ghidra VS exhibitor

I've been working on a specific reverse-engineering technique called _unlinking_ [1] on-and-off for the past 16 months or so. I'm on my third prototype (first a set of Ghidra scripts written in Jython [2], then a fork of Ghidra [3] and now a Ghidra extension [4]) and I've started a blog in order to document it [5], which side-tracked into writing a whole series of articles on reverse-engineering to introduce the topic.

What for, you may ask? Basically I'm trying to decompile a PlayStation 1 video game and I've quickly decided that dealing alone with multiple +500 KiB executables of complete utter spaghetti code wasn't going to work. Instead, I've decided that I'd rather divide-and-conquer the problem, so I've been tooling up to split executables into relocatable object files, in order to decompile those one at a time and _Ship of Theseus_-style my way to success.

Ironically, all of that stuff is so not done that I don't even know what meaningful feedback there could be. My prototypes do work, but only for 32 bit little endian statically-linked MIPS executables. The articles on my blog are draft-quality. As for the decompilation project itself that started all of this, it hasn't seen much progress due to all of those side-quests. The overall topic is so esoteric that so far I've only managed to hear about one group of two persons that tried to do anything remotely similar and one another anecdotal account [6] that this particular skill is very uncommon among reverse engineers.

Personally, I'm starting to think that maybe I could've actually reverse-engineered and decompiled the game in the time I took to get here. I've also tried to engage with Ghidra to upstream the foundations of my modifications in my fork, but after some back-and-forth it became clear that my prototype-grade stuff wasn't industrial-grade and couldn't be merged in its current state, which is why I'm currently reworking the code in my fork as a Ghidra extension.

To those that want to provide feedback after reading all of this: beware, I've had a lot of fun going down that rabbit hole, but this is one hell of a time sink _and_ a particularly tricky mind-bender.

[1] I don't actually _know_ what's the actual name for this technique, given that there are so few resources on it out there. I do know I didn't invent it.

TL;DR: A React front-end component workshop, a simple version of Storybook.

So around 5 months ago, I needed a tool to preview front-end (React) components whilst I create them for a personal project of mine. There were two options: Storybook or Ladle.

Storybook is the tool everybody knows. I've used it before quite a lot. It's very big, full-fat, supports loads of use-cases, etc.

Ladle comes out of Uber. It's very small, lean, and doesn't support that much. After trying it out for a while, it just gives me a feeling like it's a 20% project to learn some new tech.

So I realised that I wanted something kind of in the middle. Something that's a bit more customizable than Ladle, but something much simpler and less intrusive than Storybook.

This led me to create Exhibitor (https://github.com/samhuk/exhibitor) (https://demo.exhibitor.dev).

I worked on it on-and-off for a couple months, and it ended up being something that I'm quite proud of. It's not perfect, and supports only a fraction of what Storybook does, however for a tool made by 1 engineer vs the 20+ for Storybook, I'm quite happy about it!

Exhibitor, a snappy & delightful React component workshop, is GA. My aim is for Exhibitor to be an extremely fast, easy to use, and delightful tool for creating front-end component libraries.

It's been around 2 months since my last mention and quite a tonne has changed.

Looks interesting. Coincidentally, I've just completed the bulk of work on a distributed Websocket network system to synchronize certain bits of state between multiple clients for my own kind of Storybook tool [0]. How interesting!

This kind of tool is exactly what I would have needed, instead of the approach I've taken which is a bit kludgy, grass-roots, novice-like, etc.

Good work :)

I was a bit deflated when my submission about https://github.com/samhuk/exhibitor fell through the HN floor-boards.

Think Storybook but simpler, faster, better Typescript support, and uses esbuild by default.

...Is the aim. I'm the sole lead dev working on it at the moment up against the ~10-20 strong team who built most of Storybook, so it's a long road ahead, but it's growing into something I'm quite proud of and happy about.
