Ziproxy is a high-performance forwarding (non-caching) HTTP proxy that gzips text and HTML files, and reduces the size of images by converting them to lower quality JPEGs or JPEG 2000. It is intended to increase the speed for low-speed Internet connections (mobile, dial-up, other). It's suitable for both home and professional usage. Ziproxy is fully configurable and also features transparent proxy mode, HTML/JS/CSS optimization, operation in daemon mode, a detailed access log with compression statistics, basic authentication, and more.
The zisofs filesystem is an extension to the ISO9660 filesystem that allows files, on a file-by-file basis, to be stored compressed and decompressed in real time. The zisofs filesystem is supported by recent versions of Linux (2.4.14 or later). Legacy systems can still read uncompressed files. zisofs-tools contains the tools necessary to create such a compressed ISO9660 filesystem and to read compressed files on a legacy system.
zlcatalog is a C library that can be used to organize information in a non-hierarchical way. It features an XML file structure, elements that can belong to multiple groups, groups that can be sorted by name or date, and an API that provides easy methods of bulding groups from directories, adding/removing groups, adding/removing elements, etc.
zlplay is an MP3 player that uses the zlcatalog system to organize songs. zlcatalog is a library for organizing things in non-hierarchical ways. Songs in zlplay can belong to multiple groups. Navigation through the groups shows songs and related groups. So, for example, it's very easy to start listening to all of your songs randomly and then when you hear a song by a particular artist, a single click switches the song list to songs by that artist.
zmaildrop is a mail delivery agent (MDA) specifically designed to analyze emails, extract relevant information, and send it to a Zabbix server. It is designed for use with schedulers, backup tools, and security monitoring tools that report information via email. As an MDA, it integrates easily with mail transfer agents (MTA) such as Postfix, Exim, and Qmail, or mail retrieving tools as Fetchmail. It is highly configurable, using a simple YAML syntax to describe tool-specific mail formats.
zmeter is a serial interface for the RadioShack 22-812 digital multimeter. It listens to the specified serial port and prints the meter reading on standard output (stdout). It operates by waiting for data from the digital multimeter to appear on the serial port and then passing that data to a child process to be formatted and output. It was derived from slsnif with most of the interesting features cut out and a small amount of original code added to support the 22812 data format.
