I am never one to fear something new – except perhaps a new release of a JVM.
Some weeks ago, I decided it would be a good idea to upgrade one of my home routers to IOS 15.0(1)M – seeing as I paid enough for a maintenance contract, I’m entitled. Ever since that day, I’ve been unable to ssh to the router with an access-class applied to the VTY lines. Every time, it refuses my connection, but allows it without an access-class.
This morning, I stumbled upon the answer – put ‘vrf-also’ at the end of the access-class line:
access-class 99 in vrf-also. This only matters if you’re running VRF Lite, as I am, because I have a separate firewall and ‘clean’ and ‘dirty’ VRFs.
Never fear something that’s new – expect breakage, and expect to learn.
TfL’s Countdown system for London Buses was a leap forward several years ago. I can now walk up to a bus stop and tell – with reasonable accuracy – how long before my bus arrives.
There is one problem with this – I have to be at the bus stop!
When National Rail introduced Live Departure Boards several years ago, it was a giant leap forward for rail travellers. TfL brought in Live Departure Boards for the Underground some years later, although this is less useful.
Wouldn’t it be absolutely fantastic to have a map of a bus route with the positions of the buses on it? Colour the map in with a deeper shade where the route is more congested, and let people have a visual representation of how long it’s likely to take for their bus to arrive. Before you leave home, have a look to see where the delays are on your route in to work, and re-plan your journey if it’s going to take too long.
I was lucky enough to find out about an event hosted by the GLA – Free London’s Data. This took place nine floors above ground in City Hall with some spectacular views of London. The camera in my HTC Hero isn’t terribly good, and I didn’t bother taking any pictures.
I have several pages of notes and comments which I’ll type up over the next few days.
