The rats were trained to respond to either Dutch or Japanese using food as a reward.

Then they were separated into four groups -- one that heard each language spoken by a native, one that heard synthesized speech, one that heard sentences read in either language by different speakers and a fourth that heard the languages played backwards.

Rats rewarded for responding to Japanese did not respond to Dutch and rats trained to recognize Dutch did not respond the spoken Japanese.

The rats could not tell apart Japanese or Dutch played backwards.

OzymanDNS - Advanced exploration into the use of DNS as a general purpose communication medium. DNS is more hostile to this than any other protocol, so the solutions being built should be generalizable.

presenters Dan Kaminsky

history The first version of OzymanDNS was presented at Defcon, where I demonstrated SSH over DNS (and with that, general purpose VPN'ing using the dynamic forwarding discussed at Codecon in 2003) and live streaming radio over DNS. I also discussed in some depth the potential for bypassing firewalls using the proxying components of the protocol. demo "DNS is a routing, caching, globally deployed overlay network on top of the Internet. Last year's Black Ops of DNS discussed rudimentary mechanisms for manipulating that network to achieve low bandwidth but insidiously firewall-penetrating connectivity anywhere and everywhere. This year, we expand this research to show how extensive, bandwidth amplifying routes can be deployed across the two million DNS servers out there -- and demonstrate an aggressively loss tolerant protocol that can extract high speed connectivity from what's usually considered to be the lowest capacity protocol on the Internet." In other words, I'm trying for Video over DNS. I'll also probably demonstrate in greater depth my DNS-based solution to RSS overload.

future plans Once the DNS infrastructure is ready for demo, backport it to general purpose UDP, document the spec, and turn it into a NAT2NAT framework. The lack of a really good solution for this has been a thorn in all of our sides, and the TCP stuntage from years back turned out not to actually be deployable like this would be.

Anyone who has been a regular reader of the Gazette will know that I do occasionally mention my work life, although it accounts for a fraction of my written output. Like many folk I am not always happy at work (I have good days too, I don’t go in miserable all the time as I’m sure former colleagues would attest if they could) and me being me when I mention bad days or annoying occurrences I do so in my own satirical, sarcastic, comedic style. I often put many things into a basic narrative form, add characters etc. So I would coin terms such as ‘Bastardstone’s’ and have a character called ‘Evil Boss’ (my equivalent to Dilbert’s Pointy Haired Boss – in fact I compared head office directives to being in a Dilbert cartoon). I once referred to a chum and former colleague, Olly, when he found a full time IT job after his graduation as being a successful member of the Escape Committee at work. This was brought up at my hearing yesterday. My protest that this was (to me a bloody obvious) spoof on the Great Escape didn’t seem to cut any ice. This will give you an idea of what I faced.
