Michael Dexter from Linux Fund/BSD Fund will give his EuroBSDCon 2008 presentation:

Zen and the Art of Multiplicity Maintenance: An applied survey of BSD-licensed multiplicity strategies from chroot to mult.

Topics of this survey include chroot, jails, Xen, sysjail, SIMH, NetBSD/usermode, kauth Jail, QEMU/kQEMU, GXemul, vkernel

  Given that the database, as the canonical repository of data, 
 is the most important part of many applications, why is it 
 that we don't write database unit tests? This talk promotes 
 the practice of implementing tests to directly test the 
 schema, storage, and functionality of databases.

 David E. Wheeler, Founder of Kineticode and Co-Founder of 
 PostgreSQL Experts hacks Perl, PostgreSQL, JavaScript, and Ruby. 
 I believe David is also the lead developer and maintainer 
 Bricolage which is a well known CMS. 
 David lives in Portland.

Using DRBD to Build High-Availability Clusters on Commodity Hardware

Charlie Schluting of LINBIT will explain how DRBD works and how people currently use it, with enough information to get you started building your own clusters.

DRBD stands for Distributed Replicated Block Device, and as the name implies, allows you to replicate block devices over TCP. DRBD is extremely flexible due to the fact it is a block device, and as such is used in a variety of situations. At the most basic level, you can replicate data between two servers to provide synchronously replicated storage redundancy for either failover or disaster recovery purposes. In active/active mode, you can also run GFS, OCFS2, or other clustered file systems.

Topics that will be covered: - How it works, history, and future exciting news regarding mainline kernel inclusion - How it is used: HA-iSCSI, HA-NFS, Virtualization, Apache, Samba, etc. - Cluster Resource Manager options and recommendations, and news about the confusing changes in the Linux-HA / Clusterlabs communities.

And the majority of the time will be spent on: - Example cluster configuration: hardware setup, installation and configuration, and cluster manager integration.

Come with questions!

                         What is it Good For?

 Drupal is growing leaps and bounds these days, powering everything 
 from ma and pa brochure sites to Obama’s recovery.gov. Does this 
 mean it’s a great fit for any website? Not exactly.

 Drupal has been defined as many things, including a content 
 management system, a web application framework, and community 
 plumbing. In some ways, this is both a blessing and a curse; 
 there’s so much you can do, in so many different ways, that new 
 users are crushed under the weight of the options and lack of 
 clarity. In addition, all of that flexibility does come with a cost, 
 in terms of performance and conciseness.

 This presentation will cover some Drupal basics including history, 
 core concepts, and system structure. From there, we will dig into 
 Drupal’s strengths and weaknesses, finishing off by discussing the 
 types of projects Drupal is best suited for, including specific 
 examples for each case.

 My hope is that developers new to the platform will gain a better 
 understanding of when to approach a new project with Drupal, more 
 experienced developers will gain a bit of insight on when not to 
 use it, and non-techies will have some help in choosing a platform 
 for their projects along with an understanding why developers they 
 work with select a given platform. Please note that this talk will 
 not delve deeply into the technical details of Drupal.

WARNING!!!

Jeri is sick and can't do the talk tonight.

Informal DorkBotPDX demo night instead!

In place of Jeri, I have some offers to do demos of projects from DorkBotPDX land, including Simran Gleason about his Kepler's Orrery (a generative music system that composes music from gravity equations), I have a little stepper motor demo, someone suggested they could demo Luz (a ruby / opengl 4-d drawing software), and there may be others.

Brian Martin will be test-driving his IEEE presentation on his experiences in a true, "abandon the building" disaster recovery effort. He'll place particular emphasis on where technically sound, well-tested disaster plans often fail in a real disaster, and how these problems can be overcome.

The best data center disaster recovery plans are developed carefully and tested regularly. If you're at that stage, you may think you are well prepared. In this entertaining presentation, Brian Martin describes the unexpected problems that arose when a well thought out and tested plan met a real disaster, and draws lessons that are applicable to any disaster recovery situation.

Brian Martin has spent 30 years in the IT field, fairly evenly divided between being a mainframe system programmer and a server system administrator. He has operated Martin Consulting Services in the Portland Oregon area since moving to Portland from the San Francisco Bay Area in 1996. He has a wife, two cats, a dog, and nine in-service computers at home.

DRBD stands for Distributed Replicated Block Device. Mainline in the Linux kernel since 2.6.33, it is used to replicate data at the block level over the network in a "network RAID1" fashion. It is generally deployed as a cost effective, shared-nothing alternative to a SAN and used as the building block for high availability clusters. Pacemaker is currently the de facto open-source cluster resource manager (CRM) for Linux HA clustering. With it, nodes and services can be monitored and managed to ensure maximum uptime in the face of the most severe service and hardware level failures. Combining the two allows admins to %99.999 uptime at a fraction of the price of proprietary alternatives.

In LINBIT's second PLUG Advance Topics installment, Adam Gandelman will give a more in-depth view of DRBD and Pacemaker and demonstrate how they work closely together to keep applications running and consistent. During the second half of the presentation, Adam will provide attendees with a real-world example by configuring a highly-available LAMP cluster from the ground up. Though geared toward web services, the concepts presented can easily be expanded to provide the HA gaurantee to virtually any Linux service.

Agenda: - Brief re-introduction to DRBD, Pacemaker and HA clustering concepts. - Overview of various use cases and interesting deployments - Configuration and implementation of a highly-available LAMP cluster using DRBD for data redundancy and Pacemaker for resource management.

Adam Gandelman is an expert in open-source clustering and high availability. Originally from New England, Adam lives in Portland, OR where he has been working at LINBIT, developers of DRBD and maintainers of Heartbeat. Aside from providing top-level Linux High-Availability and Disaster Recovery consulting for customers in the Americas, he leads LINBIT training courses in the US, doubles as a technical writer and regularly contributes to related open-source projects.

                             Presentation
                    Open Source Desktop Publishing
                                 with
                               Scribus

                                  by

                          John Jason Jordan

 Scribus is just a few years old, but has already achieved 
 most of the features of the expensive commercial desktop 
 publishing apps, and a few they don't have. If you need to 
 do fliers, brochures, or whole books, Scribus is now the 
 preferred tool.

 The presentation will start with a brief introduction to 
 some of the terms of desktop publishing, especially how to 
 get your computer to produce something that a print shop can 
 put on a press. This will include matters such as typography, 
 color management, banding and line screens, transparency, 
 imposition, and several other issues.

 Then we will spend a few minutes on an overview of Scribus, 
 how it is different from word processors, TeX, and advantages 
 and disadvantages.  This will include the basic features of 
 Scribus, including typographical controls, master pages, render 
 frames, PDF forms, PDF export options, scripting, collect for 
 output, and lots more. It will also cover how Scribus is the 
 end tool in a process that starts with other programs.

 Finally we will reproduce the PLUG flier that was created 
 in Scribus.  This will be presented on the screen showing 
 the steps and features of Scribus necessary to produce it. 
 Each member of the audience will have a paper copy of the 
 flier to assist in following the process.

                           hopefully others


 Daniel Hedlund will give a little ad hoc mini-demo on 
 setting up a VPS on Linode.com.

 David Mandel will discuss a couple ways of using virtualbox
 in a teaching environment.

 We invite others to join in with their own short little 
 mini-presentations on simple little "hacks" that you find
 useful.

Cooper Stevenson is rescheduled to give his talk: Artificial Neural Networks: Principles and Applications

Cooper will cover how the topic is relevant to Open Source as ANN's may be used for a host of practical applications and serve as an introduction to ANN's running on Open Source.

Emphasis will be placed on the financial industry's use of ANN's for market prediction but other uses will be addressed.

Cooper Stevenson's Bio: Cooper is a leading expert in Information Technology systems for business automation.

                             David Mandel


 David Mandel is interested in distilling the core ideas 
 from the philosophy of Open Source Software and extending
 these into other areas like music, publishing, farming, 
 and education.  In the past he has given presentations
 on Open Source Agriculture.

 In this presentation, David wants to discuss Open Source
 in education.  This is not a presentation about using 
 Open Source Software in traditional classrooms as much
 as it is a discussion about using Open Source Philosophy
 to change traditional classrooms.  We will discuss the 
 work of John Gatto author of "Dumbing Us Down", the Moore 
 Method of teaching mathematics, and David Mandel's personal 
 experience teaching mathematics and computer classes in 
 community colleges.

February PLUG Advanced Topics

BSD (Berkley Software Distribution): Enterprise Open Source From Day One

W&W: Tuesday, February 15th, 7PM at Free Geek, 1731 SE 10th Ave

Synopsis:

You use BSD software every day.

Virtually every packet you send travels through BSD-based routers.

BSD gave us the Internet, which gave us Linux and the FLOSS revolution.

The iPhone contains BSD software. OpenSSH is a BSD project.

Michael Dexter of BSD Fund will give a tour of how BSD is being used and discuss why it happily lurks in the shadows of open source. BSD myths will be addressed along with an open discussion of what the audience is doing with BSD.

Presentation Free Content and the Data Revolution by Daniel Hedlund

The amount of information available on the Internet has exploded in recent years and shows no sign of slowing down. Most of this information is freely available to anyone with a web browser --- but what does free mean? Daniel Hedlund will lead a discussion on the meaning of open data and explore how the open source movement is no longer constrained to the realm of software.

IPv6 Networking with Ted Mittelstaedt: Part 1

The first in a multi-part series on IPv6 networking by Ted Mittelstaedt, the author of The FreeBSD Corporate Networker's Guide.

Part 1: Theory & management & ISP routing, as well as current events in the IPv6 realm. For example, did you know that Nortel just sold Microsoft a huge chunk of IPv4 legacy addresses for something like 7 million dollars? This has really turned the tables on the game. Up until that happened the thought in the community was that the large ISP's would be the biggest pushers of IPv6 deployment. But this is an early indicator of what's going to happen. The large ISPs are going to spend millions in vacuuming every scrap of IPv4 out of all the corners on the Internet before they will start pushing their users to go to IPv6. That is a serious problem for any small ISP that does not have a stock of IPv4 because they will be run out of numbers and new customers will not be interested in their IPv6 offerings as long as the large ISPs still are handing IPv4 out.

Part 2: The shifting paradigm of how to firewall with IPv6. With IPv4, just about everyone uses NAT as a poor-mans firewall. They don't have to think about port numbers and the like but they will with IPv6 because dual-stacking is going to be the standard in how it's implemented.

 Instead of having a formal presentation, we will get together and
 discuss anything anyone wants to discuss in brief sessions of no
 more than a few minutes each.  If we have enough people involved
 we can break into smaller groups to handle each topic.

 One very short topic that I will be prepared to discuss for
 a few minutes will be:
      -  Open Source at Two Year Colleges
         Why are text books so damn expensive?

AND YES - We are looking for speakers for upcoming months.
          Volunteers and Recommendations are welcome.

Happy Software Freedom Day!

This month's meeting will be a roundtable discussion about modern web serving.

The CGI.pl/ODBC era gave way to LAMP and we're now onto the next generation:

• node.js and NoSQL make LAMP overkill for many situations

• AJAX/JavaScript are moving much application logic to the browser

• Apache is giving way to lighttpd, node.js, nginx and others

• We've gone from 9" Mac support to 1024 X 768 and now to 4" phones

• URL Shorteners. Who would have thought?

• Users now routinely block ads, scripting and Flash

• Apple has declared war on Flash!

• HTML 5 and CSS 3 are starting to appear in the wild

• Security is finally coming first, not last

How have these factors changed the way you serve web content?

Are the fundamental problems being solved and making your job easier?

Please share your experiences at this roundtable and bring your questions.

                          Arch Linux

                              by

                        Daniel Hedlund
                    <[email protected]>

 Arch Linux is an independently developed, i686- and x86_64-optimised 
 Linux distribution targeted at competent Linux users. It uses 
 'pacman', its home-grown package manager, to provide updates 
 to the latest software applications with full dependency tracking. 
 Operating on a rolling release system, Arch can be installed from 
 a CD image or via an FTP server. The default install provides a 
 solid base that enables users to create a custom installation. 
 In addition, the Arch Build System (ABS) provides a way to easily 
 build new packages, modify the configuration of stock packages, 
 and share these packages with other users via the Arch Linux 
 user repository.

PRESENTATION ONE

Hands-On IPv6 Networking by Ted Mittelstaedt

Ted will wrap-up his multi-month series on IPv6 networking with some demonstrations of real-world DNS client and server configuration and web content serving.

PRESENTATION TWO

Daniel Hedlund will give an introduction to GitHub and demonstrate some command line tools for interacting with GitHub and how you can host a website on GitHub using Octopress (octopress.org)

                              by

                         Scott Garman


 Autoconf. Automake. Libtool. This trio of build configuration 
 utilities (known as the Autotools) are used in a large majority 
 of compiled software applications for Linux, but they remain a 
 mystery to many of us.

 In this gentle introduction to the Autotools, Scott Garman will 
 help lift the veil of uncertainty most people have about them. 
 You'll also learn about the Gnu Coding Standards and the Filesystem 
 Hierarchy Standard, two specifications which explain a lot of the 
 "why" behind the Autotools (yes, there is a method to this madness!). 
 Finally, Scott will offer some practical tips for understanding 
 and fixing errors you may see when building an Autotools-based 
 package. It's sure to be a fun romp for the whole family.

 Since 2005, Randall Munroe's xkcd.com, "A webcomic of romance,
 sarcasm, math, and language" has covered many topics dear to FOSS
 advocates and has been discussed on the PLUG list many times.
 The #1000 comic is expected to appear Friday January 6 just after
 midnight eastern time, making Thursday January 5 "xkcd1k eve".

 Join us for a celebration of XKCD1K eve at the PLUG general
 meeting.  We can display and discuss/explain some of the
 Free/Libre/Open source cartoons, the various weblogs and forums
 that have sprung up around them, draw our own cartoons (Keith
 will bring art paper and pens), perhaps discuss the technology
 of web comics.

 Homework:  bring your own list of favorite xkcd cartoons, and
 we will display them at the meeting.  Bring your artistic and
 "right brained" friends.  Bring your black porkpie hat.  If
 you are Richard Stallman, bring your katana sword.

 Afterwards, at the Lucky Lab Brew Pub at 1945 nw Quimby, we
 can welcome comic #1000, just after 9pm Pacific Time.  Or not,
 Randall is a trickster and may give us strip #1025, avoiding
 the definition the size of a "kilo" ( http://xkcd.com/394/ ) .

             Intro to Salt / Salt Stack (saltstack.org)
                          by Daniel Hedlund 

Salt is a distributed configuration management and remote execution platform built on top of ZeroMQ and Python. Simple, fast, powerful and extensible.

Daniel will give a presentation on the architecture of Salt and how it leverages ZeroMQ to provide a simple but highly scalable and parallel method of software deployment.

"Salt is a distributed remote execution system used to execute commands and query data. It was developed in order to bring the best solutions found in the world of remote execution together and make them better, faster and more malleable. Salt accomplishes this via its ability to handle larger loads of information, and not just dozens, but hundreds or even thousands of individual servers, handle them quickly and through a simple and manageable interface."

Hands-on FreeNAS 64-bit by Michael Dexter

Last month we discussed the history of FreeNAS as a BSD project and the issues related to running FreeNAS on 32-bit repurposed hardware. We toured its user interface and explored its status information from a system administrator's perspective.

This month we will look at this issues relating to building your own 64-bit new hardware system and explore ZFS resource usage.

As before, you are welcome to bring various client machines to interrogate and hopefully pound on FreeNAS with.

Bring your own food and drink.

See you there!

Open Data and Interoperability by Arlo Belshee

Lots of us want to expose our data via RESTful web APIs. We also want to consume data exposed via such APIs. REST + Json works well for this. However, we'd also like to mash up multiple data sources and build higher level tools. For example, it would be nice to create Business Intelligence (BI) tools that can point to any API and start charting the data, or create JavaScript control libraries that can be bound directly to data sources.

Unfortunately, that isn't possible with just REST + Json.

The problem is that each service is custom. No two services follow exactly the same rules. Sure, everything exposes sets of resources. But how do you get from a resource to its related resources? How do you ask the server to tell you about related resources? What, exactly should the server do when it gets a PATCH verb? Each server interprets these differently, which prevents making general tools.

I'm going to talk about the OData protocol. This is an open standard that defines uniform semantics and modeling for RESTful web services. I'll show how this allows general tools to be built, and data from multiple sources to be combined together in interesting ways - without requiring custom code for each server. I'll also show how this enables people working in different languages. A single library can be written for each language which can then support all OData-compliant RESTful web services.

Most of the examples will be with open source frameworks and tools, but I'll also show ways that you can use OData to break out data that is trapped in closed-source systems and expose it to the open source ecosystem.

Agenda:

7:00 - 7:30 Business We will discuss the status of our ongoing projects including PLUG's monthly Advanced Topics meetings, PLUG's monthly hands on clinics etc.

7:30 - 8:30 Presentation and Questions

OpenBSD by Bryan Linton

OpenBSD is a free *nix-like operating system that focuses on security, correctness and developer freedom. With only two remote holes in the default install in over 10 years, OpenBSD has a reputation of being one of the most secure operating systems in common use.

This talk will present a basic overview of what OpenBSD is, and will heavily emphasize what its strengths are. It will also cover the various methods OpenBSD uses to remain secure.

With OpenBSD 5.1 arriving May 1st, we will also discuss some of its new features and improvements.

Many of us will go to the The Lucky Lab Northwest Beer Hall at 1945 NW Quimby after the presentation.

An Introduction to Verilog Synthesis by Galen Seitz

This talk will introduce you to the joys and pitfalls of programmable logic design using Verilog. The focus will be on small designs that could conceivably be undertaken by hobbyists. While we could easily spend weeks on the subject, we will try to cram the following into an hour and a half or so:

• Overview of PALs, CPLDs, and FPGAs
• Why use programmable logic
• Verilog constructs for synthesis
• Synthesis workflow
• Simulation
• Guidelines for synthesis
• A demonstration

If your digital logic skills are a bit rusty, you may want to brush up on your understanding of logic gates and D flip-flops ahead of time. There are many sources of info on the net. Here are couple that may be useful:

Many will break for the Lucky Lab on Hawthorne afterwards.

Lance Albertson of the Oregon State University Open Source Lab will give an introduction to the Ganeti Virtualization Management System.

Ganeti is a robust cluster virtualization management software tool. It’s built on top of existing virtualization technologies such as Xen and KVM and other Open Source software. Its integration with various technologies such as DRBD and LVM results in a cheaper High Availability infrastructure and linear scaling.

This hands-on tutorial will cover a basic overview of Ganeti, the step-by-step install & setup of a single-node and multi-node Ganeti cluster, operating the cluster, and some best practices of Ganeti. Finally, deploying and using a web-based management tool called Ganeti Web Manager.

If you want to participate on the hands-on portion of the talk, feel free to clone his vagrant-ganeti repo on github (https://github.com/ramereth/vagrant-ganeti) prior to the meeting. We'll try and have the box images available on USB drives at the meeting but its always great to have everything setup prior to the meeting and not saturate the wifi.

Lance is the Associate Director of Operations for the Oregon State University Open Source Lab (OSL) and a Gentoo Linux Developer. He joined the Gentoo Linux project in 2003 and have been involved in managing their infrastructure and maintaining about a dozen or so packages in portage. Lance directs all of the hosting and development activities that the OSL provides for the open source community including projects such as Kernel.org, Drupal, Apache Software Foundation, and many many more. Lance has been at the OSL since 2007.

Portland Linux/Unix Group Meeting

It's a little known secret that systemd is extremely capable of starting, controlling and regulating more than just system services, but can easily start an entire Desktop UI. Not many people have sat down and implemented and worked out the problems of starting an X service, a few UI components, the session bus and DBus services for normal users with the mechanisms that systemd provides.

The benefits are obvious: Systemd provides excellent service monitoring and restarting capabilities, provides socket and DBus activation for relevant services, and overall improves desktop startup by allowing user services to start well before core services like Xorg or wayland start. In effect, we're saying goodbye to XDG autostart entirely, and getting back reliability and scalability.

We converted several desktop environments including Tizen's Mobile UI, Xfce4, Enlightenment and more to systemd user sessions. We "pop the hood" and take a look at the implications for startup, what's possible to further improve on the session startup and where we can do better.

Auke Kok is a software engineer at Intel's Open Source Technology Center, and has been attempting to make Linux boot faster since 2007. In 2008, he co-presented the "5-second boot" with Arjan van de Ven at the first LPC. Since then, Auke has worked on further improving the Linux Core OS start sequence, first for Moblin and later with MeeGo, where we made the first switch to systemd. Auke now works on Tizen, which will heavily integrate systemd in the Core OS.

UEFI Secure Boot and Open Source. It's not a 'general war against computation' by Vincent Zimmer, Intel

As 2012 platform firmware embraces UEFI 2.3.1 and ACPI5.0 support, the ability to interoperate with UEFI Secure Boot is imperative. This poses a unique challenge for open software that may not come pre-installed on the platform. With UEFI Secure Boot, though, infrastructure has been put in place to preserve openness, owner choice and control in addition to mitigating concerns of malware targeting the platform. This talk will provide a history of UEFI Secure Boot, an overview of the implementation, deployment practices, and details on the engagement with the open source community.

Vincent Zimmer is a Principal Engineer with Intel Corporation. He has been working on various platform, networking, trusted computing and security technologies around EFI since 1999 and platform firmware since 1992.

The Portland Linux/Unix Group Advanced Topics meeting

Recoupling Computer Science and Computing

A talk and roundtable discussion

There is no question that hybrid telecommunication/computing appliances like those running iOS and Android have put more open source software into the hands of users than any other effort to date but vendors and carriers consistently choose user control over user freedom. While many users and vendors will argue that "people want their systems to 'just work'", intentional and unintentional decoupling of the user computing experiences from the underlying computer science is the norm, despite the fact that developers and systems administrators are equally lazy and "want their systems to 'just work'".

Because no technical barrier exists between these two experiences of a given system, this talk will explore the historic and modern systems that provide the best balance of user and developer experience and open up to a roundtable discussion of other such systems and how to bridge these two experiences and foster computer science in society.

Please be prepared to talk about your experiences, particularly on platforms like Android and web frameworks which can offer full-stack access to sources yet deliver a competitive user experience.

See you there!

Historically, implementation of electronic health records in medical offices have been problematic. Specifically, poor implementation of these products is the leading cause of failure of acceptance of EHRs in these offices. Implementation of EHRs in the small physician office remains poorly documented and this contributes to this failure rate. To address this need, OEMR (The OpenEMR Non-Profit) developed an internship experience with the Department of Medical Informatics and Clinical Epidemiology at Oregon Health and Science University to develop a road map for converting a small physician's office that is still using paper records to OpenEMR, an open source electronic health record, while using open source tools to implement and document the transformation. Documentation was made public on the OEMR wiki (at http://www.oemr.org/wiki/Going_From_Paper_to_Electronic) as a template for future implementations. This presentation is an overview of the documentation completed for the wiki. There are many paths to implementation, but the destination is meaningful use of the OpenEMR system.

Special Thanks: PLUG regular Keith Lofstrom was instrumental to the success of this project, not to mention Dr. Sam Bowen, MD in North Carolina and PLUG speaker Tony McCormick.

Diane Petersen is an emerging clinical informaticist, drawing from her formal education in clinical informatics and her extensive experience as a clinical pharmacist in a variety of settings. Having completed an internship leading and documenting the implementation of OpenEMR, an open source ambulatory electronic health record and practice management software application, Diane is in her last term of the Masters of Biomedical Informatics program at Oregon Health and Science University. She plans to apply her background and knowledge contributing to the improvement of managing healthcare data, and ultimately the improvement of patient care and outcomes.

Mozilla Socorro: an Open Source crash reporting system evolves.

Socorro collects and analyzes three million crash reports a day employing PostgreSQL, HBase, Hadoop, and ElasticSearch glued together with Python. Socorro's data analysis drives the stability and development priorities of Firefox. Five years ago, Socorro was a system that ran on three machines and was tended by just one person. In 2013, it has evolved to become a distributed system running on 120 machines and serving hundreds of terabytes of data. Meanwhile, companies all over the world are adopting Socorro for crash reporting. This talk, an update of one given several years ago, will track the evolution of Socorro and its future in the upcoming world of FirefoxOS.

K Lars Lohn is the Herd Patriarch of the Mozilla WebTools Group. As the author and curator of the Mozilla Socorro Crash Reporting System, Lars has driven its evolution.

Graphite - Scalable Realtime Graphing http://graphite.wikidot.com/

This talk will be my choices as to why I selected collectd / Graphite for performance monitoring my environment at home (email / web / database and test systems). The discussion will include what I looked at, why I discarded the software I did, and show some demonstrations of Graphite, Munin, and if I can get it working again, Ganglia for a comparison of some of their features. I will also discuss some of the hicups I found in configuring some aspects of collectd and Graphite.

Hacking on the new Beagle Bone Black

Description:

Russell recently spent some time working on porting a house-monitoring system from the Beagle Bone (an $89 embedded, ARM-based, I/O rich device running linux http://beagleboard.org/) to the new Beagle Bone Black, a $45 device which is faster, includes video and 2G of onboard flash. The sensors required a one-wire bus, one of which the original Beagle Bone had configured out of the box. The Beagle Bone Black had none. This talk is a description of what it took to get one-wire (specifically w1-gpio) going with his own custom "cape" (a daughter-board for the Beagle Bone).

Biography:

Russell Senior has been a GNU/Linux user for over 20 years, since the 0.99plN days, using it both recreationally and professionally as a research programmer/scientific data analyst. Since 2005, Russell has become involved as a principal volunteer with the Personal Telco Project (https://personaltelco.net), during which he has worked on embedded systems, primarily network routers. He contributes to the development and improvement of the OpenWrt project. In the last couple years, he has worked on monitoring systems involving Arduino and, since last year, the Beagle Bone and has learned a bit about the Angstrom distribution of linux for embedded devices.

Virtual Private Networking

Our illustrious IPv6 authority, Ted Mittelstaedt, will give a talk on popular Virtual Private Network options, including:

1) standard IPSec clients - require static IP at each endpoint, and are supported out of the box by Windows, Cisco IOS, Mac, and Unix using raccoon and similar programs.

2) Modified IPSec VPN clients - example is the Cisco IPSec VPN client. This is a proprietary modification used to allow one end to have a dynamic IP number.

3) SSL VPN clients. Cisco has one they call AnyConnect that is proprietary. OpenVPN is another example.

4) PPTP. This was supposed to have died years ago but since Microsoft ships the PPTP client with Windows it is still very useful in situations where the network admin is forced to provide VPN services to clients that she has no control over.

5) L2TP. This is what PPTP morphed into, Microsoft supports it natively, so it has the same benefits (to the network admin) as PPTP plus the Microsoft implementation allows for encryption using IPSec with certificates.

Brian Martin will talk about his early experiences with Samba 4

Samba provides open-source support for the Microsoft file sharing protocol. Version 4 of Samba was released late last year. It represented years of work and a major, some would say massive upgrade to Samba to include the ability to be a fully functional Active Directory server. Given the large scale changes, many people have been avoiding production Samba 4 use while waiting for the bugs to be worked out. Brian Martin has now started migrating production environments to Samba 4 and will discuss his early experiences.

Why: The pursuit of technology freedom

The Android permission model opens up a number of opportunities for apps to bypass the established single-app permission checks that Android users rely on to control data flow and application behavior on their devices. I'll do my best to terrify the Android-using audience by describing the attack surface for colluding applications and showing interactive visualizations of multi-app data flow. We'll look at the Android permission model, the user-interface it results in, and I'll show just how easy it is to make apps that look innocuous.

Portland Linux/Unix Group Advanced Topics Meeting Announcement

Who: Brian Rohan and Michael Dexter

What: Speaking in Public is Easy

Where: Free Geek, 1731 SE 10th Avenue, Portland (Left Entrance)

When: Tuesday, January 21st, 2014 at 7pm

Why: The pursuit of technology freedom

You read that right: Speaking in public is easy and there is nothing stopping you from giving the next informative and compelling PLUG talk.

• You are guaranteed to have a unique topic, experience and perspective
• Audiences are far kinder than you expect (only pros get boo'd!)
• Visuals are always optional
• No one was born a public speaker
• There are great resources out there to help you
• Most things that go wrong have nothing to do with you (Tsunamis!)
• Live demos are... risky, but cool
• The OSCON and LFNW CFP's close shortly (hint hint)

Brian and Michael will give you a pragmatic tour of exactly what is involved in open source conference speaking and explain precisely how nothing is stopping you from getting involved thanks to local organizations like the Portland Linux/Unix Group.

Brian says:

In 2007 I made the switch from being a machinist to a real estate agent, shortly thereafter I was invited to investigate a Toastmasters club, in order to become a better communicator. Through 5 years and over 40 speeches in Toastmasters I reached the highest level of Distinguished Toastmaster. Simply stepping out of my comfort zone has given me the opportunity introduce dignitaries, and MC fund-raising events for worthwhile causes (notably a record breaking Clark County Republican Party Lincoln Day Dinner auction). Currently I am a recognized top 2% leader in AdvoCare International, helping others achieve their physical and financial goals.

I enjoy using Linux on a personal level for the freedom that it represents.

"You never get rid of public speaking butterflies, you just get them to fly in formation: ~Marv Serhan

Michael says:

Never in a 1,000 years will I speak in public yet I find myself doing it several times a month in Portland and at conferences around the world. I guarantee I'm no Brian Rohan but I fill rooms and get applause. The secret is finding the right room and just doing it. I will talk about the absolute worst that can happen (rarely what you think it would be), the open source conference community and how to get from submitting a proposal to stepping down from the stage.

The Portland Linux/Unix Group: Portland's monthly, three-track tech conference, celebrating its 20th anniversary this spring!

• Who: Brian Rohan and Michael Dexter
• What: Public Speaking is the Greatest Skill You Can Possess
• Where: PSU, 1930 SW 4th Ave. Room FAB 86-01 (Lower Level)

• Why: The pursuit of technology freedom
• Stream: http://pdxlinux.org/live/

Brian and Michael are back to teach you everything you ever wanted to know about speaking at an open source from PLUG (hint hint) to OSCON.

Brian has years as an experienced Distinguished Toastmaster (beer available at the Lucky Lab NW after the meeting) and Michael has just submitted his paper for the upcoming AsiaBSDCon conference on a topic he had previously known nothing about.

Why should you give a talk?

• You are guaranteed to have a unique topic, experience and perspective
• Audiences are far kinder than you expect (only pros get boo'd!)
• Visuals are always optional and are flexible in format
• No one was born a public speaker, it's simply a learned skill
• There are great resources out there to help you
• Most things that go wrong have nothing to do with you (Tsunamis!)
• Live demos are... risky, but useful
• The LFNW and other CFP's close shortly (hint hint)

Highlight from our Advanced Topics talk: (paraphrased) "My mom got more value out of learning to community with Toastmasters than two years of a (VERY impressive school) scholarship."

YOU may change careers a dozen times in your life and need a new skill set for each job but will ALWAYS need to express yourself and communicate on behalf of yourself and your team. Let PLUG be that first step in what could be worth more than a (VERY impressive school) scholarship!

Daniel Hedlund will be giving an intermediate to advanced level talk on DTrace and SystemTap.

DTrace (http://dtrace.org/blogs/about/) is a dynamic tracing framework, originally developed for Solaris, has been released under the CDDL license and ported to many other Unix-like OSes including FreeBSD, OS X and Linux. SystemTap (https://sourceware.org/systemtap/) provides similar functionality to DTrace but is Linux specific and released under the GPL.

Dynamic tracing tools make it possible to safely inject instrumentation points (probes) into running applications on production environments; no recompilation is necessary and there is only minimal performance overhead when being used, and no overhead when not. Probes can be used to gather performance metrics to identify bottlenecks, create aggregate statistics such as the size distribution of filesystem writes, or to introspect arguments passed to individual functions in a running application without ever taking it offline.

UNIX introduced the notion of software tools, small programs assembled together as pipelines. Almost as innovative what its notion of a workbench, a place where work in progress could be shared by passing references, file paths, among collaborators.

I draw huge inspiration from these contributions, both of which happened within my professional lifetime. In this talk I will describe analogous structures in Federated Wiki, a project that hopes to host the doing of things as well as the talk about doing things.

Ward Cunningham has worked for and consulted to daring startups and huge corporations. He has served as CTO, Director, Fellow, Principle Engineer and Inventor. He is best known for creating wiki. He leads an open-source project rebuilding wiki to solve more complex sharing situations addressing some of societies toughest problems.

We will look at the security provided by OpenSSH and how the environment it is used in affects it's security. When can SSH security improve network security and when can't it.

This presentation assumes you have a basic understanding of SSH and how it is setup. Those topics will be reviewed very rapidly as we dig deeper into the security aspects of SSH. The discussion concentrates on SSH authentication using asymetric or public key encryption.

SSH is widely used to provide convenient and secure access to multiple machines on a local network, and to tunnel into remote networks to access machines on those networks that aren't directly visible to your local machine. We will analyze various use scenario's of SSH in these two usage scenario's and also the advantages and disadvantages of using an agent to facilitate SSH connections. For each of these scenario's, we will discuss the privacy aspects of one's passphrase and private keys, how secure the transmitted data is, and the ability of others to 'borrow' your credentials.

You should walk away from this presentation with a better understanding of what actions you need to take to maximize your privacy, while reaping the benefits of using SSH.

There are countless available text editors, programming languages and Integrated Development Environments (IDEs) but few are guaranteed to be present on any given system. On POSIX Unix systems, the vi(1) text editor and sh(1) shell are required by the POSIX (opengroup.org) standard and might be the only development tools at your disposal. While some developers may consider these tools equivalent to a doughnut spare tire that should not be used over 50MPH, others embrace them and have used them for decades. Some would also argue that you should learn the rules before you break them in order to appreciate higher-level languages.

This talk will be a crash course in vi(1) and sh(1) with examples from a 2500 line virtualization management project that uses a number of scripting techniques.

A look at the technical and legal issues surrounding home construction of firearms, focusing on semi-automatic AK-47 style rifles.

Home gun building brings interesting legal and technical challenges needed to keep someone both safe and on the right side of the law. This requires an individual to be both an amateur metalsmith as well as knowing the ins and outs of firearms and international patent law. This talk will discuss the building of the semi-automatic AK47 rifle from a technical perspective, from demilling parts kits to the construction of a fully functional semi-automatic weapon.

We will also discuss the origins of the AK design, the history of it’s variants and its current patent status as a public domain firearm design, delving into Soviet and Russian Federation patent law as well as US firearms law.

The Linux Clinic meets once a month on the third Sunday from 1 - 5 pm at Free Geek, 1731 SE 10th Avenue, Portland, 97214.

Bring your Linux computer that is being a brat and we'll teach it some manners. Or bring your computer that has some evil operating system on it and we'll send it home with a shiny, clean Linux distro. Or just come and look over shoulders to see what Linux is all about.

If you already know Linux well, the Clinic is also a good place to learn how to help users troubleshoot problems. It's excellent training for tech support work in Linux.

We have monitors, mice, keyboards, and miscellanous other perifpherals, so generally all you need to bring is the box.

There will also be coffee and people usually bring munchies as well. After all, you can't do computers on an empty tummy.

Software-Defined Radio Hack Session

Want to get into software-defined radio hacking but don't know where to start? Bring your laptop and an RTL-SDR dongle, HackRF, BladeRF, USRP, or other SDR hardware to this hack session and get expert help.

Jared Boone and Kenny McElroy will be on hand to help install and configure software and explain concepts. Do try to install GNU Radio on your computer before you come, since it can be a long, slow process. If you get into trouble, we will do their best to get you unstuck. For those who come with GNU Radio already functional, we will advise you on things to experiment with. If you do not already own a software-defined radio, purchasing an RTL-SDR dongle from HackerWarehouse.com or NooElec.com is recommended. They are quite inexpensive ($15 to $20) but very functional and a great way to get started in software-defined radio.

Bring some radio-based toys to hack on! If you can't make this meeting, be sure to watch Calagator, where Jared and Kenny will be starting an SDR meetup in the next few weeks.

Jared Boone has an ongoing obsession with software-defined radio. He helped with the design and coding of the HackRF SDR and has done some privacy-related work, particularly around automotive tire pressure monitors. He is a frequent user of GNU Radio, baudline, and radio signal processing techniques.

Kenny McElroy is a computer security researcher, focused on improving understanding and visualization of how the ones and zeros of computer security move around in the real world.

Organizer's Notes: Ham Radio Outlet in Tigard has a number of good magazines including the July/August QEX which features an article on GNU Radio. You may also want to read:

Web-based file hosting, synchronization, and collaborative editing services have made sharing files easier than ever. While these features aren't new, the web 2.0 cloud context they are being offered through has brought them to the reach of the average user with low barriers to use. These freemium services often come at a hidden price of control, privacy, and usually security. This presentation will give an overview of what ownCloud is, why one might use it, what technologies it employs, the services & features it offers, how to set it up, and discuss the use case the presenter has deployed.

Jesse Bufton is an independent web designer/developer and sometimes graphic designer. Jesse began his journey to *nix operating systems in 2000.

CFPs or Calls for Papers/Participation are something you generally are oblivious to or schedule your whole year around. A CFP is what conference organizers use to formally announce their desire for speakers at an upcoming event. They often set guidelines and requirements for the talk and the organizers of successful conferences can find themselves rejecting hundreds of proposals. Michael will analyze a number of prominent open source community CFPs and will step through every stage of a CFP that requires an extended abstract, paper and presentation. Attendees will hear repeatedly how astonishingly easy some CFPs (like PLUG's) are to respond to and in will fact have their proposals ready by the end of the talk.

Using common household tools such as Postfix, Dovecot, and MySQL, you can have a pointy clicky UI for your mail administration and webmail needs.

I’ll be showing a demo that utilizes Postfix, Dovecot, PostfixAdmin, Sieve, MySQL, and RoundCube. Account manipulation (creating domains and users) through a webby, webmail, and server side mail filters.

Copyleft licenses, particularly the GPL and LGPL, are widely used throughout the Free Software community. However, recent for-profit corporate interest in Free Software development has led to a renewed preference toward non-copyleft licensing by for-profit entities. Meanwhile, many for-profit entities that do use copyleft for their own software now do so in a manner that most copyleft aficionados find, at best, distasteful and at worst, abusive.

A long-standing truce exists in our community between fans of non-copyleft licensing and copyleft. No one in the copyleft communities disputes that non-copylefted Free Software is an important part of our community. However, copyleft faces new challenges that make past debates about the appropriateness of copyleft seem quite minor by comparison.

This talk will discuss all aspects of the complicated situation facing copyleft, including younger developers apparent preference for non-copyleft licensing (as expressed, in part, in the "post-open source" debates), the widespread and common failures for companies to comply with GPL's relatively easy requirements, and how licensing choices are today, unlike in the past, rarely in the hands of individual developers, but instead their corporate employers.

Bradley M. Kuhn is the President and Distinguished Technologist at Software Freedom Conservancy (sfconservancy.org) and on the Board of Directors of the Free Software Foundation (FSF). Kuhn began his work in the software freedom movement as a volunteer in 1992, when he became an early adopter of the GNU/Linux operating system, and began contributing to various FLOSS projects. He worked during the 1990s as a system administrator and software developer for various companies, and taught AP Computer Science at Walnut Hills High School in Cincinnati. Kuhn's non-profit career began in 2000, when he was hired by the FSF. As FSF's Executive Director from 2001–2005, Kuhn led FSF's GPL enforcement, launched its Associate Member program, and invented the Affero GPL. From 2005-2010, Kuhn worked as the Policy Analyst and Technology Director of the Software Freedom Law Center. Kuhn was the primary volunteer for Conservancy from 2006–2010, and has been a full-time staffer since early 2011. Kuhn holds a summa cum laude B.S. in Computer Science from Loyola University in Maryland, and an M.S. in Computer Science from the University of Cincinnati. Kuhn's Master's thesis discussed methods for dynamic interoperability of FLOSS programming languages. Kuhn received the O'Reilly Open Source Award in 2012, in recognition for his lifelong policy work on copyleft licensing.

FreeBSD invented the modern Unix container with jail(8) in the year 2000 and today operates as an EC2 and Hyper-V guest, Xen Dom0 and DomU and now includes bhyve, the native FreeBSD Hypervisor. Michael wrote his first jail(8) management system in 2005 and has since operated NetBSD/Xen in production and was the first community user of bhyve, the FreeBSD hypervisor introduced with FreeBSD 10.0. bhyve is a modern, emulation-free hypervisor that relies on the Extended Page Table feature found in modern Intel and AMD CPUs. bhyve provides bare-metal performance for Unix virtual machines and an in some cases will in fact provide better than bare-metal performance.

FreeBSD Xen Dom0 support has been many years in the making but is beginning to see the light of day. Michael is working with Xen developer Roger Pau Monné and aims to have a real-world report on the status of this unique effort.

Combined, these technologies are establishing FreeBSD as an emerging first class virtualization platform with an increasing adoption by "cloud" service providers.

Portland Linux/Unix Group: Block Storage Device Life Cycles

Block storage has joined electricity as one of the fundamental technologies on which we are completely and irrevocably dependent. The two technologies are in fact becoming inextricable now that computers control virtually every electrical system from the distribution grids on up, and computers themselves are completely dependent on electricity to operate. Both technologies have undergone countless innovations yet still operate largely on their original basic principles. While high in capacity, fast and affordable, the modern hardware block storage device or “hard disk” operates on the same principles as the original 1956 IBM 350 disk storage unit and most solid-state alternatives emulate hard disks. Beginning with the Berkeley Fast File System, the BSD family of operating systems has played a key role in the evolution of general purpose block storage and continues this innovation with technologies like virtual block storage devices, GEOM, UFS2, ZFS, GELI, HAST, GEOM Journaling, FUSE, tmpfs and the NAND Flash framework. This paper will survey the available block device options in the FreeBSD operating system and explore their practical uses in modern storage architectures.

FreeBSD is unique in that it provides the reference platform for the Unix File System and is now a tier one Zettabyte File System or ZFS platform. The 10.0 release of FreeBSD is particularly unique in that it includes in-kernel iSCSI network block device sharing, the NAND Flash framework, a FUSE implementation and the bhyve hypervisor which can leverage and help test most FreeBSD storage technologies. The FreeBSD ports collection also includes support for guest file systems such as ext2 and NTFS, which provide new opportunities to "round trip" virtual and physical machines using bhyve and tools such as the iBFT iSCSI boot framework.

Finally, while an unprecedented block storage toolkit can enable extensive experimentation, there are pragmatic issues surrounding production storage architectures. This paper will touch on real world block storage solutions built with FreeBSD and its derivatives. These derivatives include the FreeNAS storage appliance, which provides networked block and file storage to a myriad of Unix and non-Unix clients. Pragmatic issues surrounding verifiable data integrity include: understanding and embracing ZFS behavior and limits, observing disk and partition health in addition to data integrity, understanding the implications of file naming, maintaining backups and restoring desired data in a timely manner.

With over seven million downloads and hundreds of thousands of users (if not more) around the world, FreeNAS is easily the world's most popular software-defined Network Attached Storage (NAS) software.

FreeNAS is based on FreeBSD and the ZFS enterprise grade open source file system. The FreeNAS graphical user interface has evolved from being PHP-based, followed by Django/JavaScript based and is now moving to an all-JavaScript, asynchronous and Websockets-based framework that allows for both graphical and command line interfaces.

This hands-on demonstration will explain how the new Cisco/Vyatta-like FreeNAS CLI works for basic storage server configuration. It will also show the built-in interface debugging tools which show what is going on under the hood.

Michael provides FreeNAS support with Gainframe and does way, way too much in the BSD community.

We are addicted to storage devices like hard and solid state disks.

Modern computing begins with storage and could survive quite some time without the computing part, as demonstrated by past storage devices like the Rosetta Stone for which we struggle to decode.

This means HDD's and SSD's are reliable, right?

Alas, they are not. In fact the situation is somewhat terrifying. File systems have made significant progress in the last decade but remarkably, there are still significant issues surrounding the devices they inhabit.

Storage devices are inconsistent, to put it politely, about notifying the user of existing, potential and impending problems. Built-in, standard-ish reporting mechanisms like S.M.A.R.T. exist but pose as many challenges as they address. Some storage "health" monitoring data is straight-forward, some is not:

What: Linux as a security camera monitoring platform

When: Tuesday, 16 February 2016, at 7PM
Why: Because combining physical and digital security is an interesting puzzle
Stream: http://pdxlinux.org/live

Setting up a camera in Linux is relatively easy. With any luck, you plug in the USB cable and it "just works". But what if you need ten cameras? What if you need to store increasingly large amounts of footage for liability purposes? What if you need to be able to access the realtime feed from any (or all) of those cameras from anywhere in the world? What if you need fine-grained motion detection for some of the cameras, scheduled recording capabilities for others at certain times of day, and provide varying levels of access to multiple users?

This problem set is normally solved in a business environment by purchasing expensive (and frequently proprietary) security camera systems at a significant cost. However, it's possible to accomplish all of these things with a Linux-based application called ZoneMinder. During this talk, you'll be walked through the process of setting up a fully featured security camera and monitoring system, and will have the opportunity to learn about and/or discuss some of the supportive tech such as an Apache proxy, firewall and router configuration, and pruning and backing up video archives.

PostgreSQL 9.5 has many new and cool features for database users, making the venerable RDBMS suitable for even more workloads. Among them are:

• UPSERT for high-concurrency insert/update operations
• Row Level Security, integrated with SELinux, for ultimate data security
• CUBE and ROLLUP for sophisticated analytics
• FDW partitioning for data federation
• BRIN indexes for big data
• More JSON goodness

PostgreSQL Core Team member Josh Berkus will take you on a tour of the new features, including demos of many of them, and field questions about PostgreSQL in general.

What's in a mirror?

If you've spent any time GNU/Linux distro hopping or testing virtualization strategies, you have probably spent a non-trivial amount of time in the "nearest" download mirror. Such mirrors vary in speed, quality and navigability. The burden for upholding quality in each of these respects falls both on the often-volunteer mirror maintainers and the often-volunteer project maintainers. Failure from a mirror's perspective is obvious: You can't access the materials you want to download or what you download is corrupt. In the case of the downloads themselves, THIS:

mirror.org/releases/amd64/20160704/livedvd-amd64-multilib-20160704.iso

I was cleaning up my local mirror and came across this path and installer ISO and... HAVE NO IDEA WHAT OS IT IS.

This roundtable will discuss the good, the bad and the ugly of such mirroring and what to do about it, ideally resulting in a draft proposal for a conventions that projects and mirrors could follow.

How to get a Municipal Broadband network in the City of Portland

As many of you know, Russell has been kind of passionate about building an open-access Internet infrastructure in Portland for the last decade or more. No privately owned network would voluntarily allow open-access, and hasn't since the DSL days (when they were required to), and the Feds, namely the FCC has been steadfast in its refusal to enforce line-sharing (essentially the same thing as open access) on infrastructure built since 1996. Many of you may have heard about the FCC action in December rescinding the relatively new Title II regulation of ISPs and the Network Neutrality rules that went with it. With the consciousness raising this event has provided, there is a new window of opportunity from the groundswell of interest to create pressure on our political systems, namely City Council in Portland OR, failing that, an initiative petition to provide a local solution.

Russell will describe the problem and what a solution would look like, where the user ends up in the driver seat.

To fight global warming on the local level requires a change in thinking. We need to consider how new systems can be easily deployed and used by local groups. Supported by regional groups of academics, scientists, citizen scientists, journalists, environmental hackers, communities from the DIY and Maker movements. Systems that can aid local populations in their understanding of environmental and climate changes and help them deal with those changes. Our systems are aimed at the area that is the difference between today's weather and long-term climate changes ahead. These systems are designed to be the “last mile” of climate change monitoring, allowing local communities around the world to monitor their climate and take steps to mitigate changes. The systems will be owned and run by these communities with limited outside technical support, and can either stand alone or be tied together into an ad-hoc network similar to a small network of cellphone towers. Using our system to ask three questions: What is happening to our climate and environment? What does it mean? And what can we do about it? The hard data collected from the system, leaders in communities can begin planning how they will adapt and stay in place in their decision-making process. The GMIBS-Project will design, develop, and produce low-cost systems to aid local groups efforts to monitor and mitigate climate change. By this we hope to foster an ecosystem of users, developers, contributors, and competitors in an open global marketplace for climate change intelligent aid tool systems.

About Robin

Windows has a hard-earned reputation for appalling security and reliability but, better late than never, has matured into a relatively stable and secure desktop and server problem. Windows can run many popular open source desktop applications and has an incredibly-long history of on-again and off-again supporting Unix/POSIX environments such as Interix/SFU and Cygwin, and now ships with Linux emulation. These tools vary wildly in their depth of frustration to Unix users but do provide a gateway to some extremely-interesting yet intentionally-vague open source opportunities that will be demonstrated.

Rapid web application development with Angular: Catch a glimpse of what a full stack web application looks like that is built with open source resources like Angular, NgRx, GraphQL, and AWS Amplify. A lot has changed since the version of Javascript changed in 2015. Open source client side frameworks have dramatically changed to provide opportunities to build large client side applications that are performant while also cloud infrastructure has made scaling javascript possible with the availability of powerful tools without investing in expensive servers.

About the Speaker

This presentation will walk through the use of a Yubikey 4 to hold an RSA PGP private key. Public key encryption requires protection of the private key. If control of the private key is lost, all reasoning about signatures and encryption is compromised. Storing private keys on a hard disk and processed by the PC makes the private key vulnerable to compromise. A Yubikey promises to key your private key secret. There will also be a digression during the presentation into so-called true Random Number Generators, e.g. ChaosKey and InfiniteNoise.

There is no magic bullet for quality. Nor is there a right tool, script, or any amount of automation that can replace actual thought and effort. Building quality in requires that you first understand what it is. This talk will focus first on defining quality, then we will move to strategies for building the goodness in, and finally ways to test to ensure that both you and your "customers" are getting what they want.

About Heather

Why do packets die? What happens inside data center switches and WAN routers that cause packets to die? In this talk, Tony does packet walks explaining in simple, relatable terms what happens when a packet leaves a server and doesn't make it's destination. Network congestion and its affects on buffering, queuing, QoS, rate limiting and shaping are all topics covered. Topics that can be scary to server administrators, but Tony breaks them down to very simple components. Also discussions on why protocol overhead doesn't much matter, and why jumbo frames don't matter to the network for performance are discussed.

Tony Bourke is a networking instructor teaching primarily Cisco and related technologies. He is also a certified skydiving instructor and parachute rigger. He lives in Portland, Oregon but can be found all over the world teaching or skydiving (or both).

As far as I know, no request to open source something has ever been denied by my employer, and while the company has always had the same "go for it" attitude, the folks writing code are only just starting to gain momentum releasing things publicly. I'll talk about showing other folks in the company the benefits of sharing code internally, how that exposed the benefits of open-source in general, and how we as a company progressed to getting DBIx::Class::Events onto the CPAN.

The Free Software/Open Source community appears to be at a crossroads.

A brave woman declared that "enough is enough" with the disturbing statements of a pivotal figure in the community and it rightfully cost that figure a number of prominent positions. Remarkably, she wasn't the first woman to challenge a foundation leader this year and help usher them to the door.

Responses to such confrontations have ranged from false narratives to the proposal of morality-enforcing licenses for software.

One theme however, is the chilling effect that disturbing, and at times unlawful behavior in the community causes, and the efforts to content with it. Why participate in communities with these issues? This passive discouragement is often combined with direct discouragement and countless forms of divisiveness.

Yet we press on, and work to resolve these bugs, one by one.

This meeting will be an open forum to share your experiences with discouragement in the free software/open source community. Trolls need not attend but will be educated by a panel of experts if they do.

Glass Beatstation: An open source mobile and modular musical interface for Linux machines and musicians that don’t know how to use Linux

As a self-taught/amateur programmer, I was able to use open source programs to start building the versatile music workstation I’ve long dreamed of. The fact that I have been able to get this project functional to any degree is a great credit to the FLO (Free/Libre/Open Source) community. In the process I’ve learned about many of the benefits and learning curves of FLO hardware and software. I primarily used Python, Open-Stage-Control, Sooperlooper, Ardour, Puredata and the Kxstudio repositories, and have iterated an extra portable version of the project on raspberry pi. I will share the perspectives I have gained in the process how I was able to receive AND share knowledge with Linux users both new and experienced alike. Because of this, I’ve learned much about bridging the gap between those people already familiar with Linux/FLO technology, and those who aren’t familiar – yet.

Athan Spathas teaches robotics to kids and supports open source software however he can: one is as likely to find him performing on his linux based portable studio as much as find him performing on it, doing demos, or educating others about the benefits of open source technology.

A look at the journey from ASCII to UTF-8. I'll discuss the ramifications of the results of this journey for users and highlight cautions for developers. We have gone from the simple, a character is a byte, to a character may be tens of bytes, and worse monospace characters are not always the same width when displayed. This is a overview of features every GNU/Linux user should be aware of. It also highlights some issues programmers and sysadmins will face.

Russell has been measuring an array of temperature sensors in and around his house since October-ish 2011, primarily Dallas Semiconductor DS18B20 one-wire sensors (previously talk: 2013-06-06 Hacking on the Beagle Bone Black). For years, he's had a few Oregon Scientific wireless temperature sensors outside, but no way to log the temperatures for posterity. About a year ago, in early December 2018, he discovered a project called rtl_433 that uses a software defined radio to receive and decode the signals coming from these and similar sensors. so that they can be logged. This talk will describe a few of the things that are possible with rtl_433 and what Russell does and doesn't do with the data.

About Russell:

Russell has been a Linux user since 1992. He worked for a few decades doing data management, programming, and analysis for a small scientific consulting firm. Since 2005 he has been deeply involved in the Personal Telco Project and trying to bring about telecommunications in the users interests, while also hacking on router firmware. For two years, he's been involved in an active effort to bring publicly-owned fiber infrastructure to the Portland metro area (in furtherance of the Personal Telco goal). He has a possibly unnatural love for serial consoles and RS-232, but is too smitten to be ashamed. He describes himself as self-under-employed. Will work on Linux'y things for money. Will work on Science'y/measurement'y things for money, as long as Linux is or can be involved somehow. He's very interested in trying to solve your telemetry problems with off-the-shelf wifi equipment and some elbow grease, if you've got some.

Why: The pursuit of technology freedom

When developing software for multiple platforms, designing a functional user interface can often be a challenge.

Often C/C++, C# or even Python is used, but an overlooked, full-fledged IDE and development tool is Lazarus / Free Pascal.

Using Object Pascal, a strongly typed, easy to read, learn and modern compiled programming language, you can quickly write advanced applications and design beautiful user interfaces with the strong component based model and form designer.

It has its inspiration from Delphi, a commercial development tool which also can target multiple platforms, though the IDE itself runs on Windows only.

The underlying Free Pascal compiler has a high degree of compatibility, which means you can share code between Delphi and Free Pascal fairly easy.

In this presentation I will touch on the versatility and benefits of using this development tool for your next open source project and how easy it is to get started.

Why: The pursuit of technology freedom

his talk presents FineIBT, a compiler-based enhancement that enables fine-grained forward-edge Control-Flow Integrity (CFI) policies on top of Intel's Control-flow Enforcement Technology (CET). By combining the new hardware features with compiler instrumentation, FineIBT anchors indirect control transfers to sanity checks, enabling policies more restrictive than those supported solely by CET and increasing its effectiveness against control-flow hijacking attacks. An evaluation through custom benchmarks shown that FineIBT provides similar security guarantees with less performance costs when compared to Clang CFI, retaining its penalty between 1% and 7% while the latter added overheads between 5% and 53%. Beyond that, FineIBT also has other perks, such as benefiting from the CET's hardening against transient execution attacks and not depending on Link-Time Optimizations. This talk will explore the FineIBT implementation recently sent to the kernel-hardening mailing list, then discuss specific scenarios, such as how it could be used in the Linux kernel, possible improvements and expected challenges.

Russell volunteers with the Portland State Aerospace Society's (PSAS) OreSat program as an Industry Advisor. PSAS is a rocket club at Portland State University. The OreSat program works towards having small interactive satellites put into orbit by friendly launch services. OreSat currently consists of three small satellites based on a common design, the first one is due to launch in January. Russell's role is to help out with a system called dxwifi, a long distance S-band communication link. The goal is for ground-based student groups around the state to receive live video broadcast from orbit as the satellite passes overhead. Earlier this year, a high school student applied and got our satellite a ride on a high altitude balloon through a NASA program. One of the goals was to capture wifi data being transmitted by the payload. Because of the distances involved, this requires aiming a directional antenna at the balloon. This talk will tell the story of how Russell waded his way towards a solution using math, some hand tools, open-source software and some ingenuity.

I will also look at the current RISC-V SoC's that are capable of running Linux and available dev boards. I will also talk about how support in Linux for RISC-V is continuing to evolve such as the introduction of KVM RISC-V support and look at RISC-V hardware support that is in the process of being upstreamed. I will describe how the RISC-V Platform Specification Task Group is trying to standardize boot and runtime requirements with the creation of the Linux-2022 specification.

Sound is a major part of the Linux desktop and now there's a new project to make your audio experience even better! Or maybe not. This talk will explore the features and changes involved in switching a system from Pulseaudio to Pipwire for audio device management.

The new Pipewire daemon promises to improve the state of audio playback on Linux but with this change comes questions regarding the impact to different users and use cases. In this talk I'll go over the impact Pipewire can have for various different users and provide a basic configuration for those brave enough to give it a try. I will also outline some of the history surrounding the audio stack in Linux with a focus on how Pipewire plans to implement new features while maintaining compatibility with older applications.

About Ben I am a QA Test Technician with a background in tech support for Mac/Windows/Linux desktop users. When not talking to customers I can be found customizing Linux distros and building systems that solve problems before they occur.

What: The Transit Appliance Project
Where: Zoom, flawed as it is, link below
When: Thursday, January 6th, 2022 at 7pm
Why: The pursuit of technology freedom

This talk will explore the history and future of the Transit Appliance project, an open source project which makes use of TriMet and other public web services to display transit arrivals on fixed location screens in apartment and office lobbies, cafes, schools and other community locations. The project is hosted by the non-profit Portland Transport and currently operates more than 60 screens around the region. The project relies on Raspberry Pi processors and a variety of cloud services to provide a minimal cost solution to the display of transit and micromobility information.

About Chris Chris Smith is the lead developer of the non-profit, open source Transit Appliance project. For two decades his day job was leading web architecture for Xerox. He serves on the board of Portland Streetcar Inc. and also served for twelve years on the Portland Planning and Sustainability Commission. His passion is the intersection of technology and sustainable urban policy.

Returning to Zoom for now

PLUG aims to dogfood free and open source technologies whenever possible and Jit.si had a good run. It is quirky and very difficult to manage as a moderator, but it is free software. Recording meetings proved unworkable but thank you Vincent for spinning up a Jit.si VM during a meeting and removing the watermark. Many colleagues have reported that web-based Zoom is working better than ever with free and open source desktop operating systems and for the success of PLUG and my sanity as a moderator, I need to use the best tool for the job. Please continue to send your ideas for better tools and I would not rule out moving to a solution that someone is willing to take ownership of, as Vincent did with the Jit.si VM.

What: This is a test(1): A shell scripter's guide to ubiquitous assumption testing
Where: Zoom, flawed as it is, link below
When: Thursday, February 3rd, 2022 at 7pm
Why: The pursuit of technology freedom

"Look before you leap" is a valuable lesson in many aspects of life but particularly in computer science and administration. Responsible developers make extensive use of the test(1), a.k.a. "[" utility which quickly and programmatically tests assumptions as simple as, "does this file exist", relying on zero and non-zero return values to answer that question. This deceptively-simple yet highly-efficient use of return values can avoid hours of debugging and achieve goals such as idempotence. This talk will explain the importance of the test(1) utility, and explain similar functionality in other utilities such as FreeBSD's grep(1), kldstat(8), and others that support "-q quiet" mode. It will also identify opportunities for additional "quiet mode" functionality.

Who: Ted Mittelstaedt
What: Setting up inexpensive home security cameras with ZoneMinder to secure your home or business
Where: 5500 SW Dosch Rd, Portland
When: Thursday, February 2nd, 2023 at 7pm
Why: The pursuit of technology freedom

Today there are a number of inexpensive home security cameras on the market that can be used to decrease the chance that your home or property will be tampered with. There's been a rash of catalytic converter and gasoline thefts in the Portland area in recent years, these require expensive replacements and repair of vehicle gas tanks that have been drilled into. Many homes in Portland do not have garages and residents use street parking. With the increasing use of electric vehicles and portable charging cables, the potential for theft and mischief exists as well. While a camera system may not prevent a theft, a good system can get a clear picture of the perpetrators and allow police to make an arrest. These systems also serve as a visual deterrent. This presentation will cover several camera systems and different concerns for mounting, cabling, and camera selection as well as recording camera data using ZoneMinder running on Linux and considerations for setting up this system.

Who: Julia Iacoviello
What: Using DRBD and LINSTOR to Facilitate Cloud Migration and Mobility
Where: 5500 SW Dosch Rd, Portland
When: Thursday, August 3rd, 2023 at 7pm
Why: The pursuit of technology freedom

There are many advantages to flexible cloud storage, but even with a good idea of how you might implement your environment in the cloud, the challenge of transferring legacy data may stand in your way. In this talk, Julia Iacoviello from LINBIT will explain core concepts of the open source, distributed replicated storage system, DRBD, as well as the open source storage management software, LINSTOR. Then, we will explore how these technologies can be leveraged to mitigate pain points in migrating production databases and other services into the cloud, including to containerized applications that rely on persistent stateful storage. Special considerations to be made for migration of existing data will be highlighted in this talk; additionally, a broad base of information about DRBD and general high-availability storage will be provided, with the hope that all that attend may learn something applicable to their particular use case, now or in the future.
