BEAM languages, such as Erlang and Elixir, offer a powerful tracing mechanism, and Erlang Doctor is built on top of it. It stores function calls and messages in an ETS table, which lowers the impact on the traced system, and enables querying and analysis of the collected traces. Being simple, always available and easy to use, it encourages you to pragmatically investigate system logic rather than guess about the reason for its behaviour. This blog post is based on a talk I presented at the FOSDEM 2024 conference. Introduction It is tough to figure out why a piece of code is failing, or how unk ..read more

gen_statem and protocols This blog post is a deep dive into some of the concepts discussed in my recent conference talk at FOSDEM. The presentation explored some basic theoretical concepts of Finite State Machines, and some special powers of Erlang’s gen_statem in the context of protocols and event-driven development, and building upon this insight, this post delves into harnessing the capabilities of the gen_statem behaviour. Let’s jump straight into it! Protocols The word protocol comes from the Greek “πρωτόκολλον”, from πρῶτος (prôtos, “first”) + κόλλα (kólla, “glue”), used in Byzantine gre ..read more

What is Elixir: Exploring its Functional Programming Essence In our latest post, we’ll be exploring Elixir, a robust programming language known for its concurrency and fault-tolerance capabilities. We’ll look at some of Elixir’s syntax, and core features, as well as the Elixir community some resources for beginners and enthusiasts alike.  The birth of Elixir As the brainchild of José Valim, Elixir is rooted in Valim’s experiences with Ruby on Rails and Erlang. Elixir aimed to tackle the challenges of building scalable and fault-tolerant applications. Harnessing the power of the Erlang Vir ..read more

In the context of transactional systems, having a single process to manage each user interaction means any issues with one process remains contained and does not affect the rest, therefore, the system keeps running smoothly. This approach prevents the unfortunate situation where a solitary user’s problem could otherwise impact the entire platform, thereby preserving user trust and system integrity amid surges in usage.  The phrase “let it crash” is very common among Elixir/Erlang developers, it’s not to disregard the significance of system crashes or errors; rather, it signifies the resil ..read more

In the realm of technology, speed isn’t merely a single factor; it’s a constant way of life.
