The Aurendil team is India-bound for SIGMOD 2026 🛫 Looking forward to some good conversations with the DB research community. Who else is going?

Virtual graphs sourced from relational databases: this is what a great team and I have been working on @neo4j.com the last months. For me, it’s kind of full circle: #SQL, #Cypher and now SQL again behind the scenes. A journey way over a decade for me personally. neo4j.com/blog/graph-d...

Spring Data 2026.0.0-RC1 enters release candidate phase spring.io/blog/2026/04...

In my preparation of my talk @jcon.one about #JSpecify, I released version 4.0.0 of #Neo4j migrations, fully embracing JSpecify and #NullAway. Null-safety on the Java module path, as it should be. See you next week in Cologne. github.com/michael-simo...

Behind every release are months of obsessing over details. 🚀 While you're building with Spring 7/Boot 4, we’re sharing the "why." This @infoq.com interview covers API versioning, Jakarta EE 11, AI, tooling, and what’s next. Full story: www.infoq.com/articles/spr... #SpringFramework #SpringBoot

This Sunday I gave a talk at a conference and someone came to me afterwards telling me that my posts played a part in politicizing them. Still thinking about that. A lot of the time it feels like one is just yelling at the clouds but we can sometimes make a difference in each others' lives.

Vermutlich sagt am Ende nichts so viel über die völlig kaputten Prioritäten und Diskussionen unserer Gesellschaft wie dieser komplett absurde Affenzirkus um diesen depperten Buckelwal.

📝 "Hardwood Reaches Beta: S3, Predicate Push-Down, CLI, and More" Happy to announce Hardwood 1.0.0.Beta1, adding S3 support, predicate push-down for both local and remote files, Avro bindings, a CLI for inspecting Parquet files, a new website, and much more. 👉 www.morling.dev/blog/hardwoo...

🚀 Neo4j Migrations 3.3.1 has been released! https://github.com/michael-simons/neo4j-migrations/releases/tag/3.3.1

Released version 1.0.1 of my #Native #Image #Config transformer plugin for the #Maven #Shade plugin that also deals with types defined in reachability-metadata-schema-v1.2.0.json format: codeberg.org/michael-simo... Useful if you need to shade stuff in ur projects that comes with #GraalVM config.

May I hold up the mirror a bit more? DevRel: most report into marketing. Which means they do marketing, aka the stuff they produce is there primarily to sell more products/services. Also: DevRel mostly writes sample apps, not production-grade. All tech looks awesome when writing hello-world apps.

📈 Today, we are releasing DuckDB version 1.5.1, a patch release with bug fixes, performance improvements and support for the Lance lakehouse format. ➡️ duckdb.org/2026/03/23/a...

Think about that if you find yourself spending your times being angry online. Go outside, meet some real people with similar interests, and live your life instead of wasting it away. :)

JavaFX is back — now part of the Java Verified Portfolio. Proper support again across Java versions. Big for desktop apps. Modern Java can do way more than people think — even AI and full stack with fewer moving parts. Also: great hallway track, Brian Goetz, Stuart Marks, and Duke 🙂

Excellent read. A sufficiently detailed spec is not far from code. I wouldn't be surprised to see a formal grammar for specs emerge, at which point we'll just have invented a higher level programming language or reinvented MDA. And then we'll just need a compiler, not an LLM.

Nice post about #Neo4j and the data ecosystem. neo4j.com/blog/develop... Including #Databricks, #Snowflake and #MicrosoftFabric and why JDBC is alive and kicking.

🚀 Neo4j Migrations 3.3.0 has been released! https://github.com/michael-simons/neo4j-migrations/releases/tag/3.3.0

github.com/making/nulla... A Maven plugin that configures ErrorProne and NullAway for nullability checking. It replaces the ~40 lines of maven-compiler-plugin boilerplate typically required to set up NullAway.

🚀 Neo4j Migrations 3.2.1 has been released! https://github.com/michael-simons/neo4j-migrations/releases/tag/3.2.1

so, two cool things re: duckDB in action by @markhneedham.com, @mesirii.de, and @rotnroll666.bsky.social happened. 1. it was featured at @datadaytexas.bsky.social by @motherduck.com at their booth. 2. it was translated into japanese by impress. the book: hubs.la/Q0415RWM0

While I emptied my Twitter account a year ago and set it to locked, never logged in again, I decided to delete it today. You should do too. There is absolutely zero benefit hanging out with the filth.

Its a new year - how about coming to work on the Quarkus team ? ibmglobal.avature.net/en_US/career... location: Dublin/Ireland

Well excuuuuse meee, Robin! But, as far as save the world soundtracks goes, the Butthole Surfers would have absolutely slain! #StrangerThings

Can't wait for the loosened up, non-perfect, but quickly shipped AI-enhanced updates to hit my banking and insurance services next year. Im sure there will be no issues there at all.

Just got accepted to a Java conference in 2026. My talk will be brand new and build upon my 1BRC presentation. It will try to solve the problem by using all available Java concurrency concepts rather than tuning the code into a C-like hell.

Let's talk about AI Hype and the Theory of Constraints. From a business perspective, the key metric is "lead time." The time it takes to get an idea to the point where it's producing revenue ("in the customer's hands"). 1/10

Nice. I got accepted at @jcon.one 2026 in #Cologne in April. Hear my explaining everything you need to know about #Java and #Jspecify. Looking forward to it and thanks to @richard.fichtner.dev not minding my small rant in one of the submission text fields :D

I bet anyone under him acting like this would have to take a mandatory drug test.

📺 "Distributed Systems 6.2: Raft" Enjoyed this intro to the Raft consensus algorithm, part of a larger DistSys lecture series by @martin.kleppmann.com. The pseudo-code makes it actually digestible really well. Great watch! www.youtube.com/watch?v=uXEY...

War is peace, freedom is slavery, we only fight the CO2, not its sources. What a delusional shit show.

This is simply lovely - the agentic graph of Stranger Things. Feels like a return to form for @neo4j.com's nerd-led marketing! neo4j.com/blog/news/ho...

Join the german Spring 🍃 team 🧑‍🤝‍🧑👭👫 in Hamburg ⚓️ for a JUG evening with a series of talks. See you there! www.meetup.com/de-DE/jug-ha...

This is a nice post by @myfear.com www.the-main-thread.com/p/reactive-m... And while I am able to control my #Apple #Music locally from codeberg.org/michael-simo... I might just add something like this for fun. Thanks, Markus, well done.

If you want to use [At]Grab still in your #Groovy scripts in 2025, you need to make sure that #Apache #Ivy is configured to use #Maven #Central in a secure manner… Here's how, everything except line 12 is #Grape's default: gist.github.com/michael-simo... #Java #JVM

Dear World: Now is a good time to get off social media that’s becoming any combination of “less useful”, “less safe”, or “less fun”. I’ve been on Mastodon for 3 years and am convinced that right now, in late 2025, it’s the best place to go. Come join me. Here’s why. www.tbray.org/ongoing/When...

I have to say, semgrep.dev is quite a nice tool at first look. Much more accurate than others, way less false positives.

Due to the Liquibase license change to the FSL, I've deprecated the LiquibaseDatabase, which is used for jOOQ code generation: github.com/jOOQ/jOOQ/is... Going forward, the recommended way to integrate Liquibase with jOOQ is by using testcontainers: blog.jooq.org/using-testco...

So, I learned that as a senior developer working at #Neo4j I am basically a #Neolith. Love it.
