It's not you; GitHub is down again

GitHub has issued an alert regarding a service disruption where notifications are being delayed via email and text message. To keep users informed, GitHub is offering a subscription service for real-time incident updates. Users can opt-in for email alerts for every incident update or SMS notifications for the creation and resolution of issues. This service supports a vast global reach, including over 150 countries from Afghanistan to Zimbabwe. To enable SMS, users must perform a verification process involving a mobile number and a one-time password (OTP), ensuring secure and reliable communication during technical outages.

Claude Code for Infrastructure

Fluid is a specialized infrastructure automation tool designed to streamline development workflows through high-fidelity sandbox isolation. By allowing users to instantly clone VMs, Fluid provides a safe environment to test changes in isolation before they ever reach production. The system is context-aware, meaning it explores the host environment including the OS, installed packages, and CLI tools to adapt its behavior accordingly. Security and accountability are central features, offering a full audit trail where every command and change is logged for review. Furthermore, Fluid enhances reproducibility by auto-generating Ansible Playbooks based on the activities performed within the sandbox, bridging the gap between experimentation and production-ready infrastructure code.

Show HN: I built a macOS tool for network engineers – it's called NetViews

NetViews is a professional-grade network diagnostic and monitoring application designed specifically for macOS. The tool provides real-time dashboards that offer immediate visibility into every connection, allowing users to discover all devices on a network and track their uptime with custom alerts. Key features include Wi-Fi signal analysis, channel congestion monitoring, and noise level tracking to optimize wireless performance. Additionally, it offers deep-dive tools such as ping notifications, DHCP and DNS monitoring, VLAN tag analysis, and Cloudflare-powered speed tests. The software is available in Standard and Pro editions, following a 'buy once, own it' licensing model, with the Pro version offering extended history, timeline views, and advanced Wi-Fi audits to ensure comprehensive network optimization.

The Book of PF, 4th edition

The fourth edition of The Book of PF serves as a comprehensive guide for system administrators looking to master the OpenBSD packet filter, PF. This tool is a cornerstone of the OpenBSD, FreeBSD, and NetBSD network security ecosystems. The text covers essential modern networking challenges, including robust IPv6 integration, dual-stack configurations, and advanced traffic-shaping via new queues and priorities systems. Readers gain practical knowledge on creating complex rulesets for diverse network environments like DMZs and bridges. Furthermore, it details high-availability strategies using CARP and relayd, alongside proactive defense mechanisms against spammers and malicious actors. By exploring monitoring tools and visualization techniques, the book ensures that professionals can maintain highly responsive, secure, and controlled network infrastructures in an increasingly hostile digital landscape.

Show HN: Knock-Knock.net – Visualizing the bots knocking on my server's door

The website Knock-knock.net provides a real-time visualization of global bot traffic targeting unprotected servers. Often described as the background radiation of the Internet, these constant probes attempt to breach security using common usernames and passwords. The site tracks historic data, identifies offending ISPs, and analyzes password trends to reveal automated attack patterns.

The Missing GitHub Status Page

This project provides a comprehensive uptime mirror for GitHub, addressing the lack of aggregate uptime metrics on the official status page. By replaying Atom feed snapshots archived via Flat Data, the system reconstructs a detailed incident timeline and calculates minute-level downtime windows. The pipeline utilizes GLiNER2 to infer component tags based on grounded incident text, ensuring high accuracy in per-service reporting. As an open-source initiative, it offers historical data dating back to 2017 and allows community contributions to improve data mapping and reliability for GitHub users.

TIL: Docker log rotation

The author recounts solving a disk space issue caused by Docker's lack of default log rotation. Large log files consumed 25 GB of server space because container logs persist indefinitely. The solution involves configuring the json-file log-driver in daemon.json with max-size and max-file parameters, then recreating containers to apply the new settings.

Jails for NetBSD

This workflow demonstrates jailmgr and jailctl on NetBSD to provision isolated HTTP services. It covers bootstrapping, resource limiting, and ephemeral provisioning within a supervision model. The system provides process isolation and Prometheus-compatible metrics without requiring a container runtime or full virtualization, utilizing kernel-level resource accounting and security models.
