I built one, tracking fleet vehicles with a custom box, using tiled maps, on behalf of Vodafone, back in 2002.
I still remember I wrote a basic trans-mercator library too!

You are right about this though - it's a moral fashion. Who cares about land size on a map unless you've got the priorities and advancement of a prehistoric king? People with plenty of spare time who constantly talk in an echo chamber[0], that's who.
A bit related - I tried if I can push Fable to write a Garmin map renderer that would be comparably fast (or faster) on Fenix 8 than the one they claim is possible on Fenix 9 only. I think I got very close, rendering detailed topographical vector map at over 15 fps on QEMU simulated single core simple CPU comparable to actual Fenix 8.
Not the IMHO more interesting analog tech which lifts signals out of thermal noise.

That looks interesting, what technology "lifts signals out of thermal noise"?

One of the things I discovered a while back is that even fairly crude trig approximations don't put that much error into your position, over a small enough distance.
To calculate things like straight-line range from where you are now to where you need to put a unit for an emergency, you're probably not working over an area of more than a couple of hundred kilometres radius and the error will be within a few dozen metres. And once you get within about half a k, you're driving towards the column of smoke anyway ;-)

In Y2K I built a Linux on PC104 solution with GPS, bonded dual-channel mobile 9600 baud data links, and a (slow) image feed. It was kind of special to see the data coming over the mobile network in those days: this was before mobile data using basic PSTN modem tech! Very lossy and slow, as the algorithms did not account for mobile voice compression.

Cool software keep it up

The author says:
"It used Voronoi Cells and reduced most math to 8- and 16-bit integer calculations with one or two single-precision floating-point calculations."
I wonder if it can be used to speed up LLM inference.

That's what quantization and stuff is, basically. So yes. Been done for years on all neural net types not just LLMs.

Please can you provide some links to intro level articles?

Of course Mercator projection may go out of fashion soon https://www.independent.co.uk/news/world/africa/world-map-eq... :)
Hope I'm called back to update the library ;)
