Looks like #AdventOfCode 2024 is #AdventOfGraph! Today - day 6 : path finding in a maze with a twist! Like always, if you get the #GraphModeling part right, queries are easy to ✍️ and 🚀efficient! Here ➡️#Cypher with #QuantifiedPathPatterns for the win! #Neo4j Puzzle: adventofcode.com/2024/day/6 Solution: github.com/halftermeyer/A…

@HappyPunch How does one defend against that? Asking for a friend

This is WILD 🤯 Russian wrestler hit a flying squirrel down 3 points AT THE BUZZER for the win 😱

Jsuis juste meilleur que lui sur PPT mdrrrr

J'ai testé Claude ces 2 dernières semaines En théorie je perds mon job d'ici 6 mois

Announcement 🎊 GRAPH TYPE is now in Public Preview in #Neo4j 2026.02! What this means: ✓ Strict data quality - Enforce property types, mandatory fields, label implications, and relationship endpoints in one place ✓ Flexible governance - Validate your core model without sacrificing Neo4j's schema-flexibility for ad-hoc evolution ✓ Simple lifecycle management - Four commands handle everything: SET, ADD, ALTER, and DROP Read more: bit.ly/4sxoeCl

Building AI-ready systems starts with the right data foundation. Join Jesús Barrasa for a webinar and learn how domain modeling and ontology integration strengthen graph schema design by embedding meaning, context, and shared understanding directly into your knowledge graph. You’ll discover: • How domain modeling and ontologies create scalable, semantically rich data foundations • Why a formal semantic layer improves consistency, clarity, and interoperability • How #AI can accelerate modeling, enhance semantic alignment, and support schema evolution Whether you’re designing a new graph or evolving an existing one, this webinar will help you build connected data models that are truly AI-ready.

@BrianRoemmele Just put random people in this rocket to live the French 70's experience.

The first goal that you think of?

@jkoonyango @90sfootball Ballon d'Or was for European players only until 1995.

@90sfootball Where is Abedi Pele and Joel Tiehi?

Jean Pierre Papin - 1991 Ballon d'Or winner 🏆

🔍 Neo4j v2026.01 introduces #Vector search with filters as a preview feature: you can apply predicates inside the vector index at query time so the index behaves like it only contains vectors that match your criteria. Helping with: -latency low -relevant results bit.ly/4qZW5Dy

Si le destin de l'univers en dépendait... quel joueur actuel est-ce que vous choisiriez pour finir ici ?

⇥ Uini Atonio a été admis hier au Centre Hospitalier de La Rochelle suite à une suspicion de problème cardiaque. Les examens médicaux ont confirmé un accident cardiaque. Son état est aujourd’hui stable et il demeure, sous surveillance, en soins intensifs. Il est désormais établi qu’il ne pourra pas poursuivre sa carrière de joueur ▾ staderochelais.com/actualites/new…

@PerseusLeGrand “a minima” pour “au moins”. Pédant + fautif => irritant.

Quel est, selon vous, le pire tic de langage ? Celui qui vous irrite et qu'il faut bannir immédiatement.

@fuckcomputer Epic! AI money flowing straight to 127.0.0.1

claude code is fucking insane i know literally NOTHING about coding. ZERO. and i just built a fully functioning web app in minutes http://localhost:3000/ check it out

@CaminoTV Papin vs Belgique

Les gars c’est quoi le plus beau but qu’on puisse marquer sur un terrain de foot ? (Genre retourné, madjer, ciseaux etc…)

🌲 Advent of Code 2025 – Day 12 (the finale!) is live! Just shipped the last puzzle of the year… entirely in Cypher, naturally. Turned what looked like a scary 2D polyomino packing challenge into a single, almost suspiciously short Cypher query. Sometimes the hardest-looking problems have the simplest solutions when you squint at the numbers the right way.

🎄 AoC 2025 – Day 11 done in pure Cypher Part 1: build the wiring graph → count all paths you → out. Easy. Part 2: count svr → out visiting both dac and fft. Thousands of nodes, billions of paths → naive query dies. Saved by the fact the DAG has tiny vertex separators (3–5 nodes per layer). When life gives you mandatory nodes in a DAG, find the bottlenecks and multiply. Still riding the Cypher sleigh! @pierre.halftermeyer/advent-of-code-2025-day-11-reactor-073e1418a075" target="_blank" rel="nofollow noopener">medium.com/@pierre.halfte… #AdventOfCode #Neo4j #Cypher #GraphDatabases
