Derrick is a simple tool for recording data streams of TCP and UDP traffic. It shares similarities with other network recorders, such as tcpflow and wireshark, though it is more advanced than the first and clearly inferior to the latter. It has been specifically designed to monitor application-layer communication. In contrast to other tools, the application data is logged in a line-based ASCII format. Common Unix tools, such as grep, sed, and awk, can be directly applied. Even replay of recorded communication is straightforward using netcat. Derrick supports on-the-fly compression and rotation of log files.
OGRI (Original Generic Reporting Intranet) provides a simple Web-based interface with "portals" for viewing any number of reports in a secure manner. It is designed to be as lightweight as possible in terms of server load, and its simple interface means it works well with most browsers.
utfout is a command-line tool that can produce UTF-8 (Unicode) strings in various ways and direct them to standard output, standard error, or direct to the terminal without the need for shell support. Strings can be repeated, delayed, randomly-generated, written to arbitrary file descriptors, interspersed with other characters, and generated using ranges. printf(1)-style escape sequences are supported along with extended escape sequences. utfout(1) sits somewhere between echo(1) and printf(1).
Turpentine is a Magento extension to improve Magento's compatibility with Varnish, a very fast caching reverse proxy. By default, Varnish doesn't cache requests with cookies, and Magento sends the frontend cookie with every request, causing a (near) zero hit rate for Varnish's cache. Turpentine provides Varnish configuration files (VCLs) to work with Magento and modifies Magento's behavior to significantly improve the cache hit rate.
