Whenever you use UNIVERSAL::isa as a function, a kitten using Test::MockObject dies. Normally, the kittens would be helpless, but if they use UNIVERSAL::isa (the module whose docs you are reading), the kittens can live long and prosper. This module replaces UNIVERSAL::isa with a version that makes sure that if it's called as a function on objects which override isa, isa will be called on those objects as a method. In all other cases the real UNIVERSAL::isa is just called directly.

Stone is a TCP/IP packet repeater in the application layer. It repeats TCP and UDP packets from inside to outside of a firewall, or from outside to inside. Stone has following features: 1. Simple. Stone's source code is only 3000 lines long (written in C language), so you can minimize the risk of security holes. 2. Stone supports SSL. Using OpenSSL (http://www.openssl.org/), stone can encrypt/decrypt packets. 3. Stone is a http proxy. Stone can also be a tiny http proxy. 4. POP -> APOP conversion. With stone and a mailer that does not support APOP, you can access to an APOP server.

Supervisor is a client/server system that allows its users to monitor and control a number of processes on UNIX-like operating systems. It shares some of the same goals of programs like launchd, daemontools, and runit. Unlike some of these programs, it is not meant to be run as a substitute for init as "process id 1". Instead it is meant to be used to control processes related to a project or a customer, and is meant to start like any other program at boot time.

TagZilla is an add-on to Mozilla that lets you add a tagline, random or specifically chosen by you, to the end of an email or newsgroup posting, or to the clipboard for pasting into a Web-based email or message board. What is a tagline? A tagline is a one-line joke, witticism, factoid, what have you. It can be about any subject (although it's good to ensure it's appropriate to the forum in question). The random quotes that can be found at the end of web pages like Slashdot or the MozDev home page could be considered taglines.

The TimeDate distribution replaces earlier GetDate distribution, which was only a date parser. The date parser contained in this distribution is far superior to the yacc based parser, and a *lot* faster. The parser contained here will only parse absolute dates, if you want a date parser that can parse relative dates then take a look at the Time modules by David Muir on CPAN. The file Local.pm.new which is included in this distribution is a patched version of Time::Local which comes with perl. It fixes two problems - It determines the zone offset based on now rather than epoch - It fixes a problem with looping forever when a year > 1900 is passed in

Tool to compile and run C programs like a shell script. First of all, this is not the same as tcc. TCC is a compiler. TCC will preform its own set of optimizations, just as GCC will preform its own and Clang will preform its own. The purpose of this script is to give a simple front-end to a compiler. Whether it's GCC, Clang, or something else entirely, one can get to choose their compiler. It's simply satisfying to type c hello.c and see it run instantly. C is fast. Being able to write a small, fast, and portable C "script" is great. One can pass around a C "script" just like s/he would a BASH script.

XORSearch is a program to search for a given string in an XOR or ROL encoded binary file. An XOR encoded binary file is a file where some (or all) bytes have been XORed with a constant value (the key). A ROL (or ROR) encoded file has it bytes rotated by a certain number of bits (the key). XOR and ROL/ROR encoding is used by malware programmers to obfuscate strings like URLs. XORSearch will try all XOR keys (0 to 255) and ROL keys (1 to 7) when searching. I programmed XORSearch to include key 0, because this allows to search in an unencoded binary file (X XOR 0 equals X). If the search string is found, XORSearch will print it until the 0 (byte zero) is encountered or until 50 characters have been printed, which ever comes first. 50 is the default value, it can be changed with option -l. Unprintable characters are replaced by a dot.

clockspeed uses a hardware tick counter to compensate for a persistently fast or slow system clock. Given a few time measurements from a reliable source, it computes and then eliminates the clock skew. sntpclock checks another system's NTP clock, and prints the results in a format suitable for input to clockspeed. sntpclock is the simplest available NTP/SNTP client. taiclock and taiclockd form an even simpler alternative to SNTP. They are suitable for precise time synchronization over a local area network, without the hassles and potential security problems of an NTP server. This version of clockspeed can use the Pentium RDTSC tick counter or the Solaris gethrtime() nanosecond counter. A port to non-i386 platforms was done using the clock_gettime(2) function. Since this is somewhat experimental, there might be some tiny precision differences from the i386 platform versions. You have been warned!

Doscan is a tool to quickly scan your network for machines listening on a TCP port, opening thousands of TCP connections in parallel. Features High scanning rate: five to ten minutes per 100,000 addresses (which are sparsely populated with hosts), with rather conservative timeouts. Load distribution: doscan scans the addresses in a seemingly random order. If your scan host is connected to a central router, this ensures that the load is distributed across your network, and you are stress-testing just a single router, and not your edge devices. Low memory consumption: memory usage is proportional to the number of hosts which have responded so far, and to the number of parallel connections. The total number of addresses does not influence memory usage in any way. Can collect responses: doscan optionally records data which is sent by the hosts which are being scanned. You can even specify a regular expression to extract part of a server banner, and a message to send to trigger a response (great for determining HTTP server versions). Extensibility: It is possible to add special handlers for TCP-based protocols, using a straightforward interface. It supports scanning the vulnerable Microsoft DCOM implementation.

Fudge is a Python module for using fake objects (mocks, stubs, etc) to test real ones. This module is designed for two specific situations: * Replace an object o Temporarily return a canned value for a method or allow a method to be called without affect. * Ensure an object is used correctly o Declare expectations about what methods should be called and what arguments should be sent. Fudge was inspired by Mocha which is a simpler version of jMock. But unlike Mocha, Fudge does not automatically hijack real objects; you explicitly patch them in your test setup. And unlike jMock, Fudge is only as strict about expectations as you want it to be. If you just want to expect a method call without worrying about its arguments or the type of the arguments then you can.
