I developed a Wechat Mini Program but was unable to relase it. The Problem Can I write a software to automate this? This way people don’t have to fumble through all groups they are in and match based on their luck. There are two parties, the one that offers rides, the other looks for a ride. I can create a marcket place for users to publish, subscribe to and arrange the trip.

Can the Same Process Serve Both WebSocket + Http Rquest? (why is this an important question to ask) When building the chat app, we want to serve socket traffic to tell when a user is online and have the message be send as socket data package. The application also have some other functionality such as login/logout. Those are typically served by http protocols. This is because the server has no need to push to client for these features.

I am working on the MIT Distributed System class Spring 2020 6.824.

Challenge I was doing a little refactor for a codebase I worked in. The idea is to collect all free form environment variables into one class to have a centralized place to manage them all to simplify maintanence work. It was a simple task on the surface, but I ran into problems when structuring my unittest. The challange was realted to how Python handles class static variables. Python Class executes once when it is first loaded and then cached.

I run into some challenges setting up the APISIX test. Documenting it here for my furture self. The overall step looks like this, # get source $ git clone git@github.com:apache/incubator-apisix.git $ cd incubator-apisix # prepare runtime and start apisix process $ etcd --enable-v2=true & $ make init # create config files $ make deps $ make run # install required test-nginx repo to sibling file path $ git clone https://github.com/openresty/test-nginx.git .
