The better the autopilot the worse the pilot

https://julienreszka.com/blog/the-better-the-autopilot-the-worse-the-pilot/og.png
Automation doesn't make operators more careful. It makes them forget how to be. The more reliable the system, the less ready the human. The argument for automation is that it frees up cognitive bandwidth. Fewer routine decisions means more headroom to think carefully about the ones that matter. What actually happens is the opposite: when a system reliably handles a task, the human ...

Adopting the Parallel DWARF linker in dsymutil

On Apple platforms, the development experience was designed around making the compile-link-debug cycle as fast as possible. For debugging, that means that rather than processing large amounts of DWARF to link it into the final binary, the linker leaves the debug info in the object files and records a debug map that tells the debugger where to find it. When you’re debugging locally, that’s all ...
