Comment: online systems to rescue, direct democracy now! (Score 1) 148

Well, that's one idealistic utopias of mine. To have a technology driven dictatorship. We already have the tools. We just need to educate ourselves and our children that representative democracy comes with too much human power, and that brings to surface the worst side of human kind. To exerce power over other humans, to subjugate our own kind in favour of corporations and institutions full of interest for profit, and not to the evolution of mankind. I'm talking about full direct democracy, like Iceland crowdsourcing their constitution and laws, with a online bidding systems like eBay for public civil contracts and development, centralized and unified banking, financial and economic system, ruled and governed by an open-source system, where the taxes fees paid yesterday could be put on projects needed today. We as human beings towards trans-humanist thinking and status-quo need to evolve and embrace such ideals.

+ - Scientists create massively parallel computer from->

MrSeb writes "A group of Japanese scientists have built a massively-parallel, brain-like computer out of an organic molecule called DDQ. This computer, which is built from 300 DDQ “neurons,” has successfully calculated how heat diffuses through a medium, and the mutation of normal cells into cancer cells. The work of Anirban Bandyopadhyay and his team from the National Institute for Materials Science in Tsukuba, Japan, revolves around a molecule called 2,3-dichloro-5,6-dicyano-p-benzoquinone, or DDQ for short. DDQ is a ring molecule that can connect with up to six neighboring DDQ molecules. Most importantly, each DDQ molecule can be programmed into four different states, each conducting electricity differently. 300 DDQ molecules are placed on a gold substrate, and their conductive states and connections to other molecules are programmed using a scanning tunneling microscope. The end result is a cellular automaton of 300 neuron-like molecules that can perform calculations in a massively parallel way. It is another characteristic of DDQ "brains" that is most intriguing: When a DDQ molecule changes state, the change ripples down through the molecules that it's connected to, destroying old bonds and creating new circuits as it goes — much like a neuron making new synapse connections. This could eventually lead to emergent computing, where the DDQ brain can react to external stimuli and evolve over time."

+ - Massively Parallel Computer Built From Single Laye->

Submitted by djeps
djeps (2463954) writes "Japanese scientists have built a cellular automaton from individual molecules that carries out huge numbers of calculations in parallel

Modern computer chips handle data at the mind-blowing rate of some 10^13 bits per second. Neurons, by comparison, fire at a rate of around 100 times per second or so. And yet the brain outperforms the best computers in numerous tasks.

One reason for this is way computations take place. In computers, calculations occur in strict pipelines, one at a time.

In the brain, however, many calculations take place at once. Each neuron communicates with up to 1000 other neurons at any one time. And since the brain consists of billions neurons, the potential for parallel calculating is clearly huge."

+ - Searching for balloons in a social network->

Submitted by djeps
djeps (2463954) writes "The Red Balloon Challenge, sponsored by the Defense Advanced Research Projects Agency (DARPA) of the U.S. Department of Defense, laid out a simple objective: Use social media to identify the GPS coordinates for all 10 balloons, suspended at fixed locations across the country. The first team to do so would win $40,000. The challenge, commemorating the 40th anniversary of the Internet, highlighted social networking’s potential to solve widely distributed, time-sensitive problems."

+ - Making Facebook Self Healing->

Submitted by djeps
djeps (2463954) writes "I've used to achieve this with Nagios Event Handlers scripts and RabbitMQ. But facebook has done it for a far larger scale than my old days of sysadmin: When your infrastructure is the size of Facebook’s, there are always broken servers and pieces of software that have gone down or are generally misbehaving. In most cases, our systems are engineered such that these issues cause little or no impact to people using the site. But sometimes small outages can become bigger outages, causing errors or poor performance on the site. If a piece of broken software or hardware does impact the site, then it's important that we fix it or replace it as quickly as possible. Even if it's not causing issues for users yet, it could in the future so we need to take care of it quickly."
