ELF Injector

The ELF Injector allows you to "inject" arbitrary-sized relocatable code chunks into ELF executables. The code chunks will run before the original entry point of the executable runs. Included in the project are sample chunks as well as a step-by-step tutorial on how it works. It's a mix of C and assembly and currently runs on 32-bit ARM though it's easy to port to other architectures.

ELF Injector launched on July 29, 2025 with 39 votes, #611 of 9,223 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 1 year on.

In plain words

ELF Injector is a development tool that inserts custom, relocatable code into ELF executables, executing it before the program's original entry point. Built with C and assembly, it currently targets 32-bit ARM architecture but supports porting to other platforms. The project includes sample code chunks and a tutorial demonstrating how code injection works, making it useful for developers who need to modify executable behavior or add initialization routines.

    Repo: https://github.com/valdanylchuk/xcc700 Hi Everyone! I just wrote my first compiler! - single pass, recursive descent, direct emission - generates REL ELF binaries, runnable using ESP-IDF elf_loader - very basic features only, just enough for self-hosting - treats the Xtensa CPU as a stack machine for simplicity, no register allocation / window usage - compilable on Mac, probably also Linux, can cross-compile for esp32 there - wrote for fun / cyberdeck project Sample output from esp32: xcc700.elf xcc700.c -o /d/cc.elf [ xcc700 ] BUILD COMPLETED >…

    This post introduces elfconv, a binary translator that converts Linux applications into WebAssembly. repo: https://github.com/yomaytk/elfconv Recently, performance has improved dramatically. In our LINPACK benchmark, the Wasm generated from ELF/AArch64 by elfconv now runs at roughly 60–80% of the performance of the Wasm directly compiled from source code. This shows that elfconv can produce WebAssembly with practical, real‑world performance! Furthermore, compared to QEMU running in the browser, it achieves approximately 68× the performance.

    Hi 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…

  • Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

  • Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

  • Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…

  • Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
