- Pycon 2017 议题选择
- pycon
The acceptance and rejection letters for pycon arrived this week and so did the final list of selected talks for Pycon US 2017.
(是也乎:
相对国外的 PyCon 都是年头儿对上年回顾,中国的总是挤在年尾回顾当年... 因为春节哈... )
- Python 异步 I/O 嗯哼
- video, asyncio
In this 90-minute video series, I walk through a book chapter about asynchronous I/O in Python called A Web Crawler With asyncio Coroutines, which was co-authored by the creator of Python.

- Instagram 关闭了 Python 的 GC
- memory management, garbage collection
By dismissing the Python garbage collection (GC) mechanism, which reclaims memory by collecting and freeing unused data, Instagram can run 10% more efficiently. Yes, you heard it right! By disabling GC, we can reduce the memory footprint and improve the CPU LLC cache hit ratio. If you’re interested in knowing why, buckle up!
(是也乎:
随着 Py 在生产线上越来越嗯哼, 对 GC 的怨念总是在积累,终于,这一天来了... )
I want to focus exclusively on the process of reshaping data, i.e. converting or transforming data from one format to another. data manipulation
(是也乎:
不仅仅是格式转换, 更要有垃圾清理... )
Complexity science is one of my favourite topics, ever. Studying complexity is how I ended up in the computer science bandwagon in the first place, and I constantly find myself thinking about how individual agents’ decisions affect the overall state of systems. Self-organization and emergence are fundamental aspects of how the pieces of the complexity puzzle fit together, and Wolfram’s elementary cellular automata are a great way to understand them.

Wolfram 安身立命的核心技术, 成熟运行20多年, 哪儿这么简单的可以嗯哼出来哪... )
- 加速 Python
- performance, benchmarking
This blog post gives an introduction to some techniques for benchmarking, profiling and optimising Python code.
(是也乎:
又一个收集各种技巧的 blog ,不过, Python 的本意就不是为了运行时速度哪, 而是开发时效率... 所以... )
Writing consistent, well-formed code is important. Of course the functionality of the code is paramount, yet in addition the styling and structure should follow a commonly accepted standards. Not only will it make the code more approachable to others, but also to yourself, when you return to an old piece of software, which you have not looked at for months or even years. You might even squash some bugs early on, by writing code in consistent manner. The process of styling and checking of these code qualities, is often referred as linting.

- 黑客统计
- Jupyter notebook
I've chosen to start with Harvard's Data Science course. I'm currently on week 3 and one of the suggested readings for this week is Jake VanderPlas' talk from PyCon 2016 titled "Statistics for Hackers". As I was watching the video and following along with the slides, I wanted to try out some of the examples and create a set of notes that I could refer to later, so I figured why not create a Jupyter notebook.
(是也乎:
一份课堂作业,总是可以嗯哼到 ipynb 中来... )
- 用 Python 来开始 Spark Streaming + Kafka
- kafka, spark
In this article I am going to look at Spark Streaming. This is one of several libraries that the Spark platform provides (others include Spark SQL, Spark MLlib, and Spark GraphX). Spark Streaming provides a way of processing "unbounded" data - commonly referred to as "streaming" data. It does this by breaking it up into microbatches, and supporting windowing capabilities for processing across multiple batches. You can read more in the excellent Streaming Programming Guide.
