Two Moments in Time

Wednesday, August 30th, 2006

Last Monday’s funeral for Te Arikinui Dame Te Atairangikaahu was one of those moments in time that make some of us focus on the passage of something we should have paid more attention to.


The Naming of Tolaga Bay

Sunday, August 27th, 2006

The town of Tolaga Bay on the North Island’s eastern coast, north of Gisborne, is well-known as the home of a marvel of early 20th century engineering – its lengthy wharf.

Tolaga, as it is known to locals, is also unusual in another respect – its name.


Steady Rain Again

Saturday, August 26th, 2006

Steady rain has fallen across the Wellington region since midnight, causing minor disruption.

A few roads have been closed by small landslips, the Johnsonville to Wellington railway line has closed after a passenger unit was derailed by a slip, a water reservoir in the Hutt Valley is being discharged into the Hutt River for fear it will overflow, and the Hutt River has risen due to rainfall and the reservoir spill, causing minor flooding.

Tawa Fire Service has been doing brisk business since about 10 a.m. responding to minor events around the region. Motorists on State Highway 1 face minor delays at Paekakariki due to a partial road blockage caused by the weather.


Success is a Cleft Stick

Wednesday, August 23rd, 2006

Many people presume that a company that has its name enter into common usage would think that it had died and gone to heaven.

To a certain extent this is true, as brand recognition is a key component of advertising and promotional campaigns. However, there is a point at which common use of a company’s name can be come a liability.

Sea-change for Scientists

Sunday, August 20th, 2006

The recent public announcement that Mt Taranaki (Egmont) is expected to erupt within the next 50 years marks a sea-change for New Zealand’s geological scientists.

The announcement was made following a symposium at Massey University in Palmerston North where scientists discussed the effects that such an eruption would have on infrastructure and the economy. Mark Bebbington, of the Institute of Information Sciences and Technology at Massey’s Palmerston North campus, was specific in making the projection based on the volcano’s eruptive history.

Wash Day at Wellington Transmission Centre

Monday, August 14th, 2006

Back in 1981, the Wellington Transmission Centre consisted largely of analogue multiplex equipment, with 4 MHz baseband systems to Auckland, Palmerston North, Nelson, Christchurch and other centres.

The transmission centre was spread across two floors of the central exchange building with telegraph systems on the first floor and the analogue multiplex equipment on the second floor.

This layout proved to be convenient on the day that the cleaners turned up to try to wash the master oscillator.

A Morning for Vivaldi

Friday, August 11th, 2006

I don’t usually write about music on this site, but it seems appropriate on this morning of weak summer sun as we prepare for the opening of the door to an Antarctic blast again this weekend. 😕
