Well, I had some time off but I'm back on the Xen port. And it's getting
pretty far. I hit a few weird issues but worked them out. All I have left
to do is get a virtual enet working and I'll be fully booting Plan 9. It's
mostly there.
I'm off for vacation now. At some point in sep. I will be handing the code
out and will probably be looking for some brave souls to help me turn my
code into something worthwhile, as well as find all the things I got
wrong. So, if you think you might want to help, check out the Xen web
page, set it up on your machine, and let me know.
thanks
ron

This "paper" implies feasible attacks against SHA-0:
http://eprint.iacr.org/2004/199.pdf
and there are (unconfirmed) rumors that the attack has been
successfully extended to SHA-1.
I was wondering what the implications of this would be to venti.
It would seem that it may open the door to malicious corruption
of venti data. Of the top of my head -- if you could anticipate
some data that will be stored in the near future and have enough
time to calculate a collision for it, you could submit bogus data
with the same hash. When the data is stored later, it will be
discarded because venti will already think it has the data.
