• 用 nvc++ 和 Cython 在 GPU 上加速 Python
  • ASHWIN SRINATH

Python on GPUs has become a big topic for processing big data and scientific computing. In this article from the NVIDIA Developer Blog, you’ll learn how to leverage C++ in Python using Cython and the nvc++ library. There’s even a real-world example that illustrates the Jacobi method to solve a heat equation.

• 从 Github 下载了 10,000,000 Jupyter 笔记本: 学到的东西
  • ALENA GUZHARINA

The JetBrains Datalore team downloaded ten million Jupyter Notebooks and analyzed them to determine things like which languages were the most popular, what kinds of content are in notebook cells, and how consistently notebooks can be reproduced. It’s a fascinating look into trends in data science technology!

Learn how to customize Django’s admin with Python. You’ll use AdminModel objects to add display columns, calculate values, link to referring objects, and search and filter results. You’ll also use template overriding to gain full control over the admin’s HTML.

• 解答布尔运算
  • BRETT CANNON

In the latest entry to his series on syntactic sugar, Brett Cannon explores boolean expressions. You’ll learn how boolean expressions “short circuit” and, as an unexpected bonus, a peek into how CPython “cheats” at variables.

当年大家联合翻译过很多版本, 俺的

美丽好过丑陋,
浅显好过隐晦,
简单好过复合,
复合好过复杂,
扁平好过嵌套,
稀疏好过密集,
可读性最重要,
即使祭出实用性为理由,
    特例也不可违背这些规则.

不应默认包容所有错误,
    得由人明确的让它闭嘴;

面对太多的可能,不要尝试猜测;
应该有一个(且唯一)直白的解决方法;
当然,找到这个方法不是件容易的事
    ~谁叫你不是荷兰人呢?
但是: 现在就做比永远不做要好;

若实现方案很难解释,
那么它就不是一个好方案;
反之也成立;-)

名称空间是个绝妙想法.

--现在就来共同体验和增进这些吧!
