Z80~Ex is a portable ZiLOG Z80 CPU emulator designed as a library. Goals include precise opcode emulation (documented and undocumented), exact timings for each opcode (including I/O operations), and ability to emulate several virtual CPUs simultaneously. A Z80 code dissasembler is also included.
zFeeder is a simple, customizable, RSS feed reader (aggregator) to integrate news from syndication pages on your Website, wapsite, or intranet. It can be integrated with other CMS or weblog management systems and is template driven. It supports all versions of RSS (0.9, 0.9x, 1.0 and 2. 0). It caches XML files, and features an administration panel, the ability to import/export OPML subscriptions lists, online/offline refreshing of feeds via a browser or cron, and multiple categories.
The zen Platform is a Java development environment for J2SE/J2EE. It eases and accelerates the Java application development by visual methods (RAD). Complete applications can be modelled in an intuitive fashion without the need for technical expertise. The complexity of Java and J2EE programming is tremendously hidden - reducing the learning curve for Java novices. Java experts are by no means restricted - they may apply their knowledge without limitations. Application flexibility is a core feature of the platform, which is delivered as an Eclipse plugin.
zend-db-model-generator is a PHP script that reads the structure of a requested table and generates proper table, model, and mapper classes with all the relevant setters and getters using the Zend FrameWork. This script adds several functions to make it easier to work with a database like Zend_Paginator, Zend framework referenceMap, and other useful functions.
The zeroer utility can be used to wipe empty space on a disk. In contrary to dd, zeroer does not wipe existing files on a partition. It overwrites the unallocated disk spa ce around existing files, which means that deleted files cannot be restored after processing a certain partition with zeroer. The utility's principle consists in writing huge zero-padded memory blocks to a file. To a certain extent, this works similar to dd, but zeroer dynamically reduces the blockwriter's buffer size when the filesystem is going to be full.
zip-center accepts n ZIP codes on the command line. It converts these ZIP codes to latitude and longitude, averages them separately, finds a ZIP code whose center is nearest the lat/lon center point, and computes the distance of each input zip code from the resulting centrally-located zip code in miles (taking into account the variable width of longitudinal differences). This allows a caller of the script to do things like pick a centrally-located venue for a meeting given the ZIP codes of the prospective attendees.
zlib is designed to be a free, general-purpose, legally unencumbered, lossless data-compression library for use on virtually any computer hardware and operating system. The zlib data format is itself portable across platforms. Unlike the LZW compression method used in Unix compress(1), the compression method currently used in zlib essentially never expands the data. (LZW can double or triple the file size in extreme cases.) zlib's memory footprint is also independent of the input data and can be reduced, if necessary, at some cost in compression.
