DevOps & Cloud

A comprehensive look at tick.pro: an ultra-fast, privacy-first, open-source developer toolkit for Unix timestamps, cron schedule intelligence, timezone conversions, date format specifications, and terminal-native curl APIs.

A comprehensive engineering guide to Confidential Computing: protecting Data in Use against compromised hypervisors, hardware memory encryption with AMD SEV-SNP and Intel TDX, cryptographic remote attestation, and zero-trust cloud deployment.

A comprehensive engineering guide to Carbon-Aware Computing: calculating the Software Carbon Intensity (SCI) specification, dynamically scheduling batch queues and ML workloads to follow renewable energy grids, and optimizing cloud architecture for sustainability and cost.

A deep architectural exploration of WebAssembly (Wasm) on the edge and backend: why WASI 0.2 and the Component Model are replacing microservice container pods, achieving sub-millisecond cold starts (<0.5ms), and enabling cross-language binary composability.

A deep technical guide to eBPF for backend and DevOps engineers: leveraging kprobes, tracepoints, and XDP for zero-code microservice tracing, diagnosing socket latency, and replacing bloated sidecar proxies.

Master server-side image compression on Linux with ImageMagick: progressive JPEG encoding, chroma subsampling (4:2:0), 8-bit PNG palette quantization, batch WebP conversion, and automated shell workflows.

A battle-tested sysadmin guide to reclaiming tens of gigabytes on Linux servers: pruning Docker BuildKit caches, clearing NPM/Pip/Composer/Go package caches, vacuuming systemd journals, and auditing root storage safely.

A masterclass in enterprise database resilience: replacing fragile logical dumps with continuous Write-Ahead Log (WAL) archiving to S3, pgBackRest automation, and sub-second Point-in-Time Recovery.

A masterclass in high-performance PHP: mathematically sizing PHP-FPM worker pools, switching to static process management, tuning OPcache bytecode buffers, and setting up the FPM status page.
