The Statistics::LineFit module does weighted or unweighted least-squares line fitting to two-dimensional data (y = a + b * x). (This is also called linear regression.) In addition to the slope and y-intercept, the module can return the square of the correlation coefficient (R squared), the Durbin-Watson statistic, the mean squared error, sigma, the t statistics, the variance of the estimates of the slope and y-intercept, the predicted y values and the residuals of the y values.

DigiTemp is a simple to use console application for reading values from Dallas Semiconductor 1-wire devices. Its main use is for reading temperature sensors, but it also reads counters and understands the 1-wire hubs with devices on different branches of the network. DigiTemp now supports the following 1-wire temperature sensors: DS18S20 (and DS1820), DS18B20, DS1822, the DS2438 Smart Battery Monitor, DS2422 and DS2423 Counters, DS2409 MicroLAN Coupler (used in 1-wire hubs) and the AAG TAI-8540 humidity sensor.

The inplace(1) command is a utility to edit files in-place through given filter commands preserving the original file attributes. Mode and ownership (user and group) are preserved by default, and time (access and modification) by choice. Examples: # Sort files in-place using sort(1): inplace sort file1 file2 file3 # Process image files preserving time and taking backup files: inplace -t -b.orig 'convert -rotate 270 -resize 50%% %1 %2' *.jpg

ike-scan discovers IKE hosts and can also fingerprint them using the retransmission backoff pattern. ike-scan does two things: a) Discovery: Determine which hosts are running IKE. This is done by displaying those hosts which respond to the IKE requests sent by ike-scan. b) Fingerprinting: Determine which IKE implementation the hosts are using. This is done by recording the times of the IKE response packets from the target hosts and comparing the observed retransmission backoff pattern against known patterns.

XAnim is a program that can display animations of various formats on systems running X11. XAnim currently supports the following animation types: + FLI animations. + FLC animations. + IFF animations. The following features are sup- ported: -> Compressions 3,5,7,J(movies) and l(small L). -> Color cycling during single images and anims. -> Display Modes: depth 1-8, EHB, HAM and HAM8. + GIF87a and GIF89a files. -> single and multiple images supported. -> GIF89a animation extensions supported. + GIF89a animation extension support. + a kludgy text file listing gifs and what order to show them in. + DL animations. Formats 1, 2 and partial 3. + Amiga PFX(PageFlipper Plus F/X) animations. TEMP DISABLED + Amiga MovieSetter animations(For those Eric Schwartz fans). + Utah Raster Toolkit RLE images and anims. + AVI animations. Currently supported are -> IBM Ultimotion (ULTI) depth 16. -> JPEG (JPEG) depth 24. images. + MPEG animations. Currently only Type I Frames are displayed. Type B and Type P frames are cur- rently ignored, but will be added in future revs. + WAV audio files may have their sound added to any animation type that doesn't already have audio, by specifying the .wav file after the animation file on the command line. Currently only the PCM audio codec is supported. + any combination of the above on the same command line. XAnim also provides various options that allow the user to alter colormaps, playback speeds, looping modes and can provide on-the-fly scaling of animations with the mouse.

FC++ is a library for functional programming in C++. Functional programming is a programming paradigm in which functions are treated as regular values. Thus, we can have functions that take other functions as parameters. The former functions are called "higher-order" functions. A common feature of functions is that they can be polymorphic. "Polymorphic" means that the same function can be used with arguments of many types. FC++ is distinguished from other libraries (including the C++ Standard Library) by its complete support for polymorphism: FC++ polymorphic higher-order functions can take other polymorphic functions as arguments and return polymorphic functions as results. This is particularly useful (i.e., simplifies code) in C++ where type inference is limited and we often need to pass polymorphic functions around and determine their type later. With FC++ you can define your own higher-order polymorphic functions, but the library also contains a large amount of functionality that can be re-used as-is in C++ programs. This includes infinite ("lazy") lists, useful higher-order functions (like map, compose, etc.), a reference-counting facility that can be used to replace C++ pointers, many common logical and arithmetic operators in a form that can be used with higher-order functions, and more.

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. QEMU has two operating modes: * Full system emulation. In this mode, QEMU emulates a full system (for example a PC), including a processor and various peripherials. It can be used to launch different Operating Systems without rebooting the PC or to debug system code. * User mode emulation (Linux host only). In this mode, QEMU can launch Linux processes compiled for one CPU on another CPU. It can be used to launch the Wine Windows API emulator or to ease cross-compilation and cross-debugging. As QEMU requires no host kernel patches to run, it is very safe and easy to use. This is a slave port of emulators/qemu-sbruno to build only static bsd-user targets named like qemu-mips-static. While still being experimental people have already built quite a few armv6/mips/mips64 packages using these and e.g. poudriere. Some notes are also here: http://wiki.freebsd.org/QemuUserModeHowTo

OpenFst is a library for constructing, combining, optimizing, and searching weighted finite-state transducers (FSTs). Weighted finite-state transducers are automata where each transition has an input label, an output label, and a weight. The more familiar finite-state acceptor is represented as a transducer with each transition's input and output label equal. Finite-state acceptors are used to represent sets of strings (specifically, regular or rational sets); finite-state transducers are used to represent binary relations between pairs of strings (specifically, rational transductions). The weights can be used to represent the cost of taking a particular transition. FSTs have key applications in speech recognition and synthesis, machine translation, optical character recognition, pattern matching, string processing, machine learning, information extraction and retrieval among others. Often a weighted transducer is used to represent a probabilistic model (e.g., an n-gram model, pronunciation model). FSTs can be optimized by determinization and minimization, models can be applied to hypothesis sets (also represented as automata) or cascaded by finite-state composition, and the best results can be selected by shortest-path algorithms.
