Jon Coens shares Facebook's experience migrating a massive codebase to Haskell and building the Haxl infrastructure for high-performance spam filtering.
Slides and more info: codemesh.io/codemesh2015/jon-coens The Haxl project is running in production at Facebook, and it's been a fascinating ride along the way. We've migrated a 100K line codebase to a completely separate language, built novel infrastructure in Haskell, launched it in a crucial system, and grew dozens of Haskell developers, all without missing a beat. Come learn what blood, sweat, and tears were needed to make this Haskell success story. Talk objectives: - The talk aims to show our experiences with using Haskell on a large project: what we needed to change in Haskell to make it run in a high-performance server and what it took to migrate between languages (both technical and human). Target audience: - Anyone curious how migrating an existing project to Haskell may look like or what Facebook's biggest foray into Haskell has been. About Jon Jon Coens is a software engineer at Facebook. After building robots at CMU's CS program, he's been building anti-spam infrastructure to keep the bad guys off Facebook. In 2013, he founded the Haxl project with Simon Marlow and has spearheaded the growth of Haskell at Facebook.Why it's here

Is Haskell still used in Facebook for Spam Filtering in 2021?
Is the system described in [video still up and running in Facebook? I want to make sure I don't provide outdated information when advocating Haskell.
There are 2 aspects to this:
1. Is Haskell still being used for Spam Filtering?
2. Is the system still using Static Rules? Or all static rules are gone and replaced with ML models?
Two friends who left Facebook at 2016 gave me contradicting information, one said it was replaced with ML written in C++, and the other said the system is still up and running. So I am asking here to see if anyone has more recent information.

…Real World Haskell next and plan to write code then, so any talk that goes beyond the basics will go over my head for now. I really enjoyed the talk on "Running Haskell at Facebook Scale", not so much because it taught me any Haskell basics but because it sold Haskell. Talks on Haskell success stories will do much for the adoption of the language

I am very excited about Haskell and can't wait for to get a good understanding of the new and exciting ideas that it offers so much that I am willing to persevere with the learning curve. But it would really help if there were more beginner-friendly talks.
PS: I've seen all of Erik Meijer's talks on channel 9.…
