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.
pdqsort
- Pattern-Defeating Quicksort (Pdqsort)
-
Faster sorting algorithm
I found that this exists: https://github.com/orlp/pdqsort

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.
- Do Low-Level Optimizations Matter?

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).

PEP 744 – JIT Compilation
> It provides a meaningful performance improvement for at least one popular platform (realistically, on the order of 5%).
At first it will not provide a large boost, but it will set the foundations for larger gains in subsequent releases. They link a list of some proposed improvements already underway, with improvement estimates, at https://github.com/python/cpython/issues/115802

Featured Mod of the Month: Phil Ashby
After that, with the basics of software engineering understood, I would move on to a wider use language, with a bigger ecosystem to employ, most likely Python. This would expose me to large system design / distributed systems and architectural challenges...
