Some of the hacks:-

Shell & Terminal Setup

Visual Host Identifiers: I use custom terminal prompt colors and styles on different boxes so I can immediately see which machine I am logged into.

Command Line Overrides: Standard tools are aliased to modern alternatives ( cat to batcat , df to duf , du to dust , ls to eza ).

Word-Break Tweak: My shell config strips - and . from word-break rules so tab-completion handles hyphenated or dotted filenames as single words.

History Search: I mapped Ctrl+F (instead of Ctrl+R ) to run a custom, colorized, interactive fuzzy history search using fzf .

Local AI Tooling: I use AI coding interfaces, with ollama aliased to run Qwen Coder by default.

Complex Toolchains: My system runs multiple co-existing environments, including conflicting Java runtimes (8 and 17), Android SDK, Rust, Go, and local Perl/Python libraries.

Autostart & Background Services

Audio & RGB Tweaks: Custom services handle Bluetooth switching for my Bose QC35 headphones, and cycled my keyboard lighting profiles based on the time of day.

Passive Time Tracker: A custom background system tracks files via inotifywait and polls network connections to log my work hours into a 15-minute rounded log file.

Typo Alert Keylogger: A root-owned background script buffered my keystrokes globally to run a spellcheck, firing a desktop alert when I made a typo.

Work/Life Balance: Discord is configured to launch only on weekends or after 17:30 on weekdays.

Custom Applications & Launchers

Local LLM Voice Assistant: A desktop launcher opened "Marvin," a private local voice-chat assistant.

Custom Remote Control: A custom script used ADB and Monkeyrunner to mirror and control an Android tablet screen in a local window.
