The most surprising Unix programs (minnie.tuhs.org)

Article summary

The article discusses surprising Unix programs, including eqn, dc, and egrep, and their algorithms. The discussion reveals that these tools are still used today, and their functionality is still relevant. The article also touches on the topic of compiler error messages and their usefulness. The original paper is paywalled, but the comments provide insight into the content.

Main themes

• Unix programs
• compiler error messages
• algorithms
• programming languages
• error handling
• code readability
• compiler development

What commenters say

• Some Unix programs, such as eqn and egrep, are still widely used today despite being developed decades ago.
• The algorithms behind these Unix programs are surprisingly effective and efficient.
• Compiler error messages can be unhelpful and confusing, especially for beginners.
• Some compilers, like Rust, are working to improve error messages and provide more useful suggestions.
• The usefulness of error messages depends on the context and the type of error.
• Improving compiler error messages is an ongoing process that requires significant work and effort.
• Providing suggestions for common solutions to errors can make compiler error messages more useful.
• The quality of error messages can vary greatly between different compilers and programming languages.
