eBPF is a powerful kernel-level programming framework that allows safe execution of custom code within the Linux kernel, attached to various events. This dynamic instrumentation capability, without requiring kernel recompilation, is a significant advancement for observability and security.
This article highlights several lesser-known PostgreSQL features, providing useful tricks that can improve daily database operations. I found the ability to grant permissions on specific columns particularly valuable for fine-grained access control.
This article details the surprising complexity of a seemingly simple hostname regex. I show how common assumptions about valid hostname characters, case-insensitivity, and hyphen usage are often wrong, especially with IDNs and punycode.
This is a solid primer on BGP, offering practical tools like BGPView, traceroute -A, and mtr -z to understand how to inspect BGP routes and autonomous systems directly from your workstation. It's a great starting point for any dev interested in playing around with networking protocols.
This series offers a crucial SRE deep dive into Linux Page Cache. I find it essential for precise capacity planning, debugging memory/IO issues, and building reliable services, covering key tools and kernel interfaces.
This article lays out practical SRE precepts for building reliable software, emphasizing an 80/20 approach to achieving significant reliability without impeding developer velocity. It offers solid advice across coding, deployment, and operations that I largely endorse.
