Show HN: SplitScreen – Create dual-video content for TikTok, YouTube, Reels
I wanted to share a side-project we’ve been working on: SplitScreen – a tool designed to simplify the creation of side-by-side videos for social media platforms like TikTok, YouTube Shorts, and Instagram Reels.<p>What is SplitScreen?<p>SplitScreen is a straightforward tool that allows you to combine two videos side-by-side in just a few clicks. We built it because we needed a simple, efficient way to create these dual-video posts without the usual hassle. It's made for content creators who want to focus on creativity without getting bogged down in technical details.<p>Key Features:<p>Effortless Merging: Combine two videos side-by-side easily, ideal for reaction videos or other dual-content formats.
Intuitive Interface: No complicated steps, just the essentials to get your videos done quickly.
Optimized Exports: Fast exports tailored for TikTok, Instagram Reels, and YouTube Shorts.
What’s Coming:<p>Custom Split Layouts: Soon, you'll have more control over the layout, with options like 60/40 and 70/30 splits.
Direct Uploads: Upload directly from your phone and export content ready for any platform.
Speed Enhancements: We’re working on making the process even faster.<p>If you’re interested, check out splitscreen.studio.<p>Looking forward to hearing your thoughts!

Show HN: FOSD – Framework of Operating System Development
The FOSD(Framework for Operating System Development) Framework is an innovative and flexible framework for operating system development. It strives to provide flexible resources and tools to help developers design, develop, and deploy operating systems efficiently and effectively. The framework is intended to support various architectures and provide corresponding build systems that facilitate the overall development of the operating system. It gives the already-implemented build system for each architecture that can automatically detect and compile user's source code and create a full operating system with proper bootloader(that's suitable with architecture.) The framework also provides HAL(Hardware Abstraction Layer) that can remedy the difficulty of having to develop all the device drivers for every hardware.
Although currently, we're in the early development stage of only having x86 architecture kernel that can barely print "Hello, world", we are planning to implement from the fundamental framework features like interrupt system or basic print system to the file system interface, complicated device drivers(corresponding to the architecture) or even feature for task management.<p>The ultimate goal is to make the operating system development easy and efficient for everybody!
Show HN: High school robotics code/CAD/design binder release
Hello HN!<p>My name is Patrick, and I am a junior at my High School’s FRC robotics team FRC 341 “Miss Daisy” (yes named after the movie). Every year, during the first weekend in January, a new robotics game is released (no it’s not battlebots). The game could be about launching balls into a goal, climbing monkeybars, or placing cubes on a see-saw. This year we were challenged to build a robot that could shoot orange foam donuts into a goal about 6 feet in the air. Here is a yt video with the game animation <a href="https://www.youtube.com/watch?v=9keeDyFxzY4&t" rel="nofollow">https://www.youtube.com/watch?v=9keeDyFxzY4&t</a>. After we received the game we then had six weeks to design, build, program, and field a robot capable of playing the game. And we did pretty well this year! I have attached a ChiefDelphi thread (robotics forum) where we have released our season materials. This being our CAD (3D model of robot), code, and design binder. I encourage you to take a look and leave any questions that you may have.<p>Thanks a lot!

Show HN: Omi – Open-source AI wearable for capturing conversations
Hi, HN! I built a proactive open-source AI necklace that transforms your conversations into summaries, proactive feedback, and insights<p>I built this because I want to use it myself: many companies are advertising such technology but no one is shipping<p>The app can work with or without wearables so you can try the experience without buying anything<p>---
Update: wasn't expecting this post to get attention, so please let me know if I need any special tags like Show HN

Show HN: VirtualStorageLibrary – .NET Tree solutions for items, dirs, symlinks
repository: <a href="https://github.com/shimodateakira/VirtualStorageLibrary">https://github.com/shimodateakira/VirtualStorageLibrary</a><p>Hello HN, I'm excited to share a project I've been working on called VirtualStorageLibrary. It's a .NET library designed to manage in-memory tree structures, including items, directories, and symbolic links.<p>VirtualStorageLibrary is a .NET library that operates entirely in-memory and provides a tree-structured collection. This library offers a foundation for managing hierarchical data structures, supporting items, directories, and symbolic links that encapsulate user-defined types <T> (generic types defined by the user). This library is not a file system. Instead, it was redesigned from scratch to create a more flexible and user-friendly tree structure. The library aims to make it intuitive to reference, traverse, and manipulate nodes by specifying paths.<p>The collections provided by .NET are linear, including types like hash sets, arrays, lists, and dictionaries, which inherently have a linear structure (such as arrays and lists). In contrast, common file systems can be viewed as tree-shaped collections, where elements are managed as nodes in a hierarchical structure. While there are existing libraries that support tree-shaped collections, I couldn’t find one that models a file system-like structure. Therefore, I conceptualized a logical interpretation of a file system and asked, "Can we implement a tree collection purely as objects?" The goal was to create a system that can flexibly manage hierarchical and allow intuitive access.<p>Key Features:<p>Flexible Tree Structure Hierarchical structure based on parent-child relationships, enabling flexible node management.<p>Various Nodes Items, directories, and symbolic links, including user-defined types <T>.<p>Intuitive Node Operations via Paths API for referencing, searching, adding, deleting, renaming, copying, and moving nodes using paths.<p>Link Management Symbolic links managed with a link dictionary, tracking changes in target paths.<p>Circular Reference Prevention Detects and prevents circular references in paths involving symbolic links by throwing an exception.<p>Flexible Node List Retrieval Retrieves node lists within directories, filtered, grouped, and sorted by specified node types and attributes.<p>Anticipated Use Cases:<p>Natural Language Processing (NLP)
Knowledge Base Systems
Game Development
Hierarchical Clustering
Education and Learning
Development Status and Future Plans:<p>The current version is 0.8.0 (prerelease). As of 2024/08, all essential features for version 1.0.0 have been implemented. However, some bug fixes, around 30 feature improvements, and refactoring tasks remain. With version 0.8.0, we aim to gather user feedback, including bug reports and feature enhancement suggestions. Simultaneously, we plan to work through the remaining tasks for version 0.9.0, targeted for release in October 2024. During this period, class names, method names, property names, and other elements in the library may change, merge, or be deprecated without notice. Detailed information will be provided in the release notes, so please check them for updates.<p>For more detailed information on the current issues and planned improvements, please visit the following page (content in Japanese):<p><a href="https://github.com/users/shimodateakira/projects/3/views/3">https://github.com/users/shimodateakira/projects/3/views/3</a><p>Thank you for your interest, and I look forward to your feedback.<p>- Akira Shimodate, AkiraNetwork

Show HN: Hacker News for film buffs
I tried to replicate the minimal design of hacker news. A small pet project I wanted to do after getting frustrated with the politics and dumb down conversations the film communities have on X/twitter, instagram and other social platforms have. I'll try to update the landing page with more links, feel free to check it out and judge.
