• 与 Python 中长时间运行的子进程交互
  • debugging

The Python subprocess module is a powerful swiss-army knife for launching and interacting with child processes. It comes with several high-level APIs like call, check_output and (starting with Python 3.5) run that are focused at child processes our program runs and waits to complete. In this post I want to discuss a variation of this task that is less directly addressed - long-running child processes.

作者脑补出了几种方案, 但是,都不嗯哼... 其实吧长时间运行, 要不服务化, 要不事务化, 就别想着中间还能嗯哼什么, 毕竟这是冯机体系不是代码和运行时一致的 LISP 世界. )

• 探索并清洗科学家联盟的卫星数据库
  • data science

The Union of Concerned Scientists maintains a database of ~1000 Earth satellites. For the majority of satellites, it includes kinematic, material, electrical, political, functional, and economic characteristics, such as dry mass, launch date, orbit type, country of operator, and purpose. The data appears to have been mirrored on other satellite search websites, e.g. http://satellites.findthedata.com/ . This iPython notebook describes a sequence of interactions with a snapshot of this database using the bayeslite implementation of BayesDB, using the Python bayeslite client library. The snapshot includes a population of satellites defined using the UCS data as well as a constellation of generative probabilistic models for this population.

  • machine learning, scikit-learn

Today, let’s learn how to build a simple linear regression model using Python’s Pandas and Scikit-learn libraries. Our goal is to build a model that analyses customer data and solves a problem for a (simulated) e-commerce business.

• FAT Python : Python优化的下一章

  • optimization

The FAT Python project was started by Victor Stinner in October 2015 to try to solve issues of previous attempts of “static optimizers” for Python. Victor has created a set of changes to CPython (Python Enhancement Proposals or “PEPs”), some example optimizations and benchmarks. We’ll explore those 3 levels in this article.

  • f-strings

It has been a long time coming, but I am now actively migrating existing projects to Python 3. Python 3.6 specifically, because when I am done I will be able to take advantage of my new favourite feature everywhere! That feature is f-strings.

• Seashells

  • project

Seashells lets you pipe output from command-line programs to the web in real-time, even without installing any new software on your machine. You can use it to monitor long-running processes like experiments that print progress to the console. You can also use Seashells to share output with friends!
