  • Arduino 微控制嘼 + Python: 入门
    • REAL PYTHON Discover how to use Arduino microcontrollers with Python to develop your own electronic projects. You’ll learn how to set up circuits and write applications with the Firmata protocol. You’ll control Arduino inputs and outputs and integrate the board with higher-level apps. (是也乎: Arduino 比 树莓派 其实不差… Arduino 只是, 上手嵌入系统, 电工一系列工具就得先准备并熟练了.. )
  • 为 Python 编写个 LLVM 专业工具
    • STEPHEN DIEHL “We’re going to build a single module Numba-like compiler for Python. It won’t be nearly as featureful or complete, but should demonstrate how you can go about building your own little LLVM specializer for a subset of Python or your own custom DSL expression compiler; and integrating it with the standard NumPy/SciPy stack for whatever scientific computing domain you work.”
  • Python 2.7.17 发布
    • PYTHON.ORG Python 2.7.17 is a bug fix release in the Python 2.7.x series. It is expected to be the penultimate release for Python 2.7. 详细变更说明….
  • Python 代码复杂性瀑布
    • NIKITA SOBOLEV What can be done to prevent your Python code from getting too complex? A good linter setup does much more than finding missing commas and bad quotes. A good linter allows you to rely on it with architecture decisions and help you with the refactoring process. (是也乎: 还是得靠 linter 工具, 因为工程师总是不自主的在工程中将代码越写越复杂… )
  • 在 Python 中重新实现 Solaris 命令使 C 语言的性能提高了17倍
    • DARREN MOFFAT “As a result of fixing a memory allocation issue in the /usr/bin/listusers command, that had caused issues when it was converted to 64 bit, I decided to investigate if this ancient C code could be improved by conversion to Python.” (是也乎: 涉及性能, 古老的锅/坑总是 C 挖的… 现在, Python 也有机会来填/挖了… )
  • Y组合器的简单本质(用Python解释)
    • LIONEL PARREAUX “The Y combinator is a central concept in lambda calculus, which is the formal foundation of functional languages. Y allows one to define recursive functions without using self-referential definitions.” (是也乎: 经典思想总是值得反复嗯哼的… 反正无论怎么推导,虽然总是能成功, 但是, 就是无法相信自己的眼睛… 直觉上中间一定有谁偷走了什么… )
  • 大规模 Python: 严格的模块
    • CARL MEYER The Instagram engineering team is experimenting with a technique for writing Python modules that are side-effect-free on import to reduce server startup time and unexpected global state changes. (是也乎: 好吧, 什么事儿数量一多都不容易…. )
  • Python 属性访问和描述符协议
    • AMIR RACHUM A deep dive into Python attribute access and the descriptor protocol. What exactly happens when we say foo.bar?

  • time.sleep() : 如何在代码中添加时间延迟
    • REAL PYTHON Learn how to add time delays to your Python programs. You’ll use decorators and the built-in time module to add Python sleep() calls to your code. Then, you’ll discover how time delays work with threads, asynchronous functions, and graphical user interfaces. (是也乎: Delays 延迟制造… )
  • Django 开发常犯的 7个错误
    • TOMASZ BĄK
    • • Shared by Tomasz Bąk “Django is powerful web framework, but with power comes responsibility. In this article, we will cover common mistakes that are even seasoned Django developers make, yet most successful Django projects need to deal with these sooner or later.” (是也乎: 一切常见错误, 都是对 Django 设计思想误解造成的…

… with power comes responsibility

能力带来责任 )
