This year, I experienced a very unpleasant layoff; I was once unable to sleep at night, living in a reversed day-night cycle, constantly wondering if there was something wrong with me. In order to relax, today, a few months later, I arranged for myself to travel alone for more than ten days. One of my target cities is Liupanshui, Guizhou,...

修改Repo地址后Capistrano部署问题

Ruby on Rails Capistrano CI

Feb 28, 2017

We are using Capistrano to deploy our project and recently migrated the project repository from BitBucket to Github. I thought I could just simply change `set :repo_url` in `config/deploy.rb`, but that's not the case.

Jan 10, 2017

By using ActionController::Live, we can achieve real-time Push communication. The official documentation is here http://edgeapi.rubyonrails.org/classes/ActionController/Live.html, but I always feel that this documentation is too abbreviated for learning.

Install Japanese input methed on ubuntu 16.04

在Ubuntu16.04上安装日语输入法

Ubuntu Japanese

Oct 10, 2016

I personally think that it is necessary to install the corresponding input method on PC/Mobile/Mac if you are learning a new foreign language. Usually, our foreign language teachers, in general, will only teach us the language itself, and not too much to teach you how to install input methods.
