I discovered a website with a beautiful world map that updates throughout the day to show sunlight and nighttime right now:
I thought it would make an excellent desktop wallpaper and wrote a script to pull the image every half hour and set it as the background image. That worked really well so I thought I’d share it, which led me to create a sweet little installer for it:
- Download this file,
- make it executable,
- and run it.
This will create a script that pulls the image from the Internet and sets your wallpaper. It will also add the script to yourÂ crontabÂ so it automatically runs once every half hour. Re-running the installer will replace the update script but it will not put another cron job in your crontab. I find that rather elegant!
It’s very simple for skilled people, but I consider myself fairly novice in Linux so I am proud enough of it to post this! I also took the opportunity to post my code publicly onÂ GithubÂ because I’ve heard it’s the thing to do. In the words of Karl Broman:
Github is like facebook for programmers. Everyoneâ€™s on there. You can look at what theyâ€™re working on and easily peruse their code and make suggestions or changes.
Itâ€™s really open source. â€œOpen sourceâ€ is not so open if you canâ€™t easily study it. With github, all of the code is easily inspected, as is its entire history.
This was fun!
