ttmap passively analyzes values of TCP Timestamps in captured IP packets. After collecting enough data, it computes characteristic remote machine parameters. These values let it guess remote operating systems and identify unique machines behind a single IP address. For example, it can analyze remote IP load-balanced clusters.
ttyload is a tty-based utility for monitoring the load averages on a Unix system. It presents 3 graphs, one for each of the 3 common load average numbers (1min, 5min, 15min) that things like uptime normally show you. Each graph is in its own color, and if two or more of the graphs happen to intersect, then the color changes to reflect that.
tub is a user-mode tool to support large dynamic arrays (up to 2.8GB or so) yet still use shared libraries and dynamic linking under Linux on x86. It works around TASK_UNMAPPED_BASE being a system-wide constant instead of an inherited per-process parameter controlled by setrlimit/getrlimit.
TUIpeer works with the TUIAWT Java package, and together they provide a TUI (Text User Interface) look and feel for Java 1.0 and 1.1 applications. In addition, it supports multiple instances of java.awt.Toolkit, a prerequisite for a multi-user JVM. TUIAWT works by sending peer commands and receiving user interface events to and from the remote peer program. Communication with the remote peer program takes place over a socket connection.
tuitest is a tool to create and run automated tests of text user interfaces. It is meant as a complement to the widespread use of unit tests, and uses concepts known from GUI testing tools with the difference that it applies them specifically to text- and terminal-based user interfaces. It consists of a recorder that records the interaction with an application under tests and generates a Ruby script that replays the same interaction, optionally with the same timing. Ruby replaying is supported through a native Ruby module.
