URL: https://halocrypt.com/ Source: https://github.com/halocrypt We're particularly proud of our frontend, since we have used a framework we built ourselves!

Author here. This site lets you put in a username and get the users with the most similar writing style to that user. It confirmed several users who I suspected were alts and after informally asking around has identified abandoned accounts of people I know from many years ago. I made this site mostly to show how easy this is and how it can erode online privacy. If some guy with a little bit of Python, and $8 to rent a decent dedicated server for a day can make this, imagine what a company with millions of dollars and a couple dozen PhD linguists could do. Here's Paul Graham:…

I'd like to invite everyone to try out DontBeEvil.rip, an experimental search engine for developers. tl;dr $ alias rip="curl -G -H 'Accept: text/plain' --url https://dontbeevil.rip/search --data-urlencode " $ rip 'q=Heartbleed bug' DontBeEvil.rip is a year long experiment to see if a small team can build a developer-focused search engine that is self-sustaining on $10 monthly subscriptions. It works by only indexing high-quality resources that are relevant to developers. You won't get useless listicles because we'll never crawl them. Relevant urls are harvested from HN,…

We (Nick, Dens, Denzell, Fede, Drew, Aaryan, and Daniel) have been building HN Discovery, a discovery-focused search engine for Hacker News, in our spare time for the past 6 months and are excited to show it!

I noticed the who's hiring threads are very popular every month, so I decided to create a job board specifically for hacker news. You can tag jobs, search, view user's profiles and more. Tell me what you guys thing! Any feedback is appreciated.

Hey HN. I created this website. https://pj4533.com/hn-overlooked/ It's just a simple web app that discovers overlooked posts on Hacker News. I created it because I was often coming to Hacker News and realizing that I was missing a lot of stuff, and there just didn't seem to be an easy way to surface content that was interesting to me but just didn't bubble up to the top of the page. So I built this. I got the idea a while back, one night when I was recording (you can watch it here, it's pretty funny: https://youtu.be/FDyDb4sX30w?si=E3rby-DaGWA6gy0R ). But I…

Hi HN, As many of you already know, Google has discontinued their coding competitions and is shutting down the competitions website. Before it's gone forever, I've scraped everything I could from their website and set up my own archive. (Disclaimer: I'm not affiliated with Google besides participating in these contests years ago) While the initial version was ready back in March, today I'm rolling out big and hopefully the final update, so this might be a good time to share it with the HN community. Everything is static HTML and SQLite archives (with a very minimal backend to serve files…

So a while ago I was thinking it would be neat to build a site that had the most absolute utility. The idea I came up with was a site to store those little protips that are super useful, if you know them ahead of time. I hired a guy to work on it with me, and ClueDB was born: http://cluedb.com/ Please give it a whirl (it uses Twitter auth as login but doesn't tweet anything) and tell me what you think! (Various trivia: My first try at a project coded by someone else and "product managed" by me. Runs on Flask + MongoDB. Also, this is totally unrelated to my startup.)

http://www.hnshowcase.com Moses (nnythm) and I browse Hacker News daily. Show HN posts are some of our favorite parts of HN. We wanted to create a way to browse Show HN articles, even those that might not quite make it to the front page. We created http://www.hnshowcase.com last weekend to make discovering projects posted on HN easier. It searches all "Show HN" posts and generates a thumbnail view for each of them. You can sort by submission date, points, and number of comments, and navigate with left/right or j/k keys. We used the following technologies: HN Search API, Pyramid web…
