Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ask HN: Most interesting tech you built for just yourself?
https://github.com/piqoni/matcha can summarize feed articles with gpt3.5 , but not categorize yet

Matcha - A local RSS daily digest generator (in markdown or terminal)
Ah, it's written in Go so executing the binary is even easier. No need to install anything else. I added linux-arm64 on the release notes. Let me know if you face any trouble. At the end of this https://github.com/piqoni/matcha/releases/tag/v0.5.3

RSS meets GPT-3
I added yesterday a simple OpenAI integration to Matcha RSS Reader so it can summarise RSS articles using GPT-3. I think it could be a useful feature when you just want to know the gist of something (like in a news article) or help you decide whether to click an article when the title is a bit cryptic.

RSS Readers That You Can Self Host
Check Matcha, my own open-source daily digest RSS reader: https://github.com/piqoni/matcha
"Hosting" is as easy as executing the binary file. :)
You can read the feeds in any markdown reader (such as Obsidian) or Terminal.

Show HN: A Ghidra extension that turns programs back into object files

Ask HN: Tell us about your project that's not done yet but you want feedback on
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.
