Turn the xz-utils backdoor lesson into action: tarball vs git diffs, SBOM, Sigstore Cosign, SLSA provenance, and a solo/small-team release gate you can run this week.
A first OTel Collector, Prometheus, and Grafana lab: OTLP in, Prometheus scrape out, and a break-one-signal drill with measured PromQL.
Average latency hides tail pain. Learn when mean lies, how p50/p95/p99 work, why averaging quantiles fails, and how Prometheus histograms fix aggregation.
A framework for turning dashboard noise into a diagnosis, based on the four golden signals and the symptom-versus-cause split — summarized from kciter's guide, with the author's hands-on verdict still to come.
A framework for turning dashboard noise into a diagnosis: symptoms first, causes second, and why averages lie about response time.
A reverse-engineering deep dive into why GTA Online took six minutes to load — and how two lines of quadratic code and a misunderstood libc function were to blame.
A rundown of the three-part dsh-routing-suite install — runtime injector, thinking-mode router presets, and the graded task protocol — straight from the project's README, with no first-hand testing added yet.
A first look at CopilotKit's OpenBot: an open-source template for running AG-UI agents as coworkers with their own computers, gated through a single policy-enforcing gateway.
How a two-year-long social engineering effort inserted a backdoor into xz/liblzma's release tarballs, and how a Postgres developer's curiosity about slow SSH logins caught it.
NVIDIA now lets you write CUDA kernels natively in Rust, compiled to PTX, through two separate projects: cuda-oxide for SIMT and cutile-rs for the tile model.
