Felipe Huici explains how Unikraft achieves millisecond cold boots, stateful scale-to-zero, and extreme density for sandboxing AI workloads. He discusses isolation primitives, Linux kernel...

Airbnb redesigned its authentication architecture around server driven flows and policy based challenge selection. The new Flexible Authentication system reduced authentication related code by...

文章列举了Percona博客上关于数据库技术的最新文章，涵盖PostgreSQL供应商锁定风险、AWS FSx复制延迟问题，以及MongoDB软件物料清单等主题。摘要聚焦于这些技术文章的核心内容，忽略无关页面元素。

MongoDB宣布支持RHEL 10及其衍生版和Debian 13，涵盖x86_64与ARM架构。该更新由Percona提供，旨在扩展兼容性，确保用户在新系统上顺利运行MongoDB。

本文介绍Linkerd 2.20策略模型，核心是三类CRD：Server声明端口入站策略，AuthorizationPolicy定义访问授权，MeshTLSAuthentication指定认证身份。policy容器负责入站策略推送，destination控制器处理出站发现。排障时需区分403拒绝、TLS错误、无端点等不同故障域，避免混淆策略与发现问题。

Microsoft has made the Azure DevOps Remote MCP Server generally available, offering a hosted endpoint into work items, repos, and pipelines with nothing to install. Claude Desktop, Claude Code,...

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。
