Yesterday I took up again and finished (at least for now) the cleanup of netcat. The result is available here. Among other things that I did is IPv6 support and using poll(2) instead of select(2). Note that there is another renewed version of Netcat which is included in OpenBSD. These two are not related; my version does keep most of the original source code (albeit with renamed variables/functions and updated/edited comments -- actually more in spirit than otherwise), while OpenBSD's is said to be a complete rewrite. OpenBSD's version lacks some features (hexdump, line-by-line, multiplexing) but has some more (AF_UNIX sockets and SOCKS support). I hope to get feedback on this.

I made some more patches to Autoconf, all the preliminary plumbing is in place and I'll push more after 2.58 is released.

Done a coupla cool university projects for the Operating Systems course: a kind of UI for the Unix shell written as a Bourne shell script (cool, with dialog -- and made me discover the fabulous shell syntax "${arr[@]}" :->), and a little thingy doing message passing between parent and child processes (I did it with message queues: jeez, what a braindead API, I have 120 lines out of 350 only for the wrappers around them! another mate did it with AF_UNIX sockets which is indeed a lot easier to do and more readable).
