六盘水半程马拉松，以及读《当我谈跑步时我谈些什么》

Run Book Review Excerpt

Jul 23, 2017

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,...

How to Deploy with Capistrano after Repo URL changed?

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. When I executed the deployment with Cap, I saw that the code in the log was still taken from the BitBucket repo, and all the changes...

Implement HTTP Long Polling in Rails with Action Controller Live

在Rails中实现HTTP Long Polling

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. The main techniques used here are these: When the HTTP/1.1 Header is specified as Transfer-Encoding: chunked, the data will be chunked and returned continuously

How to undo a git reset hard and branch delete

Git 找回reset --hard的代码及删除的分支

Dec 26, 2016

People make mistakes all the time. I remember the first time I used `git reset --hard` + `git push -f` was in early 2013. I thought it was just a small commit, but I ended up pushing a bunch of useless code to github. What should I do? At this time, some seniors came out and told me that even...

人生第一个全程马拉松

Dec 13, 2016

A full marathon, 42.195km, is a distance I never dared to imagine I could complete two years ago. However, just last weekend, December 11, 2016, I completed the first full marathon of my life in Guangzhou. Net time of 5 hours and 12 minutes, not a very good time (mainly due to lack of training for long distances and having...

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. As for the installation of Japanese input methods, we realized that...

## New Features of Object ## Shorthand syntax ES2015 has such a syntactic sugar that when a new Object is generated, it can have a shorthand when the key name is the same as the variable name. See the following example for exactly how to write it. In the past, we needed to write it like this: ```js function buildUser(first,...

## New Features of Array ## Array Destructing It feels like a way to learn from Ruby or similar languages. In ES5, we didn't have a way to directly assign individual values of an array to multiple variables at once, but now we can, assuming we have such an array: ```js let users = [ 'Hegwin', 'Jason', 'Ken' ]; ```...
