One map to rule them all: UK's Ordnance Survey rolls out its Data Hub and the juicy API goodness that lies therein

Re: Could this become the official UK postcode and address database?

Well certainly three or four years ago there was a very good OS product called AddressBase Plus which was managed by a combination of Royal Mail (for mapping of postcodes and delivery points) and various local authorities. The idea was that it held details of every structure (house, bus stop...) in the UK for use by people like the emergency services.

It's a massive data set, but very high quality.

Back then it didn't have elevation data so to get the heights of things we used to overlay the Environment Agency's LiDAR dat. It would appear that elevation data is now included.

I guess the data used in the AddressBase product is what is used to drive the new API.

Re: So what's the point other that Python & Java suck at calculations?

Ordinary Python does suck at number crunching. That's why we use numpy, so you get the efficiency of C++ with the convenience of Python.

The completely meaningless and cherry-picked example of the 4096x4096 matrix multiplication takes 37s to execute on an single core of an AMD 3900X.

This reminds me of something in ancient history when I was the resident VMS guru somewhereback in the mid 1990s. We suddenly urgently needed some code which used VMS' password system, so I hacked something together in a great rush in C in an hour, with all manner of comments along the lines of "Not production grade code. Do not use this!"

Needless to say it was the one bit of code I wrote for the company which was then reused on every system they shipped thereafter.

Happy days

I worked for Demon managing their broadband products and various weird technologies shortly for a couple of years after they'd been taken over by Thus. Demon were one of the most talented bunch of people I have ever worked with. But the culture clash with Thus was horrendous, and the internal atmosphere, particularly once we'd decamped from Gateway House to Bunhill Row became increasingly awful.

It's a shame that Bill Allen and the rest of the Thus senior management were such utter numpties. I have to wonder what would have happened had they been vaguely competent.

It all seems like a different lifetime, yet it's less than 20 years ago.
