Climate Change Prompts Emperor Penguins To Find New Breeding Grounds 215

An anonymous reader writes Researchers have discovered that emperor penguins may not be faithful to their previous nesting locations, as previously thought. Scientists have long thought that emperor penguins were philopatric, returning to the same location to nest each year. However, a new research study showed that the penguins may be behaving in ways that allow them to adapt to their changing environment. Lead author Michelle LaRue said,"Our research showing that colonies seem to appear and disappear throughout the years challenges behaviors we thought we understood about emperor penguins. If we assume that these birds come back to the same locations every year, without fail, these new colonies we see on satellite images wouldn't make any sense. These birds didn't just appear out of thin air—they had to have come from somewhere else. This suggests that emperor penguins move among colonies. That means we need to revisit how we interpret population changes and the causes of those changes."

In all aspects of education, from primary school to university, the growing swarms of administrators soak up the budget. In some school systems, they vastly outnumber the actual teachers, have better pay, and yet contribute nothing to the operation of the schools.

Don't forget those in the construction industry. Like administrators, they contribute where it counts: in the voting booth where they help elect those that will continue to increase spending on that abstraction "education" rather than on actual educators.

Teaching College Is No Longer a Middle Class Job 538

An anonymous reader writes When you think of people who teach at a college, you probably imagine moderately affluent professors with nice houses and cars. All that tuition has to go into competitive salaries, right? Unfortunately, it seems being a college instructor is becoming less and less lucrative, even to the point of poverty. From the article: "Most university-level instructors are ... contingent employees, working on a contract basis year to year or semester to semester. Some of these contingent employees are full-time lecturers, and many are adjunct instructors: part-time employees, paid per class, often without health insurance or retirement benefits. This is a relatively new phenomenon: in 1969, 78 percent of professors held tenure-track positions. By 2009 this percentage had shrunk to 33.5." This is detrimental to learning as well. Some adjunct faculty, desperate to keep jobs, rely on easy courses and popularity with students to stay employed. Many others feel obligated to help students beyond the limited office hours they're paid for, essentially working for free in order to get the students the help they need. At a time when tuition prices are rising faster than ever, why are we skimping on the most fundamental aspect of college?

There are other advantages to shrinking components. Higher clock rates become possible.

You'd think so, but the problem is global interconnect. Not gates. It was all the way back at the 250nm node when interconnect and gate delay were about the same.

At the 28nm node, wire delay is responsible for something like 80% of the time it takes for signals to work their way through a circuit.

And it some cases inverters are actually used to help signals propagate more quickly down long wires. In other words, long wires are so slow compared to gates that adding gates can speed things up!

according to our social contract

Show me this "social contract". I think a big part of the problem here is delusional reasoning based on imaginary things that don't actually exist. I grant that there is cooperation in a society, it is an inherent and necessary component. But to claim that is a "contract", requires that the thing be voluntary and agreed to.

In any type of reasonable court the "social contract" concept would be thrown out due to Unconscionability. One side has grossly unequal bargaining power. Social Contract is a nicer way of saying "Ultima Ratio".

The flip side of that is that NO western job is worth the prevailing wage, except in ultra competitive fields with international mobility like movie or basketball stars. For all other jobs, cooks, engineers, doctors, street vendors, architects and bankers etc., you will always find some equally qualified individual in some developing country ready to work for (significantly) less.

If skilled workers were paid what their production was actually worth, employers wouldn't profit from the transaction and hiring them would be counterproductive for employers. Employment is an arbitrage game, where employers offer employees some stability in return for being paid less than the actual goods they produce are worth.

The fact that globalization, technology and the liberalization of gender roles has expanded the workforce and thus pushed wages down is predictable. It's somewhat interesting that the fields that still have a large gender gap (Nurses, Computer Programmers) have some of the highest wages...likely because of a lack of supply of workers. Nice to see Google is trying to "fix" that....

I believe many ISPs are actively sabotaging customer's connections to some of the internet's content

They don't have to. The protocols we use are more than capable of screwing with things.

Consider TCP: the protocol is BY DESIGN meant to exponentially increase the amount of data dumped on a link until it overloads and begins dropping packets. TCP then throttles for a little while and then soon goes back to bashing the network with packets until it breaks again.

No, the problem is that the judicial branch told the FCC that *until* they classify ISPs as common carriers, they don't have the authority to mandate anything with regards to paid prioritization or de-prioritization.

With Mr. Wheeler in charge, there doesn't seem to be much impetus to reclassify the ISPs in that way.

I am an independent who often votes republican, and I believe that the republican bill as currently laid out is a bad plan. Internet service is a utility in the 21st century, and should be treated that way.
