• 和 Python 一起来玩 猴子补丁
  • monkey patching

Monkey patching is about replacing attributes of a Python thing with other attributes. Let's use the word "thing" very loosely and have some fun.

(是也乎:

.... unless you really want to. ;-)

讲真, 能作, 和应该作,完全不同, 老老实实平平淡淡干干净净的写代码是最好的了... )

• 通过 Zipkin 在 Python 应用中引入分布式跟踪
  • monitoring, distributed

Distributed tracing is the idea of tracing a network request as it travels through your services, as it would be in a microservices based architecture. The primary reason you may want to do is to troubleshoot or monitor the latency of a request as it travels through the different services.

(是也乎:

主要面向微服务...跨进程/主机/机房... )

• 如何在 Python 中使用 Numpy 描述符统计
  • numpy, statistics

The descriptive statistics we are going to calculate are the central tendency (in this case only the mean), standard deviation, percentiles (25 and 75), min, and max.

• 介绍 Pandas 进行数据分析 - 101
  • pandas

pandas is a software library written for the Python programming language for data manipulation and analysis.

(是也乎:

讲真 Pandas 真的很好用, 前提是数据清洗的要好... )

• Google Cloud 上的 GPU 上跑 Jupyter notebooks
  • docker, jupyter

In a previous post, I listed out the steps to run Jupyter notebooks on GPU instances on GCP Compute Engine. It turns out, there is a much easier and more flexible way. Using Docker containers.

(是也乎:

GUP 在 GCP 中已经成为一个实体对象可以创建了, 然后 CUDA 的协助下, Jupyter 就能跑了... )

• 说,这是什么? TensorFlow
  • TensorFlow

In this article, we will walk through an intermediate-level tutorial on how to train an image caption generator on the Flickr30k data set using an adaptation of Google’s Show and Tell model. We use the TensorFlow framework to construct, train, and test our model because it’s relatively easy to use and has a growing online community.

(是也乎:

其实, 一切都被部署在云端了, 具体怎么来的,谁也不知道, 反正 google 知道, 大家用的越多, 他们就识别的越快...

然后, 再也没有公司能赢的了 google 了.

• Python 中用 感知散列 进行重复图像检测
  • image processing

Jetsetter has hundreds of thousands of high-resolution travel photos, and we’re adding lots more every day. The problem is, these come from a variety of sources and are uploaded in a semi-automated way, so there are often duplicates or almost-identical photos that sneak in. And we don’t want our photo search page filled with dupes.

• 用 Python 管理 corn 任务

  • cron

• Luigi: 一个 ExternalProgramTask 示例 – 将 JSON 转换为 CSV

  • luigi

I’ve been playing around with the Python library Luigi which is used to build pipelines of batch jobs and I struggled to find an example of an ExternalProgramTask so this is my attempt at filling that void.

反正都不一样了... )

• 音频应用程序音频信号处理（Python，NumPy，SciPy，Matplotlib等）
  • Audio

About this course: In this course you will learn about audio signal processing methodologies that are specific for music and of use in real applications. We focus on the spectral processing techniques of relevance for the description and transformation of sounds, developing the basic theoretical and practical knowledge with which to analyze, synthesize, transform and describe audio signals in the context of music applications.
