PDXPUG August Meetup: PostGIS

When: 6-8pm Thursday August 15, 2019
Where: PSU Business Accelerator (Parking is open after 5pm.)
Who: Jackson Voelkel

Jackson will discuss the basics of GIS, and the current environment in which enterprise spatial analytics are performed. Considering the many pitfalls of this current system, he will discuss how FOSS tools – especially PostgreSQL/PostGIS – are vitally important for modern spatial analytics. In addition to the PostGIS extension, Jackson will talk about network routing using the PgRouting extension and the interface between R and PostgreSQL. This talk will act more as a showcase of GIS and “spatial SQL” within PostgreSQL than it will nitty-gritty database development.

Jackson Voelkel is a Health Data Analyst on Kaiser Permanente’s GIS Team as well as an Adjunct Professor of Geography at Portland State University. He focuses on developing infrastructure for and performing advanced spatial analytics across healthcare, environment, urban planning, utilities, and econometrics. He teaches courses on advanced spatial analytics in R as well as spatial database design with PostgreSQL/PostGIS.

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.
