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 😉

A number of properties in a Hare Krishna village in Kazakhstan were demolished on November 21, by the local authorities, causing international outrage by religious freedom groups and Hindu associations alike. Since the attack fears are now rising within the community of further demolition to the remaining properties, including the main temple structure.

“The community is in shock, but they are determined to defend their homes and place of worship,” community member Govinda Swami told Forum 18 News Service. He says destruction of the temple would be “devastating”.

The authorities in Kazaksthan claim that the Hare Krishna devotees had no official right to their homes. However human rights activists Ninel Fokina and Andrei Grishin, state in reply that while 13 out of the 66 Hare Krishna homes were destroyed on court orders, “the adjacent houses of other people who do not belong to the Society for Krishna Consciousness were left untouched even though their title deeds have the same status”.

The Hare village itself, known as ‘Sri Vrindavan Dham commune’ (named after Vrindavan forest in India is based in the Keskelen district, in the town of Seleksia, close to Almaty. It was the only village of it’s type run by Hare Krishna devotees in the country.

According to human rights activist Yevgeni Zhovtis: “Unfortunately Kazakh law does not prohibit evictions during the winter period and also does not oblige the court bailiffs to give those being evicted a few days notice,” “All the same, there were crude violations of the law. The court bailiffs had the right to evict the residents of the houses but not to demolish the buildings themselves. It was also a very crude violation to throw the belongings of the Krishna devotees into the mud. The court bailiffs were obliged to put the devotees’ belongings into store.”

Local journalist Grishin claims to have had his camera confiscated by the Police and to have been threatened “If I see you here again, I will personally smash your eyes, even though I am the hakim.”

Protests are being made by Hindu groups and members of the International Society for Krishna Consciousness around the world in an attempt to halt any further demolition or other forms of alleged religious persecution. Groups within the UK have brought the issue to the attention of both Tony Blair, and the House of Commons.

One of the Indian political parties, Bharatiya Janata Party criticised the central government for keeping silence over the issue. The party is expected to follow the saffron brotherhood agenda in the second term of Rajnath Singh.

Reggie Bibbs is a 43-year-old-man living in Houston, Texas. Mr Bibbs was born with a genetic disease called neurofibromatosis (NF), which causes him to develop tumors on his body (see infobox on the right). NF can be a subtle disease, but in Bibbs’ case it has left him with a disfigured face and deformed leg. But he is happy with the way he looks, and doesn’t want to change his appearance to please other people. He has launched a successful campaign entitled “Just Ask”, and that’s just what Wikinews did in a video-interview.

The interview was prepared by Wikinews reporter Michaël Laurent with the help of Bertalan Meskó (who has a popular genetics and web 2.0 blog). Their questions were sent to a close friend of Mr. Bibbs, Lou Congelio, who kindly conducted the interview.

Highland Airways, which runs flights between Anglesey in north Wales and Cardiff in south Wales, has said today that it is business as usual, despite suspending online booking yesterday. Meanwhile, Liberal Democrats have called on the Welsh Assembly Government to withdraw the £800,000 annual public subsidy for the route (about US$1.3 million) and use the money on “green public transport” instead.

Although flights were continuing and passengers were told to “check in as normal”, the company stopped taking bookings for future flights yesterday, blaming “technical difficulties”. However, it also said that trading conditions were “difficult”. The company’s commercial director, Basil O’Fee, explained that the company’s problems had been “exacerbated by the severe winter and resultant reduced flying and reduced income.” He added that the board was in talks with potential new investors, and hoped for a outcome of these discussions to be known “within days rather than weeks”.

“It is now time to end this costly debacle before even more public money is poured into a service that is both economically and environmentally unsustainable,” according to Kirsty Williams, leader of the Welsh Liberal Democrats. She wants the money spent on improving rail transport in Wales.

However, Ieuan Wyn Jones, the leader of the Welsh nationalist party Plaid Cymru and the Assembly member for Anglesey, said that the service was an “essential link”. He hoped that the company would be able to keep going, or in a “worse case scenario”, that the route would be run by administrators while the Assembly Government looked at other options.

The company has carried 37,000 people on its twice-daily service since it started operating. According to Jones, this showed that that the service “has been a huge success with passenger numbers far exceeding expectations”.

Bidding for the next contract with the Assembly Government to provide the route closed last week, with Highland Airways thought to be the only entrant. The lack of other bids was “particularly worrying”, commented Jenny Randerson, Welsh Liberal Democrats transport spokesperson. “This does suggest that despite huge public subsidy, this service is still not seen as a viable, profitable, and green solution to this key transport need”, she said.

Highland Airways is based in Inverness, Scotland, where it operates passenger and freight services for island communities. The news that the company was in difficulty was said to come as a surprise to business and transport leaders in Scotland, where it is regarded as a “Highland success story”.

Evansville, Indiana, United States — This past week marked the opening night of an Andy Warhol exhibit at the University of Southern Indiana. USI’s art gallery, like 189 other educational galleries and museums around the country, is a recipient of a major Warhol donor program, and this program is cultivating new interest in Warhol’s photographic legacy. Wikinews reporters attended the opening and spoke to donors, exhibit organizers and patrons.

The USI art gallery celebrated the Thursday opening with its display of Warhol’s Polaroids, gelatin silver prints and several colored screen prints. USI’s exhibit, which is located in Evansville, Indiana, is to run from January 23 through March 9.

The McCutchan Art Center/Pace Galleries at USI bases its exhibit around roughly 100 Polaroids selected from its collection. The Polaroids were all donated by the Andy Warhol Photographic Legacy Program, according to Kristen Wilkins, assistant professor of photography and curator of the exhibit. The Andy Warhol Foundation for the Visual Arts made two donations to USI Art Collections, in 2007 and a second recently.

Kathryn Waters, director of the gallery, expressed interest in further donations from the foundation in the future.

Since 2007 the Andy Warhol Photographic Legacy Program has seeded university art galleries throughout the United States with over 28,000 Andy Warhol photographs and other artifacts. The program takes a decentralized approach to Warhol’s photography collection and encourages university art galleries to regularly disseminate and educate audiences about Warhol’s artistic vision, especially in the area of photography.

Wikinews provides additional video, audio and photographs so our readers may learn more.

Wilkins observed that the 2007 starting date of the donation program, which is part of the Andy Warhol Foundation for the Visual Arts, coincided with the 20th anniversary of Andy Warhol’s death in 1987. USI was not alone in receiving a donation.

K.C. Maurer, chief financial officer and treasurer at the Andy Warhol Foundation, said 500 institutions received the initial invitation and currently 190 universities have accepted one or more donations. Institutional recipients, said Mauer, are required to exhibit their donated Warhol photographs every ten years as one stipulation.

While USI is holding its exhibit, there are also Warhol Polaroid exhibits at the Tang Teaching Museum and Art Gallery at Skidmore College in Saratoga Springs, New York and an Edward Steichen and Andy Warhol exhibit at the Mary & Leigh Block Museum of Art at Northwestern University in Evanston, Illinois. All have received Polaroids from the foundation.

University exhibits can reach out and attract large audiences. For example, the Weatherspoon Art Museum at the University of North Carolina at Greensboro saw attendance levels reach 11,000 visitors when it exhibited its Warhol collection in 2010, according to curator Elaine Gustafon. That exhibit was part of a collaboration combining the collections from Duke University, located in Durham, North Carolina, and University of North Carolina at Chapel Hill, which also were recipients of donated items from the Andy Warhol Photographic Legacy Program.

Each collection donated by the Andy Warhol Photographic Legacy Program holds Polaroids of well-known celebrities. The successful UNC Greensboro exhibit included Polaroids of author Truman Capote and singer-songwriter Carly Simon.

“I think America’s obsession with celebrity culture is as strong today as it was when Warhol was living”, said Gustafon. “People are still intrigued by how stars live, dress and socialize, since it is so different from most people’s every day lives.”

Wilkins explained Warhol’s obsession with celebrities began when he first collected head shots as a kid and continued as a passion throughout his life. “He’s hanging out with the celebrities, and has kind of become the same sort of celebrity he was interested in documenting earlier in his career”, Wilkins said.

The exhibit at USI includes Polaroids of actor Dennis Hopper; musician Nick Rhodes of Duran Duran; publishers Jann Wenner of Rolling Stone Magazine and Carlo De Benedetti of Italy’s la Repubblica; disco club owner Steve Rubell of Studio 54; photographers Nat Finkelstein, Christopher Makos and Felice Quinto; and athletes Vitas Gerulaitis (tennis) and Jack Nicklaus (golf).

Wikinews observed the USI exhibit identifies and features Polaroids of fashion designer Halston, a former resident of Evansville.

University collections across the United States also include Polaroids of “unknowns” who have not yet had their fifteen minutes of fame. Cynthia Thompson, curator and director of exhibits at the University of Arkansas, Fayetteville, said, “These images serve as documentation of people in his every day life and art — one which many of us enjoy a glimpse into.”

Warhol was close to important touchstones of the 1960s, including art, music, consumer culture, fashion, and celebrity worship, which were all buzzwords and images Wikinews observed at USI’s opening exhibit.

He was also an influential figure in the pop art movement. “Pop art was about what popular American culture really thought was important”, Kathryn Waters said. “That’s why he did the Campbell Soup cans or the Marilyn pictures, these iconic products of American culture whether they be in film, video or actually products we consumed. So even back in the sixties, he was very aware of this part of our culture. Which as we all know in 2014, has only increased probably a thousand fold.”

“I think everybody knows Andy Warhol’s name, even non-art people, that’s a name they might know because he was such a personality”, Water said.

Hilary Braysmith, USI associate professor of art history, said, “I think his photography is equally influential as his graphic works, his more famous pictures of Marilyn. In terms of the evolution of photography and experimentation, like painting on them or the celebrity fascination, I think he was really ground-breaking in that regard.”

The Polaroid format is not what made Warhol famous, however, he is in the company of other well-known photographers who used the camera, such as Ansel Adams, Chuck Close, Walker Evans, Robert Mapplethorpe, and Helmut Newton.

Wilkins said, “[Warhol] liked the way photo booths and the Polaroid’s front flash looked”. She explained how Warhol’s adoption of the Polaroid camera revealed his process. According to Wilkins, Warhol was able to reproduce the Polaroid photograph and create an enlargement of it, which he then could use to commit the image to the silk screen medium by applying paint or manipulating them further. One of the silk screens exhibited at USI this time was the Annie Oakley screen print called “Cowboys and Indians” from 1987.

Wilkins also said Warhol was both an artist and a businessperson. “As a way to commercialize his work, he would make a blue Marilyn and a pink Marilyn and a yellow Marilyn, and then you could pick your favorite color and buy that. It was a very practical salesman approach to his work. He was very prolific but very business minded about that.”

“He wanted to be rich and famous and he made lots of choices to go that way”, Wilkins said.

Kiara Perkins, a second year USI art major, admitted she was willing to skip class Thursday night to attend the opening exhibit but then circumstances allowed for her to attend the exhibit. Why did she so badly want to attend? “It’s Warhol. He is a legend.”

For Kevin Allton, a USI instructor in English, Warhol was also a legend. He said, “Andy Warhol was the center of the Zeitgeist for the 20th century and everything since. He is a post-modern diety.”

Allton said he had only seen the Silver Clouds installation before in film. The Silver Clouds installation were silver balloons blown up with helium, and those balloons filled one of the smaller rooms in the gallery. “I thought that in real life it was really kind of magical,” Allton said. “I smacked them around.”

Elements of the Zeitgeist were also playfully recreated on USI’s opening night. In her opening remarks for attendees, Waters pointed out those features to attendees, noting the touches of the Warhol Factory, or the studio where he worked, that were present around them. She pointed to the refreshment table with Campbell’s Soup served with “electric” Kool Aid and tables adorned with colorful gumball “pills”. The music in the background was from such bands as The Velvet Underground.

The big hit of the evening, Wikinews observed from the long line, was the Polaroid-room where attendees could wear a Warhol-like wig or don crazy glasses and have their own Polaroid taken. The Polaroids were ready in an instant and immediately displayed at the entry of the exhibit. Exhibit goers then became part of the very exhibit they had wanted to attend. In fact, many people Wikinews observed took out their mobiles as they left for the evening and used their own phone cameras to make one further record of the moment — a photo of a photo. Perhaps they had learned an important lesson from the Warhol exhibit that cultural events like these were ripe for use and reuse. We might even call these exit instant snap shots, the self selfie.

Yesterday, at this year’s Apple Worldwide Developers Conference (WWDC), company CEO Steve Jobs unveiled iPhone 4, along with the new iOS 4 operating system for Apple mobile devices.

The announcement was long-awaited but not a very big surprise. In April, the technology blog Gizmodo obtained a prototype of the new phone and published details of it online. While introducing iPhone 4, at the annual conference, Jobs started by hinting at the incident, saying, “Stop me if you’ve already seen this.”

The new iPhone was praised by Jobs as “the biggest leap we’ve taken since the original iPhone.” It is only 9.3 millimetres (0.37 inches) thick, making it “the thinnest smartphone on the planet”, a 24 percent reduction from Apple’s previous model, the iPhone 3GS. Structure-wise, iPhone 4 has a new stainless steel frame, which acts as an antenna, supposedly boosting its signal reception abilities and possibly reducing the amount of dropped calls. It also has a new screen, dubbed a “retina display,” which displays images at 326 pixels per inch. During the keynote, Jobs demoed the device’s new internal gyroscope as well. Even though it now uses Apple’s faster A4 processor (first used in its iPad tablet), iPhone 4 has a claimed seven hours of 3G talk time, up two hours from the 3GS.

In addition to its design features, Jobs showed off iPhone 4’s new video calling abilities. This feature is called FaceTime, and connects with other iPhone 4s via Wi-Fi. The phone has two cameras: one on the front for video chats, and one on the back for taking pictures and other videos. The rear camera has a resolution of five megapixels, is capable of recording high-definition video, and has an LED flash.

The iPhone 4 will use Apple’s latest mobile operating system, iOS 4. Formerly “iPhone OS,” iOS 4 was first introduced by Apple in April, and includes multitasking capabilities. Jobs called the new software “the most advanced mobile operating system in the world.” iOS will support Apple’s new mobile advertising service, iAd, which goes live on July 1.

iPhone 4 will be available on June 24 in the United States, United Kingdom, France, Germany, and Japan. It comes in two colors—black and white—and two storage capacities. The 16GB version is priced at US$199 and the 32GB version at US$299. The iPhone 3GS’s price will be reduced to US$99, and the iPhone 3G will be discontinued. iOS will be available as a free software update to users of compatible older Apple devices (including the 3GS) on June 21. In the U.S., iPhone 4 will only be available on AT&T’s cellular network, despite calls for Apple to let the iPhone be used on other carriers, such as Verizon.

Competition-wise, the BlackBerry mobile device is still the most popular smartphone right now. Apple is also facing some serious competition from web giant Google’s Android operating system, as well as Palm’s webOS. Earlier this year, Android phones managed to outsell iPhones. iPhone users, however, account for over half of those surfing the Internet on a mobile browser in the U.S. Jobs also noted that over five billion iOS applications, commonly called “apps,” have been purchased from Apple’s App Store. The App Store currently has around 225,000 different apps for sale.

Just five years ago, when Jimbo Wales founded Wikipedia, the project’s goal of 100,000 articles [1] seemed ambitious. Yet today, the project, now one of the top 25 websites in the world according to Alexa, is nearing closer 1,000,000 articles in English, and 3.5 million articles across all languages. This week, we interviewed Jimbo Wales.

Colored version

Wikinews: Raul654 asks: “Recently, there were revelations about organized attempts by US Congressmen to whitewash their articles. What is your take on this, as well as earlier reports of Corporate astroturfing?”

Jimbo Wales: The question is invalid. There were no revelations of organized attempts by US Congressmen to whitewash their articles. Not any evidence of “corporate astroturfing” of which I am aware. There was evidence that some congressional staffers edited Wikipedia in inappropriate ways. But the internal evidence of the type and style of these edits do not suggest “organized attempts”.

WN: Nichalp asks: “Budget permitting, are there any plans to increase the number of Wikipedia servers, specifically into the less developed countries?”

JW: We are always buying new servers. There are no specific plans to add servers in less developed countries, but we have looked into it as a possibility. We are particularly interested in doing so if it helps increase access and reduce costs for those users.

WN: An anonymous reader asks: “How much of a role do you feel the Wikipedia community (and the communities of its sister projects) should have in the running of the Wikimedia Foundation? Do you see an increasing separation of the organization from the projects? If so, do you regard that as beneficial or a potential problem?”

JW: The community has always been and will always be absolutely crucial to the running of the Wikimedia Foundation. We are increasing the community input and activity in the foundation through a new series of committees to delegate things to community members which have traditionally been handled by me or the Board. I do not see any increasing separation of the organization from the projects, quite the opposite. I consider the increasing integration of the community and the foundation as overwhelmingly beneficial.

WN: ALoan asks: “English Wikipedia is approaching 1 million articles, but less than 1 in a thousand are Featured articles. The list of featured articles English Wikipedia should have has few featured articles, and recent surveys of articles chosen at random show that many articles are poorly written. How can we get from here to an encyclopedia of well-written articles? Or should we not worry too much about coverage and content?”

JW: We should be tightly focused on the quality of our coverage and content. The goal of Wikipedia is to create and distribute a freely licensed high quality encyclopedia. The path to that goal will require us to be flexible and thoughtful. The first steps will come soon with the article review system, which will initially be used simply to gather data. After we have data, we can begin to work on how we will focus our attention to improve quality.

WN: GeorgeStepanek asks: “You’ve said that ‘Wikimedia’s mission is to give the world’s knowledge to every single person on the planet in their own language.’ But very few of the wikipedias in the languages of third-world countries are seeing as much activity as the first-world language wikipedias. Do you have any ideas on how this could be turned around?”

JW: I am a believer in outreach. I would like for the Foundation to raise money specifically to pay one or more minority language co-ordinators. The goal would be to reach out in a more organized way to professors and graduate students and expat communities who have good Internet access, to seed projects for languages where the majority of speakers have poor internet access.

WN: Jacoplane asks: “How do you feel we will be able to reach Wikipedia 1.0? The tools currently available for vetting our articles are crude at best. The Featured article process seems too slow, and the article validation feature seems to have died a quiet death. Are you planning a big push on this front?”

JW: Isn’t that the same question as the quality question? The article validation feature has not died a quiet death at all.

WN: Quadell asks: “Most important decisions on Wikimedia projects are handled with consensus. However, we sometimes have to deal with legal issues, especially related to copyright law. For instance, we as a community may need to decide whether to consider a certain use “fair”, or how to deal with conflicting copyright claims. Dealing with this through consensus is problematic, since we can’t do something illegal even if there is widespread misguided support for it. In general, how can we as a community deal with these issues?”

JW: I don’t think there is any real problem with this. The community is strongly in support of following the law. I don’t know of any particular cases of widespread misguided support for something illegal. In particular cases, there can of course be [dis]agreement, but I have never seen anyone in the community argue that we should not listen to the advice of our legal team.

WN: Raul654 asks: “Where do you see Wikipedia in 10 years?”

JW: I don’t know. My favorite answer to this is to say, the real question is: where will the world be after 10 more years of Wikipedia. 🙂 Seriously, I think we’ll eventually see a tapering off of new article creation in the large language wikipedias as more and more “verifiable” topics are covered. At this point, most changes will be expansions and updates and quality improvements to existing articles. But in 10 years, it seems likely to me that many languages which are now quite small will have very large Wikipedia projects. Our community will continue to become more diverse as more and more people worldwide come online.

WN: Kevin Myers asks: “The values reflected in certain Wikipedia policies (anti-censorship, neutral point-of-view) are problematic in cultures where freedom of expression is limited, as the blocking of Wikipedia in mainland China and arguably the Muhammad cartoons controversy attest. As Wikipedia expands internationally, do you foresee Wikipedia becoming increasingly controversial in countries where “Western values” are seen as a potential threat?”

JW: I don’t think that neutrality and objectivity are really controversial among most people of the world. It is true that the leadership in some places does not value these things, and may actually work against these things, but we can not deviate from our goals to accommodate them.

WN: On a similar topic, Vsion asks: “Are there currently any efforts being undertaken by the Foundation to address the People’s Republic of China’s blocking of Wikipedia or to alleviate its effect?”

JW: Beijing-area Wikipedians are working to have the block lifted. Our position is that the block is in error, even given China’s normal policies. Wikipedia is not propaganda, it is basic information. We expect that the block will be lifted.

WN: David.Monniaux asks: “The Foundation receives daily accusations of libel from semi-well-known people who have an entry on Wikipedia or are mentioned in some Wikipedia entry. What do you propose? Would a strict application of the rule of citing controversial claims suffice, in your opinion?”

JW: Yes. I think that our current systems do a good job of addressing these sorts of complaints, although it is very time-consuming for us here in the office. What really works wonders is a very strict application of the rule of citing controversial claims particularly relating to biographies of living persons. The new policy on biographies of living persons is a very strong step in the right direction.

WN: Tony Sidaway asks: “In the past six weeks the number of userboxes on English Wikipedia has risen from 3500 to 6000 and, despite your appeals for restraint, the number pertaining to political beliefs has risen from 45 to 150. Can the problem of unsuitable userboxes still be resolved by debate?”

JW: My only comment on the userbox situation is that the current situation is not acceptable.

WN: Larsinio asks: “How can Wikipedia effectively explain to the public its open-contribution model without simultaneously worrying the public about inaccurate information?”

JW: I think we do a reasonably good job of that. The best thing is to point to our overall quality while at the same time pointing out that we are currently a work in progress. Over time, this answer will change as we move toward ‘1.0’. At that time, we can point to ‘1.0’ for those who are made nervous by the live editing.

WN: Rob Church asks: “Do you consider the encyclopedia to be ‘finished’? Do you think it ever can be?”

JW: Nothing is ever finished. Human knowledge is always growing.

WN: Raul654 and Pavel Vozenilek both asked, “What kind of cool new features/announcements can we expect to see in the next year or two?”

JW: I think this question is too hard for me to answer. I almost never “announce” anything, and features are developed publicly by the community. I think other people have a better idea than I do what will happen in the next year or two. 🙂 Ask Brion [Vibber].

WN: Celestianpower asks: “If you had not founded Wikipedia, and had just been referred to it by a friend, how active a contributor do you think you would be?”

JW: [I] dream fondly of such a scenario. I might actually get to edit articles then. Instead of spend the morning (this morning) documenting transactions and taking phone calls.

WN: OpenToppedBus asks: “The last fundraising drive was less successful than had been anticipated. Do you see a shortage of money holding back Wikipedia/Wikimedia in the short-to-medium-term, and are there any plans to bring in income from sources other than individual donations?”

JW: The last fundraising drive was more successful than had been anticipated, by a long shot. It was the most successful fund drive in our history. [Regarding a quoted goal of $500,000], Mav wrote something like that somewhere, in a scratchpad kind of way. That number was just a placeholder and had nothing to do with me or the official view of the foundation. He’s apologized repeatedly for it.

WN: Thryduulf asks: “What is your single greatest wish for Wikipedia?”

JW: I would have to just point back to our original goal: a freely licensed high quality encyclopedia for every single person on the planet. That’s what I remain focused on daily.

Qatari non-profit organization Gulf Organization for Research and Development (GORD) launched a low emissions car at the 2012 United Nations Climate Change Conference (COP 18) in Doha. The car was designed and developed in Qatar.

Revealed during a press conference at the Qatar National Convention Centre, the car in addition to an internal combustion engine, includes an automotive thermoelectric generator designed to capture waste heat to produce hydrogen. GORD expects the heat waste collecting system to be compatible with any gasoline or compressed natural gas car.

GORD chairman Dr Al-Horr summarised the key concepts of the invention in a statement saying, “Our car produces electricity at no cost by capturing thermal waste energy, reducing costs and eliminating the need for an external source of electricity. Also, bulky compressed-hydrogen cylinders are a thing of the past, as our concept accomplishes the production of hydrogen by using water through fuel cells integrated within the car.”

Most of the energy in Qatari vehicle comes from the the car’s gasoline tank, supplemented by a thin film photo-voltaic panel on the roof. Normally in a combustion engine, chemical energy stored in a fuel, such as gasoline, is converted into heat energy through combustion. This heat energy is then converted into mechanical energy, manifested as an increase in pressure in the combustion chamber due to the kinetic energy of the combustion gases. The kinetic energy of these combustion gases are then converted into work; because of the inefficiencies in converting chemical energy into useful work, internal combustion engines have a theoretical maximum effiecincy of 37% (with what is achievable in day to day applications being about half of this). Of the chemical energy in the consumed fuel used by an internal combustion engine 40% is dissipated as waste heat. However, the Qatari vehicle uses a thermoelectric generator to convert this waste heat into electricity. Such generators are used in space vehicles, and produce electricity when thermoelectric materials are subjected to a temperature gradient, the greater the gradient the greater the amount of electrcity produced. In the GORD vehicle the electricity produced is used to electrolyse potable water to produce hydrogen which can be introduced into the vehicle’s existing fuel system.

The researchers showed that the heat waste collection engine caused a decrease in the car’s emissions, including a decrease of carbon monoxide and nitrous oxide emissions by more than 50%, the fuel efficiency increasing by 20%. On its website, GORD said that the heat waste collector engine is universal, “Any car can be adapted to accommodate the system as it doesn’t alter any electro-mechanical systems”.
