in person meetup

Portland Java User Group

Join us for the PDX JUG July Meetup where we will dive into the world of Structured Concurrency. Structured Concurrency is a preview feature in Java 21 and will simplify the common scatter-gather kind of pattern.

Tyler Van Gorder is our speaker, he has previously spoken about Virtual Threads in Java, and Structured Concurrency is a great complement to Virtual threads. In Tyler's words:

"Simplify concurrent programming by introducing an API for structured concurrency. Structured concurrency treats groups of related tasks running in different threads as a single unit of work, thereby streamlining error handling and cancellation, improving reliability, and enhancing observability."

We will briefly recap how virtual threads work and then explore how related tasks can be grouped as a single unit of work. We will cover the different shutdown strategies and examine how the programming model compares to similar functionality using a reactive framework."

Don't miss this opportunity to network with fellow Java enthusiasts, share your experiences, and learn from each other. Whether you are interested in web development, software development, or JVM languages, this meetup is open to anyone who is passionate about Java.

Many neurodivergent professionals work in the fields of accessibility and user experience. Yan Vishnepolsky joins us today to discuss his career as a neurodiverse user researcher. He will talk about aspects like living abroad as a UX professional, launching a podcast, and the benefits and challenges of being neurodiverse in design tech.

Event begins at 6:00pm; join early starting at 5:45pm for networking.

About the presenter

Yan's family knew from an early age that he was neurodiverse. As such, he attended BOCES Gifted Special Education, a program in upstate New York for neurodivergent children, throughout most of his school years. A couple of years after college, he launched a UX agency in India and lived there for nine years. While in India, Yan learned Hindi and Indian culture, teaching him firsthand the impact of different perspectives. Also in India, he met his wife, an Iranian expat studying as a pharmacist. After marriage, Yan moved back to the US, where he pursued a career specific to user research. In the last few years, Yan has been particularly interested in the impact of AI on the future of user research work (and vice versa). Last year, he started speaking publicly about the impact of neurodiversity on his career.

Lecture Details Sometimes when we share research findings, we hear back, “We already knew that.” In this talk, I’ll examine why that happens, and what we can do about it. Sometimes, it’s a cognitive bias, called hindsight bias and also known as the “knew it all along” phenomenon. But there are other causes and we can adjust our approach to research to try and limit this all-too-common challenge.

Portland Design Thinkers is thrilled to announce our next event with Damon Gaumont: Turning Empathy into Action – This Is How Digital Products Attain True Success

Turning empathy into action in digital product experiences is crucial for creating products that resonate with users, provide value, and foster positive relationships between users and businesses. It not only leads to better user satisfaction but also contributes to the success and reputation of the product and the company behind it. In this talk, Damon will cover why it is so important, various methods to achieve it, how to measure it, and how to ensure it is continually improved.

About our speaker: Damon currently guides brands accountably through the creation of digital experiences by tapping his extensive background and expertise in brand building, creative strategy, and experience design.

Don't miss this great opportunity to learn and network!

Bio: Semih Salihoğlu is an Associate Professor and a David R. Cheriton Faculty Fellow at University of Waterloo. His research focuses on developing systems for managing, querying, or doing analytics on graph-structured data. His main on-going systems project is Kùzu, which is a new graph database management system that integrates novel storage, indexing and query processing techniques. He holds a PhD from Stanford University and is a recipient of the VLDB 2018 Best Paper and the VLDB 2022 Best Experiments and Analysis Paper awards.

Abstract: In this talk, I will present the Kùzu graph database management system (GDBMS) that we are developing at University of Waterloo. Datasets and workloads of popular applications that use GDBMSs require a set of storage and query processing features that relational DBMSs (RDBMSs) do not traditionally optimize for. These include optimizations for: (i) many-to-many (m-n) joins; (ii) cyclic joins; (iii) recursive joins; (iv) semi-structured data storage; and (v) support for universal resource identifiers. Kùzu aims to integrate state-of-art storage, indexing, and query processing techniques to highly optimize for this feature set. I will start by presenting the overall vision of Kùzu and then talk about the novel join operators in the system that performs joins using compressed factorized representations of intermediate tables. Kùzu is actively being developed to be a fully functional open-source DBMS with the goal of wide user adoption and under a permissible license.

Want access to some hardware, electronics and sensors to play around with Nerves on.

Want to discuss the latest happenings in the community.

Need somewhere away from home to work on a project.

Just want something social to do.

We're still trying to lock in the venue for the in-person events and venues may change over time, as might the rules regarding masking depending on peoples' comfort level.

For the most part, the mask rules will follow the same restrictions as the venue and will evolve based on current trends of the virus and feedback from the community. If you're interacting with or sitting next to someone, and they would prefer for you to also be masked while nearby, please be considerate of their request.

Future Meeting Cadence

We'll be switching to the following format moving forward:

Last Tuesday of the month remains a virtual-only event, combining both the Portland and Seattle groups and anybody else who would like to join us virtually. This event has been mostly a "demos on demand" during the pandemic but will start to move back toward a 50/50 split with a pre-announced presentation for part of the event. If you have something you'd like to talk about, let the event coordinator know (see Event Coordinator Contact below). Future event dates will be: Apr 26, May 31, Jun 28, and Jul 26.

Two weeks before the meeting on the last Tuesday (third from last Tuesday), will be an in-person hack and help night in Seattle. Future event dates will be: Apr 12, May 17, Jun 14, and Jul 12.

The following night after the Seattle hack night will be an in-person hack and help night in Portland. Future event dates will be: Apr 13, May 18, Jun 15, and Jul 13.

Sponsorship

If you or a company you work for would like to host an event, or sponsor food, beverages or venue costs, please let me know! (see Event Coordinator Contact below).

Presented by Ryan Wright, Founder, thatdot.com Abstract

This talk will introduce Quine: a brand new open source “streaming graph interpreter” meant as a new fundamental infrastructure component to address major challenges in data engineering and simplify enterprise data pipelines.

Quine fits in between the world of databases and stream processing systems. As data streams in from Kafka, Kinesis, etc., Quine builds it into a graph. Then using “standing queries”—queries that live inside the graph and efficiently propagate—it finds matches to complex patterns in the graph and streams the results out right away. Quine maintains a stateful representation of all data streamed through (like a database) so that complex results are built from the combination of new streaming data and potentially very old data—all without having to manage any time windows. Since the graph is fully versioned, you can always query for what the data used to be, at any historical moment. Quine is meant to be a complete package of everything that lives between two Kafka topics: high-volume events stream in, and highly-meaningful interpreted results stream out.

In this talk, we will explain the how Quine works under the hood, discuss some of the interesting and brain-bending challenges we had to confront in order to create it, and show some uses cases to illustrate why it’s important for modern data pipelines. Quine implements a property-graph data model on top of an asynchronous graph computational model. It’s like Pregel with Actors. Each node is capable of performing arbitrary computation, so we can bake in some powerful capabilities deep in the graph; and then package it up for easy use into user-contributed “recipes” available in the Github repo. Quine is free and open and the repo will be publicly available in February, and actively supported by thatDot and the community.

Why We’ve Changed Our Name

DAMA PDX has been rebranded as Data PDX. You’ll notice both the updated website and logo. While a shift in name only, this update represents our goal as a Board to better tailor the meeting content, group direction, and cross-marketing of other user groups and local organizations. DAMA will continue to be our governing body and we intend to remain affiliated to the shared values of training and exposure to all things data management. Our goal is to promote the world of enterprise data management in Portland metro and SW Washington.

Our new mission statement: To promote conversations around modern, enterprise-ready solutions to data-driven professionals in the Portland metro area

Portland Linux/Unix Group General Meeting Announcement

Who: Russell Senior
What: Russell's Excellent High Altitude Balloon Adventure
Where: https://meet.jit.si/pdxlinux
When: Thursday, October 7th, 2021 at 7pm
Why: The pursuit of technology freedom

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.

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 policy in the users interests, while also hacking on router firmware. Since 2018, he's been involved in an effort to bring at-cost fiber infrastructure to the Portland metro area, Municipal Broadband PDX.
