• Migrating from REST to GraphQL on Django & Clean Architecture with Django

    *Talk #1 - Clean Architecture with Django* On August 13, 2012 Robert C Martin released his article "Clean Architecture". Later on, it became a book with the same name and until today engineers diverge between loving and hating his concepts. This will show how to implement it with python using one of the most popular frameworks for python. Some concepts are simplified to help people to digest them better and enjoy the development process. It requires you to think a lot more about your application rather than just trust on frameworks and libraries that are out there. *Speaker Bio* Jair is a hands-on startup leader that loves to build stuff. He dedicated his career to build B2B products developing and architecting enterprise level software for the last 10 years. Currently he works as Engineer Director at Carta and manages the Enterprise Infrastructure team where he has the responsibility to lead the efforts for Carta's platform. *Talk #2 - Migrating from REST to GraphQL on Django* We'll briefly go over what REST and GraphQL are. Then we'll go into how to migrate a Django app that serves REST to one that serves GraphQL. Specifically, we'll take an existing application built using Django Rest Framework and convert it to use Graphene (https://github.com/graphql-python/graphene-django). We'll cover how to write tests, performance concerns, and areas for improvement. *Speaker Bio* Manish Sinha (https://www.linkedin.com/in/manish-sinha-9675b366/) has been active in the Django community for over five years. As Founder and Principal of North Star Labs, he has built software for numerous clients including Kleiner Perkins, Mobilize America, and The Last Mile. He has trained new engineers at UBS, TIAA, and Credit Suisse. Prior to that, he worked at Morgan Stanley in a big data group. Manish started his career as one of a handful software engineers in the White House under the Obama administration. *Lightning Talks* TBD! *Host* At ZeroCater, we believe food is one of the easiest, and most effective, ways to build culture in an office. We make it easy for companies to feed their employees delicious, family-style meals and keep exciting snack programs fully-stocked with variety and rotation. ZeroCater has successfully launched our core product, Managed Catering, into 6 local markets and are excited to be offering Snacks + Beverages to clients in San Francisco.

  • When *Not* To Use the ORM & Goodbye REST: Building GraphQL APIs with Django

    Talk #1 - Goodbye REST: Building GraphQL APIs with Django This talk will go over how to build GraphQL APIs with Django and look at the benefits / tradeoffs of using GraphQL. It will also highlight some real-world gotchas that we encountered while building the Jetpack app, and discuss what the future looks like for GraphQL + Django. Jayden is the lead engineer at Jetpack, an on-demand delivery company which helps college students get anything they need whenever they need it. Talk #2 - When *Not* To Use the ORM The Django ORM is a very powerful tool, and one of the great attractions of Django. It makes writing simple queries trivial, and does a great job of abstracting away the database layer in your application. And sometimes, you shouldn't use it. This talk is about situations and efficiencies you can obtain by using direct SQL. Even if you know no SQL at all, this can be a powerful technique to greatly improve your application's performance without sacrificing maintainability or code readability. Christophe Pettus is the chief consultant and CEO of PostgreSQL Experts, Inc., a boutique PostgreSQL consultancy based in the San Francisco Bay Area. He's also a Django contributor and a former member of the Django Software Foundation board of directors.

  • Database Design in Django & Arches: Deploying Custom Apps Without Custom Coding

    Talk 1 Database Design and Implementation in Django Just because we're not writing lots of SQL queries, that doesn't mean we shouldn't be thinking about the underlying structure of the databases in our projects. We'll explore design considerations and demonstrate how model inheritance and meta keywords can be used to deliberately structure a Django database schema. Terran Olson is a freelance software engineer whose clients have included New England non-profits, Manhattan e-com agencies, and Silicon Valley tech manufacturers. He is also a Django enthusiast who always enjoys finding new ways of using the platform. Talk 2 Arches: Platform for deploying custom apps w/o custom coding Arches is an open-source, geospatially-enabled web platform for creating, managing, and visualizing data that was inspired by the needs of the Cultural Heritage community.

  • Django ORM Predicates & Anatomy of Open edX

    Talk #1 - Django ORM Predicates Django has a flexible and easy to use system for building ORM predicates. When evaluated, these get translated into SQL queries. Unfortunately, this frequently means translating logic from django ORM into python list comprehensions, or dealing with slow database roundtrips to maintain DRY business logic. This talk explores some OSS development I did on the django-predicate library, which allows seamlessly switching between in-memory evaluation and querying the database. I'll discuss some of the oddities of how Django ORM queries are executed and discuss some worked examples of using in-memory predicate evaluation to make more flexible user interfaces and backend code here at Counsyl. Lucas's Bio: Lucas is a senior software engineer on the genomics team at Counsyl. He has been doing web development with Django for 4 years at Counsyl, and has an MS in mathematics from UIUC. Outside of Django, his interests include logic programming, software testing and formal languages. Talk #2 - Anatomy of Open edX: a modern online learning platform serving over 22 million users You may have heard of edX.org, the MOOC site created by Harvard and MIT, but did you know that the software powering this site is open source and written in Python? We’ll do a technical deep dive and explore how this software is built in a scalable way to serve millions of concurrent learners, and also show you how you can create your own Open edX site to deliver online courses at scale. Nate's Bio: Nate's first exposure to Python was in 2003 when he began using the Plone CMS, which is based on Zope. This ignited a lifelong love affair with Python. In 2004, he founded Jazkarta, a Boston-based web consultancy to build websites for organizations like Harvard, Oxfam and Smithsonian. Back when PaaS’es were sexy, he founded DjangoZoom to make it easy to get your Django apps running in the cloud. Now he's leading the 20 person distributed team at Appsembler, whose mission is to empower trainers and educators to create delightful online learning experiences. Schedule: 6:00pm - Check in and socialize. There will be food and drinks provided by Counsyl! 6:30pm - Lightning Talks (if there are any) 6:45pm - Lucas's Talk 7:15pm - Nate's Talk 8:00pm - Time to head home!
