  2. Using ThreadExecutor and ThreadPoolExecutor in Python can help manage tasks efficiently, especially in scenarios like log aggregation.
  3. Error handling is crucial in programming, and sometimes unconventional solutions are needed to manage exceptions effectively.

You can't handle Errors

🕹 Technology Programming Error Handling
  1. Faults in code lead to errors, which then cause failures in a program's behavior. Understanding this process is crucial for effective error handling.
  2. Handling an error means returning the program to a known, correct state, which usually involves restarting it in some way. Proper failure handling is key.
  3. Exceptions as both error handling and additional return values can lead to more faults and failures. It's important to define and address failures distinctly from errors.

Daily bit(e) of C++ | Domain specific errors using std::error_code

Daily bit(e) of C++ • 78 implied HN points • 15 Jan 24
🕹 Technology Programming Error Handling
  1. To represent domain-specific error codes in C++, use std::error_code customization mechanism.
  2. The custom implementation involves an enum for error codes, an error category for text descriptions, and a mapping from enum type to category type.
  3. This customization allows for a more specialized and descriptive handling of errors in C++ programming.

Unit Testing with async/await

Jacob’s Tech Tavern • 1 HN point • 18 Jul 23
🕹 Technology Unit Testing Error Handling
  1. Unit Testing with async/await allows for writing robust and maintainable software using modern language features.
  2. Async tests focus on checking interactions with dependencies, successful function calls, and handling error states.
  3. By making code testable through dependency injection, it becomes cleaner and easier to reason about, with encapsulated logic and separated responsibilities.
