The Specio distribution provides classes for representing type constraints and coercion, along with syntax sugar for declaring them. Note that this is not a proper type system for Perl. Nothing in this distribution will magically make the Perl interpreter start checking a value's type on assignment to a variable. In fact, there's no built-in way to apply a type to a variable at all. Instead, you can explicitly check a value against a type, and optionally coerce values to that type. The author's long-term goal is to replace Moose's built-in types and MooseX::Types with this module.

Twisted is an asynchronous networking framework written in python. It is used by most of the servers, clients and protocols that are part of other Twisted projects. - twisted.cred, a pluggable authentication system for servers; - twisted.enterprise, an asynchronous adapter of Python DB-API 2.0 database interfaces; - twisted.internet, the Twisted event loop; - twisted.manhole, a debugging service; - twisted.persisted, a collection of object persistence systems - twisted.protocols, a collection of simple network protocols and helper utilities; - twisted.python, a set of Twisted programming abstractions; - twisted.spread, a network transport, serializer and object broker; - twisted.trial, a unit-testing framework; and

Twisted Names is both a domain name server as well as a client resolver library. Twisted Names comes with an "out of the box" nameserver which can read most BIND-syntax zone files as well as a simple Python-based configuration format. Twisted Names can act as an authoritative server, perform zone transfers from a master to act as a secondary, act as a caching nameserver, or any combination of these. Twisted Names' client resolver library provides functions to query for all commonly used record types as well as a replacement for the blocking gethostbyname() function provided by the Python stdlib socket module. Twisted Names is available under the MIT Free Software licence.

GLE is a graphics language that produces PostScript, EPS, PDF, PNG, or JPG ouput from a simple script file. GLE is a full featured scripting language that includes variables, subroutines, logic control, looping, a graphing tool, and more to produce high quality output. It has a full range of facilities for producing publication-quality graphs, diagrams, posters and slides. GLE provides LaTeX quality fonts together with a flexible graphics module, which allows the user to specify any feature of a graph (down to the line width of the subticks, for example).

Netpbm is a toolkit for conversion of images between a variety of different formats, as well as to allow a few basic image operations. Netpbm is based on the widely spread Pbmplus package (release: 10 Dec 91). On top of that, a lot of improvements and additions have been made. After the latest release of Pbmplus, a lot of additional filters have been circulating on the net. The aim of Netpbm was, to collect these and to turn them into a package. This work has been performed by a group of programmers all over the world.

Netdisco is a web-based network management tool designed for network administrators. Data is collected into a PostgreSQL database using SNMP. Some of the things you can do with Netdisco: Locate a machine on the network by MAC or IP and show the switch port it lives at Turn off a switch port, or change the VLAN or PoE status of a port Inventory your network hardware by model, vendor, software and operating system Pretty pictures of your network App::Netdisco provides a web frontend with built-in web server, and a backend daemon to handle interactive requests such as changing port or device properties.

Poly1305-AES is a state-of-the-art secret-key message-authentication code suitable for a wide variety of applications. Poly1305-AES computes a 16-byte authenticator of a message of any length, using a 16-byte nonce (unique message number) and a 32-byte secret key. Attackers can't modify or forge messages if the message sender transmits an authenticator along with each message and the message receiver checks each authenticator. There's a mailing list for Poly1305-AES discussions. To subscribe, send an empty message to poly1305-subscribe@list.cr.yp.to.

Webfwlog is a flexible web-based analysis and reporting tool for firewall logs. It supports log files in standard ipfilter or ipfw format. With Webfwlog you can design reports to use on your firewall logs in whatever configuration you desire. Included are example reports as a starting point. You can sort a report with a single click, "drill-down" on the reports all the way to the packet level, and save your reports for later use. You can also create a link directly to any saved report. Webfwlog requires a web server with PHP support and a MySQL or PostgresSQL database server.

Text_Highlighter is a package for syntax highlighting. It provides a base class provining all the functionality, and a descendent classes geneator class. The main idea is to simplify creation of subclasses implementing syntax highlighting for particular language. Subclasses do not implement any new functioanality, they just provide syntax highlighting rules. The rules sources are in XML format. To create a highlighter for a language, there is no need to code a new class manually. Simply describe the rules in XML file and use Text_Highlighter_Generator to create a new class.

Pygments is a syntax highlighting package written in Python. It is a generic syntax highlighter for general use in all kinds of software such as forum systems, wikis or other applications that need to prettify source code. Highlights are: * a wide range of common languages and markup formats is supported * special attention is paid to details, increasing quality by a fair amount * support for new languages and formats are added easily * a number of output formats, presently HTML, LaTeX, RTF and ANSI sequences * it is usable as a command-line tool and as a library
