Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I use hashdeep. You have to install ipkgui on Synology and then md5deep through that which includes hashdeep (or just use md5deep). You can read up on hashdeep/md5deep here in the docs folder: https://github.com/jessek/hashdeep/

How do I manage years of data?
Started to be able to bring some order after I discovered hashdeep. Basically I started from a reasonably clean disk with folders to sort files, created lists of hashes using hashdeep, then used it to scan all my existing disks for unknown files. With the correct flags hashdeep can list all files it finds on a disk that it has not in its lists already. That help a lot to figure out what is worth wasting time on. It also is useful because every now and then that makes me realize the copy of some old file I have is broken (probably usually because it was stored on some CDROM that was no longer good).

What are some alternatives?
winshatag - Detect silent data corruption on Windows using checksums in NTFS alternate data streams.
AntiDupl - A program to search similar and defect pictures on the disk
scorch - Silent CORruption CHecker and filesystem audit tool
snapraid - A backup program for disk arrays. It stores parity information of your data and it recovers from up to six disk failures
Rsnapshot - a tool for backing up your data using rsync (if you want to get help, use https://lists.sourceforge.net/lists/listinfo/rsnapshot-discuss)
RHash - Great utility for computing hash sums
BorgBackup - Deduplicating archiver with compression and authenticated encryption.
k4dirstat - K4DirStat (KDE Directory Statistics) is a small utility program that sums up disk usage for directory trees, very much like the Unix 'du' command. It displays the disk space used up by a directory tree, both numerically and graphically (copied from the Debian package description).
quickhash - Graphical cross platform data hashing tool for Linux, Windows and Mac
rsync - An open source utility that provides fast incremental file transfer. It also has useful features for backup and restore operations among many other use cases.
rclone - "rsync for cloud storage" - Google Drive, S3, Dropbox, Backblaze B2, One Drive, Swift, Hubic, Wasabi, Google Cloud Storage, Azure Blob, Azure Files, Yandex Files
