Hacker Smacker – Spot great (and terrible) HN commenters at a glance

Hacker Smacker adds friend/foe functionality to Hacker News. Three little orbs appear next to every commenter's name. Click to friend or foe a commenter and you'll more easily spot them on future threads. Makes it easy to scroll and spot the commenters you love to read (and hate to read).

In plain words

Hacker Smacker is a browser extension for Chrome, Edge, Safari, and Firefox that adds friend and foe marking to Hacker News commenters. Users click colored orbs next to commenter names to tag them as friends or foes, then easily spot these marked commenters in future threads. The extension includes a friend-of-a-friend feature: if both users have Hacker Smacker installed, friends and foes of marked commenters are also highlighted, helping readers quickly identify quality comments in long threads.

Hacker Smacker adds friend/foe functionality to Hacker News. Three little orbs appear next to every commenter's name. Click to friend or foe a commenter and you'll more easily spot them on future threads. Makes it easy to scroll and spot the commenters you love to read (and hate to read).

Safari extension: https://apps.apple.com/us/app/hacker-smacker/id1480749725 Firefox extension: https://addons.mozilla.org/en-US/firefox/addon/hacker-smacke... The interesting part is friend-of-a-friend: if you friend someone who also uses Hacker Smacker, you'll see their friends and foes highlighted too. This lets you quickly scan long comment threads and find the good stuff based on people you trust. I built this to learn how FoaF relationships work with Redis sets, then brought the same technique to NewsBlur's social layer. The backend is CoffeeScript/Node.js/Redis, and the extension works on Chrome, Edge, Firefox, and Safari. Technically I wrote this back in 2011, but never built a proper auth system until now. So I've been using it for 15 years and it's been great. PG once saw it on my laptop (back when he was still moderating HN, in 2012) and remarked that it was neat. Thanks to Mihai Parparita for help with the Chrome extension sandboxing and Greg Brockman for helping design the authentication system. Source is on GitHub: https://github.com/samuelclay/hackersmacker Directly inspired by Slashdot's friend/foe system, which I always wished HN had. Happy to answer questions!

    HackerNewsers,com, find other hackers near you2010 · ▲221

    There's been lots of discussion recently about finding other HNers to talk to / bounce ideas off / work with, some Google spreadsheets were set up to share details but they were soon vandalised. I had a spare afternoon yesterday (which turned into a long day) and here's the result: http://www.hackernewsers.com/ It's only open to people with HN accounts, it lets you post your biography, location, skills etc. Anyway, I hope you like it and find it useful.

    I was tired of opening 2 tabs for every HN link, so I made a userscriptJul 2026 · github.com · ▲433

    HN is great for the links people share, but a big part of the value I get comes from reading the discussion around them. I realized I was always opening the article in one tab and the comments in another, constantly switching back and forth. I figured there was probably a simpler way, so I threw together this userscript to merge the two. 1. Clicking a link from Hacker News opens the article with a side panel containing the discussion. It doesn't require your credentials, is resizable, and is easy to tweak if you want to customize it. 2. If you land on an article that has previously been…

    I've been working on and off on a Chrome Extension for Hacker News, the extension focusses on improved usability rather than design. I can almost guarantee that after a day you won't want to go back to regular Hacker News. Give it a try, features include: - Improved readability - Quick inline replies from comments page - Quick profiles with social network info when hovering over usernames - Filtering of stories based on terms and phrases / domain or user - Endless scrolling - Collapsible comment threads - Social sharing for Twitter, Facebook, Google+, Buffer Forks, improvements and comments…

  • Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…
