Interesting idea ("manages development processes running on ports 2000-6000"), and props for hitting the front page though technically this is a "Show HN". Screenshot(s)?
lexokoh•4h ago
Not sure I can add images here, but if you check the repo, I'll be adding one shortly.
nbbaier•3h ago
Neat! There's also a raycast extension for this kind of thing for anyone who wants to go that route:

What is "development process" ??? What is "business use case" of this tool? Such a big readme and no introduction to why I should be interested in this tool.
motorest•3h ago
> Such a big readme and no introduction to why I should be interested in this tool.

This.

Why in the hell would anyone want to kill random processes that open a port in the tange 2000-6000? And why is this need so pressing as to require a full blown monitor integrated in a task bar?

Without context, this sounds like a complete random silly project that makes no sense and serves no purpose at all.

bigyabai•2h ago
Without context, it sounds like something someone vibe-coded and git push-ed up to the internet. Which is fine, but it's just unusually precise and verbose for something that would end up being a shell alias for most developers.
todotask2•2h ago
The author also posted it on Reddit. He used it for himself, but some people use it even though it’s bad practice.
lexokoh•2h ago
It's just a tool I built for myself. There's no business case. It just helps me
hit8run•2m ago
Which is perfectly fine and a fun thing to do. I personally use the terminal but such a little monitoring tool can be quite fun and we should embrace the fun in doing things more. People over here are so soaked up by the Open Source as a business model VC-Pitch that they can't believe it when someone builds a little hobby tool with no business plan for a multi billion dollar exit. You're doing it right buddy. Don't let these Crypto-SaaS-AI-Bros ruin the fun for you.

I'm not looking forward to the near future where it will become harder and harder to distinguish little projects like this from AI generated tools.
userbinator•2h ago
The README already has a rather repugnant LLM-ish feel to it; lots of lists and verboseness, while saying very little.

Also, this is a perplexing choice (which also serves to illustrate the above point regarding verboseness):

    White background with red center: 1-9 processes (some development servers) 
    White background with orange center: 10+ processes (many development servers)
lexokoh•2h ago
A lot of ReadMe's are generated with AI. Doesn't really mean anything.
userbinator•2h ago
You're right. A lot of words that don't really mean anything; and that's exactly why you should not do it if you want actual humans to read it.

AbuAssar•2h ago
the ascii tree in "Project Structure" is a dead giveaway that AI is used in this project
pacifika•2h ago
Why would you need to do that?
userbinator•2h ago
To filter out the spam.
faangguyindia•3h ago
On macOS i've this in my zshrc file:

`killport() { kill -9 $(lsof -t -i :$1 -sTCP:LISTEN) }`

i use it like killport 8000

lexokoh•2h ago
Nice. I have this too. I wanted something more visual and expansive.
porridgeraisin•11m ago
Yeah, I have a function `whoseport` which is just your subcommand. I usually manually type kill or whatever I want with `$(whoseport 3000)`
incanus77•2h ago
These would be good additions to SwiftBar/BitBar.
hbbio•2h ago
Didn't expect to see the FSL for that kind of project :)

The part I'm interested in is the tray_icon crate but I'll look at the package directly https://docs.rs/tray-icon/latest/tray_icon/.

Ports 2000 - 6000?

I know I am getting old but when did we stop running things on 8xxx? The more 8's the more dev it was. 8000, 8080, 8088, 8888
