Cómo un espejo en Netlify mantiene webs accesibles durante bloqueos de LaLiga a Cloudflare

·8 views

Las operadoras españolas bloquean durante los partidos de fútbol direcciones IP de Cloudflare por orden judicial, lo que deja inaccesibles también cientos de miles de webs legales que comparten esas mismas IP. Los autores de un curso sobre MCP describen cómo siguen operativos: durante cada partido el DNS se redirige automáticamente a un espejo estático en Netlify. El sistema consulta los horarios de Primera División, abre ventanas de bloqueo alrededor de cada encuentro y renueva los registros DNS y el certificado TLS de forma programada. Las rutas dinámicas del servidor MCP y el inicio de sesión se reenvían mediante un proxy firmado al Worker de Cloudflare, que solo atiende peticiones validadas. Los datos citados de OONI indican que, entre enero y junio de 2026, más de 500.000 dominios de Cloudflare sufrieron bloqueos en al menos una ocasión.

Editing a running Bash script in place can crash or misexecute it

A developer reported that adding a comment to a shell script that was actively running caused a sixteen-minute job to fail with a syntax error. Bash keeps a byte offset into the open file rather than a line number, so changing the file mid-execution makes it resume at the wrong position. A simple demonstration showed a stray command running and a line executing a second time. The fix is to write a new version to a temporary file in the same folder and rename it over the original, since a running process holds the old file by its inode. In-place write methods such as shell redirects are the ones that cause this problem.

Fragmented school attendance records cause morning confusion, argues data-consistency case

A DEV Community piece contends that school attendance problems stem from the same student-presence fact being recorded across paper registers, staff chats, and office spreadsheets without syncing. The author frames this as a distributed-systems issue lacking a single source of truth, with humans acting as the message bus. Suggested fixes include one authoritative attendance record tied to a stable student ID, marking at first-period roll-call, and typed statuses such as absent, late, or leave. The article also promotes OROO Campus, a free school ERP platform, as a tool to centralize attendance alongside other school management functions.

System Design Basics: Scaling, Sharding, and the Trade-offs Architects Face

A startup's single-server API handled early growth well, but a viral surge tripled traffic and repeated vertical upgrades eventually hit a hardware ceiling. The resulting single point of failure caused a six-hour outage on the company's busiest day. The article explains that vertical scaling is simple but limited, while horizontal scaling has no fixed ceiling yet requires stateless applications and a different architecture. It also covers load balancing and the practical advice to scale vertically until costs rise, then design for horizontal distribution. The core message is that architectural choices must be made before traffic forces them.
