Multi Threaded TCP Port Scanner allows you to scan 65535 TCP ports on an IP address. You can specify how many threads to run and the timeout. Furthermore, it will tell you the MAC address of the target and the services that are running. You can scan IP addresses on your network and find out which open ports you have.
DynaBlast is a fast Apache HTTPD access_log scanner. It can find hosts that exceed a given number of hits in a given time period, printing them to standard output. It has a "fast mode" that can skip lines that have already been parsed. Multiple dynablast instances are avoided by using a lock file. This make it suitable for crontab usage. It can be run by any user, not just root. It can run in parallel, for example, when analyzing different access_log files. It keeps memory consumption down to about 10 kb, by parsing the access_log file one line at a time.
FormReturn is OMR (Optical Mark Recognition) software that has many features and is easy to use. It gives anyone the ability to design printable forms and distribute, capture, and automatically grade/analyze handwritten multiple choice response information instantly. All you need is the FormReturn Application, a printer, and a document scanner, and you can process hundreds of forms within minutes.
Signsrch is a tool that searches for signatures inside raw files and executables. It can recognize a large number of compression, multimedia, and encryption algorithms and many other things like known strings and portions of anti-debugging code. Definitions can be manually added, since they are based on an ease-to-modify text signature file that is read at runtime. It also supports the scanning of processes, conversion of executable memory offsets, 8, 16, 32 and 64 bits, float and double, plus automatic CRC table creation and C style strings.
Optar is a software codec that generates 2D bar codes for data storage on paper using a black and white laser printer and scanner. It fits 200kB on an A4 page, uses Golay forward error correction codes to ensure reliability, and can also be used to store data on photographic film.
