GitHub ships a one-click self-revoke for users whose credentials just leaked

You forwarded the phishing email to the security channel about ninety seconds too late. The laptop is already cooperating with someone else. Your personal access token, the one you minted "just for that one script", is on its way to whatever Discord pays for stolen tokens this week. Now what? For users on GitHub Enterprise, what was previously a clickthrough checklist you complete while your hands shake is now one button. On June 24 the GitHub Changelog announced a self-service credential revocation flow under Settings, Credentials. From that view a user can see counts of every credential they have generated or authorized through SSO, then revoke or delete all of them in a single action. Personal access tokens, SSH keys, OAuth tokens, SSO authorizations: gone together. What actually shipped Containment used to be a manual scavenger hunt. PATs sat under Developer Settings. SSH keys lived one tab over. OAuth apps you forgot you authorized two years ago hid behind a different submenu. SSO was its own world. In practice that meant during an incident you forgot something, and the something you forgot was the credential the attacker actually wanted. The new view collapses that surface onto one screen. Counts on one side, a revoke-or-delete-everything action on the other. Whoever wrote it had clearly pictured the 3am screenshot: a user who has just been told to "rotate everything" and has no idea where "everything" lives. GitHub frames this as a complement to an earlier enterprise-owner capability that lets admins with the "Manage enterprise credentials" permission bulk-revoke across one user or many. So there are now two pairs of hands on the kill switch: the user, and the org. (Whichever one notices first.) Why a pipeline owner should care Because users are the trust boundary you keep pretending is somebody else's problem. A leaked PAT in a CI pipeline is rarely a CI bug. It is a human who pasted the token into a script, then a laptop, then a sync folder, then a backup,

Building a Real-Time World Cup 2026 Bracket Predictor with Vanilla JS and GitHub Actions

Introduction With the World Cup 2026 group stage reaching its climax, football fans worldwide are speculating about who will make it to the finals. To make this experience interactive, I built a fully dynamic World Cup 2026 Bracket Simulator. Instead of just letting users click and choose winners, this app dynamically calculates ELO win probabilities and probabilistically generates realistic match scores (including extra time and penalties) based on team ratings. It also syncs with live match data in real-time. Live URL: https://worldcup-predict2026.github.io/champion/ Tech Stack: Vanilla JS, CSS3 (3D parallax), GitHub Actions, Python, football-data.org API Core Features & Technical Implementation ELO-Based Win Probability & Score Simulation Each team in the database is assigned an ELO-based strength rating. When a user runs the AI auto-prediction, the script calculates win probability and generates a realistic scoreline. Here is the goal roll algorithm (Poisson-like simulation) implemented in Vanilla JS: javascript function generateMatchScore(team1, team2, winner) { if (team1 === "TBD" || team2 === "TBD" || !winner) return null; const s1 = teamStrengths[team1] || 70; const s2 = teamStrengths[team2] || 70; const winnerIsTeam1 = (winner === team1); const strengthDiff = Math.abs(s1 - s2); const baseGoalExpected = 1.1; const bonusGoal = Math.min(1.8, strengthDiff / 12.0); // Goal weight based on ELO difference const rollGoals = (lambda) => { let L = Math.exp(-lambda); let k = 0; let p = 1.0; do { k++; p *= Math.random(); } while (p > L && k < 10); return k - 1; }; let gWin = 0; let gLose = 0; const r = Math.random(); if (r < 0.75) { // Regular time win (90 mins) gLose = rollGoals(baseGoalExpected); gWin = gLose + 1 + rollGoals(0.7 + bonusGoal); return winnerIsTeam1 ? ${gWin} - ${gLose} : ${gLose} - ${gWin} ; } else if (r < 0.92) { // Extra time win (AET) const normalGoals = rollGoals(baseGoalExpected); gLose = normalGoals; gWin = normalGoals + 1; return winnerIsTeam1 ?
