I would hazard a guess you could make 99.5% of transactions with EFTPOS in NZ - the exceptions might be a few vendors at farmers markets (most take EFTPOS), sausage sizzles/ad-hoc fundraisers, fruit honesty boxes on the side of the road, etc. Maybe only 85% would take credit/debit, though.
From my experience in sydney/melbourne more places take credit/debit than NZ but also more places are cash only. Not as much penetration for EFTPOS.
Works for taxis too. An acquaintance of mine has regularly (once or twice a week) had to travel from his home to the airport, about a $100 fare each way. He's used the same taxi driver for about 10 years - knowing that either this driver (or someone the driver vouches for) will be on time every time.
(taxi expenses are covered by his work but personal car travel is not, so he doesn't drive, go figure)
"Normally I'd have copied/moved the files at block-level (eg. using dd or pvmove), but suspecting bad blocks, I went for a file-level copy because then I'd know which files contained the bad blocks."
I believe this tip originated from writers. By leaving your thoughts incomplete, but with an end in mind, you can begin writing the next day and get into the flow immediately.
I get 10-12mbit pretty consistently on unmetered ADSL2, and did at the last two places I lived as well. The couple of people I know with VDSL get 30-40mbit. A couple of others with UFB get the full 100mbit. Perhaps you're just really unlucky. This is all across auckland with telecom, vodafone, slingslot, orcon.
Mobile phones absolutely do interfere with aeroplane systems. You know how your radio goes dit dit-dit dit when you change cell towers or receive a message? Happens with aircraft radios too. Extremely annoying when your passenger ignores your request to turn off their phone. VOR, ADF, NDB and ILS also all use radio waves and could therefore also be subject to interference.
