Well, I'd suggest the right question is, how much does this one benchmark matter? Fast enough isn't necessarily fast enough, as people will come up with more and more powerful applications.

That said, the primary CPU isn't the only thing that governs speed. My understanding (and I could be totally wrong, but here goes) is that there's a separate and very fast GPU. Apple's done a lot of work with Grand Central Dispatch (is that the right technology?) to help developers offload as much as possible to the GPU, so what looks like a 5% gain on the CPU might in the real world be 10 times that in a performance increase. And at least Apple claims that the 6 is 50% faster than the 5s (again, IIRC), so if they're telling something that's approaching a reasonable truth, it's not just based on CPU, but on other metrics as well.

Nearly half of the software developers in the United States do not have a college degree. Many never even graduated from high school.

What? I pored over the article and the US BLS link in it to find the source of these statements. Aside from a pull quote that appears as an image in the article but isn't even in the article itself and is unattributed, could someone find me the source of this statistic?

Because I'm a software developer in the United States with a Masters of Science in Computer Science. All of my coworkers have at least a bachelor's degree in one field or another. And my undergrad very much so started with a sink-or-swim weed out course in Scheme and then another in Java. Yes, they were both easy if you already knew how to code but ... this article almost sounds like it's written by someone with no field experience. Granted that's a low sample set, I'd like to know where the other half of us are. Everyone keep in mind that a Computer Science degree is a relatively new thing and there very well may be elderly coders doing a great job without technically a degree in computer science.

The only way I can see the misconception spreading is that people who use Wix to drag and drop a WYSIWYG site (for you older readers that's like FrontPage meets Geocities) erroneously consider themselves "software developers".

I realize that on Slashdot, where people tend to be highly math-oriented, it's a popular fallacy to believe that a calorie is a calorie is a calorie. However, studies like this one have been coming out for years now showing that that's simply not true.

Amen. As you say, some foods are more difficult for the body to extract calories from. The body will end up extracting (roughly) the same number of calories from foods with the same caloric content, but the rate of extraction differs, and this can make all the difference. That's one of the ideas behind diets like the South Beach diet: it tries to avoid insulin spikes, which helps control hunger, which helps dieters resist over-eating. Insulin spikes cause all sorts of interesting physiological reactions beyond making a person hungry, such as fatigue, and can contribute to the development of diseases such as diabetes. While not the cause of all the world's woes, insulin spikes (and the foods that cause them) are good things to avoid unless, you know, you suddenly need to outrun a bear. If you're being chased by a bear, by all means suck down that energy gel. And don't bother running downhill; that's a myth -- bears can run downhill as fast as they can uphill, and they can run up to 37 miles an hour. So the bear will still get you, but at least after eating the energy gel you'll taste a little sweeter for the bear.

140 calories from a can of coke is not equivalent to, and will not have the same effect on your body, as 150 calories from 1/4 cup of steel-cut oats. Your health will be better for eating the oats. I don't know whether bears prefer coke or oats; they probably prefer coke, but don't quote me on that.

+ - Conservatives Release New Video Proving Global Warming is a Hoax->

Submitted by Anonymous Coward
An anonymous reader writes "Conservative Louisiana House of Representative Lenar Whitney has released a new four minute video on Youtube proving once and for all that global warming is a hoax. In the heavily referenced and peer reviewed video, Whitney puts to rest global warming — something "any ten year-old can invalidate." She points out the important fact that our planet "has done nothing but get colder each year." The highly polished video with special effects clearly exhausted all of Whitney's cognitive powers in researching and backing up each point in her proof that global warming is the "greatest deception in the history of mankind." Fat cat scientists and their propaganda machines don't stand a chance with this hardworking former oilfield equipment company sales employee to set the record straight."

Pros: Today's article has more content than the usual Dice front page linkage. Great article if you're not a programmer but feel stymied by the wide assortment of languages out there. Although instead of hemming and hawing before making your first project you're better off listening to Winston Churchill and sticking your feet in the mud: "The maxim 'Nothing avails but perfection' may be spelt shorter -- 'Paralysis."

Cons: It barely scratches the surface of an incredibly deep topic with unlimited facets. And when one is considering investing potential technical debt into a technology, this probably wouldn't even suffice as an introduction let alone table of contents. Words spent on anecdotes ("In 2004, a coworker of mine referred to it as a 'toy language.'" like, lol no way bro!) could have been better spent on things like Lambdas in Java 8. Most interesting on the list is Erlang? Seems to be more of a random addition that could just as easily been Scala, Ruby, Groovy, Clojure, Dart -- whatever the cool hip thing it is we're playing with today but doesn't seem to quite pan out on a massive scale ...

MIT Combines Carbon Foam and Graphite Flakes For Efficient Solar Steam Generati 110

Posted by timothy
from the science-fiction-future-awaits dept.
rtoz (2530056) writes Researchers at MIT have developed a new spongelike material structure which can use 85% of incoming solar energy for converting water into steam. This spongelike structure has a layer of graphite flakes and an underlying carbon foam. This structure has many small pores. It can float on the water, and it will act as an insulator for preventing heat from escaping to the underlying liquid. As sunlight hits the structure, it creates a hotspot in the graphite layer, generating a pressure gradient that draws water up through the carbon foam. As water seeps into the graphite layer, the heat concentrated in the graphite turns the water into steam. This structure works much like a sponge. It is a significant improvement over recent approaches to solar-powered steam generation. And, this setup loses very little heat in the process, and can produce steam at relatively low solar intensity. If scaled up, this setup will not require complex, costly systems to highly concentrate sunlight.

So a whois.net domain name lookup on their site yielded nothing. And there are suspiciously no patents mentioning "wetag" or "ifind" and the names they listed (Dr. Paul McArthur) are in patents but for cold fusion BS in California.

Surely, though, they must have registered the "iFind" trademark? And if you search on TESS we find:

Owner (APPLICANT) WeTag, Inc. CORPORATION TEXAS 3309 San Mateo Drive Plano TEXAS 75023

With an attorney listed as "Richard G. Eldredge" which corresponds to a local attorney. Before you deploy the door kickers to lynch somebody, that address is just somebody's $200,000 house and could possibly be a random address used by a jerk. Remember that it's entirely possible that this is all a front by some other actor and someone was paid western union/bitcoin to register this trademark through this attorney without realizing they were just being used by literally anyone in the world ... of course, kickstarter should have even better transaction details (hopefully).

I'm over in SE Portland, near Reed, and Verizon's fiber offering may be available on the west side, but it's certainly not available here.

Over here, CenturyLink's 20Mbps DSL offering isn't even available; speeds are 1-1.5 Mbps, tops, with their service. Doesn't stop them from sending me monthly invitations to switch to them and get up to 20Mbps. You'd think that they could integrate their mailer database and their service availability database and only send offers to people who (a) can take advantage of those offers and (b) haven't already told them to F off multiple times.
"Thankfully", there's Comcast. Honestly, Comcast's service is really, really great. It's fast and reliable, and on those rare occasions that I've had to call into their support team, the people on the other side of the call have been awesome. My only complaint about them is that, since they're effectively a monopoly, they are clearly charging WAY more than they could afford to charge and still be very profitable, and certainly well above what the rates would be if there were any real competition. Again, DSL just isn't a competition here.
I've heard that where Google Fiber exists, Comcast's broadband fees are something like half of what they charge here. I can't wait for Google Fiber to come in. I'd switch in a heartbeat, just out of principal.

1. Build an electric car that's heads and shoulders above the competition.
2. Build an innovative charging infrastructure to allow for long distance driving.
3. Open up the technology for that charging infrastructure so that gas stations and the like can start getting in on the action and making some profit.
4. With charging infrastructure becoming ubiquitous, that takes away many people's concerns about buying your car.
5. Also, with charging infrastructure becoming ubiquitous, that may encourage other auto manufacturers to move past compliance cars and actually start selling quality vehicles.
6. Tout competition's success as your own success, as it's built on your platform. Competition isn't only good PR in this context, but it carries with it the subtext that electric cars are a product category that is here to stay.

To some degree, I still like the idea of plug-in hybrids for the time being. But if this "open supercharger" thing is as successful as I think it's going to be, there could be a sea change in the consumer automotive market.

If you think the system is working, ask someone who's waiting for a prompt.
