TestU01 is a software library, implemented in the ANSI C language, and offering a collection of utilities for the empirical statistical testing of uniform random number generators. The library implements several types of random number generators in generic form, as well as many specific generators proposed in the literature or found in widely-used software. It provides general implementations of the classical statistical tests for random number generators, as well as several others proposed in the literature, and some original ones. These tests can be applied to the generators predefined in the library and to user-defined generators. Specific tests suites for either sequences of uniform random numbers in [0,1] or bit sequences are also available. Basic tools for plotting vectors of points produced by generators are provided as well. Additional software permits one to perform systematic studies of the interaction between a specific test and the structure of the point sets produced by a given family of random number generators. That is, for a given kind of test and a given class of random number generators, to determine how large should be the sample size of the test, as a function of the generator's period length, before the generator starts to fail the test systematically.

SLOCCount can count physical SLOC for a wide number of languages. It can gracefully handle awkward situations in many languages, for example, it can determine the syntax used in different assembly language files and adjust appropriately, it knows about Python's use of string constants as comments, and it can handle various Perl oddities (e.g., perlpods, here documents, and Perl's __END__ marker). It even has a "generic" SLOC counter that you may be able to use count the SLOC of other languages (depending on the language's syntax). SLOCCount can also take a large list of files and automatically categorize them using a number of different heuristics. The heuristics automatically determine if a file is a source code file or not, and if so, which language it's written in. It will even examine file headers to attempt to accurately determine the file's true type. As a result, you can analyze large systems completely automatically. Finally, SLOCCount has some report-generating tools to collect the data generated, and then present it in several different formats and sorted different ways. The report-generating tool can also generate simple tab- separated files so data can be passed on to other analysis tools (such as spreadsheets and database systems).

LyX is a document processor that encourages an approach to writing based on the structure of your documents (WYSIWYM) and not simply their appearance (WYSIWYG). LyX combines the power and flexibility of TeX/LaTeX with the ease of use of a graphical interface. This results in world-class support for creation of mathematical content (via a fully integrated equation editor) and structured documents like academic articles, theses, and books. In addition, staples of scientific authoring such as reference list and index creation come standard. But you can also use LyX to create a letter or a novel or a theatre play or film script. A broad array of ready, well-designed document layouts are built in. LyX is for people who want their writing to look great, right out of the box. No more endless tinkering with formatting details, "finger painting" font attributes or futzing around with page boundaries. You just write. On screen, LyX looks like any word processor; its printed output - or richly cross-referenced PDF, just as readily produced - looks like nothing else.

Synth is a custom packge repository builder for FreeBSD and DragonFly. It is intended to replace Portmaster, portupgrade, and poudriere for the average user. It is simple to learn (the powerful options are limited in number) and user-friendly, but it is extremely fast due to its parallel building capability. It will "drop-in" on any system as it leverages the stock pkg(8) facilities. All ports are built in a clean environment, so it is finally safe to build ports as needed on a live system. The default profile is the system itself, not a new jail, which can be a valuable feature for some environments. To bring a system up-to-date only requires one command after the ports tree is updated: > synth upgrade-system During the building process, a curses-based display will show the status of all the builders and the entire bulk run process. Synth is intended to be grasped and utilized by novice users within minutes, but offers most of the same powerful features as Poudriere for the power users. Synth requires no preparation; it works immediately upon installation.

Tinderbox is a package building system for FreeBSD ports, based on official Portbuild scripts used on pointyhat building cluster. Tinderbox was written by Joe Marcus Clarke. You can define multiple jails (base system versions) and multiple portstrees. The combination of jail and portstree is called a build. A Tinderbox jail is not what is understood as a jail in FreeBSD, it is in fact a given world in a chroot. Tinderbox supports automatic tracking of dependencies and only rebuilds packages that changed since last run. Tinderbox has support for email notification of failed builds. Tinderbox also integrates well with ccache. Tinderbox is designed to easily provide package sets of ports you need, for platforms and architectures you need. Tinderbox is also excellent tool for testing new ports and port upgrades, especially for testing dependencies and packing lists. It's also useful for testing ports on various releases of FreeBSD, since you can run FreeBSD 6.X world as a jail on FreeBSD 7.X/8.X host.

Kerberos V5 is an authentication system developed at MIT. Abridged from the User Guide: Under Kerberos, a client sends a request for a ticket to the Key Distribution Center (KDC). The KDC creates a ticket-granting ticket (TGT) for the client, encrypts it using the client's password as the key, and sends the encrypted TGT back to the client. The client then attempts to decrypt the TGT, using its password. If the client successfully decrypts the TGT, it keeps the decrypted TGT, which indicates proof of the client's identity. The TGT permits the client to obtain additional tickets, which give permission for specific services. Since Kerberos negotiates authenticated, and optionally encrypted, communications between two points anywhere on the internet, it provides a layer of security that is not dependent on which side of a firewall either client is on. The Kerberos V5 package is designed to be easy to use. Most of the commands are nearly identical to UNIX network programs you are already used to. Kerberos V5 is a single-sign-on system, which means that you have to type your password only once per session, and Kerberos does the authenticating and encrypting transparently.

ccrypt is a utility for encrypting and decrypting files and streams. It was designed to replace the standard Unix crypt utility, which is notorious for using a very weak encryption algorithm. ccrypt is based on the Rijndael cipher, which is the U.S. government's chosen candidate for the Advanced Encryption Standard (AES, see http://www.nist.gov/aes/). This cipher is believed to provide very strong security. Unlike Unix crypt, the algorithm provided by ccrypt is not symmetric, i.e., one must specify whether to encrypt or decrypt. The most common way to invoke ccrypt is via the commands ccencrypt and ccdecrypt. There is also a ccat command for decrypting a file directly to the terminal, thus reducing the likelihood of leaving temporary plaintext files around. In addition, there is a compatibility mode for decrypting legacy Unix crypt files. Encryption and decryption depends on a keyword (or key phrase) supplied by the user. By default, the user is prompted to enter a keyword from the terminal. Keywords can consist of any number of characters, and all characters are significant (although ccrypt internally hashes the key to 256 bits). Longer keywords provide better security than short ones, since they are less likely to be discovered by exhaustive search.
