In case anyone's been wondering at my recent absence, I've been transported across the atlantic ocean and am now furthering my studies at Oxford. After a week and a half of badgering the staff here they've finally laid some Ethernet cable to connect me to the college network, and thereby to the outside world, so I'll be making something of a reappearance now.

I say "something of a reappearance" because I'm theoretically supposed to be working hard on MSc courses and doing research for my qualifying dissertation at the end of the year, so I can't say for certain yet how much time I'll have to spend around here.

Incidentally, my research topic, as accurately as it can be pinned down in one meeting with my supervisor: Distributed supercomputing. (ie, take the ideas behind GIMPS, PiHex, d.net, and SETI@Home, but add some more sophistication in order to make it possible to attack harder problems.)

Nice one. Congrats. How fast is this pipe?

Well... I have 100Mbps ethernet to the 16-port switch on my staircase; that switch has 100Mbps ethernet running to one of two 16-port switches in the college, and then to the router which control the entire college network. From there my packets go over Gbps ethernet directly to the university's main router, which passes them -- I believe over an OC-12 line -- to ja.net, which is the main academic network in the UK.

I'm not sure how much connectivity ja.net has within Europe (although I'd guess quite a bit), but I know that they have 6 transatlantic OC-3 lines going to various north american networks.

In short, I have a great connection, apart from the 200ms of latency.
