Handling real life datasets can be painful when you are used to cleaned and ‘ready-to-use’ datasets that are used in books, tutorials and beginner challenges in Data Science. This tutorial aims to provide some useful tips and codes to get started with the Pandas library and data provided by your company or client.

DeepLearning is a subfield of machine learning that is a set of algorithms and functions inspired by the structure and fucntioning of the brain. TensorFlow is a machine learning framework that Google created and is used to design, build and train deep learning models. This tutorial is an attempt on the MNIST dataset from this Kaggle competition while also explaining the basics of writing TensorFlow code.


这已经是标准的入门嗯哼了, 关键是启动训练集容易建立, 并早已有...

Extending Python has been a core feature of the platform for decades, the Python runtime provides a “C API”, which is a set of headers and core types for writing extensions in C and compiling them into Python modules. But, do you really have to write extensions to Python in C? Why can’t we use something a tad more modern, like Go.


golang 的优良设计之一就是方便的支持 C, 所以, 扩展到 Python 也是相似的工具链


Inspired by several other system builds ($1000, $1700, and forum posts), I decided to have a go and build one. I was a Sr Director of Data Science for a large travel company at the time and was a bit envious of the work being done by the individual scientists. I was also contemplating a change in employment (with some downtime)?—?I wanted to ensure I had access to resources to continue my deep learning leveling-up. Finally, I wanted to make sure I could demonstrate to my kids the Internet’s most important task: distinguishing between “cat” and “not cat”.

For the last ten years, my standard advice to someone looking for a programming language to teach beginners has been start with Python. And now I'm changing that recommendation.


这位老师尝试过 Erlang 作为开蒙的语言? 现在果断推荐上 Javascript...


The other day the idea occurred to me that it would be neat to write a simple Redis-like database server. While I've had plenty of experience with WSGI applications, a database server presented a novel challenge and proved to be a nice practical way of learning how to work with sockets in Python. In this post I'll share what I learned along the way.

Django provides several class based generic views to accomplish common tasks. Simplest among them is TemplateView. TemplateView should be used when you want to present some information in a html page. TemplateView shouldn't be used when your page has forms and does creation or update of objects.
