System Quirks & Tweaks

System Info:-

CPU: 16-core AMD Ryzen 9 3950X (-MT MCP-) speed/min/max: 2433/2200/4761 MHz

Kernel: 6.8.0-134-generic x86_64 Up: 18h 28m Mem: 17.58/62.73 GiB (28.0%)

Storage: 3.64 TiB (81.9% used) Procs: 616 Shell: Bash inxi: 3.3.34

Some of the hacks:-

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.

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.

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.
KWin Layout Fixes: Joplin is set to bypass the taskbar.

Weather & Brightness: Custom scripts feed my desktop panel with weather emojis from the 7Timer! API and let me change external monitor brightness using ddcutil over I2C.
Notification Pipelines: Custom shell scripts polled for SMS and email alerts, using MD5 hashes of the text blocks to ensure I never got duplicate notifications.
Fake GPS Server: A tiny local server on port 22222 returns my home coordinates to any local app requesting geolocation.

Hardware Recycling: An old Android tablet with a broken screen is used as a green-screen terminal. It runs a custom WebView app to display ambient data.
Gmail Push Pipeline: A local PHP script runs via cron every 10 minutes to fetch new email alerts and send them to the tablet over the local network.
