This is a proof-of-concept implementation of CPython that supports multithreading without the global interpreter lock (GIL), from Facebook research. An overview of the design is described in the Python Multithreading without the GIL Google doc. Also see the related discussions on LWN and Hacker News.

• 为毛不应该直接调用 setup.py ?
  • PAUL GANSSLE

“The setuptools team no longer wants to be in the business of providing a command line interface and is actively working to become just a library for building packages. What you should do instead depends on your use case, but if you want some basic rules of thumb, there is a table in the summary section.”

• 在哪儿观察努力? 查阅 Python 核心开发人员活动
  • ŁUKASZ LANGA

“One of the tasks given me by the Python Software Foundation as part of the Developer in Residence job was to look at the state of CPython as an active software development project. What are people working on? Which standard libraries require most work? Who are the active experts behind which libraries?”

• 测试是不够的: 向 urllib3 添加类型提示后/案例研究
  • SETH MICHAEL LARSON

“Since Python 3.5 was released in 2015 including PEP 484 and the typing module type hints have grown from a nice-to-have to an expectation for popular packages. To fulfill this expectation our team has committed to shipping type hints for the v2.0 milestone. What we didn’t realize is the amount of value we’d derive from this project in terms of code correctness.”

不觉中蟒周刊快译已经到了第9个年头

去年开始有小伙伴加入承担 pythonisa 周刊的翻译, 从来没提醒过, 可就这么默默坚持下来了...

问为什么:

[皱眉]每周新闻资讯 怎么能错过 
看看有什么新东西 
当有新的发现时：
    what f**k 还能这样玩？ 还有这东西？
    每周开彩蛋[吃瓜]

无法同意更多... 很多社区贡献看起来辛苦, 其实受益最多的, 就是主动承担者也.
