DRF 中有个著名的 "N+1选择问题", 这儿进行了深入的讨论, 但是,并没有什么好的的解决方案..

The Django REST Framework (DRF for short) allows Django developers to build simple yet robust standards-based REST API for their applications. Even seemingly simple, straightforward usage of the Django REST Framework and its nested serializers can kill performance of your API endpoints. At it’s root, the problem is called the “N+1 selects problem”; the database is queried once for data in a table (say, Customers), and then, one or more times per customer inside a loop to get, say, customer.country.Name. Using the Django ORM, this mistake is easy to make. Using DRF, it is hard not to make.

模块选择特定平台 I/O 监察功能. 相当于 POSIX 中的 select() , 适用于 Windows 和 UNIX 平台. 也提供了 poll() , 仅 UNIX 可用.

作为 Python 程序猿,每天都在使用 pip 进行各种模块的管理. 但是从来没有详细探寻过为什么/怎么来的?! 这次请到了作者来聊聊,当初的设想…

As Python developers we have all used pip to install the different libraries and projects that we need for our work, but have you ever wondered about who works on pip and how the package archive we all know and love is maintained? In this episode we interviewed Donald Stufft who is the primary maintainer of pip and the Python Package Index about how he got involved with the projects, what kind of work is involved, and what is on the roadmap. Give it a listen and then give him a big thank you for all of his hard work!

Main goal of developing this framework is to be able to edit any workflow item on the fly. This means, all elements in workflow like states, transitions, user authorizations(permission), group authorization are editable. To do this, all data about the workflow item is persisted into DB. Hence, they can be changed without touching the code and re-deploying your application.

When people think computational geometry, in my experience, they typically think one of two things: Wow, that sounds complicated. Oh yeah, convex hull. In this post, I’d like to shed some light on computational geometry, starting with a brief overview of the subject before moving into some practical advice based on my own experiences

Hey guys, Recently, I informed my manager that I was willing to go above-and-beyond and help improve some of our team operations by writing a handful of Python scripts. He is a stickler for following the rules, so he ordered me to ask permission to install Python on my development machine (I wasn’t intending on asking permission). My request has been refused. Despite providing evidence from the Python Foundation on their open licensing (especially for my purposes, which is just local machine — not production), they are still refusing on account that Python is type of GPL and it is interpretative. Have you guys run into something like this before? It seems ridiculous to me.

( 是也乎:

嗯哼, 可怜的 GPL. )

If the title doesn’t make any sense, then there’s no hope that the description will be any better. This talk will be a strange dive into interpreter hacks, the pointlessness of the Python 2 vs 3 debate, and the twisted artistic drive that pushes the speaker to come up with these perversions of the Python language. Prepared to be simultaneously repulsed, intrigued, and completely bored.
