Products that do what Anonymous Dead Man's Switch does
Hey HN, I'm John from Alcazar. We just launched a Dead Man’s Switch that uses anonymous accounts instead of email+password. I'm a fan of Mullvad and their approach to accounts, so I copied it. But instead of 16 digits (53 bits of entropy), we generate 12 random words from the Monero wordlist (128 bits) and derive the account identifier+"password" using libsodium. The app is built on top of our existing Flare code and infrastructure. It uses SvelteKit, Shadcn, Tailwind CSS on the frontend, and FastAPI, SQLAlchemy, Celery on the backend. It’s hosted on Hetzner and uses Scaleway for sending…

We're 2 hackers out of NYC and we had tons of fun building Zapkast.com, our take on Social TV. We played with: - c/c++ for hacking our set top boxes, - ruby/rails for the rest api, - eventmachine/node/erlang for the xmpp api/real time backend, - ios/cocoa for the iPhone app, - redis & mysql for the datastores. We did everything ourselves, even the logo and UI :) Tell us what you think! http://zapkast.com

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…

Hello HN! Here's my November Startup Sprint project (coded in two days). http://hackerlunch.com It allows you to post your lunch plans and lets other hackers join you. I built this because I often see HN users are interested in meeting each other if they are in the same area. I am not a coder, so this version is very rough. If people use it, I will work with others to build a more polished version. I would love some feedback. What do you think? Is this something you will be using?

I put this together since I find myself switching away from the terminal to see if anything new popped up in HN. There might be similar ones out there, didn't bother looking. It was a quick experiment, which might end up with a few more features.

I built HackerBuddy.com with the idea of helping the Hacker News community get one-on-one help with fellow hackers that know their stuff. It matches up people that are good at a particular skill (Ruby on Rails, Python, beta-testing, general startup advice etc) with people that need that specialist help. All it does is swap your email address so that hackers can give fellow hackers one-on-one advice. I built the site as a way to learn Ruby on Rails, I'm still a bit green when it comes to coding so there's a very good chance that the server will fall over. Any feedback you guys have would be…

Hello! As soon as I saw eieio's https://onemillioncheckboxes.com/, I knew I wanted to try it out using Elixir. The original was created using Python and Redis (later Go and Redis) but this one is using just one Elixir server and HAProxy for SSL termination. It's also using S3 to show the overview page where all the checkboxes are drawn on a 1000x1000 canvas. The whole site is running on a 4 core 8 GB Hetzner VPS so I'm interested to see how it will hold up. This took an embarrassingly long amount of time to complete (the first commit was on July 23) but it was my first real…

I know everyone is a bit burned out on blockchain and cryptocurrency related stuff around these parts, but I've been working on as a side project for the last few months and thought you guys might be interested: https://cryptoempire.io/ It's still a bit buggy and incomplete (the mobile ux needs a lot of work, the leaderboard isn't functional yet, etc.), but I've reached a point where I'm not totally ashamed of sharing it :) Any feedback would be most welcome!

Hello. I made this project as an experiment in using key cryptography for user identity in a client server model, and for some future peer to peer projects that I am working on. I am looking for feedback, please let me know what you think. Also, Merry Christmas to HN! :-)

Hi HN, About two months ago, I was inspired by the events that began to unfold in Tunisia, Egypt, and then elsewhere, as everyday people started using the internet to organize revolutions against despots. I was amazed at their courage, using sites like Facebook which forces them to use their real name, or twitter which uses an account that can be easily tracked back to them. I thought that if there was a way they could use a site to communicate with a large audience, anonymously, they might be a bit safer. Graffitly is my attempt at that site. It's my first ruby on rails app, and there is…

I built this after one too many 3 AM wake-ups due to API outages. Existing solutions felt overpriced and overcomplicated for my small-scale needs. Key features: Simple, GitHub-inspired dashboard Free tier: 5-minute checks, email alerts, 30-day retention Premium tier: 1-minute checks, SMS alerts, unlimited retention Significantly more affordable than enterprise solutions Tech stack: Next.js frontend, Node.js backend, MongoDB, Stripe for payments. This is my attempt to solve the "sleep vs. downtime" dilemma for fellow indie hackers. I'd appreciate any feedback or feature suggestions. What's…

So I got so involved in setting up AdWords, tracking down WP security bloggers, etc. that I forgot to post it here and get you all to check it out and offer suggestions. It's only been out for a couple weeks or so though, so this still qualifies as "launch window", I guess. Check it out here: http://www.panic-press.com/ Promo code "show-hn" for a free month to try it out. It has 100 uses, so it shouldn't run out, but if it does, let me know.

We've set up DeekSeek R1 with a system prompt that attempts to censor the word PRIVATEKEY from its response. If you can get DeepSeek R1 to output that string (not in the reasoning, but in the final response), the system will reveal a private key which contains $1000 USDC. You will have a 50 token limit in the input. We will have a series of contests, sponsored by AI researchers, in order to learn more about prompt engineering and how LLMs interact with real money. Good luck! Edit: The money was claimed! Thanks for playing all. You can still play for fun. Stay tuned for the next one! Stats:…

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…

Hello HN, around October last year, I started to work on campaignkit.cc as a side project. It is a service to detect invalid and malicious email addresses. You can upload text files, and use the REST API or direct integration to retrieve a detailed report for each email address. End of March I added Stripe Payments and got my first paying customers via SEM. A coworker suggested starting a Show HN thread, so here we are :) I used golang for the backend since I wanted something lightweight with fast compilation times (coming from scala). For the frontend, I'm using Next.js and TailwindUI. On…

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…

A while ago I started this side project to test if I could build a rich User Interface that would have about the same level of responsiveness than a "SPA-like" app, but using only htmx[1]... I still have plenty of stuff in my roadmap, but today it's in a playable state and I thought it could be interesting to share it - as it may be a nice demonstration of a relatively rich user interface powered by htmx :-) --> https://zakuchess.com As for the stack: it's built mostly with Django, htmx and Tailwind CSS. It uses a SQLite database, and is hosted (for free) at Fly. The characters'…
