CarolR

The aim of CarolR is to play synchronised, real-time, polyphonic music from an orchestra of devices in the same area, to create an immersive, collaborative, Christmas music experience.

Challenges

In the design of such a system, we had several challenges to overcome:

• Live performance music output
• Encoding and programming of synchronised, muti-track music

My method for storing and backing up photos is as follows:

1. All photos get downloaded into the Archive folder, in a folder for the current year, with the batch folder name starting with the date.
2. The photos get reviewed, the ones which get picked are edited, exported as JPEGs, and the edit metadata saved alongside.
3. Once editing is complete, the processed JPEGs are uploaded to wherever they're being shared (e.g. Google Photos).
4. Run the script below which copies only files which have been picked and edited into the Best folder using the same folder names, but not grouped into years.
5. The Best folder is backed up to a second local disk, and an offsite location (AWS Glacier).
6. The Archive folder is only backed up onto a second local replicated disk.
