![]() If I’m working it’s a great way to quickly play around with APIs of various kinds, and when I’m not it’s usually the first thing I reach for when I want to try out an idea. I have a notebook server running 24/7, which I originally fired up to do some data science/ML (everything from an early version of my COVID dashboard to RSS feed classification) and kept because it turned out to be an excellent notebook/scrapbook/sandbox. ![]() Without further ado, and in no particular order, here’s a quick run-down of the above (and a few other doodads): Jupyter This is where a lot of my tinkering starts. It’s still recognizable, but believe me, it’s less than 5% the original size: WhatĪll the apps are accessible from an ultra-lightweight, custom home page I based off a popular “start page” layout ( SUI), after removing 100% of the back-end, 99% of all the JavaScript and 80% of the CSS crud. They sort of took a life of their own since, and I use some of them daily for managing my media, general tinkering, prototyping stuff and occasional troubleshooting, but some became a sort of bridge between my Windows work machines (where I keep zero personal stuff) and my Macs and iOS devices. I started setting up various applications on these as a complement to the Synology built-in services, which include Time Machine, our home photo archive and an IMAP server where I keep a randomly updated copy of my personal e-mail. So it compares favorably to 1U in overall volume, if you will, and is nothing like the massive setups some of my friends have at home. ![]() It’s all surprisingly compact, and if I were to measure it in rack units it would probably take 4U in height solely due to the height of the Synology, but less than a quarter of a rack’s typical depth. …all run in a closet away from my office, wired up via unmanaged, zero-hassle Gigabit switches. My home automation setup on a Pi 4, which runs a few dozen “micro” services managed by piku.A bunch of containerized applications on my Synology, managed via its built-in Docker UI.A couple of Z83iis acting as media server and a development box, running docker-compose with very strict CPU, RAM and swap limits.An i7 KVM box (my former hackintosh) with a relatively puny 16GB of RAM, running a mix of LXD containers and actual VMs (including Windows) across a few consumer SSDs (yeah, I know, not really datacenter-grade, but it works).Hardware-wise, now that I gave away my ageing Raspberry Pi 2 Kubernetes cluster, the entire setup is neither cool nor much to look at, and consists of: I’ve been meaning to write about it for months but never got around to it, and I guess today’s as good a time as any. Some would call it a “homelab”, but it’s more of a set of (mostly) web-based tools I run on the boxes in my server closet. ![]() This may seem a bit weird, but the pandemic brought to my daily computing life a fair amount of on-premises services. ![]()
