Whataboutism at its finest!

It's not like the US has ever been attacked by other countries or their agents, right?

"Thousands of years"?
Ruzzia isn't much older than the USA.

Stop your moaning. The world is an exciting place to live right now. Get out there and live it.

You are an actual ignorant twat by choice, the worst kind of person on the planet.

Your bubble of bullshit has cut off everything to your brain but air and that is really a shame. Just get out and actually open your little piggy eyes and get away from the FSB narratives. What is with you stupid conspiracy theorists?

On the bright side, those insurrectionists will never read this article.

They will still gather together dressed head to toe in 2nd hand camo in a tight clump in the middle of the city square.
This, they believe, is the correct use of camouflage. Stand out from a crowd and look frightening!

They will have a very short, but very exciting, revolution.

Fake story planted at Reuters today.

Who would think that an organisation that can plant a spy at the head of the NRA can plant a story at Reuters?
The journalist they used is shit-bag anti-west, anti-USA money grubber.

FSB standard tactic.

Gonna be lots of posts by the IRA troll-bot army today.

It's not about the height or otherwise it would be built on a mountain.

There are more factors in play:

Wind velocity and reliability are more predictable over the ocean where there the "friction layer" is less in play and doesn't extend to the same height as over land. Nominally the layer is universally accepted as extending to 2000 feet above land (in reality it varies enormously between say forest and deserts).

The main advantage of long blades is the efficiency that arises from the massive increase in volume of moving air harvested.
Air moving through the circular blade sweep can be thought of as the volume of a cylinder over any measured time interval.
Pi*r ^2H gives the volume of that cylinder. It's the radius squared that matters. The rest are constants in any sample set. If the blade length (r) of 2 units is compared to one of 4 units then the harvested energy is from 4 volumes vs 16 volumes.

TLDR: Long blades give gigantic increases in efficiency but they're a bitch to make, attach to turbines and then to survive in the real world. (Also they apparently rate in energy production dick-measuring competitions. This may be more important to some investors.)

Well to be fair, after the US blows your embassy in Serbia to shit because you had a few parts of a Nighthawk in the cellar, it probably cools the ardour for adventure.
It's not like they wouldn't be able to get anything they want from other sources anyway.

Don't forget the Russians license the tech for the B model. They probably know a few things about it.

The "heat" leaves the planet constantly as radiated energy. The radiated energy that heats the planet is all, but an infinitesimal amount, arriving constantly from the Sun.

The Earth radiates heat. Look up black body radiation.

The atmosphere reduces the rate at which heat leaves the planet (amongst a few other things). It is a complex picture, but a number of the elements that make up the atmosphere have different effects on the rate of heat dispersion. Water vapour has the greatest effect but it is not alone. Small changes in the amount of other atmospheric elements have the effect of changing the rate of dispersion which is in a rough equilibrium.

An example that is easy to follow is to pick a station in a desert and observe the difference between maximum and minimum temperatures in any 24 hour period. Compare it to a coastal station at roughly the same latitude. The rate differs greatly between the stations.
The atmosphere varies greatly in its composition both horizontally and vertically. Therefore to measure the effect, you have to sample many points simultaneously and then use extrapolation and statistics to get an idea of what is happening globally.

It can be argued that the atmosphere is the greatest part of that which keeps the earth average temperature at approx 15 deg C. By changing the makeup of the atmosphere you can move that average up or down.

Reversing the calculations to predict what will happen at one of the locations that data was sampled from, if the average was to change slightly, is as near as impossible a task as trying to explain facebook to a group of mini-goats gambolling around a peak in the Alps.

The first part is hard enough but the concept of accurate predictions of change is harder. Not impossible to predict more broad effects but not easy.

When Ivan took Kazan he set the stage for permanently removing the terror of the Golden Horde. Relentlessly the Russians pushed eastward destroying the Turkic and Tatar whilst building an empire. Those piles of skulls the Horde left at Kiev to remind the Russians of how nasty they were left a lasting effect.

They didn't want to become an Asian nation but rather control those people and prevent another from forming.

Google and Canonical Bring Flutter Apps To Linux and the Snap Store 22

An anonymous reader writes: Google is partnering with the Ubuntu Desktop team at Canonical to bring Linux support to its open source UI framework Flutter. Today's Linux alpha announcement also means Flutter developers can now deploy their apps to the Snap Store. Flutter group product manager Tim Sneath argues this is a big milestone because UI frameworks rarely become versatile and powerful enough for an operating system to depend on. He pointed to Windows being written in C++ rather than .NET, even for applets like the Calculator. Sneath also believes this shows Canonical is willing to invest in a first-class way to build apps for Linux, making Flutter on Linux an official part of Ubuntu. Additionally, enterprises can feel confident about picking Flutter -- it's more evidence of its longevity and technical excellence, Sneath said.
