Visualizing asymmetry in the 196 Lychrel chain (50k steps, 20k digits)

I’ve been experimenting with the classic 196 Lychrel problem, but instead of trying to push the iteration record, I wanted to look at the structure of the 196 sequence over time.Very briefly: starting from 196 in base 10, we repeatedly do reverse-and-add. No palindrome is known, despite huge computational searches, so 196 is treated as a Lychrel candidate, but there is no proof either way.Rather than just asking “does it ever hit a palindrome?”, I asked:> What does the *digit asymmetry* of th

Founders and Freelancers – Advice Needed

I help founders and teams get time back in their week by taking over the delivery + ops work that slows everything down, things like:-Projects with no clear owner-Roadmaps that only exist in someone’s head-Tasks piling up with no prioritisation-Zero visibility on what’s happening-Processes that should exist… but don’t-Clients or stakeholders losing confidenceI work remotely and plug in part-time or fractional as the person who cleans this up so you can actually focus on the work that matters.--W

Show HN: Python UI-ME – Bringing life to Python functions

I built python-uime, a simple tool that lets your Python functions say “make elegant UI forms out of me.” Add a single @ui_enabled decorator and UI-Me library instantly generates a clean web control panel for your script — with forms for each argument, type-inferred inputs, grouped tabs, global variable setters, rich JSON output. It is like a toned down version of python click-web. Or like Swagger UI, but for your Python functions, built entirely with vanilla HTML/CSS/JS + a small Flas

Show HN: Cynthia – Reliably play MIDI music files – MIT / Portable / Windows

Easy to use, portable app to play midi music files on all flavours of Microsoft Windows.Brief Background - Used midi playback way back in the days of Windows 95 for some fun and entertaining apps, but as Windows progressed, it seemed their midi support (for Win32 anyway) regressed in both startup speed and reliability. Midi playback used to be near instant on Windows 95, but on later versions of Windows this was delayed to about 5-7 seconds. And reliability became somewhat patchy. This made w

Show HN: Pinggy – A digital town square for your city

Pinggy is a location-based social app built around short, ephemeral text posts from people in your city. No likes, no followers, no algorithmic feeds - just a chronological stream of local conversations that disappear in 7 days.I built it because most social apps today optimize for reach, virality, and influencer dynamics, which often pushes out authentic, everyday voices. I wanted something smaller, more human — a digital town square where people in the same city can talk without the pressure o

Show HN: Clarion – AI system that rejects 97% of news into a high-signal digest

Hey HN — I built this because opening the news started to feel like drinking from a firehose. The signal-to-noise ratio keeps dropping, and most feeds optimize for outrage, not insight.Clarion is a small AI editor that reads thousands of articles weekly, filters hard (~3% make it through), and surfaces only progress-focused stories. The goal: a clear weekly snapshot of what’s actually moving forward, without the doomscroll tax.It runs on a simple stack: Vite + TS frontend, Supabase backend, auto
