The presentation will focus mainly on different HTPC software (MythTV, XBMC, Boxee) and show the benefits and downsides of each one. I will talk about what other commercial options are out there Tivo and Moxi as well as look into media streamers such as the Roku, Boxee, Apple TV, Popbox and others. I will also show live demonstrations of some of the software so people can see it running first hand and see some of the features that set each one apart. We will go into why you would want to set up your own HTPC and what sources are available to you. (Hulu, Netflix, Revision 3). We can also touch on some hardware recommendations and good sources for help once you decide to build your own HTPC.

Modern system administration automates configuration management using state of the art tools. Here is an introduction to Cfengine, the open source configuration management tool with the longest track record, a large user base, and cutting edge features.

System administrators will take back to work an understanding of Cfengine 3 including it's syntax and benefits, and will be able to start using it.

Topics include:
* Moving from ad hoc administration to automation
* The importance of convergence and self-healing
* The Promise model
* Data types
* Quickstart configuration
* Example configurations and demos

UNIX and Linux sys admins have been using the GNU Screen utility for 25 years. While expert Screen users swear of its importance in their toolbox, the learning curve for new users can be quite steep. Enter 'Byobu', an innovative, intuitive approach to GNU Screen. The author of Byobu will introduce the basic flow of operation and also showcase the advanced features of Byobu and GNU Screen.

Data storage is just one element in the application delivery ecosystem, but it turns out that it is often the critical performance bottleneck. A number of new technologies have recently come to market that optimize storage performance. This session reviews several of these innovations and explains how performance-optimization technologies can be easily integrated into the existing storage infrastructure. Topics Include: * Understanding disk I/O patterns * SLC flash versus MLC flash versus DRAM * Packaging options for solid state storage * SQL database acceleration * MS Exchange acceleration * File system tiering acceleration * Dynamic tiered storage in a SAN array * Application-Level QoS * 3rd party caching appliances * Solid state storage and deduplication

The ever growing pool of neglected web applications is a breeding ground for malicious activity on the web, and is a concern for web hosting providers whose customers tend to leave no time for security updates after updating their blogs, forums or CMS sites. This talk will cover some basic information on 3 common attack methods as well a 3 easy ways system administrators can address each type of threat and some other details regarding security best practices. Attack: XSS, SQL Injection and insecure upload forms. Defense: mod_security, IDS/IPS (snort/snortsam), and file system monitoring.

This class will offer an explanation of important IT security concepts and practical examples of system hardening, access control, privilege management, intrusion detection, configuration/change management, firewalls, vulnerability management, and sensor/log monitoring. Beginners will learn how to start thinking about security and how to use some important tools that are available to them. Attendees with more experience will receive a refresher on risk-based security management while learning of some of the latest advances in Linux security tools.

MySQL 5.5 runs stronger, more reliably, and more efficiently than previous versions. This presentation covers many topics from semi-synchronous replication, scaling, and other improvements found in MySQL 5.5

When a server is used in production, you want every possible level of fault tolerance. Ethernet bonding allows you to create redundant NICs on a server so that you can lose a NIC, a ethernet cable, or even potentially a switch, without downtime. In this talk Kyle will introduce the concept of ethernet bonding, discuss the different bonding modes, and describe how to set up bonding on Red Hat and Debian-based systems.

This talk is a live version of a recurring Fedora Classroom session taught both online and in-person at classrooms as part of the first-day curriculum for POSSE (Professors' Open Source Summer Experience, a week-long cultural immersion workshop for university faculty looking to get their students involved in open source communities). The Unix design philosophy of modularity - simple parts that each do one thing well, connected by clean interfaces - applies to communication workflows as well as code ones. We'll give a live demonstration of how a collection of simple open source communication tools are used by the Fedora Project to coordinate thousands of technical and nontechnical contributions on a technically complex, rapidly moving, large-scale Linux distribution - all in a decentralized manner. Although each tool by itself is simple to learn and use, the magic comes in the interactions between these tools and the communication culture it makes possible in the communities that fluently use it. We'll go through both technology usage and cultural norms, with publicly available slides and resources for full tutorials and setup instructions for each tool available to all attendees by the start of the presentaion. We'll also explain how this ecosystem of tools can be deployed in your internal infrastructure and applied to communications within a school or industry team. Tools covered: * IRC: synchronous communication * supybot / IRC bots: synchronous context-bridging * etherpad: synchronous text editing * mediawiki: asynchronous text editing, documentation * ticket trackers: asynchronous task-tracking * blog planets: asynchronous context-providance * Classrooms: structures for synchronous community teaching

Whether you need a simple scalable development virtual machine environment or need to deploy a large cloud production environment, you need a tool that is easy to use, deploy, and maintain. Ganeti is a clustered virtual server management software tool built on top of existing virtualization technologies such as Xen or KVM. It is similar to libvirt in many aspects, but different in others such as its built-in cluster support using DRBD. The focus will be on a use case at the Oregon State University Open Source Lab (OSUOSL) where we were faced with scaling, performance, and reliability issues with our existing VM infrastructure. I’ll cover the overall design and features of Ganeti along with the basics of installing it. Additionally I’ll walk through some of the basic operations you may encounter (deployment, failover, expansion, hardware failures, etc). I'll also cover some tools that we are using to help manage our clusters.
