Service mesh is a blazing hot topic in software engineering right now and rightfully so. I think it’s extremely promising technology and I’d love to see it widely adopted (in cases where it truly makes sense). Yet it remains shrouded in mystery for many people and even those who are familiar with it have trouble…
In Ukraine suicide drones strike critical infrastructure regularly. Some outages are caused directly by the attacks - destroyed power plants, substations, transformers, power lines, some are scheduled in advance - power grid wasn’t designed to work while some of its power plants and transformers are destroyed and are…
Microservice architecture paradigm fits well within the Unix’s first principle/philosophy: “Make one program do one thing well”. We l...
What nginx logs actually prove about AI traffic from ChatGPT, Claude, and Perplexity, plus why Google's AI crawlers leave a different signal than the others.
In recent months, there has been a resurgence in the usage of the term “web3”: a nebulous term that (like it or hate it) has suddenly become a banner for much of the innovation happening in the space of blockchain and distributed ledger technology. The term has been around for a while (since 2014 when Gavin Wood…
Putting your IT infrastructure into the cloud seems to be the "in" thing. It's been around for a while, of course. And, like most things rel...
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
DISCLAIMER: If you are in no way familiar or comfortable with the Terminal, this is not for you.
It all started with the big bang! We nearly lost 33 of 36 disks on a Proxmox / Ceph Cluster; this is the story of how we recovered them.
Here are some tips and tricks that I learned the hard way when developing and deploying web applications written for node.js using Docker.
This blog covers various issues I encounter and the (sometimes creative) solutions I apply.
A short case study breaking down the interesting design aspects of containers.
How to take snapshots of a directory and send to them as backups to S3 using Linux tools
The measure of a modern software engineer in our attention economy is easily calculable thanks to companies like Microsoft acting both as bastion and companion in demonstrating one's prowess.
The Python Package Index, or as most call it “PyPI” is a central part of the ecosystem of Python. It serves as a central registry of names, helping to prevent collision between different projects as well as the default repository that most Python users go to when looking for software. Though it has its issues (of…
Putting FreeBSD’s “power to serve” motto to the test. On Thanksgiving morning, I woke up to one of my web services being unavailable. All HTTP requests failed with a “503 Service unavailable” error. I logged into the console, saw a simplistic “Runtime version: Error” message, and was not able to diagnose the problem…

TL;DR: Some Linux distros and even different kernel versions within a distro have disabled IRQ time accounting. In such case, your monitoring tools will report zero time spent in hardware interrupt handlers (shown as %hi, %irq, hiq, etc). It’s easy to check how your kernel is behaving by looking at /proc/stat and you…
Yes, that familiar little PC peripheral. The one that toggles a single keyboard/mouse/display ensemble between two or more connected machines.
