Safari 4: browser of Apple this time it mean

For the time being it is a bipolarismo. Internet Explorer for the mass, Firefox for the smanettoni. In this fight Apple tries to thread itself, with its browser Safari, reached version 4. The program, available or on Mac that on Windows, is currently in phase beta and introduces innovation a range wide, in primis those developed in order to render the reading of the pages faster and effective web.
According to brought back how much, the new motor Javascript would concur a speed of advanced execution approximately 4,2 times with the precedence version 3. In it upgrades them comparison with the browser would turn out, under this aspect, 3 times faster than Firefox and, quite, 30 times regarding Internet Explorer 7! Philip Schiller, vice-president for the marketing of Apple, has declared that Safari 4 will not only be the browser faster, but will be also that one in a position to re-uniting all the standards of development web puts into effect them, integrating HTML 5 and CSS 3 perfectly. The demonstration of the goodness of the new one browser is in the result of acid the test, exceeded to full ballots (100/100) from Safari 4!
The graphical formulation introduces an interface in pure Windows style with characters, bar of the title it, profiles and toolbar online with the aspect of the operating system Microsoft. The tab of navigation drops have integrated the function “drag and” in order to organize the cards in more windows of the browser. Quickly visible innovationes are the function “Top Sites”, a kind of page preview, available quickly to the start, that it more contains the sites visited and the function “Cover Flow frequently”, an equipped “upgraded” chronology among other things of a preview of the pages visited and of an express it arranges of search between the result.
The new one browser is already releasable in both the versions (Mac and Windows) on the official site. Draft, however, always of a beta test, therefore of a already stable version but to perfect in the last details. Not there is still a date for the official release, but if the result will confirm the waits it will be alone issue of some weeks.

Towards the electric current wireless?

Tried to imagined the technological truth of the next future: they are sure that you will think next to devices connected via wireless, bluetooth and infrared, to the wiring reduced to the single electric power supply. Mistaken! Perhaps not there will be not even the feeding cables. They are in full phase of development some solutions that allow to transmit to the electric current without some support: at the moment three technologies in a position to replacing the simple cable are known very.
The first technology, adopted from the Powermat, takes advantage of a principle of the very famous physical: the magnetic induction of the current. The objective is to induce the electric current generation through a containing surface the devices to feed thanks to the guideline and the intensity of a magnetic field source.
A second technology, enough similar, has been developed from the MIT (Massachussets Institute of Technology): in this case the transfer happens through two coils. One of they, connected to a taken electrical worker standard (like one of the many that we have now in house), generates a magnetic field in which it is found “dipped” the second coil. In this second coil, for magnetic induction, electric current will flow.
A last and most interesting solution has been devised from Intel: an antenna that with to a converter transforms the radio waves in band VHF or UHF (those of our stations TV in order to be understood) in continuous electric current for feeding any type of device.
Fantascience ? It would not be said, at least according to the Ministry of the Japanese Communication: the Japanese ones assume a standardization of the technology in times breviums to the aim to develop it in the details and in order to concur of the production of mass within 2020.
