Comment Infrastructure and competition (Score 1) 119

Weather forecast need an infrastructure of weather stations. Given that they are properties of the weather forecast companies, competition means replicating the same infrastructure, or more likely divide it since there will not be more money flowing to the whole industry to duplicate weather stations.

Competition will therefore not bring a better service here. A solution could be to create a public service for collecting data, and leave competition to interpretation of the data. Or just do not leave that field to competition.

Oral supplementation is quite effective on most people, which just the problem that in order to acheive the same blood levels, some need 1000 UI per day, and others need 10000 UI (a harmful dose for the formers).

The risk/benefit ratio of vitamin D is such that supplementing is a good idea anyway. Taking 1000 UI per day will not harm and it can only help.

But in order to get full benefits, higher doses bases on blood testing are required (because you can get an overdose of vitamin D). Studies finding no benefit tend to use a low dose without checking blood levels

Well, statistics says french workers strikes days are below average EU level. The point is that french workers tend to strike against the government instead of their employer, which produce fewer but bigger and more visible strikes.

Real Programs don't use shared text. Otherwise, how can they use functions for scratch space after they are finished calling them?
