U.S. gas stations under attack by hackers

8542645125_f81a95ee4a_z

Trend Micro researchers Kyle Wilhoit and Stephen Hilt decided to take a closer look at gas station monitoring systems after one was hacked earlier this hear. They set up fake internet-connected systems called “GasPots” — honeypots that mimic the real ones — in several countries to track hackers’ movements.

Innovation is the reason China’s solar is cheap

Solar-Module-Price-1977-2013

You may hear quite often that “the only reason solar is so cheap is because China is dumping cells. ”Let me correct it. Here is the price, as of February 2015, of solar modules, per watt sold in Europe. SE Asia (Malaysia, mostly) is cheapest. China is next. Japan, Korea, and Germany are slightly above that.

Trees improve your health, and researchers develop tool to show exactly where cities should plant them

19767493424_de91d7eef3_z

Pollution levels decrease and the health of people improves when cities plant trees. Studies show that America’s trees save thousands of lives a year, mainly by preventing breathing-related problems (they also make you feel like you have more money, if you’re into that sort of thing).

According scientists at Newcastle University’s Institute for Ageing in the U.K. and Keio University School of Medicine, they say they have cracked the secret of why some people live a healthy and physically independent life over the age of 100: keeping inflammation down and telomeres long.

Not too long from now, entertainment is about to get as real as real life and nothing is ever going to be the same. This is happening thanks to the combination of two forces that you would never expect to overlap. Together, they form a staggeringly potent combination.

Robot warfighters could reduce civilian casualties, calling for a ban now is premature

2879759988_f51b8665d5_z

Ronald C. Arkin:  I’ve been engaged in the debate over autonomous robotic military systems for almost 10 years. I am not averse to a ban, but I’m convinced we should continue researching this technology for the time being. One reason is that I believe such systems might be capable of reducing civilian casualties and property damage when compared to the performance of human warfighters. Thus, it is a contention that calling for an outright ban on this technology is premature, as some groups already are doing.

Comparing brain vs deep learning and the computational complexity of these processes

14599057004_9dc53af6f9_z

Tim Dettmers: In this blog post I will delve into the brain and explain its basic information processing machinery and compare it to deep learning. I do this by moving step-by-step along with the brains electrochemical and biological information processing pipeline and relating it directly to the architecture of convolutional nets. Thereby we will see that a neuron and a convolutional net are very similar information processing machines. While performing this comparison, I will also discuss the computational complexity of these processes and thus derive an estimate for the brains overall computational power. I will use these estimates, along with knowledge from high performance computing, to show that it is unlikely that there will be a technological singularity in this century.

The future of higher education: The #HigherEd #Startup revolution

College-Failure-3

Thomas Frey predicted that 50% of colleges would collapse by 2013. Similarly, Clayton Christiansen is quoted as saying that 50% of colleges will not exist in 15 years. Others have made similar claims. Such predictions are based on tracing the impact and likely trajectory of innovations like blended and online learning, open learning, technologies allowing for mass customization and personalization, adapting learning software, and a growing set of alternative pathways to gainful and skilled employment.
