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.
benchmark
- How can I check the execution time of a program rendered in SFML?
- How to Perf profile functions?
-
how do you properly benchmark?
I'm aware of one by Google that I used a couple times, but IMO it's better to capture real runtime data from a fully-operational process than to carve out the benchmarkable bits and test them in isolation, so I track information during program testing and print it all to a log instead of using things like that.

Benchmarking my data structure
If you just want to do some quick benchmarks, you can just use std::chrono::high_resolution_clock::now(). Call it before the code that you are benchmarking and then immediately after. Take them away and you have your duration. If you want to use a proper benchmarking tool then I can totally recommend Google Benchmark. Fantastic benchmarking tool. Honourable mention would be Quick Bench which is an online tool that uses Google Benchmark.

Google benchmark : No rule to make Target***
I tried to install google benchmark(https://github.com/google/benchmark) in my ubuntu machine by :

Don’t Be Scared Of Functional Programming
We don't know if it's a lie until we verify it and that's not difficult, you have a quicksort implementation in a couple of languages, you'll need to pass the necessary parameters to show the time needed by a function call to execute to the compiler or interpreter or you may use use a library(like benchmark for C++) and you're good to go.

How to identify inefficient method calls?
If you are uncertain about the performance characteristics of a function you should ALWAYS benchmark it. Googles Benchmark library is wonderful for quick micro benchmarks. For more complex things, perhaps look into profiling and then look at invocation counts of copy constructors.
-
Is there any fast allocator in std lib / boost for fixed size objects (not at compile time) but has deallocation methods?
Your compiler may be optimising away your loop, there. I typically use a micro-benchmarking tool for these types of tests. You could try Google Benchmark. It’s available in most OS’ package managers, but pretty easy to build from source if not

Calculate Your Code Performance
C++: C++ has quite a number of benchmarking libraries some of the recent ones involving C++ 20's flexibility. The most notable being Google Bench and UT. C does not have many specific benchmarking libraries, but you can easily integrate C code with C++ benchmarking libraries in order to test the performance of your C code.
Kalman

Starting out with Kalman Filter.
Since you mentioned C++ and Kalman filters, I author this Kalman filter library which helped me to get reacquainted to control theory, tries to be approachable, and lists a variety of sources to ease in the topic with examples.
-
How do you setup coverage/ sanitizers in your CI system.
Yes, and here's one for sanitizers. Other tools, documentation, and coverage in the neigbhorong files.

Trying to use FetchContent to include XercesC
I've been learning FectContent as well with some successes and failures.

kalman filter & c++
My goal with this Kalman filter for C++ is to solve your exact question.

C++ Show and Tell - December 2022
I released a first version of a generic Kalman filter.
-
Why is it that package managers are unnecessarily hard?
I use fmt and others in my project with CMake fetch and it's been a good experience so far: fetch, declare, link in a few lines. Hope this can be useful to someome.

Workflow v0.10.3 Released, Add WFRepeaterTask for Repeating Asynchronous Operations and Other New Features.
Gratuitous French codebase self-promotion though. /s

The Mathematics of the Kalman Filter
Would you be open to exploring an implementation collaboration? I author a C++ Kalman library and would like to expand demonstrators.
-
Does anyone know when gcc will support std::format?
A façade (example) included only for your GCC builds and with the fmt library would allow you to generically use the std::format support in your code. Avoiding the fmt:: and dependencies with MSVC. When the support lands in GCC, only that file would need to be deleted.
-
Best accurate way to measure/compare elapsed time in C++
I use it with boilerplate similar to this: https://github.com/FrancoisCarouge/Kalman/blob/develop/benchmark/benchmark.cpp and run the executables with priority and pining: nice -n 20 tasker -- cpu-list 0
