An options trading game to help learn about stock options: https://trading.linsomniac.com/

A good friend of mine is a retired financial planner and is always talking about different ways I could leverage options to reduce risk in my portfolio. I understand the basics, but really don't "get" them, so I thought a game might help me to understand them better.

https://github.com/shatsky/lightning-image-viewer

Tiny desktop (pre)viewer which displays image in transparent overlay without any UI, allowing to look into specific image detail with single hand move (zoom with scroll and pan with drag simultaneously like in map apps, with nothing but display borders limiting visible image surface) and toggle between file manager and image view almost instantly (close with left click anywhere/keyboard Enter).

Also finished initial rewrite in Rust just hours ago:) (originally did it in C and intentionally tried to make it initially close to preceding C codebase before going further, so many things are still managed manually)

So I'm building this: https://summaryworld.life

It gives you clean text summaries of YouTube videos. There are obviously other tools that do this, but I wanted something that is aligned with actual principles of learning and retention, not just quick TLDRs.

Also added a feature called Related Videos. It extracts the key themes from a video and recommends the top 3 related videos, essentially creating a small “knowledge web” of sorts around the topic. Similar to youtube recommendations, but you don't watch you click and read.

You can do YouTube search directly inside the product. When you click a video, it generates a summary. So you’re still browsing YouTube, but click turns a video into something you can actually consume. Personally found it better way to consume youtube, quicker for me to get through the content I want to consume than have those 10+ Youtube tabs sitting in my browser forever.

There’s also a public library feature I added where you can make your summary public. It’s kind of fun to see what other people are learning.

Still early, but iterating on it, scratching my own itch.

I have been working on chemistry arena designed to benchmark the current SoTA LLM's on drug discovery tasks. My plan was to then focus on getting this annotated to sell this data for post training of scientific reasoning models. https://github.com/deepakorani/chemistry-arena . Also trying to find a co-founder who I can work on projects and solve problems faster to be honest.

https://kavla.dev/ It's an infinite canvas that runs SQL. I've been working with data my entire career. I feel like we need to alt+tab so much. What if we just put it all on a canvas? Currently very WIP, but there's a simple titanic demo available! Built with tldraw and duckdb wasm, running on cloudflare durable objects

Wow, this seems great for doing interviews with an analyst, or just demoing data generally. Cool product!

I’m building datenba.ch, a hyper-local “digital village” for a few small communities in rural Germany (Neckartal/Odenwald-ish).

Instead of another social network, it’s a bundle of small, practical community tools under one umbrella, combining of the shelf-software with purpose-built projects of our own.

Our current areas of focus are

- help! a neighbor-to-neighbor help board (rides, errands, PC help, garden/handwork)

- hubs! for shared spaces / tool-sharing / events / social hubs

Right now I’m building the integration surface (claims, roles, provisioning), polishing onboarding, and trying to design help!/hubs! so they’re useful even with low activity.

If anyone’s done (hyper-)local community platforms: I’d love to hear what actually drove adoption and what did not work out for you.

https://azayrahmad.github.io/win98-web/ Another Web-OS remake of Windows 98 made with vanilla JavaScript. There are already a lot of Windows web remakes, especially in this age of AI. So for this passion project I intend to make it as accurate as it could ever be without having to emulate actual Windows 98. Currently it has: - Accurate recreation of Windows shell with start menu, taskbar, windowing system. - Full des…

>Internet Explorer opens websites as they were in 1998

Impeccable.
