It integrates with Microsoft's products to complete tasks like autonomously asking meeting organizers to reschedule if there's a timing conflict. Pricing for Scout has yet to be disclosed, but customers will likely be charged based on how much they use the software rather than a flat subscription fee. Access will initially require a subscription to GitHub Copilot.

1-CLICK GITHUB TOKEN STEALING VIA A VSCODE BUG

A vulnerability in the webview security model of VSCode and github.dev allows attackers to steal sensitive GitHub tokens through a single malicious link. The security flaw comes from the way keyboard events are bubbled up from isolated iframes to the main window, enabling scripts to simulate unauthorized user input. These simulated keystrokes can be used to bypass publisher trust checks and install malicious extensions designed to exfiltrate private repository data and credentials.

CEO Avishai Abrahami explained that the currency pressure creates structural challenges since most costs are in shekels while revenue is in dollars.

INSIDE MICROSOFT'S PROJECT SOLARA

Project Solara is a platform for devices that run AI agents instead of apps. Its aim is to open up entirely new scenarios for computing. The current concept involves a desktop hub that sits beside a PC that responds to voice commands and a wearable badge with a fingerprint button that wakes an agent with one press. Microsoft envisions a future where hardware makers and other industry partners turn these reference designs into implementations of their own.

KARPATHY'S AUTORESEARCH FOUND A 3-YEAR-OLD BUG IN POSTHOG'S QUERY ENGINE (AND IMPROVED PERFORMANCE BY 11%)

Posthog pointed an AI agent at its query agent, fed it slow queries from production, and let it run overnight. The next morning, the team discovered that for almost three years, every query with a timestamp filter had not been using ClickHouse's primary key correctly. Fixing the issue cut the number of granules ClickHouse had to scan by 62% on the benchmark query and made the query itself meaningfully faster. This post discusses the team's setup, the bug itself, and PostHog's plans to automate this type of analysis.
