This Week in Neo4j: Java, MongoDB, Microservices, Graph Theory, and More

We are pleased to announce the release of the brand new Cypher Intermediate Queries course on GraphAcademy. This course is the second in the Cypher learning path, building on the knowledge gained in the Cypher Fundamentals course by teaching you how to speed up your queries using indexes and constraints. The course outlines the indexing options available in Neo4j, before providing hands-on exercises for creating each index type.

We extended the CFP deadline for NODES by a few more days! Don’t wait, submit your talk by August 31, 2022 now. Make sure to save the date for the Neo4j NODES conference on November 16 and 17, 2022.

Cheers,
Yolande Poirier

PS: Code and golf this summer!With Neo4j Code Golf challenge, you have the chance to win prizes totaling $27,000!!

GRAPH WITH NEO4J: Create a Sustainable Partnership-Based Metagenomic Supply Chain

In this GraphConnect Talk, Senior Data Engineer Saif Ur-Rehman explains how Basecamp Research uses Neo4j to draw links between the genomic and taxonomic contents of samples collected from around the world. This enables discovery of commercially valuable products for the bioeconomy that are identified through their ML pipeline and graph algorithms. Their goal is to ensure that the benefits from these products flow back to the stakeholder communities and guardians of biodiversity.

TRAINING: Graph Theory Video Series

Hello #algofam,
I made this free tool as a side project:https://t.co/0oiTiGNGz0
You just input an #Algorand account (address or #NFD) and get the graph with all the unique accounts with which you made transactions.
Here @AlgoFamily is the central account.
Hope you'll like it 🙂 pic.twitter.com/mOfdvv7tcB
