This is software from a research project. I have led the design
and architecture activities but most of the code was written by Richard Smith.

So ... working on various projects, the majority of the code I have
written has been closely tied to particular pieces of larger
software. However, below there are a very few (sic) that I have
actually managed to extract into self-contained packages.
The software below is not supported - it is all provided "as
is". Generally, it is not maintained. If you find it useful
please let me know ... if you find any bugs please let me know (no
promises to fix, mind!) ... if you use any of this stuff please leave
in an ACK ...

This is a slightly modified version of fping v2.4b2-to-ipv6.
I have added a '-T' flag to allow microsecond timestamps for each ping.
I have tried contacting the maintainer (twice) to have the patch put into
the main release but have recieved no response ... so here it is!
The man page for fping is here.

This Java package allows you to make (canonical) network-order
byte encodings for char, short, int, long, float and double. I created it
for some students so they could build arbitary protocol packets with
Java. It was written for JDK 1.4.1 but I suspect it will work with
later JDKs.
An example program showing how to use it is
here.
Online documentation is here.

This is my (very old but quite fast) software implementation of
the Data Encryption Standard (DES). This uses a standard 56-bit key
(i.e. 64 bits which includes 8 parity bits). However, before you use DES,
read this.
qfDES is used in the UCL multimedia
tools, was previously used in the Open Mash tools
and the UCL OSIMIS platform (which has now been retired!).
The man page for the qfDES API is here.

Some code to help with debugging, including
hexdumpers, loggers, tracers and error printers. The logging code
has separate C and C++ implementations. No documentation ... but it
is reasonably easy to use.

And finally, for an example of well-structured,
self-documenting, code ... see if you can guess what it does before
you run it! It was one of the winning entries in the 5th International Obfuscated C Code Contest in 1988 It was written by Ian Phillips who worked at Cambridge Consultants at the time.
