Show HN

Hacker News - Fri, 03/28/2025 - 11:55am

I made a software library for displaying piano music 7 years back, and recently ported it to the web (which is now easier than even ever).

It displays sheet music as you play, and let's you take snapshots of specific chords, then keeps a running list of chords as keyboard visuals (instead of just displaying sheet music).

Just a simple tool for songwriting/ figuring out songs by ear, or just understanding music key theory (which I'm admittedly a still a beginner at).

Show HN: Cloud IP Ranges

Hacker News - Fri, 03/28/2025 - 11:47am

Cloud IP Ranges is a website I built that collects public IP data from different cloud providers, standardises the data, and make them available to download and use.

I built this because I've been developing some products where I don't want any traffic from cloud providers (to avoid scrapping and crawling, mainly).

The service is free to use and free to use!

Hope you all find it useful.

Ask HN: What $1 can spend to make someone's life easier within a month?

Hacker News - Fri, 03/28/2025 - 11:42am

I am running a social initiative name #111challenge to find practical ways to help people with limited budgets.

I would like to challenge all the brilliant mind of HN to spend $1 within one (1) month on something that can genuinely make one (1) person's life easier.
