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 […]

Restic (backup) deleting old backups is extremely slow

Here’s a very quick note: I’ve been using the Restic backup tool with the SFTP backend for a while now, and so far it was great. Until I tried to prune some old backups. It takes two hours to prune 1 GiB of data from a 15 GiB backup. During that time, you cannot create […]

Lurch: a unixy launcher and auto-typer

Auto-type into currently focussed window Auto-type TOTP / rfc6238 / two-factor / Google Authenticator codes. Unixy and composable. Reads entries from stdin.

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:

Umatrix makes the web usable again

As happens with all media, once corporations join in because there is money to be made, things quickly devolve into a flaming heap of shit. The internet is no exception to this rule. With the coming of Javascript and DHTML in the late 90’s, ads soon started appearing on the web. Not long after, pop-ups […]

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 […]

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, […]
