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.

Converting my new code (Bytearray2Float64) into 19 Programming Language
In my previous dotnet pivot table web, I have implemented a in-memory data object serialized in disk. You can find the source code https://github.com/hkpeaks/peaks-framework/tree/main/PeaksDataFrameViewer

Need Golang Community to Support a Hyper-performance of DataFrame Library
My Peaks DataFrame project is aiming at billion-row level data processing (extract-transform-load) for csv/parquet/json/excel/html files with little memory (recommend 16GB or above, for billion rows processing, it is recommended using NVMe SSD harddisk).

How does sqrt() work in glibc?
I am writing a short paper for school and the topic is Fast Inverse Square Root and alternatives. One of the questions is how the sqrt-function is implemented in glibc. Here is the code of that function.

A collection of lock-free data structures written in standard C++11
The code isn't the easiest to read but in glibc it seems that the syscall is only performed if waiter are detected in userspace during an unlock operation

Converting my new code (Bytearray2Float64) into 19 Programming Language
You might still not realize, but floats are a large topic. Have a look at eg. this implementation here: https://github.com/lattera/glibc/blob/master/stdlib/strtod_l.c

Honest question about this "The byte order fallacy" blog post.
This is a nice write up, thank you. However, I'm stilling interpreting this as a "fun trick" rather than the common sense method for solving the problem. For example, looking at the source code for htonl() from glibc: https://github.com/lattera/glibc/blob/master/inet/htonl.c

Second of all: The horrifying truth is that there is no such thing as a canonical text representation for IPv4 (source) (and yes... I am indeed citing the failed attempt to standardize this as my source for it not being standardized). Authoritatively speaking, all possible (non-binary) representations are equally invalid. In fact, text address resolution is typically delegated to the OS kernel, so what constitutes a "usable" address is liable to vary depending on if you're using Linux, OSX, Windows, or Other.

Discussion Thread
Optimized code gets really weird. The creators of strlen, for example, decided that iterating over each character to find the end was far too slow. So instead, they convert the character pointer into an int pointer and do bitwise manipulation with the int on two different magic numbers so they can check four/eight characters at once.

How does jvm deal with syscalls
If you're using a cross-platform C compiler like gcc or clang, you're usually expected to switch to assembly. Here's the syscall instruction in glibc

Math Functions with -nostdlib
Maybe you should include the math part of a libc statically with your code. glibc is one option, or dietlibc if you want it to be as small as possible.
What are some alternatives?
