Collection of custom scripts that I use in my Arch Linux work environment.

Table of Contents

ranwall

• Uses feh to change desktop wallpaper to a randomly chosen image

ranwall_time

• Meant to be run as a daemon
• Uses the aforementioned ranwall script to automatically change desktop wallpaper at a given interval (minutes)
• Outputs any given errors to notification center

ucvpn

• Uses openconnect to connect to the University of Chicago VPN network with the given username and password
• Sends success/failure messages to notification center

unzip_dir

• unzip to directory of same name as archive
• Really just a convenience script; no unique/complicated logic

timec

• Library of Python functions focused around automating:
  • The compilation of C source code and
  • The collection of a large sample size of execution times of the resulting executable
• Was written to facilitate data collection for my final project for CMSC 22200 Computer Architecture
• When executed by itself, returns mean and standard deviation information regarding execution time sampling of the program

timec_stats

• Python script that:
  • Compiles C source code,
  • Executes the resulting executable a user-specified number of times, recording the execution time of each trial,
  • Outputs relevant metrics (mean, standard deviation, and a fancy Normal plot of the resulting distribution), and finally
  • "Garbage collects" (by which I really mean it just deletes the executable)
• Was written to facilitate data collection for my final project for CMSC 22200 Computer Architecture
• Uses the functions from timec
• Work in progress. The implementation is still very hacky and tied into the specific needs of my project at the time; it uses a multitude of hard-coded values that probably would render this script unuseable outside of my directory tree. As such, I would not recommend using this right now. Of course, feel free to take it and modify it to suit your needs; sharing is caring.
