Anonymous Dead Man's Switch
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…

What it does
Check in on your schedule; reminders on email, Signal, or Telegram; encrypted delivery to trusted contacts after your grace. Start free with Alcazar Security.
Wallets, passwords, legal docs, and messages should not vanish if something happens to you. A Dead Man’s Switch sends what your contacts need to the people you choose, automatically and encrypted, when you stop checking in. Wallets, password vaults, legal docs, business credentials: all locked behind what only you know. If something happens to you, your people can lose access for good. You pick a schedule: daily, weekly, or monthly. Check in on time and nothing happens. Miss one and we remind you on every channel you set before we do anything. Miss a check-in and you get a grace period with stronger reminders over time. Lost your phone or offline? You have time to respond. The switch only…from alcazarsec.com

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:…
Burner NoteJan 2026 · burnernote.com · ▲222In 2021 after getting thoroughly sick of Privnote, i built "Burner Note". Even though i didn't promote it in anyway other than a post here and a post on reddit, it ended up getting about 7000(ish) unique users per month. I kinda let it die about 18 months ago but i've resurrected it with some big upgrades. Most botable the app is now truly end to end encrypted (previously was just server side), and I've added dark mode as well as a few other bells and whistles. Feedback welcomed.

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
