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 to define API stability for a C++ library?
https://github.com/ned14/outcome/tree/develop/abi-compliance uses both in a CI pass to ensure Outcome never changes anything which breaks either API or ABI with earlier versions.
-
What are some cool modern libraries you enjoy using?
outcome and/or expected
-
Outcome enters sustaining phase, goes ABI stable
A "Sample Usage" appears on the front page of the docs: https://ned14.github.io/outcome/

Does Anyone Use Boost Outcome?
I recently came across boost outcome as I was searching for a better error handling method. It took me a minute to get a hang of it but now I love it. After creating my own policy and a few aliases for easier use.
-
Is this error handling strategy good?
std::optional and std::variant can be a bit awkward to use in this scenario, though. Consider a dedicated type like boost::outcome (standalone versions) or one of the implementations of the proposed std::expected.

Modern C++ "result" type based on Swift / Rust
Minimum possible compile time impact is a key goal of https://github.com/ned14/outcome. We ship a single header edition which only includes the low impact standard headers as listed at https://github.com/ned14/stl-header-heft. We also don't use union storage for non-TC non-MB types in order to avoid complex metaprogramming execution by the compiler per instantiation.

C++ Memory Safety
It's really weird that I wrote the above, and then this bug was reported to Outcome: https://github.com/ned14/outcome/issues/244. Here is my exact complaint about lack of lifetime tracking in C++.

Parsing time stamps faster with SIMD instructions
It's not bad at all https://github.com/lemire/Code-used-on-Daniel-Lemire-s-blog/...

Under Linux, libSegFault and addr2line are underrated
A newline is missing in the example code. As given there's a segfault at line 5 not line 6.
However, the code at https://github.com/lemire/Code-used-on-Daniel-Lemire-s-blog/... shows it's indeed at line 6, because it has an extra newline after the '#include '.

Technical Blogs You Recommend?
Dr. Daniel Lemire's blog: https://lemire.me/blog, covers lots of technical items on optimizations in various programming languages, Lemire's work is currently in use across a number of projects and he consistently delivers fantastic improvements, he usually accompanies these improvements with a blog post describing what he did. He also occasionally posts interesting Science and Technology links on various topics not limited to tech, but health and education as well.
- suggest some c language blogs....

Nope, simdjson is originally from Daniel Lemire who also often blogs about fancy low level optimizations: https://lemire.me/blog/ I'm just a happy user :)

Escaping strings faster with AVX-512
Added this pull request with some interesting results.
There's a copy of the loop used on the escape function inside the avx512_escape function [0]. Is it needed or just a copy and paste mistake? (I know nothing about vector instructions)
