Submission + - Biomass - A Panacea? (theoildrum.com)

Gooseygoose writes:

Below the fold is the 3rd in a series of posts providing analysis (and follow up) on the difficulties of maintain our current energy paradigm with renewable energy (generally, 'the fake fire brigade'). The main authors are Hannes Kunz, President of Institute for Integrated Economic Research (IIER) and Stephen Balogh, a PhD student at SUNY-ESF and Senior Research Associate at IIER. In this post, the authors show that even if we can double current extraction of biomass, this only represents approximately 6% of total U.S. primary energy consumption, and will likely never be enough to serve as a meaningful stabilizer in future energy systems.


Comment Re:My two cents as a software developer (Score 3, Insightful) 362

nowadays, most of the cost of developing a game is the art. of course, you need programmers and when they screw up, it's usually a bigger problem than a broken texture, but there are tons more artists than coders on the credits in major titles - and that's what you mostly pay for.

your point still stands, though.

Man-In-the-Middle Vulnerability For SSL and TLS 170

imbaczek writes "The SSL 3.0+ and TLS 1.0+ protocols are vulnerable to a set of related attacks which allow a man-in-the-middle (MITM) operating at or below the TCP layer to inject a chosen plaintext prefix into the encrypted data stream, often without detection by either end of the connection. This is possible because an 'authentication gap' exists during the renegotiation process, at which the MitM may splice together disparate TLS connections in a completely standards-compliant way. This represents a serious security defect for many or all protocols which run on top of TLS, including HTTPS."

Submission + - Epic releases free version of Unreal Engine (udk.com)

anomnomnomymous writes: Just a week after Unity announced its engine is now available for free to indie users, Epic Games has revealed a free version of its popular Unreal Engine technology. Called the Unreal Development Kit (UDK), it is a free edition of UE3 that allows community, modder and indie users more access to the engine's features and is available for all. Epic said game developers, students, hobbyists, researchers, creators of 3D visualizations and simulations plus digital filmmakers can all take advantage of the UDK for non-commercial use. The UDK can be downloaded at the UDK site, which also offers detailed product features, technical documentation, commercial licensing terms and support resources.

Submission + - EU Leaders Agree on Internet Access Safeguards (net-security.org)

An anonymous reader writes: A user's Internet access may be restricted, if necessary and proportionate, only after a fair and impartial procedure including the user's right to be heard. Member of the European Parliament (MEPs) and Council representatives agreed in negotiations on Wednesday night on this, the last open issue in the telecoms package.

Submission + - The Ultimate Test of Financial Crash Forecasting (technologyreview.com)

KentuckyFC writes: One of the most extraordinary ideas to come out of econophysics in recent years is that it is possible to identify bubbles in real time and predict when they are about to burst. The idea has been championed by Didier Sornette who runs the Financial Crisis Observatory at the Swiss Federal Institute of Technology in Zurich and who already he has a number of impressive predictions under his belt. Earlier this year, for example, he successfully forecast that the Shanghai Composite Index was about to crash. But many critics say these predictions are of limited value. How do we know that Sornette doesn't make predictions on a regular basis and only publicise the ones that come true? Or perhaps he modifies them as the due date gets closer so that they always seem to be right (as weather forecasters do). It's even possible that his predictions influence the markets: perhaps they trigger crashes. To counter these criticisms, Sornette has designed an experiment--called the Financial Bubble Experiment--to test whether his predictions work. Instead of publishing his forecasts, Sornette intends to seal them in an electronic envelope held by a trusted third party, in this case, the physics arXiv. The arXiv time stamps each prediction so that there is no dispute over when it was made and ensures that it cannot be changed. Every six months, Sornette will open the envelopes and publish his predictions so that everyone can see how successful he has been. He posted the first three sealed predictions yesterday and intends to make them public on 1 May 2010.

Submission + - Success in 'space elevator' competition (denverpost.com)

reifman writes: LaserMotive's robot powered by a ground-based laser beam climbed a long cable dangling from a helicopter on Wednesday to qualify for prize money in a $2 million competition to test the potential reality of the science fiction concept of space elevators. Earlier out on the lakebed, team member Nick Burrows had pointed out how it grips the cable with modified skateboard wheels and the laser is aimed with an X Box game controller.
