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 scan QR Barcode with Windows 10 Webcam on laptop - Without using an emulator?
ZBar - ZBar is a widely used open-source software that supports scanning QR codes with a webcam on Windows 10. https://zbar.sourceforge.net/

Is there an open source QR code reader for Windows?
I'm pretty sure ZBar is supported on windows. It includes the zbarcam tool, which can scan from camera.

How to decode a QR-code image in (preferably pure) Python?
ZBar (website here) claims to be "an open source software suite for reading bar codes from various sources, such as image files." So I tried installing it on Mac OSX running sudo pip install zbar. This fails with error: command 'cc' failed with exit status 1. I tried to suggestions in the answers to this SO question, but I can't seem to solve it. So I decided to move on again:

How sorting algorithms work
Their sort_unstable algorithm is based on this pattern-defeating quicksort.

Timsort – the fastest sorting algorithm you’ve never heard of
Closely related is pattern defeating quicksort ( https://github.com/orlp/pdqsort ), which adapts quicksort to take advantage of sorted runs. I've adapted a few quicksorts to pdqsort and seen good speedups (as people were often sorting partially sorted data)
Basically: Timsort is to mergesort as pdqsort is to quicksort
- I tried creating a sorting algorithm in C language.

Discussion Thread
I was thinking of optimal C++ over native types. I just spoke up because if your intuition of quicksort is that 50k elements should take 20ms you’re drastically underestimating computer performance. They’re crazy fast and optimized sorting algorithms are downright scary.

Beating Up on Qsort (2019)
Just for fun, I added pdqsort to the benchmark:
https://github.com/orlp/pdqsort
Here are some of the results on an Ivy Bridge hackintosh:
size, qsort, inline, sort, stable_sort, pdqsort, radix7 -
Which sorting algorithm did you implement in your programming language?
sort_unstable is a pattern-defeating quicksort (https://github.com/orlp/pdqsort) added with RFC#1884 (https://github.com/rust-lang/rfcs/pull/1884).
What are some alternatives?
When comparing ZBar and pdqsort you can also consider the following projects:
ZXing - ZXing ("Zebra Crossing") barcode scanning library for Java, Android
fluxsort - A fast branchless stable quicksort / mergesort hybrid that is highly adaptive.
C++ Format - A modern formatting library
American Fuzzy Lop - american fuzzy lop - a security-oriented fuzzer
FastFormat - The fastest, most robust C++ formatting library
quadsort - Quadsort is a branchless stable adaptive mergesort faster than quicksort.
