Show HN: Karektar – Bitmap Font Designer
Karektar is a React/TS app for building exportable bitmap fonts from custom glyph sets.<p>You can submit your own input string, and the app will generate the gallery of unique glyphs. Build your own designs using the various tools available, then export it to an OTF format when you're done.<p>This is my first front-end project, and one I picked up to learn React. I'd love to hear any feedback, especially on usability and additional features you'd like to see. Cheers!

Show HN: Get your entire ChatGPT history in Markdown files
This is just a small thing I coded to help me see my entire convo history in beautiful markdown, in Obsidian (my note-taking app).<p>[Link to Github repo](<a href="https://github.com/mohamed-chs/chatgpt-history-export-to-md">https://github.com/mohamed-chs/chatgpt-history-export-to-md</a>).<p>The Python script helps you to convert conversations extracted from ChatGPT (ZIP export all your data, sent by Openai) into neatly formatted Markdown files.<p>Also adds YAML metadata headers and includes Code interpreter (Advanced data analysis) intput / output code.<p>Feel free to fork the repo and implement your own improvements, I feel like there's alot more to be extracted from the data. Any feedback or contributions are welcome !<p>I found chrome extensions to be a bit slow and sometimes overkill for this, although I did enjoy the folder system in some of them.<p>[Link to first post](<a href="https://www.reddit.com/r/ChatGPT/comments/16k1ub5/i_made_a_simple_chatgpt_history_to_markdown/" rel="nofollow noreferrer">https://www.reddit.com/r/ChatGPT/comments/16k1ub5/i_made_a_s...</a>)

Show HN: I rewrote the 1990's LambdaMOO server
I got my start on the Internet in the very early 90s playing with, authoring in, and programming on LambdaMOO (<a href="https://en.wikipedia.org/wiki/LambdaMOO" rel="nofollow noreferrer">https://en.wikipedia.org/wiki/LambdaMOO</a>) and similar systems. Shared virtual social spaces, with a persistent object oriented authoring / scripting language. They can be classified as MUDs (depending on who you talk to) but the focus is social, creative / authoring, and shared programming not RPG gaming.<p>I've always wanted to see this kind of thing modernized and further developed. Over the last 25 years or so I've worked on similar but novel & improved things, but never finished.<p>So I decided to just re-implement LambdaMOO and use that as a base, instead and keep compatibility as a goal, but build it out on a more modern foundation that takes advantage of multiple core machines, newer network protocols, newer connectivity methods, uses MVCC transactions for the shared database etc.<p>LambdaMOO is a somewhat extensive system in that it is composed of compiler, a virtual machine, an object database, user permissions system, network runtime. In some ways it's kind of like a shared, text-based Smalltalk image/runtime... So quite a bit to implement and get right before it all works together.<p>The big challenge throughout has been slavishly maintaining backwards compatibility so existing "cores" (databases) work.<p>It's not done, but it's darn close. Would like for people who are into this kind of thing to check it out, and maybe even help.<p>Many of the technical aspects here are still provisional, but this is the start. Constructive assistance welcome.<p>(Yes, it's a rewrite in Rust, but that's not really the point, even though that's a cliche that's fun.)
