GCHQ wizards helped prevent Harry Potter book from leaking online

Harry Potter had friends in high places, according to the book’s publisher.

Back in 2005, the fate of Harry Potter was important enough that GCHQ reportedly stepped in to stop a potential leak of the sixth book in the series, Harry Potter and the Half-Blood Prince.

In a radio interview last week, Nigel Newton of Bloomsbury Publishing spoke about how the publisher had employed strong security measures to prevent possible leaks, including guard dogs and a constant security presence at the printing press. Seemingly, the company also had the support of GCHQ, the UK's primary signals intelligence and surveillance agency.

"We fortunately had many allies," Newton said. "GCHQ rang me up and said, 'We've detected an early copy of this book on the Internet.'"

A preview of features for the ‘Barcelona’ release

Join us for a short overview of what the next Flightgear release within the new automated three-month release cycle will bring!

FG goes to Spain

The most visible change to first-time users will be the change of the default airport. For the future, we plan to name every release after the default airport, and thus while the last release has been ‘San Francisco’ (or 2016.1), the next release (2016.2) will go to the beautiful city of Barcelona. Look forward to some impressive scenery and all-new VRF tutorials and suggested flights in the region!

Join us for a short overview of what the next Flightgear release within the new automated three-month release cycle will bring!

FG goes to Spain

The most visible change to first-time users will be the change of the default airport. For the future, we plan to name every release after the default airport, and thus while the last release has been ‘San Francisco’ (or 2016.1), the next release (2016.2) will go to the beautiful city of Barcelona. Look forward to some impressive scenery and all-new VRF tutorials and suggested flights in the region!

Improvements to scenery

Improvements to scenery rendering are being added on all fronts. Supported by shader developments within the Atmospheric Light Scattering (ALS) framework, runways and airport keep can now be rendered in multiple ways in high resolution, and this has been implemented for different regions all across the world – including the new default airport of Barcelona ‘El Prat’.

Places across the world continue to be populated with 3d models, for instance check out the progress on London Heathrow!

See the FG world through an infrared camera

ALS now includes a whole suite of filtering techniques, which allow to select brightness and gamma-correction in-sim (i.e. affecting screen pixel color values visible in screenshots, not only the appearance on the monitor). Part of this filter suite is also a night vision mode and, possibly most exciting, and infrared camera mode. The IR vision shows contrasts based on relative temperatures, with the daily temperature cycles of the environment modeled by the weather system.

New and improved aircraft

The Piper J3 Cub, a long-time resident of the aircraft repository, has now been fitted with a brand-new JSBSim FDM as well as support for high-end effects, including interior shadow mapping. Water takeoff and landing by selecting floats rather than wheels is also being developerd.

The Boeing 757 has been updated with new versions and winglets dependent on selected airline livery. The Extra 500 received multiple upgrades and now includes a simulation of icing effects and a sophisticated failure system.

Behind the scenes changes

Multiple less visible changes have also been introduced:

* the handling of shared scenery models has now been much streamlined – shared models now reside in a single location and are most easily obtained and updated via the in-sim terrasync option. Alternatively a (daily updated) collection can be obtained here.

* FG now supports the generation and application of GPU specific rendering setting profiles. The idea is to make the experience for first-time users more pleasant by pre-setting the rendering quality level to something which leads to a good experience for the selected graphics card.

* Currently, support for pre-defining aircraft states (such as ‘cold and dark’ or ‘in air’ or ‘cruise’) is formalized and introduced, with the aim of routinely allowing in-air initialization of complex aircraft with all systems set correctly.

Stay tuned as we fly towards our next release!

The Ars VR headset showdown—Oculus Rift vs. HTC Vive

Our tale of the tape comparison makes a first-generation recommendation.

In our original reviews of the Oculus Rift and the HTC Vive, we tried very hard to examine these virtual reality systems on their own merits without constant comparisons to the competition. But no product exists in a vacuum. After years of buildup, we’re now faced with two competitive, PC-tethered VR headsets hitting the market right next to each other. Unless you have a spare $1,400 to spend to buy both headsets (or more, if you need to outfit a gaming PC too), you’ll have to pick one or the other if you want virtual reality in your home as soon as possible.

Today, we’ll lay out the major pros and cons of both Oculus and HTC’s VR systems as we see them in order to (hopefully) guide you to the headset that’s right for you. If you’re just planning on scrolling to the bottom for our final verdict, though, here’s a spoiler—we’re not entirely sure you should buy either one just yet.

Headset specs

Other At least 1.5m x 2m of open space for "room-scale" experiences.

Visual similarities

On a pure baseline of technical specs, there’s remarkably little difference in the Rift and Vive. Both sport two 1080x1200 pixel OLED displays (one for each eye) that provide an utterly convincing 3D effect. Both headsets have 90 Hz refresh rates, low-persistence pixel switching, and accurate, low latency head-tracking that quickly updates your apparent VR view as you move and tilt your head in space.

MPA: We’ve Reached a Turning Point on Piracy

The president of the MPAA’s European operation says he believes a turning point has been reached on piracy, with service providers and search engines beginning to understand they all have a role to play. However, it’s also clear that Hollywood is fearful of opening up content across Europe, which in itself could contribute to piracy.

mpaAfter many years of litigation aimed at forcing the world’s largest pirate sites to their knees, the situation on the ground hasn’t changed very much for Hollywood.

Despite having many important legal wins under their belts, almost every single movie is available for immediate download within a few mouse clicks. In fact in some respects the position today is much worse than it was five or even ten years ago.

But while the sites themselves continue largely as before, progress is being made with other players in the Internet ecosystem, a fact recognized by MPA Europe president Stan McCoy as he addressed colleagues in France last week.

“Protecting creativity takes commitment from a whole ecosystem of people and organizations, from theater owners and operators, to technology companies and online service providers, to retailers both large and small, to Internet intermediaries, to law enforcement authorities,” he said.

While relationships with Hollywood are somewhat fragile, Google has indeed made many gestures towards the entertainment industries by helping to make copyright-infringing content harder to find. Payment processors are also doing their part, with Visa, MasterCard and PayPal all trying to stop pirate operations from using their services.

Nevertheless, the overarching message is that Google can always do more and indeed isn’t doing enough. One only has to look at the war of words taking place over the recent Copyright Office DMCA submission process to see that the battle is far from over and more blood is yet to be spilled.

But McCoy appears optimistic and notes that those engaged indirectly in the piracy ecosystem are beginning to come round to Hollywood’s way of thinking that they must together share responsibility to solve the problem.

“I put it to the audience that we may have come to a turning point in our fight against piracy, a point where intermediaries begin to understand that the creative industry does not seek to shy away from its duties and responsibilities – and it really has not – but that instead all players in the ecosystem, which of course includes not only access providers, but also search engines and payment processors amongst others – have a role to play,” said.

If that is the case then Hollywood has probably come a long way. It certainly isn’t going to solve this problem on its own and having powerful allies on board will certainly help its cause. The emphasis these days is indeed on voluntary cooperation such as warning notices schemes but it’s unclear how much further ISPs are prepared to go and whether the notices even have much effect.

But of course one shouldn’t forget the consumers so it’s no surprise that McCoy had something to say about the European Union Intellectual Property Office (EUIPO) study published last week which found that 38% of young people see nothing morally wrong in piracy.

“What is more staggering is that nearly one in four believed that they were doing nothing wrong in accessing digital content from illegal sources for personal use,” McCoy said.

“Clearly it is important that young people understand that making a film, writing a book or recording a song, the amount of time, effort and investment is more than a passion – it is also someone’s livelihood. Let’s remember that 7 million people work in the creative industry in Europe.”

But what that very same survey also found is that the number one reason (58%) for young people to stop using illegal sources would be the availability of affordable content from legal sources. The MPAA is campaigning heavily at the moment claiming it is doing just that, but there are also clear signs that the EU’s plans to outlaw geo-blocking and open up content EU-wide aren’t sitting well with the studios.

In a posting to his LinkedIn page, McCoy likens Europeans’ distrust of genetically modified food to the EU’s plan to tweak copyright law.

“Many Europeans are skeptical of genetic modification when it comes to foods. Should they also be skeptical of genetic modification of … copyright laws?” he asks.

“With its efforts to institute the Digital Single Market and the recent Proposal for a Regulation on Portability, the European Commission seems intent on tinkering with the DNA of the current copyright law. This could have uncertain results for the 7 million people in Europe’s core creative industries, whose livelihoods depend on the copyright system.”

Pointing to a study financed by the EU Commission itself, McCoy suggests there is no need to outlaw geo-blocking, since all but 10% of people are available to find everything they want online.

“The European Commission should rigorously apply its own better regulation guidelines to all copyright proposals, including ensuring that they are backed by strong evidence,” he adds.

“In cases where the evidence isn’t there, then maybe we should stay away from genetically modified rights … and stick with organic.”

Needless to say, not everyone agrees with his stance.
