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.

Unison File Synchronizer
If you look at the release notes you can see that some versions say they are protocol compatible with prior X.Y version release

Ask HN: Best modern file transfer/synchronization protocol?
I highly recommend Unison (https://github.com/bcpierce00/unison)
It allows you to sync between 2 machines (bi-directional) over TCP or SSH.
Note that TCP way is not encrypted, you may use wireguard as transport layer encryption for that purpose...
You can use an external application to copy if file size is larger than an arbitrary number. (Eg: use rsync for files > 1gb)

Google Drive + Obsidian + Linux?
The iOS app only syncs via iCloud or Obsidian Sync. I was in a similar situation (wanted to sync to Linux PCs and iPhone without paying for Sync), but I do have one always on Mac, so I set up a script that runs every minute, syncing my vault on iCloud with an identical vault on Synology Drive. My script basically just runs Unison once every few minutes to keep the two vaults in sync.

how can i sync 2 folders? between 2 machines
Unison is another alternative. I use it to synchronize my music with a Samba share and an usb stick, works great.
- How can I run rsync for two directories when files in either directory changes with a CLI, and without an infinite loop?
-
Are there any CLIs or good ways on macOS to real-time / continuously sync two folders on the same drive?
Unison
- Is there a way to automatically sync files between Linux computers (like Dropbox), perhaps with something like rsync?

Darke Files is a version control and file synchronization system
I've tested many file synchronization. I rely via scripts on Unison, originally authored by the computer scientist Benjamin Pierce, and now decades of tweaking by a strong open source community.
https://github.com/bcpierce00/unison
I'd love to see Darke Files get everything right that Unison gets right, that nearly all commercial projects get wrong, through a blend of arrogance and ignorance:
* Meta data. It takes a lot to insure that two copies of a MacOS file appear identical to a user. There used to be a test suite on the web that embarrassed everybody.
* Atomic folders such as ".git" or an application bundle. A prototypical example is a MacOS disk image, supported by a folder of many small files. This helps minimize incremental backup and transfer. Unison lets you specify the conflict resolution at the folder level, all-or-nothing decide which copy or fix it.
* Symbolic links. This is wildly complicated by users, sure they're right, who want special handling to hack features into sync software that isn't there. A symbolic link is just a file, with correct use the responsibility of the user. You wouldn't want sync software stopping to view your porn, right? They're just files, not the sync software's business.
I use Dropbox for various purposes because I need to, but they bungle more of this than one would expect. For example, a typical MacOS application bundle can have internal symbolic links a typical user never notices, pointing the "current" version of resources to a versioned folder. Last I checked, Dropbox expands the symbolic link into a redundant copy, wasting space without kneecapping the app.
One could go on...

Why Mathematical Proof Is a Social Compact
To be ruthlessly, uselessly pedantic - after all, we're mathematicians - there's reasonable definitions of "academic" where logical unsoundness is still academic if it never interfered with the reasoning behind any proofs of interest ;)
But: so long as we're accepting that unsoundness in your checker or its underlying theory are intrinsically deal breakers, there's definitely a long history of this, perhaps more somewhat more relevant than the HM example, since no proof checkers of note, AFAIK, have incorporated mutation into their type theory.
For one thing, the implementation can very easily have bugs. Coq itself certainly has had soundness bugs occasionally [0]. I'm sure Agda, Lean, Idris, etc. have too, but I've followed them less closely.
But even the underlying mathematics have been tricky. Girard's Paradox broke Martin-Löf's type theory, which is why in these dependently typed proof assistants you have to deal with the bizarre "Tower of Universes"; and Girard's Paradox is an analogue of Russell's Paradox which broke more naive set theories. And then Russell himself and his system of universal mathematics was very famously struck down by Gödel.
But we've definitely gotten it right this time...

In Which I Claim Rich Hickey Is Wrong
Dafny and Whiley are two examples with explicit verification support. Idris and other dependently typed languages should all be rich enough to express the required predicate but might not necessarily be able to accept a reasonable implementation as proof. Isabelle, Lean, Coq, and other theorem provers definitely can express the capability but aren't going to churn out much in the way of executable programs; they're more useful to guide an implementation in a more practical functional language but then the proof is separated from the implementation, and you could also use tools like TLA+.

If given a list of properties/definitions and relationship between them, could a machine come up with (mostly senseless, but) true implications?
Still, there are many useful tools based on these ideas, used by programmers and mathematicians alike. What you describe sounds rather like Datalog (e.g. Soufflé Datalog), where you supply some rules and an initial fact, and the system repeatedly expands out the set of facts until nothing new can be derived. (This has to be finite, if you want to get anywhere.) In Prolog (e.g. SWI Prolog) you also supply a set of rules and facts, but instead of a fact as your starting point, you give a query containing some unknown variables, and the system tries to find an assignment of the variables that proves the query. And finally there is a rich array of theorem provers and proof assistants such as Agda, Coq, Lean, and Twelf, which can all be used to help check your reasoning or explore new ideas.

Functional Programming in Coq

Basic SAT model of x86 instructions using Z3, autogenerated from Intel docs
This type of thing can help you formally verify code.
So, if your proof is correct, and your description of the (language/CPU) is correct, you can prove the code does what you think it does.
Formal proof systems are still growing up, though, and they are still pretty hard to use. See Coq for an introduction: https://coq.inria.fr/

What are the current hot topics in type theory and static analysis?
Most of the proof assistants out there: Lean, Coq, Dafny, Isabelle, F*, Idris 2, and Agda. And the main concepts are dependent types, Homotopy Type Theory AKA HoTT, and Category Theory. Warning: HoTT and Category Theory are really dense, you're going to really need to research them.
