  I’ve been impressed with Claude Code but one thing that sometimes gets in the way in my workflows is the messy, mangled text that is shown when pasting text from the Claude Code terminal sessions. So I built an open-source utility that cleans extraneous white space, pipes, and other characters from your CC/Codex pastes. For example, you can turn this: `How can I create a Claude Code script that │ │ cleans up extraneous characters and cleans up │ │ extra spaces, new lines, and other messiness │ when I copy from Claude Code terminal │ │ prompts or copy code from Claude Responses in │ │…

  Wetlands – a lightweight Python library for managing Conda environments2025 · arthursw.github.io · ▲30

  When building a plugin system for an application, avoiding dependency conflicts is critical. To address this, I created Wetlands – a lightweight Conda environment manager. Wetlands not only simplifies the creation of isolated Conda environments with specific dependencies, but also allows you to run arbitrary Python code within those environments and retrieve the results. It uses the multiprocessing.connection and pickle modules for inter-process communication. Additionally, one can easily use shared memory between the environments, making data exchange more efficient. Docs:…

  Mac Cleanup GoJan 2026 · github.com · ▲100

  Instead of a traditional command-style CLI, it runs as a TUI in the terminal, allowing users to inspect cleanup targets before proceeding. On my macOS machines, caches and app data often take up more than 40% of disk usage. Manually cleaning them each time felt tedious, so I built this tool to make the process easier. While similar tools exist, I found it hard to quickly understand how items were categorized or how important each cleanup target was, so I built my own. Repository: https://github.com/2ykwang/mac-cleanup-go Feedback is welcome.

  Talanoa▲346

  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…

  Tetris in a PDF▲1,289

  I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

  I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!
