Claude Max: The "Weekly" Limit Resets Every 72 Hours, Not 7 Days

Background

Claude Pro/Max plans expose a usage API at https://claude.ai/api/oauth/usage that returns two utilization counters:

five_hour.utilization — a rolling 5-hour window (well documented)
seven_day.utilization — described as a "weekly" cap

The seven_day object also contains a resets_at field. Monitoring this field over ~11 days (June 9–20, 2026) revealed that the "weekly" limit does not reset every 7 days — it resets every 72 hours.

Debian Trixie and the New deb822 Format for APT Sources

Introduction

Since February 2025, Debian 13 (Trixie) and APT introduced the deb822 format for managing APT sources. This new format replaces the traditional /etc/apt/sources.list file with the more structured and readable /etc/apt/sources.list.d/debian.sources file.

This change was introduced by APT, starting with an update that enabled users to run:

apt modernize-sources

This command automatically converts the old sources.list format to the new deb822 format.

hi, i'm daniel. i'm a 15-year-old high school junior. in my free time, i hack billion dollar companies and build cool stuff.

3 months ago, I discovered a unique 0-click deanonymization attack that allows an attacker to grab the location of any target within a 250 mile radius. With a vulnerable app installed on a target's phone (or as a background application on their laptop), an attacker can send a malicious payload and deanonymize you within seconds--and you wouldn't even know.

I'm publishing this writeup and research as a warning, especially for journalists, activists, and hackers, about this type of undetectable attack. Hundreds of applications are vulnerable, including some of the most popular apps in the world: Signal, Discord, Twitter/X, and others. Here's how it works:

Cloudflare

By the numbers, Cloudflare is easily the most popular CDN on the market. It beats out competitors such as Sucuri, Amazon CloudFront, Akamai, and Fastly. In 2019, a major Cloudflare outage k
