A developer built a razor-sharp TLS fingerprinting and blocking tool—all in kernel space—witheBPFandXDP. It hooks into incoming packets, scrapes TLS Client Hello messages, and cranks out simplified JA4-style hashes from their cipher suite lists. The fun part? It's running under tight stack limits, s..

Report URI closed the door on Redis CVE-2025-49844 fast. They rolled out ACL-based command blocks and jumped to Redis8.2.2, now running on a freshRedis Sentinel-based HA setup. To prove the fix stuck, they ran command counter checks and layered in enforced blocking rules—then pushed it all out fleet..

DigitalSociety ditched AWS and DigitalOcean. Swapped the comfort of cloud for full control onHetzner, built onTalos Linux. PostgreSQL? Now running onCloudNativePG. Traffic flows throughIngress NGINXwithExternalDNShandling the names. The payoff: monthly costs dropped from $449.50 to under $100. ARM v..

A fresh setup shows how to runModel Context Protocol (MCP) servers over HTTPinsideAzure Container Apps—stateless, serverless, and ready for real-time jobs like live forex conversion. It pipes in a live API fallback, adds caching, and speaksJSON-RPC 2.0overPOST. You can spin it up withBicep templates..

Pushing Kubernetes to 1M nodes isn’t just hardware—it's architectural judo. Networking flips to exclusive IPv6.Less chatter, more breathing room. etcd hits a wall.Write throughput stalls at scale, so they swap it out. Entermem_etcd, a Rust-built replacement pushing over 1M buffered writes per second..

Docker droppedBuildx debuggingfor VS Code. Set breakpoints in your Dockerfiles. Peek into image layers. Even jump into an interactive shell mid-build. It runs on theDebug Adapter Protocol, so editors likeNeovimandJetBrains IDEscan join the party too...

Docker just wired anAI guardrailstraight into its Hardened Image (DHI) pipeline. It scans upstream diffs, catches regressions before they ship, and stops bad logic in its tracks. Case in point: it flagged a logic bug that slipped past the usual coding copilots. A real fix landed upstream. Win for cu..

Istio 1.27.2 locks down TLS secret access in Gateway API mode. Now, both the namespace and service account have to match. No more half-matching your way in. It also drops the install order dependency betweenistioctl’s pilot and CNI. You can now install those in whatever order your chaos-loving soul ..

Resource ownership in Kubernetes isn’t just a nice-to-have anymore—it’s turning into table stakes. Teams are usingnamespaces, RBAC, labels, quotas, and admission controllersto draw clear lines around who owns what, how much they can use, and what rules they follow. Tools likeKyverno,LimitRanges, and..

OpenAI Codex just leveled up. It now hooks into Docker’sModel Context Protocol (MCP) Toolkit, which means it can tap directly into 200+ infrastructure tools—likeNeo4j graph databases—as if they were built-in features. With MCP, Codex doesn’t just code. It runs containers, spins up data models, eats ..
