Come join us on Friday, Feb 27, at Paddy's Bar and Grill (SW 1st/Yamhill) from 6-8 pm for Puppet PDX, an opportunity to get together and talk about all things related to configuration management, tools, best practices, and generally how to get to the pub by 4 o'clock.

This is the first meetup. Hopefully we can get organized, get to know each other, and decide on what the goals of the group should be.

So if you are interested in automation, configuration management, cloud computing, and large scale computing environments, come join us for a few drinks and some lively chatter.

Please RSVP by sending an email to [email protected] so that we can get a bigger room if needed.

OpenEmbedded

Getting started in embedded Linux development can be intimidating. Every hardware device vendor seems to have its own embedded Linux distribution and way of developing for it. OpenEmbedded (OE) is a framework for creating highly customizable embedded Linux distributions. It provides a well-designed build system and cross-compilation environment to developers, and a robust package management system for setting up and maintaining your embedded Linux system.

Find out why OpenEmbedded is taking the embedded world by storm and improving the lives of embedded Linux developers.

Scott Garman is a Linux Software Engineer at Russound, a leader in multi-room audio systems, which allow you to enjoy music throughout your home.

Local users of Puppet and anyone interested in configuration management are invited to the downtown Portland Reductive Labs offices for food, drink, and a demonstration of the Puppet Dashboard.

This time around Cody Herriges, the Lead Unix Administrator from Portland State University's Computer Action Team which provides computer infrastructure for the Maseeh College of Computer Engineering and Computer Science will be presenting their puppet implementation. An ever growing and re-factored monstrosity of genius. If you have ever thought about implementing Puppet but wanted to see real use cases before biting the bullet you will get it here.

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.

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.

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. Vincent has spoken in various forums on this topic, co-authored 3 books, 10 papers, and several specifications in this area.

Apple's iOS devices have become a revolution. Whether you use a Windows, Unix or Apple server platform, these devices are becoming the industry standard for such jobs as POS and CRM. They have even managed to overtake the long standing leadership position from Blackberry devices. Apple's MacBook Pro, MacBook Air and iMac product lines are also gaining traction among business professionals. You see the easily recognized Apple logo consistently in TV shows and movies.

I will discuss the role of Apple products in the modern business landscape focusing on how they and their uses of the iCloud technology have 'changed the game' concerning daily computing. I will provide a series of examples of how iOS mobile devices are currently being used in the small business sector and how big business is beginning to get on board and why. Then I will outline the challenges facing IT support professionals concerning this rapid adoption of relatively new technology into long standing corporate environments and systems. These challenges include integration, security, deployment, app development/distribution and keeping up with Apple's constant flow of new products and software updates.

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.

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.

Bio: Brian Martin is the chief consultant for Martin Consulting Services, Inc. Martin Consulting has provided system administration services in Unix, Linux and Windows systems in the Portland metro area and across the country since 1996. Brian is a frequent attendee at PLUG. His past presentations include VMWare, production grade scripting, disaster recovery experiences, Linux containers, and logical volume management.

Where: Free Geek, 1731 SE 10th Avenue, Portland
When: Tuesday, November 19th, 2013 at 7pm
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.

Bio:

Rogan Creswick develops unique tools and techniques for software development and security analysis at Galois, Inc. His research interests focus on improving the state of the art in software engineering tools and user interfaces. His experience also reaches into the areas of user interface automation and customization via integrated assistants and automated documentation aides at IBM Research. He has striven to provide natural interfaces to ease communication with complex and semi-sentient agents through existing tools that have already become trustworthy and familiar to their users.

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.

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.

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.

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.

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.

If you’ve wanted to run your own mail server, but held back because it sounded complicated, fear no more. In mere days you too can have a GMail-like experience. 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. All of this is done on FreeBSD but can also be done on others such as Linux, Solaris, or even Irix (if you love pain).

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.

Learn about the latest developments in FreeBSD virtualization including EC2 and Hyper-V guest support, Xen Dom0 and DomU support and bhyve, the native FreeBSD Hypervisor.

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

Who: Michael Dexter
What: Block Storage Device Life Cycles
Where: PSU, 1930 SW 4th Ave. Room FAB 86-01 (Lower Level)

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.

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:

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.

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.

You probably have a good sense of data protection in the sense of "backups" but alas, there is more to it. This talk will cover ten key aspects of Data Protection and discuss open source technologies that address them.

Is your data...

1. Integrous – Maintaining integrity and consistency
2. Resilient – Resistant to mechanical failures/outages
3. Versioned – Accessible in a previous state
4. Replicated – “Backed up” to local and remote locations
5. Archived – Versioned and replicated for long-term storage
6. Secure – Resistant to unauthorized theft or destruction
7. Private – Available for authorized purposes only
8. Available – Accessible in a timely manner
9. Usable – Equally available now and in the future
10. Compliant – with legal and regulatory requirements

Bring your questions and experiences for a livid^H^H^H^H^H vivid and vibrant discussion.

Fedora Atomic Host: Your Next Linux

Our current model of RPM-and-config-management for Linux systems has done well for us over the last decade and more, but is starting to show its age. Come learn about Atomic Host, which is a new model for managing software and maintenance for large clouds of hosts.

Josh Berkus of Red Hat will explain the Atomic Host "ostree" model for binary updates, and how that ties in with container deployments of applications. He will demo deploying and updating a cluster of Atomic Hosts running OpenShift, and answer questions about this architecture. He'll then speculate about what the future could hold, in the form of modularity, Flatpaks, and more.

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.

Most medium to larger businesses use central PBX phone systems to save money on telephone lines. Over the last decade the business PBX has gradually evolved towards Voice over IP hardware and away from traditional digital phones. Proprietary VoIP PBX systems such as Panasonic, Cisco and Mitel are available but costly. This presentation will cover how companies can take advantage of open standards such as SIP and LDAP and software such as Asterisk to have an inexpensive PBX that has features of the large, expensive and proprietary systems. An Asterisk system will be demonstrated and used as a sample system for the presentation.

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.

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.

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.

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.

I am a UTF-8 neophyte trying to fix a broken program that now needs to use UTF-8. I've spent decades porting large programs to new environments. Now I'm planning on integrating a large library to a small program. ATTENTION!

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.

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.

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.
