Heaping on the Complexity

Matt Valentine-House says:

Join me on a journey through Ruby's Garbage Collector!

In this talk I'll teach you some of the details about how the Ruby interpreter manages memory. I'll introduce a project my team and I are working on that aims to make Ruby faster by improving its memory efficiency, and then we'll talk about how our implementation broke Garbage Collection.

After that we'll go on a journey together, through some weeds, and taking a few bad turns until we finally emerge with a few PR's that not only Fix GC, but make our project better too.

What does "high priority" mean? The secret to happy queues

Daniel Magliola

Like most web applications, you run important jobs in the background. And today, some of your urgent jobs are running late. Again. No matter how many changes you make to how you enqueue and run your jobs, the problem keeps happening. The good news is you're not alone. Most teams struggle with this problem, try more or less the same solutions, and have roughly the same result. In the end, it all boils down to one thing: keeping latency low. In this talk I will present a latency-focused approach to managing your queues reliably, keeping your jobs flowing and your users happy.


When the talks come to an end we'll decamp to a local pub for some food, some drinks and some chat with your fellow attendees.

Of course, even though this is the socialising part and seems more informal, please remember that still we consider it to be a part of the meeting and covered by our code of conduct.
