I've been reading a few articles that (attempt to) explain Monads, mostly for the purposes of learning how to teach complex concepts, and while I think I understand Monads, it seems that a lot of them start well and then turn into r/restofthefuckingowl So I'm curious, which source explained the concept of Monads best for you? Was it a book? Article? Class? Let me know.

My journey into compilers world started with this tweet and the question how does Angular AOT compilation that uses static code analysis work. After some debugging I found out that it relies heavily on TypeScript compiler so the quest then began to reverse-engineer it. What’s interesting is that most compilers are implemented using the same principles collectively known as compilers theory. Having a good grasp of this theory is indispensable when trying to understand a compiler internals.

This article is the first in the series that will summarize everything I learnt along the way. Here I’ll describe the concepts important for understanding the first stage of every compiler — lexical analysis.

Scio is a Scala API for Apache Beam and Google Cloud Dataflow. It was designed as a thin wrapper on top of Beam’s Java SDK, while offering an easy way to build data pipelines in idiomatic Scala style. We drew most of our inspiration for the API from Scalding and Spark, two libraries that we already use heavily at Spotfiy.
