ownCloud 5 released: a vision realized, a vision expanded

Posted by on Mar 14, 2013 in ownCloud | 5 Comments
Today we released ownCloud 5, a very important milestone for the ownCloud community and perhaps the most important release so far. But before going into the details I want to take a step back and look at what the original idea of ownCloud was at the beginning.
The idea of ownCloud was and is to enable everybody to host, control and sync and share their personal data without giving control away to the big data silos like Dropbox, Google Drive, Skydrive and iCloud. I think today we have all the features in place to say that we reached this goal. Everybody from a home user to a big enterprise can host their own personal cloud installation. I’m also super happy about the integration into KDE and GNOME because this is important to provide a really seamless experience for users.
It’s a coincidence that CERN invited me to give a talk about ownCloud and data silos that I will give here in a few hours at the exact same day ownCloud 5 is released. CERN is also the place where Tim Berners-Lee invented the World Wide Web 22 years ago. It’s interesting that the Web was built as a completely decentralized system where no distinction between someone who is publishing data and someone who is consuming data exists. There is no concept of a centralized entity that everybody connects to. Everybody can be sender and receiver at the same time. Just as Berthold Brecht proposed in 1932.
Interestingly, the web looks a bit different today where a huge amount of the traffic goes through websites like Facebook, Google, Dropbox and Amazon. Where is the idea of a decentralized and federated web?
Today we are deciding how the world will look like in the future. We, the IT community, set the course of the train that is called “open society” now and we can decide into which station the train will roll into in 5-10 years. Is it the one where all the people still control their own data and information and can decide who has access to the personal files, photos, contacts, location data, chat messages and other personal information or will we live in a future where all the personal data of all the people in the world are stored on the servers of just a few big organizations and commercial interests, terms of services and secret services decide who has access to the digital life of everybody?
If you care about these questions then join the ownCloud community or other free software projects and work on decentralized and federated alternatives.
ownCloud 5 is the result of the work of our awesome developer community. More and more people join and are getting more involved. To me this is a sign that we are doing something right and that ownCloud is not just a crazy idea that no one needs but something that is very important to a lot of people.
We did 2 major developer meeting during the development of ownCloud 5. One in Berlin and Ann Arbor in parallel last fall to do most of the ground work. And one just a few week ago in Stuttgart to really streamline and polish ownCloud 5. We will do the next developer meeting in a few month and
everybody is welcome.
ownCloud 5 is also proof that a company and an open source community can work together on a product in a very open and effective way. It is needed of course that both parties have a shared interest in the success of a product and that the development happens in the open. But I must say that I’m proud that we managed to set this up in a way that works very well.
We added a ton of cool new features in ownCloud 5. The features are interesting enough so that they deserve a blog post on their own. So tomorrow I will blog about the new ownCloud 5 features. But as important as the new features are three other things:
A lot of work to improve the quality of ownCloud went into the version 5. We launched a quality imitative during our developer meeting last fall. We introduced peer reviews for all commits that go into the core. We launched a new documentation system that has great new docs for users, administrators but also developers. We have improved application templates and sample code to help newcomers, we launched a new Jenkins-based continuous integration testing imitative with a lot of tests. We switched to a new and better bugtracker and provide daily builds of the server and the clients. This all
helped us to increase the quality of ownCloud 5 significantly.
I’m so proud that we have a top notch security team at ownCloud. We have a state-of-the-art workflow when someone reports a security problem to us – including a responsible disclosure policy, publishing bugfix releases quickly and releasing advisories on our website. In ownCloud 5 we also added a few significant security enhancements including better CSRF checks, improved data sanitization and we disabled inline Javascript to prevent XSS bugs.
A lot of work went into ownCloud 5 to improve the overall performance. One of the key components is our filesystem cache and abstraction layer. This was completely rewritten to improve the performance significantly. Some tests show up to 500% faster performance compared with ownCloud 4.5. if you work with a lot of files or you have a server with a lot of users. We also looked into the overall database structure and optimized it for big installations. The sync protocol was also improved to reduce the roundtrips between the clients and the server to sync faster.
ownCloud can be downloaded here: [owncloud.org] There will me release parties in Berlin and Stuttgart including, talks from developers, on friday. So please join us if you are interested: [events]
Thanks a lot to everybody who made this release possible. You guys rock.

    I really like the idea of Owncloud. What I like is the idea of having the control over my data. Unfortunately I am not able to maintain my own server. I guess if I would do it, it would be hacked very soon. But I also believe that just renting Owncloud service would be similar to use Dropbox. So the best would be, if there would be a kind of Owncloud box where I could plugin harddrives with an autoupdating firmware which I could plugin in at home.
    Is there any Owncloud box in planing?

    I believe you can get fairly easy home server with a Sheeva/Plug-PC what you just attach to power socket, then attach it to network (wireless or wire, depending Plug-PC) and attach your wanted USB-sticks or USB HDD and then you open the device manager from local network and configure it.

    If OwnCloud would come easily installable to any Plug-PC (many models has great big communities) as most (if not all) already offers some of Linux distributions in them, it should be fairly easy to get it working.

    Example first ones http://www.geeky-gadgets.com/marvell-sheevaplug-tiny-linux-power-plug-pc/

    More information of some models what Debian supports: http://www.cyrius.com/debian/kirkwood/sheevaplug/plugs.html

    But if we could just get official OwnCloud image installed to USB stick and then installed to such computers, it would be “perfect”.

    I am aware of those kind of plug solutions. But as far as I know it would require me to replace the firmware with a Linux installation of my own. So the difference between maintaining a server somewhere else and this solution would not be very big difference in the sense of security. It would be cool to have a box which would only be running owncloud and may be a Firefox-Sync-server with a self-updating firmware.

    @mark-wege: I don’t think someone from ownCloud plans to build an ownCloud box. But it’s free software and everybody is free to do it. So let’s hope and see 🙂

    I love ownCloud, both the idea and the implementation. Installing it on Mint/Ubuntu is a breeze, and accessing it from the web or a Linux file manager is quite easy.

    HOWEVER, accessing it from a Windows machine is a royal pain. Windows seems to hate WebDAV, or me, or both. It’s not ownCloud’s fault, probably, but it’s incredibly unfortunate that the solution (a local cloud with ownCloud) that we wanted to implement in our company will be dumped just because we found no way to connect to it from Windows (95% of our users).
