There are traffic cams in the Netherlands too. But there are only 26 of them and they are much less interesting than the Norwegian traffic cams. But during snowfall they present a nice, gray, flat landscape. At night they present a futuristic cityscape. The cameras are not fixed, so you almost never get the same landscape twice.

We drove approximately 400 km by automobile from Chelyabinsk through Stepnoie to the Arkaim and recorded vegetation structure at random by visual observation along major traffic roads running with automobile approximately 10 km in distance.
The types of vegetation depended mainly on physiognomy with relatively smaller scale approximately some hundreds square meters: Pinus forest, Betula forest, cultivated land and pasture.
Plots along the major roads were randomly selected to cover representative vegetation pattern. Further, around the Arkaim, major vegetation types ware described. Field observations were carried out during early summer season, middle June in 2008.
This theory is contradicted by the 12 hours I spent yesterday watching Russian car dash-cams on YouTube. The russian car inventory must turnover at least every 6 months. Literally and figuratively. (3 stars or bust)
There’s a deeper point here: if your view of Russian life is conditioned by what is available on YouTube, you’e asking for a pretty skewed view of the country. The people who post dash-cam videos are, by definition, those who have cars, dash-cams, and internet connections. Faberge eggs are very pretty, but they say relatively little about per capita wealth in Russia on the eve of the revolution. (Ckb)
As we approached the city, we saw:
- a billboard advertising a concert,
- large signs on top of the buildings near the railway,
- the cathedral on the hill,
- the towers rising from the horizon gleaming in the sun,
- the skyscrapers thrusting, soaring, sitting above the rest,
- a crowd in front of the showroom near the highway,
- more and more people along the way,
- very ominous dark clouds in the sky,
- orchards and orchards,
- the high and snow capped peaks.
She proposes that the brains of all six species have gotten bigger because humans have radically changed the landscape. Where there were once pristine forests and prairies, there are now cities and farms. In this disrupted environment, animals better at learning new things were more likely to survive and have offspring.

So I'm reading this nice book on Bayesian statistics:
It says that a sample of 400 is sufficient in most situations. For the hypergeometric distribution that we draw from this seems to be the case. Going to 1000 samples does not seem to add that much certainty anymore.
