    Portland Linux/Unix Group General Monthly Meeting:OpenWISP, an Open Source Network Management System for OpenWrt
    linux

    There are many commercial wifi access point (AP) controller setups, ie a single management interface to control multiple APs. Until recently there wasn't a FLOSS method of doing this. OpenWISP (https://openwisp.org/) is a modular and programmable Open Source Network Management System for OpenWrt. In this presentation we will go over the simple installation and setup process, including connection to multiple OpenWrt access points.

    Bio:

    Eldo Varghese is a constant nomad that has settled in Portland as of 3 years ago. Recently turned 40 and looking for more community in his old age. Currently works in an SRE/Devops role at a small non-profit academic journal (https://plos.org). Involved in Linux community in some fashion since 2007, and have used OpenWrt for the past 15 years.

    PDXRust Meetup

    Meet up with fellow Portland-area Rust programmers, give a lightning talk on your own project, find something interesting to collaborate on, or just enjoy talking shop with your fellow Rustaceans!

    This is our first meeting since the pandemic! (Remember the pandemic?) We don't have any big topics planned to present, so this will just be a hack night. Brainstorming talk ideas for future meetups is definitely on topic.

    Kindly hosted by Portland State University, we'll be meeting in Computer Science Conference Room FAB 086-01. Calagator has an entry for this venue: https://calagator.org/venues/202394217

    (I'm a bit unclear on the security details; we may have someone at the door to let people in, in which case arriving late might be difficult, since we'd of course like that person to come down and join the group eventually. When I have more details I'll update this. -JimB)

    Portland Linux/Unix Group: Reading wireless temperature sensors with RTL-SDR and rtl_433

    Who: Russell Senior What: Reading wireless temperature sensors with RTL-SDR and rtl_433

    When: Thursday, January 2nd, 2020 at 7pm

    Stream: http://pdxlinux.org/live

    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.

    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!

    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.

    Who: You!
    What: Contending With Our Culture of Discouragement

    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.

    Why: The pursuit of technology freedom

    While I will explain about what DBIx::Class::Events does and how it works as well as some of the underlying technologies it builds on, this talk is primarily about open source contributions being driven by the folks in a company who care about them and how it is up to those people to provide the resources and knowledge to everyone else in order to create an open source culture in the workplace. 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.

    Many will head to the Lucky Lab at 1945 NW Quimby St. after the meeting.

    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).

    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

    Heather Wilcox has spent 24 years working and learning in the software industry, choosing to focus primarily on start-up and small companies. As a result, she has had a broad range of job descriptions which include, but are not limited to: Tech Support Engineer, IS Manager, Technical Writer, QA Engineer, QA Manager, and Configuration Management Engineer. This has given Heather a wide range of experiences to draw from in her current roles as a Senior Quality Assurance engineer and Scrum Master.

    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.

    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.

    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.

    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.

    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.

    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.

    Bring your Net Neutrality questions!

    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.

    The OAuth 2.0 authorization framework has become the industry standard in providing secure access to web APIs. OAuth allows users to grant external applications access to their data, such as profile data, photos, and email, without compromising security. However, OAuth can be intimidating when first starting out. In this talk, Aaron Parecki will break down the various OAuth workflows and provide a simplified overview of the framework, highlighting a few typical use cases.

    About Aaron

    Aaron Parecki is the editor of the W3C Webmention and Micropub specifications, and maintains oauth.net. He is the co-founder of IndieWebCamp, a yearly worldwide conference on data ownership and online identity.

    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.

    Bonus: Discussion about the future of PLUG Advanced Topics and other PLUG housekeeping, planning and fun!

    Computer Science Colloquium: Drucker-Prager Elastoplasticity for Sand Animation

    Title: Drucker-Prager Elastoplasticity for Sand Animation Speaker: Joseph Teran, UCLA

    Abstract: We simulate sand dynamics using an elastoplastic, continuum assumption. We demonstrate that the Drucker-Prager plastic flow model combined with a Hencky-strain-based hyperelasticity accurately recreates a wide range of visual sand phenomena with moderate computational expense. We use the Material Point Method (MPM) to discretize the governing equations for its natural treatment of contact, topological change and history dependent constitutive relations. The Drucker-Prager model naturally represents the frictional relation between shear and normal stresses through a yield stress criterion. We develop a stress projection algorithm used for enforcing this condition with a non-associative flow rule that works naturally with both implicit and explicit time integration. We demonstrate the efficacy of our approach on examples undergoing large deformation, collisions and topological changes necessary for producing modern visual effects.

    Bio: Joseph Teran is a professor of applied mathematics at UCLA. His research is focused on numerical methods for partial differential equations arising in classical physics. This includes computational solids, computational fluids, multi-material interactions, fracture dynamics and computational biomechanics. Exciting applications include computer graphics and movie special effects at Walt Disney Animation. Professor Teran was a recipient of a 2011 Presidential Early Career Award for Scientists and Engineers (PECASE) and a 2010 Young Investigator award from the Office of Naval Research. In 2008, Discover Magazine named him one of the 50 “Best Brains in Science” which lauded him and other young scientists as “young visionaries who are transforming the way we understand the world”.

    Bitcoin - A Technical Introduction.
    bitcoin

    "Bitcoin is the world's first decentralized, peer-to-peer, digital currency and payment system. At its heart is an open source value-transfer protocol that facilitates currency transfers among users without relying on a trusted third party. The protocol employs provable-cryptography to prevent counterfeiting, censorship, double-spending, and account seizures.

    We'll learn how the bitcoin protocol works, discuss some of its strengths and weaknesses, and dispel some common misperceptions. No prior knowledge of cryptography is required, but a basic understanding of mathematical functions (ie: surjectivity, injectivity, domains, images, preimages, etc) will be assumed."
