    Rentrak Hackathon

    Rentrak - Downtown

    The Rentrak Hackathon is a gathering of laptops and laughter. Classically, we all sit in a square and type words onto a keyboard that then get turned into a "computerized program". It's a good chance to work on your personal projects, learn what your peers are up to (computer-wise), figure out what the best programming language is, and/or say the words "I don't have anything to work on" or "I forgot my laptop". This event is very informal, and there is no specific project we'll be focusing our efforts on.

    Food and refreshments are served. RSVPing to ssw@rentrakmail.com is appreciated, but not required.

    Come check out Rentrak's new downtown office. Everyone is welcome to join us!

  • Secret Knowledge Exchange


    This is Secret Knowledge's Un-Workshop. There's no topic, just a mission.

    It's about getting you the resources, skills, tips, creative advice, tech help, or buoying encouragement you need right now. Come, and get it.

    Getting the most out of Secret Knowledge Exchange

    It's an un-workshop. That means it doesn't have a topic. Participate by bringing requests or a topic suggestion for the group. Engage and help each other. If you have the answers someone needs, share.

    We guarantee to make it worth your time, each and every time.

    Some ideas

    We hope this example list will help you as you consider what requests to bring to the workshop. We're including it to inspire you, not limit your options.

    • Bring that pesky technical device, computer program, or other doodad that you're having trouble figuring out. Ask for help. (bring the manual if you have it)

    • Talk about the state of your career, what your goals are, and ask for advice on how to break out of a rut.

    • Bring something you're working on, ask for some feedback.

    Free / Suggested donation ($5 - $15)

    Let us know you're planning to attend. Registration is free (and optional).

    SWePoCoNi (The West Side Strikes Back)

    Commodore Lounge

    Southeast Portland Coder's Night was a glorious gathering of folks. Many nachos were had while discussing various projects. This died out as Side Door stopped being open after 7pm.

    A few of us have tried various venues but haven't been happy with many of them. One venue a few of us would hang out at after user groups is the Commodore Lounge on SW 17th and Burnside. It has wifi, delicious food, and a wide range of drinks. The power situation could be better but we are sure we can improve this with time.

    So, come along, have a drink and some food with us as we embark on the next stage of Portland Coder Nights. The time is a guideline, show up when it makes sense to you and leave when you want or need to. These are just the hours we've seen work for a majority of folks in the past.

    Portland Ruby Brigade monthly meeting

    New Relic

    We'll have pizza & beer starting at 6pm, so stop by early if you want to have dinner and socialize before the presentations.


    After presentations we'll have more socializing time.

    Thanks to New Relic for providing the venue and beer, pizza & snacks this month!

    ARRIVING BY BIKE? Cyclists are welcome to park their bikes in the New Relic office. Bikes are not allowed in the building lobby, however, and must use the freight elevator. To get your bike up to the 29th floor, enter the building's parking lot by going down the ramp at 5th and Pine. Go past the booth -- no need to pick up a ticket -- and turn right. Go straight until you almost run into the elevator lobby, then go right again. On the back side of the elevator block you'll see a beat up pair of double doors marked "freight elevator." You can get up by buzzing in with the intercom, and saying you're here for New Relic. Ride on up to the 29th floor, you'll easily find the bike parking.

    ABOUT THE GROUP: The Portland Ruby Brigade, also known as pdxruby and pdx.rb, is a user group for Ruby programmers in the Portland, Oregon area. The group welcomes all programmers interested in the language and its implementations, tools, libraries and frameworks, such as Ruby on Rails. The group has been meeting since August 2002 for presentations, demos and discussions. Every month 35-75 people come together to share their knowledge, projects and enthusiasm for Ruby. If you'd like to present or have a topic you'd like discussed, please post to the mailing list. The group usually meets on the first Tuesday of the month, "Ruby Tuesday" -- see you there!

    Whether you are new to coding or experienced in coding and want to help others learn, please join us! Bring your laptop and desire to learn (and/or teach!).

  • Science on Tap - Lasers and Landslides

    Science on Tap is a science lecture series where you can sit back, enjoy a pint, and laugh while you learn. Listen to experts talk about the science in your neighborhood and around the world. You don’t have to be a science geek to have fun—all you need is a thirst for knowledge!

    COST: $8 online advance tickets, $10* suggested cover at the door

    FOOD & DRINK: Beer, wine, popcorn, and snacks available. You’re welcome to bring food into the theater with you.


    From flying machines to computers to lasers to lidar, technology has revolutionized the study of earth science. That’s good news for Oregon, where scientists at the Department of Geology and Mineral Industries are using lidar to learn more than ever before about the widespread geologic hazard of landslides.

    Engineering Geologist Bill Burns will talk about the destructive power of landslides, risks for Oregon’s people, places, property – even our beer – and how lidar is making a difference.

    *A note on the suggested cover at the door: Science on Tap is mostly supported by money collected at the door. It is committed to offering educational opportunities to adults who want to learn, so if $10 is a hardship for you, please come anyway and donate what you can.

  • Portland Bitcoin Group

    Portland Bitcoin Group will be meeting here on the first and third Tuesdays at 8:00 P.M. We hope that this can become a venue for bitcoin enthusiasts to meet and trade bitcoins and experiences.

    1 Million Cups - Portland

    Forge Portland

    1 Million Cups (1MC) is a simple way to engage entrepreneurs right here in Portland. Each week, the 1MC program offers local entrepreneurs an opportunity to present their startups to a diverse audience of mentors, advisors, and entrepreneurs. Presenters prepare a 6 minute educational presentation and engage in 20 minutes of feedback and questioning after they present. Entrepreneurs gain insight into possible ways they can improve their businesses, gather realtime feedback, connect with a community that truly cares about their progress, and walk away feeling like they have advanced their business. The audience also learns a great deal from the presentations. Whether this is through passively listening or deeply engaging with the entrepreneurs, there is much to learn every week from these dynamic and diverse communities.

    The program takes place every Wednesday morning from 9:00-10:00am at 5257 NW Mlk Blvd. Suite 201

    1 Million Cups is a program run by entrepreneurs for entrepreneurs.

    For additional updates, please follow us on Twitter @1MillionCupsPDX and connect with us on Facebook.

  • Decision Architecture: Building Robust Business and Technology Decisions -- Oregon Enterprise Architects

    Decision Architecture tackles the tough problem of aligning the best decision-making techniques to the problem at hand and the resources available. It helps structure information to build, vet and reuse critical decisions. It incorporates risk, uncertainty, and stakeholder concerns into business, application and technical decisions.

    Decision Architecture matches tried and true decision-support methods to each decision requirement. It extends these methods as needed with state-of-the-art analytical methods and makes the best use of modern team building best practices to enfranchise all stakeholders. It helps organizations build decision repositories so that decisions can be reused.

    If you answer yes to any one of the following questions, then this event is for you!

    Does your organization:

    • Revisit decisions that were declared final? • Make team decisions by edict or by the loudest voice? • Have little confidence in decisions based on uncertain information? • Not justify, record, or reuse decisions? • Have projects that are over budget and time with reduced performance?

    Guest Speaker:

    David Ullman , Decision Architect, EA Principals

    Event Details:

    When: Wednesday, December 3rd Time: 3:00 – 6:00 PM Location: TBD Free to attend but registration is required

  • Write The Docs PDX: An Introduction to DITA

    During our November Meetup on RESTful API documentation, we heard about one system where automated documentation is processed through DITA, the Darwin Information Type Architecture.

    For December, we will have a joint meetup with PDX DITA, our local DITA users group.

    For food, we'll try something different this time, a potluck. Jive Software will provide beverages. Bring what you think is appropriate for the season. You don't have to cook; I might bring something from Safeway.

    DITA is an XML-based model for single-source documentation.

    Imagine writing your documentation with XML tags such as the tags that surround this paragraph.

    Imagine a world where you don't have to fight with word processing software to get the output you want!

    For anyone who is used to WYSIWYG tools such as Microsoft Word, DITA is different. With DITA, you write content once and use it in multiple publications, without having to worry about formatting. You can output the same content to a variety of outputs, such as HTML, PDF, ePub, and many others. We’ll discuss these and the many other benefits of using DITA, as well as how to get started.

    If you want to read up before the meeting, here’s a good overview of DITA: http://www.learningsolutionsmag.com/articles/524/what-is-dita-and-why-should-you-care

    Leona Campbell and Melanie Jennings of Jive Software will be our presenters. They’ll be sure to leave plenty of time for Q&A.

  • Learning Erlang made me a better engineer and architect


    Nathan Aschbacher throws down on his favorite Erlang topic:

    Learning Erlang made me a better engineer and architect.

    Even if you don't think you have a use-case for Erlang, don't have an interest in functional programming, and find reading Prolog inspired syntax directly proportional to your increased consumption of Excedrin... according to Nathan Aschbacher (currently Chief Architect at Snapflow and previously Principal Consulting Architect at Basho) you should learn Erlang anyway.

    Nathan will be presenting on his path to Erlang and functional programming, his initial disdain, his later begrudging respect, and finally his eventual love and nostalgia for all things Erlang-y.

    Join us and share in the conversation.

  • PDX Big Data Discussion Group

    "No talks. You may opt to take up to 60 seconds to complain about Big Data. One paper per month, no obligation to read it."

    We'll start by letting anyone who wants to take up to a minute to tell us what they've been doing with data lately.

    This month's paper is Materialization Strategies in a Column-Oriented DBMS by Abadi etal. Read it or don't - the goal is just to have something to start conversations. "Did you read the paper?" will do nicely.

    Mention @PDXBigData on Twitter with the link to the full paper to suggest papers for future sessions.

    There will be pizza.

  • OWASP Chapter Meeting

    New Relic

    Joseph Arpaia, MD will be presenting: Hiding in Plain Sight: A Mnemonic Method For Creating Secure Passwords

    The human brain is not suited to recalling secure passwords composed of random sequences of characters especially if they are not used regularly. Humans are excellent at recalling sentences, even years after learning them, e.g. nursery rhymes, song lyrics. This ability can be used to create a mnemonic method for generating a large number of passwords from one remembered passphrase, even if the passphrase and the associated characters are not kept secret.

    Joseph Arpaia received his BS in Chemistry from CalTech and his MD from UC Irvine where he also did research in electrophysiology and applications of chaos theory to psychiatry. He is a psychiatrist in private practice in Eugene, OR and applies heart rate variability analysis in his work with patients. He also teaches applications of mindfulness meditation to psychotherapy at the University of Oregon and is the co-author of Real Meditation in Minutes a Day. He has a long-standing interest in passwords and security which dates back to his experience at age 8 when he came up with a Vernam cipher in response to a challenge by his father to encrypt a text message.

    The Open Web Application Security Project (OWASP) is a 501c3 not-for-profit worldwide charitable organization focused on improving the security of application software. To sign up for future meeting notes and to discuss security topics with local gurus, sign up on the OWASP Portland mailing list: https://lists.owasp.org/mailman/listinfo/owasp-portland

    Meetings are free and open to the public.

  • Rose City SPIN: Is Data Dated? by Arnie Rowland

    Biggi Plaza


    In the past decade there has been an incredible explosion in the amount and kinds of data being collected, captured, combined, complied, concentrated, and subsequently culled. Companies are being stretched financially to collect, store, sift through, and find value from their considerable investments in data. On Premises Servers, Cloud Servers, Data Redundancy Sites, High Availability options, Back-up infrastructures and off sites storage –all with the constant fear of losing control of the data. We all know that Hackers are everywhere, working to find value in anyone’s security lapse, trying to find a way in. But do you realize that most economic damage comes from avoidable accidents, misuse, and misappropriation of data, from within the organization?


    Arnie is a long serving Microsoft SQL Server MVP, has been a Subject Matter Expert (SME) working on SQL Server from version 2000 up through version 2014 training courses, and has recently been involved as a SME with the development of the SQL 2005 through SQL 2012 Microsoft Certification Exams. For over a decade, Arnie has also been a Microsoft Certified Trainer, and has served as a technical editor for several publishers, including multiple SQL Server titles in the Microsoft Official Curriculum. Arnie has served as adjunct faculty at both University and Community College. Clients include Fortune 500 and Multi-National companies, Federal and State agencies, foreign governments, nationally recognized training facilities, and local enterprises –both public and private.

    Arnie is a Senior Moderator on the MSDN and TechNet SQL Server related Forums, and is a founding member of the TechNet Wiki Governing Council. Arnie is founder, and current president of the Oregon SQL User group, co-Founder of the Portland Code Camp, and has been the lead facilitator for SQL Saturday Oregon events. In addition to being a pilot and flight instructor, Arnie holds post-graduate degrees , is an avid bicyclist and sailor, and plays racquetball competitively.

The setup is informal, no presentations, and we are just trying to meet fellow ruby geeks in the community. Also, working remote or in an office space cube needs a change of scenery each week. (Please note: It is totally cool to work on non ruby languages with us too)

  • AgilePDX Dntn Pub Lunch: Why the Board Matters in Kanban

    As pitched in October, we have Matt Mayer coming to talk to use in December. Remember, anyone can pitch a talk to the group just by showing up and tossing in your idea when we vote on upcoming topics at the end of the hour.

    At Monsoon, we’ve tried and tested Kanban—and we’ve learned a lot! Our microservices team is driven to do fast, small changes to deliver bug fixes and features to production fast. Interdependencies between services mean a single service going down causes customers and Monsoon to lose money. Using a physical Kanban board meant the difference between guessing where bottlenecks were versus identifying the problem, targeting it and applying multiple forces to eliminate it. It also makes large tickets stand out so they can be analyzed and sliced into smaller tickets for faster delivery.

    Matthew Mayer has been programming professionally since 2006, with an emphasis on performance and complex problem solving. He’s worked with a variety of technologies from ASP.NET web applications to .NET installed products to cloud services in Go, quickly providing data for customers worldwide. He developed an increasing interest in integration tests and tools for that end, such as cucumber and Docker. He advocates for close integration with QA counterparts so programmers can focus on delivering early and often, lowering barriers to entry for new team members.

    RSVP's to the AgilePDX Yahoo list or to Jean@azuregate.net are much appreciated. We occassionally have very large turnouts, and its great to be able to warn the wait staff.

    Look for us in the back. We start on time and end on time so you can get back to making the world safe for agilists everywhere. Yes, the beer flows and so does the pub grub.
