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/rezyX0m April 17, 2026 at 04:37AM

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/wHUnbuk April 17, 2026 at 02:02AM

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

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/GBA8cto April 16, 2026 at 08:08PM

Show HN: I built a Wikipedia based AI deduction game https://ift.tt/OY7WGhs

Show HN: I built a Wikipedia based AI deduction game I haven't seen anything like this so I decided to build it in a weekend. How it works: You see a bunch of things pulled from Wikipedia displayed on cards. You ask yes or no questions to figure out which card is the secret article. The AI model has access to the image and wiki text and it's own knowledge to answer your question. Happy to have my credits burned for the day but I'll probably have to make this paid at some point so enjoy. I found it's not easy to get cheap+fast+good responses but the tech is getting there. Most of the prompts are running through Groq infra or hitting a cache keyed by a normalization of the prompt. https://ift.tt/H3UMtd0 April 16, 2026 at 04:13AM

Show HN: Jeeves – TUI for browsing and resuming AI agent sessions I made Jeeves to search, preview, read through, and resume AI agent sessions in your terminal. It shows sessions across claude and codex in a single view, with more AI agent framework integrations to come. https://ift.tt/I9eNEw3 April 15, 2026 at 11:31PM
