This page is to share [[User:Rkr|my]] personal experiences of the '''[[LinuxCon]]''' Europe 2014.

== Background ==
Since the [[LinuxCon]] Europe 2014 was held in Düsseldorf, which is the location where I am working within the headquarter of Ericsson Germany, the chance was really unique to participate and to book a seat. I am a [[Linux]] and [[Open Source]] enthusiast since almost 20 years and - as solution architect - use these Open Source technologies as much as possible in my small area of customer projects and even exclusively in my private life. I strongly believe in the power of Open Source and the other "Open" trends within our society, like [[Open Data]].

The LinuxCon is not just for software and hardware developers, it's really a great event to get in touch with the Open Source community, with new information technology trends and with actual ways of working (agile methods like [[DevOps]]). It also covers things like making the most of communities and collaboration (also within your own company). And it even touches law topics and regulations (e.g. patents, licensing, IPR, ...).

About 2000 people attended and many global players but also smaller companies participated in giving key notes and providing speakers for the sessions.

== My schedule and experiences ==

=== Key Notes ===
[[File:Linuxcon_europe_2014_2.jpg|256px|thumbnail|right|Open Source collaboration skills]]
The key notes on all three days were related to common Linux and Open Source topics. My favorites were:

* [https://www.youtube.com/watch?v=dsdXWww3UqM State of Linux] - Jim Zemlin, The Linux Foundation
* [https://www.youtube.com/watch?v=S7OXlhPIVMY How Open Source Communities are Improving the Health of the Poor] - Paul Biondich, Founder and President of OpenMRS
* [https://www.youtube.com/watch?v=VzSJvA1RyJI Building Exponential Communities] - Jono Bacon, Senior Director of Community at XPRIZE
* [https://www.youtube.com/watch?v=tXlkaVnP_Hc The Service Enabling Wireless Network] - Anthony C. K. Soong, Chief Scientist for Wireless Research and Standards at Huawei Technologies Co. Ltd
* [https://www.youtube.com/watch?v=by_Cpp2KLAo Giving private clouds public capabilities] - Frank Karlitschek, [[ownCloud]]
* [https://www.youtube.com/watch?v=ZeMO0TvO4pU Alien Life Forms: Communities, Enterprises and All the Rest] - Olaf Kirch, Director SUSE Linux Enterprise
* [http://www.youtube.com/watch?v=8EUuaY6rh4o '''Linux: Where Are We Going'''] - Dirk Hohndel, Chief Linux and Open Source Technologist, Intel and Linus Torvalds, Fellow, The Linux Foundation (Video)

The most impressive key notes were from Jim Zemlin (Linux Foundation) and the talk with Linux Torvalds, of course. Jim's Conclusion: Open Source starts to dominate the complete ICT business. Jim also outlined a very important and valid list of skills, people and companies need to successfully collaborate on Open Source projects, see [[:File:Linuxcon_europe_2014_2.jpg|this slide]]. See also his quite similar speak at [https://www.youtube.com/watch?v=Xk32M7yyUnc LinuxCon North America 2014].

=== Sessions ===
After the key notes a lot of sessions were offered like workshops, presentations and round table discussions. Each of these sessions covered a certain topic of interest. There were even up to 6 or more sessions in parallel, so it was not even possible to attend to all interesting ones.

Main topics were grouped into:
*Linux kernel
*Cloud Computing
*Virtualization
*Container (LXC, Docker)
*Continous Integration (CI)
*DevOps
*Configuration Management
*Collaboration
*Open Source Communities
*Legal issues
*''... and more''

I '''attended''' to following sessions:
* Is SSH Really Secure? - Peter Tornberg, Fox Technologies
* Best Practices for MySQL High Availability - Colin Charles, SkySQL
* [http://events.linuxfoundation.org/sites/events/files/slides/LinuxCon%20Europe%202014-%20LXC%20and%20why%20system%20containers%20matter%20too.pdf LXC and Why System Containers Matter Too] - Stéphane Graber, Canonical Ltd.
* [http://events.linuxfoundation.org/sites/events/files/slides/gitlab-linuxcon-presentation.pdf GitLab as an Alternative Development Platform for Github.com] - Ralf Lang, B1 Systems GmbH

Well, two after-work '''community sessions''' need to be noticed here as well:
*Onsite Demo Reception & Booth Crawl: Some local [https://en.wikipedia.org/wiki/Altbier Altbier] and [https://en.wikipedia.org/wiki/Bratwurst Bratwurst] on Tuesday
*All-Attendee Reception: Food and drinks at the [https://www.nachtresidenz.de Nachtresidenz] on Wednesday

**Network interface mapping or just the complete networking environment,
 docker run -ti --net=host centos /bin/bash
**Add/Remove privileges
 --cap-add=NET_ADMIN centos /bin/bash ip add route ...
**Sysmonitoring with "oprofile" (stats about system usage, identify bottlenecks and processes using which resources,...)
**Root fs can' t be mounted, but workaround:
 -v /tgt:/mnt
**Systemd can also be touched
**easyDocker Tool

*Collaboration projects, OIN
**Business decisions important

== Conclusion ==
It was a great meeting with about 2000 people around the world and it was very much worth to participate in that event. The sessions gave a very good overview about the actual trends within the Linux and Open Source scene, which are going to dominate the ICT trends at all.
