UPDATE (2018-05-11):

Our team at LodeStream has built a scaffold specifically for Wordpress development. You can check it out today and start play with it. Out of the box, it supports:

• Docker, Docker Compose
• Let’s encrypt HTTPS
• Nginx as a reverse proxy with auto generated config
• Simplified domain configuration
• More information in the repo

Github repo: lodestreams/wordpress-docker-compose

• sudo docker create -v "$PWD":/var/lib/mysql --name dbstore mysql
• sudo docker create -v "$PWD":/var/www/html --name htmlstore php
• sudo docker run --name mysql -e MYSQL_ROOT_PASSWORD=password --volumes-from=dbstore -dp 3306:3306 mysql
• git clone https://github.com/youdarnet/wordpress.git
• sudo docker run -d --name wordpress --link mysql:mysql --volumes-from=htmlstore -p 80:80 youdar/wordpress
• sudo docker run -d --link mysql:mysql -e MYSQL_USERNAME=root --name phpmyadmin -p 3307:80 corbinu/docker-phpmyadmin

Notes:

添加新的 Wordpress 网站：

使用现有的 MySQL 数据库。

• sudo docker create -v "$PWD":/var/www/html --name wordpressNameStore php
• sudo docker run -d --name wordpressName --link mysql:mysql --volumes-from=htmlstore -p 800x:80 youdar/wordpress

其它提示

• Remove dangling volumes: sudo docker volume ls -f dangling=true | awk 'FNR > 1 {print $2}' | xargs sudo docker volume rm

• Run a nginx at current dir: sudo docker run -it --rm -v "$PWD":/usr/share/nginx/html -p 8081:80 nginx

• sudo docker inspect --format="" nginx | json_pp

UPDATE (2016-02-10):

I’ve found there is still a record in ~/Library/Application\ Support/Google/Chrome/Default/Preferences and deleted it, see if it works.

For those of you who suffering from the malicious Chrome plug-in called Webpage screenshot always saying it’s removed automatically…

Try this:

# Fire a commandline up, and go to your Chrome directory
cd ~/Library/Application\ Support/Google/Chrome

# Searching for it
find . -iname 'Webpage Screenshot'

# find out the directory and remove it, in my case:
cd Default/Extensions
rm -rf ckibcdccnfeookdmbahgiakhnjcddpki

If it does the job, then congrats, if not, post your idea below :)

Ideas come to my mind:

• grep -r 'Webpage Screenshot' .
• grep -r 'ckibcdccnfeookdmbahgiakhnjcddpki' .

Express

• Route name couldn’t be /accounts, 404 raised after that.

Node.JS

• Cross require lead target class becomes an empty Object!

  In order to prevent an infinite loop, an unfinished copy of the a.js exports object is returned to the b.js module. b.js then finishes loading, and its exports object is provided to the a.js module. —-https://nodejs.org/api/modules.html

Custom getters

Use custom getters to process the MongoDB retunred data, like an interceptor.

Schema custom getters doesn’t work with lean().

Set up the Schema:

1
2

DBSchema.set('toObject', {getters: true, virtuals: true});
DBSchema.set('toJSON', {getters: true, virtuals: true});

Add custom get function on specified field:

1

DBSchema.path('images').get(function (images) {
  if (images && Array.isArray(images) && images.length > 0) {
    images = images.map(function (image) {
      return getUrl(image);
    });
  }
  return images;
});

Operator delete is unexpectedly slow!

Delete is the only true way to remove object’s properties without any leftovers, but it works ~ 100 times slower, compared to it’s “alternative”, setting object[key] = undefined.

In NodeJS:

require is always “require once”. After you call require the first time, require uses a cache and will always return the same object.

function MyClass () { // constructor function

  this.publicVariable = "bar";  // Public variable 

  this.privilegedMethod = function () {  // Public Method
    alert(privateVariable);

// Instance method will be available to all instance but only load once in memory 
MyClass.prototype.publicMethod = function () {    
  alert(this.publicVariable);
};

// Static variable shared by all instance 
MyClass.staticProperty = "baz";

//...
var myInstance = new MyClass();

搭建一个在国内外都可以访问的 Google Fonts 代理

Google fonts is blocked in China.

– by Google Fonts Unstable in China – Here is How to Fix It

Yah, we all know that. But the general solution for this is awkward to me, Because after I switched the fonts location to http://fonts.useso.com, I can open my blog very quickly inside China, where the useso(360™) located. When I was trying to access it from the outside of China, both Japanese and West American are slow, over 5 seconds to download a 800 Bytes file, That’s unbearable.

Then I tried to use Qiniu as a CDN to cache fonts.googleapi.com, then I realized it’s blocked anyway. Afterwards, I use the CDN to cache fonts.useso.com, still doesn’t work at all, it persist showing me this:

Request tips:

The My Wallet API provides a simple interface Merchants can use interact with their wallet. Blockchain.info will decrypt the wallet on our server manipulate it as necessary and re-save. HTTP GET and POST are supported. However, if a POST request is sent without “Content-Type: application/x-www-form-urlencoded” header, some endpoints may not work correctly.
