SolarCalc is a program for estimating the solar radiation and electrical energy yield in a given site around the world. The software has been written in Qt and uses the most recent models of solar radiation conversion by PV effects. The software can take into account many aspects of solar systems such as detailed diffuse/beam correlation models, temperature effects, and shadowing effects. The system allows you to build a user-based archive of components, like solar panels and inverters. Many printing and exporting functions are available, as well as ready-to-use PDF report export.
No-install Unix Tools for Windows is a collection of 18 of the most useful Cygwin tools packaged into a single 1.1MB (floppy sized) EXE file that runs without any installation process. Simply running the executable instantly creates a Unix environment for Windows, without making any persistent changes to the underlying system. It includes bash, less, gzip, grep, find, df, du, ls, cat, cp, mv, ps, rmdir, mkdir, rm, pwd, and tar.
EAsea Specification of Evolutionary Algorithms (EASEA), is a high-level language dedicated to the specification of evolutionary algorithms. The language and compiler are quite mature. EASEA compiles .ez specification files into C++ or Java object files, using existing evolutionary libraries. Supported C++ libraries currently are GALib or EO.
tkbiff allows arbitrary commands to be executed upon mail reception. If you like programs such as xbiff and xbiff++ but wish they were more flexible, then you'll like tkbiff. Unlike other biffs, tkbiff is fully customizable. tkbiff also doesn't waste your valuable screen space with icons; instead, it shows you the mail itself. It supports UNIX, Mac, and Windows, IMAP, POP, and UNIX-style mail files, and SSL and APOP.
The Simple Sockets Library makes sockets easy to use and comes as public domain source code. It resembles C's file I/O, uses whatever port is available, has named servers and port reuse, streaming/blocking sockets used, polling support, blocking/selection support via numerous functions, timeout control and firewall support.
The objective of the NIST Web Metrics Testbed is to explore the feasibility of a range of tools and techniques that support rapid, remote, and automated testing and evaluation of website usability. There are currently six components: 1. Web Static Analyzer Tool (WebSAT): checks web page HTML against typical usability guidelines. 2. Web Category Analysis Tool (WebCAT): lets the usability engineer construct and conduct a web category analysis (card-sorting). 3. Web Variable Instrumenter Program (WebVIP): instruments a website to capture a log of user interaction. 4. Framework for Logging Usability Data (FLUD): a file format and parser for representation of user interaction logs (such as those captured by WebVIP). 5. VisVIP Tool: produces a 3D visualization of user navigation paths through a website, based on FLUD data. 6. TreeDec: adds navigation aids to the pages of a website.
