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 😉

Drivers on Britain’s M3 motorway were stunned to be confronted with a shower of cash on Tuesday evening.

Eleven thousand pounds‘ worth of £20 notes were blown from the rucksack of a passenger on a motorcycle at 7:30pm, while the motorway was busy with traffic.

Just £500 was recovered; the rest is believed to have been blown away in the windy evening. At least four other drivers quickly stopped, causing Hampshire police concern for safety.

The police are now investigating as to why the pair were carrying so much money. Carrying large amounts of money is not illegal, but is highly unusual. The riders said they had been to a car auction, returning empty-handed.

The motorcyclists re-started their journey, but the cycle broke down just two junctions on.

On Monday, the Pakistan branch of the Taliban captured a supply convoy of thirteen trucks and two armored Humvees bound for NATO troops, without incurring a single fatality. They made off with millions of dollars worth of sophisticated military equipment, according to The Washington Post.

Approximately 60 masked militants belonging to Tehrik-i-Taliban blocked off part of a roadway in the Khyber Pass. The Taliban forces overran the Pakistani security forces, who were moving the shipment to an American military base, and briefly took the truck drivers prisoner. Although gunfire was exchanged, there were no casualties on either side. After releasing the drivers, the militants opened several captured cargo containers of wheat, distributing most of it to local residents.

The attack, which took place in the North-West Frontier Province, occurred several miles outside the border town of Jamrud. It was celebrated by the victorious fighters who photographed themselves with the captured equipment.

Pakistan’s federal government, which has recently stepped up efforts to contain the lawless tribal province, dispatched helicopters and 500 troops to try and track the hijacked convoy. One local child was killed, and four civilians wounded, by the gunships. The Taliban fighters were reported to have abandoned an American Jeep and one of the Humvees along the road, which were subsequently taken back into possession by Pakistani troops.

The Pakistani newspaper Dawn published a scathing editorial attacking the army’s incompetence and heavy-handed response to the embarrassing loss, referring to the attack as disturbing “both for its audacity and possible implications.”

Authorities in Indonesia initiated an investigation after a pornographic film was illicitly screened on a 24-square-meter (roughly 260-square-foot) LED billboard in the capital city of Jakarta on Friday, in full view of rush hour commuters.

The film, depicting a couple engaged in explicit sexual activity, appeared on the screen for several minutes — five, according to BBC News — during which time passerby took the opportunity to film the display and upload it onto the Internet. Following complaints to the South Jakarta Communications and Information Agency, authorities cut power to the billboard at about 2:45 p.m. to stop the screening.

According to a report on Saturday by Agence France-Presse, the film, identified as Japanese erotica titled Watch Tokyo Hot, was believed to have been transmitted to the billboard by a personal computer. Awi Setiyono, head of public relations for the police, said the investigative team for the incident includes a cyber crime unit, with the intention of determining whether the billboard was hacked.

Lestari Ady Wiryono, head of public information for South Jakarta, stated “The South Jakarta administration takes this matter seriously”. She said on Friday she had no information on the culprits or the source of the film. “We received the report and we immediately severed the electricity to there”, she said according to the Daily Mirror.

The billboard, located in close proximity to the office of the South Jakarta mayor, is owned by PT. Matapena Komunika Advertama, a private company, while content screened on it is the responsibility of PT. Transito Adiman Jati Transito Adverstising, according to The Jakarta Post. According to Lestari, following the incident, staff from her office along with the investigating cyber crime unit visited PT. Transito’s offices to gather information relating to the affected billboard.

The Indonesian government blocks access to pornographic websites in the country, whilst also subjecting scenes of romance in public broadcasts to heavy censorship. Under a 2015 decree, the government subjects content shown on billboards to standards of “public ethics, aesthetics, public order, decency, security and the environment”.

This year Israel turns sixty and it has embarked upon a campaign to celebrate its birthday. Along with technology writers for Slate, PC Magazine, USA Today, BusinessWeek, Aviation Weekly, Wikinews was invited by the America-Israel Friendship League and the Israeli Foreign Ministry to review Israel’s technology sector. It’s part of an effort to ‘re-brand the country’ to show America that there is more to Israel than the Palestinian conflict. On this trip we saw the people who gave us the Pentium processor and Instant Messaging. The schedule was hectic: 12-14 hours a day were spent doing everything from trips to the Weizmann Institute to dinner with Yossi Vardi.

On Thursday, the fifth day of the junket, David Saranga of the foreign ministry was able to arrange an exclusive interview for David Shankbone with the President of Israel, Nobel Peace Prize recipient Shimon Peres. For over an hour they spoke about Iranian politics, whether Israel is in danger of being side-lined in Middle Eastern importance because of Arab oil wealth, and his thoughts against those who say Israeli culture is in a state of decay.

	“The only crime I committed was to be a little bit ahead of time. And if this is the reason for being controversial, maybe the reason is better than the result.“

Shimon Peres spent his early days on kibbutz, a bygone socialist era of Israel. In 1953, at the age of 29, Peres became the youngest ever Director General of the Ministry of Defense. Forty years later it was Peres who secretly gave the green light for dialogue with Yassir Arafat, of the verboten Palestine Liberation Organization. It was still official Israeli policy to not speak with the PLO. Peres shares a Nobel Peace Prize with Yitzak Rabin and Arafat for orchestrating what eventually became the Oslo Accords. The “roadmap” that came out of Oslo remains the official Israeli (and American) policy for peace in the Palestinian conflict. Although the majority of Israeli people supported the plans, land for peace was met with a small but fiery resistance in Israel. For negotiating with Arafat, former Prime Minister Benjamin Netanyahu shouted at Peres, “You are worse than Chamberlain!” a reference to Hitler’s British appeaser. It was during this time of heated exchanges in the 1990s that Yitzhak Rabin was assassinated by Yigal Amir, a Jew who thought it against Halakhic law to give up land given by God (Hashem).

Peres is the elder statesman of Israeli politics, but he remembers that he has not always been as popular as he is today. “Popularity is like perfume: nice to smell, dangerous to drink,” said Peres. “You don’t drink it.” The search for popularity, he goes on to say, will kill a person who has an idea against the status quo.

Below is David Shankbone’s interview with Shimon Peres, the President of Israel.

Dima Bilan has won the 2008 Eurovision Song Contest, the 53rd, for Russia with his song Believe. The song was developed by US R&B artist Timbaland. The song won the competition with 272 points; 42 points ahead of Ukraine’s Ani Lorak in second place with 230 points for the song Shady Lady. Third was Kalomira for Greece with Secret Combination The voting for the competition came from 43 countries across Europe, but with 25 countries competing, the others having failed to get through the semi finals. Russia has never won the contest before, Bilan having come second in 2006, losing out to Finnish hard rock band Lordi with Hard Rock Halellujah.

Furtherdown the scale Germany’s No Angels with Disapear, Poland’s Isis Gee with For Life and the United Kingdom’s Andy Abraham with Even If came joint last with 14 points. Fourth last was Teräsbetoni, a Finnish heavy metal band performing in their native language with Missä Mihet Ratsastaa (Where Men Ride). Sweden’s Charlotte Perrelli had been predicted to repeat her 1999 victory, this time with Hero, but also received a low score.

There was an estimated 100 million television viewers from across Europe.

UK commentator Terry Wogan has garnered significant media attention for criticising the contest live towards the end of the broadcast for being overly political. “It’s a disappointment, considering that Andy Abraham gave, I think, the performance of his life with a song that certainly deserved more marks than it got when you look at the points that Spain got, that Bosnia-Herzegovina got – some really ridiculous songs,” he said. “You have to say that this is no longer a music contest… I have to decide whether we (himself and his producer, who already announced he wanted to leave) want to do this again. Western European participants have to decide whether they want to take part from here on in, because their prospects are poor.” He called the contest “political”.

Spain was represented by Rodolfo Chikilicuatre with Baila el Chiki Chiki (Dance the Chiki Chiki) and Bosnia and Herzegovina by Elvir Lakovi? Laka with Pokušaj (try).

Bilan, who received the maximum 12 points from Estonia, Latvia, Lithuania, Ukraine, Belarus and Armenia, all of which are former Soviet countries, was sent a telegram from Putin to congratulate him after his victory. Mevedev also contacted him later by phone to congratulate him. “Russia is the favorite now, it’s just tearing everybody up — in basketball, football, hockey, and Eurovision!” commented champion figure skater Evgeni Plushenko, who had joined Bilan onstage to skate as part of the winning performance. He is now also a politician.

Next year’s contest will be held in Russia.
