httptype reads a list of http hosts and optionally the port number for each of these. It queries each host, displaying the type of HTTP server running on that host, if any. It reads the http_proxy and no_proxy environment variables to determine whether to use a proxy or not. These options may also be specified through the command line.
SigLab is a calculator designed for working on signals. You can use it to load, save, or generate signals, and do various operations on and between signals (addition, log, abs, sin, filtering, convolution, fft, correlation, etc.). Signal parts are constantly displayed. SigLab was designed to be able to handle the results of simulations or measurements. It can handle signals with millions of points, keeping in memory a small piece of each signal. To keep good performance, it caches in memory signal portions. SigLab was specifically designed for Ptolemy users. It will start at the end of a simulation and show all asked signals.
