HN Companion – web app that enhances the experience of reading HN
HN is all about the rich discussions. We wanted to take the HN experience one step further - to bring the familiar keyboard-first navigation, find interesting viewpoints in the threads and get a gist of long threads so that we can decide which rabbit holes to explore. So we built HN Companion a year ago, and have been refining it ever since. Try it: https://app.hncompanion.com or available as an extension for Firefox / Chrome: [0]. Most AI summarization strips the voices from conversations by flattening threads into a wall of text. This kills the joy of reading HN discussions.…

In plain words
HN Companion is a web app and browser extension that enhances Hacker News reading through keyboard-first navigation, thread summaries, and viewpoint discovery. It uses AI to identify interesting perspectives while preserving the conversational structure and voting patterns that make HN discussions valuable, rather than flattening threads into generic text. Available for Firefox and Chrome, it helps readers decide which discussion threads are worth exploring in depth.

- HFHN Follow – Follow Your Friends on HN2023 · val.town · ▲133
HN Follow lets you follow authors on Hacker News, and get email notifications when they post. It was inspired by alerthn.com and hnreplies.com. The app was built in an experimental style on Val Town. We’re trying to create a new web primitive that you can: 1. write like a function 2. run like a script 3. fork like a repo 4. install like an app This is our 5th iteration of this same “HN Follow” app. We launched the 3rd version here on Hacker News six months ago[1], but it was very kindly removed from the front page by dang in favor of us launching Val Town itself first, which we did in…

I made an iOS HN app to navigate large threads without getting lost2023 · apps.apple.com · ▲94I was struggling with navigating HN discussions using existing solutions, so I decided to implement a completely different approach, think of it as depth-first reading vs breadth-first reading. Visually it looks like swipeable stacks of comments and it offers several advantages over traditional interfaces: - Comment width doesn't get narrower no matter how deep in the comment tree you are - You always see the parent of the comment you're currently reading - Swiping allows you to move in and out of subtrees with animated transitions that you fully control - You can easily skip subtrees that…

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
