NVIDIA shows how to fine-tuneNemotron-Nano-9B-V2to handle new CLI tools - without touching real user data. The trick? A mix ofsynthetic data,reinforcement learning with verifiable rewards (RLVR), and their home-grown trainer stack:NeMo GymplusGRPO. The result: an LLM agent that adapts fast, plays ni.. read more

Datadog just droppedBits AI SRE, an autonomous agent that thinks more like an SRE than a chatbot. It doesn't just regurgitate summaries - it investigates. It builds hypotheses, tests them against telemetry, and chases down actual root causes. Older tools leaned hard on LLMs to summarize alerts. That.. read more  

NIST locked in itsPost-Quantum Cryptography (PQC) standardsin August 2024. The countdown’s on: U.S. federal systems need to make the leap by 2035. Wiz jumped early with aPQC Security Framework. It scans for shaky encryption, maps your crypto assets, and flags what’s PQC-ready, all cloud-wide, using .. read more  

A recent change to 1.1.1.1 accidentally altered the order of CNAME records in DNS responses, breaking resolution for some clients. This post explores the technical root cause, examines the source code of affected resolvers, and dives into the inherent ambiguities of the DNS RFCs... read more  

A dev built a custom SSH proxy that punches through IPv4 limits without handing out public IPs like candy. Their trick:shared IPv4s with per-user relative IP mapping. It maps incoming SSH traffic to the right VM using thesource IPandpublic key combo. No Host header? No problem. They sidestep that ho.. read more  

Bare metal ops aren’t what they used to be. The game’s gone full stack:API-driven provisioning,declarative workflows, andconfig convergencenow run the show. Tools likeMAAS,Foreman,Ironic, andTinkerbelltreat physical servers as programmable units. Real hardware, real APIs. Meanwhile,Kubernetes-native.. read more  

A new writeup lays out a layered plan to keep secrets out of logs, no silver bullets here, just ten solid "lead bullets" that actually stack. Think of it as defense in depth for log hygiene. Highlights include: Type-safe domain primitives for secrets, Taint-based static analysis, Read-once secret wr.. read more  

Go gets big props for its built-in concurrency model withgoroutinesandchannels, which make lightweight, scalable parallelism easy and ergonomic. The author criticizes Go's type system for lacking things likeenums, closed type sets, and tuples, making certain patterns awkward compared with Rust's ric.. read more  

An engineer cracked open YouTube’s “most replayed” heatmap. Turns out it runs onsampled view frequency arrays, client-sidenormalization, andSVG renderingstitched together withCubic Bézier splinesfor that smooth, snappy curve. Behind the scenes, playback gets logged with adifference array + prefix su.. read more
