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.

The Haskell job market has been growing steaily since 2008
We used reflex-frp, so our app was a webview that worked on localhost and Android. The docs say it also works on iOS but we don't have an iPhone.
The process was learning Functional Reactive Programming, then learning reflex-frp, then getting a contract with obsidian (creators of reflex) for one hour a week where we could ask questions.

We had a grant requirement to create a phone client for Tahoe-LAFS, a Python application with a bunch of dependencies, including ZFEC, a forward error correction library.
( https://tahoe-lafs.readthedocs.io/ )
( https://github.com/tahoe-lafs/zfec/ )
We needed bug for bug compatibility with the Python codebase, so I ran Tahoe on localhost and tested the Haskell client against the Python server. We used servant to build the API, since it builds both client and server side from the same description.

Xz format considered inadequate for long-term archiving
I disagree with the premise of the article. Archive formats are all inadequate for long-term resilience and making them adequate would be a violation of the “do one thing and do it right” principle.
To support resilience, you don’t need an alternative to xz, you need hashes and forward error correction. Specifically, compress your file using xz for high compression ratio, optionally encrypt it, then take a SHA-256 hash to be used for detecting errors, then generate parity files using PAR[1] or zfec[2] to correct errors.

Duplicity
I used this many, many years ago but switched to Borg[0] about five years ago. Duplicity required full backups with incremental deltas, which meant my backups ended up using too much disk space. Borg lets you prune older backups at will, because of chunk tracking and deduplication there is no such thing as an incremental backup.

What do you use for VPS backup? Would improved borg setup - pull mode - be enough? Or, do you use something else?
Currently, I'm auto-backing it up with borg (push mode) through wireguard tunnel to NAS behind ISP's CGNAT. The borg takes care of deduplication in SQL file, so incremental update (even in append-only mode) is very small for PostgreSQL dump.

Kopia: Open-Source, Fast and Secure Open-Source Backup Software
Borg 2 has been in development for nearly a year and a half [1] and may probably be released early next year, i.e., early 2024 (just a guess, seeing that even RC1 is not yet released and seems to have a lot of work to be done).
Does anyone know how Borg 1.x and 2 would compare to Kopia?

disc space is not freeing
You could use borgbackup.
- My deduplication solution written in Rust beats everything else: casync, borg...
What are some alternatives?
pixz - Parallel, indexed xz compressor
Duplicati - Store securely encrypted backups in the cloud!
zpaqlpy - Compiles a zpaqlpy source file (a Python-subset) to a ZPAQ configuration file for usage with zpaqd
Duplicity - Unnoficial fork of Duplicity - Bandwidth Efficient Encrypted Backup
reflex-platform - A curated package set and set of tools that let you build Haskell packages so they can run on a variety of platforms. reflex-platform is built on top of the nix package manager.
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)
fossa-action - The action sets up and caches the latest release of fossa-cli, infer the correct configuration from the current system state, analyze the project for a list of its dependencies, and upload the results to FOSSA.
restic - Fast, secure, efficient backup program
haskell-jobs-statistics
TimeShift - System restore tool for Linux. Creates filesystem snapshots using rsync+hardlinks, or BTRFS snapshots. Supports scheduled snapshots, multiple backup levels, and exclude filters. Snapshots can be restored while system is running or from Live CD/USB.
