A guide's working kit used to fill a bag: rented receivers, printed itineraries, a clipboard for roll call. Most of it now fits on the phone the guide already carries. Here is how we see the job changing, and what Your Next Tours does about it today.
Your messages got quantum-safe encryption years ago, your certificates did not. Why key exchange came first, and how signatures are catching up.
Q-Day is when quantum computers break today's public-key crypto. Why the estimates fell from 20 million qubits to 10,000, and how to read them.
Headlines say quantum computers beat supercomputers. That is not the same as breaking encryption. Here is the gap between the two milestones.
Encrypted traffic recorded today can be read once quantum computers arrive. What that means, why the timeline keeps shrinking, and how to tell if you are exposed.
Rented whisper radio sets cost money on every departure, travel in a case, and pass from ear to ear. Here is how Your Next Tours replaces them with the phones the group already carries.
security.txt (RFC 9116) is a plain-text file that tells security researchers how to contact you. What each field means, the file we publish at FirstPoint, how to sign it with PGP, and how to serve it correctly.
Chrome's privacy preserving prefetch proxy keeps requesting a file most servers never serve. What /.well-known/traffic-advice does, how to write one, and when a tiny JSON file can save your origin from unwanted prefetch traffic.
Your Next Tours turns a guide's phone into a live audio broadcast server: participants listen in their own browser over a local WiFi network, with live translation into 26 languages and no rental receivers.
