Bill Gates: Piketty's Attack on Income Inequality Is Right

Luminary Crush Lost in importance is his comment about automation (839 comments)

With robotics becoming more capable all the time even more skilled labor jobs will go away. A prediction is that one in three jobs will be gone by 2025 http://www.computerworld.com/article/2691607/one-in-three-jobs-will-be-taken-by-software-or-robots-by-2025.html and that trend is still ramping up.

What labor-intense industry will technology create? The current arc of innovation is not like that which enabled the move from rural farming to factory farming and sent workers to urban factories and then to work at Starbucks and Wal-Mart.

We'd better get used to a whole lot more socialism, or a whole lot fewer hours worked per week, or some other way to define value for compensation. The current winner-takes-almost-all system will collapse with no employment for the vast majority of humanity.

Bill Gates: Piketty's Attack on Income Inequality Is Right

Luminary Crush Re:Let me get this right (839 comments)

The biggest GDP expansion in this country was when incomes were extremely progressively taxed - up to 90%. It didn't slow down the "American Dream" - such as it was.

In fact, I think highly progressive income taxes make room for more success stories rather than a few very large economic players who can crowd out others. Honestly, there are tens of thousands of individuals who would make excellent CEOs who are never going to get the opportunity. If a CEO hits the 90% bracket and is 'discouraged from creating more value' then step away and make room.

Elon Musk: We Must Put a Million People On Mars To Safeguard Humanity

Luminary Crush Mars has no magnetosphere (549 comments)

While I fully agree we could make this place a Star Trek-like utopian society (a la The Economics of Star Trek), the point is that no matter how seaworthy you make a ship, it can still be sunk. The Earth could still suffer an extinction event that we can't prevent. Mars is really our best Plan B. We have to get in more boats to make sure we stay afloat as a species.

Mars is the easiest of the options. The others - the moon (too little gravity, can never be terraformed), a giant space station (extremely large structure required to contain 1 million humans), Venus (cloud cities perhaps), Jovian satellites (radiation, extreme cold) are tougher options.

Exomoon Detection Technique Could Greatly Expand Potential Habitable Systems

Luminary Crush Re:Intense radiation bands (66 comments)

Tidal effects are relative to the nearness of the orbit. Such a grandoise statement is not accurate.

Exomoon Detection Technique Could Greatly Expand Potential Habitable Systems

Luminary Crush Re:Intense radiation bands (66 comments)

From TFA:

Io’s ionosphere interacts with Jupiter’s magnetosphere, a layer of charged plasma that protects the planet from radiation, to create a frictional current that causes radio wave emissions.

Much like our magnetosphere on Earth protects us from radiation so too can that of a moon with an atmosphere and molten core. Mars doesn't have one and thus is hard-hit by solar radiation.

Your statement is accurate if you are talking about Earth's moon, but not correct in other cases.

Long-Lost Continent Found Under the Indian Ocean

Luminary Crush Re:Very confusing (168 comments)

http://www.bbc.co.uk/news/science-environment-21551149

Researchers have found evidence for a landmass that would have existed between 2,000 and 85 million years ago.

This potentially places the landmass above sea level during a time when humanity could have been present on it.

Meet "Ophelia," Dell's Plan To Reinvent Itself

Luminary Crush I'm not sure how much of a game-changer this is (280 comments)

It's from Wyse, so it's basically a "thin client". Don't get me wrong, Wyse makes good thin clients, but it's not fundamentally different than anything out there already. It's basically a way to run "VDI" (Virtual Desktop Interface) from your pocket.

OK, cool enough, but I can already do that with an app on my smart phone. I can run a plethora of thin client software - Citrix, VMware, Webex, PCAnywhere, Microsoft RDP, VNC... what else? The only unique thing I see here is that you can attach to a larger external screen. With an iPhone you can do that via an Apple TV with mirroring. The experience isn't fantastic but it's only a matter of time for that architecture to improve (same with Android equivalents).

I do not see myself carrying yet another device. I could see myself using my phone this way if the external graphics worked better - and there is nothing technically stopping that from happening now.

Apple or Google/Android could blink and destroy the market for this device.

Navy To Auction Stealth Ship

Luminary Crush Inside the floating dock with the Sea Shadow (124 comments)

Pretty cool. The ship was locked up though, so I only got to check out the outside. It's bigger than you'd think.

Sea Shadow in the floating dock

From what I understand they tried to find a museum for the ship but there were no takers. The dock was in rusty/poor condition, but the ship looked garage-kept ;-)

India Turns Down American Fighter Jets, Buys From France

Luminary Crush Re:french military victories (600 comments)

This is complete nonsense. There were more Nazi sympathizers in the US than in France at the time. Some of our 'captains of industry' were helping Germany build it's war machine.

When defeat was inevitable some in France looked around themselves - the British had been decimated on land and had retreated to their island. The US was uninterested. On France's borders were fascist Germany, fascist Spain, fascist Italy, aloof Switzerland and occupied territory. It looked as though Britain would fall quickly (few thought they could hold on alone as they did at the time) and that the new world order would be one of fascism or communism. It was a dark day, and in those times some people will choose a dark side versus the unknown.

And then come the opportunists - you have those kind in any country, who will gravitate to the winning side in hopes for gains for themselves.

India Turns Down American Fighter Jets, Buys From France

But, the Maginot Line did work perfectly. The Germans were denied crossing that territory. The contingency of what to do when the Germans drove around it was not addressed sufficiently.

India Turns Down American Fighter Jets, Buys From France

Luminary Crush Re:french military victories (600 comments)

Well...not really. The "Schlieffen Plan" was the move through the Netherlands and Belgian plain, but that was not really what happened in WW2 - it was not the 'second time Germany pulled the same trick'. In WW2 the Germans 'faked' the Schlieffen Plan and lured the French and British into a trap.

The Schlieffen plan *WAS* anticipated by the French and British, and they placed the best of their units along the Belgian border. The Belgians were supposed to have allowed French and British troops to move into Belgium into forward prepared positions, but Belgium decided to declare neutrality until invaded (in some foolish hope that Germany would prefer to pound it's head against the French Maginot Line to the south instead). Silly Belgians.

As soon as Germany invaded Belgium the French troops were allowed to cross the border, but now were not able to reach their designated defensive positions (Germany having gotten a head start) and had to have meeting engagements in the field (losing the defender advantage).

However, THIS was the trick. The main German effort was planned to occur through the forests just to the NORTH of the Maginot Line, but also SOUTH of the more open land considered better suited for the warfare. The French and British thought the Ardennes forest was impassable to tanks, and as such put 2nd class divisions (with very few tanks) and reserve troops guarding it. So, as the British and French raced into Belgium to encounter what they thought was the main German attack (in a Schlieffen Plan replay), the real thrust was happening to the south of them. They were soon caught in a salient - a 'bulge' - and quickly the best Allied units were vulnerable to being cut off.

Despite being warned by their own reconnaissance aircraft and captured plans from a downed German aircraft, they ignored the Ardennes until it was too late. By then the Germans had a solid advance going, which thereafter cut off the Allied troops with amazing speed for the time (eg Blitzkrieg).. then there was Dunkerque and the loss of all the equipment of two major armies. 300,000 troops did manage to escape, including 100,000 French.

Now that the Germans had knocked out the British Army and defeated the best of the French units in the north, they turned south. They met occasional stiff resistance but now they severely outnumbered the French units and the end was only a matter of time.

Contrary to some popular beliefs, the Maginot Line was never breached from the front (once surrounded a few smaller forts were captured) and the French had more tanks with better armor and guns than the Germans did. The defeat was really one of leadership, strategy and tactics.

White House Proposes "Wealthy Tax"

Luminary Crush Re:Cap Gains vs. Income (2115 comments)

So you are saying then that any product who's raw materials have already been taxed and the labor to create the finished product has been taxed shouldn't be taxed? And, the profit made from sale of such widget shouldn't be taxed because it's been taxed earlier in the production chain?

Why PCs Trump iPads For User Innovation

Luminary Crush VMware and Citrix (523 comments)

... and several other vendors deliver desktops and apps to end-user devices remotely and increasingly efficiently. TFA is on the wrong side of history - IT will own and control the apps "locked down" and delivered remotely, device-independently. Administration of the endpoint device is a nightmare, and through VDI and app delivery endpoint management is becoming nearly irrelevant as these technologies improve. In fact, the end point becomes irrelevant - the always-on, use anywhere application service is coming (just don't say "cloud" because I'm tired of hearing it).

All your apps are belong to us.

Europe Plans To Ban Petrol Cars From Cities By 2050

Exactly. This does not mention diesel, pure ethanol, natural gas, hydrogen ICE, or any other kind of ICE besides petrol (gasoline) engines. There are plenty of other fuels you can combust inside a cylinder to move a piston.

Exomoon Detection Technique Greatly Expands List of Potential Habitable Systems

Luminary Crush Luminary Crush writes  |  about 3 months ago

Luminary Crush (109477) writes "Most of the detected exoplanets thus far have been gas giants which aren't great candidates for life as we know it. However, many of those planets are in fact in the star's habitable zone and could have moons with conditions more favorable. Until now, methods to detect the moons of such gas giants have been elusive, but researchers at the University of Texas, Arlington have discovered a way to detect the interaction of a moon's ionosphere with the parent gas giant from studies of Jupiter's moon Io. The search for 'Pandora' has begun."

Fusion power by 2020? Researchers say yes and turn to crowdfunding.

Luminary Crush Luminary Crush writes  |  about 6 months ago

Luminary Crush (109477) writes "To date, the bulk of fusion research has been channelled towards a plasma containment and stabilization method. This is the approach used by ITER's tokamak reactor, the cost of which could exceed US$13.7 billion before it's online in the year 2027 (barring further delays). Researchers at LPP Fusion, in a project partially financed by NASA-JPL, are working in a different direction: focus fusion, which focuses the plasma in a very small area to produce fusion and an ion beam which could then be harnessed to produce electricity. It small enough to fit in a shipping container, can double as a rocket engine, and would cost US$50 million to produce the working 5 MW prototype. To reach the next hurdle and demonstrate feasibility, LPP Fusion has started an Indiegogo campaign to raise $200K."

Spinning solar cells - a new take on photovoltaics

Luminary Crush (109477) writes "Spinning solar cell units created by V3 Solar promise a 20x increase in cell efficiency. All material science and concentrator advances of the last 10 years seem like small refinements in comparison.

Potential "Avatar" Gas Giant Exoplanet Discovered

Luminary Crush Luminary Crush writes  |  about 4 years ago

Luminary Crush writes "A gas giant of approximately 1.5 Mj (Jupiter Mass) was discovered on October 22nd, 2010 around the binary star system HD 176051B. It's not known with certainty which component of the binary system the planet is in orbit around at this point as both stars in HD 176051B are relatively Sol-sized (1.07 and .71 solar masses). Named 176051B b, this new exoplanet orbits within the star system's habitable zone, and if mapped onto our solar system with relative distance from our Sun it would place the large planet between Earth and Mars.
While it's unlikely that such a gas giant could host life as we know it (though it's hypothesized), the location of the big planet opens up the intriguing idea of the realization of some of science fiction's famously habitable moons Pandora and Endor. Look no further than our own solar system to see moons with the potential ingredients for life — just add heat."

Life on Titan?

Luminary Crush Luminary Crush writes  |  more than 4 years ago

Luminary Crush writes "Two new papers based on data from NASA's Cassini spacecraft scrutinize the complex chemical activity on the surface of Saturn's moon Titan. While non-biological chemistry offers one possible explanation, some scientists believe these chemical signatures bolster the argument for a primitive, exotic form of life or precursor to life on Titan's surface."

Nearby "Super Earth" may have atmosphere

Luminary Crush Luminary Crush writes  |  more than 4 years ago

Luminary Crush writes "Astronomers announced that they have discovered a "super-Earth" which seems to have an atmosphere orbiting a red dwarf star 40 light-years from Earth. They found the distant planet with a small fleet of ground-based telescopes no larger than those many amateur astronomers have in their backyards. Although the super-Earth is too hot to sustain life, the discovery shows that current, ground-based technologies are capable of finding almost-Earth-sized planets in warm, life-friendly orbits."

The first manned mission to Mars a one-way trip?

Luminary Crush Luminary Crush writes  |  about 6 years ago

Luminary Crush writes "

The first astronauts sent to Mars should be prepared to spend the rest of their lives there, in the same way that European pioneers headed to America knowing they would not return home, says moonwalker Buzz Aldrin. "[the distance and difficulty is why you should] send people there permanently," Aldrin said. "If we are not willing to do that, then I don't think we should just go once and have the expense of doing that and then stop."

Next step: choosing the family and friendly robot for the trip."

Luminary Crush writes "At Ohio State University, researchers have created a new material that overcomes two of the major obstacles to solar power: it absorbs all the energy contained in sunlight, and generates electrons in a way that makes them easier to capture. Chemists and their colleagues at OSU combined electrically conductive plastic with metals including molybdenum and titanium to create the new hybrid material."
