🏆 Featured talks of the week

Here are the must-watch talks uploaded since the last TTW issue.

1. 🥇 "Complexity is the Gotcha of Event-driven Architecture • David Boyne • GOTO 2024" ⸱ +1k views ⸱ 02 Dec 2024 ⸱ 00h 44m 15s

   This talk dives into the complexity of event-driven architectures. While EDA is praised for benefits like fault tolerance and decoupling, they come with hidden complexity that can grow over time if not managed well. The speaker offers three practical guardrails to help handle these complexities.

2. 🥈 "Theo Browne - Out Of Order Streaming (The Secret Powering Modern React), React Summit US 2024" ⸱ +600 views ⸱ 29 Nov 2024 ⸱ 00h 18m 30s

   The talk explores streaming in web applications. It begins by showcasing a common React app setup, where fetching and rendering data happen sequentially which leads to delays. It then presents the the solution: streaming HTML, where partial content is sent to the browser immediately allowing it to render incrementally while the rest loads.

3. 🥉"Let's write a Toy Language from Scratch in Elixir - Lucas Sifoni | ElixirConf EU 2024" ⸱ +400 views ⸱ 28 Nov 2024 ⸱ 00h 28m 17s

   The speaker introduces us to programming languages theory and outlines five key steps in creating the language: tokenizing input, constructing an abstract syntax tree (AST), printing the program back from the tree, applying syntax rewrites, and finally evaluating the tree to produce the output. The talk covers how the tokenizer converts text into tokens, how the parser validates the program structure by building an AST, and explores how these elements work together to form a simple interpreter.
