Working with signals in Rust - some things that signal handlers can't handle

Signals are an essential part of process life-cycle on linux, but working with them is ... fraught - probably because it's not obvious that special care is needed. In this post, we'll look at what a signal is and just one of the challenging aspects: restrictions on signal handlers.

Signals are an essential part of process lifecycle on linux, but working with them is often poorly understood - probably because it's not obvious that special care is needed. In this third post of the series, we'll look at a final aspect of what makes signals difficult to work with correctly: signal coalescence.

Signals are an essential part of process lifecycle on linux, but working with them is often poorly understood - probably because it's not obvious that special care is needed. In this second post of the series, we'll look at another aspect of what makes signals difficult to work with correctly: non-local behaviour.

How long should we expect themes and technologies in software engineering to last? In this post, we'll look at how long individual projects "last" based on data from GitHub and try to draw conclusions around what that means for choosing foundational software.
