See you soon, Summer of Nodes 2021!

Hello everybody!

(for those of you who are wondering what Summer of Nodes is — keep reading, you can find out more below!)

We hope you had as much fun over these past weeks of Summer of Nodes as we had. We really appreciate you joining us this summer, and hope you have picked up a new trick or two along the way :) Thank you for your brilliant answers; we really enjoyed seeing what you came up with, and were humbled by the positive feedback received. We were impressed with how many of you stayed with us from start to finish, having a go at all of the challenges.

Reliving the spirit of Summer of Nodes 2020

The goal of Summer of Nodes was to provide a month of fun challenges, accessible to the complete beginner through to the experienced Neo4j practitioner. Regardless of your level, the goal was for you to walk away with some new skills, or try your hand at something you’ve not looked at before.

Perhaps you missed the event? Or maybe you just want to revisit the event, at your own pace, at leisure. Either way, here’s a reminder of those challenges.

The barbecue

Week one was all about learning about modelling, focussing on barbecues around the world. For the more experienced graphistas, we challenged you to use your Neo4j toolkit to come up with queries that would help you plan for a socially-distanced seating plan.

The online day out

Week two used the superb collections dataset from The Metropolitan Museum of Art in New York. We invited you to explore paintings by setting up and using Neo4j Bloom. For the more experienced, your mission was to plan for a virtual museum visit, by identifying which paintings met the criteria of your friends requirements.

Whodunit?

Week three was based on the excellent Knight Labs ‘Murder mystery in SQL City’. Your mission was to identify the murder and accomplice using your strengthening Cypher skills. The experienced were set the challenge to use Graph Data Science to identify other potential witnesses with connections to these culprits.

Exploring the area

Week four found us exploring Central Park in New York City. With your continuing growing Cypher knowledge, we introduced you to the spatial functionality, where you explored different points of interest within the park, as well as how far apart they were. The experienced graphistas were set the ‘fountain flight’ challenge — what was the distance of the most efficient route through to park to visit every fountain, utilising APOC and Graph Data Science.

All the relevant links to data, the live streams and other resources are in the blog posts above. For those of you who’d prefer a stream binge, check out the Summer of Nodes playlist.

We need YOU!

Did you hear about the event? Perhaps you took part? Were you an sofa supervisor? Or maybe you were chipping in with the chat? Regardless of whether you submitted an answer or not, we’d love to hear your feedback:

  • What went well?
  • What didn’t go so well?
  • What would you like to see next year?

Please let us know your thoughts, we really appreciate it!

Thank you for taking part, and see you in next year’s Summer of Nodes!
