The GPSTk provides both fundamental and advanced GPS processing algorithms. A wide array of functions are provided by the library, notably RINEX I/O, ephemeris calculation, atmospheric refraction models, and positioning algorithms. GPSTk applications provide more concrete benefits to the user, including cycle slip detection and removal, calculation of the Total Electron Content (TEC) of the ionosphere, and RINEX file manipulation.
Ccide reads C, C++, BASIC, or bash source code containing embedded decision tables from stdin, expands the tables, copies the remaining statements, and forms a compilable C or C++ source module, executable bash script, or interpretable BASIC program. Erratic side effects are avoided by evaluating all condition expressions at exactly the same time, and by performing all evaluations and actions in the original sequence.
PDFTextStream is a PDF text and metadata extraction library available for Java and .NET. It supports all versions of the PDF document specification (including v1.7, used by Acrobat 8, 9, and X), extraction of text encoded using double-byte character sets (including Chinese, Japanese, and Korean), decryption of documents encrypted using 40-bit, 128-bit, 256-bit, and variable bit length ciphers, and extraction of all document metadata provided by PDF documents (including form data, bookmarks, and annotations). Easy integration with Jakarta Lucene is included, as well as interactive form update capability.
esniff (formerly dbsniff) is a very basic set of tools useful for network traffic analysis and scripting across machines. It consists of three tools: esniff, nwait/npush, and loss_chk/loss_srv. esniff is a packet sniffer based on pcap that does certain things like traffic summaries (not better but hopefully easier than tcpdump). nwait and npush implement the DOS "pause" command working over the network. loss_chk and loss_srv are for checking the loss rate of a line.
Weplab is a tool to review the security of WEP encryption in wireless networks from an educational point of view. Several attacks are available, so it can measure the effectiveness and minimum requirements of each one. Currently, weplab supports several methods, and it is able to crack the WEP key from 600,000 encrypted packets.
StdioTunnel allows you to tunnel arbitrary TCP connections through any shell access connection. If the connection provides a clear 8-bit data path and allows you to start programs, you can use it with StdioTunnel. It tunnels TCP connections in much the same way SSH does, but is useful in particular cases where SSH port forwarding is disabled, and it does not require running or changing the configuration of any server processes on either side of the connection.
libGlass is a scalable set of components that can be used by applications to perform distributed computing. Applications are built by reusing the available components as needed. One of the major goals of Glass is to be a user-friendly framework, not only suitable for new applications, but also for legacy code. This is an important feature, as most available solutions for distributed computing require a substantial amount of rewrite of legacy code.
