Isaac de Andrade·24wThe Lost Art of Programming Offline
Programming without internet access reveals gaps in knowledge and forces reliance on local resources like man pages, system header files, and existing code. This constraint-based approach helps identify mastered domains versus weak areas, makes learning more efficient and personal, and strengthens fundamental skills by eliminating dependency on Stack Overflow, documentation sites, and AI assistants.
It's Foss·23wThe Tor Project is Now Rewritten in Rust Instead of C
Arti 1.8.0, the Rust rewrite of Tor, introduces circuit timeout improvements that replace predictable timing patterns with randomized intervals to reduce fingerprinting risks. The release includes an experimental command for migrating onion service client authorization keys from C-based Tor to Arti's keystore, plus enhancements to routing architecture and protocol implementation. The rewrite addresses memory safety vulnerabilities inherent in the original C codebase, including buffer overflows and use-after-free bugs.
Hacker News·22wsebastienros/comptime: Comptime brings meta-programming capabilities to C#, enabling compile-time code generation and evaluation.
Comptime is a .NET source generator that executes methods at compile time and serializes their results into C# code. By marking methods with the `[Comptime]` attribute, developers can shift expensive computations from runtime to build time, improving application performance. It supports primitive types, collections, method parameters with constant expressions, and generic methods. The tool uses C# interceptors to replace method calls with pre-computed values, requiring .NET 8.0+ and C# 12+. Methods must be static, classes must be partial, and return types must be immutable.
