3D QR Codes

news.ycombinator.com Erik Demaine 2025-10-05 03:20:33

3D QR Codes Erik Demaine & Martin Demaine, 2025 In this exhibit, we're experimenting with the limits of QR (Quick Response) codes, in particular new ways to construct QR codes from physical material. Most of our QR codes are built from several layers of material (wood, paper, or acrylic), where each layer is a single color. Building in this way has an interesting constraint: each layer must be a connected piece of material. We use a greedy algorithm to find the most white pixels that can appea

These secret Netflix codes saved me from canceling my subscription - here's why

Gmail's backup codes are useless to access account

news.ycombinator.com Unknown 2026-01-05 03:32:55

Ok, I have a work account on Gmail. Having the experience of being locked out of Gmail previously (endless loop of "You are entering the correct password but we're not sure that it is you, try again later"), I created a 2fa via Google Authenticator and set up Backup Codes and thought I'm safe from them asking me to sign in on another device or enter sms code (I don't carry that phone with me). So, one sunny day I decided to add standard iOS mail app to this account, and lo, an hour after connec

Whistleblower warning: 2FA codes sent via SMS are trivially easy to intercept

techspot.com Shawn Knight 2026-02-27 20:12:00

Weak Link: Two-factor authentication is designed to harden device security and make unauthorized access even trickier for bad actors. In the imperfect world we live in, however, there's almost always a weak link, and one popular delivery method for 2FA is no exception. Many implementations of two-factor authentication involve sending a one-time passcode to the end user via SMS. Once entered, the user is logged in and it's business as usual. The problem is the inherent weakness of SMS, and the f
