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.

How do you protect yourself from failing drives and data corruption?
Calculate their digests with rhash or similar utilities (but not too frequently, or you'll beat up your hard drives! once a month is plenty).
- Forever version history has potential, this is an opportunity for BB
- How do I use these commands for a mac torrent? I'm not super Terminal literate.

External drives content index solution
Yeah, I ran across two programs that did this: https://github.com/rdiez/Tools/tree/master/RDChecksum Uses file existence, file size, and modified date to add/remove/rehash a file in the list. https://github.com/rhash/RHash Uses only file existence So both of these store relative file path/name with the hash to see if a given file is new/deleted, and RDChecksum additionally will rehash existing files if they've been modified. Personally I feel like just the existence of the file would be enough if you could also tell it to rehash just as specific sub-directory from a larger checksum file that you know has been updated

went back to watch an old video, just to find out it was corrupted midway. previous backup must have overwritten it...is there any program that can scan for corrupted movie files or means to compare before overwriting?

Crypto Resources
RHash is a great place to start. Easy-to-read cryptographic hash functions. Libsodium is your go-to though for cryptographically secure hash and encryption functions.

Libsodium: A modern, portable, easy to use crypto library
Libsodium has been around for a while, so probably the reason it was posted is that version 1.0.19 was just released: https://github.com/jedisct1/libsodium/releases/tag/1.0.19-RE...
Updated NuGet and Swift packages are going to be uploaded soon.
AEGIS-128X and 256X are not there yet, but if you need them, they are available in libaegis: https://github.com/jedisct1/libaegis
All the code from libaegis will eventually be merged into libsodium, including the incremental update API which is especially useful for TLS.
- Libsodium 1.0.19 Released
- FLaNK Stack Weekly for 20 June 2023

Libsodium Still Relevant and Maintained?
To version the dependency you can check the current stable tree in git and save the date and git hash.

I created an encrypted command line jounal
To address both of these vulnerabilities, you should instead use a library that handles these sharp edges for you. A well received library in the security and cryptography communities is libsodium. It has high level functions that handle password hashing and data encryption for you, reducing the risk that you introduce vulnerabilities in your code, such as you have here.

Why can't I burn scam tokens by sending them to 0x000000000000000000000000000000000000dEaD?
In general, cryptography is really hard. So for example, an attacker could construct a message that if you signed would leak information, ie it reduces the space of possible keys such that it can be brute forced. I’m not entirely sure if you could do that with a transfer function. But it’s certainly possible. That said, there are a ton of smart devs trying to prevent that as well so I’m not assuming anything here. But prudent practices are likely good to follow. Be very careful calling anything from your cold wallet etc. Use disposable keys for anything a bit risky. I took a sec to google an example and this is the closest I could find. https://github.com/jedisct1/libsodium/issues/170

Some questions from a noob Rustacean
Hi everyone! I'm learning Rust while on a break between jobs, and as I'm particularly interested in interfacing Rust with C and in cryptography, I've decided to write a wrapper around libsodium (https://github.com/jedisct1/libsodium) in Rust. This is purely a hobby project and I probably won't ever release it as there are already some open-source Rust bindings available for the library.
