhere between these two extremes. The current version of pmbw supports benchmarking 16-, 32-, 64-, 128-, or 256-bit memory transfers on x86_32-bit, x86_64-bit, and ARMv6 systems.
pmcyg is a tool for creating customized collections of Cygwin packages together with the Cygwin installer. This enables self-contained distributions to be created without having to mirror the entire set of Cygwin packages. For example, it can create a single CD-ROM or DVD from which a personalized version of Cygwin can be installed on machines not connected to the Web. A basic installer can be created in less than 25MB; a full set of Cygwin packages might fill a DVD-ROM; or a selection of packages can be constructed to suit your chosen installation medium. pmcyg will then download these and all their dependencies automatically. pmcyg can be used either as a command-line script or via a simple graphical interface.
POSNUMCON is a command-line (or console mode) program for converting between positional numeral systems written in C++. It is able to convert between any positional numeral system (e.g. decimal, octal, binary and hexadecimal) with base (radix) between 2-36 (there is the possibility for extension). It offers full support for big length, negative, and floating-point (fractional) numbers, saving calculation results to a text file. It is fully and easily customizable.
Postbix is a plugin designed to work with Zabbix Enterprise Monitor to provide multi-tiered monitoring and performance and availability reporting and measurement for PostgreSQL databases, along with server performance metrics. It provides an effective mechanism to acquire data from numerous PostgreSQL instances, and in turn provides this information for monitoring and performance metrics to your Zabbix server. You can then utilise the reporting capabilities of Zabbix for all data collected, and provide analysis such as graphs and service-level agreement metrics for stakeholders. The current distribution contains a set of pre-defined templates that incorporate alerting and graphing capabilities from initial deployment. However, these can be fine tuned to suit your needs and data/monitoring requirements.
