How a New Kernel Killed My CIFS Share Speed

Sat, 11 Apr 2026 12:00:00 +0100

The Symptom

qBittorrent would start a torrent at a decent 2-3 MB/s and then crawl to zero within a couple of minutes. I tested with an Ubuntu ISO where the tracker reported over two thousand seeders, and still only a handful of peers would actually connect. At the same time Jellyfin streams felt laggy, and a few other containers bind-mounting the same NAS share were doing everything a little slower than they should.

Tailbox: Split-Tunneling Through Mullvad via a Tailscale Container

Tue, 07 Apr 2026 20:00:00 +0200

What Is Tailbox

I spend most of my workday on a corporate VPN that owns the default route on my laptop. It needs to stay up for me to do my job, so tearing it down whenever I want to hide some other piece of traffic is not an option. What I actually wanted was this: keep the work tunnel up, and at the same time have specific browser tabs and specific shell commands exit through my home LAN via Mullvad. Split-tunnel in the browser and in the shell, not at the kernel route table.

Chat Control: 1984 Was a Warning, Not a Roadmap

Sun, 05 Apr 2026 12:00:00 +0100

George Orwell wrote his book 1984 as a warning, not an instruction manual. Apparently the EU Commission read it as the latter. Chat Control is the nickname for an EU legislative proposal that would force messaging apps, email providers and cloud services to scan every private message before it gets encrypted. The official pitch is “detecting child sexual abuse material.” The actual mechanism is client-side scanning of all your communications, on your own device, before the padlock even closes. The telescreen, but in your pocket.

VasttrafikT: A Telegram Bot and Mini App for Gothenburg Transit

Wed, 01 Apr 2026 15:00:00 +0200

What It Does

VasttrafikT is a Telegram bot (@vasttrafikt_bot) and an accompanying Mini App (vtt.tdwg.fi) for checking real-time departures and planning trips on Gothenburg’s public transit. I built it because I wanted something faster than opening the Vasttrafik app every time I needed to check when the next tram leaves.

Type /a brunnsparken and you get a live departure board. Type /r brunnsparken till lindholmen and you get trip suggestions. Or open the Mini App inside Telegram and tap your way through it.

Buy Me a Lambo: The Ultimate CSS Crypto Donation Button

Sat, 24 Jan 2026 23:51:13 +0100

Wen Lambo?

In the crypto world, nobody asks “When Coffee?”. They ask “When Lambo?” (or “Wen Lambo?” if you’re deep in the meme culture). This simple observation sparked an idea: why not swap the familiar “Buy Me a Coffee” aesthetic for something more fitting to the crypto generation?

My General AI Instructions

Sun, 18 Jan 2026 16:00:00 +0100

Awakening

Over the last six months, I have become completely hooked with AI and /different AI tools in general. I find myself discovering new use cases almost daily, and the pace of development is honestly staggering.

Recently, I’ve shifted heavily toward using Google Gemini. The functionality is just broader right now, specifically features like NotebookLM and its deep integrations with the Google ecosystem.

The “Bait and Switch” Cycle

However, it’s not all perfect. I’ve noticed a frustrating trend that seems to plague the AI industry. When a new model drops (like the initial excitement around the latest Gemini releases), it feels incredibly smart, fast, and capable. But as time goes on, it feels like they turn down the “intelligence” dial and tighten the soft blocks on usage limits.

Setting Up Ansible for Legacy Python Environments

Setting Up Ansible for Legacy Python Environments

Introduction

Last week, I learned a new fix for managing legacy Python environments with Ansible. This guide walks you through setting up an environment where you can use Ansible 2.10, which supports Python 2.7, using a tool called uv.

Step-by-Step Setup

1. Install uv

uv is a faster alternative to pip, designed for creating Python virtual environments. To install uv, you can use the following command:

Checkmk Downtime

Managing Downtime with Ansible and Checkmk

Ansible, combined with the tribe29.checkmk module, can automate the process of setting downtime in Checkmk monitoring. This article will guide you through installing the module, setting up your inventory, and writing and executing playbooks for scheduling and removing downtime.

Installation

First, you need to install the Checkmk collection for Ansible:

ansible-galaxy collection install tribe29.checkmk

Documentation

To understand how to use the module, you can check its documentation:
