A url only notepad that hosts itself
I like playing around with bookmarklets (bookmarks that are executable JavaScript) And I wanted to make a Quine (code that prints a copy of its own source code ad infinitum) So I made a bookmark-only notepad that saves a copy of its own executable and current state to a JavaScript executable bookmarklet. As you type, a link on the page updates with the source code and the internal state. You can drag this link to the bookmarks bar to “save” your work. Works cross device if you have browser sync on. No server involved!

In plain words
A self-contained notepad built as a bookmarklet that stores notes entirely within executable JavaScript code. As users type, the tool generates an updated bookmarklet containing both the application code and current notes, which can be dragged to a browser's bookmarks bar for saving. The notepad requires no server and syncs across devices through browser synchronization. Developers interested in bookmarklets and self-replicating code will find this tool notable for its quine-like approach to data persistence.

Instant HTML Preview Bookmarklet2024 · gist.github.com · ▲130Hey HN, I recently found myself needing a quick way to preview HTML and SVG code without having to copy it into an IDE, save it, and then open it in a browser. ChatGPT's new canvas feature is great for generating code, but it doesn't provide a way to preview HTML directly. To solve this, I made a small bookmarklet that allows you to instantly preview HTML from your clipboard in a new tab. Just copy your HTML, click the bookmarklet, and it will render immediately. It's a simple tool, but it’s saved me a lot of repetitive steps, and I figured it might help others too. The bookmarklet code and…

Talanoa▲341Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
