Since the earliest days of Unix, two of the core process-oriented system calls have been fork() [...]
Forking is Cool, or: A Unix Shell in Zig, or: Dave Learns How to Fork - ratfactor
In this article, I make a real, working interactive shell written in Zig. Though essentially a toy, it demonstrates the incredible elegance of the fork() system call and is an example of what can be done with absolutely no runtime memory allocations.
Thorsten Ball - Why threads can't fork
There is an interesting thread on the Go issue tracker about daemonizing processes. Most of the thread is not about daemonizing processes though, but more about why Go has no Fork() function which you can call directly in your code. The first time I read through it I was wondering and saying to myself: “Yeah, why is there no Fork()? It surely can’t be that hard to implement.” After all you can already call system calls with the syscall package. As I read more and more I realized that the problem is not implementing Fork() per se, but rather implementing Fork() to work safely in a multi-threaded environment, which most Go programs are. So I tried to find out why.

No Fork Required - Scott's Thoughts
What if another operating system isn't the solution to anything at all? What if device-level identity could tie into existing systems to help pull users out of walled gardens, rather than creating new gardens?

Segfaults are our friends and teachers
This afternoon, I got a segmentation fault in a Rust program, and was confused. This is Rust, I shouldn’t get segfaults! I quickly checked the couple of places I used unsafe, and they were either calling C functions (and checking the errors), or telling the compiler not to initialize some memory because I was going to write into it unconditionally before reading from it.

What I Found Interesting in Claude Code's Source
A breakdown of the most interesting engineering patterns in Claude Code's leaked source code: composable system prompts, runtime instruction injection, context compression, forking, prompt caching architecture, and more.
Speculative Programmatic Tool Calling
Speculative programmatic tool calling is a class of techniques for overlapping tool call computation with the code being generated by a harness.
We figured out how to exit Tiles CLI properly and wrote a deep technical dive into standard streams, pipes, Unix processes, how system signals behave with parent processes, blocking UI I/O, and how async Rust helped fix it: tiles.run/blog/controlling-ctrl-c
