OpenSQL Camp is an un-conference style get together for people interested in Open Source Databases. We are not focusing on any one project, and hope to see representatives from a variety of open source database projects attend. OpenSQL Camp is free and our target audience are users and developers, but others are encouraged to attend too. See the website to sign up, and to see the full schedule.

In early 2009, several developers from Relevance and Viget Labs got together and starting talking about technical conferences. As we discussed our past experiences at regional, national, and international events, we began to realize something: large conferences are wonderful for a lot of things, but we wanted something that met a different set of goals. We came up with Developer Day, which was designed to:

• Build lasting relationships among local peers
• Bridge distinct technical communities

After a year of Developer Days, however, we decided a new look was in order, and thus was born DevNation. We've still got the same ideals, but we feel that the DevNation name better reflects that vision (and it's easier to Google!)

Relationships

The general pattern for a large conference runs something like this: you fly to a city, go to the event, have a great time, meet lots of great people, and fly home. More often than not, you don't see those people again until the next big conference, and that's a problem. We wanted our event to be different, so it's intentionally local. Speakers and attendees are overwhelmingly local to the conference, so when you meet someone doing something cool, you can connect with them a week later for lunch without a problem.

Technology-Agnostic

Sure, there are events that draw a wide range of developers (e.g., OSCON), but even then people tend to segregate; the Pythonists go to their sessions, the Rubyists to theirs, and the PHP devs to theirs. By having only one track, we give everyone the opportunity to see what's happening in other communities.

Panel: Selena Deckelmann, Igal Koshevoy, Jeff Lavallee, David Wheeler

This will be a panel discussion about the ups, downs, ins, and outs of relational, row, key-value, and hierarchical data stores (simplistic buzzwordiness: SQL vs NOSQL aka ACID CRUD.)

The panel will discuss parallelism, scale, data integrity, normalization, business logic, ORMs, and performance. Some of the following might be addressed:

• why do you want a relational DB?
• why do you not want a relational DB?
• Membase, MongoDB, Redis, Cassandra
• Tokyo Tyrant, CouchDB, old school K/V (zodb, bdb)
• distinctions between "relational" and "row store"
• how filesystem settings affect the database
• how important is your data?
• common errors in SQL schemas or usage
• is count(*) supposed to be fast?
• efficiency vs speed vs parallel cleverness
• sharding
• what is "scale" and do you need it?
• massively denormalized, or massively normalized?
• ORMs, materialized views, indexes, and the query planner
• typical performance with small/large, simple/complex data sets

As always, the meeting will be followed by social hour at the Lucky Lab.

This month's topic: Semantic Datastores - the Other NoSQL

The NoSQL movement has given developers many more data storage options, each with their own design considerations and trade-offs. One of the quieter options, semantic data stores (also called triple stores or quad stores), provide an interesting hybrid of key-value and graph database features, while offering a data model based on a W3C recommendation (RDF) and a standardized query language (SPARQL) that will feel familiar to anyone experienced with unfashionable SQL.

This talk will cover the basics of data modeling with RDF and how to use the open source Jena Semantic Web Framework to add a semantic datastore to a Java-based Web application.

Hi, and welcome to the Portland Riak Group.

There are plenty of Riak Users in the PDX area, so it's time we had an official meetup. The team at AppFog was gracious enough to loan their space for the inaugural meeting, and a few members of the Basho team will be on hand to deliver pizza, beer, and stickers.

Here are the talks we have lined up:

7:15

Next Generation Searching with Yokozuna

Eric Redmond; Engineer, Basho Technologies

Riak Search was created to expand Riak's query options. It's worked well enough the past couple years, but it's time to move forward. Yokozuna is the next generation of Riak search, built on the solid Distributed Solr platform. We'll see a preview of what Yokozuna does, what it's going to do, and how that's a marked improvement from the existing Riak Search.

8:00

Riak & Node.js: The Hunt for Cheap, Easy Nines

Nathan Aschbacher; Developer, Coradine

Portland-based Coradine makes an innovative aviation application that helps pilots the world over. Riak powers a lot of this application. Nathan Äschbacher, developer at Coradine, will take you through:

• A quick history of our experience with Riak
• How it came to be we opted to use it at Coradine
• Some of the known hurdles we were going to have to overcome (like cloud deployment)
• Some of the development issues we've encountered
• Why Node.js was a good fit for us and interfacing with Riak
• Abandoning Redis in favor of Riak Memory-store for caching and 2i

COPIOUS is a user-centered digital experience agency. We build digital products with the user at heart and technology in our bones. We recently moved to a new office and now have a large space to host our TechTalks.

About TechTalks:

COPIOUSLabs TechTalks series meets every other Friday at 1pm at the COPIOUS offices. Our talks span artificial intelligence, new programming languages and techniques, computational linguistics, geographic data processing, systems and software architecture, augmented reality, network security, and more as proposed to the Copious engineering team.

About this talk:

Speaker: Andrew Gauger, Systems Engineer, Rejuvenation

MongoDB allows for abstracted data storage, so Andrew will talk about implementations of this flexible data design pattern. State machine and its ability to extend a document asynchronously gets highlighted. We will talk about data abstraction, and how to abstract structured data into a schema-less logger to perform validation.

In this TechTalk, Andrew will aim to describe clustering and replication as well as referencing and embedding in a simple language. The samples come fast but keep to explaining a simple topic. The talk diverges about how distributed database technology can be brought to firmware, how massive quantity small computing instances best leverage this technology, and what frameworks exist to leverage MongoDB on an upcoming project.

All are welcome to attend. If you have a talk that you'd like to suggest presenting, please email it to [email protected] along with a brief outline of what you'd like to cover.

Basho coworking office hours are every month. The meetup is during the day to come and hack on, deploy or just get a kick start on Riak, Riak CS or discuss NoSQL Solutions and Riak. Our first Coworking Office Hours will be from 9am until 11am on February the 4th. The regular meeting is scheduled for the same day at 7:00pm, generally we always meet at NedSpace unless otherwise mentioned in the meetup.

Neo4j is a powerful and expressive tool for storing, querying and manipulating data. However modeling data as graphs is quite different from modelling data under a relational database. In this talk, Michael Hunger will cover modelling business domains using graphs and show how they can be persisted and queried in Neo4j. We'll contrast this approach with the relational model, and discuss the impact on complexity, flexibility and performance.

We will also be showcasing our new tool GraphGist, and whiteboarding your particular use cases during the session. As always, beer/grub is provided by Neo4j.

*Do you want us to model your specific domain? Ping the PDX organizers and we will use your domain as an example during the meetup!*

Is the siloed internet over? It's too early to tell, but personal cloud is showing tremendous promise as a counter-paradigm that holds the promise of both providing most or all of the services that we currently enjoy and doing so in a way that is vastly more consistent with more stringent understanding of privacy and consent. While there are numerous countries making slow progress on the personal cloud front, none, as far as I know, are considering Riak as a data store for personal clouds. In this talk, I'd like to make the case for Riak as being an ideal technology for this.

The focus of this meeting will be the local users of Cassandra. In an effort to 'bootstrap' the group there will be a presentation of some of the ways iovation uses Cassandra in our various tests. Please come with additional thoughts about ways you might want to see your user group shape itself.

Developers, mobile app builders, NoSQL enthusiasts - join Orchestrate.io for discussions about databases, sharing war stories from production, and to have a little fun.

An Introduction To Data Modeling Techniques in Cassandra

Steve will discuss NOSQL, CAP Theorem, eventual consistency, and data modeling techniques in Cassandra. Following that will be a demonstration of some shell commands to create and query tables. We will discuss wide and narrow rows in Cassandra, storage options, and capacity planning. We will take a brief look at Titan, a graph database that can use Cassandra as a backing store. We will take a look at partition keys, clustering columns, time series data, and how these choices affect the storage and performance of the solution. We will discuss some of the real world challenges that come up, the trade offs associated with materialized views, plus compare and contrast this to a typical relational model. Time permitting we will discuss some real world use cases, and how Nike Social is using Cassandra to meet them.

Speaker

Steve Hall is a software engineer with over 15 years of experience. Steve is currently a full time engineer with Nike Digital, where he focuses on REST, social networks, and social network integration.

Full Stack Development with Java and NoSQL

In this session will talk about what is different about this generation of web applications and how a solid development approach must consider the latency, throughput and interactivity demand by users across both mobile devices, web browsers, and IoT. We will demonstrate how to include Couchbase, a NoSQL database, in such applications to support a flexible data model and easy scalability required for modern development.

Speaker:

Nic Raboy is a Developer Advocate for Couchbase in the San Francisco Bay Area. He has released several native and hybrid mobile applications to iTunes and Google Play and writes about his development experiences related to making web and mobile app development easier to understand. He has experience in Unity3D, Apache Cordova, Java, NoSQL, SQL, GoLang, and Node.js.

Businesses are discovering the untapped potential of large datasets and data streams through the use of technologies for big data processing and storage. By leveraging these assets they’re creating a new generation of applications that derive value from data they used to throw away. In this presentation Ian Downard will discuss how to build operational environments for these types of applications with the MapR Converged Data Platform and he’ll walk through an example of a next-generation application that uses Java APIs for MapR Streams, Apache Spark, Apache Hive, and MapR-DB. We’ll see how these technologies can be used to join and transform unbounded datasets to find signals and derive new data streams for a financial scenario involving real-time algorithmic trading and historical analysis using SQL. We’ll also discuss how MapR enables you to run real-time data applications with the speed, reliability, and security you need for a production environment.

Ian Downard is a technical evangelist for MapR where he is focused on creating developer-friendly ways to use the MapR Converged Data Platform.
