a compiler from Python syntax to JavaScript syntax (like CoffeeScript)

In plain words

PYXC is a compiler that converts Python syntax into JavaScript code. Launched in 2010, it allows developers familiar with Python to write code using Python's syntax while targeting JavaScript environments. The tool is designed for developers who prefer Python's readability and structure but need to deploy JavaScript applications, similar to how CoffeeScript bridges Ruby and JavaScript.

  I built a hardware processor that runs Python2025 · runpyxl.com · ▲983

  Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…

  Talanoa▲340

  Hi 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…

  I asked an HN member for feedback and she blew my mind▲453

  A few days ago, I responded to a comment by bloggergirl offering to read anyone's web copy and help. I shot off an email hoping for a paragraph or two of feedback on my startup's copy. Instead I received a professional, detailed deck of tons of invaluable well thought out feedback. It must have taken her an entire afternoon. Here's a link to it: http://www.slideshare.net/shereefb/recommendations-for-bettermeans To top it off, this isn't someone with a lot of free time on her hands, she's only days away from launching her own startup (page99test) This community blows my mind!

  Review my project: MarkUp, a tool to draw on any webpage.▲90

  Here's the website: http://markup.io/ We created MarkUp at Medium to help make the QA process better for sites we're working on. Grab the MarkUp bookmarklet, go to some page in your browser, then click it to draw on the page. Publish to make a link you can share. We've tried similar tools like BounceApp, Notable, and Skitch. Everything else we found is screenshot-based or takes us out of the browser. We wanted something that felt quicker than screenshots and more integrated with the browsing experience. Instead of taking a screenshot, MarkUp snapshots the DOM in the current page, strips the…
