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.

is it ok to put library source code folder in your project folder to build them together?
Example from one of my projects: https://github.com/jgaa/nsblast/blob/main/cmake/3rdparty.cmake

REST APIs using C++. (Is this even done much?)
Yahat-cpp: Simple HTTP/API server library for use in C++ micro-services. This was just some code that kept evolving inside various projects, so I distilled it to a separate project to make it simpler to maintain. For an example of a real server using it, you cal look at nsblast, a new DNS server I'm implementing.

Has anyone embedded a web-UI into a C++ project?
I hope this question is not too off-topic here. I'm a bit lost. I'm working on a C++ project (a DNS server). It exposes a REST API via an embedded, very simple HTTP server. I have added swagger to document the API, and to test it from a browser. Now, I want to provide a simple web-UI to the application. I don't want this to become a major task, and ideally I want either a UI that lives as some simple js/css/http files in the browser, (so it can be served as a static website on the server-side like swagger) - or some simple to use back-end library in C++ that can drive the web-UI. In short, I hope to find a way to do this where I can have a POC ready in <= a week, and where I don't have to spend lot's of time learning some js framework.

Ask HN: Who is using C++ as the main language for new project?
I'm using C++ for most of my projects, because I like it. It's also what I do for a living. The latest new open source project I initiated is a dns server, nsblast, using rocksdb for storage. https://github.com/jgaa/nsblast
The (side) project I have put most effort into in the last year is k8deployer, a helm like utility that can deploy simple and complex applications in kubernetes with minimal effort. https://github.com/jgaa/k8deployer
In these projects I don't use other languages. C++ is the only language where I easily get into "flow".

Why Python's Integer Division Floors (2010)
This is because 0.1 is in actuality the floating point value value 0.1000000000000000055511151231257827021181583404541015625, and thus 1 divided by it is ever so slightly smaller than 10. Nevertheless, fpround(1 / fpround(1 / 10)) = 10 exactly.
I found out about this recently because in Polars I defined a // b for floats to be (a / b).floor(), which does return 10 for this computation. Since Python's correctly-rounded division is rather expensive, I chose to stick to this (more context: https://github.com/pola-rs/polars/issues/14596#issuecomment-...).

Stuff I Learned during Hanukkah of Data 2023
That turned out to be related to pola-rs/polars#11912, and this linked comment provided a deceptively simple solution - use PARSE_DECLTYPES when creating the connection:
- Polars 0.20 Released
- Segunda linguagem
- Polars: Dataframes powered by a multithreaded query engine, written in Rust
- Summing columns in remote Parquet files using DuckDB
- Polars 0.34 is released. (A query engine focussing on DataFrame front ends)
