I’ve been building Velty[1] over the past year as a tool to tame my ever-growing YouTube subscriptions. It’s a web app (PWA) that lets you organize your YouTube channels and videos into folders (with sub-folders), and view all the latest videos in one chronological feed with powerful filtering/sorting.

I built it because I was frustrated with how hard it was to manage a large number of channel subscriptions using YouTube’s default interface.

This is great! It's very close to something I desperately want to exist: a way to peruse the YouTube videos' my friends are watching.

My algo often gets bad, and the best recommendations for YouTube videos come from friends' suggestions. And sometimes I just want to be recommended something totally different than what my algo would know about.

Would it be possible to add that feature?

The idea behind Velty is to let you consume your YouTube videos mainly in chronological order, without being at the mercy of the YouTube algorithm.

Sorry, I don’t plan to add that feature.

I've been working on a free, in-browser "pre" video editor. Upload your clip, use a transcript interface to cut it down to the takes and salient bits you want to keep, then export your cuts to FCP or Resolve to complete your editing. This tool saves me about 25-30% of my editing time.

Uses transformers.js & WebGPU for running transcription, so it's pretty fast. It's still a bit rough around the edges, so I'm looking for feedback.

A single address space operating system called Fusion¹ implemented in Nim. It currently has the basic building blocks for the kernel. The rest is being built incrementally as time permits. I've also taken the time to document everything I'm doing², which some people found useful.

I've been and still working on code input (https://codeinput.com). A merge conflict resolution tool that integrates with GitHub. I'm close to move from an alpha to a beta and hopefully it'll be ready to launch in a couple months time. If you dread merge conflicts, or currently have a Pull Request stuck in a conflict state, give it a try. I should re-mention it is still in an alpha state and might bug out during the process.

Late to the game here, but I'm working on Basic Memory (https://memory.basicmachines.co/docs/introduction), a knowledge management system for the Model Context Protocol (MCP).

What makes it different:

* Claude (and other MCP AIs) can both read from and write to your local markdown files

* Creates a connected network of notes that Claude can navigate between

* All data stays as markdown files on your computer

* When you chat with Claude, it automatically builds structure with simple patterns

* You can start a new chat and just say "Let's continue discussing X" without uploading files or copy/pasting

* Files are available locally, so you can edit them in and editor, like Obsidian, VS Code, etc.

I built this because I was tired of repeating myself to AI assistants and wanted my conversations to accumulate into something useful over time. It's basically a way to give Claude persistent memory while keeping your data local and be easily readable and editable my humans.

Some people are using it to maintain project context across sessions, document systems, and build topic maps without having to manually organize everything.

I'm working on MindRoot, which is a plugin-focused agent framework with a fully customizable chat UI and swappable services and commands as well as pipes, agents and personas. The goal is to be fully user-friendly while also easily expandable for programmers. And to make it easy to share tool commands and agents. Hopefully someday with a public plugin+agent+persona registry built in.

I just finished adding support for ChatGPT's new GPT4o image generator to <https://martiansoftware.com/chatkeeper> and it's working great. Testing it over the next few days and then it'll be ready for release.

This is a tool meant for heavy users of ChatGPT who want to sync their *entire* conversation history to local markdown files. If that describes you, I invite you to check it out!

Started working on a case discussion platform for students around 18 months ago. Mostly for dentistry and medicine, but it's template-based so works well for other purposes (e.g. teachers, social workers, etc.). It's going well and is being used by three universities right now.

On the way, I developed lightweight image editor and 3D model viewer components, which I've open sourced [1].

Working on my plain text cricket live cricket site[1]. Just realised after starting that getting reliable live cricket or sport data is super hard. Tried a paid provider[2] and it’s frustratingly inaccurate. Need to figure out a better way!

Also, figuring out a way to visualise manhattan chart, score worm, wagon wheels etc using plain text ascii

All kinds of personal FOSS projects I have mostly yet to release.

[1] noscrypt - portable C cryptography library for nostr [2] vnlib - C# + C libraries for server applications, eventual high performance alternative to ASP.NET. It's really just a collection of libraries that are optimized for long running server applications. [3] vncache - vnlib cache extensions and cluster cache server over web-sockets [4] cmnext - self-hosted, vnlib based, json-file CMS + podcast 2.0 server [5] simple-bookmark - kind of deprecated, vnlib based, self hosted bookmark server

My software homepage (most up-to-date) https://www.vaughnnugent.com/resources/software/modules

I know most of yall will probably want GitHub links so here [1] https://github.com/VnUgE/noscrypt [2] https://github.com/VnUgE/vnlib.core [3] https://github.com/VnUgE/VNLib.Data.Caching [4] https://github.com/VnUgE/cmnext [5] https://github.com/VnUgE/simple-bookmark
