ytest is a PHPUnit extension, based on the PHP extension "runkit", that allows you to replace static, private, and global functions with fakes, stubs, or mocks. This eases the automated testing of PHP applications that weren't written in a TDD fashion (i.e. test-first). It can also be helpful on projects where many methods are kept private, or projects that don't use OOP so much. ytest has already been used to "test after" (as opposed to "test first") some real-life commercial projects, and has proven useful. It needs PHP >= 5.2.
lsfw (list firewall) helps network administrators deal with firewalling on a huge network. It lists the firewalls rules applied between two points on the network. It uses the configuration of the network equipment and builds a (light) model of the network described by the equipment. This allows probing for access-list matching all over the network, doing routing and firewalling.
LDPC-codes is a collection of programs and modules intended to support research and education concerning Low Density Parity Check (LDPC) codes. The decoding algorithm for LDPC codes is related to that used for Turbo codes, and to probabilistic inference methods used in other fields. Variations on LDPC and Turbo codes are currently the best practical codes known, in terms of their ability to transmit data at rates approaching channel capacity with very low error probability.
NXWidgets is a graphical user interface package for the NuttX RTOS. It integrates seamlessly with the NuttX NX graphics subsystem in order to provide graphic objects, or "widgets". It is written entirely in C++ using only selected "embedded friendly" C++ constructs which are fully supported under NuttX. No additional C++ support libraries are required. It is tailored for use with MCUs in embedded applications. It is ideally suited for the mid-to-upper range of most MCU families. It will work on high-end frame buffer devices as well as on LCDs connected via serial or parallel ports to a small MCU. It will accept position and selection inputs from a mouse or a touchscreen. It will also support character input from a keyboard such as a USB keyboard. It supports a special widget called CKeypad which provides keyboard input via an on-screen keypad which can be operated via a mouse or touchscreen inputs. Some of the graphic objects supported by NXWidgets include labels, buttons, text boxes, button arrays, check boxes, cycle buttons, images, sliders, scrollable list boxes, and progress bars.
statsmodels is a Python package which provides a complement to scipy for statistical computations, including descriptive statistics and estimation of statistical models. The main included model categories are linear, discrete, generalized linear, and robust linear, and, in time series analysis, AR, ARMA, and VAR. It also includes statistical tests mainly for regression diagnostics. statsmodels was renamed from scikits.statsmodels.
