Dragons' Den is the show that Shark Tank is based on. It has run for many seasons in the UK and Canada (and short runs in Australia and Ireland and elsewhere). Episodes can be found on Youtube.

In turn, Dragon's Den was based on a Japanese show (The Tigers of Money).


Various sources for day-length estimates are available, see for example https://design-of-time.com/slowing.htm (appendix A).


The province of Alberta, Canada (more than twice the land area of New Zealand) is free of rats.

In their case, it was largely by stopping rats entering from the east (Saskatchewan) in the 1950's - there are natural barriers on the other three sides.

History: http://www1.agric.gov.ab.ca/$department/deptdocs.nsf/all/agd...

Still, NZ could be divided into areas that have natural barriers, and peninulas (plenty of them), and start intensive poisoning barriers in those areas, expanding towards the sea.

Doesn't need gene editing, which certainly has unknown risks.


Interesting that there are no current transpacific cables at all landing in western Canada. Makes the area very dependent on the neighbour to the south (which is an earthquake risk, as well as a political risk).


There are overland fiber runs. One map is:

Those will connect with arctic and atlantic undersea cables, so Canada wouldn't be completely cut off.


Ehh, I imagine if things get too bad they can always lay a new one. In the meantime Western Canada could probably be connected to Eastern Canada somehow. Given that people were laying tons of cables 120 years ago, it can't be _that_ difficult for a country as big as Canada in crisis.


Canada is well connected internally with Fiber


which is an earthquake risk, as well as a political risk

Oh, come on. Maybe an earthquake risk. But, really, "political risk"? The longest undefended border in the world?


You can drive a further 1200km+ road distance north of Whitehorse, Yukon on the Dempster Highway to Inuvik in the Northwest Territories.

End of the road appears to be just north of town: https://goo.gl/maps/shD9UoxTtK42

Western Canada is big. If you drive from Inuvik to San Diego over 60% of the entire road distance is within Canada.


They're actually building a road north out of Inuvik to Tuktoyaktuk, which will take you to the Arctic Ocean:

I didn't realise that road was so nearly finished. Should be open by end of this year.

That's 3750 km (2400 miles) by road from Vancouver BC to the Arctic Ocean. Longer than Melbourne to Perth across Australia.


That's a beautiful drive. I passed through on my way to Alaska a few years ago. It had some of my favorite stops ever...sometimes just stopping and parking the RV at a pull off even led to gorgeous scenery. One of my favorite hot springs (Liard) is on that route. So many bears and moose and other critters, too.


Unfortunately very few people have their own domain for email (although they should!).

When companies have kindly sent me their entire customer list (by using CC in place of BCC) I see there are very few domains in it outside of the major free email providers, and those that remain are mostly for their work or small business. A personal or family domain is very rare.


I have my own domain, and I really should be using me@myowndomain but I don't. I use gmail. One reason is that so many people and services already know the gmail one so it's hard to change, but the biggest reason is that I don't trust myself nor the place where I registered for my domain to actually maintain the domain name registry and email delivery for say 10 or 20 years without any maintenance. The value of these behemoth services is that they are more or less guaranteed to be more stable than anything you can configure yourself. They are too big to fail. Even just pointing my me@myowndomain to gmail doesn't help here. It just adds a new weakest link to the chain.


I've had domains registered for over 20 years already, much longer than gmail has existed.

You can renew a domain for ten years in advance and easily transfer between registrars (and email providers, I use Fastmail), so it's a lot more reliable for the (very) long term than a third-party service.



An interesting one for London is Train Times vs House Prices [1]. Shows how prices are affected by commute times (and the raw data is downloadable if you want to plot the times on a map).

It was the only number that could not be dialled by accident by letting go of the dial too early. The aim wasn't to dial quickly, it was to avoid accidental calls.

Rotary dials in New Zealand were the other way around (sending ten minus the number dialled pulses) so the emergency number there was (and still is) 111 for the same reason: the hardest to dial by accident.


Rotary phones swirl the opposite direction in the southern hemisphere?


Apparently birds sitting on phone lines could trigger 111.


Yes, in e.g. the UK, perhaps, where 1 was two pulses (although they would be more likely to dial 000, I would think) but not in NZ, for the reason given in the comment you replied to.


Pretty sure 1 is just one pulse in the UK. Zero is at the far end of the dial next to 9.


You're right, it's been a long time since I used a rotary-dial phone (or even a keypad phone that used pulse dialing...) and information like this gets dropped off the stack of 'useful things to know' eventually ;(


Never even thought to ask the question and I live here, you learn something new every day..


In the UK, when I renewed my driving license online I was offered the option to have them pick up the photo from my passport record, rather than send in a new photo.

Since the passport had been issued about 9 years before, the new driving license contained a picture already 9 years old (and identical to the passport).

Nearly ten years later (nearing expiry), it therefore contains a photo about 19 years old. I like to think I still look like that youthful person, of course.
