Apple's Gatekeeper: better security or threat to our freedoms?

Announced yesterday Gatekeeper is a new feature of the future Mac OS X 10.8, Mountain Lion. A tool designed for the safety of users, but could also be another step towards a limitation of freedoms

In 2007, Mac OS X gave birth to the iPhone OS, now known as IOS. Last summer, the release of Lion, Mac OS X 10.7, has established a milestone in the history of Apple's operating system. The time had come for the younger, to rebound a bit of its glory and its functions on its predecessor.
A process that has accelerated with the announcement yesterday of Mountain Lion, ie Mac OS X 10.8. One might procrastinate on the crisis of innovation that affects conventional operating systems, which now seem to focus only on mobility: think Metro Interface for Windows 8, for example. But this is not our purpose. After all, no matter where does innovation as it allows a more enjoyable and simplified use and protects the user ...
Brave new world
Yet the pleasure of the controversy, anticipation, much as a hint of paranoia, lead us to worry about discovering the gatekeeper function ... Is it not, under cover of usability, integration and enhanced security, one step closer to the gilded cage that seems to be the model of post-PC? A world born of the dark hours spent in hair pulling, in the 90s, before computers unstable and frustrating. A world where the user certain freedoms to sacrifice user experience smoother, more enjoyable, but more limited.

Gatekeeper, three settings between freedom and security

After the introduction of the Mac App Store in Lion, Apple continues to take up the market for software distribution on Mac OS X by introducing Gatekeeper. A security tool that can, depending on the settings you have chosen, not letting you download the applications from the Mac App Store.

Three options are available in Gatekeeper settings:

- The ability to install whatever you want freely (it is disabled in this case?)

- To install only the applications through the Mac App Store or digitally signed by an Apple developer ID,

- Finally the only use the Mac App Store.

To reassure, Apple says it is possible "to temporarily bypass your settings, by clicking and pressing the Ctrl key, and install any application at any time. Gatekeeper allows you total freedom. "

Perchance to dream ...

What would reassure us - if it is a matter of offering the choice between freedom and security - is that a Gatekeeper makes its appearance in IOS. One could then choose applications from the App Store or from other blinds, less secure, but less controlled

Safety goodwill
According to Apple, Gatekeeper is another "maximum safety for your Mac." This is also another step closer to the market for software distribution on Mac OS X from what has been invented, with the success it is, for the iPhone. A kiosk download single only gateway for new applications approved. This has its advantages, the peace of mind, ease of installation and update, but this is not necessarily guaranteed to be protected. The latest twists in the case Path is evidence that the application control is not the ideal solution we hoped. It avoids possibly malware, thanks to the validation of applications, but does not prevent the theft of what is precious to us, beyond the safety of our devices, our personal data.
Therefore, Gatekeeper offering the same model, one can imagine that the door will not necessarily be very careful or at least that its opening will be subject to the whim of Apple and not the vigilance of users. And when one is surrounded by impassable barriers to protect themselves from the outside, but outside the crossing anyway, we are left while the lack of freedom, that the prison that it was built .
However, in the near future, the picture painted is not black, it offers more shades of gray. Indeed, one can not say today that Apple will not make choices in Mountain Lion (see box.

Messages, replacing it with iChat, will be integrated with Mac OS and IOS.
think differently
Unfortunately, given the merger forced march between IOS and Mac OS, how not to fear that sooner or later, the model of the iPhone will require Mac users, no loopholes, if not that of jailbreak? If those who have discovered Apple with the iPhone there are perhaps no complaints, it remains at the bottom of the old macmaniaque, in mind of the user who liked Mac OS X from day one, despite its numerous bugs, because it was vibrating energy of BSD, as a fear. That one day, as on the iPhone - which is all the talent to make us forget thanks to its unparalleled experience that we are not free - we will not have any hands on our Apple computer, it is already difficult or impossible to update yourself physically. In a golden cocoon, then we can do everything smoothly, except to be free, except apply, whenever we want, this famous motto: "Think Different

Elections 2012, way to the Elysee Palace: the improbable game

A small French studio will launch on the market of his presidential campaign simulation. You choose your side and make him win the election

At first glance, the information also appears unlikely that the PS clip for the campaign of Francois Hollande. The fact is that elections in 2012, en route to the Elysium is a game that really exists and will be released on February 24, for download or on CD-Rom. You can play as your favorite candidate or hated it and wear it to the Palace of the Republic or let die during a festival of sausage in a godforsaken corner of rural France. Although this second element of the alternative is not proven.

We think what they like to achieve, talent imitators for the voices of candidates and even programs each, in any case, Eversim, discreet publisher of serious games, including for NATO, and games political simulation, is not in its infancy.
Elections 2012, en route to the Elysee, sold 20 euros, is just the latest in a long line of political games and games at all, since, before Eversim, the team had cut his teeth in studio Silmarils, to whom we owe the excellent Transarctica and Ishar, released in mid 1990.

Ultra HD codec approach

A new video codec is about to be finalized. It should come in 2013 and will cover the images in high definition

You've heard the H264? Not? Yet it became a video codec standard, and it is almost certain that you use daily or almost daily. It is everywhere, in your smartphone, camcorder, camera, your box or your TV receiver.
Developed in 2003 to carry the video stream in high definition (1920 x 1080 pixels), yet it is about to be dethroned by his successor, H265, also called HEVC (for High Efficiency Video Coding). Why yet another codec? Simply to convey the flow of ultra high definition tomorrow: images in 4K (4 megapixel) and even 8K (7680 x 4320 pixels)!

The technological challenge is to achieve a gain in terms of throughput (and thus weight) of 67%! Increasingly clear, this means that a file H265, whose image quality is equivalent to a H264 file will have a flow (or weight in megabytes) of less than 67%
