Not all servers and services do "operate within normal parameters" all 		 the time. If they don't, system engineers need reliable procedures to 		 track and fix problems. In this track, LinuxTag speakers explore tools 		 and techniques to trace programs, to profile applications, to monitor 		 and enhance database connections, and web scripting language 		 frameworks. They learn how to manage and aggregate aquired data, skim 		 it for values and events that make information from data.
A list of tools and projects might include but is not limited to 		 Strace, Ltrace, Sviz, Breeze, New Relic, Dtrace, features of JBoss, 		 Log4j, Logstash, Splunk, Graphite, Syslog-NG, and monitoring 		 frameworks.
Action is due after a couple of months lamenting about security and 	 	 privacy breaches inflicted by intelligence agencies and major Internet 		 corporations. Who, if not users and administrators of open source 		 systems, has the option to protect oneself from eavesdropping and 		 surveillance?
Adding to that, protecting infrastructure from competition and 		 miscreants is essentials. Conference delegates learn what to do to 		 effectively protect their privacy, take measures against surveillance 		 and how to judge the effectiveness of security tools and ciphers. Last 		 but not least they discover strategies to spread the word in order to 		 curb the silly "I have nothing to hide" error in reasoning.
A list of tools and projects might include but is not limited to 		 OpenSSL, OpenSSH, Tor, GPG, and other security related tools.
Linux reached a next level in the gaming industry with the advent 		 of commercial grade gaming platforms based on open source 		 software. LinuxTag visitors are interested in design decisions, 		 technology choices, and ways to participate in the ever growing field 		 of entertainment development. Libraries and frameworks support 		 developers to code for high framerate, animated and networked pastime 		 experiences.
A list of tools and projects might include but is not limited to 		 all kinds of game platforms and development environments.
Virtualization manifolded the number of servers administrators take 	 	 care of. The need to orchestrate your services, automate configuration 		 and deployment processes gave birth to many frameworks that act as a 		 helping hand. Provisioning of a stage environment is just a matter of 		 seconds.
Most share a common set of functions but some tools are better 		 suited in situations compared to others. Conference vistors learn in 		 this track how these platforms work. They want to identify specific 		 advantages and discover best practises for configuration management, 		 software deployment, and virtualization provided by experienced 		 experts.
A list of tools and projects might include but is not limited to 		 Puppet, Chef, Saltstack, Fabric, Ansible, Vagrant, Rex, Jenkins, 		 Docker, and Cfengine. IaaS management may cover Open Stack, 		 Eucalyptus, Ganeti, Cloudstack, OpenNebula, OpenQRM, VMware, and EC2.
Home gardening and power knitting appear to be popular retro 		 trends: Folks recollect traditional virtues. This applies also to 		 computers: In the aftermath of Prism and Tempora like the idea to have 	 	 more control over servers and services. In this track, delegates learn 		 how to set up a fileserver, receive own mail, launch a blog, maintain 		 a web server, and host a personal web shop to sell the knitted 		 socks. They train their skills in hardening, to configure a firewall 		 and email encryption, and finally set up a Tor server.
In a more advanced approach, developers build their own devices, 		 appliances, and even networks: SDN build complex network segments, and 	 	 compose experimental protocols. By means of SDR programmable network 	 	 chipsets even allow to create own broadcast applications.
A list of tools and projects might include but is not limited to 		 Owncloud, postfix, exim, sendmail, wordpress, dyn-DNS, webshops, 		 apache, nginx, hardening, mod_security, firewalls, netfilter, 		 nftables, Tor, GPG, Enigmail, OpenWRT, Freifunk, OpenVSwitch, and Open 	 	 Flow.
Extracting information from collected data in a fast way is a key 		 goal to keep your business running. When once data retrieval was 		 accomplished in the uniform way of speaking SQL, today there are 		 several approaches like full text search, object stores and key value 		 tables. Attendees of this track learn about the advantages and 		 pitfalls of storage engines, NoSQL databases and search indices. Big 		 data requires even new programming paradigms and blur the boundaries 		 between databases and file systems.
A list of tools and projects might include but is not limited to 		 MongoDB, Elastic Search, Redis, Hadoop, Cassandra, Swift, Ceph, Solr, 		 Lucene, Map Reduce, HDFS, and Hadoop.
Running a successful website is fun, but not all webmasters are 		 prepared to get slashdotted or ddosed. This track tells to benchmark 		 the performance of a site, to measure its thoughput, to evaluate it 		 concerning accessibility, and scan for security 		 vulnerabilities. Frameworks help webmasters to optimize their UI, do 		 A/B testing, replay user requests, and run complex test suites before 		 you deploy. New generation browsers facilitate clientside applications 		 by means of websockets and stream with Web RTC.
A list of tools, techniques, and projects might include but is not 		 limited to Apache Bench, Jmeter, Apache, Nginx, Firefox, Chrome, 		 Opera, Node.js, angular.js, amber.js, backbone.js, GWT, OWASP, 		 Mod_security, skipfish, pagespeed, Firebug, Ghost, Selenium, and robot 	 	 framework.
Building complex software products for customers is 		 an difficult task, where the traditional approach to 		 software development often is too risky, more costly 		 and less efficient. An essential shift in the way 		 how software is developed, tested, deployed, and 		 improved is widely discussed by software developers, 		 system engineers, and product managers. Developing 		 software with lean and agile methods focuses on 		 implementing features, which are small, 		 fully-tested, independent and valualable.
In theory agile methods like the Scrum framework are easy to understand and simple to use. But experience shows that turning an organisation from a waterfall approach to agile practices is more than sorely a technical task, where developers learn about pair-programming, TDD or continuous integration. It is also about self-responsible and crossfunctional teams, leaving behind traditional roles and cultural change in organisations. Agile methods strive to narrow the classical gap between operations and development. This track investigates the impact of such approaches to software development in general and Open Source in specific.
A list of tools, techniques, and projects might 		 include but is not limited to continous integration, 		 lean development, Scrum, Kanban, and DevOps.
OpenStack is a complete cloud solution that was built to simplify IT vendors' business, as far as it didn't take off into cloud computing yet. Unlike other cloud solutions, OpenStack has deep roots in the FOSS community and is supported by many companies and developers. The track will guide through the OpenStack universe, show use cases and feature other projets, that come in handy in cooperating with OpenStack.
 A list of tools and projects might include but is not limited to OpenStack components like Nova, Swift, Glance, and Cinder, as well as augmenting technologies like Ceph, cluster file systems, or software defined networks.
Deadlines and conditions
Apart from the listed main topics, LinuxTag gladly also accepts any other proposals for talks and presentations until Friday, February 7, 2014 in its virtual Conference Center (vCC).
