gh-https

Converts a clone's GitHub remotes from SSH to HTTPS, for working from locations where SSH to github.com is blocked.

Install

echo '. /home/danclark/workspace/git-research/profile.d/gh-https.sh' >> ~/.bashrc

ddrescue — practical reference

GNU ddrescue copies data from a failing block device to an image file, keeping a mapfile of which sectors succeeded. That mapfile is what separates it from dd: every run is resumable, and you can make multiple passes with different strategies without re-reading sectors you already have.

Use it whenever the source is physically unreliable — failing HDDs/SSDs, scratched optical media, flaky USB sticks, SD cards. For a healthy disk, plain dd is fine.

DoD CAC / PKI Certificate Setup on Fedora

Prerequisites

Install the smart card and certificate management packages:

sudo dnf install opensc pcsc-lite pcsc-lite-ccid nss-tools p11-kit p11-kit-trust

Installing Citrix Workspace App on Fedora 43

This documents the process used to install Citrix Workspace App 26.04.10 on Fedora 43 (Linux 7.1.3-100.fc43.x86_64) with CAC smart card authentication support.

The Problem

The official Citrix Workspace App RPM (ICAClient-rhel-gcc-8-26.04.10.1-0.x86_64.rpm) fails to install via dnf because it depends on webkit2gtk3 >= 2.26, which provides libwebkit2gtk-4.0.so.37. Fedora 43 ships webkit2gtk4.1 (the 4.1 API) and webkitgtk6.0, but has dropped the older 4.0 API entirely.

This is a known issue. The webkit2gtk-4.0 library is only needed by the selfservice GUI (the graphical Citrix store browser). The core ICA session engine (wfica) and all session-related binaries do not depend on it and work fine without it.

LinqConnect Transaction Downloader

Download transaction history from LinqConnect (school meal accounts) and save it as JSON or CSV for import into Google Sheets or other tools.

Prerequisites

Python 3.10+
Playwright (only needed for browser login mode)

iPhone USB Tethering Setup for Fedora

How it works

iPhone USB tethering uses the ipheth kernel module to create a virtual ethernet interface. The usbmuxd daemon handles the initial USB multiplexing protocol but is not involved in the tethering data path itself — tethering uses a dedicated USB interface as a virtual network device.

usbmuxd is started automatically by udev rules when an iPhone is plugged in

notes-to-notebook

Find Gemini meeting notes in Google Drive, move them to a specified folder, and add them as sources to a NotebookLM notebook.

When Gemini takes notes during a Google Meet, it creates a Google Doc named after the meeting subject (e.g. "Team-A Weekly Team Sync - 2025-08-21"). This script finds those docs, moves them out of the default Google Meet folder into a folder you choose, and adds each one as a source in NotebookLM.
