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 😉

Monday, March 21, 2005A piece of driftwood in the shape of a crucifix is listed for sale on eBay with a starting bid price of $25,000. The seller, known as “Marzipanda,” from Scottsdale, Arizona lists its description as a “Natural Found Wood Jesus Christ Crucifix Cross Easter.”

Maripanda describes the discovery of the piece as, “My very dear friend found this amazing natural driftwood while hiking a few years ago. So striking because it clearly resembles the Lord and all the details.”

Expensive found art Christiana made international headlines in November 2004 when a Florida woman named Diana Duyser sold a partially eaten grilled cheese sandwich on eBay for $28,000 to Canadian online gambling website, GoldenPalace.com, after claiming she saw the likeness of the Virgin Mary burned onto the toast.

But not all high-priced Christian fare on eBay is of dubious value. A perusal of Christian-themed items as of March 20, showed 13,944 for sale on eBay. They ranged from other found art to some very expensive and authenticated rare art.

One such item has an eBay seller from Tel-Aviv, Israel listing a 19th century iron wall plaque with a starting bid of $30,000 and a shipping cost of $2,000, making it the most-expensive Christian religious item listed for sale on the auction web site.

Under the “Christian Icons” section of the site, the 14 cast iron plaques are advertised to have been made in 1855 and portrays “Jesus in Jerusalem” with the 14 stations of Christ.

Another high-priced Christian-themed item is a set of chalices and paten in Ft. Lauderdale, Florida for $3,550. The gold-plated silver is thought to have been made in the 1870s.

The family of the 19 year old who was ‘murdered’ in a pub car park two days ago have made a statement regarding the death of their child. They said that “Jack is obviously dearly missed by all of his family. He was a much loved son and brother.”

“Nothing can ever fill the hole that has been left in our lives,” they continued. “We know that Jack had a lot of friends, but we have been amazed by the amount of messages that people have left. “

The family continued “we can not believe Jack has gone, we all keep expecting him to walk back in. Jack was an angel, he was amazing.”

The death, which was treated as murder, resulted in two arrests. The murder, which occurred on Wednesday evening, took place near Highridge Road in Bishopsworth, Bristol.

Sweden’s first royal wedding since 1976 took place Saturday when Crown Princess Victoria, 32, married her long-time boyfriend and former personal trainer, Daniel Westling, 36. The ceremony took place at Stockholm Cathedral.

Over 1,200 guests, including many rulers, politicians, royals and other dignitaries from across the world, attended the wedding, which cost an estimated 20 million Swedish kronor. Victoria wore a wedding dress with five-metre long train designed by Pär Engsheden. She wore the same crown that her mother, Queen Silvia, wore on her wedding day 34 years previously, also on June 19. Victoria’s father, King Carl XVI Gustaf, walked Victoria down the aisle, which was deemed untraditional by many. In Sweden, the bride and groom usually walk down the aisle together, emphasising the country’s views on equality. Victoria met with Daniel half-way to the altar, where they exchanged brief kisses, and, to the sounds of the wedding march, made their way to the the silver altar. She was followed by ten bridesmaids. The couple both had tears in their eyes as they said their vows, and apart from fumbling when they exchanged rings, the ceremony went smoothly.

Following the ceremony, the couple headed a fast-paced procession through central Stockholm on a horse-drawn carriage, flanked by police and security. Up to 500,000 people are thought to have lined the streets. They then boarded the Vasaorden, the same royal barge Victoria’s parents used in their wedding, and traveled through Stockholm’s waters, accompanied by flyover of 18 fighter jets near the end of the procession. A wedding banquet followed in the in the Hall of State of the Royal Palace.

Controversy has surrounded the engagement and wedding between the Crown Princess and Westling, a “commoner”. Victoria met Westling as she was recovering from bulemia in 2002. He owned a chain of gymnasiums and was brought in to help bring Victoria back to full health. Westling was raised in a middle-class family in Ockelbo, in central Sweden. His father managed a social services centre, and his mother worked in a post office. When the relationship was made public, Westling was mocked as an outsider and the king was reportedly horrified at the thought of his daughter marrying a “commoner”, even though he did so when he married Silvia. Last year, Westling underwent transplant surgery for a congenital kidney disorder. The Swedish public have been assured that he will be able to have children and that his illness will not be passed on to his offspring.

Westling underwent years of training to prepare for his new role in the royal family, including lessons in etiquette, elocution, and multi-lingual small talk; and a makeover that saw his hair being cropped short, and his plain-looking glasses and clothes being replaced by designer-wear.

Upon marrying the Crown Princess, Westling took his wife’s ducal title and is granted the style “His Royal Highness”. He is now known as HRH Prince Daniel, Duke of Västergötland. He also has his own coat-of-arms and monogram. When Victoria assumes the throne and becomes Queen, Daniel will not become King, but assume a supportive role, similar to that of Prince Phillip, the husband of the United Kingdom’s Queen Elizabeth II.

Viktor Schreckengost, the father of industrial design and creator of the Jazz Bowl, an iconic piece of Jazz Age art designed for Eleanor Roosevelt during his association with Cowan Pottery died yesterday. He was 101.

Schreckengost was born on June 26, 1906 in Sebring, Ohio, United States.

Schreckengost’s peers included the far more famous designers Raymond Loewy and Norman Bel Geddes.

In 2000, the Cleveland Museum of Art curated the first ever retrospective of Schreckengost’s work. Stunning in scope, the exhibition included sculpture, pottery, dinnerware, drawings, and paintings.

Rebels from the Hutu-extremist “Forces Nationales de Liberation” have shot dead six churchgoers in Muhuta district, Bujumbura-Rural, according to army spokesman Adolphe Manirakiza.

“The first criminal attack was committed in one church at Muhuta district where a group of FNL fighters fired in the church and killed six people including a pastor. They also injured seven others”, Manirakiza said.

He said the rebels shot dead a local government official and his brother and also kidnapped a policeman in the same district.

“We don’t know yet why these people were killed, they may be executed because they refused to adhere to the FNL ideology, as the area where they have been killed is an FNL stronghold.”

Some 300,000 people have been killed since the fighting began in 1993.

Fresh talks between the government and the FNL have raised hopes among diplomats that Burundi can finally lift one of its last big barriers to peace.

Its leader Agathon Rwasa and Burundi President, Domitien Ndayizeye signed on May 15 in Dar es Salaam, Tanzania, a cessation of hostilities deal seen as a significant step toward finally bringing the rebels into the peace process.

But the rebels and the army have clashed sporadically since the truce.

Wikinews extended invitations by e-mail on March 23 to multiple candidates running in the Texas’ 6th congressional district special election of May 1 to fill a vacancy left upon the death of Republican congressman Ron Wright. Of them, the office of Democrat Daryl Eddings, Sr. agreed to answer some questions by phone March 30 about their campaigns and policies. The following is the interview with Ms Chatham on behalf of Mr Eddings, Sr.

Eddings is a federal law enforcement officer and senior non-commissioned officer in the US military. His experience as operations officer of an aviation unit in the California National Guard includes working in Los Angeles to control riots sparked by the O. J. Simpson murder case and the police handling of Rodney King, working with drug interdiction teams in Panama and Central America and fighting in the Middle East. He is the founder of Operation Battle Buddy, which has under his leadership kept in touch with over 20 thousand veterans and their families. He was born in California, but moved to Midlothian, Texas. He endeavours to bring “good government, not no government”. Campaign manager Faith Chatham spoke to Wikinews on matters ranging from healthcare to housing.

An Inside Elections poll published on March 18 shows Republican candidate Susan Wright, the widow of Ron Wright, is ahead by 21% followed by Democrat Jana Sanchez with 17% and Republican Jake Ellzey with 8% with a 4.6% margin of error among 450 likely voters. The district is considered “lean Republican” by Inside Elections and voted 51% in favour of Donald Trump in last year’s US presidential election. This is down from 54% for Trump in 2016’s presidential election, the same poll stated.
