Back-end Developer
Back-end DeveloperContributions:3 releases, 3 reviews, 521 commits in 10 years 9 months
Contributions summary:Jon primarily focused on refactoring and improving the command-line arguments parser in the Redshift application. They replaced the existing argument parsing with `getopt()` and added the ability to customize gamma correction and control the color temperature transition period. The user also added support for automatic location updates through the geoclue2 provider and refined the system to allow the program to be more easily controlled through command-line arguments and configuration files.
