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.

- Common Rust Lifetime Misconceptions
-
What are some good resources for experienced programmers new to Rust to learn about lifetimes?
Hands down the best resource (after you've had sufficient experience with Rust, especially so) - https://github.com/pretzelhammer/rust-blog/blob/master/posts/common-rust-lifetime-misconceptions.md
-
How can a parameter type `T` be not long living enough?
I really really recommend reading this to understand lifetimes and generics in Rust better.
- What learning resource has had the greatest impact in elevating your understanding and knowledge of Rust?
- I do not understand why Sized bound prevents a trait from being used as a trait object.
-
Lifetime annotations: why doesn't Rust?
It's already now that the elided lifetimes are not always correct, as pointed out in Common Rust Lifetime Misconceptions (No 5) by pretzelhammer.

Resources on Lifetimes
Probably a bit more advanced than what you asked about, but still possibly useful: Common Rust Lifetime Misconceptions by /u/pretzelhammer.

Borrow checker puzzles
This helped me a lot understanding Rust ownership rules and lifetimes: https://github.com/pretzelhammer/rust-blog/blob/master/posts/common-rust-lifetime-misconceptions.md

We build X.509 chains so you don't have to
Congratulations to the authors, this was a feature that was dearly missing from pyca/cryptography. It took a long time to get right.
For the history: https://github.com/pyca/cryptography/issues/2381

“Our paying customers need X, when will you fix it?”
Some context:
- The cryptography dependency used by the current release of mitmproxy has a CVE related to an OpenSSL vulnerability (https://github.com/pyca/cryptography/security/advisories/GHS...)
- The main branch of mitmproxy has already upgraded to the latest version of the cryptography package
- The author of the package does not believe the CVE impacts users of mitmproxy so a release including this commit has not been made

Microservice memory profiling
first, I did see a correlation between an endpoint being heavily hit in a given time window, and an increase of memory usage that didn't went down afterwards. The endpoint didn't do much so I went through every instruction - is a global variable appended indefinitely ? Is a cache decorator growing without a limit set ? Do I use a 3rd party that has a known issue ? Turns out, it was using cryptography, so I looked up known issues. Saw an issue about a leak when using load_pem_x509_certificate https://github.com/pyca/cryptography/issues/4833 - which I used ! I could fortunately just upgrade the library

[Python] Poésie vs Pipenv vs. pip-tools: Qu’utilisez-vous?
Après le kerfuffle du paquet de cryptographie cette semaine (https://github.com/pyca/cryptography/issues/5771), J’ai passé en revue l’état des outils de gestion des dépendances en Python.

I love building a startup in Rust. I wouldn't pick it again
> A big problem with Rust, long-term, is that the kind of programs that really need it are somewhat out of today's mainstream. It's not that useful for webcrap. It's not that useful for phone apps. The AI people use Jupyter notebooks and Python to drive code on GPUs.
One thing this is missing is that Rust is useful for libraries callable by many different languages. You may or may not want to use it to build an actual Web app (I personally think it's a solid choice, but reasonable people can disagree). But for building, say, the Python cryptography library [1], which is used as a part of "webcrap" and Jupyter notebooks, Rust is clearly an excellent option. Nobody is going to build core Python infrastructure in Go or Node, and there will always be a need for plumbing libraries.

The impossible case of pitching rust in a web dev shop
Also, I see more and more examples where rust gets included in different technologies using FFI. Ie for python https://github.com/pyca/cryptography for security/performance critical pieces.

os independent way to convert ssl crt to pem
You will be hard pressed to find a cryptography library that doesn't depend on openssl. Fortunately openssl bindings can be installed on Windows. One of the more popular libraries for python is cryptography, but it does depend on libssl.
