• 最关键的 Python 代码指标
  • STEVE DOWER

“Code metrics are a popular way to analyse the complexity of our software. For some reason, we are attracted to single-figure summaries of quality, whether it’s lines of code, cyclomatic complexity, or the Pylint score. Personally, I think using these are about as valuable as judging another person based on one of their visible or measurable characteristics.”

(是也乎:

对 圈复杂度 们的叕一次私人反击, 但是, 资本将重构一切.

一直低调赚钱的 ACTIVESTATE , 发布的 Python 发行版本可以说是最稳定的一支; 他们心目中的 ML 模块是:

#10 Matplotlib
#9 Natural Language Toolkit (NLTK)
#8 Pandas
#7 Scikit-learn
#6 Seaborn
#5 NumPy
#4 Keras
#3 SciPy
#2 Pytorch
#1 TensorFlow

嗯哼, 有两个纯粹可视化模块...

以及, TF 完胜 PyTorch ...

What makes a good log? When should you log something, and when is logging overkill? In this opinion piece, Nikita Sobolev argues that logging isn’t always best-practice in an application and discuss some alternatives that might make better sense from a business perspective.

• 针对 Django 服务层
  • JAMES BENNETT

“[On the] recommendation to add a ‘service layer’ to Django applications. The short version of my opinion on this is: it’s probably not what you want in Django apps.”

• 文档即是建立社区的一种方式
  • MELISSA MENDONÇA

Why is it so difficult to write good documentation? Why are documentation authors for projects often invisible? In this article, Melissa Mendonça investigates the answers to these questions and describes a new NumPy Enhancement Proposal that aims to restructure the NumPy documentation, build a documentation team, and diversify the contributor base.

• 研究人口动态的框架
  • DUSTIN MCINTOSH

“World Wandering Dudes is a simulation framework in which you initiate a ‘world’ which consists of a ‘field’ and a set of ‘creatures’ (dudes). The field has food on it. Each day, the creatures run around gathering the food which they need to survive and reproduce.”

• 如何在 Python 中进行二分法搜索
  • REAL PYTHON

Binary search is a classic algorithm in computer science. In this step-by-step tutorial, you’ll learn how to implement this algorithm in Python. You’ll learn how to leverage existing libraries as well as craft your own binary search Python implementation.

• 为毛 Iterable 为空时 all() 返回 True?
  • CARL JOHNSONS

Does it make sense for all() to return True for an empty list? Is “all unicorns are blue” a true statement? Does shaving your dog contradict the statement “all mammals have fur?” You’ll have to read to find out!

文科生的战斗, 虽然没办法象 wuhan2020 们那样快速组织工程师, 先于国家完成各种实用系统;

但是, 文科生通过大量海外报道的浏览/对比/翻译/报道/...

可以帮助人们通过真实世界的反应, 来更好的理解当前状态.

而且, 一个完全没有技术基础的文科团队, 自然通过 github 完成所有协同, 实在..感动 -> github 太好用了.
