Comment Re:Ice...for now. (Score 1) 118

Um, so oil rigs are 0.2 kilometers long and have no width?

And the difference here is impact, very little actually lives IN the ice, so as long as you don't impact the surface or the base of the ice you won't be harming anyone.

Also, if somehow it exploded all we'd get are shards of ice and pools of water not gigantic oil spills...

I'm not saying you're wrong*, just that your arguments are.

*though, incidentally, you are.

Actually, I see it the other way around: you should know how the system is dealing with your data, what it does, when, how often, basically just how the computer processes. if you don't understand that then you're going to end up with unexpected results and bugs.

Learn the base first, then build on that.

ALL programming languages use variables, variables are memory pointers so learning about pointers is going to help you no matter what language you end up with.

MOST programming languages have functions and other re-usable code, the names of these are also pointers and can be handled as such (you can pass a function as the argument to another function (not just the result).

I've never met an object oriented language that didn't follow the same basic construct: data wrapped inside interfaces. I've come across two main types: c++ style and smalltalk style. Most major (widely used) OOP languages follow the c++ style. All use pointers in some way.

Without the knowledge and control of a language with pointers it's the difference between driving a car and using a keyboard to drive a computer game, you're totally disconnected.

I really don't see where the complexity lies with pointers, all named references are pointers, most of them are just automatically dereferenced. It's like a symlink for a bit of memory. If you can't understand that you probably shouldn't be programming.

Also you don't have to stick with C/C++ you just start there.

Just because it's a knee-jerk reaction doesn't mean it's wrong.

Personally I wonder why anyone would start learning real* programming with anything other than C/C++. It's the basis of the majority of the other commonly used languages out there and the majority of the rest have similar syntax and/or keywords. Sort of like learning Latin, the basis of all romance languages, except that the Roman Empire is still around so the language isn't dead.

* I'm not counting the silly qbasic stuff I played with in middle school... and no, I don't consider Visual Basic that much more advanced...

Study Finds Instant Messaging Helps Productivity 149

MojoKid writes "Researchers at Ohio State University and the University of California, Irvine conducted a telephone study by randomly surveying individuals employed full-time who use computers in an office environment at least five hours per week. They netted 912 respondents, of which 29.8 percent claimed to use IM in the workplace 'to keep connected with coworkers and clients.' Neither occupation, education, gender, nor age seem to have an impact on whether an individual is an IM user or not. The study theorizes that using IM enables individuals to 'flag their availability.' Doing so can limit when IM interruptions occur. Even if an IM interruption comes when it is not necessarily convenient to the recipient, it is 'often socially acceptable' to ignore an incoming message or respond with a terse reply stating that the recipient is too busy at the moment to properly respond." Also another study recently found that water is wet, and a third study found that most studies waste money.

Vermont Launches 'Cow Power' System 400

odyaws writes "Central Vermont Public Service has launched Cow Power, a system by which power users can opt to buy 25, 50, or 100% of their electricity from dairy farms that run generators on methane obtained from cow manure. Cow Power costs only 4 cents/kWh more than market price, so a household like mine would only pay $5-6/month more at 100% usage. The big question now is whether Vermont-based Ben & Jerry's Ice Cream will use power generated from the manure of cows treated with Recombinant Bovine Growth Hormone."

A Pacemaker Made From Your Own Cells 54

FiReaNGeL writes to tell us that researchers at the Children's Hospital in Boston are on the road to crafting a pacemaker from living cells instead of an artificial implant. From the article: "When the engineered tissue was implanted into rats, between the right atrium and right ventricle, the implanted cells integrated with the surrounding heart tissue and electrically coupled to neighboring heart cells. Optical mapping of the heart showed that in nearly a third of the hearts, the engineered tissue had established an electrical conduction pathway, which disappeared when the implants were destroyed. The implants remained functional through the animals' lifespan (about 3 years)."

Linux 2.6.17 Released 444

diegocgteleline.es writes "After almost three months, Linux 2.6.17 has been released. The changes include support for Sun Niagara CPUs, a new I/O mechanism called 'splice' which can improve the performance greatly for some applications, a scheduler domain optimized for multicore machines, driver for the widely used broadcom 43xx wifi chip (Apple's Airport Extreme and such), iptables support for the H.323 protocol, CCID2 support for DCCP, softmac layer for the wireless stack, block queue IO tracing, and many other changes listed at the changelog"

Humanity Responsible For Current Climate Change 775

tehanu writes "Scientists working with Antarctic ice have found that the level of greenhouse gases is at the highest level in over half a million years. Carbon dioxide is 27% higher now than any other time over the last 650 000 years. Methane, an even stronger greenhouse gas is 130% higher. The period of time studied covers eight full glacial cycles including a time when the earth's position relative to the sun is the same as it is today. Other scientists have found that the annual rate at which the sea has risen since the industrial revolution is twice that of over the last 5000 years. It is predicted that by 2100 the sea level will be 40cm higher. These results provide strong evidence that human activity since the industrial revolution, rather than just natural processes, has strongly altered the world's climate. As one of the scientists involved in the research put it: 'The levels of primary greenhouse gases such as methane, carbon dioxide and nitrous oxide are up dramatically since the Industrial Revolution, at a speed and magnitude that the Earth has not seen in hundreds of thousands of years.'"
