Says [Chief IBM Roadrunner engineer Don] Grice: "A job that would take you about a week to run on Roadrunner would have taken you 20 years to run on a machine just 10 years ago."

Gro'in' pains
Enough 80's references, let's skip to the meat of this post (so to speak). This is from a recent traceroute; DataHop might want to rename one of their nodes to accomodate some expansion in their traffic:

UCT's smallest office
This is one of the candidates, for sure.
And also a candidate for "Least Paperless Office of the Year"
[and I'm tempted to say that it was so small I couldn't fit inside to take pictures, but I was actually too lazy to try]
[office extends from the pillar on the left of the frame to the right of the frame - i.e. 2 window frames]
[the third window frame visible on the right is someone else's office!]
This is in the Leslie Commerce building. At least this is a hard worker (all those papers!), so no comments about the tightwads there, please...

The New Stephenson opus
The new Neal Stephenson book should be out within 6 months!
My guess is it's going to be the most exercises some geeks will get for a while - 928 pages!

Facebook CDN
I don't know how this slipped through the cracks, but I've just noticed that Facebook has started hosting some content on static.ak.fbcdn.net [fbcdn presumably = facebook content distribution network]
Is Facebook planning on using multiple CDNs?
Both static.ak.fbcdn.net and static.ak.facebook.com seem to be hosted by Akamai, so for us "lucky" .ac.za we get routed through IS. This is actually good news, as we have a very high-speed connection to IS from TENET. Unfortunately, most institutions connect slowly into TENET (~30 Mbps for UCT!) and implement some shaping on popular websites. So we don't get most of the benefit.
