Threadprocs – executables sharing one address space (0-copy pointers)
This project launches multiple independent programs into a single shared virtual address space, while still behaving like separate processes (independent binaries, globals, and lifetimes). When threadprocs share their address space, pointers are valid across them with no code changes for well-behaved Linux binaries. Unlike threads, each threadproc is a standalone and semi-isolated process. Unlike dlopen-based plugin systems, threadprocs run traditional executables with a `main()` function. Unlike POSIX processes, pointers remain valid across threadprocs because they share the same address…

In plain words
Threadprocs launches multiple independent programs into a single shared virtual address space on Linux, allowing them to behave as separate processes while sharing memory. Unlike traditional threads, each threadproc remains standalone with independent binaries and lifetimes. Unlike separate processes, pointers are valid across threadprocs without code changes, enabling direct access to pointer-based data structures like strings and maps. This bridges the gap between thread-based and multi-process architectures for developers needing isolated execution with shared memory efficiency.

Experimental thread-like processes, multiple executables in one address space - jer-irl/threadprocs
This repository contains experimental code for thread-like processes, or multiple programs running in a shared address space . Each threadproc behaves like a process with its own executable, globals, libc instance, etc, but pointers are valid across threadprocs. This blends the Posix process model with the Posix multi-threading programming model, and enables things like zero-copy access to pointer-based data structures. See tproc-actors for one possible application framework building on top of threadprocs. The code for the demoed programs is at example/sharedstr/allocstr.cpp and example/sharedstr/printstr.cpp , and neither contains any magic ( /proc/[pid]/mem , etc), nor awareness of the…from github.com

Sub-millisecond VM sandboxes using CoW memory forkingMar 2026 · github.com · ▲311I wanted to see how fast an isolated code sandbox could start if I never had to boot a fresh VM. So instead of launching a new microVM per execution, I boot Firecracker once with Python and numpy already loaded, then snapshot the full VM state. Every execution after that creates a new KVM VM backed by a `MAP_PRIVATE` mapping of the snapshot memory, so Linux gives me copy-on-write pages automatically. That means each sandbox starts from an already-running Python process inside a real VM, runs the code, and exits. These are real KVM VMs, not containers: separate guest kernel, separate guest…
Forkrun – NUMA-aware shell parallelizer (50×–400× faster than parallel)Mar 2026 · github.com · ▲151forkrun is the culmination of a 10-year-long journey focused on "how to make shell parallelization fast". What started as a standard "fork jobs in a loop" has turned into a lock-free, CAS-retry-loop-free, SIMD-accelerated, self-tuning, NUMA aware shell-based stream parallelization engine that is (mostly) a drop-in replacement for xargs -P and GNU parallel. On my 14-core/28-thread i9-7940x, forkrun achieves: * 200,000+ batch dispatches/sec (vs ~500 for GNU Parallel) * ~95–99% CPU utilization across all 28 logical cores, even when the workload is non-existant (bash no-ops / `:`)…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
