In this presentation, we’ll get to know Git intimately enough to
anticipate its every move. We’ll develop a visual mental model for a
Git repository. Then we’ll explore how every-day Git commands
manipulate that model. Along the way, we’ll find ways to peek into
Git’s inner world to confirm our understanding. This is not an
introduction to Git; it targets a developer who can commit, branch,
and merge with Git. Although I’ll show example commands and output,
consider bringing a laptop with Git installed so you can type along.
Have you ever been asked to provide feedback on beta software? If so,
you’ve been put in the role of a tester, and effectively communicating
what you see when things aren’t working the way you expect them to can
be challenging. In this talk Allan will cover the context-driven
approach to testing with an emphasis on how to troubleshoot problems,
how to report what you see in the most effective manner, and how to
know when it’s time to stop testing an area and focus your time elsewhere.
Server security is more important now than ever, yet many of the hardening
guides out there read like they were written a decade ago (probably because
they were!) Modern server hardening can be an obscure and complicated
subject but it doesn’t have to be. There are a number of simple and
fast-to-implement steps you can take to dramatically increase the security
of your infrastructure. In this talk Kyle will start with an overview of
security best practices and provide a series of current yet simple
hardening examples effective for securing everything from traditional
bare-metal networks, cloud infrastructure, and even your home network.
Midokura released Midonet under the Apache license in 2014. This talk will explain why Midokura released the software under an open source license and why it picked Apache. In order to understand the options, the business models used with GPL and Apache will be discussed, which will include comparing the rights granted under the two licenses. Midonet will also be explained, at a very high level, to provide context for the decision to make it open source. Please note that this talk should not be construed as legal advice.
The NBLUG elections will be held directly following the talk. A nominations E-Mail will be sent to the talk list with additional information.
In this talk, Greg Larkin, an engineer with Puppet Labs, will discuss some of the historical issues with system management, how Puppet works, how it fits into current types of infrastructure deployments and what some of its enterprise features are. The talk will touch on high-level concepts as well as show some code and how it enforces node configurations. The talk will also cover new Puppet developments that were recently announced during PuppetConf 2015.
While Linux users have spent a lot of time using free software on their
computers, usually that stops at the operating system. Being able to view
and modify your source code not only gives you more freedom, it gives you
more security, in particular from back doors. What’s good for the OS is
good for the BIOS, which malware hackers, Lenovo, and state-sponsored
attackers have all used to persist their exploits.
In this talk Kyle will cover Libreboot, a completely free software
distribution of the open source Coreboot BIOS and discuss the current state
of hardware support for Libreboot and how to install it, including a brief
description of how to turn a Raspberry Pi into a flashrom BIOS-flashing platform.
In this talk, Nick Bolton will describe how he took a largely abandoned open source project (Synergy) and grew a stable and profitable business around the software. The talk will cover the impact that money had on the technology, the users, and the developer community.
There is general concensus that systemd is an important topic but we haven’t found a speaker to specifically present on systemd so instead we’ll be doing a systemd roundtable. The format will be a friendly discussion about the pros and cons of systemd and its political and technical impact on distributions that have migrated to it for the enlightenment of all. I’ll bring the projector along just in case someone needs it.
OpenStack is a set of tools to create a “cloud” infrastructure similar to Amazon’s cloud services to manage virtual machines (called instances) across multiple Compute servers in a cluster managed by one or more Controllers. In this talk I’ll introduce the general concepts of what OpenStack can be used for in an approachable way. I’ll provide an overview OpenStack’s Controller and Compute node model, how instances work, block and image storage, and a general overview of bridged networking into virtual machines. The majority of the talk will be devoted to a live demo of spinning up instances with plenty of time for interactive Q and A.
