Commenting Python Code
Programming reflects your way of thinking in order to describe the single steps that you took to solve a problem using a computer. Commenting your code helps explain your thought process, and helps you and others to understand later on the intention of your code. This allows you to more easily find errors, to fix them, to improve the code later on, and to reuse it in other applications as well.
Commenting is important to all kinds of projects, no matter whether they are - small, medium, or rather large. It is an essential part of your workflow, and is seen as good practice for developers. Without comments, things can get confusing, real fast. In this article we will explain the various methods of commenting Python supports, and how it can be used to automatically create documentation for your code using the so-called module-level docstrings.

Alibaba Dragonwell8 : The In-house OpenJDK Implementation At Alibaba
Alibaba requires no introduction. It is one of the popular and largest multinational conglomerate founded by Jack Ma, a business magnate and philanthropist from China. It is also world’s fifth-largest internet company by revenue. It specializes in various sectors such as e-commerce, retail, Internet and technology. Alibaba team has provided significant contribution to open source projects. One such project is OpenJDK. The development team at Alibaba has developed many Java-based applications over the years. They have adopted OpenJDK and created their own JDK named “Alibaba Dragonwell8”. It is the downstream version of OpenJDK and completely open source.
Alibaba Dragonwell is optimized for developing e-commerce, financial, logistics applications which are running on their 100k+ servers. It is certified as compatible with the Java SE standard. It is currently supports Linux/x86_64 platform only. Let us hope they will extend the support to Unix and other platforms soon. In this guide, we will see how to install Alibaba Dragonwell8 in Linux. I have tested this guide on Ubuntu 18.04 LTS server. However, it should work on other Linux distributions as well.
