A clear, practical guide to code review: why it matters, the PERFECT principles, and how to build an effective review process.

When upgrading to Elixir 1.19 with Erlang/OTP 28, the deployment failed with a cryptic error: The fix was simple - just add one characters: But why...

I find myself writing yet another toy parser, as one does during a Christmas break. It roughly follows Resilient LL Parsing Tutorial. Not because I need resilience, but mostly because I find producing a syntax tree and a collection of diagnostics a more natural fit for the problem than bailing out on the first error.

So there I was, implementing a one element ring buffer. Which, I'm sure you'll agree, is a perfectly reasonable data structure.

Skipping expensive per-row subqueries to speed up my average query ~17%.

Running a private registry is easy; making it searchable isn't. Here's how reg taps SQLite to expose fast queries without touching S3.

This defines sweet-expressions (t-expressions) for Scheme, building on neoteric-expressions (n-expressions) and curly-infix-expressions (c-expressions). This defines an approach to making Scheme more 'readable' by adding syntactically-meaningful indentation, as well as supporting infix and functions whose names precede the opening parenthesis.

In this episode we'll learn how we can use feature flags to toggle different features of an application to different users. To do this we'll be using the FunWithFlags package in an existing Elixir application.

A guide for Elixir developers (and why you might want to)

This short tutorial explains how to use Feature Flags in Elixir. It covers a simple use case of toggling an e-mail notification in Flagsmith.

This document discusses flow-based programming with Elixir. It begins with an introduction to the speaker and overview of topics to be covered. It then covers conventional programming versus flow-based programming, using the "telegram problem" as an example. The document discusses using Elixir's new GenStage feature to implement the telegram problem in a flow-based manner, with independent, asynchronous components communicating via message passing. It also discusses how GenStage dispatchers allow for data routing and partitioning in flow-based applications. - Download as a PDF, PPTX or view online for free
