Show HN: A simulator for engineers transitioning from IC to management
Hi HN,<p>I’m a former C++ dev turned Product Manager.<p>I’ve noticed many engineers struggle with the "politics" side of things when they become Leads. To help with this, I’m building a text-based simulator.<p>It is NOT an AI chatbot. It is a hand-crafted, branching narrative (logic tree) based on real experiences.<p>I just launched the first scenario: "The Backchannel VP."<p>The Setup: Your VP Engineering is bypassing you and giving tasks directly to your juniors, causing chaos.<p>Your Goal: Stop the backchanneling without getting fired.<p>It’s a short, specific puzzle. I’d love to know if you think the "Correct" path I designed matches your real-world experience, or if I’m off base.<p>Link: <a href="https://apmcommunication.com/scenario/backchannel-vp" rel="nofollow">https://apmcommunication.com/scenario/backchannel-vp</a>

Show HN: DoNotNotify – Log and intelligently block notifications on Android
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'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/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://donotnotify.com/" rel="nofollow">https://donotnotify.com/</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.

Show HN: Offline tiles and routing and geocoding in one Docker Compose stack
Hi HN,<p>I’m building Corviont, a self-hosted offline maps appliance (tiles + routing + search) for edge/on-prem devices.<p>Hosted demo (no install): <a href="https://demo.corviont.com/" rel="nofollow">https://demo.corviont.com/</a><p>Self-host (Docker Compose repo): <a href="https://github.com/corviont/monaco-demo" rel="nofollow">https://github.com/corviont/monaco-demo</a><p>Docs: <a href="https://www.corviont.com/docs" rel="nofollow">https://www.corviont.com/docs</a><p>What’s inside:<p><pre><code> - Vector tiles served locally (PMTiles)
- Routing served locally (Valhalla)
- Offline geocoding/search + reverse (SQLite Nominatim-based index)
- MapLibre UI wired to the local endpoints
</code></pre>
After the initial image + data pulls, it runs fully offline (no external map/routing/geocoding API calls).<p>Next (if people need it): a signed on-device updater for regional datasets (verify → atomic swap → reload).<p>I’d love feedback: where offline maps/routing/search matters for you, and what constraints bite (hardware, fleet size, update windows, regions, deployment style).

Show HN: I used AI to recreate a $4000 piece of audio hardware as a plugin
Hi Hacker News,<p>This is definitely out of my comfort zone. I've never programmed DSP before. But I was able to use Claude code and have it help me build this using CMajor.<p>I just wanted to show you guys because I'm super proud of it. It's a 100% faithful recreation based off of the schematics, patents, and ROMs that were found online.<p>So please watch the video and tell me what you think<p><a href="https://youtu.be/auOlZXI1VxA" rel="nofollow">https://youtu.be/auOlZXI1VxA</a><p>The reason why I think this is relevant is because I've been a programmer for 25 years and AI scares the shit out of me.<p>I'm not a programmer anymore. I'm something else now. I don't know what it is but it's multi-disciplinary, and it doesn't involve writing code myself--for better or worse!<p>Thanks!
