[API/SDK] Show HN: I built a single API to post on all social platforms Building integrations for TikTok, X, Facebook, Instagram, YouTube, and LinkedIn got frustrating with how different every platform is with auth setup, rate limits, and media requirements. So we built Post for Me: one REST API that handles scheduling and publishing posts for TikTok, Facebook, Instagram, X, YouTube, LinkedIn, Pinterest, Bluesky, and Threads.<p>It&#x27;s built for developers. You bring your own app credentials from the social platform, so you&#x27;re in control of your data. There&#x27;s no limitations on account connections, and pricing is based on usage (not some arbitrary limitations). We wanted the API we wish we had when we first started.<p>What it does - A single POST replaces a dozen different calls - Pay-per-post metered pricing (volume discounts) and a free tier (no seat fees) - Cascading configs: set captions&#x2F;media globally, then override per platform or account<p>Try it at <a href="https:&#x2F;&#x2F;www.postform.dev" rel="nofollow">https:&#x2F;&#x2F;www.postform.dev</a>. Would love feedback, bug reports, or architecture questions!

[Other] Show HN: Gore – A Doom Engine Port in Go Hi HN,<p>I’ve been working on Gore – a port of the classic Doom engine written in pure Go, based on a ccgo C-to-Go translation of Doom Generic. It loads original WAD files, uses a software renderer (no SDL or CGO, or Go dependencies outside the standard library). Still has a bit of unsafe code that I&#x27;m trying to get rid of, and various other caveats.<p>In the examples is a terminal-based renderer, which is entertaining, even though it&#x27;s very hard to play with terminal-style input&#x2F;output.<p>The goal is a clean, cross-platform, Go-native take on the Doom engine – fun to hack on, easy to read, and portable.<p>Code and instructions are at <a href="https:&#x2F;&#x2F;github.com&#x2F;AndreRenaud&#x2F;Gore">https:&#x2F;&#x2F;github.com&#x2F;AndreRenaud&#x2F;Gore</a><p>Would love feedback or thoughts.

[Other] Show HN: Doc81 – tech documentation tool designed in AI-native mind Hello HN!<p>As a EM, I recently asked for a &quot;good&quot; handoff doc to my engineers who&#x27;re leaving, but without proper structure, the first draft was pretty crappy. Studying and thinking hard about what readers(i.e., me) might want on header level and what would be a good representation in each section, we came up with a good template for handoff doc. The result was fantastic. I think we all can write better with a proper format and template. That is where I came up with this idea, doc81.<p>Have fun, and let me know what you think!

[Other] Show HN: Unlearning Comparator, a visual tool to compare machine unlearning I built Unlearning Comparator, a visual analytics toolkit to help researchers and developers compare how different machine unlearning methods work. It provides a unified workflow to test for accuracy, efficiency, and privacy. You can check out the live demo linked in the post, and the source code is on GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;gnueaj&#x2F;Machine-Unlearning-Comparator">https:&#x2F;&#x2F;github.com&#x2F;gnueaj&#x2F;Machine-Unlearning-Comparator</a> Our accompanying paper is currently under review at IEEE TVCG. Happy to answer any questions and would love to hear your feedback!

[Other] Show HN: Interactive pinout for the Raspberry Pi Pico 2 I&#x27;ve been trying to make accessible and beautiful GPIO pinouts since I started one for the Raspberry Pi in 2013 [1]. I&#x27;ve since given the Raspberry Pi Pico [2] and Pico 2 [3] microcontrollers the same treatment when they launched.<p>Recently I&#x27;ve updated these with a new &quot;Upside-down&quot; view to complement the rear view, giving a pinout in the right orientation to match your project.<p>The Pico sites are all hand-coded single HTML pages with supporting CSS and minimal JS. They are set up to optionally install as a &quot;Desktop&quot; web app. They also degrade into a somewhat usable table in lieu of CSS and use vector graphics (for the board itself) to be viewable and printable at any size.<p>Finally, hidden behind &quot;Advanced&quot; is a pinout of the test pads and special function pins!<p>[1] - <a href="https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20130505194305&#x2F;pi.gadgetoid.com&#x2F;pinout" rel="nofollow">https:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20130505194305&#x2F;pi.gadgetoid.com&#x2F;...</a> [2] - <a href="https:&#x2F;&#x2F;pico.pinout.xyz" rel="nofollow">https:&#x2F;&#x2F;pico.pinout.xyz</a> [3] - <a href="https:&#x2F;&#x2F;pico2.pinout.xyz" rel="nofollow">https:&#x2F;&#x2F;pico2.pinout.xyz</a>

[Other] Show HN: Integrated System for Enhancing VIC Output ISEVIC stands for Integrated System for Enhancing VIC output and is a cartridge for the C64 that uses the Tang Nano 20K FPGA to monitor the bus and recreate the C64 video for HDMI output. While a tremendous effort has gone into handling all the clever C64 tricks, this should be considered a 1.0 release as there are still some demos and games that exhibit bugs. Everything needed to build one is on the github page.

[Other] Show HN: NYC Subway Simulator and Route Designer Hello HN!<p>As a long term NYC resident, I have read countless articles on ideas tweaking subway services, but always found them hard to follow without visual aid. So over the long weekend I decided to build one. It has all the basic features: trains would spawn at their origin, stop at stations, and slow down if it gets too close to another. You can also design custom routes by piecing tracks together.<p>Have fun, and let me know what you think!
