Show HN: Endless – An attempt to unify the social media experience
Hey guys,<p>Endless is an open-source mobile app that curates posts from your favorite websites in one place with a common interface. The application uses custom extractors specifically written for each website. This way you can endlessly scroll through posts and save the ones you like without having to deal with ads.<p>With the Endless server I am hosting you can also upvote and leave comments on posts without creating an account! With random tokens linked to your actions you basically use your device as your account and undo your actions in the future without spoiling your identity.<p>I hope to add more extractors in the future. Feel free to install the app and check out the extractors yourself or contribute to the project! I always love to hear your comments and feedback.<p>GitHub: <a href="https://github.com/kaangiray26/endless">https://github.com/kaangiray26/endless</a><p>APK Releases: <a href="https://github.com/kaangiray26/endless/releases">https://github.com/kaangiray26/endless/releases</a>

Show HN: Superblocks AI – AI coding assistant for internal apps
I’m Frank, the Head of AI Engineering at Superblocks. We’re a platform for enterprise developers to build and host mission-critical internal apps.<p>Today we launched Superblocks AI and are excited to hear feedback from the HN community!<p>Superblocks AI combines the power of the Superblocks drag-and-drop App Builder with robust AI code generation, code optimization, code explanation, mock data generation, and API call generation across SQL, Python, JavaScript, JSON and HTML.<p>We built Superblocks AI with the intention to streamline some of the repetitive and often confusing aspects of building internal tools, here’s a brief overview:<p>Generate Code: LLMs like ChatGPT have quickly become a critical part of developers' lives and we wanted to bring that experience natively into our product. The response is streamed for the best UX, similar to Chat-GPT, and can be modified before use.<p>Explain Code: Understanding someone else’s code for large internal engineering teams is often a challenge. Highlight code and Superblocks AI offers an explanation that you then have the ability to add as a comment.<p>Edit Code: You can make alterations to code by highlighting it and choosing prompts like optimize performance, enhance readability, or something custom. We've added an inline code diff view for easy verification of changes.<p>Generate API Calls: You often want to make an API call but need to spend 30 minutes looking up the documentation and crafting the correct call in Postman. We provided a way for you to give a prompt, and Superblocks AI will generate REST and GraphQL queries for APIs like Stripe, Salesforce, your favorite SaaS provider, and more.<p>Generate Mock Data: This enables faster UI development by generating mock data for components like tables, charts, grids etc., which can be especially handy during prototyping.<p>I'd love to hear feedback from the HN community on how you think this feature should evolve over the next few months!

Show HN: Clang-uml – C++ to UML diagram generator based on Clang
Hi,<p>clang-uml is an open-source C++ to UML diagram generator, driven by YAML configuration files.<p>The main idea behind the project is to easily maintain up-to-date diagrams within a code-base or document legacy code.<p>The configuration file for clang-uml defines the types and contents of each generated diagram.<p>The diagrams can be currently generated in PlantUML and JSON formats.<p>Main features:
- class, sequence, package and include diagrams
- up to C++17 with support for C++20 concepts
- visualization of template specialization relationships
- declarative diagram content filtering based on namespaces, elements and relationships
- relationship inference from C++ containers, smart pointers and custom templates
- customizable interactive links in diagrams (SVG output only)
- generation of UML packages from namespaces or directories
- JSON output containing intermediate diagram model representation for custom processing<p>More features, usage information and examples are in README at <a href="https://github.com/bkryza/clang-uml">https://github.com/bkryza/clang-uml</a> and online docs at <a href="https://clang-uml.github.io" rel="nofollow noreferrer">https://clang-uml.github.io</a><p>In particular, checkout diagrams generated from test cases here: <a href="https://clang-uml.github.io/md_docs_2test__cases.html" rel="nofollow noreferrer">https://clang-uml.github.io/md_docs_2test__cases.html</a>

Show HN: Mofi – Content-aware fill for audio to change a song to any duration
I worked on a web service that allows you to import a song and define a target length that the song will be shortened or lengthened to. It does this by analyzing the song and finding repeating audio patterns. This is helpful for making any song match a video or performance with a set duration. You can also specify areas of the song to prefer or avoid. An example is available here: <a href="https://mofi.loud.red/edit/8bd3fdf780f8c3927e41029f3b957f8a7ed96863" rel="nofollow noreferrer">https://mofi.loud.red/edit/8bd3fdf780f8c3927e41029f3b957f8a7...</a><p>The cool thing is that after the song is analyzed on the server, the client can recompute and preview the results completely client-side through an implementation that uses Web Workers and WebAssembly. The audio previewing uses Tone.js. I am thinking of writing up some more details about the implementation in the future.<p>I'm still working on a way to explain this easily, but I like the idea of carrying over the concept of content-aware fill from images to audio.<p>Please let me know if you have any comments or questions!
