Fixing Invalid Format SSH Key Errors in ChromeOS Secure Shell
Published:
Fixed an invalid format error when importing SSH keys into ChromeOS Secure Shell by addressing missing newline characters and cipher issues.
Running code-server on a remote workstation, bound to my VPN
Published:
I bought a cheap Chromebook on a whim and quickly realized VS Code’s desktop app isn’t something you want to run on a dual-core Celeron with 4GB of RAM.
Exposing an SSH Server on a Non-Tailscale Machine via Tailscale Serve
Published:
I needed to SSH into a shared office server that can’t run Tailscale, so I bridged it through a nearby workstation using Tailscale Services and a TCP forwarder.
Getting Tailscale’s ethtool offload tweak to persist on Fedora uCore
Published:
Tailscale’s UDP GRO forwarding docs assume networkd-dispatcher, but ostree-based systems like Fedora uCore run NetworkManager instead. Here’s what works.
KDE Plasma: Manual Screen Off Button
Published:
I needed to power off my laptop screen on demand without pausing background tasks. Here’s a quick guide to a menu item that puts the display straight to standby.
A small Glance setup with Podman, feeds, and Tailscale. A personal feed!
Published:
I wanted a lightweight, self-hosted dashboard for news, research, and YouTube feeds without the bloat. Glance fits the bill, deployed on a spare Raspberry Pi.
Disable Wifi powersave mode in my laptop (old, seems to be fixed)
Published:
Wi-Fi power-save mode on my Fedora ThinkPad causes latency, jitter, and packet loss on Tailscale and VoIP, plus connection drops after suspend. Here’s the fix.
Trivia Dataset & Tooling Links
Published:
The other day I was interested on creating a big list of trivia questions to play with my friends. I surfed the internet and found these!
The Ultimate List of Free Browser Party Games (No Download Needed)
Published:
A running collection of browser-based, mostly-free party games for group game night: no installs, just send a link in Discord or Zoom and go.
VSCodium Flatpak: Trash + KWallet fixes
Published:
Flatpak sandboxing breaks VSCodium on Fedora Kinoite: trashbin doesn’t work, and it can’t reach KWallet, leaving GitHub tokens stored in plain text.
GitHub multi-account in VSCode
Published:
VS Code doesn’t handle multiple GitHub accounts well. Here’s how to set up separate profiles for work vs. personal accounts using --user-data-dir and KDE launchers.
uCore Bare-Metal install (Butane, Podman, Tailscale)
Published:
uCore is Fedora CoreOS with homelab defaults baked in by Universal Blue: declared upfront in Butane, transpiled to Ignition, consumed once at boot.
Reorder firefox/librewolf profiles in the profile manaer window
Published:
Firefox and LibreWolf let you create separate profiles for work, personal, and gaming logins, but there’s no built-in GUI way to reorder them once created.
Local AI: Ollama + Open WebUI (old)
Published:
A local, private AI setup: Ollama plus Open WebUI, running rootless via Podman Quadlets/systemd. Works well on atomic desktops like Fedora and Bluefin.
Installing Microsoft fonts on a linux desktop distro (no root)
Published:
Time ago I left behind Windows and replaced it with a Linux distro. Of course, they don’t come with the Windows fonts. Easiest fix: drop the fonts into your user directory.
Firefox/librewolf profile manager at start
Published:
Firefox/LibreWolf offers two ways to manage profiles. The classic selector GUI lets me choose which profile opens a link, or reject it on a misclick.
M575 Trackball: Scroll with the trackball instead of the wheel in KDE
Published:
I prefer thumb trackballs with scroll-via-ball, which worked on Windows via AutoHotkey but not Linux, until I found KDE’s built-in implementation.
KDE Plasma: Manual Screen Off Button
Published:
I needed to power off my laptop screen on demand without pausing background tasks. Here’s a quick guide to a menu item that puts the display straight to standby.
Enabling Firefox’s containers
Published:
For some reason, in my Firefox’s installations of my Linux machines the containers function is just not enabled and can’t find it in the settings. This includes Librewolf browser as well. It its very simple to activate.
Filtering clipboard data before pasting into LLMs
Published:
A way to “filter” your clipboard before pasting into an LLM chatbot, using KDE’s clipboard actions to strip names, IPs, emails, and other details.
