The High-definition: new pleasure in DVD!

The high-definition arrives finally in our homes. Of quality higher to the DVD than we know all now, it exists however in two formats: the HD DVD and Blu-ray. Future substitutes of the DVD, these formats have the same diode with blue laser (the diode of the current DVD being red), and use the same algorithms of compression.

HD DVD: enough near technically to the current DVD, it is easier to manufacture and thus less expensive. Its storage capacity is from approximately 30 Go and the readers should be less expensive than its competitor.

Blu-ray: of higher capacity (one announces 200 Go! ), actually 25 Go at its exit, this format has a layer of protection much finer. The maximum flow makes it possible to have less compression and thus an image of higher quality.

For the level of the film editors, it should be known that Blu-ray has more support than HD DVD. But extremely fortunately, the manufacturers of the new readers of DVD will allow the users to look at the old DVD. During one transitional period, it is completely normal to avoid with all the platinum owners systematically changing material. On the other hand it will not be possible to read the future DVD with our current readers.

The diffusers, TV, Plasma, screen LCD, or video projector must comprise the ad hoc connector industry to profit from High-definition quality. A catch DVI or HDMI is essential. Side television set, the initials “HD-Ready” will be the paramount purchase to supplement the chain of the High-definition. And as soon as the prices drop, you will be able to direct yourselves towards the diffusers posting “Full HD”

Even if the recorders of DVD do not ensure for the moment any compatibility with the High-definition, the new DVD, HD DVD or Blu-ray promise beautiful hours of visionnage to us. Then all with your living rooms and your rooms of home cinema!

How to carry out a room homecinéma without ruining itself? It is the topic of the site of the author: http://www.salle-homecinema.com

With discovered framework digital photograph!

If you like to take photographs with all goes, a framework digital photograph is the ideal solution for you. The latter glad indeed not to post only one photograph as a photo framework traditional, you can make ravel all your photographs continuously in an automatic way to the manner of slides. The quality of posting of the executives digital photographs today on the market is really satisfactory, contrary to their beginnings.

However before you will buy your framework digital photograph there are some small things to know about those so that you make a good purchase.

First of all you ensure that the framework has a good resolution. The clearer it will be high, and “sharp” will appear your photographs. The executives digital photographs have screens LCD. They are exactly the same ones as those used in televisions, in smaller of course.

If the photo framework which you like suffers on the level resolution, pass-therefore your way. The resolution of the screen makes such a difference in quality of the image which one should not haggle over this aspect.
There exist several resolutions, I advise you a mini resolution of 640x480, or better of 800x600 if you have the means of them. The larger your screen LCD will be (10 inches and more), more it will be important that the resolution of this last is high to offer a good quality of image.

Another point important to take into account is the ratio of your screen. There exist two ratios for the executives digital photographs, 4:3 and 15:9, the ratio 4:3 being the ratio used by the majority of the compact numerical cameras.

Consequently a framework digital photograph with the ratio 4:3 will probably as well as possible restore your photographs in their original aspect. However the ratio 15:9 will give you an image broader cinema type.

Unfortunately, if you post images in 4:3 on a screen in 15:9 the top and the bottom of the image is cut, which could displease to you.

Check that the framework digital photograph that you think of buying accepts the same type of memory card as your camera. Certain frameworks accept multitudes of different charts for more versatility. Certain frameworks are also equipped with a port USB.

The options are numerous: wifi, loudspeaker, alarm, video capacity, etc of course more these last are numerous plus the note will be salted. Finally will know that there recently exist numerical photo key doors which are the counterpart of their big brothers but who are much more portable. The key door digital photograph of course does not claim to replace the framework digital photograph, both do not aim the same market. The key door digital photograph is right average a sympathetic nerve and tendency always to have its best stereotyped on oneself.

The man and technology

The man is not only the creator of technology, but it there has also a process by which the man becomes depend on technology and is formed by it. The history of the mass media is marked by great technological mutations which, with various stages of modification of the means of production, the diffusion and the consumption of information. Once the new supports such as tapes or satellites, electronic or optical were created, we had to live one of these changes of the digital revolution, and which, according to us, will have important consequences on our way of communicating, to work and to divert us.

The study of new technologies of the communication cannot, still, being reduced to the study of the use and the effects positive or negative on the company. The creation of new technologies of the communication is not only the result of an obvious scientific progress, but also the expression of the economic policy or strategies. All cannot be reached by technology, of course: the operation of the communications tools is subjected to certain elementary rules and of the principles, which we have need to include/understand.

But if technology has rigid elements, it is opened with a large range of replacement solutions and can be the object of very diverse applications. This difference between the capacity to make technology and will to make social actors illustrates the particular relation with each company with technology, explaining at the same time, the diversity of the effects of new technology. Each one of us, for whom data processing became an object usual and necessary, we found ourselves at least once so much in anger which we want to destroy the computer. And certain people really succeeded in doing it. Then, despaired, because they had lost important information, they called so that they have news of various sources to repair what they did. (Because we must admit that the man is the principal enemy of the computer). In the majority of the cases, the recovery of the data is carried out by people or companies.

The acceleration of the changes, the shock of the future, the impact of technology on nature and the company, the passage to high technology require the technological teaching which will make it possible the man to be able to better exploit new technology. Thus, the man will be heard in his uninterrupted effort to reach the perfection, the development and the multiplication of his force and direction using instruments and of machines, the products of technology (telescopes, radars, of new energy sources), to communicate through the sound and the image (to include/understand and use the functional structure of a send-receive), to extend in space and to reduce the distances by the means of transport, to release themselves from hard, repetitive work (using robots), to multiply his capacities to get information and to work with information (comprehension the operation and the exploitation of the computers different types), implying itself in œ uvres of creation, and in order to arrive at the harmony with nature and to avoid the lack of balance, to learn constantly from nature. Therefore, the man uses technology to make his life easier, but it also needs a higher intelligence, in order to maintain balance.

How to arrange and take along its CD with oneself

It was a time or each product had its own support, the music on the audio cassette, the film on cassette VHS, etc Each place of the house made it possible to arrange its various supports which took much place quickly.

With the development of CD and similar supports like the DVD, one allowed to put any type of data on the same support that it is video, audio, photographs, or any other file.

The big problem, it is now to correctly arrange its CD considering which one has more and more, between Films in DVD, the albums of music, the recordings of the photographs of holidays and the other data significant of the computer which were recorded.

The columns of arrangement make it possible to lay out a certain quantity of discs in an elegant way. One finds some out of wood, plastic or out of metal. The styles vary and one will be able easily to find a piece of furniture retro for his traditional interior, or an elegant metal column to go with his modern decoration. The big problem of this solution of arrangement, it is the place taken and impossibility of taking along its best CD with oneself during the holidays.

The solution, it is the sorter arranges Cd which makes it possible to arrange in each page, four discs (or less for the small sizes). One can thus take along about fifty discs with oneself, one can quickly divide into sheets the pages to fall on what one seeks and one can even decorate each site using a small pocket with the format CD (a jacket of an album for example) to find oneself there more easily.

How to buy a portable GSM?

It became essential, but how to buy a cellphone

Battery (autonomy)

Your telephone must be able to hold during one week in mode takes care. To reload its telephone every 24 hours belongs to another time but all will also depend on the use that you of made, the mp3 and the photograph can flat put your batteries in a few hours.

Camera and video

To ensure you that your mobile has a resolution of at least 2 million pixels, that will enable you to take photographs and to very produce vidéos of good quality

The screen

The screen must be enough coloured to read its emails, of the vidéos, to receive ms.
A model equips with a screen posting 65 ooo colors is acceptable

Bluetooth

The standard bluetooth is important for the transfer of your files without wire.

Personalization

You must have the possibility of personalizing your mobile, to install ringings of Poly quality and HIFI
The possibility of installing applications or plays in language java

Memory

if one uses the functions MP3, e-mail, to store photographs or vidéos, one may find it very beneficial to choose a model equipped with a sufficient memory because the storage of documents and the software can quickly encumber and saturate the telephone.

if there are really large needs as regards memory, it will be necessary to choose a telephone equipped with a reader of memory card, only solution, at present, to reach capacities compatible with a multi-media use.

Other favours with this last solution, the charts being interchangeable and the evolutionarity of the telephone of is increased as much by it.

On a journey

If you travel abroad regularly, your telephone must support the standard quadribande, that guarantees to you to be reachable in any country covered by network GSM (either more de150 country at present).

Your budget?

The price of your telephone will depend initially on the context in which it is sold to you: with or without fixed price.

Without fixed price, count approximately 100 euros for the simplest models and a minimum from 200 to 300 euros for the models with the most pointed design and the most advanced functionalities

Is a home-cinema, for what that used and which is its interest?

The recording of a music is all the more perfect as it restores this one accurately, with the possible minimum of additions. It is a question of hearing the voice of the artist or the instrument which accompanies it in their purest form, as if they were in the part with you.

With the cinema, on the contrary, each sound that you perceive is an artifice. Nobody forever on the occasion to record the crash of an airliner which breaks into two, nor the howling of a tyrannosaure. These sound effects that one hears with the projection of a film are only supposed approximations to reinforce the cinematographic experiment of the spectator by convincing sounds which impress it.

In fact, all the sounds appearing in the original soundtrack of a film are generated after turning. The dialogues are recorded in studio and the music added thereafter, as well as the sound effects coming from a range of audio sources, sometimes unusual. The “biological” sounds, like the noise of the whales for example, are used to reinforce the basic effects in the noises of explosion. The decisions relating to the sounds and the adjustments of the band are made by the sound designer. This one must take into account a crucial factor - the dialogues, which it is constrained to preserve. Indeed, the realizer of film is there to take care of the clearness of the dialogues and does not hesitate to sanction any unusual sound effect.

This distinction is very important, because it helps us with better including/understanding the operation of a home-cinema compared to the loudspeakers mp3 iPod. Contrary to the systems hi-fi, like the station of reception iPod, the principal function of the home-cinema is not to reflect reality, but to recreate it. With this intention, the best systems must be able to give the impression to the house than one is in fact with the cinema.

Blu-ray Disc (data base), the technology adapted to Televisions High-definition

This new format was developed to allow the recording, the gravage and the reading of the video High-definition (HD), but also to store a great quantity of data. The name Blu-ray is derived from the technology which is at the base of this format and which uses a purple blue laser for reading and engraving data. The name is a combination of “Blue” (the purple blue laser) and of “Ray” (optical ray). The format Blu-ray Disc was developed by the BDA (Blu-ray Disc Association), a leader group in the field of the consumable electronic ones, the personal computers and the media and which gathers more than 180 companies members everywhere in the world.

Concerning its specificities, this format offers more than five times the storage capacity of the traditional DVD of today and can support until 25GB on a disc on only one surface and until 50GB on a disc on double surface. Moreover, one can put more than 9 hours of video high-definition (HD) on a disc of 50GB and approximately 23 hours of video of standard definition (SD) on a disc of 50GB. The format also supports the audio formats with high-definition and without loss of sound. As for its resistance, the DVD Blu-ray do not require for cartridge of protection because Blu-ray takes care some in the place, which makes the disc much more resistant to the scratches and the digital fingerprints that the traditional DVD, while preserving same appearance however.

On the level of the costs, the Blu-ray products will be probably expensive in the first times because of low volumes of production, but that will not be a problem very a long time since one envisages already a broad product range relating to Blu-ray (readers, recorders, engravers, media, etc) what normally will help to lower the production costs in general because volumes of production will be increased. Thus, as soon as the series production begins from the components for the Blu-ray products, one expects that the prices drop quickly. But right now, the principal film studios strongly support the Blu-ray format because it is said successor of format DVD of today, but two formats (Blu-ray and DVD) will surely cohabit for a long time still while waiting for that the TVHD are more widespread.

Which tourist information in the pocket of the traveller and when

New technologies invaded our daily life causing of new practices and the novel modes of consumption and became today an integral part in research of the traveller the least expensive to find the plane ticket, the best quality ratio/price of a hotel or the formula of holidays best adapted to its desires.

The Mobile Tourism allows in real-time receive and consult tourist information thanks to the mobile phones. It became a formidable and essential tool for the holiday makers in search of exits and good plans.

It is also a true revolution in terms of communication and marketing of the tourist offers. The latter do not influence not only the traveller but also the suppliers, the intermediaries and the technological companies.

All the sectors of tourism are concerned with these applications: the excursion, the winter sports, cruisings … They make it possible to accompany the visitors in the discovery by a place, that the visit free or is accompanied.

Moreover, wireless technologies, Internet and of géo-localization offer today to the actors tourism the ideal environment for the development of offers of service such as the reservations, the hirings and the online payments but also to multiply the possibilities of information: to locate, guide, propose the possibilities of lodging and restoration, but also to take note of other possible, cultural activities or not, and of the event-driven one.

To synthesize, the TIC make it possible to organize unfolding its stay, role formerly only dedicated to the travel agencies, the tourist offices or to the guide-interpreters.

Blu-ray: the audio-visual one in details époustouflants… and 3D!

The fight between HD DVD and Blu-ray extremely made think of the combat between Betamax and VHS in the Eighties. Everyone was of agreement that Betamax had all the advantages on the quality of the recordings. Unfortunately for Betamax, VHS was cheaper and, moreover, the time of recording was, at the beginning, longer: 60 minutes against 180 maximum minutes.
Although the manufacturers who supported Betamax offered a solution to this problem, they arrived too late. VHS was already the favourite of the large studios of Hollywood productions. Moreover, the legend wants that VHS allowed the pornographic recordings whereas the creator of Betamax pushed back the pornography of his format.

What is it for the modern fight? Contrary to the battle of the Eighties, which lasted a good decade, that of the support for the high-definition was gained in a few years. On the other hand, some parallels nevertheless are found.

The beginning, in 2006 more or less, HD DVD allowed a better quality than Blu-ray. The old films which one quickly put on the market in Blu-ray were clearly less Nets that their against-shares in HD DVD. The reason was the codec of conversion which makes it possible to compress the enormous quantities of data necessary for the material in high-definition on a disc of 30 gigas.

That employed by HD DVD was thus better. Blu-ray hurried to solve this defect. Contrary to the attempts at Betamax to improve, Blu-ray was able to do it in time. Meanwhile, the team of marketing did not remain inactive and it gradually succeeded in convincing the Hollywood studios to choose its format.
For the consumer it is positive to have this clearness. Just as the readers of DVD at the time, the Blu-ray readers drop gently in price and become accessible, as well as the discs. Together with a television set LCD, plasma or LED with high-definition, the consumers can benefit today from the detail époustouflant in their living room, even in 3D. Technology case to astonish us!

Pile apparatus where with battery?

When it is a question of buying a new apparatus requiring of energy to function, we take into account of many criteria for finally making our choice. It is the case for example when one wants to invest in a new numerical camera, a walkman mp3, but also any wireless device, like a flashlight. The characteristic of these apparatuses is to facilitate the life to us, and to function without needing to be connected permanently. Thus, the greatest question, independently of the characteristics of the object as such, is undoubtedly the following one: piles or battery? Here some brief replies:

Piles: They can appear obsolete, but they still have their followers. Indeed, the piles offer certain undeniable advantages for your electronic devices and portables. The first great advantage of the piles, it is that one can find of it absolutely everywhere in the world, and that they are always similar. Not need for adapter as it would be the case for any apparatus requiring a connection if one leaves on a journey abroad. Then, the piles are small and take only little place in your business: they make it possible to reload your camera, gps or reader mp3 for example anywhere, any time, even in full medium of the night or at the time of weekends far from any energy source. The disadvantage of traditional piles is that is needed, according to the apparatus used and of its consumption in energy, to rather often change them, which can cost rather much if one must repurchase some each time. In this case, better is worth to choose alkaline piles, which will last longer before discharging. But to mitigate this problem, why not invest in a set of rechargeable batteries as well as a charger, who will allow you to reload your piles up to 1000 times before having to repurchase some. While following a system of bearing, it is thus possible to have always with oneself full piles to reload its apparatus in a few seconds.

Batteries: This alternative to the piles knows an increasingly broad passion. An aircraft equipped with a battery indeed often holds the load longer than an apparatus with piles, and takes care directly on sector, or more and more thanks to a port USB, which makes it possible to charge via a computer. The battery apparatuses represent an obstruction minimal but have also the disadvantage to have to be directly in charge on a source of electricity, unless having a battery of replacement. The system of the battery of replacement makes it possible never not to be with course of autonomy, but according to the model, a battery moreover can involve a certain investment. There exist also solutions known as “alternative”, such as for example of the solar chargers (with piles or batteries, sometimes adaptable to both), who allow to reload your apparatuses where that you are, without needing socket-outlet, thanks to solar energy. Although this solution is appropriate for an auxiliary loading, it is however preferable to have another possibility of load for every day.

Why buy its piles, batteries and chargers on Internet?

The answer to this question can appear obvious with those which took for practice to use the Internet for various purchases. Indeed, we are increasingly numerous to order our books, Cd, dvd, and other articles of this type on Internet. But this method of purchase still lets plane the doubt among some, in particular for articles on which one could need information. It is the case for electronics in general, and thus also for the material which makes it possible to charge the latter, which however needs often to be renewed.

Many thus prefers always to go in a specialized store and to profit from the advised councils of a salesman who will be able to switch them. But it is necessary well to acknowledge that it is increasingly difficult to find a salesman really qualified, and rare are those which will let to you leave without anything to buy rather than to sell an article to you which will not be the best for your specific needs. Without speaking about the “good ideas” that certain not very scrupulous salesmen have who will make you buy an additional article under the pretext that “you will not be able to any more you to pass”, whereas you had come with a quite precise idea from what you want … the advantage of the Internet is the approach “zero pressure”. You will not have a physical salesman to help you, but blow, will not have you to muddle you either. Moreover, specialized Internet sites offer from now on increasingly detailed descriptions of their products, research assistants enabling you to find for example the model exact of charger who agrees with your computer, practise prices often much less low than the physical stores and, in the case or a question is always without answer, the customer services of these online shops are increasingly effective, and profit especially trained advisers.

That it acts chargers, batteries or of any other article having milked with electronics, it is important to be able to count on a good guarantee, and the products of this type are sometimes likely to be damaged at the time of the routing. Fortunately, the sale on line is not any more with its stammerings, and the problems involved in the delivery, although being increasingly rare, are regulated today very simply, and any damaged goods are immediately exchanged, whether it is about a charger computer or of a battery conveys. In the same way, the guarantees suggested by the online shops specialized in electronics go today much further that the simple guarantees manufacturer.

And for those which still hesitate to pay an online shopping by chart, will know that the sites posting a waiter made safe for the transactions are very sure, and this type of payment is undoubtedly less dangerous than to walk in the street with money on oneself to pay its new charger for portable in a store of electronics or telephony.

Lastly, to seek a charger or a battery on Internet makes it possible to avoid the nuisance moving for nothing. You can also take time to examine various offers, and to choose the site which offers the best price or the best services for your battery, your charger or even your piles.

Professional fixings and supports for gps and pda

Many trade associations require that one be equipped with a telephone, GPS, PDA or another embarked mobile device. It is not of course possible to carry a telephone to the ear, or to have to handle an apparatus held with the hand when one leads. Thus, for many conveyors, deliverymen, representatives, commercial and many professionals passing much of time at the wheel of a vehicle, it is essential to be able to be reachable constantly, to consult routes, an electronic diary, or to pass a telephone call without necessarily having to stop, which would constitute a true waste of time of course.

The solutions exist, as each one knows, but they are not always as practical and reliable as one could believe. Which is the interest of a support for GPS which one cannot direct and regulate to agree perfectly with the angle of vision of the user? Why have a freehand installation for its telephone if one cannot hear his interlocutor correctly, or be heard oneself even, at the point to have to end up detaching to put the apparatus of its fixing and it at the ear, with all the complications and all the risks that implies?

Each one will be appropriate about it, for this type of product, one cannot be allowed to go at least expensive and to choose the first come system, because all are not worth, and it goes from there from the safety of the drivers and the image of your company. It is thus essential to get its support PDA, support GPS, or attachment unit for smartphone at a professional, who will be able to recommend the ideal type of fixing exactly to you, by taking into account at the same time your vehicle, the mark and the model of your mobile device.

The simplest solution and most interesting is undoubtedly to order its attachment unit conveys, motor bike or utility on Internet, a specialized site and serious. Advantage of such step is before very that the best sites are equipped with an instrument of research, which will be able to recommend adapted fixing to you, according to the models available. There still, it is thus necessary to choose a site of reference, which proposes equipment of mark like BroditProclip and Carcomm.

It can also be interesting to turn to a professional of the supports for mobile devices who will be able to carry out your attachment unit to measure, so that even if your mobile device is not famous brand, or if there does not exist specific system of fastener being appropriate for your vehicle, you will be able to fix your GPS all the same, smartphone or PDA in full safety.

For an additional time-saver, certain professionals even propose to install your attachment unit for mobile device directly in your vehicle. Thus do not hesitate to compare the offers and to benefit from the many promotions suggested on the online shops specialized in the sale of attachment units conveys for mobile devices. You will profit thus from a fast delivery, a guarantee of quality and certainty of approved, reliable and aesthetic equipment.

The computer is broken down: with which to address itself?

The computer of the student son or family computer PC functions since months and the whole family is satisfied. But one beautiful day, the computer “plants”. Then animated good will, each family member tries to solve the problem. Each one heard, at the office, the school, faculty or during discussions between friends who there exists a manner of repairing the computer. After several attempts and some arguments the recalcitrant computer does not want to start again. Then how to make?

The first reflex consists in getting information near the salesman working in the store in which you bought the computer. But this track is limited insofar as the salesmen are seldom data processing specialists. Then try to call the hotline of the manufacturer. Good courage! A little like the hotline the telephone operators, it is not rare to have patience a few minutes before obtaining a conversation with a person who alas does not know any more than you on the problem.

It any more but does not remain you to ask for the services of a specialized company in the data-processing breakdown service. The data-processing breakdown service is an activity in full rise, would be this only by the always increasing sales of computer material. It is certain that in the event of material breakdown, it will be necessary to turn over the computer to the store for an exchange or the seat of the manufacturer. But in the event of software breakdown, the break-down mechanic out of computer material will be able to find the answer.

The tariffs of these specialized companies in the data-processing breakdown service are variable. Some propose the fixed price, more running, others practise the system of subscription in certain cases.

Another interesting solution to try to repair your computer material: since it is broken down, to a knowledge, a neighbor or a cybercafé and you connect return on a treating forum of data processing. You will read certainly subjects concerning the same problem that you meet and will undoubtedly obtain the answer to lower costs.

But if you hope one day to use the services of specialized companies in the breakdown service of computer material, take care to note their addresses before breaking down!

Is Pourqoui the virtualisation of the waiters important?

The lines of business are computerized more and more. We observe a multiplication of the waiters. Waiters which increasingly powerful and under-are often exploited.
This growing number of equipment bring material and financial constraints.

These constraints are in opposition with the present needs for the companies: reduction of the data-processing costs, prevention of the material breakdowns, multiplication of the equipment and easy management of the equipment.

The various evolutions of data processing lead inevitably to modes or tendencies on the management of data processing by the Directions of the Information systems.

It is with a minimum of technical terms that I will present this technology to you, will evoke his uses, his advantages and his rare disadvantages, to finish with a real example quantified on the virtualisation of the waiters of site YAH00 Groupes in 2006.

Advantages of the virtualisation

First of all, Virtualisation makes it possible to optimize the use of the resources. Then, these technologies also make it possible to realize savings on the material thanks to the mutualisation. In the event of need of more than resources, a virtual machine can very simply be moved on a waiter less requested or more powerful. Finally the installation, the deployment and the migration can be facilitated thanks to the use of the virtual machines.

*La mutualisation
The mutualisation is the action to gather several virtual machines on a physical waiter, one leaves the diagram: “An application = a physical waiter”.

This technique makes it possible to reduce the number of physical resources necessary, to simplify the infrastructure network and thus to reduce the budget of investment.

*Réductions of the data-processing costs

The number of waiters and the quantity of computer material necessary in the data center will be reduced. That results in a reduction in the real expenses, requirements in power supply and air-conditioning, involving a clear reduction of the data-processing operating costs.

Following the mutualisation of the resources, it is possible to consider the concentration of the equipment. Indeed, if we have less physical equipment, we need less place to store them. We can then gather them in a single room whereas they were placed in several before. It is necessary to keep in mind that a computer room worthy of this name is a concentrate of technology (Breakdown by the false-floor, protection fire, access control, antiseismic protection).

Daily applications of the virtualisation

For recall, a virtual machine is only one file carried out by an application. On the basis of this principle, nothing is easier than to safeguard it, on various supports, to modify it or to restore it.

*Environnement of test and deployment

It is indeed another asset of the virtualisation. During tests of parameter settings, nothing is easy any more, in some clicks, than to return in an initial state of the virtual machine.
Thus, the teams of validation can devote more time to the phase of test or reproduce the environment of production of their customer.
Easy administration: the various tools of virtualisation are easy to take in hand.

*Security

The virtual waiters “are completely isolated” from the waiter host and other virtual machines. It is thus very easy to delegate tasks of administration on one or more waiters while avoiding an direct access with the physical machine.

* Availability of the resources

We saw previously that a physical machine supports several virtual machines. It is thus natural to wonder about the impact of the stop of a waiter host.
Indeed, if the physical machine breaks down, it is not any more one, but several waiters which stop with more or less important consequences for the data-processing production.
In order to avoid all nuisances of this kind, there exist two solutions:

- The distribution of load
The distribution of load is not resulting from the virtualisation, but functions according to a similar mode, starting from a specialized case.
Let us suppose that the production of the company rests on 2 critical applications laying out each of two waiters. The principle is of course to use a waiter in help in the event of breakdown of the other, but also to distribute the load of a waiter on the other with for objective the maintenance of response time correct and sufficient to ensure the production.
We thus have below 4 physical waiters, which as we saw previously are overall unoccupied (average rate of occupation of the processor: 15%).

By virtualisant these waiters, it is thus possible to plan to set out again the load on 2 or 3 waiters physique.

- The automatic recovery on incident
Virtualisation serves also the prevention of the material breakdowns and the improvement of the recovery plan of activity. Indeed, the virtual equipment being a whole of files, it is easy to safeguard them. In the event of material problem on their waiter host, the files safeguarded before could very quickly be restored on one on another host. It will then be enough to start the virtual machine to take again the activity.

Installation (When? and How?)

1. To estimate its needs for storage

Despite everything the advantages had by the virtualisation, it is necessary to keep in mind that the storage of the images of the virtual machines represents a considerable disk space.
Moreover, let us not forget that it is also necessary to safeguard according to a rate/rhythm defines by 'system administrator, the databases and other applications supported by the virtual machines.
MATERIELTU
The acquisition of a storage unit network (NAS: Surface of network storage: data-processing equipment connected to the network providing the function of data storage) must thus accompany the virtualisation to respect an effective policy of safeguard.

2. To have a powerful network

As evoked in the preceding chapter, it is imperative to have a consequent storage. Now, it is necessary to adapt its architecture network to the quantity of data likely to forward on this network.
At the time of the restoration of an image of virtual machine, the network must be able to continue to offer same quality of service to all the applications.

Indeed, the installation of Virtualisation can requires a recasting of the already existing and pleasing architecture of new security issues. These technologies require additional competences. If there is only one virtual machine per physical machine, the losses of resources compared to the initial system are considerable.

Estimate of the direct and indirect costs of data-processing architecture before and after virtualisation: For YAHOO! (in 2006)
of + 1.5Millions to +700.000$.

In general, a user changes his hard drive every 5 years, unfortunately it arrives sometimes that the hard drive which contains our invaluable (or not) given ends up weakening before this period. Most of the time, of the “extreme conditions” of use (too high temperature, too important activity, no maintenance carried out) are quoted like primary reason of failure.

The study undertaken by Google gives us more details on this subject. Presented at the time of a conference on “the files and technologies of storage”, the report/ratio of the firm with great G concludes that an hard drive can return the heart for reasons as various as varied.
At present, Google would count more than 450.000 waiters, the majority would use hard drives “general public” with capacities going from 80 to 400 Go. The study of Google would have related to more than 100.000 discs which entered under operation during or little time after 2001. These discs 5400 or 7200 turns/minute would come “from various large manufacturers of discs and would gather new principal models”.

To make a its study, Google would have consulted the whole of “vital” information which it would obtain from its waiters. Frequently updated information, at a few minutes of interval. In this field, one can in particular quote: temperatures, levels of activities or parameters SMART (Coil-Monitoring Analysis and Technology Reporting), often used to detect/prevent problems to come on an hard drive.
Google noticed, without surprise, that the rate of hard drive weakening with tendency to increase as the disc ages. During the first year of their actuation, 1.7% of the 100.000 hard drives used by Google would have being thus replaced. This percentage would have passed to 8% during the second year and 8,6% during the third year. Once entered its fourth year of life, Google affirms that the remaining lifespan of the hard drive “is more influenced by the model/mark that by its age”.

The problem of error of “subjacent task” of closing is often related to the defective blocks or sectors.

From which do they come?
It is about a all the more frequent manufacturing defect as the capacity of the discs reaches phenomenal proportions today.
A partition of disc is a volume. This volume is made up itself of several circular plates themselves segmented in blocks which one calls the sectors.

How much blocks is there on an hard drive or a volume?
A current disc contains almost 2.000.000 of blocks by giga is almost 2.000.000.000 (two billion) of blocks for a disc of 1 terabyte.

Surfaces of storage in full evolution, 1998 and in the same volume, an hard drive of 500 Mo sheltered only one unhappy million blocks.

For that it is necessary to add the collapse of the costs: in 1998 a disc of 500 Mo cost in francs the equivalent of 280€, whereas one finds today and at all the discounters, of the discs of 1 To for 115€, which makes fall the price the gigabyte of 560€ to 0,12€; not badly in 10 years!
If we applaud the technical performance, reliability did not follow the same course alas…
With a dimension reduced in such proportions. The sectors weakened, and their number in permanent growth increases the risk to find the defective ones.

A bad block, it is what?
A defective block is a sector (512 bytes) on which magnetizing (the writing) is not done correctly, therefore on which the files can neither be written, nor read correctly.

Consequences of the bad blocks:
Apart from the risks of loss of data, more they are numerous and more the disc is delicate to repair, a disc which has some much is trailed literally, the more so as their site is important, if they is at the head of partition it is straightforwardly catastrophic, because one can have split a Bitmap volume of which part of the data was moved on the zone of reserve…

How to prevent this kind of incident:
The manufacturers of discs advise to leave permanently at least 10 to 15% of free.
Carry out a regular maintenance of your disc.
To make safeguards on an external disc, dvd, you can also create an image disc of your system which will enable you to find your configuration if you must change discs.

Setting does not keep for the treatment of your disc with Filevault and the blocks defective.
Filevault encrypte your account user in only one and single file.
If your encrypté account occupies only one and single block on several million blocks, your file-image will be incomplete, the encryptée image of your account will be irremediably damaged without any hope to even recover though it is, not the least file!

Conclusion
The defective blocks are a big problem. Admittedly the Apple system is able of in réallouer much, but if the number has suddenly become extensive, Mac is not able any more to manage them and the restarting is often not possible and the hard drive is changed.

It is what the bios of a computer?

The BIOS (“BASIC Input/Output System” translate “elementary Management system of the inputs/outputs”) is an essential component of the computer, allowing the control of the material elements.

It is about a small software of which a part is in a ROMANIAN (read-only memory, i.e. a memory which cannot be modified), and another part is in a EEPROM (modifiable memory by electric impulses, from where the flasher term to indicate the action to modify the EEPROM).

The POST When the system is put undervoltage or restarted (Reset), the BIOS makes an inventory of the material present in the computer and carries out a test (called POST, for “Power one Self Test”) in order to check its good performance: To carry out a test of processor (CPU), To check the BIOS, To check the configuration of the CMOS, To initialize the timer (the clock interns), Initialiser controller DMA, Vérifier the random access memory and the memory hiding place, Installer all the functions of the BIOS, to check all the configurations (keyboard, diskettes, hard drives…).

If ever the POST meets an error, it will try to continue the starting of the computer. However if the error is serious, the BIOS will stop the system and: To post a message with the screen if possible (the material of posting still not being inevitably initialized or being able to be failing), to emit an aural signal, in the form of a sequence of beeps (English beeps) making it possible to diagnose the origin of the breakdown, to send a code (called code POST) on the port series of the computer, being able to be recovered using a specific material of diagnosis, If all is correct, the BIOS will generally emit a short beep, announcing that there is no error. Thus a long beep, follow-up of two short beeps indicates an error due to the video peripherals (graphics card).

In this case it is necessary to try to plug in the video chart correctly to even change some. Any other beep indicates an error due to the memory.

To choose its cartridges or toners well

For speaking about the choice about the cartridges or toners, it is undoubtedly necessary to speak about the choice of the printer. Indeed, it is necessary to determine the real needs as regards impression before investing in an apparatus, and the type of impression is one of the most determining factors in the final choice.

In fact, printers with cartridges, known as with jet of ink, and printers functioning thanks to one to thunder, namely the printers laser, have functions integrating advantages and disadvantages, the whole being to know what corresponds to you best.

Thus, it is necessary to wonder what is a priori most important for you. That it is about the print speed, i.e. number of pages which can be printed at the minute, of the format on which you want to print, of the quality of returned: do you wish for example to be able to print photographs? Do you need a printer multifunction? Do you want to print documents from time to time or you will make an intensive use of your printer? All these questions have their importance, and all these points are to be taken into account because, once the bought printer, it will regularly be necessary to invest in the “consumable ones”, which are not other than the toners or the toners. The two solutions are very good, they do not relate to simply the same types of use.

For a company, for example, which prints hundreds of pages per day, it will undoubtedly be more interesting to choose a laser writer, often faster than the ink jet printers of ink. The quality of the impression is relatively good, sometimes even excellent according to the model, but it should well be recognized that such machines are very often more expensive with the purchase. They however make it possible to realize unquestionable savings on the long run, and their speed can also contribute, in any case in the professional context, to save money.

Contrary, it will undoubtedly be more economic for the private individuals to invest in an ink jet printer of ink, especially if the impressions are very few. The system of the ink jet printer of ink makes it possible to obtain, much less quickly than with the laser, certainly, an exceptional quality in particular for the impression of photographs.

It is also necessary to consider the price of consumable according to the type of printer chosen, but also of its mark, its model, etc

It is thus important to choose well at the beginning its model of printer, in order to avoid bad surprise at the time of the purchase of these consumable. It can also be interesting to check if the model of cartridges necessary available in cartridges is recycled or compatible, which often makes it possible to realize rather important savings.

Lastly, it is important to choose its retailer of consumable well, and most interesting is often to call upon a specialist, of which much has an online shop, which makes it possible to find quickly what one seeks and to compare the prices effectively and to make very good deals, in particular thanks to the grouped offers, fresh in free ports beyond of a certain sum of purchases and other promotions.

To choose its compatible toner?

The compatible toner is the most economic means to get ink with low costs and for a quality often equal to that of the manufacturers.

On average, the price of a compatible toner is approximately 30% less expensive. The recorded fall can even go up to 50% lower always for suppliers of serious compatible ink. These offers particularly enticing are locatable easily for example, in end of ray and at the head of gondole of large surfaces.

For choosing the cartridge well that you need, take in hand the technical documentation of your printer and retain well the reference of your apparatus, marks and model not to note that you made the bad choice once return to you.

Several purchasing possibilities are offered then to you according to your spending patterns or your sensitivity to publicity. For a warned Net surfer, it will be enough to be subscribed with a newsletter of a supplier to know in real-time the promotional offers practised by this retailer. If you are in favour of “I want to see what I buy”, the solution is to return to you in the large signs and to check visu compatibility.

Once in front of the ray of the compatible toners, read packing in order to find the mark and the precise model of your printer. If you do not find your references, there is extremely to bet that your printer is old and is not referred any more in the manufacturers of compatible. In this case, the solution is to question the salesman of the shop, and if not to go to visit the Web site of the original manufacturer of your printer and to put the question by email.
In the urgency if you are with court of ink, it can also frequently happen that the store does not have in stock the desired cartridge any more. If you live in a big city, it is easy to visit several shops in the search of your compatible toner, but if you are excentré, the problem becomes acute. In all the cases, it is very strongly advised to have cartridges in stock, but not too either because ink being a perishable matter, your cartridges can be very well found out-of-date. Consult well the packing of the toner.

The purchase of your compatible toner on an Internet site offers, most of the time, more flexibility in research of your model and the advance of your order.
Privilege the Internet sites which require the mark of your printer and the model.
Even if your machine is old, the Web site must be able to refer your printer. In this case, compatibility is automatic with your model, and it any more but does not remain you to carry out the payment. There too, check that the port is included/understood and if it is offered only starting from one certain amount, not to forget to add it to your total expenditure. The delivery will intervene in general under 48 to 72 H for products in stock

The specialized companies in the manufacture of toner compatible are Pelikan, Armor, Emstar, Certtone and IT-Works. One can on sale find this type of cartridge on Internet sites specialized on sale of and office supplies toners.
Privilege the sites of sale in line of compatible cartridges which give the mark of the sold compatible cartridge.
Attention also with the promotional offers which would sell several cartridges to you, black and a color, and you have the utility only for only one.

How to reload its toners?

Progress, it is well. Us days, rare are those which do not have a computer with printer, to print their photographs, taken using a numerical camera or of their cellphone. We can benefit from new technologies for a relatively accessible price, in any case as regards the purchase of the apparatus in question. But to continue to benefit from it, a great number of these little marvels require piles, batteries, peripherals and, in the case of the printers, cartridges. These cartridges, toners, ribbons and other refills of impression, are gathered under the term of consumable. The consumable ones being essential, numerous are the manufacturers who do not hesitate to sell a printer very little expensive, for then requiring exorbitant sums for the toners.

But fortunately, progress exists in all the fields, and of the solutions are profiled from now on to reduce the cost of the consumable ones. Cartridges known as of origin are thus found, those which are manufactured by the manufacturer of the printer to which they correspond, they are also most expensive. But not only. Many specialized retailers propose for example compatible cartridges, which will be appropriate exactly for your model of printer without being produced by a famous brand. These cartridges are thus much less expensive. Then, one can turn to cartridges recycled, which are not other than cartridges of origins which, after to be used first once, are cleaned by professionals and again filled of ink to offer one second life to them. They also offer the advantage of contributing to protect the environment.

Lastly, and it is undoubtedly one of the greatest revolutions as regards consumable printer, it is now possible to recycle oneself its own cartridges, by filling them with a special ink. Even if this process can appear somewhat hazardous, the retailers with this intention propose kits of filling for your cartridges which make an operation of it practically inratable. The principle is simple: you buy bottles of ink of the colors necessary, which will be sold with “injectors”, small syringes being used to fill the cartridge correctly. Are detailed informations generally provided to avoid any … handling error the result? Sometimes you can re-use your cartridges until a score of time, and make exceptional economies, in particular if you print many documents.

However, it always should be checked that ink is compatible with your cartridge, and that the cartridge which you have allows of type of man œ uvre, because a cartridge badly filled could damage your material of impression. Thus do not hesitate to inform you near the retailer of your choice, which will be able to propose to you the solution best adapted to your ink jet printer of ink.

On the other hand, for the toners, one will prefer, to make economies, a good to thunder compatible. Indeed, to recycle oneself one to thunder of impression can be very delicate, complicated, even dangerous. The products used are pulverulent, and the success of such an operation is absolutely not guaranteed. Better is thus worth not to take risks, and to be satisfied one to thunder ready to install.

A regular maintenance avoids the degradation of your equipment

In an hard drive, one finds plates rigid in rotation. Each plate consists of a disc generally made out of aluminium, which has the advantages of being light, easily usinable and nonmagnetic. More recent technologies use glass or the ceramics, which allow surface qualities still better than those of aluminium. The faces of these plates are covered with a magnetic layer, on which the data are stored. These data are written in binary code [0,1] on the disc thanks to a read/write head, small antenna very close to magnetic material. According to the electric flux which crosses this head, it modifies the local magnetic field to write either one 1, or one 0, on the surface of the disc. For reading, it is the same principle which is used, but in the other direction: the local magnetic field generates an electric flux within the head which depends on the value previously written, one can thus read one 1 or one 0.

A typical hard drive contains a central axis around whose the plates turn at a number of constant revolutions. The read/write heads are connected to the same reinforcement which moves on the surface of the plates, with a head by plate. The reinforcement radially moves the heads through the plates while they turn, thus making it possible to reach the totality of their surface.

Associated electronics controls the movement of the reinforcement as well as the rotation of the plates, and carries out the readings and the writings according to the requests emitted by the controller of the disc. The firmwares of the recent hard drives are able to organize the requests so as to minimize the access time to the data, and thus to maximize the performances of the disc.

Why carry out a cleaning disc?

The Nettoyage tool of disc enables you to release from space on your hard drive by seeking on your disc the files which you can remove in full safety.

You can choose to remove certain files or all. Use Nettoyage of disc to carry out the following tasks in order to release from space on your hard drive:
• To remove temporary files Internet.
• To remove the files downloaded programs, for example ActiveX controls and the Java applications which you downloaded on Internet.
• To empty the Basket.
• To remove the temporary Windows files.
• To remove optional the Windows components which you do not use.
• To remove the programs installed which you do not use any more.

Many users do not think of carrying out a cleaning of their hard drive regularly what involves a deceleration of their operating system or its failure.

At the time of an intervention in a customer we found ourselves with U system Windows XP with only 6,6 MO of free space, our customer did not have never to clean her disc, they was necessary for us to intervene in 2 times in order to carry out a complete cleaning of its PC.

The utility cleaning disc lasted more than 3 hours for an hard drive of 40 go and the utility of defragmentation failed 2 times in its procedure. By the continuation it been necessary to repair all the registers and to carry out a complete update of its system and its pilots.
As information, an intervention of maintenance generally proceeds in 1:30.

A regular maintenance avoids the degradation of your equipment.

Technology of LED Backlight Television

TV manufacturers can use an LED backlight instead of the Cold Cathode Fluorescent Lamps (LCD-CCFL) used in most LCD televisions. LCD-based televisions described as ‘LED TVs’ are different from self-illuminating Organic light-emitting diode (OLED), OEL or AMOLED display technologies. In the UK, the ASA (Advertising Standards Authority) has made it clear in prior correspondence that it does not object to the use of the term ‘LED TV’, but does require it to be clarified in any advertising. There are several methods of backlighting an LCD panel using LEDs including the use of either White or RGB (Red, Green and Blue) LED arrays positioned behind the panel; and Edge-LED lighting, which uses white LEDs arranged around the inside frame of the TV along with a light diffusion panel to spread the light evenly behind the LCD panel.
Compared to regular CCFL backlighting, an LED backlight provides higher brightness and improved color gamut. However advancements in CCFL technology mean wide color gamuts and lower power consumption are also possible. Cost is the principal barrier to wide use of LED backlighting on LCD televisions.
The variations of LED backlighting do offer different benefits. The first commercial LED backlit LCD TV was the Sony Qualia 005 (introduced in 2004) and featured RGB LED arrays to produce a color gamut around twice that of a conventional CCFL LCD television. This was possible because the combined light output from red, green and blue LEDs produces a more pure white light than is possible with a single white light LED. RGB LED technology continues to be used on selected Sony BRAVIA LCD models, with the addition of ‘local dimming’ which enables excellent on-screen contrast through selectively turning off the LEDs behind dark parts of a picture frame.
Edge LED lighting was first introduced by Sony (September 2008) on the 40 inch BRAVIA KLV-40ZX1M (referred to as the ZX1 in Europe). The principal benefit of Edge-LED lighting for LCD televisions is the ability to build thinner housings (the BRAVIA KLV-40ZX1M is as thin as 9.9mm). Others have also introduced Edge-LED lit LCD televisions with extremely thin housings.
LED-backlit LCD TVs are considered a more sustainable choice, with a longer life and better energy efficiency than plasmas and conventional LCD TVs. Unlike CCFL backlights, LEDs also use no mercury in their manufacture. However, other elements such as gallium and arsenic are used in the manufacture of the LED emitters themselves, meaning there is some debate over whether they are a significantly better long term solution to the problem of TV disposal.
Because LEDs are able to be switched on and off more quickly than CCFL displays and can offer a higher light output, it is theoretically possible to offer very high contrast ratios. They can produce deep blacks (LEDs off) and a high brightness (LEDs on). However, measurements made from pure black and pure white outputs are complicated by Edge-LED lighting not allowing these outputs to be reproduced simultaneously on-screen.
In September 2009 Nanoco Group announced that it has signed a joint development agreement with a major Japanese electronics company under which it will design and develop quantum dots for LED Backlights in LCD televisions. Quantum dots are valued for displays, because they emit light in very specific gaussian distributions. This can result in a display that more accurately renders the colors than the human eye can perceive.

Installing Linux (Tough Article)

Initially, a note about the reinstalments. With Debian, it is very rare to have to reinstall its system completely. The most common cause is undoubtedly a mechanical failure of the hard drive.

Many operating systems require a complete installation when critical failures occur or when one makes an update of the system. And even if it is not necessary to entirely remake an installation, the programs which you use must be reinstalled to function correctly.

With Debian GNU/Linux, it is much more probable than your OS can be repaired when the things turn badly, and not replaced. The updates never require a complete installation; you can always do them starting from the existing system. The programs are almost always compatible with the successive versions of the system. When the new version of a program requires other software, the system of packing makes so that all the software requirements are listed and installed. Many efforts were deployed to avoid the need for a reinstalment: it is the last option! And the fitter is not designed to make an installation on an existing system.

Here the stages which compose the process of installation:

To safeguard all the data or documents of the hard drive on which the installation will be made;
To gather information concerning the computer, as well as documentation necessary;
To prepare free space on the hard drive;
To download the fitter and all pilots necessary to the computer (when one does not use the cédéroms Debian);

To prepare the bands, the diskettes or keys USB for starting, or to install the files of starting - the users of the cédéroms Debian can start from one of the cédéroms;
To start the fitter;
To choose a language;
To set up connection Ethernet network, if necessary;
To create and assemble the partitions on which Debian will be installed;
To look at the automatic process of remote loading/installation/basic system requirements;
To install a bootstrap routine which can start Debian GNU/Linux or another system;
To charge the new system for the first time and to make the first adjustments;
To install at will other software (tasks or packages).
To know the packages which are implied in each stage can help with the resolution of the problems which can occur during the installation. Here main actors of this part:

The Debian fitter is the principal subject of this handbook. He detects the material and charges the pilots necessary, he sets up network connection with dhcp-customer and he installs the packages of the basic system with debootstrap. There are many other minor actors, but the Debian fitter finished his task when you install for the first time the new system.

By charging the new system, bases-config additions the users, regulates the time zone with tzsetup and sets up the system of installation of the packages, with apt-setup. He then proposes to launch tasksel which can install sets of themes units of packages, or aptitude which makes it possible to choose the packages individually.

When the work of the fitter is completed, before the first loading of the system, you have only one minimal system with line of order. The graphical interface which posts windows on your screen is installed only if you asked it with tasksel or aptitude. Its installation is optional because much of Debian systems are waiters which do not need really an graphical interface to be operational.

The fitter does not take charges system X with it. His installation and the dependent problems are not spring of this handbook.

Why carry out its updates!

Many data-processing users took the bad habits not to carry out their updates varied for reasons.

An update, often shortened in MAJ or MàJ, is the action which consists in putting “up to date”, or “on level”, computer tools, a service or a service while downloading, a new software corrective measure.
The English term for a “update” is update. An update is used to improve the output, the effectiveness or the service of a service or a product, and sometimes to correct the bugs of a given program.

The updates exist as well on Apple and Windows and improve the stability of your operating system.

Microsoft has just proposed with the remote loading Service Pack 2 of Windows Vista. For those which are unaware of it, a Service Pack is a whole of corrective measures intended for a system, sometimes decorated - as here - new functions. Service Pack 2 takes again all the corrective measures appeared since Service Pack 1 (but initially the installation of this last requires, contrary to Service Pack of Windows XP) and integrates also Feature Pack for Wireless (which deal with Bluetooth 2.1) and Feature Pack for Storage (with the engraving of Blu-ray integrated into the system).

Service Pack 2 is available for systems 32 and 64 bits, but only (for the moment) in direct remote loading and not in update since Windows Update. Let us note in addition that Service Pack 2 had been already accessible for a few weeks, but only into certain users) and that it integrates a series of corrective measures, but also (in bulk) Windows Live Search 4.0, the support of Via Nano in 64 bits, the improvements of the assumption of responsibility of Wi-Fi, etc

Service Pack 2 is available for Windows Vista, but also for Windows Server 2008, during professional of the system.
The update Mac OS X 10.5.7 is recommended for Mac OS X v10.5 Leopard. It includes/understands the total improvements of the operating system, offering to your Mac an improved stability, compatibility and a safety.

By prudence, it is advised to carry out a safeguard of your disc in order to avoid any problem at the time of the settings systems days.
In the case of an update of microsoftware, where it is a question of reprogramming a memory, one speaks sometimes about flashage, in particular at the time of updates of the bios of a mother chart of a computer.

The new update of Mac OS X 10.6.5 should manage ExFAT

Mac OS X 10.6.5 should manage a new filesystem: exFAT. This format was conceived in particular for the Flash memories. It is used more and more by the manufacturers of cameras (Canon, Nikon, Sony to quote only some of them).

exFAT (Extended File Allowance Counts) is a filesystem conceived particularly for the memories flash and the memory supports external (hard drives and assimilated) introduced into Windows CE 6.0.
The advantages compared to various formats FAT are:
▪ the theoretical limit of the size of the files is of 264 bytes (16 Eio), to compare with the 232 (4 Gio) of the FAT32;
▪ support of larger volumes whereas FAT32 was limited to volumes
▪ performance of the allowance of free space improved thanks to the introduction of bitmap of free space, left software chart of free space as there was a chart of the space occupied by the files, this making it possible to more easily find a free space according to the size of the files to be written and also a faster obliteration this those;
▪ support for more than 216 files per repertory;
▪ support of the Access Control List;
▪ support of transaction-safe FAT (TFAT) file system or filesystem with transactions (modifications) protected of the table of allowance of the files (optional functionality introduced into WinCE). In short, metadata of the TFAT ▪ possibility of storing specific parameters OEM in the metadata;
▪ use of checksums of the file names (name hashes) for a faster checking of those.

In fact, this filesystem is managed right now by certain versions of Mac OS X 10.6.4, in particular that delivered with the last iMac. The next minor update of Mac OS X will generalize this assumption of responsibility.

ExFAT takes all its interest with memory cards of the type SDXC, which can have a theoretical maximum capacity of 2 To. These last had evil to put up with some limiting theoretical of the FAT32.

Even if the things are not very clear on this subject - considering the return of certain users - it seems that the last iMac and Mac Mini are equipped with a compatible card reader SDXC (to also read: Mini Mac has a reader SDXC).

At all events, you will be able to always turn you towards a card reader who manages this standard.

Service Pack 1 of Windows Vista adds the support exFAT1. The support of exFAT is also possible under Windows XP SP2 and SP3 thanks to update KB9557042. The support of exFAT is also integrated into Windows 7.
It was really time that Apple proposes ExFAT because the use of memory flash is increasingly current.

Apple iPad: delayed in France, already on PriceMinister!

Whereas the American consumers watch for the arrival of the iPad 3G which will be officially available on Friday April 30, the European fans of the mark to apple will have to wait to be able to put the hand on the first WiFi specimens which will reach the old continent at the end of May.

The main reason evoked to justify such a delay is the “particularly keen demand” of the tactile shelf on the American interior market (500.000 apparatuses sold since April 3). An argument which resembles a string marketing intended to rather cause the passion with international than with an attempt at serious explanation.

Many rumours floated on the delays with repetition of the iPad, between problem of design (the iPad combines elements provided by South Korean Samsung, Japanese Toshiba, American Broadcom and by hongkongais Amperex Technology, on a level of complexity exceeding by far that of the iPhone*), difficulties of production (the factory Foxconn de Longhua in China where the iPad are produced whole world had problems with the imposed production paces **), but to deprive Apple fan Europeans under pretext of initially want to satisfy the American domestic demand does not correspond so that one can wait on behalf of a company like Apple.

The firm of Cupertino thus created an in-draught in which many retailers were engulfed, and one found the iPad in China thus the week even of his American exit, whereas the exit in this country was not validated yet by Apple and that no support is envisaged ***. In France, Apple Fans will be able to turn to the platforms of sale on line: iPad WIFI 16 go, iPad WIFI 32 go and iPad WIFI 64 go are sleep and already available to the sale for the impatiens which could not endure an additional carryforward of exit.

WOPAD WR701 is a shelf which starts with good to be sold throughout the world, you were numerous to require this complete test of the shelf of us. What does it bring moreover compared to the aPad or Haipad? Already a capacitive screen Multi-Touch as on the iPad. With such an argument, much will change opinion about the Chinese Android shelves especially that the price remained contained.

General characteristics:
The WOPAD is the tactile shelf that much D `between us waited. Finally a shelf which raises the level of quality of the Chinese shelves. Initially, perceived quality is definitely higher than what one with the practice to see, then the capacitive screen brings a true comfort of use.

The screen: 8/10
The screen is one 7 inches capacitive Multi-touch which has a resolution of 480x600. This screen is the best screen by far than we tested on a Chinese shelf, a pleasure to use. Luminous, precise and it is also the best screen to write or make drawings. The striking of a text is faster and more precise than with other screens.

The processor: 4/10
If the screen has charm us, the processor, Rockchips 2818 (AMR926Ej-S REV5 v5l) on the other hand, disappointed us. Given rhythm into 600MHZ, it integrates a DPS for video decompression, but not of GPU for acceleration 3D.

Design and design: 8/10
WoPAD is a beautiful shelf finished well except for the 3 buttons on the top of the shelf which makes a little light. The aluminium hull reinforces the image of quality, it makes solid and the weight of the unit (373 G) reinforces this effect. The shelf has only one Menu button and Home, volume is fortunately accessible by tactile buttons in the application from video reading and music.

With this aluminium hull, the capacitive screen and this level of completion, we are far from thinking, that we deal with shelf only costing. less than 180 euros.

One regrets: The choice of the processor which is by example incompatible with certain plays, in particular Angry Bird. The shelf does not have webcam either. To see the vidéos Youtube, it is necessary to pass by an application of the TubeMate type (available free on Android Market) which downloads initially it video on the shelf to be able to view it.

One likes: Design of the shelf, aluminium completion, the capacitive screen very pleasant to use and very precis, good autonomy.

Conclusion: WoPad is a good shelf for the multi-media one, the Internet, with the proviso of not needing the Flash 10.1. But it is also a very good shelf to write. Thanks to its capacitive screen, this shelf has at the same time the most precise keyboard and of fastest than we tested. It functions very well with plays like: Alpine Board, Ninja Rush, Eagle Nest, Doodle Jump, Rope cut, Air Control…
