PostgreSQL's GSSAPI authentication relies on two server-wide settings: `krb_server_keyfile` points to a dedicated keytab file (never share the system one), and…

Tetragon v1.7.0通过Runtime Hooks在容器创建时同步通知agent，使policyfilter在进程执行前就绪，避免API server异步延迟导致的策略漏事件或误放行。支持CRI-O OCI hooks和containerd NRI两种方式，agent不可达时可按namespace配置fail-open或fail-closed。无hook时仅保证best-effort，不保证策略在容器启动前生效。

Grafana Labs has announced general availability for two tools that let AI coding agents query live observability data during development: the gcx CLI and the Grafana MCP server. Both allow agents...

本文深入解析HAProxy backend机制，涵盖负载均衡算法（如轮询、最少连接、哈希）在无粘滞会话时的选主逻辑；server maxconn限制并发连接，超出部分进入队列，超时或队列满则返回503；http-reuse策略控制连接复用；fullconn动态调整队列槽位，redispatch与backup实现故障转移。排障时需区分算法、队列、复用三层，并与Envoy进行对比分析。
