Open Source GSM Network At Dutch Hacker Convention

suntac Re:p2p (141 comments)

Fido-net style....... aha,.... yes we are on the same page again. Had to go back in memory for that one. :-) however yes you could do this. It would mean building a lot of things however nothing is holding you back from building such a thing. You will have to maybe even create your own handsets (or new software for it) however it can be done with enough time (and $). ;-) tell me when you are done :-)

Open Source GSM Network At Dutch Hacker Convention

suntac Re:What are the costs? (141 comments)

Some information is given on the costs during the talk, you can find links to the video archive of the talks at https://wiki.har2009.org/page/Media

some of the pages are currently down I think because the event network is down however servers should be on the move back to the datacenter. Some of the links are currenlty working so you can already have a peak.

Regards,
Johan Louwers.

Johan Louwers writes "Researchers at the University of Rochester have shown that people who played action video games for a few hours a day over the course of a month improved by about 20 percent in their ability to identify letters presented in clutter — a visual acuity test similar to ones used in regular ophthalmology clinics. In essence, playing video game improves your bottom line on a standard eye chart. You can do some of the tests used in the research online."

Johan Louwers writes "Robots will crawl tubes in a short while to investigate power cables running in the tubes to make sure they are still undamaged or in need for a repair. The Robotic Cable Inspection System is developed by Alexander Mamishev a assistant professor of electrical engineering at the University of Washington. Making use infrared thermal analysis and acoustic partial discharge analysis the robot will be checking mile after mile of cable while crawling his way in the tubes."

suntac writes "A collaboration between a mathematician and an artist-geometer has resulted in some of the most mathematically sophisticated and aesthetically gripping animations ever seen in the field. Their visualizations of cutting-edge research in dynamical systems theory not only provide a dramatic new way of visiting mathematical worlds once seen only in the mind's eye, but also point to a new era for the use of computer graphics in communicating and carrying out mathematical research. The two collaborators are Etienne Ghys, a mathematician at the Ecole Normale Suprieure in Lyon, France, and Jos Leys, a Belgian graphic artist and engineer with strong mathematical interests.

suntac writes "Honeywell and the university of Florida are building the fasted space computer ever. According to the press release on the university website the computer will be at least a 100 times faster than any computer in space at the moment. The goal is to have a NASA test mission in 2009 where the computer will be launched into space. Find out more on the university website."

suntac writes "Tony Blair announced today the completion of a British report about global climate chance. The report, created by Nicholas Stern head of the British economics department and former top researcher at the World Bank, indicates that global climate change is at this moment the biggest thread to life on earth. Tony Blair stated that if no action is taken the first symptoms like floods, hunger, and the outburst of malaria would start during this generation. The intention of this report to get more attention to global climate change and to make clear what the results will be when no action is taken. The Cabinet Office launched a website where all the findings can be downloaded. Cabinet Office"

suntac writes ""Scientists at UCL Computer Science have announced funding for an innovative three-year project in January 2007, monitoring the activities of badgers. Although an unlikely subject for computer scientists to be researching, the badger population provides an ideal testing group for a new system of data storage from micro-electro-mechanical systems (MEMS)."

Johan Louwers writes "sciencedaily is reporting on Electronic Chip, Interacting With The Brain, Modifies Pathways For Controlling Movement.

"Researchers at the University of Washington (UW) are working on an implantable electronic chip that may help establish new nerve connections in the part of the brain that controls movement. Their most recent study, to be published in the Nov. 2, 2006, edition of Nature, showed such a device can induce brain changes in monkeys lasting more than a week. Strengthening of weak connections through this mechanism may have potential in the rehabilitation of patients with brain injuries, stroke, or paralysis.""

Johan Louwers writes "The Viking mars mission in 1976 might have missed signs of life due to not completely working analysis equipment. Read the complete article at PNAS:

GC-MS on the Viking 1976 Mars missions did not detect organic molecules on the Martian surface, even those expected from meteorite bombardment. This result suggested that the Martian regolith might hold a potent oxidant that converts all organic molecules to carbon dioxide rapidly relative to the rate at which they arrive. This conclusion is influencing the design of Mars missions. We reexamine this conclusion in light of what is known about the oxidation of organic compounds generally and the nature of organics likely to come to Mars via meteorite.

Johan Louwers writes "New research might reveille the cause of the earthquake that caused the tsunami.
A FULL moon may have triggered the Indian Ocean earthquake that caused the tsunami on 26 December 2004, a new study concludes.

Between October 2004 and August 2005 Robin Crockett from the University of Northampton, UK, and his colleagues monitored tremors and collected tidal data along the Java/Sumatra trench. They found that major quakes were 86 per cent more likely around new and full moons, when tides are at their greatest.

"At new and full moons the biggest mass of water is being loaded and unloaded at the plate boundary," Crockett says. That might be the final push that initiates a quake.

suntac writes "The US could be rife with "internet addicts" who are as clinically ill as alcoholics, according to psychiatrists involved in a nationwide study.

The study, carried out by researchers at Stanford University School of Medicine in California, US, indicates that more than one in eight US residents show signs of "problematic internet use". US internet addicts 'as ill as alcoholics
