As a farmer, you can always choose not to use these methods, stay with your traditional way. As you can do in the west also, even in the EU with all its rules and regulations.

And the impact of these grants is overrated. A billion in the whole of Africa is a drop in the ocean. It is more of an experiment really, to see if technology can help, but the problems there are deeply political.

The greek language is not dead, it is still spoken by about 15 mil. people worldwide. "Porfyro" is the deep red color that can be frequently experienced in esp. greek orthodox churches (even in apparell dating many hundreds of years), and "Glauco" is the shiny blue of the aegean sea that made the greek islands famous worldwide.

The words that the greeks used (and still use) have the purpose of describing the natural world, not of scientificaly defining colors according to a theory of vision.

Even the modern theory of color vision acknowledges the principles of color constancy and color adaptation.

Kemalist Turkey was authoritarian from its infancy, with the military establishment in a central political role. Throughout its history, any attempt for liberalization / democratization, respect for human / minority rights etc. was quashed. This domestic and international behavior of Turkey was tolerated by its western allies (namely US and UK) because of its friendly orientation towards these powers. See for example the various coups and juntas, jailing of opposition and journalists, banning of the minority rights (e.g. language) of Kurds, the invasion and continuous occupation of Cyprus, etc.

The unknown factor from a western perspective is how this new Turkey will align itself (or not) with western interests, not a sudden sympathy for fellow Turks.

CRI measures how natural the objects' colors appear under an artificial light source against the objects colors under a natural light source (standardized daylight).

The color temperature and luminosity of natural light sources varies tremendously during the course of the day or in different parts of the world, yet the objects colors remain consistent. This is a property of the human vision called chromatic adaptation. https://en.wikipedia.org/wiki/Chromatic_adaptation

Sources which emit a continuous spectrum have better CRI than tri-color sources, especially on artificially colored objects (dyed/pigmented) due to metamerism. https://en.wikipedia.org/wiki/Metamerism_(color)

Capital controls and all the chaos these entailed were actually imposed before the referendum not after, as suggested in this article. The European Central Bank froze its liquidity support immediately once Tsipras announced the referendum. The Greeks voted NO while they were in the queues for the bank ATMs.

1. In most places it is illegal to provide transport for a fee without a special state-provided license.

2. There are also special legal requirements from the driver, e.g. taxi drivers license.

3. Insurance requirements are different and order of magnitude higher for vehicles that provide such transport.

4. In case of accidents/fatalities or police stops, who bears responsibility/liability? The car owner, the company, the insurer, all of the above? How much danger of arrest/confiscation/huge fines is the driver in? Does lyft indemnify their business partners against such incidents?

5. The drivers earnings should be the least concern for folks who sign up for this scheme

Thanks, it's just brought back memories of IE6 where a website could arbitrarily read user clipboard without notice

So can a website read a users clipboard, and if yes, how can we disable this "feature"?
