Notes: I'm one of the Conectiva (http://www.conectiva.com) founders and was one of the lead developers of Conectiva Linux. I've started doing translations for pt_BR, then worked on the internationalization (i18n) of minicom, net-tools, fetchmail, util-linux, etc, then went to more fun things, developing and maintaining a driver for a X.25 serial sync card (cyclom2x, made by cyclades), maintaining the IPX, LLC and Appletalk network stacks, several nice hacks on the core Linux networking infrastructure and doing random fixes in the Linux Kernel. Now I'm trying to get some time at my home lab to help in other free software projects (kernel janitoring, NetBEUI, 802.11, samba, dietlibc, glibc, etc) to get back to the old, old days of actually having fun coding :-)

Current TODO List:

Move more stuff out of net/ipv[46] to net/core and make more protocols use it.
connection_sock: move connection protocols specific members out of struct sock and into struct connection_sock, see http://master.kernel.org/~acme/sock_class_hierarchy.ps
to see how I want the sock class hierarchy to be. This will save some more bytes in, for example, UDP sockets - MOSTLY DONE
integrate my work on LLC (making it look like TCP), patches for the core are needed before I do this, and patches for glibc getnameinfo/getaddrinfo are in the queue
finish abstracting away access to skb->{data,tail,head,nh,h,mac}
implement DCCP in time to write my paper for this year's (2005) OLS - DONE
hammer wl3501 into shape
kill sk_slab, sk_protinfo, but this has to wait for converting all the network families to use sk_prot, not something to be done in one night 8) - sk_slab was already DONE, sk_protinfo needs a bit more work
make inet_register_protosw or something that replaces it do the protocol slab cache creation, using sk_prot->slab_obj_size - DONE, proto_register takes care of this and more
Once all families are converted to sk->sk_prot, kill struct sock->ops (struct proto_ops) and call sock->sk->sk_prot directly from the syscalls (this idea has to be carefully reviewed)

dwarves on the spotlight

Recently I saw somebody boasting that Linus now uses Fedora and I don’t know why I found it silly. But then when Ingo Molnar even mentioned the name of the package where codiff is available I found that I can be silly too
