An Audio / Video profile switcher (and app launcher) script for Linux

Since the start of Corona, my company has been mostly working remote. That means more video conference meetings. A lot more. So much in fact, that I decided to automate the process of setting everything up correctly for that and other audio video profiles. For example, my webcam is in my laptop, whose screen I […]

Finding and removing packages installed from non-standard repos in Ubuntu

Update: Oh, look, right in the nick of time: “Valve Steam through 2021-04-10, when a Source engine game is installed, allows remote authenticated users to execute arbitrary code because of a buffer overflow that occurs for a Steam invite after one click” As part of my big spring cleaning, as well as given all the […]

sla: The Simple Little Automator

I’m tired of using Make and its arcane syntax. 90% of the projects I write or deal with don’t require any kind of incremental compilation, but that’s all any build system talks about. That, and how insanely fast it is. The drawback is usually that you need to install several terabytes of dependencies, and then […]

direnv: Directory-specific environments

Over the course of a single day I might work on a dozen different admin or development projects. In the morning I could be hacking on some Zabbix monitoring scripts, in the afternoon on auto-generated documentation and in the evening on a Python or C project. I try to keep my system clean and my projects […]

Multi-git-status now shows branches with no upstream

Just a quick update on Multi-git-status. It now also shows branches with no upstream. These are typically branches created locally that haven’t been configured to track a local or remote branch. Any changes in those branches are lost when the repo is removed from your machine. Additionally, multi-git-status now handles branches with slashes in them […]

Lurch: a unixy launcher and auto-typer

I cobbled together a unixy command / application launcher and auto-typer. I’ve dubbed it Lurch. Features: Fuzzy filtering as-you-type. Execute commands. Open new browser tabs. Auto-type into currently focussed window Auto-type TOTP / rfc6238 / two-factor / Google Authenticator codes. Unixy and composable. Reads entries from stdin. You can use and combine these features to […]

multi-git-status can now hide repos that don’t need attention

I’ve added an “-e” argument to my multi-git-status project. It hides repositories that have no unpushed, untracked or uncommitted changes. Without “-e”: And with the “-e” argument:

Root your Docker host in 10 seconds for fun and profit

Disclaimer: There is no actual profit. That was just one of those clickbaity things everybody seems to like so much these days. Also, it’s not really fun. Alright, on with the show! A common practice is to add users that need to run Docker containers on your host to the docker group. For example, an […]

sshbg: Change terminal background when SSHing (for Tilix and Xterm)

This is gonna be a short post. I wrote a tool to change the background color of my terminal when I ssh to a machine. It works on Tilix and Xterm, but not most other terminals because they don’t support the ANSI escape sequence for changing the background color. It works by combining SSH’s LocalCommand […]

Enable dnsmasq DNS query caching on Ubuntu 16.04

It appears that by default, DNS query caching is disabled in dnsmasq on Ubuntu 16.04. At least it is for my Xubuntu desktop. You can check if it’s disabled for you with the dig command: $ dig @127.0.1.1 ubuntu.com $ dig @127.0.1.1 ubuntu.com Yes, run it twice. Once to add the entry to the cache, […]
