Virtual Meetup - OpenRewrite: Making your source code fix itself

Hi Community,

I am happy to announce that this Thursday (the 10th of February), Jonathan Schneider will hold the discussion about “OpenRewrite: Making your source code fix itself”.

Also, remember that we changed the link to join the Meetup!

The software industrial revolution has arrived. Software is now 80% open source and third party and 20% proprietary code that stitches it together into business critical applications.

We are challenged with the ongoing maintenance of increasingly large and diversely composed codebases and ecosystems. Dependencies are changing frequently and evolve at their own pace. Not updating leads to critical bugs, performance, and security issues.

In this talk we’ll introduce OpenRewrite, an automated refactoring technology that was born at Netflix in 2016. We’ll write the code for a recipe live that fixes a known vulnerability and execute it across 100 million lines of open source code, culminating in pull requests to key open source projects. The recipe will be made available in open source for you to apply to your own codebase at the end of the session.

Jonathan is co-founder and CEO at Seattle-based Moderne which automates software maintenance activities at scale. He founded OpenRewrite at Netflix and went on to found the Micrometer project as a member of the Spring Team. Jonathan is the author of “SRE with Java Microservices” (O’Reilly). He is an Army veteran and two time bronze star recipient.

There will be tutorials, challenge talks, informal networking sessions, roundtables and ample opportunity to mix with other like-minded people from the MDE world. Also, there will be a wide range of sessions including keynote speakers: Tony Clark, Aston University; Balbir Barn, Middlesex University or Mohammadreza Mousavi, King’s College.


P.S. We get a recurring question: “Are presentations recorded?”. The answer is not, and the reasons are explained here On recording Virtual Meetups - #7 by voelter
