Dap-mux – Connect your editor and REPL to the same debug session
I have been coding over four decades, in many languages, on many projects (including Firefox, Final Cut Pro, the Newton, and Fullwrite Professional if you can remember that far back; all these using my "dead-name"). I wrote something small and simple to scratch an itch. It's the UNIX philosophy: small "one-trick ponies", each *really* good at their one trick, then the user can hook them together to solve actual problems. I'm a CLI guy, and for almost everything, I already have this. But not for debugging. The itch I scratched was the connector that enables this philosophy for debugging. That…

all alternatives →- IWI wrote a technical history book on LispFeb 2026 · berksoft.ca · ▲252
The book page links to a blog post that explains how I got about it (and has a link to sample content), but the TL&DR is that I could not find a lot of books that were on "our" history _and_ were larded with technical details. So I set about writing one, and some five years later I'm happy to share the result. I think it's one of the few "computer history" books that has tons of code, but correct me if I'm wrong (I wrote this both to tell a story and to learn :-)). My favorite languages are Smalltalk and Lisp, but as an Emacs user, I've been using the latter for much longer and for my…
I published a book to save you from my software architecture mistakes2024 · leanpub.com · ▲100Hey HN, I just wanted to share that after five months of intense work and countless caffeine-fueled writing sessions, "Master Software Architecture: A Pragmatic Guide" is now available. Writing this book was a crazy time. I entirely focused on it, and it took exactly 753 hours of writing, editing, and image editing & resizing(!) until the premiere. Yes, the last one (images) was a killer. If you ever think about writing a book, reserve a lot of time for it unless someone else does it for you. As a result, I am handing you the nearly 400-page book. It is a guide that will help you connect all…
- IMI'm tired of sharing code using PasteBin and Slack, so I made this2025 · turbogist.dev · ▲41
Hey developers I think we're tired of copying and pasting our codes and sharing links using PasteBin, GithubGist, or Slack. What if you could share the codes without copying the link and share them right from your favorite editor? That was the motivation for creating TurboGist. Right now, it's still in the MVP stage, and I'm trying to gather feedback from developers like you. It's available as a beta in the VS Code Extension store. Can you guys check this out? It'd help me a lot. You don't need to pay any penny, 100% FREE. However, I'm working on introducing a self-hosted feature. Besides, a…

Enable Claude to interactively debug your code2025 · github.com · ▲7I participated in the Nvidia + Vercel 2 hour hackathon in SF tonight, and built something I've wanted, but hadn't tried building. I implemented an MCP Server and VS Code extension to allow Claude Desktop to place breakpoints, step through code, and execute expressions (assuming language support). So you can ask it a question that requires actually stepping through the code and now it can actually do that - check values for you, etc. It's _definitely_ not perfect. Have improvements? Please make a PR!

Talanoa▲346Hi 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…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
