Over 60 power reactors are currently being constructed in 14 countries including China, South Korea and Russia.
Mainland China has 17 nuclear power reactors in operation, 28 under construction, and more about to start construction. Additional reactors are planned, including some of the world's most advanced, to give a five- or six-fold increase in nuclear capacity to at least 58 GWe by 2020, then possibly 200 GWe by 2030, and 400 GWe by 2050.

I see what you mean. To do QoS you need to "un-dumb" the data plane a bit. Perhaps there could be something minimal such as priority queues and bandwidth reservation between ports on a single switch, with the data plane handing bandwidth reservation across multiple switches/routers.
One big problem with SDN APIs including OpenFlow is that they ignore Layer 2 Quality of Service.
For example, there is no way to implement Ethernet Data Center Bridging (DCB) or Audio Video Bridging (AVB) with OpenFlow because there is no feedback about Ethernet frame buffer fullness between the data plane and the control frame.
It would not be rocket science to provide this awareness to the control plane, but I hope someone with the spare time can look into this!
As more time-sensitive flows such as audio and video (and drop-sensitive flows like FCoE) move onto Ethernet and IP, QoS will become more important!
The annual allocation of EB-1 visas is approximately 40,000. In FY 2009, approximately 40 percent of allotted EB-1s went to workers and approximately 60 percent went to spouses and children. EB visas also have a country limit of 7% per country (~2800), so China and India fill these up quickly.
EB1 has not traditionally had a long backlog, but now it does. In FY 2013, there were 48,639 valid EB-1 applications, and the pipeline is getting more full.
In mid April [2012], after a series of high-level meetings, the Japanese government approved the restart of Kansai Electric's Ohi 3 & 4 reactors, and urged the Fukui governor and the Ohi mayor to endorse this decision. They restarted in July. Without the twin 1180 MWe units, significant electricity shortages would have been likely in summer peak periods.
Japan's idled nuclear reactors will gradually be restarted under the newly-elected Prime Minister Shinzo Abe as the units receive the all-clear from the country's Nuclear Regulation Authority, the Nikkei reported.
Japanese LNG prices went up from ~$13/MBTU just before the Fukushima event to ~$18/MBTU in July 2012 (source) just before the 2 reactors restarted, and is at $16.66 today
So as nice as it would be to have more nuclear energy; the window of opportunity is gone.
China has 17 nuclear power reactors in operation, 28 under construction, and more about to start construction.
Chinese nuclear capacity will be 58 GWe by 2020, 200 GWe by 2030, and 400 GWe by 2050.
China has been able to close 71 GWe of small inefficient coal burning power plants since 2006, cutting annual coal consumption by about 82 million tonnes and annual carbon dioxide emissions by some 165 million tonnes.
Nuclear power does not prevent deaths. Not a single one. In fact, it causes quite a few deaths.
Keep in mind that electricity in general saves all kinds of lives. Refrigeration reduces food poisoning deaths, air conditioning reduces heat stroke deaths, electric light reduces deaths from candle burning accidents as well as inhaled particles, electric power runs many life-saving machines in hospitals, dialysis, etc.
I suspect the number of lives saved by any electrical power producing system far outweighs deaths - even coal.
Moving uncompressed HD video (4:2:2 10-bit) requires about 1.5 Gbps, so I am very happy to see the ability to carry 266 professional video streams in one 400 GbE connection in the broadcast plant.
UHDTV1 (sometimes incorrectly called 4K) resolution at 60 fps requires 12 Gbps for 4:2:2 10-bit uncompressed, so it already jumps into 40 GbE connections. I have to admit I am not sure if we will see uncompressed 4K very often even in production, but potentially a visually lossless codec around 1 Gbps would make a lot of sense if it holds up through multiple encode/decode cycles.
I will agree that the US labor force participation rate maxed out in 1999 at 67%, and is now back to 1980 levels at 63.5%. There are lots of issues going on there (including rising college enrollment rates and baby boomers retiring), but you are correct that recent increases in unemployment did not hold back GDP growth much.
It is possible that the newly unemployed contributed so little to GDP that it did not matter much that they were no longer working.
It could have been that there were "efficiencies left on the table" that companies were forced into adopting, and that as these workers come back into the workforce, they will be able to make use of those efficiencies.
Under capitalism, the law of supply and demand will drive the value of labor to zero, as the supply will continue or increase, and the need will drop to negligible amounts.
If the cost of labor is zero, the cost of products will approach zero as well, so everyone can have everything they want for free!
The truth is that in most market situations, increases in worker productivity are reflected in market ages. In the US, total hourly worker compensation has been rising with increased productivity, although we don't see that in wage data because the total compensation increases are going into non-wage/non-taxed benefits such as health insurance.
Moreover in China we see reports like "As rising labor costs push manufacturing of T-shirts, jeans and the like out of China, the country has been able to offset that loss by grabbing the high end."
What happens is exactly what we are starting to see worldwide: Rising unemployment, with jobs liquidating but never returning, and accelerating polarization into the rich and the poor.
From 2009-2013, these charts show unemployment rates (as measured by US standards) dropped in the US, Australia, Canada, Germany, and Japan.
I won't dispute that global income inequality is increasing, but it is increasing because more people are getting rich, not that poor people are becoming poorer.
The number of poor people (living on under $1.25 per day 2005 price level) declined pretty much everywhere from 2005 to 2008. China has taken 660 million people out of poverty since 1981. Even in Africa, from 2005 to 2008, poverty fell by 12 million to 47% - the first time less than half of Africans have been below the poverty line.
There is only a shortage of tech workers willing to work below their market value.
There are plenty of tech workers willing to work below the current first-world market value, but the first world makes that difficult through limiting legal immigration.
Of course this is only a delaying tactic, as foreign countries grow more efficient economies, the protected first world tech workers will find themselves facing competition from non-first world tech companies - and the first world companies will be at a disadvantage because they have a tough time hiring top quality people from other countries.

Who could believe that some well-programmed ideologue might not be able to resist making a completely predictable and entirely redundant post about ideologically anathematised subject X?
Sorry if it is redundant, but sometimes the truth needs to be spelled out several times before needed change occurs.
Despite enormous increases in expenditures, we have not seen significant increases in test scores, etc., over the past 30+ years.
Who could imagine a socialist monopoly would not be able to efficiently deliver the demanded services?
I'm not sure if we are spending too much or too little on education, but I am certain that we are keeping an efficient market in delivering education from forming.

No way, the US only had 33,808 road deaths in 2010.
US road deaths per 100k ppl is 12.3, UK's is 3.59.
US road deaths per 1 billion km is 8.5, UK's is 5.8.
We drive more & farther in the US than the UK, but we're still worse drivers...

Show me a laptop with SCSI, fibre channel or 10GBe please.
Well there if you have Thunderbolt, you can do 10GBASE-T:
ThunderLink NT 1102 (10GBASE-T) 10Gb/s Thunderbolt (2-port) to 10GbE (2-Port).
Because 10GBe doesn't expose PCI to your peripherals
How about ExpEther technology virtualizes PCI Express over Ethernet.

A person who earns $40k a year (a low base for skilled labor) will give roughly $10k a year in taxes...that's a net gain for the government
Actually someone earning $40k is in the middle quintile of incomes, and will generally receive $15k per year in transfer income from the government, so actually they are a net loss for the government.
They might provide a net gain for the private economy of course (or they would likely not have a job).
Most "net gain" for the government comes from upper quintile income individuals.
