yesCoder is a program to hide data in ASCII text files. It can also be used to format ASCII text files. Hiding data means that the data is coded into an ASCII text file. The idea is that this ASCII text file (a poem, a story, technical documentation, etc.) looks so innocent that no one would guess that therein is some interesting data. If you have the need to hide some data like passwords, accounts, phone numbers, etc., so that no one can find it, yesCoder is the right tool for you. You even may send this coded data to other persons via email.
Yessh is a bash program that uses the SSH client. It provides fast connections to Linux/Unix hosts. Just type the name you have chosen for a host, and yessh will connect you via SSH. You don't need to remember the IP address, hostname, login, or password; just one arbitrary name. Accounts with passwords are kept in a secure file where passwords are encrypted using OpenSSL with 128-bit AES. You can use the autoconnect function to connect to your server with 5 keypresses.
Pak transfers multiple, possibly very big, regular files between possibly different hosts you have shell access to. It transmits segment IDs instead of file names and uses on-the-fly Blowfish-CBC encryption while being absolutely restartable with practically no loss of data already transmitted. Encrypted pak streams can be stored in intermediary regular files on untrusted hosts. Several stored pak streams, even truncated ones, can be merged for re-piping without decryption. Integrity is never checked. File offsets of any magnitude are supported via recompilation (the default width is 64 bits). Either UNIX 95 or UNIX 98 conformance is required and sufficient.
yet another yuv viewer (yay) displays 4:2:0, 4:2:2, 4:0:0 YUV, and Y-only pictures and sequences (planar Y:U:V format). It tries to find geometry information such as _widthxheight somewhere in the path and filename (e.g. mobile_352x288.yuv or path/to/yuv/mobile_640x480x400frames/file.yuv).
ypbind-mt is a multi-threaded implementation of a NIS binding daemon. ypbind-mt compiles and works on Linux with glibx 2.x (libc6). It should work on every System with POSIX threads and glibc 2.x. It works under Linux with libc5 and linuxthreads 0.7.1, but this C library isn't really thread safe and shouldn't be used with threads.
yplot is an interface to the PLPlot plotting library written as an extension of yorick. This combination allows one to quickly and easily create high-quality scientific plots from data, even in large structured files. yplot implements 2D line and scatter plots, contour plots, 3D surface, mesh and scatter and line plots. The user is given full control over every aspect of the plot, including symbol types, line types, label placement, fonts, etc. The results can therefore be made suitable for high-quality scientific presentation. A 60 page Postscript tutorial is included with examples and a reference section.
The Network Information Service (NIS) provides a simple network lookup service consisting of databases and processes. It was formerly known as Sun Yellow Pages (YP). The functionality of the two remains the same, only the name has changed. Its purpose is to provide information, that has to be known throughout the network, to all machines on the network.
