上次的问卷结果出来了... )

• 俺们如何部署 Python 代码 ? - Nylas
  • deployment

Building, packaging, and deploying Python using versioned artifacts in Debian packages. At Nylas, we’ve developed a better way to deploy Python code along with its dependencies, resulting in lightweight packages that can be easily installed, upgraded, or removed. And we’ve done it without transitioning our entire stack to a system like Docker, CoreOS, or fully-baked AMIs.

(是也乎:

老梗了,两年前就推荐过,这团队折腾到最后使用了 Debian 专用的 dh-virtualenv 工具, 对于多数团队而言,嗯哼的... )

• 如何进行代码格式化令你的 Python 出色?
  • code-quality

In Python code reviews I’ve seen over and over that it can be tough for developers to format their Python code in a consistent way: extra whitespace, irregular indentation, and other “sloppiness” then often leads to actual bugs in the program. Luckily automated tools can help with this common problem. Code linters make sure your Python code is always formatted consistently – and their benefits go way beyond that.

• 如何成为对冲基金的 Python 程序猿, by the CTO of AHL
  • interview

We asked Collier what it takes to code in Python for a major quant fund. – And whether learning how to code as a second career after trading is actually viable. This is what he said.

AHL?! 折腾宇宙奥密的 CTO 也转行基金了!? 突然理解了 洪教授... )

• 计算科学和工程的 Python 3
  • book

It's a free book available for download. This text summarises a number of core ideas relevant to Computational Engineering and Scientific Computing using Python. The emphasis is on introducing some basic Python (programming) concepts that are relevant for numerical algorithms. The later chapters touch upon numerical libraries such as numpy and scipy each of which deserves much more space than provided here. We aim to enable the reader to learn independently how to use other functionality of these libraries using the available documentation (online and through the packages itself).

• Django, fast: part 2
  • django

In this second follow-up post Patryk Zawadzki makes use of wrk benchmarking tool and shows us the performance of gunicorn, uwsgi, PyPy. Besides benchmarking there is good insights into do's and don't of each deployment option.

• Python 内存管理
  • memory management

One of the things you should know, or at least get a good feel about, is the sizes of basic Python objects. Another thing is how Python manages its memory internally.

  • performance

• 用 HTRC 特性提取器在 Python 中折腾文本挖掘

  • data mining

We introduce a toolkit for working with the 13.6 million volume Extracted Features Dataset from the HathiTrust Research Center. You will learn how to peer at the words and trends of any book in the collection, while developing broadly useful Python data analysis skills.

细思恐极哪, Awesome 系列是 github 中实事上的好物集锦前缀, 但是, Django Admin 只是一个框架中的一个功能,竟然也能攒出一个 Awesome 来... 这得复杂到什么地步哪... )

• violentshell/rollmac
  • 89 Stars, 13 Fork

Free networks often impose either a time or data restriction and this can be used quickly. When this happens you can change your mac address and reconnect, but this is annoying, and it takes time. In addition, most networks will ask you to re-accept the terms and conditions of the network in order to continue. Rollmac is designed to automate this process by using the WPAD protocol to discover the login page and automatically re-accept the terms and conditions.
