Leveraging Elixir's hot code loading capabilities to modularize a monolithic app Jun 21 2025 My “services startup” Alzo is an Elixir monolithic app that gets deployed with 1 instance per client. In this post we will see how Elixir’s and the Erlang VM’s hot code loading capabilties help me build client-specific features while maintaining a coherent codebase and avoiding a microservices-like situation with cascading failures or complex testing situations. If you come from outside Elixir/Erla

Most RESTful APIs aren't really RESTful

news.ycombinator.com Florian Krämer 2025-08-05 14:04:36

The original paper that describes RESTful web, “Architectural Styles and the Design of Network-based Software Architectures” Roy T. Fielding (2000), introduces the Representational State Transfer (REST) architectural style as a framework for designing scalable, performant, and maintainable networked systems, particularly web services.

Graphic artists in China push back on AI and its averaging effect

theverge.com Gus Rick 2025-08-23 09:00:00

Sendi Jia, a designer running her own studio between Beijing, China, and London, England, says she mainly uses AI generators like DALL-E to make fake photos for background panels or websites when her clients don’t have access to real ones. That’s helped clients with limited budgets, but it’s also exposed just how much of the creative process AI can replace. Recently, a potential client working in a university contacted Jia about creating the logo for a new project. Then, they changed their mind.

“Don’t mock what you don't own” in 5 minutes (2022)

news.ycombinator.com Hynek Schlawack 2025-09-06 13:04:21

A common issue when writing tests for real-world software is how to deal with third-party dependencies. Let’s examine an old, but counter-intuitive principle. Once upon a time, I made a stupid joke on Twitter about the Don’t Mock What You Don’t Own testing principle: Only mock what you own, because mocking others is rude. — Yours Truly , Tweet While it didn’t get me fired, it led to me being tricked into giving a 5 minute-long talk about it.
