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.
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.

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…
