Show HN: I made a tactical map-based WWII submarine simulator (public beta) https://bit.ly/4wMuppi

Show HN: I made a tactical map-based WWII submarine simulator (public beta) I've seen quite a few simming discussions on HN, so thought some of you might like this - I've created a map-centered, tactical submarine simulator and it's been a blast to make. I grew up playing Silent Service II on Atari ST with my dad, then got into Silent Hunter IV in the 2000s, and most recently have been loving the more recent UBoat. In each case, the part I always enjoy the most is the plotting and charting aspect - essentially beating uncertain estimates with geometry. So I decided to see how far I could get making my own sim that focused nearly entirely on that aspect. You listen on the hydrophone, estimate course and speed, identify ships through the periscope to get the mast height, use a working stadimeter for range estimates, and then try to build a good enough firing solution before getting discovered and hunted by any escorts. Things I'm particularly proud of are the working stadimeter, the dynamic music (Holst Mars stings when your torpedo is nearing a ship), and pretty intelligent destroyer logic. I've found great reference materials online and have modeled several of the gauges directly after actual submarine instruments. Tech-wise it’s a Vite/TypeScript app which enables me to offer the whole free version of the app as a browser version. The Steam page is here => https://bit.ly/3RnOge7 The landing page is here => https://bit.ly/4wGEPGR I plan on releasing a full version soonish, including a WWII campaign with progression, patrol zones, and much more on Steam (PC, Mac, Linux/Steam Deck), App Store (iPhone, iPad, Mac), and Play Store (Android). Would highly appreciate any feedback anyone has! https://bit.ly/3Pv6Iku May 18, 2026 at 04:08PM

Show HN: I reverse engineered Apple's video wallpapers https://bit.ly/4v0cMjQ

Show HN: I reverse engineered Apple's video wallpapers Ever since Apple introduced their video wallpapers I wanted to be able to put custom videos there. I decided to reverse engineer and see what I can do. I built Phosphene to sell it, but the existing competitors were polished enough that the time it would have taken to catch up wasn't going to pay off. So I'm open-sourcing it. WallpaperExtensionKit.framework is what powers macOS wallpapers. It controls what’s shows in the Settings app. It took a lot of trial and error to replicate the behavior, but the result is that your custom wallpapers appear alongside everything else. I wanted to have an “add” button there too, but I couldn’t find a way to do so, so there’s a companion app that will put your video where it needs to be. Unlike Apple's Aerials, the video keeps playing on the desktop (not just the lock screen). The renderer drives AVSampleBufferDisplayLayer directly with PTS-offset gapless looping, and pauses or downshifts based on thermal state, battery level, brightness, and window occlusion. It’s free and works well. https://bit.ly/4uYuDHQ May 21, 2026 at 12:54AM

Show HN: Spud – cross-platform remote control, optimised for gaming https://bit.ly/4djkbVz

Show HN: Spud – cross-platform remote control, optimised for gaming Over the last few weeks I've been working on Spud, an application that allows you to control a remote computer that you can see. For example, if you have a gaming PC connected to you TV, Spud lets you use a laptop as input. It's optimised for low-latency, as it's intended for gaming. There are even a few parameters you can tune in the application. I built this mainly for myself, to solve a particular problem I had, but I hope that others find it useful too! https://bit.ly/4nKgHPC May 19, 2026 at 12:38AM

Show HN: How to Kill the Dead Internet https://bit.ly/4uk2jQx

Show HN: How to Kill the Dead Internet Ok, so maybe "how to revive the internet" would be more accurate, but if you're reading this, I got your attention, right? Here's why I want you to read on: I built a free extension, D-slop, to disincentivize anyone from posting AI writing, and eventually images and video as well, on the internet. For writing, it checks known vocab and punctuation tells, as well as subtler tells related to cadence, and assigns it a score subject to an adjustable threshold. If the text fails, users have the option to flag offending text, hide it, or block the page entirely (with the option to see anyway). For media, it's admittedly fairly weak, as it relies on C2PA metadata which is stripped from all of the social media sites where it would be most helpful. (Anyone else have chronically online boomer parents continually gobbling up slop like it's real information?) I have a D-slop+ version in the works that should be able to handle the media itself, but it's going to have to make API calls to have real teeth, which means I can't offer it for free. If this extension validates the concept, I'm happy to build it for y'all. Yes, I vibe-coded it, but an ancillary bonus to the project accrued when it inspired me to cook dinner listening to Metallica's "Fight Fire with Fire," which in turn brought my 5 y/o running into the kitchen with every musical instrument in the house for an impromptu karaoke speed metal session. It's MIT license open-source, full brief at https://bit.ly/49RROvm ; This forum is full of people smarter than me, so I'm open to suggestions. https://bit.ly/4uRn71v May 18, 2026 at 02:35AM

Show HN: Serene Bach – a Go weblog engine that runs as CGI or HTTP https://bit.ly/4eSDW7K

Show HN: Serene Bach – a Go weblog engine that runs as CGI or HTTP I originally made Serene Bach in the 2000s as a weblog engine written in Perl CGI. I rebuilt it from scratch in Go as a single binary that can run either as a CGI program or as a normal HTTP server. I know CGI is generally considered legacy technology now, but I still rely on it for shared hosting. In this version, I added Markdown support, a responsive default theme, Open Graph image generation, and static output generation. It is still in beta, but the repository includes a Docker image published on GHCR, documentation, and a local quick start. I'd appreciate feedback from anyone interested in small self-hosted publishing tools, especially if you still care about shared hosting or CGI-style deployment. https://bit.ly/4dzexgV May 17, 2026 at 04:47AM

Show HN: Codiff, a local diff review tool https://bit.ly/4ucQT0L

Show HN: Codiff, a local diff review tool Nowadays I review a lot of code locally that was written by llms. I used to review my own code using git + delta. It started to feel limiting with the amount of code written by llms. When looking at a large diff on Friday I pointed an llm at diffs.com and trees.software and told it to build an app. It only took 16 minutes, is extremely fast for large diffs, beautiful and minimal. Today I polished it up and added all the features that I need. It has file filters, search, an llm walkthrough mode, and review comments that you can paste back into your llm. I will be using Codiff a lot, and can finally review the large diff from Friday that led me to build this If you like it, fork it! https://bit.ly/4wyBFoj May 17, 2026 at 06:30AM

Show HN: SwarmWright, structured multi-agent AI defined in markdowns https://bit.ly/4dnS6Lv

Show HN: SwarmWright, structured multi-agent AI defined in markdowns I had a bunch of custom AI pipelines and a growing folder of markdown files and Python scripts holding it together. Built this to give that chaos some structure. Agents are markdown files, topology is a JSON file the runtime enforces hard. The agents are still fully autonomous: they make their own decisions, but the graph they operate in isn't. You declare who can call whom upfront and the runtime holds that line. No auth yet, fine if you don't expose the port, i guess. Two Docker commands to run it. https://bit.ly/42E7NcB May 15, 2026 at 09:50PM
