HC-SR04 Ultrasonic Arduino Library is specifically for the HC-SR04 ultrasonic sensor. It features timing, metric conversion, and standard deviation methods, plus a few support methods. It is written in C++ to conserve the namespace. The conversion formula can be easily modified to optimize the accuracy of conversion at different distances for inches and centimeters. Multiple buffers of different lengths can be created for determining standard deviation.
mojoPortal is a cross-platform object oriented Web site framework. It supports PostgreSQL, MySQL, Firebird, SQLite and MS SQL for the backend. It includes a content management system, forums, blogs, photo galleries, newsletter, polls, surveys, an event calendar, an RSS feed aggregator, and a skinnable design.
Easy PHP Thumbnail Class can be used to manipulate images and generate thumbnails. It can load images from files and generate thumbnails that can be saved to files or be generated as the current script output. The class can also perform other image manipulation functions such as adding shadows, clipping rounded corners, filters, bilineair image deformations, and more. Over 45 image manipulation functions are available.
SBLIM (pronounced "sublime"), the Standards Based Linux Instrumentation for Manageability is an IBM Open Source project, intended to enhance the manageability of GNU/Linux systems. It does so by enabling GNU/Linux for WBEM, Web Based Enterprise Management, a set of standards defined by the DMTF and fostered by the WBEMsource initiative.
Simple PHP Chat Script is an AJAX chatting system which does not require a database. It works with text files saved on the server, so it is fast and requires very few server resources. It can be included in both PHP or HTML files (in blogs, forums), but the server must run PHP. The script can easily be changed to be used in other languages, just by translating the texts in a single file. It can have one or more chat rooms. The user can add smiles in chat, and can format the text with Bold, Italic, an Underline.
Archive is a fully drag-and-drop multi-format archiver. Drag a directory onto it to create an archive. Drag an archive onto it to extract to a directory. It can also compress and decompress streams (for example, you could drag a .gz file onto Archive and from Archive into your text editor).
Visual Interactive Datapipe (Vida) is an interactive visual datapipe for all *nix systems, which allows socket communications to be redirected over pipes. It features an ncurses interface that allows the creation of multiple datapipes, each supporting multiple connections. It is possible to sniff and log traffic in various ways, hijack piped connections, perform DNS hijacking on switched LANs, and much more.
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.
DAPL (Direct Access Provider Library) is a transport-independent, platform-independent, high-performance API for using the remote direct memory access (RDMA) capabilities of modern interconnect technologies such as InfiniBand, the Virtual Interface Architecture, and iWARP. This is the reference implementation of that specification by the DAT Collaborative who maintain the DAPL API.
