Interpreted language will never match the performance of compiled languages . Ever since I moved on to python from C/C++ , I always wanted to combine best of both worlds by extending python in C .

(是也乎:

这事儿地球人都知道, M$ 还嫌 C 性能差在 C++ 代码中嵌汇编呢...

问题是, 首先功能稳定后, 还得找到性能瓶颈再针对性替代, 光这个工程就不简单了...

I’ve been using Excel for data cleaning until I discovered how powerful pandas are for data analysis and data cleaning. In this article I want to go over basics of how to use pandas for cleaning data in excel files.

(是也乎: 数据源是 excel 文件...细思恐极了..

Fisher’s Linear Discriminant Analysis (LDA) is a dimension reduction technique that can be used for classification as well. In this blog post, we will learn more about Fisher’s LDA and implement it from scratch in Python.

This post is a deep-dive into programmatically trading on the Ethereum / Bancor exchange and exploiting a game-theoretic security flaw in Bancor, a high-profile smart contract on the Ethereum blockchain.

In Python, a class can inherit features and attributes from multiple classes and thus, implements multiple inheritance. MRO or Method Resolution Order is the hierarchy in which base classes are searched when looking for a method in the parent class.

The simplest way to serve HTTP/2 is to use the Quart framework, furthermore Quart is the only Python framework to support server-push.

Imagine that you are developing a machine learning model to classify articles. You have managed to get an unreasonably large text file which contains millions of identifiers of similar articles that belong to the same class. You are unsure whether identifiers that are close to each other are independent.

Medium has a large amount of content, a large number of users, and an almost overwhelming number of posts. When you try to find interesting users to interact with, you’re flooded with visual noise. I define an interesting user as someone who is from your network, who is active, and who writes responses that are generally appreciated by the Medium community.

可惜, Medium 第一时间和谐掉了...

Clustering is a type of Unsupervised learning. This is very often used when you don’t have labeled data. K-Means Clustering is one of the popular clustering algorithm. The goal of this algorithm is to find groups(clusters) in the given data. In this post we will implement K-Means algorithm using Python from scratch.

mailproxy is a simple SMTP proxy. It receives emails through an unencrypted, unauthenticated SMTP interface and retransmits them through a remote SMTP server that requires modern features such as encryption and/or authentication. mailproxy is primarily useful for enabling email functionality in legacy software that only supports plain SMTP.

(是也乎:

简单的说, 就是个简单的可内置的 SMTP 服务器?

基本上就是将 python 的默认交互提升到了普通的 shell 水平.. 只是, 有了 ipynb 为毛要用普通的 REPL ?

中国的PyCon大会已经组织了6年,在第7年PyCon大会之际,Python3已经成熟,比如Instagram迁移到了Python3。而人工智能方兴未艾,区块链、物联网、AR、VR、机器人等领域创新不断涌现。

本大会以“大数据和人工智能技术的创新应用”为主题,将由丰富的内容和议题组成,着重探讨如何使用Python技术进行大数据和人工智能的技术开发和最佳实践,并结合具体的产品和行业发展趋势,分享不同类型的应用、场景下的开发和运营经验。
