Syntactic Sugar
“In computer science, syntactic sugar is syntax within a programming language that is designed to make things easier to read or to express. It makes the language ‘sweeter’ for human use: things can be expressed more clearly, more concisely, or in an alternative style that some may prefer.”

Dependency Injection in Python
“Dependency Injection (DI) is a design pattern that encourages loose coupling, maintainability, and testability within software applications.” Though more often associated with statically typed languages, the pattern can be applied with Python.
PATRICK KALKMAN
依赖注入是一种强大的设计模式，可以促进松耦合、可维护性和可测试性。但是由于Python的动态性，依赖注入用的并不常见

Debugging a Mixed Python and C Language Stack
Debugging is difficult. Debugging across multiple languages is especially challenging, and debugging across devices often requires a team with varying skill. This article describes the process one team uses to debug across a mixed Python/C stack.
ENTSCHEV & ZAITLEN
记录了一次debug的过程，还是很有意思的，最后发现是numba的bug，由于把Python的函数当做回调函数传给了cuda，cuda在回调的时候又拿不到GIL导致的死锁，debug主要用的是gdb，用法学起来肯定不难， 难的是要对Python、Python解释器、Cuda啥的都有了解才能debug。Python和C混合编程确实要注意很多，debug也要更加注意

The Many Problems With Celery
“Celery is the de facto solution for background workers and cron jobs in the Python ecosystem, but it’s full of footguns.” This article describes the problems and offers some solutions.
STEVE DIGNAM
很好的一篇文章，主要介绍了Celery的一些问题，同时还贴心的给出了怎么解决（虽然大部分都解决不了，只能忍受或者自己搞）,正好最近打算用Celery做个算法任务调度的系统。 确实文章中说的一些问题是存在的，而且有的比较坑，但是确实Celery现在是Python领域的消息队列事实标准，没有更好的选择了，像其他的消息队列框架功能又 太少，完全是玩具状态没法用。所以当前这个时间节点来看，也只能凑合用Celery，遇到具体的问题再去想办法解决吧。强烈建议写代码之前先看一遍Celery的配置文档， 多多少少能提前看到一些坑。
