Show HN: Ding Dong Doorbell – use a QR code as your doorbell

Hacker News - Tue, 10/29/2024 - 4:03am

I didn’t have a doorbell before (multiple reasons) and my house feels unwelcoming without one. So I built a doorbell app that uses a QR code - visitors scan the QR code to ring the doorbell and I get notified on my phone.

I’d love to get some feedback before I spend more time polishing the app. Please try it out and feel free to ask me any questions!

You can find the Android and iOS app links on the site.

Here is an example QR code you would put on your door. Give it a scan and say hello: https://www.thebacklog.net/img/2024/10/show-hn.png

Ask HN: What did Sony do wrong with PS3 signing?

Hacker News - Tue, 10/29/2024 - 3:57am

Background info: https://arstechnica.com/gaming/2010/12/ps3-hacked-through-poor-implementation-of-cryptography/

From the article:

> But when fail0verflow worked backwards from generated keys, they found out that a parameter that should have been randomized for each key generation wasn't being randomized at all. Instead, the PS3 was using the same number for that variable, every single time, making it easy to work out acceptable keys.

Which parameter are they talking about? Seed?
