TfL tracking the WiFi MAC addresses of devices moving through the tube network. Enables them to generate quite fine movement maps - down to the level of how people move through large stations.
The Oyster ticketing data only gives entry-exit points - by tracking people's devices as they move through the network they get route information, not just the end points they get from Oyster.
It's both creepy and extremely useful.

New South Wales coastline.
Near 'Mungo Brush' camping area. The inland like is the Bombah Broadwater where I had just been out in my boat.

The Google Panorama stitching has problems with seascapes. I've noticed it nearly consistently messes up sea horisons.

We had this visitor to our holiday house this afternoon. Jenny saw it walk past the door to the balcony. It soon jumped back down into the garden. Last seen disappearing into a neighbors yard.

It's a 'Lace monitor' or Goanna. Big lizards. This specimin was over 1.5m long.

Went north of the harbour yesterday - on a fine Sydney summer's day. Not too hot. Not too cold.

Victims of a thunderstorm that hit my place on Monday the 5th of December in the early evening. I saw the flash though our front door - the strike was on the 11kv line over the road.

The tally in dead equipment - one ageing Motorola SB5101 cable modem - along with the Ethernet interface on the Cisco 2600 that was connected to it. The other victim was the Cable Access Unit that provides the phone service.
The CAU board looks brand new despite being on the outside of my house for over 15 years. Motorola built the CAUs well. The seals were still intact after all those years exposed to the weather.
Optus haven't deployed the Motorola CAUs for years, but are not actively removing them. Fortunately the tech who came out had a CAU removed from some one else's property in his van and the swap was simple.
(The current telephony solution is combined cable modem/IP phone box. They have a reputation for being no where near as robust as the old Motorola gear)

Lyttelton Harbour. The basin is the caldera of a massive volcano. I was assured it was extinct, not dormant, although I have not looked this up.

The highest point on the Isle of Man. You can see England, Scotland, and Ireland from here.
Access only on foot or via the SMR, a tram line that uses a 3rd rail for extra downhill brakes.
