‘Critical safety issue’ with A380 engines

Friday, December 3, 2010

Australian transport investigators have announced they have identified a “critical safety issue” with engines fitted to the world’s largest passenger airliner. Some Rolls-Royce Trent 900 engines, which power some Airbus A380 “superjumbos”, may be prone to “fatigue cracking”, which could lead to oil leakage and a fire.

The Australian Transport Safety Bureau (ATSB) said they think this was “central to the engine failure” which occurred on a Qantas A380 on November 4, shortly after take-off from Singapore. The airline grounded all six of its fleet of A380s so they could undergo safety checks before they were put back into service. Late last month, Qantas announced the aircraft were safe and began returning them to service.

The ATSB said the manufacturing fault with the Trent 900 engines “could lead to an elevated risk of fatigue crack initiation and growth, oil leakage and potential catastrophic engine failure from a resulting oil fire.” The agency urged Rolls-Royce to “address the safety issue and take actions necessary to ensure the safety of flight operations in transport aircraft equipped with Rolls-Royce Trent 900 series engines.”

Qantas emphasised on Thursday that there was “no immediate risk to flight safety,” but said they would conduct further investigations. A statement from the airline said: “Qantas currently has two A380 aircraft in operational service, following the grounding of the fleet on 4 November. Both A380 aircraft will be inspected at the Qantas Jet Base in Sydney. Inspections will commence this afternoon.” Two other airlines use A380 aircraft with Trent engines, Lufthansa and Singapore Airlines; Singapore Airlines said they were checking the engines of their A380s “on a daily basis”. They said: “The new checks advised by the ATSB will be carried out as quickly as possible.”

The incident in Singapore was embarrassing for Airbus. Aviation journalist Tom Ballantyne said the incident in Singapore was “certainly the most serious incident that the A380 has experienced since it entered operations.” The A380 made its first commercial flight in 2007, and is now in service with several other airlines, including Air France and Emirates. It is the largest commercial passenger airliner in the world, with an 840-passenger maximum capacity, though Qantas’ can carry 450.

Torture proliferates American headlines today: whether its use is defensible in certain contexts and the morality of the practice. Wikinews reporter David Shankbone was curious about torture in American popular culture. This is the first of a two part series examining the BDSM business. This interview focuses on the owners of a dungeon, what they charge, what the clients are like and how they handle their needs.

When Shankbone rings the bell of “HC & Co.” he has no idea what to expect. A BDSM (Bondage Discipline Sadism Masochism) dungeon is a legal enterprise in New York City, and there are more than a few businesses that cater to a clientèle that wants an enema, a spanking, to be dressed like a baby or to wear women’s clothing. Shankbone went to find out what these businesses are like, who runs them, who works at them, and who frequents them. He spent three hours one night in what is considered one of the more upscale establishments in Manhattan, Rebecca’s Hidden Chamber, where according to The Village Voice, “you can take your girlfriend or wife, and have them treated with respect—unless they hope to be treated with something other than respect!”

When Shankbone arrived on the sixth floor of a midtown office building, the elevator opened up to a hallway where a smiling Rebecca greeted him. She is a beautiful forty-ish Long Island mother of three who is dressed in smart black pants and a black turtleneck that reaches up to her blond-streaked hair pulled back in a bushy ponytail. “Are you David Shankbone? We’re so excited to meet you!” she says, and leads him down the hall to a living room area with a sofa, a television playing an action-thriller, an open supply cabinet stocked with enema kits, and her husband Bill sitting at the computer trying to find where the re-release of Blade Runner is playing at the local theater. “I don’t like that movie,” says Rebecca.

Perhaps the most poignant moment came at the end of the night when Shankbone was waiting to be escorted out (to avoid running into a client). Rebecca came into the room and sat on the sofa. “You know, a lot of people out there would like to see me burn for what I do,” she says. Rebecca is a woman who has faced challenges in her life, and dealt with them the best she could given her circumstances. She sees herself as providing a service to people who have needs, no matter how debauched the outside world deems them. They sat talking mutual challenges they have faced and politics (she’s supporting Hillary); Rebecca reflected upon the irony that many of the people who supported the torture at Abu Ghraib would want her closed down. It was in this conversation that Shankbone saw that humanity can be found anywhere, including in places that appear on the surface to cater to the inhumanity some people in our society feel towards themselves, or others.

“The best way to describe it,” says Bill, “is if you had a kink, and you had a wife and you had two kids, and every time you had sex with your wife it just didn’t hit the nail on the head. What would you do about it? How would you handle it? You might go through life feeling unfulfilled. Or you might say, ‘No, my kink is I really need to dress in women’s clothing.’ We’re that outlet. We’re not the evil devil out here, plucking people off the street, keeping them chained up for days on end.”

Below is David Shankbone’s interview with Bill & Rebecca, owners of Rebecca’s Hidden Chamber, a BDSM dungeon.

Dominique Strauss-Kahn, the head of the International Monetary Fund, remained in jail last night after being charged with sexually attacking a chambermaid at a New York City hotel. Strauss-Kahn has agreed to undergo forensic screening before he appears in court, and has vowed to “vigorously” defend himself against the charges, which are likely to create a leadership void at the IMF, disrupt emergency talks over the European debt crisis, and spell the end of his political career.

Strauss-Khan was the favourite candidate for the French presidency, and was expected to announce he would stand against Nicolas Sarkozy this month. But the allegations are expected to destroy the hopes of his supporters, increase infighting among the French left, and leave his political career in tatters. His arrest comes at a critical moment for the IMF, and will likely plunge efforts to stabilise the financial states of struggling eurozone countries into chaos. He was meant to discuss the bailouts of Greece and Portugal with European Union financial officials at a meeting in Brussels this week.

Eswar Shanker Prasad, a professor of international economics at Cornell University, said: “This sordid episode – no matter how it ultimately plays out – will spell the end of Strauss-Kahn as an effective leader of the IMF even if he retains his position, which is highly unlikely.” The IMF, however, insisted it remained “fully functioning and operational.”

Strauss-Kahn was to appear in court in Manhattan yesterday charged with three crimes, including attempted rape, but the hearing has been delayed so he can undergo forensic tests. He was taken into custody by officials while on an Air France passenger plane which was about to take off from John F. Kennedy International Airport for Paris; when detectives approached him in the first class cabin in the aircraft he reportedly asked: “What is this about?” Strauss-Kahn reportedly fled the hotel “in a hurry” after the attack, leaving a number of personal effects behind. “If our officers had been ten minutes later he would have been in the air and on their ^[sic] way to France,” a spokesperson for the New York Police Department said.

The chambermaid reported that she had been sexually assaulted by a man staying in a “luxury suite” at the Sofitel hotel near Times Square. “The maid described being forcibly attacked, locked in the room and sexually assaulted,” the police spokesperson said. Strauss-Kahn came out of the shower naked while the chambermaid was working in the room, tried to pull the woman onto the bed and locked the door, The New York Times reported, quoting police sources. She allegedly fought him off, but he sexually assaulted her again after dragging her to the bathroom, before he locked her in the room; she was reportedly hospitalized afterwards with trauma.

In 2008, a year after becoming the leader of the IMF, Strauss-Kahn was reprimanded by the organization’s board after being involved in an extramarital affair with another senior executive at the bank. More recently, he was pictured driving a luxury car in Paris, causing a media furore over whether his lifestyle fitted with the socialist attitude he claims to represent. But his wife, former television star Anne Sinclair, has dismissed the accusations. She said: “I do not believe for one second the accusations brought against my husband. I have no doubt his innocence will be established.”

NASA has announced that the Space Shuttle Discovery is due to blast off on Tuesday 26 July at 10.39 am EDT.

The news that the 43 hour countdown will be restarted on Saturday comes after the successful resolution of the problems that forced the aborting of the previous launch attempt.

The countdown includes 28 hours of scheduled “hold time” bringing the total time period up to Tuesday.

The launch had been scrubbed previously due to a faulty main fuel tank sensor which was sufferring from electromagnetic interference. Engineers fixed the problem by improving the electrical grounding of the system to reduce interference.

This interview intends to provide some insight into OpenSync, an upcoming free unified data synchronization solution for free software desktops such as KDE, commonly used as part of the GNU/Linux operating system.

Hi Cornelius, Armin and Tobias. As you are now getting close to version 1.0 of OpenSync, which is expected to become the new synchronisation framework for KDE and other free desktops, we are quite interested in the merits it can provide for KDE users and for developers, as well as for the Open Source Community as a whole. So there’s one key-question before I move deeper into the details of OpenSync:

What does OpenSync accomplish, that no one did before?

Cornelius:

First of all it does its job of synchronizing data like addressbooks and calendars between desktop applications and mobile devices like PDAs and cell phones.

But the new thing about OpenSync is that it isn’t tied to a particular device or a specific platform. It provides an extensible and modular framework that is easy to adopt for application developers and people implementing support for syncing with mobile devices.

OpenSync is also independent of the desktop platform. It will be the common syncing backend for at least KDE and GNOME and other projects are likely to join. That means that the free desktop will have one common syncing solution. This is something really new.

How do the end-users profit from using synching solutions that interface with OpenSync as framework?

Cornelius:

First, the users will be able to actually synchronize all their data. By using one common framework there won’t be any “missing links”, where one application can sync one set of devices and another application a different one. With OpenSync all applications can sync all devices.

Second, the users will get a consistent and common user interface for syncing across all applications and devices. This will be much simpler to use than the current incoherent collection of syncing programs you need if you have more than the very basic needs.

How does OpenSync help developers with coding?

Cornelius:

It’s a very flexible and well-designed framework that makes it quite easy for developers to add support for new devices and new types of data. It’s also very easy to add support for OpenSync to applications.

The big achievement of OpenSync is that it hides all the gory details of syncing from the developers who work on applications and device support. That makes it possible for the developers to concentrate on their area of expertise without having to care what’s going on behind the scenes.

I have written quite a lot of synchronization code in the past. Trust me, it’s much better, if someone just takes care of it for you, and that’s what OpenSync does.

Tobias:

Another point to mention is the python wrapper for opensync, so you are not bound to C or C++, but can develop plugins in a high level scripting language.

Why should producers of portable devices get involved with your team?

Cornelius:

OpenSync will be the one common syncing solution for the free desktop. That means there is a single point of contact for device manufacturers who want to add support for their devices. That’s much more feasible than addressing all the different applications and solutions we had before. With OpenSync it hopefully will become interesting for manufacturers to officially support Linux for their devices.

Do you also plan to support applications of OpenSync in proprietary systems like OSX and Windows?

Cornelius:

OpenSync is designed to be cross-platform, so it is able to run on other systems like Windows. How well this works is always a question of people actually using and developing for this system. As far as I know there isn’t a real Windows community around OpenSync yet. But the technical foundation is there, so if there is somebody interested in working on a unified syncing solution on Windows, everybody is welcome to join the project.

What does your synchronisation framework do for KDE and for KitchenSync in particular?

Cornelius:

OpenSync replaces the KDE-specific synchronization frameworks we had before. Even in KDE we had several separate syncing implementations and with OpenSync we can get replace them with a common framework. We had a more generic syncing solution in KDE under development. This was quite similar from a design point of view to OpenSync, but it never got to the level of maturity we would have needed, because of lack of resources. As OpenSync fills this gap we are happy to be able to remove our old code and now concentrate on our core business.

What was your personal reason for getting involved with OpenSync?

Cornelius:

I wrote a lot of synchronization code in the past, which mainly came from the time where I was maintaining KOrganizer and working on KAddressBook. But this always was driven by necessity and not passion. I wanted to have all my calendar and contact data in one place, but my main objective was to work on the applications and user interfaces handling the data and not on the underlying code synchronizing the data.

So when the OpenSync project was created I was very interested. At GUADEC in Stuttgart I met with Armin, the maintainer of OpenSync, and we talked about integrating OpenSync with KDE. Everything seemed to fit together quite well, so at Linuxtag the same year we had another meeting with some more KDE people. In the end we agreed to go with OpenSync and a couple of weeks later we met again in Nuernberg for three days of hacking and created the KDE frontend for OpenSync. In retrospect it was a very pleasant and straightforward process to get where we are now.

Armin:

My reason to get involved (or better to start) OpenSync was my involvement with its predecessor Multisync. I am working as a system administrator for a small consulting company and so I saw some problems when trying to find a synchronization solution for Linux.

At that point I joined the Multisync project to implement some plugins that I thought would be nice to have. After some time I became the maintainer of the project. But I was unhappy with some technical aspects of the project, especially the tight coupling between the syncing logic and the GUI, its dependencies on GNOME libraries and its lack of flexibility.

Tobias:

Well, I have been a KDE PIM developer for several years now, so there was no way around getting in touch with synchronization and KitchenSync. Although I liked the idea of KitchenSync, I hated the code and the user interface […]. So when we discussed to switch to OpenSync and reimplementing the user interface, I volunteered immediately.

Can you tell us a bit about your further plans and ideas?

Cornelius:

The next thing will be the 1.0 release of OpenSync. We will release KitchenSync as frontend in parallel.

Armin:

There are of course a lot of things on my todo and my wishlist for opensync. For the near future the most important step is the 1.0 release, of course, where we still have some missing features in OpenSync as well as in the plugins.

One thing I would really like to see is a thunderbird plugin for OpenSync. I use thunderbird personally and would really like to keep my contacts up to date with my cellular, but I was not yet able to find the time to implement it.

Tobias:

One thing that would really rock in future versions of OpenSync is an automatic hardware detection mechanism, so when you plugin your Palm or switch on your bluetooth device, OpenSync will create a synchronization group automatically and ask the user to start syncing. To bring OpenSync to the level of _The Syncing Solution [tm]_ we must reduce the necessary configuration to a minimum.

What was the most dire problem you had to face when creating OpenSync and how did you face it?

Cornelius:

Fortunately the problems which I personally would consider to be dire are solved by the implementation of OpenSync which is well hidden from the outside world and [they are] an area I didn’t work on 😉

Armin:

I guess that I am the right person to answer this question then 🙂

The most complicated part of OpenSync is definitely the format conversion, which is responsible for converting the format of one device to the format that another device understands.

There are a lot of subsystems in this format conversion that make it so complex, like conversion path searching, comparing items, detection of mime types and last but not least the conversion itself. So this was a hard piece of work.

What was the greatest moment for you?

Cornelius:

I think the greatest moment was when, after three days of concentrated hacking, we had a first working version of the KDE frontend for OpenSync. This was at meeting at the SUSE offices in Nuernberg and we were able to successfully do a small presentation and demo to a group of interested SUSE people.

Armin:

I don’t remember a distinct “greatest moment”. But what is a really great feeling is to see that a project catches on, that other people get involved, use the code you have written and improve it in ways that you haven’t thought of initially.

Tobias:

Hmm, also hacking on OpenSync/KitcheSync is much fun in general, the greatest moment was when the new KitchenSync frontend synced two directories via OpenSync the first time. But it was also cool when we managed to get the IrMC plugin working again after porting it to OpenSync.

As we now know the worst problem you faced and your greatest moment, the only one missing is: What was your weirdest experience while working on OpenSync?

Cornelius:

Not directly related to OpenSync, but pretty weird was meeting a co-worker at the Amsterdam airport when returning from the last OpenSync meeting. I don’t know how high the chance is to meet somebody you know on a big random airport not related at all to the places where you or the other person live, but it was quite surprising.

Tobias:

Since my favorite language is C++, I was always confused how people can use plain C for such a project, half the time your are busy with writing code for allocating/freeing memory areas. Nevertheless Armin did a great job and he is always a help for solving strange C problems 🙂

Now I’d like to move on to some more specific questions about current and planned abilities of OpenSync. As first, I’ve got a personal one:

I have an old iPod sitting around here. Can I or will I be able to use a program utilizing OpenSync to synchronize my calendars, contacts and music to it?

Cornelius:

I’m not aware of any iPod support for OpenSync up to now, but if it doesn’t exist yet, why not write it? OpenSync makes this easy. This is a chance for everybody with the personal desire to sync one device or another to get involved.

Armin:

I dont think that there is iPod support yet for OpenSync. But it would definitely be possible to use OpenSync for this task. So if someone would like to implement an iPod plugin, I would be glad to help 🙂

Which other devices do you already support?

Cornelius:

At this time, OpenSync supports Palms, SyncML and IrMC capable devices.

Which programs already implement OpenSync and where can we check back to find new additions?

Cornelius:

On the application side there is support for Evolution [GNOME] and Kontact with KitchenSync [KDE] on the frontend side and the backend side and some more. I expect that further applications will adopt OpenSync once the 1.0 version is released.

Armin:

Besides kitchensync there already are a command line tool and a port of the multisync GUI. Aside from the GUIs, I would really like to see OpenSync being used in other applications as well. One possibility for example would to be integrate OpenSync into Evolution to give users the possibility to synchronize their devices directly from this application. News can generally be found on the OpenSync web site www.opensync.org.

It is time to give the developers something to devour, too. I’ll keep this as a short twice-fold technical dive before coming to the takeoff question, even though I’m sure there’s information for a double-volume book on technical subleties.

As first dive: How did you integrate OpenSync in KitchenSync, viewed from the coding side?

Cornelius:

OpenSync provides a C interface. We wrapped this with a small C++ library and put KitchenSync on top. Due to the object oriented nature of the OpenSync interfaces this was quite easy.

Recently I also started to write a D-Bus frontend for OpenSync. This also is a nice way to integrate OpenSync which provides a wide variety of options regarding programming languages and system configurations.

And for the second, deeper dive:

Can you give us a quick outline of those inner workings of OpenSync, from the developers view, which make OpenSync especially viable for application in several different desktop environments?

Cornelius:

That’s really a question for Armin. For those who are interested I would recommend to have a look at the OpenSync website. There is a nice white paper about the internal structure and functionality of OpenSync.

Armin:

OpenSync consists of several parts:

First there is the plugin API which defines what functions a plugin has to implement so that OpenSync can dlopen() it. There are 2 types of plugins:

A sync plugin which can synchronize a certain device or application and which provides functions for the initialization, handling the connection to a device and reading and writing items. Then there is a format plugin which defines a format and how to convert, compare and detect it.

The next part is a set of helper functions which are provided to ease to programming of synchronization plugins. These helper functions include things like handling plugin config files, HashTables which can be used to detect changes in sets of items, functions to detect when a resync of devices is necessary etc.

The syncing logic itself resides in the sync engine, which is a separate part. The sync engine is responsible for deciding when to call the connect function of a plugin, when to read or write from it. The engine also takes care of invoking the format conversion functions so that each plugin gets the items in its required format.

If you want more information and details about the inner workings of OpenSync, you should really visit the opensync.org website or ask its developers.

To add some more spice for those of our readers, whose interest you just managed to spawn (or to skyrocket), please tell us where they can get more information on the OpenSync Framework, how they can best meet and help you and how they can help improving sync-support for KDE by helping OpenSync.

Cornelius:

Again, the OpenSync web site is the right source for information. Regarding the KDE side, the kde-pim@kde.org mailing list is probably the right address. At the moment the most important help would be everything which gets the OpenSync 1.0 release done.

[And even though] I already said it, it can’t be repeated too often: OpenSync will be the one unified syncing solution for the free desktop. Cross-device, cross-platform, cross-desktop.

It’s the first time I feel well when thinking about syncing 😉.

Armin:

Regarding OpenSync, the best places to ask would be the opensync mailing lists at sourceforge or the #opensync irc channel on the freenode.net servers.

There are always a lot of things where we could need a helping hand and where we would be really glad to get some help. So everyone who is interested in OpenSync is welcome to join.

Many thanks for your time!

Cornelius:

Thanks for doing the interview. It’s always fun to talk about OpenSync, because it’s really the right thing.

Armin:

Thank you for taking your time and doing this interview. I really appreciate your help!

Tobias:

Thanks for your work. Publication and marketing is something that is really missing in the open source community. We have nice software but nobody knows 😉

Apple Computer CEO and co-founder Steve Jobs gave his annual opening keynote to the World Wide Developers Conference (WWDC) at Moscone Center in San Francisco, California on Monday. He announced a seamless integration of podcasting with iTunes, and, to the amazement of many, that future Apple Macintosh computers will feature Intel processors.

Jobs welcomed everyone to the event and announced that there were 3,800 attendees. There are 500 Apple engineers at what is their largest developers conference in the past decade. There are over 500,000 developers of Apple programs (apps). Jobs said that Apple has 109 retail stores, with one million visitors per week, creating over $500 million yearly in revenue. The Mac market share is up 82% from 9 months ago.

Jobs then moved on to talk about a very anticipated announcement- Podcasting. Steve called podcasting “Wayne’s World for radio”. He called it the “hottest thing going in radio”, and, “exciting”. There are over 8,000 podcasts. Steve Jobs announced that automatic podcasting subscription would be built in to iTunes and iPod seamlessly. He also announced that QuickTime 7 would be soon available for Windows.

Moving on, Jobs announced that there have been 2 million copies of Tiger sold in the 6 weeks that it has been available. He demoed the Wikipedia Dashboard widget. Steve announced that Mac OS X Leopard would be released in 2007, the same time as Microsoft’s Longhorn.

In a surprising move, Steve Jobs announced that Macintosh computers would begin to be shipped with Intel processors, the same as in Windows machines, ending the eleven year partnership with IBM and Motorola. This is said to be out of Apple’s increasing frustration at IBM’s inability to deliver faster and cooler processors, though it is interesting to note that Intel has recently added Digital Rights/Restrictions Management (DRM) to its latest processors. This ‘switch’, he said, would happen beginning next year. Jobs said that Mac OS X has had “a secret double life” and OS X had “been compiled [for Intel processors] for five years.” He talked about the easiness for developers to port their Mac apps to Intel (x86) processors. Current PowerPC programs can be run on Intel processors due to a new Apple technology. He said that Apple is “getting ready” for the transition from PowerPC to Intel.
