Why - I got sick of apps abusing notifications on my Android phone. While the OS does give you the ability to switch off notifications based on channels, most apps either don&#x27;t use it or abuse it intentionally. In my case, I live in a gated society that uses an app called MyGate to allow visitors, and the app intentionally pushes ads through the same channels since you cannot block them.<p>What - DoNotNotify is an app that logs all incoming notifications, and displays them grouped by app. It also captures the action behind the notification, which can be triggered from the app itself. From this log, you can create rules to whitelist&#x2F;blacklist notifications from apps depending on their notification content. These filters can even be regex expressions, which allows for more complicated use-cases. The app ships with some pre-defined rules for popular apps like Facebook, Amazon, Instagram, Netflix, TikTok, Reddit etc.<p>Where - The website is at <a href="https:&#x2F;&#x2F;donotnotify.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;donotnotify.com&#x2F;</a>.<p>Would also like to call out that the app runs purely on your device, never communicates with anything on the Internet, and only requires notifications access to work. It is completely free, and there is no advertising or hidden gotchas.

Hi HN,<p>This is a small RISC-V emulator I’ve been hacking on in Emacs Lisp as a fun weekend project.<p>It started mostly as a way to better understand the RISC-V spec by implementing things myself, and also as an excuse to write more non-trivial Emacs Lisp. It currently focuses on RV32I and related basics, and is very much not optimized or production-ready.<p>If you’re into RISC-V, emulators, or just enjoy seeing unusual things built in Emacs Lisp, feedback and comments are welcome<p>Happy hacking!

I’ve always struggled with traditional habit trackers. Filling out boxes every day feels robotic to me, and missing one day ruins the whole aesthetic.<p>So I built Voronoi just to use it myself. Instead of a rigid grid, it uses organic shapes to visualize your year. Your consistency paints a unique map associated with your time, rather than just checking off a list.<p>I&#x27;ve been using it for a while and it actually helps me stick to things, so I thought I&#x27;d share it here. I added a few other little tools and features that I personally needed along the way, but I&#x27;ll let you discover those on your own.<p>Hope you find it useful.<p>https:&#x2F;&#x2F;getvoronoi.com

Hi HN, I made OSS Sustain Guard.<p>After every high-profile OSS incident, I wonder about the packages I rely on right now. I can skim issues&#x2F;PRs and activity on GitHub, but that doesn’t scale when you have tens or hundreds of dependencies. I built this to surface sustainability signals (maintainer redundancy, activity trends, funding links, etc.) and create awareness. It’s meant to start a respectful conversation, not to judge projects. These are signals, not truth; everything is inferred from public data (internal mirrors&#x2F;private work won’t show up).<p>Quick start: pip install oss-sustain-guard export GITHUB_TOKEN=... os4g check<p>It uses GitHub GraphQL with local caching (no telemetry; token not uploaded&#x2F;stored), and supports multiple ecosystems (Python&#x2F;JS&#x2F;Rust&#x2F;Go&#x2F;Java&#x2F;etc.).<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;onukura&#x2F;oss-sustain-guard" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;onukura&#x2F;oss-sustain-guard</a><p>I’d love feedback on metric choices&#x2F;thresholds and wording that stays respectful. If you have examples where these signals break down, please share.
