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.

Resources to learn secure coding? App Sec and Web Sec?
Here is a repo of some resources. You are going to need to learn to walk before you run so that at a concrete level you can articulate what secure vs insecure code is and why it matters, then dive into appsec. No disrespect intended but from the way this is written my suggestion would be to focus on computer science foundational concepts as well as spending significant time writing and reading code. This will likely be a several year journey if you are a total beginner but the best time to start is now :)

Anyone in AppSec (Application Security)?
Come over to /r/devsecops to get more information about the field. Also, there are lots of good sources, you can get some from my blog, or Awesome AppSec, or Security Prince and other places.
- I'm preparing for the interview and I've curated a list of resources that might be helpful for you also.

Heartbleed and XZ Backdoor Learnings: Open Source Infrastructure Can Be Improved Efficiently With Moderate Funding
Today, April 7th, 2024, marks the 10-year anniversary since CVE-2014-0160 was published. This security vulnerability known as "Heartbleed" was a flaw in the OpenSSL cryptography software, the most popular option to implement Transport Layer Security (TLS). In more layman's terms, if you type https:// in your browser address bar, chances are high that you are interacting with OpenSSL.

Ask HN: How does the xz backdoor replace RSA_public_decrypt?
At this point I pretty much understand the entire process on how the xz backdoor came to be: its execution stages, extraction from binary "test" files etc. But one thing puzzles me: how can the ifunc mechanism be used to replace something like RSA_public_decrypt? Granted this probably stems from my lack of understanding of ifunc, but I was under the impression that in order for the ifunc mechanism to work in your code, you have to explicitly mark specific function with multiple implementations with __attribute__ ((ifunc ("the_resolver_function"))). Looking at the source code of the RSA function in question, ifunc attribute isn't present:
https://github.com/openssl/openssl/blob/master/crypto/rsa/rsa_crpt.c#L51
So how does the backdoor actually replace the call? Does this means that the ifunc mechanism can be used to override pretty much anything on the system?

Use of HTTPS Resource Records
OpenSSL and Go crypt/tls has no support yet, so none of the webservers that depend on them support it. Apache, Nginx, and Caddy, they all need upstream ECH support first.

- https://github.com/openssl/openssl/pull/22938
- https://github.com/golang/go/issues/63369
- openssl-3.2.0 released
- Large performance degradation in OpenSSL 3
- OpenSSL 3.2 Alpha 2

Encrypted Client Hello – the last puzzle piece to privacy
If I'm understanding the draft correctly, I think the webserver you're hosting your sites on would need it implemented as it requires private keys and ECH configuration. In the example of nginx since it uses openssl, openssl would need to implement it. I found an issue on their Github but it's still open: https://github.com/openssl/openssl/issues/7482

OpenSSL Versions... whats the plan here
I confirmed that the systm was on 1.1.1f with openssl version command. Hmm...... I check the openssl version in the repo with apt list... LOL package names wernt helpful. finally went to the repo pages and found that its still on 1.1.1f, https://launchpad.net/ubuntu/+source/openssl. Meenwhile I looked up the version history on https://www.openssl.org/ and saw that 1.1.1v was released at the beginning of this month... ok. I can understand it it was out less then 30 days. I looked up when f came out, end of MARCH 2020. NEARLY 3-1/2 YEARS
