Einer fehlt noch. Die dritte und längste Variante des Langstreckenflugzeugs Boeing 787 alias Dreamliner ist nun bereit für den Aufbau eines ersten Prototyps. Das ist etwas später als die lange Variante des Airbus A350, von der bisher allerdings nur ein Modell existiert. (Boeing, Flugzeug)

Copyright holders are increasingly demanding that ISPs should block access to pirate sites in order to protect their business.

As the bastion of online piracy The Pirate Bay has become one of the main targets. The site has been blocked in over a dozen countries already, mostly in Europe.

Austria is one of the latest countries to take similar action. After a lengthy legal battle the Commercial Court of Vienna ordered local ISPs to stop subscribers accessing the infamous torrent site.

This week, however, news broke that the court’s decision has had an effect well beyond Austria’s borders. Over the past several days subscribers of the Slovak Internet provider UPC were unable to access the torrent site as well.

Initially it was unclear why the site had been rendered inaccessible as there are no blocking orders against the site locally. However, it soon became apparent that the problems were an unintended consequence of the Austrian censorship efforts.

As it turns out, the Slovak branch of UPC uses a DNS server that’s based in Austria. The IP-address in question, 195.34.133.21, resolves to viedns09.chello.at and points to a datacenter in Vienna.

According to UPC spokesman Jaroslav Kolar the block is not deliberate. He confirmed that it’s the result of the Austrian blockade and the ISP promised to resolve the matter as soon as possible.

“Access to The Pirate Bay through several DNS servers is blocked in the datacenter in Vienna on the basis of a court decision. Since UPC’s DNS server is hosted in the data center, access to some sites may be limited for our users,” Kolar said.

In addition to The Pirate Bay, Austrian ISPs also block access to other “structurally infringing” sites including Isohunt.to and 1337x.to, which broadens the problems.

According to local reports the blockade was lifted for many users yesterday. Those still experiencing issues can bypass UPC’s DNS by switching to a third-party provider such as Google DNS or OpenDNS.

Fixed or not, the news shows the risks and unintended consequences of DNS blocking. The Internet is by definition a global network, so DNS filtering and other forms of censorship can easily carry over to places and sites that shouldn’t be blocked.

Nächstes Jahr plant AMD, alle Grafikkarten zu aktualisieren, vom Low- bis zum High-End-Modell. Die Arctic Islands genannte Familie umfasst neue GPUs im FinFET-Verfahren sowie ältere Grafikchips. (Grafikhardware, AMD)

Die Entwickler des Open-Source-Flugsimulators Flightgear haben leichte organisatorische Probleme. Die Versionen 3.6 und vielleicht sogar 3.8 werden so nicht mehr erscheinen. Stattdessen soll Flightgear fortan mit automatischen, aber trotzdem stabilen Veröffentlichungen zu beziehen sein. (Flugsimulator, Simulationsspiel)

Die WD-Tochter hat die erste 10-TByte-Festplatte mit klassischer PMR-Technik vorgestellt. Das neue Modell arbeitet ohne Dachziegeltechnik, ist jedoch wie gehabt mit Helium statt Luft gefüllt. Dank PMR erreicht die Ultrastar He10 höhere Schreibraten. (Festplatte, Speichermedien)

Changes of various kinds affect FG – it seems this year more than in others. Please read here an overview.

Whatever happened to the 3.6 release?

The simple truth is – it didn’t work out. In the end, the release team had personal constraints, got as far as producing a release candidate but then the efforts stalled. Flightgear is developed by human beings, and sometimes things don’t go the way we’d like them to.

Ideally this should have been communicated earlier – we’re sorry for this, the final decision not to have a 3.6 release was made not so long ago.

At this point, let me take the opportunity to point out the links to the automated builds where you can find the (as we now know rather stable) 3.6 release candidate and an automated nightly build of the FG development version.

The matching aircraft collection can be obtained from the repository following these instructions.

What’s the future?

At this point, we’re not sure whether there will be a regular 3.8 release. Rather, the idea which will be tried is a series of more automated stable releases – about four per year. We hope that this will stretch bug reporting by the general audience from the current one-week period between release candidate and stable (which makes it very hard to act in time) over a wider period, giving us the opportunity to respond better. At the same time, it will decreasing the waiting period for the next stable. Time will tell whether this works better.

In addition, there are multiple changes behind the scenes having to do with the server infrastructure for the FG scenery. Ideally these would not affect the end user, but they take time and effort nevertheless.

Development on the other side did not stop – we keep making FG more interesting.

More impressive weather

The weather system has received an update to simulate lightning strikes during thunderstorms. Each lightning strike will not only trigger a visible bolt, but also (in the Atmospheric Light Scattering (ALS) framework) at night illuminate the clouds in the vicinity for a split second. In addition, the position is registered in FG, allowing aircraft modelers to include ambient thunder sounds with the correct delay – this has for instance been done for the C-172p. Encountering a T-storm at night will be memorable now!

Improvements to aircraft interior rendering

The ALS framework offers a host of new options for aircraft developers, for instance a quick option to render panel backlighting using the so-called implicit lightmap technique, irradiance mappings giving a more faithful impression from where indirect light can fall into the cabin and the option to show reflections of the lit cockpit panels in the windows at night.

A fire-breathing dragon (and other impressive aircraft)

Among the most interesting aircraft to be added to the repository is the dragin. Demonstrating the versatility of FG, this reptile doesn’t fly on magic (like the Santa and his reindeer do, if you know the model…), instead it uses the aerodynamical data from attempts to reconstruct the flight dynamics of a Pterosaur. Let it slowly climb with mighty wingbeats, soar thermals to rise to high altitudes or swoop down in a steep dive – the dragon sure is fun to fly and at the same time instructive.

Substantial updates also have been done for other aircraft which have been under heavy development: Sounds and pre-flight inspection simulation of the C-172p have been improved. The F-14A variant has been added, making use of all recent rendering improvements and including a simulation of compressor stall. Lots of work have also gone into making the F-15 yet better – it now offers C and D variant, operational weapons and radar, detailed sound and simulation of hydraulical, electrical and ECS pressurization system. The Space Shuttle is now well on the way towards a photorealistic 3d cockpit. Substantial work has been done on the avionics, implementing automatic tracking and pointing routines and a realistic procedure to command OMS orbital insertion and de-orbit burns, as well as one of the most sophisticated failure meanagement simulations in FG.

Improvements to scenery rendering

The ALS rendering framework has added effects for improved rendering of runways. Paved runways are now shown with skid-marks whereas unpaved runways can be rendered with a multitude of materials, smoothly blending the runway into the surrounding airport green.

New terrain textures

The regional scenery texture project is progressing substantially – we have new runway textures, dedicated industrial and port textures as well as detailed customized definitions for South America, Africa, the Middle East and South Asia).

Behind the scenes work

Less visually, there is ongoing development on various fronts. The out of window GUI Phi continues to be expanded, providing support e.g. for an instructor station. Using Qt5, a common launcher for all OS is being developed which is expected to ultimately grow into a new in-window GUI option. Finally, the HLA effort aims at utilizing multiple CPUs better by running various subsystems in dedicated threads outside the FG main loop. Currently, only a very limited AI scenario can be run in this mode, but ultimately it is expected to provide improved framerate where poor CPU utilization is the bottleneck.

We hope to be back soon with details on the new release process.
