Interview

In advance of CloudOpen Europe 2014 (13.-15. October in Düsseldorf), it is an honor for me, to interview a well-known personality from the ranks of successful open source software companies. This is Frank Karlitschek, the founder of the much used and known cloud software ownCloud.

As an expert, he gives a helpful tips for data security in the cloud. Data security is still in the focus of public attention through the recently held minor and major scandals and leaks. We appreciate information about the roadmap of ownCloud and about goals the company has for the near future. Thus, the interview is not just interesting for techies, but for anyone who uses external data storage systems.

And. Yes, I did it, I restrained myself and didn’t told: The “why are you so great” question. Now I digress. Let’s get to the questions.

Interview with Frank Karlitschek

(Sorry the interview is in German. Please use the Translate button on the right. )

MLB: Herr Karlitschek, wie kann ich meine Daten sicher in der Cloud abspeichern?

Frank Karlitschek: Das ist ist keine einfach zu beantwortende Frage. Der Begriff “Cloud” wird in unterschiedlichen Zusammenhängen verwendet. Teilweise im Bereich Infrastruktur wie z.B. Amazon AWS oder für File Syncing wie Dropbox, Applikationen wie Facebook oder andere Webservices.

Tatsache ist, dass, falls Regierungen, Geheimdienste, White-Hat oder Black-Hat Hacker oder andere Personen die eigenen Daten finden wollen, dann werden sie vermutlich Mittel und Wege finden, dies zu tun. Das bedeutet aber nicht, dass man die Daten nicht so gut wie möglich schützen sollte. Schlieβlich schlieβen wir alle unser Auto und unsere Wohnung ab.

Wir müssen uns allerdings entscheiden, wie sicher wir unsere Daten schützen wollen. Ich habe ownCloud ursprünglich gegründet, da nicht jeder der File Sync und Sharing Dienste nutzen möchte, gleichzeitig mit den Terms of Services und Nutzungsbedingungen der Public Cloud Services einverstanden ist. Es muss eine Möglichkeit geben, die modernen Cloud Funktionen zu nutzen, ohne gleichzeitig die Kontrolle über die eigenen Daten sowie Privacy und Security abzugeben.

Es gibt heutzutage unterschiedlichste Möglichkeiten, Daten im Unternehmen oder auβerhalb des Unternehmen zu hosten. ownCloud unterstützt unterschiedliche Szenerien, sodass der IT Manager die optimale Architektur wählen kann.

Einige Empfehlungen für eine sichere Datenhaltung sind:

- Es müssen zwingend sichere Passwörter verwendet werden. Viele Data-Leaks der jüngsten Vergangenheit wurden durch unsichere Passwörter erst möglich.

- Dezentralisierung. Nicht alle wichtige Daten sollten an einer Stelle gehostet werden. Dezentralisierung insbesondere unter Berücksichtigung der verschiedenen Sicherheits- und Kostenaspekte ist wichtig.

- Moderne Cloud Technologien sollten verwendet werden, was nicht zwingend hosting “in the cloud” bedeuten muss. ownCloud unterstützt beispielsweise on-premise Technologien wie OpenStack oder off-premise Lösungen wie Amazon S3.

MLB: Was sind die nächsten Software Sprints von ownCloud?

Frank Karlitschek: Wir veranstalten 1-2 Entwicklertreffen pro Jahr. Der nächste Event ist für Anfang nächsten Jahres geplant.

MLB: Zur Roadmap von ownCloud: Was bringt der nächste große Entwicklungsschritt?

Frank Karlitschek: Unser Ziel ist ein 10X Wachstum in der nahen Zukunft. In Anbetracht unseren sehr schnellen Wachstums in den letzten 3 Jahren ist das kein unrealistisches Ziel. (https://owncloud.com/awesome-community)

Tux likes data security

Wir werden daran arbeiten, ownCloud noch einfacher für User benutzbar zu machen. Auf Enterprise Seite ist der nächste grosse Schritt “Universal File Access”.

In Organisationen liegen die Daten momentan hauptsächlich in Daten-Silos. Die Situation wird durch Consumer Public Cloud Services wie Dropbox und Google Drive noch verschlimmert. Es gibt hier groβe Security und Privacy Probleme.

OwnCloud wird die Möglichkeit bieten, auf alle Data zuzugreifen, unabhängig wo sie gespeichert sind. Gleichzeitig bleibt die volle Kontrolle über die Daten erhalten.

Die Daten müssen nicht verschoben werden und können in dem entsprechenden System gespeichert bleiben und müssen nicht dupliziert werden.

MLB: Bezüglich Embedded Systems: OwnCloud auf dem Rasperry Pi ist mit ein bisschen Gefrickel schon möglich. Planen Sie in Zukunft Hardware Produkte für Unternehmen oder Endkunden?

Frank Karlitschek: Das ist eine spannende Idee. Wir als ownCloud Inc. werden uns auf unsere Enterprise Produkte konzentrieren und wir beabsichtigen nicht, Hardware Produkte anzubieten.

Allerdings ist das ein spannendes Thema für die ownCloud Community. Auf der letzten ownCloud Contributor Conference in Berlin wurden verschiedene Möglichkeiten diskutiert, ownCloud in Router und andere Devices zu integrieren (http://owncloud.org/blog/owncloud-contributor-conference-was-awesome/). Je einfacher ownCloud zu installieren und zu betreiben ist, desto mehr User werden ownCloud verwenden.

MLB: Herr Karlitschek, vielen Dank für die ausführliche Beantwortung der Fragen und die wertvollen Tipps. Meine gewogenen Leser und ich wünschen Ihnen, auch im Interesse aller, weiterhin viel Erfolg mit ownCloud!

 

ownCloud – manage your atmosphere

ıllıllı  OwnCloud not only ensures the tightrope walk between ease of installation, rapid availability and the highest possible self-administration over the data streams. No one else decides about the size and performance of the data memory. Well, as long as nobody uses my .bvh Blender – Anim files against me, I still like cloudy storage. So: Private Server? Check! Linux client? Check! Android App? Great! Runs! Oh, Mr Karlitschek and ownCloud, why are you so great? ıllıllı

Cinelerra Linux Video Editor

The professional Linux Video Editor Cinelerra is now available in version 4.6. The annual update brings in the latest version 4.6 improvements in speed and stability. On the newly laid-out page of cinelerra.org the developers of Heroine are quite optimistic about the next steps of the famous video editing program Cinelerra and their plans for the nearer future.

Cinelerra with more Community

With the current campaign the developers announce a realignment of the Cinelerra project. The community should be increased and more involved.

Furthermore, they want to ensure a streamlined production process for professional video editing and keep the video editor run on different distributions. Especially with Ubuntu and CentOS versions cinelerra should run well.

Cinelerra is to remain for free. Nevertheless, they want to increase functionality and video effects.

Install and download Cinelerra 4.6

The current downloadable version is the source code of Cinelerra 4.6. This can be downloaded on the sourceforge page and can be compiled to all versions of Linux. A .DEB file for Ubuntu / Debian / Mint for easy installing Cinelerra 4.6 you can find here.

Cinelerra Features

Cinelerra 4.5 Linux Video Editor

Cinelerra 4.5 with Ubuntu

A few features and parameters of Cinelerra are listed here:

REAL TIME PROCESSING

Many effects are already visible, without having to render the video before

OPENGL

Cinelerra supports OpenGL on some NVidia graphics cards, which accelerate the playback and real-time rendering.

CODECS

Cinelerra supports codecs to import a large amount of video and audio. Most formats can be edited directly from the DVD, Blu-ray or original file, without transcoding. H.264 MPEG4 video + audio with Quicktime Container is the default export format.

RENDER FARM

For most applications, a modern computers is ok. To realize large projects faster, more computer systems come in a render farm quickly to the desired result.

Linux Video Editor mit neuer Basis

ıllıllı Cinelerra seems to be going to the right direction. The well-known video editor really requires a large base, not to lose the competing with products such as Lightworks. From easy-to-learn programs like OpenShot and Kdenlive to its far away. Currently still my favorite video editor.ıllıllı

Blender_-_logo_1

Again and again we hear good things about the in-house game engine of our estimated 3D raytracing and animation program Blender. Games like Yo Frankie!  are buildable with advanced knowledge.

Blender Linux Game Engine

Blender Game Engine mit Wasser Shader

Here is a short reference to the new  Blender 3D Video learning - series.

 

New Blender 3D video tutorial – series

If you want to know more about the Blender Game Engine, you are allowed to have a look at new video series about our 3D program. Using an example the Blender Game Engine and its possibilities were explained clearly. In the introductory game engine tutorial the multimedia specialist Gary Myers shows how to create with modeling, texturing and lighting a level of a building . Also, the game is made playable by adding game logic.

Have fun looking the tutorial videos!

The Blender Game Engine has not only the advantage of license freedom. Likewise, it is cross platform capabl, has sufficient real-time effects and performance for a variety of projects.

In the beginning, there is interest

Otherwise its definitely worth working with Blender 3D  . Short clips as the lower are created quickly, with a bit training and creativity. Blender is a Swiss Army knife for designers and with the many compositing options also become a useful tool for film makers now. For this, there are tons of tutorials and instructional videos. As a basis for working with the game engine, it definitely makes sense to deal with the basics of the main program.

Blender Game Engine project makes you want more

ıllıllı Even on older computer the engine is running very fast. Working with the Editor’s fun. I have a test basis added at the stage of two years ago, a couple of additional objects in a test demo, which were also displayed and reflected realistically in the digital water. Although just seems a bit static water without waves, it really looks for a real-time system very well. I’m excited to see what projects are still being developed with the Blender Game Engine in the future.ıllıllı

A few days ago the invitation to LinuxCon Europe 2014 and the Cloud Open Europe 2014 is purely fluttered to me. Well, purely fluttered, is well said. I was particularly pleased by a Tux muffin and for me insignificant Linux blogger the first invitation directly from the Linux Foundation to the major Linux event LinuxCon  and Cloud Open 2014.

Synergies and networking

This year’s LinuxCon will be combined with CloudOpen ELC Europe and various other technical events.  This results in more opportunities for training and cooperation.  That  is clear. Many different technologies and companies and finally the private benefit from the resulting synergies.

LinuxCon and CloudOpen in Düsseldorf

Here is the data of LinuxCon and OpenCloud.

LinuxCon 2014 / CloudOpen 2014

13. – 15. October

Kongress Zentrum / Convention Centre Düsseldorf

Why we can look forward to the LinuxCon 2014 and 2014 Open Cloud?

Why it is worth visiting LinuxCon and CloudOpen?

- Representatives of large well-known companies such as OwnCloud expressed in presentations to their current topics. Likewise, developers and project managers from the Linux community. Also, Linux creator and visionary Linus Torvalds  is represented. 

- Es gibt keine vergleichbare Veranstaltung in Europa, bei der sich Entwickler, Systemadministratoren, Systemarchitekten und technisches Fachpersonal mit unterschiedlichen Qualifikationen zwecks Bildung, Zusammenarbeit und Problemlösung unter einem Dach zusammenkommen

- There is no other event in Europe, which brings together developers, system administrators, system architects and technical staff with different qualifications for the purpose of education, collaboration and problem solving under one roof.

- Many products in the field of Embedded Linux development are shown.

- Cloud Open Europe offers technical content in terms of open cloud platforms only event at which join together various open cloud technologies under one roof AWS, Chef, CloudStack, Docker, Gluster, Hadoop, Juju, KVM, Linux, MariaDB, MySQL, OpenDaylight, OpenStack, oVirt, Puppet, SaltStack, Xen Project et al

So a mecca for Open Source and Linux enthusiasts.

More about the Linux Foundation

Who always wanted to know who or what is behind the Linux Foundation, must read the following:

“The Linux Foundation is a nonprofit association that is dedicated to the use of Linux and the collaborative software development. The organization, founded in 2000, supports the work of the Linux developer Linus Torvalds. It promotes, protects and improves the Linux operating system and collaborative software development, bringing together the resources of its members with those of the open source community.

Cloud Player für Linux

Store music in the cloud is a great thing. Space there is massive, even for free. For the favorite operating system you need now only a useful software that summarizes as much as possible  accounts to access quickly and easily a big amount of music.

Cloud Musik audio player in new version

Cloud Musik audio player in new version

The Nuvolaplayer is for Linux is a good choice. What I like, for example, is the automatic download of lyrics, and compatibility with many cloud services.

Cloud Musik from audio player everywhere

Nuvolaplayer handles Google Play Music, Amazon Cloud Player, 8tracks, Grooveshark, Hype Machine, Pandora, Rido. For example, Google Play offers the ability to manage up to 20 000 titles and the upload is free too.

Install Nuvolaplayer in Ubuntu

Although the developer of the cloud music player has stopped working, the player is still available for Ubuntu 13:10 Saucy, 13:04 Ubuntu, Ubuntu 12.04 via a PPA. Who already tried several times after an operating system update to install the Cloud Player, got a surprise. Despite correct installation steps not much happened. And in fact, its only working the “unstable” ppa Whether in the future it works with a stable thing. For me, the unstable works, installation and functions of the  Nuvolaplayer itself were correctly and without crashing.

The audio player supports multiple providers

The audio player supports multiple providers

Who wants to use the popular cloud player and is not afraid of the unstable ppa can simply enter the following commands in a terminal:

sudo add-apt-repository ppa:nuvola-player-builders/unstable

Then update the database with the command:

sudo apt-get update

Then simply install the player along with optional flash plugin with the following command.

sudo apt-get install nuvolaplayer nuvolaplayer-flashplugin

ıllıllı Of course there are web things for cloud music providers. However, rarely is the ability to access multiple providers in a short time and so on as much music as possible. Maybe a reader of the blog knows a good alternative for a player that supports multiple cloud providers? I’m Very open to suggestions. ıllıllı

Gimp 2.9

The Gimp people like to skip a version number of the known linux photo editor. Who wants to test the development version 2.9, can now have a look at the features of the 2.10 version.

GEGL / high bit depth 16 bit and Warp Transformtool

foto editor in version 2.9.1

Gimp foto editor in build 2.9.1

The major new feature in version 2.10 of the photo software is the complete support of GEGL / high bit depths. This means that finally 16bit and 32bit per color channel, both integer and floating support. This feature in the 2.9 is already active and can be tested. The new Warp Transform Tool also makes a very passable impression to me. The icon in the toolbar is like a spiral. It’s fun, so to correct images or just to beautify faces beyond recognition ;).

Install GIMP 2.9 (development build) in Ubuntu

Thorsten Stettin has created a new PPA for Ubuntu / Linux Mint users who want to use the latest GIMP 2.9 development builds. Version 2.9 is not officially stable version (for me it currently runs without limitations), to be published but can be fully utilized. Recommended such a limited version for production use. In the worst case, this installation could endanger the system. So here’s just a little warning to completion.

To install GIMP 2.9 in Ubuntu 14.04, 13.10 or 13.04, use the following commands:
sudo add-apt-repository ppa:otto-kesselgulasch/gimp-edge
sudo apt-get update
sudo apt-get install gimp

Back to the roots

If you want to go back to the stable GIMP version (purge the GIMP 2.9 development builds PPA and downgrade GIMP), use the following commands:
sudo apt-get install ppa-purge
sudo ppa-purge ppa:otto-kesselgulasch/gimp-edge

Blender 2.9

After three release candidates, the stable version of Blender 2.69 is now available for download. Blender 3D still relies more on GPU-assisted rendering, and has expanded its Cycles renderer optimized for it.

In addition to many new features over 270 bugs have been fixed in accordance with the previous developers. Similarly, the Sky-rendering has been improved so that users can simulate a creative yet enjoyable atmosphere.

Never run a changing 3D software?

3D software in newer version

3D software in newer version

Or was it the other way around ;). Well anyway, the Blender Guys think about users who will not want to install every few months a new version of Blender, but still want to benefit from bug fixes. So blender updates are now comparable to the Ubuntu updates a little bit. We will get Blender versions with the latest features and others with a kind of Longtime support for users who deal more with 3D rendering, then with updates and relearning new operations and possibilities .

With version 2.9 of the 3D program an improved import of FBX file format is now possible. Although is for animation for import not possible. In addition, the export in FBX format was expanded.

Blender realistic below the surface

3D Software

Subsurface scattering brings a more realistic design

Realistic surfaces were never a weak point in the 3D renderer. But you know, it’s always better. The so-called subsurface scattering calculated the light scattering. Within a surface of an object and generates the current issue of the 3D renderer using newer algorithms improved results.

With a little style from my blender

The rendering of hair has been simplified to use and fitted with improved effects. E.G. you can develop a realistic impression through reflective and translucent elements, which are realized through its own shader.

Cuts through everything!

Another interesting feature is the mesh bisection. Here, the body can be easily divided. The gaps that arise Blender simply filled with the surrounding data. Just around the properties of a workpiece to explain, maybe for industrial applications, this feature might be interesting.

Blender 2.9_2.jpg

The 3D software can more easily deal with hairs – Ok Tux, of course, has feathers;)

Here you can read the details of the new features. Or even better. You install it and start today with creative 3D design!

Blender continues to run on Windows, Mac OS X and Linux and is available in version 2.69 for download.

ıllıllı For many applications, the 3D software Blender is now at eye level with commercial software. Also, the operation and performance are on the right track.ıllıllı

lightworks

Since May this year, Lightworks for Linux can be tested by registered beta users. Anyway, the beta 11.1h, under Ubuntu 13:10 is very stable even with me. In the next few weeks, the public beta appears.

In December Lightworks for Linux 11.5 comes out along with the version of Windows. The MAC OS version programming is still in progress.

Lightworks 11.5 for linux

Einige der neuen Features für Lightworks 11.5 sind:

Lightworks Video Software für Linux

Lightworks 11.1H für Linux

Some of the new features are:
> AJA hardware I / O support
> Significant improvements sync group, including an automatically generated editing capability
> Direct youtube export out of the box
> Background export, so that users can continue working while running two edits / clips at the same time
> Screen Capture Recording
> Improvements to the user interface, including context menu

The new version is coming out as i said in december. The public beta of 11.5 should come out even in the next “few weeks”. It would if all goes well. Editshare comes to punctuality comparable to the GERMAN RAILWAY (Deutsche Bahn). So we aren’t in ever good hope ;).

Lightworks for linux download

If you want to test Lightworks for linux, you can sign up as a beta tester on lwks.com and download the. Deb file or click here to downloadit  now. there is a need to sign up anyway.

Lightworks is no lightweight for casual users. Therefore it is recommended to download and use some information to inform yourselve. The manual and the current Windows version you can find in the download section of EditShare.

Working like a professional

ıllıllı Hollywood for free. With Lightworks many blockbusters were cutted in the recent years. Who wants to try out this professional video editor, is invited to integrate the video software in their  workflow. More on that later.ıllıllı

Cinelerra Linux Video Editor

The estimated from semi to professional users Linux Video Editor Cinelerra is now available in version 4.5. The annual update brings like the latest version 4.4 improvements in speed and stability.

Keyframe transfer between audio and video

Besides, the programmers have improved the communication between audio tracks and video tracks using keyframes. Original sound: “Ability to transfer keyframes between audio and video tracks. “.The audio quality should be increased with speed changes of the video.

Install and download Cinelerra 4.5

The current downloadable version is the source code of Cinelerra 4.5. This can be downloaded on the sourceforge page and can be compiled to all versions of Linux. A .DEB file for Ubuntu / Debian / Mint for easy installing Cinelerra 4.5 you can find here.

Currently still my favorite editor, although I still like more the beta of Lightworks 11.1h. More on this later.ıllıllı
