My retired dad and I made a daily, somewhat difficult, quiz
My dad makes the questions, I made the site. I think the genre and the level of difficulty is suited for HN. Hope you enjoy. (I promise no AI-generated questions, they are all hand made!).
In plain words
A daily quiz site featuring hand-written questions created by a retired person and developed by their adult child. The quiz focuses on challenging questions designed for readers of Hacker News. Each day presents new questions across various genres and difficulty levels, all manually crafted rather than generated by AI. The site offers a straightforward quiz experience without additional features or premium offerings.

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.
- WLWayback Letter - Looking back at 5+ years of Hacker News2012 · ▲59
I just sent out my 100th issue of Hacker Newsletter and announced my newest newsletter: Wayback Letter - http://www.waybackletter.com/ In either a daily or weekly version, you'll get links to great HN articles from the past five years. A great way to see how HN has grown and changed, plus see what was going on at different times. Lastly, there are a ton of great reads to learn from that I never saw the first go around. Would love to get feedback and my goal is to expand this past HN in the future.
- OWOur weekend project - HN Showcase, browse "Show HN" posts2011 · ▲63
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…

I had an itch to build a weekend project, and I've noticed that a lot of Ask HNs often go unanswered, so I built AnswerHN as a simple way to see recently asked, but as yet unanswered, questions on Hacker News.
- RMReview my startup: Quora, a topic based question and answer site2010 · ▲55
Link to sign up: http://quora.com/hackernews Quora is a question and answer site focused on getting really high quality, authoritative content on any topic that people are interested in. The big idea is to try to get every question page to be the best possible resource for anyone who wants to know about the answer. One way to think about it is as a cache for the research that people compile by searching the web or asking others. The feeling you get when you see a Wikipedia article and you think "Oh, that's going to have all the information I want about that" is the feeling we want to create…
- SHShow HN my Hackathon Project: Visual Craigslist w/ HN's algorithm2011 · 5thavenue.chartboost.com · ▲42
The concept was to rethink the way we browsed Craigslist and shopped online. The main section, the "homepage" is a tree map of recent craigslist posting sorted by popularity using a slightly modified version of Hacker News' ranking algorithm. The newest page is a masonry view of the realtime stream of the craiglist posts as they are added to the system (much like Hacker News' newest page.) The top page is the masonry view version of the homepage. The game page is a FaceMash-like game for the posts, which influences the overall scores and popularity of items.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Built a ~9M param LLM from scratch to understand how they actually work. Vanilla transformer, 60K synthetic conversations, ~130 lines of PyTorch. Trains in 5 min on a free Colab T4. The fish thinks the meaning of life is food. Fork it and swap the personality for your own character.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
