Indeed. It is rare to encounter a webgl/gpu visualization that doesn't rev up the fans at 100% while sitting idle, let alone to have this low latency handling input. Virtually all web demos I have seen run terribly because literally 0 attention is paid to actual rendering. The other day somebody submitted one here and admitted they didn't know backface culling was a thing. They also almost universally have no sort of frame pacing.

I find zooming on this world capitals one to be quite slow for some reason, mostly well below 10fps, and it’s rendering all frames rather than skipping to keep up (the wrong decision, I reckon). Panning is excellent; and zooming is fine on /maps/voronoi/, which has only a dozen or so points, which I guess must be few enough not to slow it down. I’m curious what’s going on, but not enough to delve into the code myself.
Actually, even /maps/voronoi/ lags if you zoom in really far, and in a way that can break the scroll capture—I presume the code is non-passively watching scroll events and calling preventDefault(), but once it’s lagging hard enough the browser takes matters into its own hands and says you didn’t act fast enough.

South Africa is split into 4 segments. Johannesburg is not a capital. Otherwise South Africa has 3 capital cities - administrative (Pretoria), legislative (Cape Town) and judicial (Bloemfontein) - but Pretoria is informally considered the "main" capital.
Perhaps you should limit it to capital cities or states with a certain population size. Including all the European microstates does not seem appropriate to me; Andorra, Monaco, San Marino and the Vatican have very varying degrees of independence and geopolitical significance.
zamadatix 2 days ago [-]
Regardless of how one selects states there will always be comments saying it was done wrong. Don't fall into this trap, just stick with one of the UN lists as has already been done here (looks like members+recognized observer states) and accept not everyone can be perfectly pleased with what is considered a state or not.
Interactive data filters would definitely be fun on its own account though. E.g. the population slider or by having a button making it the largest cities above x population instead of countries/capitals or so on with centers of states. It looks like there are several different maps on this site, such things may make it more a single experience with more overall value than the separated parts. Still cool as it is though :) just one possibility to go further with it.

The Vatican is surrounded on all sides by Rome. It is on the boundary of Municipio I (historical center) and Municipio XIII (Aurelia), however. So is Municipio I considered the "actual" capital of Italy?
Also, the Vatican is the Holy See (as in seat), not Holy Sea (as in water)...
jasondavies 2 days ago [-]
Excellent point. I've removed Vatican City from the map for now, as it is entirely enclosed by another capital city (Rome) and so its Voronoi cell will be tiny.

I guess most dutchies would disagree with the decision to pick De Hague as the Main Capital, though :-)
While all power is in De Hague , Amsterdam definitely is the Capital. De Hague is for complaining about, Amsterdam is for celebrating.
jasondavies 2 days ago [-]
Fixed. It was originally Amsterdam, but I was experimenting with resolving ambiguous capitals by using the de facto seat of government, based on other feedback here (e.g. South Africa originally had multiple capitals). I've switched back to the more familiar atlas capital in ambiguous cases.

It would be interesting to see a map which was not minimizing [distance to capital] but instead minimized [distance to capital]/sqrt([national population]). The latter would be more robust against Sybil attacks.
mckn1ght 2 days ago [-]
I was wondering what kind of metric could be used to visualize a nation’s ability to project power. Maybe some ratio involving the furthest distance from the capital city to the nation’s border?
I’m curious why the sqrt of the population in the denominator?
cperciva 2 days ago [-]
Square root of the population is because that's what it takes to normalize large vs small countries. Imagine slicing a country into quarters; each slice has a quarter of the population and half the radius.

I think that's supposed to be read as "or"? (I momentarily had the same confusion myself.)
It took me this map to realize the capital of Sri Lanka is Sri Jayawardenepura Kotte, and not Colombo as I thought for over 30 years.
Always interesting to find capital cities which are in fact not the most famous cities from that country. Makes for great trivia questions.

Not quite - it's somewhat like South Africa in that certain institutions are in Colombo and others in Kotte (specifically the legislature is in Kotte). In addition, Kotte and Colombo are nearly adjacent.

That "non-existent" country between France and Spain would actually be the center of Occitan/Langues d'Oc. (Well, it's actually the location of Andorra)
It is also in the middle of the Pyrenees so of course that is going to push population out to the sides
Same thing for where the areas "bleed over" water regions or some rivers

Suppose right before this re-bordering takes place, the countries are given the chance to change the capitals' location. Suppose further that they all do it to maximize the area after re-bordering.
I wonder how much the result will differ?

I would love to see some stats with this. What countries gain/loss the most? Which countries are the last changed? What areas are the now the most countries away from their original country?
jcranmer 2 days ago [-]
Eyeballing the map:
For largest absolute net gain of land area, I guess Mongolia wins the cake, getting a very large slice of Siberia while losing almost no land. For a percentage net gain of land area, maybe one of the European microstates, or East Timor.
Largest absolute net loss of land area is Russia for sure. Largest percent loss is... probably Russia? Again, losing Siberia is a large fraction of its land, and nobody else seems to be so screwed by the distance.
Excluding overseas territories, there's three borders between Yakutia-cum-Japan and its current capital, Moscow, and another case of that in the far western reaches of Brazil. If you include overseas territories, well, French Polynesia is currently almost literally antipodal from Paris, and I don't really know how you would count 'most countries away' in that case, but you can't really get further than that.

Ukraine's capital is misspelled "Kiev". Should be "Kyiv"
falcor84 2 days ago [-]
Just for a bit of context, this site is from over a decade ago, at which point almost everyone outside of Ukraine used the old spelling of Kiev, despite the official transliteration change to Kyiv from 1995 [0]. Ukraine ended up having to run the KyivNotKiev [1] campaign to get other countries to adopt the new spelling, which mostly gradually happened over the last few years. But I think it's a bit much to expect every resource out there to retroactively update their spelling.
It was always Kyiv. Your (personal or collective) ignorance and/or obsession over moscowite imperiealists doesn't change the name of my city.
