Are you inspired with your tub'o'lard? - 22:37
The take away at the Lyneham shops is somewhat (in)famous for a speciality they serve. Deep fried Marsbars! Can you imagine, a marsbar dipped in batter and placed in a boiling tub of lard. I can hear your arteries hardening as I type.

I have however just seen evidence of something even more gastronomically extreme, the Apostropher has an entry mentioning a bar in Georgia that serves two rather inspired dishes: "Hamdog: a hot dog wrapped in a beef patty that's deep fried, covered with chili, cheese and onions, and served on a hoagie bun topped with a fried egg and two fistfuls of fries." and "Luther Burger: a bacon cheeseburger served on a Krispy Kreme doughnut bun.". Personally I wonder if anyone actually eats these dishes and lives for more than another 10 minutes.

The Apostropher does on the whole appear to regularly be quiet amusing (or terrifying depending how you view some of the stories they link). As seen by reading about a Japanese Parent Pining for the Fjords or maybe this Legally blind guy who got a gun licence or a US citizen going for a stroll through Canada in winter. I am beginning to think I had better subscribe to this rss feed.

Never underestimate the bandwidth - 19:40
The title of course comes from the line in Tanenbaum's computer networks book, "Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway."

One of my house mates is running ICQ or similar and it appears to happily use all available bandwidth all the time. This means the latency to Internet sucks for ssh and other interactive stuff. Web browsing even is slowed, and it uses a lot more than half the available bandwidth if I start a large download.

I need to use some form of bandwidth management or queueing on my NAT box, probably something akin to the traffic conditioner mentioned in section 15.8 of the Linux Advanced Routing and Traffic Control HOWTO (which is a little bit out of date now but most of it probably still applies).

I have thought about setting this sort of thing up for a while, so ssh has low latency, however my NAT machine is running an old 2.4 kernel and I do not have the appropriate modules compiled in, the last time I tried a newer kernel out it only got half way through the boot up process. It is time to try another new kernel, this time a 2.6 kernel I reckon, however it will take forever to download 33MB of kernel bzip2 with the current issues on the network. This got me to thinking, it would be faster for me to ride into work, ftp the latest kernel image onto usb memory stick or similar and ride home than it would be for me to download one through the degraded bandwidth into the house.

I would hope I have avoided under estimating the bandwidth of a usb memory stick in a pocket while riding a bike to and from work :)
