Understanding what WiTricity technology is —transferring electric energy or power over distance without wires—is quite simple. Understanding how it works is a bit more involved, but it doesn’t require an engineering degree. We’ll start with the basics of electricity and magnetism, and work our way up to the WiTricity technology. Electricity: The flow of electrons (current) through a conductor (like a wire), or charges through the atmosphere (like lightning). A convenient way for energy to get from one place to another! An illustration representing the earth's magnetic field Magnetism: A fundamental force of nature, which causes certain types of materials to attract or repel each other. Permanent magnets, like the ones on your refrigerator and the earth’s magnetic field, are examples of objects having constant magnetic fields. Oscillating magnetic fields vary with time, and can be generated by alternating current (AC) flowing on a wire. The strength, direction, and extent of ...

Flexible battery Recently developed a new technology for constructing the elements of power, which will make the battery flexible and, obviously, largely change the face of portable devices. New ultra-thin lithium-ion batteries are actually based on a sheet of paper - this way achieved properties such as flexibility and light weight. The results of the research were published in the journal ACS Nano scientists from Stanford University. According to the presented materials, the thickness of the ne w batteries can reach 300 micrometers. In doing so they have a high energy density and have functional advantages over other types of thin batteries. In order to create new batteries, Stanford experts on materials with hard base surface with a thin film of carbon nanotubes on top of which was covered by a layer of metal-based lithium. Thereafter, the resulting structure was placed on both sides of an ordinary sheet of paper. Thus, a layer of lithium acts as an electrode, while the nanot...

Company TDK have developed a prototype optical disc volume in 1 TB. The disc contains 16 layers on each side of the disk, and each of them can write 32 GB of data. If you watch the race, optical drives, you probably remember the prototype of Pioneer's 400 GB and even 500 GB, up to now this figure has remained the record. As for the new development TDK, that the creators did not say directly that this drive Blu-ray, although it is made from virtually the same materials and can work with the same laser beam. About the commercialization TDK claims that it will depend on producers.

it is soooo easy to hack these devise because you can just remove hes memory and connect it to a computer !!! , yes the is all , the modu memory including the system files on Micro SD card !! : that what i did for fun - hehehe My TUX INSIDE !!! The Modu System files SDA1 : Download . and using "dd if=/dev/sdb3 of=sdb3 bs=1048676^C" we got sdb3 : Download . keys : modu hacking JACKET הפלאפון הקל ביותר בעולם פריצת פריצה מודו

the tip of the day : "sudo !!" , will , that happened that you try to install some think like apt-get install some-think . and you get error ? because you are not the root user , so you can just try "sudo !!" after that , and he will repeat the last command using root permission cool haa :)

soo all we need is first to install the ssh server on the server - machine we like to control so - 1. sudo su 2. apt-get install openssh-server . . now back to our machine using the ssh : 1. ssh -V -X username@the-server-ip 2. enter the password and that is it now we can run any GUI application that install on the server using his CPU cycles yahhhh great !! for example lets run WireShark : 3. gksudo wireshark & now all that if we runing tow Linux machines !! but what windows users that like to run a linux app??! !! soo we need it tow applications 1. putty you can get it here : http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html 2.Xming you can get it here : http://sourceforge.net/projects/xming/ ok so first we need to install Xming , and after that we going to use butty but we need to cheak Enable X11 forwarding in connection -- > SSH -- > X11 >> Enable x11 forwarding . and that is it free to run any linux application on windows using SSH . have fun ...

, chrome אחרי חודשים לעליתו של הדפדפן הענק של גוגיל קפץ לי לראש בקצב עלית המשתמשים של ה דפדפן בטח גוגיל עובדת על משו דומה ל מכשרי סלולר כמו שאר החברות , firfox או opera "chrom mobile " לכן חיפשתי לצערי לא היא בתוצאות דבר מעניין אלה רק שמועות !! ואז נזכרתי שנייה מה עם chrome os ואלה !! אפו זה נעלם מזמן לא שמעתי על המערכת הפעלה הזו הם אמרו ש נהפוך עם זה את העתיד אבל אפו זה היום לכן נשאלת השאלה האם באמת the google os is a fail ? את השאלה הזו נתן לכם !!! לענות

Switzerland, a longtime haven for all kinds of financial shenanigans, has just expanded its reputation for "discretion" to cover file-sharing as well. That's the conclusion of Logistep AG , anyway, as a Swiss court has just gutted its P2P surveillance business with a ruling that says gathering even publicly available information is illegal. Logistep has operated in Switzerland since 2004, doing what all of these firms do: trolling BitTorrent sites for movies, music, or software, then connecting to swarms and logging the information of everyone offering the file. Bits of the file are downloaded as proof that these aren't simply "mistitled" files, and information like IP address, file hash value, and time of day are recorded in a giant spreadsheet. Content providers who rely on Logistep can take this information and submit it to local courts, seeking to identify and then sue individual file-swappers. But Europe has fairly strict data privacy laws and a cultura...
