PDXPUG April Meetup: Postgres with non-blocking IO and Scala

2019 April 18th Meeting 6pm-8pm

Location:

PSU Business Accelerator
2828 SW Corbett Ave · Portland, OR
Parking is open after 5pm.

Speaker: Grant Holly

This month I will be demonstrating using non-blocking IO database access using Scala and the Slick library.  No really, the library is called Slick AND it is very cool to use.  Slick and Scala are great for working with Postgres with either straight SQL, or using the FRM (that’s a Functional Relation Mapper like in functional programming).  After Hannah gave a great talk talk about Python, Postgres, and ORMs, I got to thinking that I could do a language and ORM talk.  Thanks Hannah, that was great.

Hi, it’s me still Grant.  I work at New Relic as an engineer on the database engineering team.  I’ve been using Postgres in production since 9.2 and have been using and enjoying Scala for about two years having worked on a couple of production high throughput applications.

PDXPUG: March Meetup: Let’s talk databases in python!

2019 March 21 Meeting 6pm-8pm

Location:

PSU Business Accelerator
2828 SW Corbett Ave · Portland, OR
Parking is open after 5pm.

Speaker: Hannah Stepanek

Let’s talk databases in python! What’s an ORM? Is there a way to write database queries so that they are compatible with multiple types of databases? How do you make database changes (such as adding a new table or a new column) safely? What is a connection pool and why is it useful? What are some things that can go wrong when operating at scale? In this talk we’ll take a deep dive into how the python libraries sqlalchemy and alembic make managing production databases simple, efficient, and painless so you can get back to feature development.

Hannah has been working in industry for over 6 years as a python software engineer. She currently works at Hypothesis, a web application for annotating web pages and pdfs. In her spare time she enjoys riding her horse Sophie and playing board games.

PDXPUG: February Meetup: Temporal Databases: Theory and Postgres

2019 February 21 Meeting 6pm-8pm (Note: Back to third Thursday this month!)

Location:

PSU Business Accelerator
2828 SW Corbett Ave · Portland, OR
Parking is open after 5pm.

Speaker: Paul Jungwirth

Temporal databases let you record history: either a history of the database (what the table used to say), a history of the thing itself (what it used to be), or both at once. The theory of temporal databases goes back to the 90s, but standardization has only just begun with some modest recommendations in SQL:2011, and database products (including Postgres) are still missing major functionality.

This talk will cover how temporal tables are structured, how they are queried and updated, what SQL:2011 offers (and doesn’t), what functionality Postgres has already, and what remains to be built.

Paul started programming on a Tandy 1000 at age 8 and hasn’t been able to stop since. He helped build one of the Mac’s first web servers in 1994 and has founded software companies in politics and technical hiring. He works as an independent consultant specializing in Rails, Postgres, and Chef.

January 2019 meetup and new location

When: 6-8pm Thursday January 24, 2018
Where: New Relic
Who: Mark Wong
What: Multi master replication

Happy new year everyone.  As always the new year brings changes.  For instance, we are moving meetup locations.  We will be meeting at PDX Code Guild (https://pdxcodeguild.com/contact_pdx_code_guild/).  They are located at the Business Accelerator at 2828 SW Corbett Ave (https://www.google.com/maps?q=2828+SW+Corbett+Ave,+Number+208+Portland,+OR+97201).  I think you will find the new accommodations quite nice.  And while the location may have changed, some things have not.  We will still have food and beverages available and interesting topics of discussion with other interesting people.

Mark Wong will be giving a talk on the always-vexing topic of multi-master replication with Postgres.

Mark leads the 2ndQuadrant performance practice as a Performance Consultant for English Speaking Territories, based out of Oregon in the USA. He is a long time Contributor to PostgreSQL, co-organizer of the Portland PostgreSQL User Group, and serves as a Director and Treasurer
for the United States PostgreSQL Association, and a pretty nice guy too.
