24 alternatives to 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…

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…

Hey 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…

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…

I 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!

So, I've never written a line of Rust in my life. I wouldn't know an `&mut this` from a mutandis. But I saw a tweet about a month ago that said, in this new era of AI, you'd be able to just take a library that you love, throw a TUI around it, and call it an app. So I spent about 200 bucks last month, here's what I came up with: Imbolc is a DAW that runs entirely in your terminal. It talks to scsynth over OSC and ships 58 instruments and 39 effects. VSTs are a work in progress, also GarageBand loops if you want to recreate "Umbrella". The codebase is about 60k? lines of Rust across 5 crates,…

I recently encountered a situation where JetBrains IDEs weren't working for a project, and I wasn't even sure I wanted to keep paying the yearly fee. I decided to de-IDE myself and as part of it I decided to look at my options. The more I saw of Emacs the more interested I got. However using the Doom emacs distribution kind of threw me in the deep end without actually understanding how Emacs operates. I was lost and bounced off quick. I decided to take the approach of starting with vanilla Emacs and trying to get it to work for me as an IDE one step at a time. This post was me documenting…

Hi HN, I'm thrilled to share with you think, a command-line tool that I developed while diving back into the programming scene. For the past few years, my focus had shifted from hands-on programming to managerial roles, my last one being at Affirm (I started Affirm's Polish office). However, I recently left my job to revisit my passion for coding and see if I could still write code that works. Not to mention that with what is currently going on in AI if you are a developer this probably the best possible time for a sabbatical in human history :) My first attempt was with LangChain, but I…

Hello HN community ! Finally I have a "Show HN" post. I'm bootstrapping my first Mac app, it's a standalone Xdebug PHP debugger. It aims to help any PHP developers out there who don't want to use IDE to debug code. My app it's slimmer, faster to load and easy to work and setup :) Hope you guys like it Site: http://codebugapp.com/

I am excited to introduce my solo project, a platform built with the frontend development community in mind. It's an interactive environment aimed at refining debugging skills through exposure to real-world bugs. This project stems from the need for a hands-on, practical method of learning to debug. The site features a variety of intentional bugs for users to solve, mirroring the types of challenges faced in professional settings. Over the coming weeks, I will be adding many more exercises and new features to enhance your learning experience further. Check out CodeMender at…

My partner reviews a lot of P&IDs (piping and instrumentation diagrams) and the adjacent files involved (excel, docx, pdfs, acd/l5x, etc). In his company, these are usually done in Bluebeam. It's really hard to see the diff + keep track of all the revisions resulted by these iterations. They end up storing files like "rev3_final_redlined.pdf". We've been looking for something close to Github to do these reviews, but haven't found one easy enough for folks with no CLI experience to understand and use (happy to check out more tools if you know any). So I built withkord.com to help with…

Ladies and gentlemen of a Lisp persuasion, Clojurians and Clojuristas, followers of the paren and everyone else covetously eyeing the greener grass, I made an open-source thing that I would like to share with you. My elevator pitch is that it'll make you forget all about regular print debugging in 10 minutes straight. The slightly longer pitch is this: #>(tag'n'trace any Clojure(-Script) form to `tap>` and Portal with automatic last-input function replay on eval, instant re-render and hassle-free insertion of traced data into the REPL) And before I end up pasting half the README here in bits…

I love Claude Code but got tired of having nothing to do while I waited for sessions to finish, and managing multiple sessions on the command line was getting annoying and I kept losing track of the tabs. I originally built a quick and dirty version of this for my own use, but decided to polish it up and make it open source. The idea is that you should be able to do all your agentic coding without leaving the tool or needing to go back to a traditional IDE. You can view the diffs, run your program, and merge your changes back. I support OSX and Linux right now, but could add Windows support…

Sometimes, I come across a handy tool or a frustrating issue in my daily workflow. If it's both, I might write a small program in a language I’m comfortable with to solve it. Except for ELisp... For some reason, it annoyed me so much that I couldn't stop writing in it. First, it was simple config tweaks, then small patches, and before I knew it, I was enjoying it. I ended up creating a few packages, and of course, with each one, I’d hit a new problem, push the old one aside, and start fresh. Just hoping I don’t forget to go back to it later. Well, I didn't and I'm slowly revisiting,…

I’ve had this idea for a new code editor chord grammar bouncing around in my head for over 2 years, and now I can finally release v0.1 of ane. You can run it one-shot from scripts or agents (`ane exec —chord…`) or use its full-on TUI editor. ane is pure Rust, and integrates tree-sitter and LSP to provide a pleasant and predictable terminal code editing experience. I’d love folks to try it out and give feedback! Thanks :)

Hello HN, I am building a devtool to understand existing codebases. The idea originates from my time at big tech as well as various attempts to get involved in open source projects. When I was in college I wanted to improve my coding skills by contributing to opensource projects. I would pickup a bug or feature request but I always found myself stuck at the very first step. I did not understood where and how to begin contributing. I once submitted a patch in firefox which was labeled "Good first issue" but that was still very handheld. The assigner told me exactly which files I need to…

Howdy friends. I've been a zero to one product manager for 12 plus years and along the way I kept borrowing pieces from different discovery frameworks until I had a methodology of my own, one that actually raises the odds of an idea succeeding. This does not replace user interviews obviously, but it leads you in the right direction. Looking forward for your feedback

Hi HN, I've been working on this for a while and it was hard to decide when to stop, either on the way information is presented or when to stop with adding entries. It's not meant as a blog, but rather as a reference that keeps growing. Link: https://thehardparts.dev Currently I've created 4 main section: - Failure Modes: ways project go wrong - Red Flags: early signals that are worth taking seriously - Tech Decisions: common and not so common trade-offs for hard choices - Playbooks - guided approach for situations that repeat I've also focused on creating links between them to…

I'd like to share a new workbench I've been working on called DiffCAD. Coming from a software engineering background, not having the ability to properly diff my CAD model changes was driving me crazy. This project scratches my own itch, and maybe someone elses', too! I'm open to feedback, ideas, and contributions. Cheers!
