Show HN: Pyra – a Python toolchain experiment inspired by uv and Bun https://ift.tt/KvHmuUa

Show HN: Pyra – a Python toolchain experiment inspired by uv and Bun I’ve been working on Pyra for the past few months and wanted to start sharing it in public. Right now it’s focused on the core package/project management workflow: Python installs, init, add/remove, lockfiles, env sync, and running commands in the managed env. The bigger thing I’m exploring is whether Python could eventually support a more cohesive toolchain story overall, more in the direction of Bun: not just packaging, but maybe over time testing, tasks, notebooks, and other common workflow tools feeling like one system instead of a bunch of separate pieces. It’s still early, and I’m definitely not claiming it’s as mature as uv. I’m mostly sharing it now because I want honest feedback on whether the direction feels interesting or misguided. https://ift.tt/mB8Hy2J April 18, 2026 at 03:20AM

Show HN: Waputer – The WebAssembly Computer https://ift.tt/SCoIkZw

Show HN: Waputer – The WebAssembly Computer Waputer is an operating system that runs entirely in the browser. When you visit the website at https://waputer.app , a kernel written in JavaScript sets up a filesystem and launches a WebAssembly program, which in turn talks to the kernel to handle the display and input. A purely terminal-based version is at https://waputer.dev . My original intention was to create programs that run in the browser that have a lot more in common with the desktop. The traditional "hello world" program is not really suited for the web. Waputer changes that. The GitHub repo at https://ift.tt/Byj60xC gives a very brief overview of compiling a C program and running it on Waputer. There is a blog available from the main site that has a long-form explanation of Waputer and my motivations if you want some additional reading. https://waputer.app April 17, 2026 at 11:16PM

Show HN: Spice simulation → oscilloscope → verification with Claude Code I built MCP servers for my oscilloscope and SPICE simulator so Claude Code can close the loop between simulation and real hardware. https://ift.tt/lUZDjoI April 17, 2026 at 06:07AM

Show HN: Tracking Top US Science Olympiad Alumni over Last 25 Years Interesting to see that the entrepreneurs from more recent years tend to be doing well relative to years prior. Some interesting future directions could be: - Expanding search to be global and include more competitions, like biology and chemistry - Improving search so less unknown results - Showing insights, like trends over the years Kudos to Perplexity Computer for making this https://ift.tt/xOmPtdW April 17, 2026 at 03:32AM

Show HN: Marky – A lightweight Markdown viewer for agentic coding https://ift.tt/3jKpfOc

Show HN: Marky – A lightweight Markdown viewer for agentic coding Hey HN, In this age of agentic coding I've found myself spending a lot of time reviewing markdown files. Whether it's plans or documentation that I've asked my agent to generate for me, it seems that I spend more time reading markdown than code. I've tried a few different solutions to make it easier to read such as Obsidian however I've found their Vault system to be quite limiting for this use case and I've found TUI solutions to not quite be as friendly to read as I've wanted so I made Marky. Marky is a lightweight desktop application that makes it incredibly easy to read and track your markdown files. It also has a helpful cli so you can just run marky FILENAME and have the app open to the md file that you pointed it at. I've been using the daily over the past week and I really enjoy it so I figured I'd share it. Here's a video if you want to check out a demo: https://www.youtube.com/watch?v=nGBxt8uOVjc . I have plans to add more features such as incorporating agentic tools such as claude code and codex into the UI as well as developing a local git diff reviewer to allow me to do local code review before pushing up to git. I'd love to hear your thoughts and any feature suggestions you may have :) https://ift.tt/PV3E1N8 April 16, 2026 at 09:38PM
