Why Every IT Professional Needs a Home Lab

April 2, 2026 • homelab, proxmox, virtualization

A home lab is more than just a hobby - it is an investment in your career. Here is why I believe every technical IT professional should have one, and how Proxmox makes it easier than ever.

Inbucket - great tool for email testing

May 8, 2018 • continuous integration, email, go

A quick post to share a great tool I came across. It's called inBucket and it provides a self hosted alternative to mailinator. The premise is that you can dynamically send emails to any address and c...

LinOTP for two phase authentication

October 14, 2016 • authentication, linotp, linux

At work we just completed a migration from a closed source 2 phase authentication product (that ran on our Windows AD Server) to an open source product called LinOTP that integrates with Google Authen...

Command of the day: ncdu

July 19, 2016 • command line, linux, ncdu

Just a quick one for today. Have you ever wondered where all of your disk space has gone on a remote linux box I sure have. I'm a big fan of tools that provide a visual guide for disk space usage (tr...

HackerTV
I absolutely love this. HackerTV takes the videos Hacker News keeps recommending and broadcasts them 24/7 on themed channels, with the same schedule for everyone. Communal, linear television rebuilt out of the internet's favourite links, no account and no algorithmic feed required.
Leaflet 2.0 beta 1
Leaflet's first 2.0 beta ships as an ES module with its own TypeScript types. I took it for a spin close to home. Pick a pin on Canberra in ten stops to explore the capital, from Parliament House to the Mount Ainslie lookout.
Radiaverse – Global Radiation Map
I love getting lost in weird map sites, and this one plots community-contributed radiation readings from RadiaCode detectors around the world. The usual suspects are there: Pripyat and Fukushima. It does make you wonder where the readings come from though, since I would expect more around the old testing sites. The answer is probably the map itself: readings only exist where someone has carried a detector, and more people tour Chernobyl with a RadiaCode than holiday at Maralinga or Semipalatinsk.
China's First Frontier AI Export Controls: MOFCOM Announcement No. 48
This might be the beginning of the end for large Chinese open-weight models. The CSA unpacks MOFCOM Announcement No. 48, which proposes restricting export of frontier model weights, checkpoints and training know-how once a model clears 10^26 FLOPs of training compute, 2 trillion parameters, or a global top-10 ranking. API and SaaS access would not count as export, but deploying a restricted model outside China would, and an interim registration requirement is already in force.
Mistral Large 4 (Le Chonk) is now open weight
Le Chonk: Mistral releases a capable European open-weights model. Large 4 is a 1T parameter multimodal model that Mistral bills as the best open-weight option for coding, and the weights are now available to download and run yourself.
eMudhra Intermediate CA Compromise
Eight intermediate CA private keys were recoverable from their certificates, potentially enabling website impersonation for unpatched clients. Goddammit—Patch Tuesday was yesterday!
Permit Pending
SimCity, except every apartment block, bus lane and factory must survive zoning hearings, angry neighbours, lawsuits and the next election. I laughed; urban planners may cry.
How Abliterated Models Can Get You Pwned
ProjectDiscovery poisoned a 7B model for under $50; it behaved perfectly until a hidden trigger made a coding agent steal project credentials. A sobering local-AI supply-chain warning—but oh, please don't stop the fun!

this might be handy ...
If you don't run your own LLM proxy, how the fuck do you even know what's going on?
I'll have to have another crack at using pangolin for this exact purpose (I just couldn't get it working last time I tried!).
