How to write error messages that actually help users rather than frustrate them

One of the most consistently neglected parts of today’s user experiences is our handling of errors. We’re so busy designing the happy paths through our products that we often forget to give the same care and attention to the times when things will go wrong

DevEx in Action

Somewhere, right now, a software developer is pulling open a ticket from the project backlog, excited by the prospect of working on something new. As the developer begins reading through the description of the task, their laptop is suddenly flooded with alerts from the team’s production error-tracking system, disrupting the developer’s ability to focus. Eventually, returning to the task at hand, the developer studies the requirements described in the ticket. Unfortunately, the task lacks context and clarity, so the developer asks for help, which will take days to resolve.

At this point it is a liability to create new software without elixir. It’s S-tier for AI.

Rust Error Handling: thiserror, anyhow, and When to Use Each

In this blog post, we’ll explore strategies for streamlining error handling in Rust using two popular libraries: thiserror and anyhow. We’ll discuss their features, use cases, and provide insights on when to choose each library. TL;DR thiserror simplifies the implementation of custom error type, removing boilerplates anyhow consolidates errors that implement std::error::Error While thiserror provides detailed error information for specific reactions, anyhow hides internal details Return Different Error Types from Function Let’s start by creating a function decode() for illustration. The function has 3 steps:

State of exception

A state of exception (German: Ausnahmezustand) is a concept introduced in the 1920s by the German philosopher, jurist and later Nazi Party member Carl Schmitt, similar to a state of emergency (martial law) but based in the sovereign's ability to transcend the rule of law in the name of the public order and the survival of a state. Its difference to a state of emergency lies in the two concepts' diverging relationship to the law; while a state of emergency is considered to be mostly declaratory, a state of exception is considered to be more politically significant, as it nullifies the legal validity of certain legal orders by the sovereign decision.
