Alternatives
Products that do what Hoodmaps Meets 4chan does
I made this as a pair programming exercise with o1-preview. o1 did most of the heavy lifting, through high level prompts, but eventually I needed to diverge from it to get to completion. My initial prompt was: --- I'm making a web app: It's like 4chan, but each thread starts with a gps coordinate. People can only post text and images. I want to build it with flask and sqlalchemy. I want just the backend and data model that supports these threads, anonymous users, and users that can register a permanent username. Write as much of it as you can for me. --- This produced a fully scaffolded…

This is a little project I've been working on for a while in order to better learn Python. Although IRC may not exactly be the most exciting medium, I still find it to be fun and useful, this interest lead me to writing a bot. In doing this I realized that what would actually be more interesting would be if I had a framework. There may already be such a thing, certainly there are IRC libraries, but I don't know if they're well-suited to deploying bots. At any rate if for no other reason than the fact that I am relatively new to programming and eager to learn I decided to build a framework.…

This was more of a sandbox to play with Raphael and Flot than anything else but I think there are some interesting statistics in there. It'd be awesome to do this over time but I really don't have the spare time required.

Hi HN!, We're a group of High Schooler's who have made a website for an international cryptic hunt we have been organizing. Everything has been built from the ground up and has been open sourced. We'd love feedback on our work. And if it interests you, feel free to register and try a level or two! 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!

Hey everyone! I am excited to share updates on four of my & my teams' open-source projects that take large-scale search systems to the next level: USearch, UForm, UCall, and StringZilla. These projects are designed to work seamlessly together, end-to-end—covering everything from indexing and AI to storage and networking. And yeah, they're optimized for x86 AVX2/512 and Arm NEON/SVE hardware. USearch [1]: Think of it as Meta FAISS on steroids. It's now quicker, supports clustering of any granularity, and offers multi-index lookups. Plus, it's got more native bindings than probably…

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.)

Hey HN. I've just launched my very first webappp and would love your feedback. http://www.7bks.com It's a book list sharing website - kind of like playlists for bookworms. The site is built on pyton/appengine - and I learned to code in under 4 weeks to build the site. There's more details on the background of the site here: http://www.7bks.com/blog/179001 I've also published the full Python code for the site here: https://gist.github.com/670034 Feedback is really important to me and I want to work hard to make the site better so any and all suggestions are greatly appreciated.

URL: http://hipchan.com/ The story: after seeing this on HN http://news.ycombinator.net/item?id=1940089 and seeing a comment about 4chan, I decided that I could build something that embraces the 4chan idea. Even though the story today is 'social' I really think that anonymity will continue to have a place in future communities. It was supposed to be a weekend hack, and it was! 95% of the features were worked out in the weekend following, but somehow testing lasted till today... Primary feature: The ability to have * boards. For example: http://hipchan.com/#hn The Tech:…

Hello Hacker News! In the past few weeks I've been working on a side project that allows you to post anonymously a short message and a photo that is tied to your location. Other people can see posts around them in a radius of 1 kilometer. Posts are ephemeral and disappear after one day. That's all. It started as an exercise to try to write a geohash index and to try nodejs and Redis. I'm not sure if/how it could be useful. Maybe it could be used as a quick way of sharing something with someone next to you, or to leave a reminder for someone at a specific location. Or it could be abused…

As you can tell, it's heavily influenced by Mark Bao's threewords.me. The concept is simple, upload three pics and let your friends vote on them. In fact, I think I may have ripped the concept off a post about threewords.me. Anyways... Basically, I just wanted to build something stripped down to a core functionality and a little different from my usual projects. I've spent a lot of time polishing the flow and trying to make sharing an inherent part of the app. It's built on Ruby/Padrino/Sinatra, Postgres and uses S3 for image hosting. This is actually my first Ruby project coming from a pure…

Sup HN, So a couple of months ago I posted my OSINT app ShadowBroker here and got WAY more attention than I expected. Some of the feedback was brutal, but honestly, a lot of it was right, and it made the project a lot better. And sure, I had a blast tracking billionaire jets and yachts or discovering GPS jamming in Ukraine was a thrill, and so was watching CCTV feeds from London, along with ships, satellites, conflict zones, etc., but eventually it dawned on me…where does my OSINT dashboard actually go from there? What good is all of the telemetry if people cannot communicate with each other…

Hi! Long time reader, first time submitter. I've finallllyy got my first webapp online. It's been a long time coming, I started it over a year ago and just been an hour here, a couple of hours here, and a period of a couple of months of nothing. I first wrote it as a way to learn some python it sort of grew to fill a need I had. It's at a point now where I'd LOVE some feedback as I am going round in circules. Please, it's free, just hit the home page, plugin in a name/email and url you want to links checked on. If you use the name 'DeleteMe' I will remove the account after a week, so feel…

Try it at: ssh krnl.duetbrowser.com No sign up, totally free - no download. Let me know what you think. Prior art exists (brow.sh) but I wasn't satisfied with their graphical take. I wanted the raw, old skool terminal days of the early internet - BBS, and old green phosphor library comptuers - but running the modern web, with all the bells and jingle jangle whistles (JavaScript, etc). No funding, no VC, just 100% raw terminal fun. Not sure how long the demo will last, but try it out.

Hi hackers, long time reader, first time "real" submitter. This is by no means a revolutionary idea, or even execution, but rather something I've always wanted to do, just to see if I could write a good implementation of it. So without further adieu: http://ca.pitali.st/ Yes, it's just an URL shortener. Please check out the API and if there anything you like about it, please share, so I can take this feedback with me to my future projects. If there's something you REALLY hate, that's feedback too. Don't be afraid to hurt my feelings; this was put together in less than 4 hours to see if I…

I built over 3-4 weeks to solve my own pain point, picking up rust along the way. It has a browser version that works online/offline and cross platform desktop as well. It was a pretty intense sprint. About TreeSnap, well it simplifies this preparation of sharing code with Chat LLMs. In my use case, making o3 via ChatGPT a lot more cost-effective to use for these tasks compared to Cursor: How it works: Select files/folders → generates a single text bundle + ASCII tree Instantly shows per-file and total token counts (list & treemap views) Quickly trim unnecessary files or folders to…

I wanted to find a product idea to build. "Build things people want," right? So I thought, why not literally find people saying what they want? I wrote a script to collect thousands of Reddit posts where people are looking for a solution or complaining about a problem. Then I used GPT to filter out the noise and score each one based on how viable the idea seemed. Threw together a simple search interface so anyone can explore them. I was planning to build a more advanced paid version of this, but figured I'd share the raw version first to see if it's actually useful to anyone.

Hey HN! I made a completely open sourced alternative to Weights and Biases with (insert cringe) blazingly fast performance (yes we use rust and clickhouse) Weights and Biases is super unperformant, their logger blocks user code... logging should not be blocking, yet they got away with it. We do the right thing by being non blocking. Would love any thoughts / feedbacks / roasts etc

I have just launched a project that has been sitting on my hard drive 80% finished for the better part of a year. http://www.chatroulettespy.com It detects your 'anonymous' chat partner's IP address and performs a geolocation lookup on it to show the user the partner's approximate location on a map. I know the Chatroulette fad has peaked a long time ago (when I started this project), but there are still many people using it and its many clones. It was important for me to follow through on this one and not let it die on my hard drive like many projects before. I would appreciate any feedback…

My sister asked me if I can set up a site similar to jack.ventures for her a month ago. She said it was open source (https://github.com/Jack000/Expose) and should be easy and I just need to run a script (rolls eyes). I did that and two weeks later her friends saw it and want me to run the same script for them. So I decided to take some weekends to build something similar using nodejs/redis/mysql, put up a user registration page, user profile page and add some editing features. So now everyone can sign up without me having to run any 'script'. Just push the first…

Please have a look at www.socialeaks.com and tell me what you think. This is my first adventure in coding (my background is not CS). I started learning rails about a month ago via railstutorial.org. When I finished that, I felt the best way to continue learning would be to just build an app from scratch. I came up with this concept while observing how crazy the world had gone over WikiLeaks. I thought this was a funny idea. I also thought it would be fun to build! So, here I am. I built this in rails 3 and it is currently living on Heroku. It took me about two weeks to code, doing just about…

Hey everyone, my friend and I created a GitHub Wrapped video for developers to showcase their activity on the platform in a more fun way. The implementation is open-source (https://github.com/rendleyhq/github-wrapped-2024) if you're interested in how it was built. To get a bit geeky, we used masks, keyframe animations, luma key shaders to remove the background from the confetti video, and some other techniques. Also, everything is rendered directly in the browser!! I'm curious to hear your thoughts on the rendering performance, especially if you're running this on your…

After fine-tuning GPT for a personal project, I realized how tedious it is to write plain text in a massive JSON file. That's why I built this app for my own use, and I want to see if others could benefit from a tool like this as well ;)
