Comment Another major problem. (Score 1) 130

This is not statistics done on those doing CS degrees, and their employment outcomes.
It's statistics done on linkedin members who have done CS degrees, and their employment outcomes.

Perhaps there is a substantial slice of CS grads who don't do linkedin, and that population is not representative of the sampled one.

It doesn't even need to be very complex or expensive. No need to use vacuum or anything expensive.
Take about 10 meters of 22mm copper pipe.
Coil it into a suitable coil to go round the device.
Paint the inside black.
Wrap the thing in insulation.
Insulate the pipes, and attach to an insulated 55 gallon drum full of tapwater, with a central heating pump.

It will be very, very obvious in the first couple of hours if it's heating at 900, or 3kW.

You've got to read it in context.
Preamble to the constitution:
'We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America.'

This has in many judgements been found to mean it's only effective in the states.

Facebook is not trying to accurately place adverts only to the people who would want to buy the advertised good.

Facebook is trying to sell adverts.

If they can say 'targeted ads have a 30% higher click-rate' - then that may be enough to get people to buy them.
Even if it's off-topic for 95% of the people it's shown to.

For solar concentrated collectors.
These are panels that reflect the magnified image of the sun onto a tiny few centimeter square panel.
These produce absolutely no (well, ~.1% or so) power when there is no direct light, just bright, diffuse light.
Simply because the reflector is reflecting a comparatively dull slice of cloud onto the panel - rather than the bright sun.

Ordinary non-concentrated panels work just fine on diffuse light. (though of course with rather less output due to the lower light level)

Rather depends where you are.
That's about double (on average) the total solar panel output here (UK). (5h/day = 1800kWh/kWp, UK average is around 1K)
An important caveat is that this is entirely useless for places that get a lot of diffuse light.
Concentrated panels work only when you can see the bright disk of the sun - a cloudy bright day produces no power.

Ebola is young in humans. There is no immunity to it like we have some immunity to Flu and various other diseases.
It being young is scary in other ways.
Before now, the virus had about 500 hosts in which to evolve a more spreadable version, and did not.

Even if it mutates to a version that 'only' kills 10% of the population, the truly scary thing is not global Ebola.
In western countries, Ebola in its current form would be a few cases per 'patient zero' coming from outside.

The scary thing is if it evolves, and becomes arielly transmissable.

That way lie hundreds of millions of deaths.
