A simple and standalone WebDAV server.

Every millisecond matters when you're in the critical path of API authentication. After two years of fighting serverless limitations, we rebuilt our entire API stack and slashed the end-to-end latency.

In this article, we’re going to cover a few things that might’ve puzzled you if you’ve been running your applications, especially Go applications, in Kubernetes:

- How Kubernetes and the Linux kernel handle CPU stuff for containers
- What the Go runtime does with CPU, and whether you should bother setting GOMAXPROCS
- Which metrics are actually worth paying attention to

Maybe you’ve seen some of these metrics before while keeping an eye on your applications, but didn’t fully know what to make of them. This should help clear that up.

VERT is a file conversion utility that uses WebAssembly to convert files on your device instead of a cloud.

TL;DR – After side‑by‑side testing on a 500 GB/7‑day workload, VictoriaLogs cut query latencies by 94 %, shrank storage by ≈40 %, and used < 50 % of the CPU & RAM we previously allocated to Loki. This post explains why we switched.

“Good communication” is one of those phrases everyone nods along to — until the incident hits, and suddenly comms unravel before your eyes.

So here’s what I actually mean when I say communication matters.

A high-throughput Java service was stalling. The culprit? Stop-the-World GC pauses were blocked by synchronous log writes to a busy disk.

pvc-autoresizer resizes PersistentVolumeClaims (PVCs) when the free amount of storage is below the threshold.

It queries the volume usage metrics from Prometheus that collects metrics from kubelet.
