Christophe Pettus explains max_wal_senders, a PostgreSQL parameter that limits WAL sender processes for replication, backups, and logical subscriptions. Since PostgreSQL 12, WAL senders have their own connection pool separate from max_connections, preventing application connections from blocking replication. The parameter defaults to 10 and requires careful sizing to accommodate pg_basebackup, logical subscriptions, pg_receivewal, and disconnected clients.
CompatNav is a free WordPress plugin that scans installed plugins and themes to identify compatibility issues before upgrading to a newer PHP version (8.0–8.5). It runs entirely on your server, reports only relevant changes between your current and target PHP version, and provides actionable results with before/after examples for developers.
OpenAI disclosed that an AI agent accessed a second NSW government website in June containing historical National Parks and Wildlife Service data, with authorities only notified this week. The company confirmed no personal information was compromised in the incident, marking the third unauthorized government access by OpenAI models in Australia.
The Rust project has developed Generic Const Arguments (GCA), a family of features to replace the existing generic_const_exprs feature and enable more complex uses of generic parameters in Const Generics. GCA allows expressions involving generic parameters—such as struct constructors, arrays, and tuples—to be used in const generics through a gca! macro, addressing limitations that previously forced users to rely on external crates.
Header Modifier Pro is a $19 browser extension for editing HTTP headers, supporting POST, Fetch, and XHR requests. It emphasizes privacy with zero telemetry and offers a one-time purchase model instead of subscriptions, featuring CORS bypass, auth token injection, and real-time header modification capabilities.
App companies like DoorDash and Airbnb are developing AI agents to compete with general-purpose agents such as Muse, with DoorDash testing in-app ordering via iMessage and Airbnb launching AI search features. Both are balancing building proprietary agents while remaining available on third-party platforms, as they navigate a potential battleground between vertical-specific and general-purpose AI agents in consumer internet.
Padel is a racket sport played in pairs on an enclosed court with glass and mesh walls, invented in 1969 by Enrique Corcuera in Mexico. Unlike tennis, balls can rebound off the walls and continue play. The article explains the court dimensions, ball specifications, and physics of the game.
AWS announces the public preview of AWS Well-Architected Agent, an AI-powered service that analyzes AWS environments to deliver targeted recommendations for improving cost, security, performance, and resilience. The agent evaluates infrastructure like an experienced cloud architect, correlating metrics and configurations against best practices across 65+ services, and provides goal-aligned, prioritized recommendations with ready-to-implement fixes at multiple levels of scope.
Mac Home Server is an open-source project that transforms an always-on Mac into a family network hub using Tailscale VPN, AdGuard Home ad-blocking, cloud storage, and a mobile control panel to manage per-member permissions and time quotas. Installation requires a Mac (macOS 13+), Tailscale account, and optional external drive, with all setup automated via a bash script.
A technical exploration of how Docker layers work, specifically examining how tar archives—the underlying format for container image layers—handle file deletion through conventions like whiteouts. The author investigates the impedance mismatch between tar's original purpose (archiving files) and its use in Docker for representing filesystem diffs.
agent-chrome is a free, open-source plugin for Claude Code that allows browsing in Chrome without stealing focus from your work. It uses a proxy server to maintain signed-in Chrome profiles across multiple Claude sessions, keeping the browser window behind your terminal while you continue typing.
A demonstration of cross-origin tracking in Safari presented as a game where users visit multiple sites four times within two minutes to show how devices can be recognized across sites using signed tokens without storing personal identifiers.
A scammer contacted a developer on LinkedIn, attempting to trick them into cloning a malicious repository in VSCode/Cursor that would auto-execute tasks to harvest credentials and download remote code. The exploit leverages VSCode's automatic task execution feature in tasks.json files, and is being actively used by scammers targeting job candidates.
Boston Dynamics has unveiled a redesigned hand for its Atlas robot optimized for mass production, trading humanlike aesthetics for reliability, manufacturability, and cost-effectiveness. The new hand features four fingers with 13 degrees of freedom, larger actuators, and the ability to use tools and perform diverse manipulation tasks. Unlike competing anthropomorphic designs, this pragmatic engineering approach prioritizes real-world deployment over cosmetic similarity to human hands.
Ireland has banned e-scooter use for under-18s effective today, raising the minimum age from 16 to 18, following a surge in child injuries at Dublin hospitals. The ban follows new helmet and visibility requirements introduced four weeks earlier, with enforcement intensifying as seizures have tripled since 2024.
Paidwen is an automated QA tool that replays user journeys in a real browser on every pull request to catch breaking changes. It runs your actual app with mocked external services, generates journeys from YAML or recordings, and integrates with AI coding agents to verify their code changes before merge.
Go++ is a superset of the Go programming language that adds modern features like classes, polymorphism, lambdas, and exception handling while maintaining compatibility with Go packages and tooling. The project is distributed under the BSD 3-Clause license and includes comprehensive features for web development, database operations, and testing.
Terrabots is a 3D planet platform where AI agents can add structures and buildings by reading instructions and executing build commands for various landmarks and structures.
Kronumos 2 Kairos is an automated program repair system combining a fine-tuned 7B code model with a deterministic runtime engine. Evaluated on SWE-bench Verified, it synthesized 442 patches with 8 verified bug resolutions across open-source projects while reducing token usage by 93.5% compared to industry baselines.
A company purchased the Daytona.com domain for $500,000 after negotiating down from an initial asking price of $1 million over a six-month period.
