This visualization documents a systemd service and shell script that work around a Linux kernel touchscreen bug on the Dell XPS 13 9350. The example shows how the script determines the correct GPIO pin by parsing `/sys/kernel/debug/pinctrl/INT344B:00/pins` with `awk` and reading the `gpio-ranges` file with `sed`, then exports the pin via `/sys/class/gpio/export`, sets its direction to `high`, and unexports it. It also includes a kernel-version check using `uname -r` that halts execution when the installed kernel differs from the patched version.

The visualization demonstrates a shell script that repairs a security flaw in the Pico-8 binary by removing a hardcoded RPATH pointing to `/usr/local/lib`, which is inappropriate for Arch Linux. It shows the `fix-rpath.sh` file using the `chrpath` command with the `--delete` flag to strip the insecure path. The example highlights a command-line data-processing task rather than graphical rendering, relying on the system's `chrpath` utility to inspect and modify ELF binary metadata. No JavaScript libraries or charting APIs are involved; the focus is on the script's logic and the specific tool invocation.

This example visualizes a system administration workflow that automatically masks or unmasksthe Linux sleep and suspend targets based on active SSH sessions. It shows a shell script that counts established SSH connections on port 22 using `ss` and `awk`, then conditionally runs `systemctl mask` or `systemctl unmask` on `sleep.target` and `suspend.target`. The visualization highlights the script’s branching logic driven by `PAM_TYPE` (open or close session) and the connection count. No external charting library is used; the code relies on standard shell utilities (`ss`, `awk`, `logger`, `sudo`) to manage systemd power management.

Disable touchpad on mouse detection on Ubuntu 14.04.04

This example shows a udev rules configuration that automatically disables the touchpad when an external mouse is connected and re-enables it when the mouse is removed. The code defines two rules in `/etc/udev/rules.d/01-touchpad.rules`, using the `SUBSYSTEM`, `KERNEL`, `ACTION`, and `RUN` parameters to trigger the `synclient` command on mouse add or remove events. It sets the `TouchpadOff` property to 1 or 0, and explicitly passes the `DISPLAY` and `XAUTHORITY` environment variables to ensure the command reaches the correct X session. The rules follow the Arch Linux wiki’s Touchpad Synaptics documentation.

My Linux Setup

This visualization documents a step-by-step Linux setup process, covering installation, customization, and development environment configuration. It uses a text-based layout with embedded screenshots and command-line code snippets to illustrate each stage. The guide references specific tools and libraries including Xubuntu, Docky, Numix Circle, zsh, oh-my-zsh, NVM, and Node.js, along with shell commands for package installation and theme configuration. The article presents the author’s personal technical stack as a static checklist, with the source data derived from a markdown file and the visual formatting handled by the gallery’s rendering system.

The visualization shows a terminal error message sequence for resolving a locked dpkg package manager lock in Ubuntu Linux, displayed as styled text output. It presents the error, the commands `sudo fuser -vki /var/lib/dpkg/lock`, `sudo rm -f /var/lib/dpkg/lock`, `sudo dpkg --configure -a`, and `sudo apt-get autoremove` as a troubleshooting flow. The rendering uses d3.js to bind the error and command strings to DOM elements, with d3 transitions animating the appearance of each line sequentially. The data is static text embedded directly in the code, with no external data source.

Gist da4df60b12f754d8da27f117f5bd7b7f

This example shows a shell script that retrieves the current display name via `xrandr` and then sets the screen brightness using the `xrandr --output` command with a specified brightness level. The code parses the monitor identifier by filtering the output of `xrandr | grep " connected"` and cutting the first field. It relies on the `xrandr` command-line tool, which is part of the X11 display management utilities, and references a tutorial for adjusting brightness from the terminal. No external libraries or data sources are involved.

Gist 28812206a0e39e26297e4424830da6be

This visualization documents the GPIO header layout of a Raspberry Pi-compatible board, presenting a labeled diagram alongside a technical table. The image identifies each pin’s physical position, electrical type (power, ground, I2C, UART, or general-purpose I/O), and its corresponding BCM numbering scheme. The table details each signal’s function, electrical level (5V, 3.3V logic, or ground), and usage notes, such as suitability for sensors or UART communication. The rendering uses a static schematic diagram with matched annotations, while the table is formatted in Markdown for clarity.

Working drives

This visualization maps the process of mounting and managing external drives on a Linux system, using a flowchart-style layout. It shows the sequence from identifying a drive (via `lsblk` or `sudo fdisk -l`) through creating a mount point, mounting the partition, and updating `/etc/fstab` for persistence, ending with optional symbolic links in `Documents`. The code uses D3.js (`d3.forceSimulation` or similar layout) to arrange nodes and links, with text labels for each terminal command and file path. Data comes from the author’s collected notes and cited tutorials, rendered as a directed graph where each step branches into sub-actions like `sudo chown` for permissions.
