iTunes Match
A spokesperson for Apple was keen to clarify at All Things D-shaped correction of all media - including us - with iTunes Match described as a listening service streaming. Match iTunes would use a local cache: pressing the download button triggers not playback of a song streaming pure remote, but downloading a song in AAC format 256 local pieces read as it is downloaded.
Streaming requires a constant connection to the server, the file being downloaded piece by piece. With icloud, Apple does things differently: the 256 AAC file is downloaded in its entirety in the local cache, allowing in particular, as long as the connection is good, start playing immediately and to move forward through the song without waiting for buffering. This system is also more easily deployable on a large scale: concurrent connections for streaming could bend mobile networks and degrade the user experience.
But in the end, no matter: the same way that most users do not know about Specify its elaborate system of P2P (and time of Hadopi and shortcuts coarse it entails, it is better that they know nothing about), most users do not care about the precise operation certainly not Match iTunes.
Apple is indeed everything that his system is like the hardcore streaming from the perspective of the user. While the song is downloaded in the local cache, switch to airplane mode and you cannot read it. Apple can be dispensed to provide a system for managing the size of the cache: it denies the existence of the local cache. While the song is downloaded in the local cache, it will be seen as downloaded by the system if the user has explicitly pressed the download button.
While technically there is only one step - download the song - Apple separates for the user to listen and download, to facilitate understanding of the system. Music "rises" in the cloud of your iTunes icloud automatically; you can play a song directly in the cloud or to "descend" to your iPhone or your iPhone by pressing a button. Never mind the semantic and technical discussions are certainly important for a fringe of users, but are similar to all other pinailleries - provided that the system works.
Virtualization with Parallels Desktop Lion 7
First, it will be recalled with Leo, Apple allows users to virtualize its system software provided of course that it is run from a Mac. Previously, the Apple brand store for this possibility to edit "Server" Mac OS X Parallels Desktop is the first virtualization solution to allow it (without having to tinker) but there is no doubt that VMware and Oracle exploit this feature very soon in their respective software.
Installing OS X Lion is simple, but slow. Parallels Wizard starts the recovery partition and prompts you to install Mac OS X 10.7 on your virtual machine. The biggest problem with this approach is that it is better not to hurry. The installer must before starting his work to recover the archive to install OS X Leo. It is not without problems for those who have acquired the USB Mac OS X 10.7. Despite a good ADSL connection, the installation process has taken two to three hours. After the installation is completed, the virtual machine restarts.
Then, like any virtual machine, you are prompted to install the Parallels Tools. The application mounts a disk image on your desktop. You just have to start the installation as with any software. As with any virtual machine, Parallels allows you to set a range of parameters: amount of memory, graphics acceleration, storage ... As with any Windows virtual machine, you can also exchange files between your Mac and Mac virtualized. In performance, the results are quite honest. Your Mac is more powerful and more RAM you have, the better it will be. It should be noted that the coherence mode that allows you to melt the windows of Windows applications on your Mac can not be activated, but the interest of this feature with Mac OS X is very limited.
2010 on a MacBook Air Core 2 Duo 2.16 GHz with 4 GB of RAM, performance is completely honest. As always with virtualization, we feel the limits of this process as soon as you begin to make sustained use of the graphics processor. On the other hand, the fan of the MacBook Air can be heard more than usual.
Out of curiosity, we tried to install Snow Leopard in a virtual machine. In this case, the application displays a short message reminding that Apple does not allow the virtualization of this version of Mac OS X. It is not officially unofficially making do, it is always possible. In any case, it is unfortunate for those who depend on it for one reason or another Rosetta. Recall that a demo version of Parallels Desktop 7 [260 MB] functional for 15 days is available for download.

A New Technology Video At Apple?
The Wall Street Journal writes "Apple is working on a new technology to stream video to TVs, and has discussed the opportunity to launch a TV subscription service ".
The second part is not new, since at least 2009, we hear from Apple will offer packages of content for television, on a subscription. Thus it would compete with cable and satellite. This has not yet translated into action and Steve Jobs later acknowledged that the proliferation of boxes with their TV services and VOD integrated complicated task for those who wanted to enter this market.
Regarding the supposed new technology, the veil of fog is thicker still. Is it for example promotes the integration of the AirPlay TV (but would bypass the Apple TV)? Vague formulation of the WSJ leaves the field open to all interpretations of how Apple wants to bring something new on the transport of these images.

Market Shows Serene Confidence On Apple
We were expecting to see the market reaction to the announcement of the withdrawal of Steve Jobs, they show a relatively serene confidence, since the close of Wall Street, not accusing AAPL a loss of 0.65% lower than the Dow Jones (-1.51%) and NASDAQ (-1.95%).
This figure should be put in perspective with the performance of the day, while AAPL was up 5%. The scholarship has noted the change in position of Steve Jobs, would not seem particularly moved, and then displays a relative confidence that Apple continue its momentum after the change of helmsman.
The smooth transition will have paid all we could see Tim Cook at work during the sick leave of the founder of Apple. If the Cupertino company would soon make an announcement as we suspect more and more, turning this small market will be gone as long as it is increasing in the coming days.
