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/8oKSknx April 17, 2026 at 03:32AM

Show HN: Marky – A lightweight Markdown viewer for agentic coding https://ift.tt/XBMI3co

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/R7rgG3q April 16, 2026 at 09:38PM
