The North Bay Linux Users Group is a computer users serving the San Francisco North Bay and surrounding areas.
We strive to promote Linux, Free Software, Open Source, open standards, and to generally have a good time by hosting social events that educate, allow members to share ideas and knowledge and to build friendships.
We hold regular meetings on the second Tuesday of each month with a selected topic presented by a guest speaker.
Meetings and membership are free and open to the public.
Please sign up for the announce mailing list to receive notifications of upcoming events, or join us on the talk mailing list or in IRC to get help with Linux.
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.
Window management: it’s one of the places where desktop Linux shines,
with an almost overwhelming amount of choice for a newcomer. For those
wishing to improve their day-to-day productivity or stop reaching for
the mouse all the time, however, venturing into this world is well
worthwhile. This talk will provide an overview of the landscape,
details on the tiling window manager i3, and some tips on setting up a
In this talk, Jordan Erickson will show you how to build your own online radio station using the open source software Icecast.
The talk will include installation and configuration of Icecast and compatible source clients, as well as examples of different listening clients.
There will also be discussion around Jordan’s efforts in creating a new Android source client that focuses on open codecs and a Creative Commons broadcast network called Echonet.
Linux bridging is one of the seven mysteries of Linux.
What is the br0 device and how does it use the NIC?
What is virbr0?
The answers to these and many other questions will be answered including how virtual instance use bridges and how they interact with the host’s IPtables.
The goal of this talk is to give the Linux Sysadmin the understanding needed to configure, use and trouble-shoot Linux bridges.
Robert Harker is a [Linux|UNIX] greybeard sysadmin and one of the first Sun sysadmins.
His interests include OS/application configuration management of scaling of server farms with a particular interest in verification of deployments: “How do you know it is correct and running?”
This talk is all about dissecting exactly what happens when a program stops doing what the designers designed it to do and starts doing what an attacker (or in this case, the presenter) wants it to do.
I’ll cover using a virtual machine environment of a simple system under Linux to step through all phases of an arbitrary code execution (ACE) exploit, including corrupting a data structure, out-of-bounds memory manipulation, pointer manipulation, and ultimately execution of arbitrary code.
I’ll be demonstrating memory viewer and disassembly tools to show the exact instructions being processed as they happen.
The simple system in question?
A Zilog Z80 processor, running inside of a Super Game Boy.
Come for the dissection, stay for some entertaining abuse of a live SNES console.
This will largely be a no slides, full demo presentation and should have something of interest for everyone.
See you there!
It’s easy to secure your servers when they are in the safe confines of your
own data center, but deploying servers in the cloud is like dropping them
from a helicopter into a jungle across enemy lines without so much as an IP
address. This talk will cover how to use Puppet to harden cloud servers
including certificate and key management, protecting secrets on your hosts,
managing dynamic IPs, and overall security best practices. While a few tips
will be specific to Puppet and Amazon AWS, most of the techniques would
apply in just about any environment.
I just spent the last 2 days at Agile Open Northern California.
This talk has nothing to do with Linux directly.
I intend to talk some about the sessions I attended, but more about the concept of Open Conferences in general.
The presentation will be followed by nominations for NBLUG’s upcoming elections and discussion of this month’s developments: shellshock, etc.
All positions are up for election and are listed in the bylaws.
I will give a brief talk about how we used a modified Pocket Radar unit, a Raspberry Pi board, and an HDTV to implement a radar speed sign.
The talk will include a brief overview of how the Pocket Radar works and what modifications were done to interface it to the Raspberry Pi.
In addition, I’ll explain a little about the webpage development and how it is run on the Raspberry Pi.
Also, I’ll cover what software was used on the Raspberry Pi, along with what configuration file changes where done.
I will bring a demo system so that people can see the sign in operation.
