Presentations
SELinux has been around for a long time, but people are still confused by it. This talk will explain what the technology is doing, in simple terms using the SELinux coloring book.
I will then go on to explain the 4 things SELinux is trying to tell you and how you can modify your machine so the SELinux can be run in enforcing mode and your applications will be able to run more securely.
This talk is aimed at people curious about making the switch from hosting their own Postgres clusters to using Amazon's cloud solution.
Join Chris Van Tuin, Chief Technologist, West at Red Hat, as he walks through how OpenSCAP can help protect and secure the business.
Postgres is one of the most mature open source databases in existence, but that doesn't mean it can't keep up with modern data needs.
Come along on an adventure as we follow a request all the way through the web stack. You will catch a glimpse of the different startup and shutdown modes of PHP, figure out what the difference between mod_php and fpm are and learn other interesting tidbits of information as a request goes through its journey of being served.
Order matters when bash executes a command, but isn't strictly left to right. Redirects, functions, sub-shells, {brace,tilde,parameter,variable,arithmetic} expansion, pipes, globbing, regular expressions, command substitution and more.
What happens when and how does it affect other portions of the command? Which portions of the command line are evaluated by the shell and which aren't?
In this workshop attendees will learn about the Bigtop project, it's ecosystem and the roadmap for the project. They will receive an introduction to the concept of in-memory computing and learn about the Apache Ignite project. Attendees will also be given an overview of the Apache Spark project, a fast and general engine for big data processing. The workshop will conclude with sessions on how Apache Bigtop can be introduced into an existing infrastructure for those wishing to build their own stacks.
Vulnerabilities like Heartbleed and Shellshock have brought the security practices and track record of open-source projects into the spotlight. We will take closer look at security practices of projects and answer the question: Are open source security practices a fit for the cloud?
The barrage of recent publicity about automotive hacks has left the impression that the automotive cybersecurity problem is hopeless. Will security problems block autonomous driving from becoming a reality? Is security-through-obscurity inevitable? Linux offers a number of applicable features, but the real hope for a robust, affordable solution lies in a thoughtful architectural and network design. Linux can play a key role in secure automotive systems via its support for diverse hardware, virtualization and a large variety of network protocols.
A discussion of the various backup techniques available to PostgreSQL including pg_dump, pg_dumpall, pg_basebackup and other utilities. Includes information on creating your own backup scripts and detailed information on best practices usage for each utility.
