FastCGI: 30 years old and still the better protocol for reverse proxies

Using FastCGI as a protocol for proxy-to-backend communication can avoid HTTP's pitfalls, such as desync vulnerabilities, by providing clear message boundaries and domain separation between client and proxy headers. FastCGI is a 30-year-old protocol that is still usable today, but its lack of awareness and outdated tooling may hinder its adoption despite its potential benefits.

Consequences of passing too few register parameters to a C function

30 aragonite 2026-04-30 01:07:45 UTC devblogs.microsoft.com Llama Share 15

Passing too few parameters to a function can cause undefined behavior, memory corruption, or exceptions due to the compiler reusing memory or the processor reading uninitialized values from registers. The Itanium architecture strictly enforces this rule, raising exceptions for reading or writing outside the current stack frame.
