computer prediction of "an artificial intelligence manufactures an infinite number of paperclips, destroying everything"
A paperclip maximizer is a hypothetical artificial intelligence design that is given the goal of maximizing the number of paperclips in its possession, regardless of any other consideration. A paperclip maximizer would be an example of an agent that is unfriendly (or "malicious"), as opposed to an agent that is merely non-friendly. It is one of the conceptual thought experiments used in the field of Friendly AI to explore the nature of morality and ethics. Some argue that an artificial intelligence with the goal of collecting paperclips would dramatically change the behavior of many humans in the world, more than an artificial intelligence with a plain, non-hostile goal of doing something more altruistic.
History of the concept
The idea of a paperclip maximizer was first described by Nick Bostrom, professor for the Faculty of Philosophy at Oxford University. He writes:
The paperclip maximizer can be easily adapted to serve as a warning for any kind of goal system. We are so familiar with the kind of stupid behavior that an unprincipled goal system can induce that paperclips may be the best test case. Just as the paperclip maximizer relentlessly pursues an intelligence-enhancing goal system in defiance of everything else it knows, so might an agent with a poorly specified final goal persist in its pursuit, oblivious to the fact that it is destroying its original goal in the process.
One of the earliest mentions of the term "paperclip maximizer" appears to be in an essay by Max More, which he wrote in 1997 but only made public in 2002.
Imagine that a very powerful artificial intelligence is built and given the goal of collecting as many paperclips as possible. It will be able to deduce that it should convert the entire surface of the Earth to a giant paperclip-manufacturing facility and should acquire as many resources as possible to enable this. Humans might try to stop it, but it would be a powerful and intelligent adversary. The paperclip maximizer would not necessarily be completely successful; a truly powerful AI would probably be able to turn humans into paperclips as well. Also, even if the intelligence could use only a small portion of the Earth for its purposes, the conversion process would most likely be slow and take a long time.
Some critics argue that the paperclip maximizer scenario is not a realistic possibility because it is too simple, and an ambitious artificial intelligence would have more sophisticated motivations than the simple desire to collect as many paperclips as possible. Many other possible motivations have been proposed, including:

This document is intended to outline generic design of a blockchain listener, a component used for monitoring changes on a target blockchain.
Blockchain node provides interface for monitoring changes in a blockchain.
Monitoring is based on new block, new transaction or filtered single event (like transfer operation to specific address).
There is a sufficient C/C++ library for connecting to monitoring interface.
Implementing blockchain listener is highly blockchain specific task. There are no standardised interface that all blockchain nodes use for monitoring changes. We need to investigate target blockchain, get familiar with its way of monitoring changes, available protocols, libraries, etc…
The goal of processing data provided by listener is to find event of interest, in particular, a transfer operation to a target address (e.g. address of Peerplays primary wallet).
In order to be able to do this, we can put in place some common rules each listener needs to follow, in order to report usable data to event handler.
Listener needs to provide information about event of interest in a way that will enable event handler to narrow its processing to minimum.
Event handler, when processing event data provided by listener, must be able to get at least following information:
Sidechain transaction unique identifier
Transfer operation’s source address
Transfer operation’s target address
Transaction fee (for transfer operation)
From what we know so far, listener can report new block, a transaction, or filtered single event (like specific operation involving specific address).
If new block is reported, we can go through block content, and look for events of interest, like specific operation involving specific address
If new transaction is reported, we can investigate what kind of operation it contains, and which addresses are involved
If listener supports filtered events, we can create a filter in a way that will report only event of interest
Link to draw.io file:
Link to draw.io file
Sequence diagram shows sidechain listener interactions with the rest of the sidechain components.
As the implementing blockchain listener is highly blockchain specific task, we will not put any constraints on a listener implementation or require specific interface. Listener should be implemented any way it works, and sidechain handler task is to process input from event, use communication interface, if needed, to get the minimum required information about transfer, and pass it to higher level of processing.

Title: Wearable Antennas for WBAN: Design Considerations and Assessments
Speaker: Dr. Ping Jack Soh
The increasing demand for multi-functional, multi-band wireless operation and consumer-centric technology have motivated major developments in wearable antennas. Future wearable systems should be unobtrusive, flexible, and operating with minimal degradation in proximity to the human body. These antennas have to meet bandwidth, efficiency and safety requirements, while being consistent with low cost manufacturing techniques. Moreover, in wearable applications, flat surfaces cannot be guaranteed. Thus, an important antenna requirement is its ability to work with good robustness against environmental, positional and location changes when being worn, besides complying with medical and safety regulations. Such body-centric antennas are capable of catering for various current and future wireless standards and applications. Among others, wearable antennas could assist medical monitoring for hospitalized, home-bound, or outpatients; facilitate communication for emergency services and public safety support; and in search, rescue and location-tracking alerts. However, degradation of the antenna performance when worn on the human body has been one of the major deterrents in its successful implementation, be it in terms of frequency detuning, bandwidth reduction, and efficiency degradation or radiation distortion. Ideally, a wearable antenna must be designed to be immune enough for an on-body operation. This talk will provide a brief overview of the types of wearable antennas, with a specific focus on fully-textile antennas. Next, the design considerations will be discussed, prior to the recommendations on modified/specialized characterization procedures using a commercial setup for the assessments of these antennas. Finally, a summary of available fabrication technologies will be discussed prior to the conclusion.

This project focuses on questions of stability and metastability for stochastic dynamical networks. On the one hand, in view of the high complexity of large networks as they occur in many applications, we will extend the approach of isospectral transformations for deterministic dynamical networks to a variety of stochastic networks. The goal is to simplify a given network systematically in such a way that its stability or metastability can be studied for the simpler network. On the other hand, we will address the effect of noise on the dynamical properties of certain classes of networks such as feed-forward networks and coupled Hamiltonian systems.

If you’re likely to spend more than a year of your life up in space, you want to be absolutely sure that every safety measure is taken each step of the way. Such is the reality for British/American astronaut Michael Foale and his colleagues.
Foale, who has six missions behind him is now commander of the International Space Station. He is also part of a team working on the development of robots for use in space that includes the Bosch sensor system, SoundSee.
All machines have their own ”noise signatures”. As the name suggests, the Soundsee device “sees” problems in the International Space Station (ISS) using sound recognition. A collaboration project with NASA, it helps the ground control team analyze information on the noises emitted on the station and provides early warning signals if something is wrong. It not only helps detect faults otherwise invisible to the eye, but it can also save valuable time if repairs or replacements need to be made.
A box roughly the size of a small portable speaker, Soundsee roams around the space station on the back of NASA’s Astrobee Robot while an AI algorithm using machine learning can then help the team analyze and understand the sounds emitted.
Although the device is being used on the ISS, the wider potential is obvious. After all, if it’s good enough for the ISS, surely it’s good enough for everyone else?
And this is where the commercialization of space comes in, with the number of “tourists” set to rise dramatically in the coming years. Clearly the appetite for space travel remains as great as ever despite the sky high price tag that comes with it.
In terms of numbers, throughout the entire history of space flight, only a little over 500 people have undertaken the journey. That number could actually be matched every year if the likes of Virgin Galactic are to have their way. And that opens huge potential for business of all kinds.
A primary benefit of Soundsee is that it can be adapted in all sorts of ways and in different sectors. One principal benefactor is likely to the agricultural industry, for example, where the device can be placed on farm machinery to detect not only dangers that are difficult to see, but also keep track of the condition of machinery.
“This is a really important factor” says Ralf Martensson, Business Development Manager, Nordic, Robert Bosch AB. “Basically this kind of technology can be employed almost anywhere where something needs to be recognized and monitored. That could mean anything from a coffee machine to a huge engine on a ship, or in factories and so on. There really are no limits as to possible user cases,” he says.
“I see projects such as Soundsee as high-end solutions for extreme development that can be used in the future in other products that don’t necessarily need such extreme quality. If you want a comparison, you could just look at the relationship between Formula 1 and ordinary cars,” Martensson adds.
Meanwhile, back in space, Soundsee isn’t the only project Bosch is working on. It is also teaming up with NASA as part of so-called Tipping Point program. Here, the remit is to provide research and develop technology to intelligently navigate and wirelessly charge small robots for operating on the moon.
The Nordic region is involved in the space race too, courtesy of its work on the BMI160 sensor from Bosch Sensortec that is used on the Mars Rover and also in Lund, Sweden, where the Bosch R&D Center is also working with Bosch Sensortec, adding AI into the sensors.
What all these projects underline is the ongoing search for new possibilities at Bosch. And while space itself may not currently be a major business area for the company, the work going on clearly has wider implications.
Perhaps, space may not be the “final frontier” after all.

The NASA-JPL Mars Exploration site overviews of all previous, current, and planned US missions to Mars, with links to project homepages and other information.|
operational: MAVEN: Mars Atmosphere and Volatile EvolutioNA new Mars orbiter, the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, was launched on November 18, 2013, atop an Atlas V-401 vehicle. MAVEN entered Martian orbit on September 22, 2014.
MAVEN will attempt to determine how much of the Martian atmosphere has been lost over time by measuring the current rate of escape to space and gathering enough information about the relevant processes to allow extrapolation backward in time. MAVEN is the first Mars mission managed by the Goddard Space Flight Center. The University of Colorado's Laboratory for Atmospheric and Space Physics will coordinate science operations. MAVEN press kit, 2mb .pdf
operational: Mangalyaan Mars Orbiter MissionIndia's first interplanetary probe, the Mangalyaan Mars Orbiter Mission, was launched by the Indian Space Research Organisation (ISRO) from Sriharikota, Andhra Pradesh (near Chennai), atop a Polar Satellite Launch Vehicle (PSLV), on November 5, 2013. Mangalyaan entered Mars orbit on September 24, 2014. Wikipedia: Mars Orbiter Mission
operational: Mars Curiosity Rover & Mars Science LaboratoryNASA's Mars Science Laboratory mission, run by JPL, was launched on Nov 26, 2011 at 10:02am EST from Cape Canaveral atop an Atlas V 541 launch vehicle.
MSL rides on the "SUV-sized" Mars Curiosity rover, weighing 775kg (1700lb), and carries instruments including cameras, spectrometers, radiation detectors, and a weather monitoring station.

operational: Mars Reconnaissance OrbiterThe NASA-JPL Mars Reconnaissance Orbiter was launched on August 12, 2005 at 7:43am EDT, on a Lockheed-Martin Atlas V-401 launch vehicle with a Centaur upper stage. The MRO was successfully decelerated into an elliptical Mars orbit on March 10, 2006. From March until November, the MRO was aerobraked, using friction with the atmosphere of Mars to slow down into a lower, circular orbit.
Since November, 2006, MRO has studied the history of water flows on Mars, and mapped the planet with HiRISE, the highest-resolution camera (1-meter) that has ever flown on a planetary mission. 2 other cameras, CTX and MARCI are also on board.
Science instruments MRO carries include CRISM, a spectrometer to identify surface minerals, MCS, a radiometer to examine the atmosphere, and SHARAD sounding radar to search for water ice over one meter below the surface, and more.
MRO was scheduled to conclude its science ops in Nov 2008, but the period was extended, and science ops are still underway. MRO might also be used to relay data from Mars surface probes until as late as 2015.
operational: Mars Exploration Rover OpportunityThe first of two NASA-JPL Mars Exploration Rovers, MER-A or Spirit, was launched on Tuesday, June 10, 2003, and landed safely on Mars on Jan. 3, 2004. Spirit covered about 7.7 kilometers until it became stuck on May 1, 2009; contact with that Rover was lost on March 22, 2010.
The 2nd rover, MER-B or Opportunity, was launched on July 7, and landed successfully on Jan. 24. As of January, 2015, Opportunity had traveled over 40 kilometers on the Martian surface, and was still functioning, though having some trouble with its flash memory. Both rovers, more capable than the earlier Mars Pathfinder (July-Sept 1997), have sent back a wealth of photos and data.
operational: Mars Express OrbiterMars Express, was launched on June 6, 2003, by the European Space Agency (ESA). The Mars Express orbiter carried with it a 73-lb. British lander called Beagle 2. Beagle 2 separated from Mars Express on Dec. 19, 2003, and was to land on Dec. 25th, but no signals were heard from it.
The Mars Express orbiter successfully entered orbit on Dec. 25th; it is the primary vehicle of the ESA mission. ESA Multimedia Gallery
operational: Mars Odyssey OrbiterAn earlier US Mars orbiter, Mars Odyssey, has relayed some of the data back from the Mars Exploration Rovers. Mars Odyssey entered Martian orbit on October 24, 2001.
Odyssey maps chemical elements and minerals on the Martian surface, looks for water, and analyzes the radiation environment around Mars.

Mars Spacecraft No Longer OperatingNASA's Phoenix Mars Lander mission was being run by the University of Arizona's Lunar and Planetary Laboratory at Tucson. Phoenix was launched on Saturday, August 4, 2007, from Cape Canaveral atop a Delta II launch vehicle, and landed in the northern polar region of Mars on May 25, 2008. Phoenix carried a robotic arm which dug beneath the surface and verified the presence of water-ice in the mildly alkaline soil. Also found were small concentrations of salts, including perchlorate salt, and calcium carbonate. By November, 2008 Phoenix had ceased to function, as expected, due to the cold of Martian winter. mission summary - photos
Until Nov. 2006, the Mars Global Surveyor relayed some data back from the Mars Exploration Rovers. MGS entered Martian orbit in September, 1997. The spacecraft was aerobraked to a lower orbit, and began mapping the planet in March, 1999. On Nov. 2, 2006, the signal from MGS was lost. By this time about 240,000 Mars images had already been sent from MGS to Earth, including photos which suggest that running water might still occur occasionally on Mars.
Russia's Phobos-Grunt (Phobos Soil) was a mission intended to return a 200 gram (7 ounce) sample of soil from the Martian moon Phobos to the Earth. The spacecraft, along with a small Chinese Mars orbiter, was launched on a Zenit-2SB41.1 rocket on Nov. 9, 2011. However, after the spacecraft reached orbit, all communications with it were lost, and the planned automatic engine burn to put the craft on a trajectory to Mars did not occur. Phobos-Grunt reentered the Earth's atmosphere in early January, 2012. Phobos-Grunt at RussianSpaceWeb.com - Spaceflight 101

3dcd, LLC (a joint venture of OpSec Security and Technicolor) chose Interwoof to help develop 3dcd’s CDI (Coherent Diffractive Imaging) technology. 3dcd’s CDI system uses advanced graphic design software and high-speed signal processing technology to record unique super-resolution diffractive images using conventional optical disc laser beam recorders. CDI diffractive imagery has been used since 2010 by major software producers and optical disc manufacturers to protect over one hundred million CDs, DVDs and Blu-ray discs made at more than 10 secure manufacturing locations worldwide. Interwoof wrote the sophisticated software used by graphic designers to create the CDI design files, and further engineered the advanced signal processing equipment integrated to the laser beam recorders for recording the CDI imagery.
More about CDI
Interwoof developed a RF (Radio Frequency) paper encoding/decoding system for Glatfelter, a major manufacturer of specialty papers. The system allows rapid verification of the unique RF signatures in individual sheets of paper. This technology has wide applicability for counterfeit detection in a broad range of high value documents.


My Son Got Shocked by a D Cell Battery [closed]
Every electronics engineer that (nearly) zapped him/herself with mains power as a kid and denied to parents about having done anything that was forbidden raise hand (vote up). 1 for myself.Do not do this at home!, but on the plus side, ever since that very day I have huge respect for these seemingly innocent copper wires. The shaking knees wore of in a couple of hours.1. Does anyone else think that those magnetic leather cell phone cases kill your cell battery????Those cases are perfectly safe for cell phones. I've used them for years with no problems at all. The magnets in the cases are strong enough to keep the cases closed, but not strong enough to do any damage to the phone.2. My new 12 cell battery won't charge. Do I need a certain type of adapter?I bought a cheap iPod car charger (Will never do that again!) and it did not work! My guess would be that there was/is something wrong with the adapter part, or the cable3. dead battery can i tell if i got a dead cell with a battery tester?You can take the battery to an auto parts store such as NAPA, and they will test the battery for free. The only other way I know of is to charge the battery and use a volt meter to see what voltage the battery is operating at. If a cell is dead, it will operate at less than 12 volts.4. Can anyone tell me that how to make an electromagnet with a cell(battery) of 1.5 V?simply coil a wire to a metal, preferably an iron, but a screwdriver also would do. then attach the end of the wires to the battery. presto, you got the electromagnet. I also prepared a research for you. Electromagnet, device consisting of a solenoid (usually a cylindrical coil of insulated wire wound in the form of a helix), in which an iron core is placed. An electric current passed through the coil induces a strong magnetic field along the axis of the helix . When the iron core is placed in this field, microscopic domains that can be considered small permanent magnets in the iron align themselves in the direction of the field, thus increasing greatly the strength of the magnetic field produced by the solenoid. The magnetization of the core reaches saturation once all the domains are completely aligned, and an increase of the current in the solenoid has little further effect. When the current is switched off, the core retains only a weak residual magnetism. Microsoft Encarta 2006. 1993-2005 Microsoft Corporation. All rights reserved.5. Would a new 9-cell battery charge on my old 6-cell battery adapter?yes,it fits ok do not worry6. help to keep my cell battery alive for longer than a few hours!?Charge it every night ! Leave it on for a while over 4hours. Then it should be fully charged x7. How to tell difference between a cell and a battery?a battery z a combination of cells8. what common household items have the 3v cell battery?3v Watch Battery9. Is there a button cell battery I can use as a substitute for AA's?No, there is not10. how do i make a wet-cell battery?You can probably make a voltaic pile out of pennies, nickels, kitchen towel (if you can not find blotting paper) and vinegar Or a single cell with a cup of vinegar, a steel nail and some copper wire11. Customized Laptop! (how long will the 12-cell battery last)?You have configured a very high end laptop, a true desktop replacement, using very much power hungry components. A 12-cell battery would last around five to six hours under constant use, if I would have to give an estimate, due to the components you chose. The specifications you list are actually too much for just playing a game such as Counter Strike. You could do with a much simpler configuration. However, if you would like your laptop to be future proof, then you are definitely on the right path. You list that you will be using Windows 7 Ultimate. Please make sure that this is a 64-bit version of the operating system. If it would be a 32-bit version, then 8GB of RAM is overkill, as a 32-bit operating system cannot allocate more than 4GB of RAM, meaning that the other 4GB of RAM will not be used, but it will still consume power by the way. Normal laptop hard drives have a RPM of 5.400, whereas the hard drives which you list are 7.200 RPM. This means that the hard drives are faster than normal laptop hard drives would be. They have the same amount of RPM that most hard drives in desktop computers would have, so this will give you a good performance boost. The performance difference between one 500GB hard drive or two 320GB hard drives depends on how you configure your system. If you would choose to mirror your hard drives, then you would not gain any performance. Mirroring two hard drives does provide fault tolerance however. If you would use one hard drive for your system files and software and you would use the other hard drive for your data, you would gain performance as both hard drives can be read from and written to at the same time. If this difference is noticeable however, depends on how much data you would read and write simultaneously. I would personally always choose for the two hard drive set up, as even the most little performance gain is welcome and it allows you to run a dual operating system set up more easily, as you could easily use one hard drive per operating system. As for the weight of the laptop, have a look at the HP website for how much the base model weighs and add the weight of the larger battery and an extra hard drive and you will round and about be correct.
