Comment Re:Kilocore (Score 1) 136

CMOS technology, is static meaning that there is no current flow through a gate when it is on or off. Current only flows while the transistor is transitioning states.

That's the idea but it has never quite worked that way. There is always a small current flow from vdd to ground even when the gate is "off". At smaller geometries, this leakage becomes not just significant but can be the majority of the power drain. Thus, having lots of cores ready but not active does not help. They still suck power. Finfets help a great deal but only for a while and at 14nm and below the problem is coming back. The work around is to actually turn off the power to inactive regions. This works but shutting down and restarting units is complicated and time consuming, making it more difficult to respond to transient demands.

Comment Re:What is it with Europeans and Bald Eagles? (Score 1) 137

I don't read Dutch, but if you view the linked video, it's clear that whatever kind of eagle they're using, it's not a bald eagle.

I don't read Dutch either but the second eagle is clearly a Bald Eagle. The first eagle (shown in action) appears to be a juvenile Bald Eagle. They don't get the characteristic white heads until maturity.

I don't know why they are using bald eagles either but perhaps it is precisely because they are non-native. The Netherlands probably has laws restricting possession and handling of native raptors, including Golden eagles. These laws might not apply to imports, like the Bald Eagle.

Comment Re:Patents ... (Score 1) 208

Strictly speaking, patents are not a problem for making software open. Open source reveals patented techniques but then, so does the patent application. The competition can see what you are doing but it doesn't matter because they can't use the information.

Which means it is not an excuse for binary blobs. If it source was open, it still would not be free because of the patents but that's another problem.

Binary blobs serve to protect trade secrets including elements are could be but are not yet patented.

The real problem is that hardware development world is insanely protective of IP. So much productivity is lost is due to stifled communication to protect IP that isn't all that unique or useful.

Comment Transitions are allways awkward (Score 5, Insightful) 258

The problem is not that salaries are now open. The problem is that they were secret for so long allowing various forms of corruption to grow and fester. It is always awkward when previously hidden rubbish is exposed to the light. The solution, though, is not to go back to hiding salaries but to keep them open. That way existing inequities get cleaned up and new ones are not allowed to sprout.

They list 10 minutes of Force use by Leia in the 6 movies, perhaps that is what they are referring to?

I was wondering what Force Leia used in those moves, as I don't remember her using the force in a visible way.

Submission + - Study Finds That Attractive Female Students Earn Higher Grades

An anonymous reader writes: writes

Scott Jaschik writes at Inside Higher Education that although most faculty members would deny that physical appearance is a legitimate criterion in grading, a study finds that among similarly qualified female students, those who are physically attractive earn better grades than less attractive female students. For male students, there is no significant relationship between attractiveness and grades. The results hold true whether the faculty member is a man or a woman. The researchers obtained student identification photographs for students at at Metropolitan State University of Denver and had the attractiveness rated, on a scale of 1-10, of all the students. Then they examined 168,092 course grades awarded to the students, using factors such as ACT scores to control for student academic ability. For female students, an increase of one standard deviation in attractiveness was associated with a 0.024 increase in grade (on a 4.0 scale).

The results mirror a similar study that found that those who are attractive in high school are more likely to go on to earn a four-year college degree. Hernandez-Julian says that he found the results of the Metro State study “troubling” and says that there are two possible explanations: “Is it that professors invest more time and energy into the better-looking students, helping them learn more and earn the higher grades? Or do professors simply reward the appearance with higher grades given identical performance? The likely answer, given our growing understanding of the prevalence of implicit biases, is that professors make small adjustments on both of these margins."

Comment Re:There should be some need for new grads (Score 2) 223

Mostly from what I've seen, custom hardware is being replaced by off the shelf components with customizable software.

Yes, I have this trend over the last ten years and accentuated over the last five years.

The 1990's was the golden age of the IC startup. Many many companies were designing their own chips as a result of new tools and the new decoupling of design and manufacturing.

But as we moved through the 2000's, the cost of a developing a new chip rose astronomically. This is due to a combination of the need to make much more complex chips to be competitive and greatly increasing cost to gear up manufacturing at smaller geometries.

Thus chip startups needed a lot more money. This was a hard sell because it became clear in the mid 2000's that overall venture investment in chip startups produced negative returns.

It got worse in more recent times. Quick turn Internet startups could turn an idea into revenue very quickly with small teams and negligible investment in infrastructure. This is very attractive to investors. Why spend tens of millions and wait years for a hardware idea to bring in revenue when software could turn around so much faster and cheaper?

Thus, the way to survive in hardware to do as little hardware as possible (no chips!) and push the secret sauce to software, ideally not even in your device.

Meanwhile, the established companies are no longer pressured by startups to do many new designs. Further they have to front the enormous cost when they do make new chips.

Instead of expansion, we are seeing a wave of consolidation in the chip world.

Comment Aleron Death Star (Score 1) 171

If the GGP can survive the total destruction of Alderon, I think the galactic economy can survive the loss of two Death Stars. Then there is also the clone wars. Frankly, it requires a bit of suspension of disbelief to think that the Galactic economy can function at all since the Galaxy seems to be perpetually at war.

Comment Clearly anti-competive but no regulator concern? (Score 5, Insightful) 56

Once the two are combined, they plan to split into three separate companies, consisting of agricultural chemicals, specialty products and materials, like plastics.
Despite the eventual breakup, the deal would undergo rigorous antitrust scrutiny for all three companies, particularly the agricultural chemicals company. Still, the companies did not expect that the deal would require much in the way of other divestitures to satisfy regulators’ concerns.

So, they plan to combine two competing companies into one and then divide into three non-competing companies and they expect this to satisfy regulators? Are the regulators that corrupt?

That salary might be low in some places and high in others. It might be low in one industry or high in another.


H1-B jobs are supposed to be paid at the prevailing wage for the position and the industry it's in. We can be cynical about how some employers scoff at this and misuse H1-Bs, but the solution is to enforce the existing law, not break it with an unworkable across-the-board salary threshold.

You need both: a requirement to pay at least the prevailing wage and a requirement to pay at least a fixed wage.

Prevailing wage should generally be best but, without a hard number, it is too easy to game. That is what the fixed minimum would come in. No matter how you classify a position to try to work around the prevailing wage requirement, you can't pay less than the fixed minimum.

Comment Wary that it gives congress and excuse to defund (Score 2) 103

Launching to Earth orbit has a clear business plan. Companies with real revenue streams will pay for this service for sound business reasons. Thus, it makes sense for a private company to do this. They can make money this way and that is what all business are out to do.

Going to Mars, though, does not have a clear plan. Where is the profit? Even if you can do it for a reasonable cost, how do you make money? Thus, I'm sure many in NASA and outside, are doubtful that Musk will actually do this.

However, if Elon Musk does send humans to Mars then funding NASA to do the same thing is an expensive redundancy. If enough of Congress believes that story then there will be no funding for NASA.

If Elon Musk does not go to Mars and NASA does not go to Mars (because congress thought Elon Musk would do it) then I guess nobody goes to Mars.

That is the sort wariness I would expect from smart people working at NASA.
