Before we can sign up for a certificate we have to generate a RSA private key
|
1 |
openssl genrsa -des3 -out example.com_secure.key 2048 |
You will be prompted to provide a passphrase(required). The key file is secured with this passphrase but we will eventually remove this protection.
Then, we will use this private key to generate a certificate signing request which is then submitted to the CA.
|
1 |
openssl req -new -key example.com_secure.key -out example.com.csr |
Before we start configuring HTTPS Server we have to make sure to remove the passphrase from our RSA key. Otherwise you have to provide the password every time server started.
|
1 |
openssl rsa -in example.com_secure.key -out example.com_secure.key |
The unencrypted private key should only be readable by the owner of the Nginx or Apache master process. Most of the time this is the root user:
|
1 2 |
chmod 400 example.com_secure.key sudo chown root:root example.com_secure.key |
|
1 |
openssl x509 -req -days 365 -in example.com_secure.csr -signkey example.com_secure.key -out example.com_secure.crt |

“Ask yourself what you want for yourself and your life in the next year. What is it that you want to offer the world? Who do you want to be, what do you want more of in your life? And then ask: How might I get there?”
Psychologist Kelly McGonigal explains how to make resolutions that lead to real change:
node and npmInstall jsbin
npm install jsbin or npm install -g jsbin
if have node not found problem, link it to `/usr/bin
ln -s /usr/local/bin/node /usr/bin/node
Clone jsbin project form github
git clone [email protected]:remy/jsbin.git
Jsbin configuration settings
Go to jsbin project folder
cp config.default.json config.local.json and modify it.
mkdir tmp; mkdir tmp/pids and chmod 777 tmp/pids
Install init.d script
vim /etc/init.d/jsbin and chmod +x /etc/init.d/jsbin
Change {userid} to your user id.

var evtObj = {} _.extend( evtObj, Backbone.Events ); |
| Method | Note |
|---|---|
| object.on(event, callback, [context]) | 註冊監聽一個事件, 並指定觸發 callback, 如果需要在 callback function 中改變 this 的對象, 將對象傳入 context |
| object.off([event], [callback], [context]) | 取消監聽事件, 不指定事件將取消所有的事件 |

var Model = Backbone.Model.extend({ }); var ChildModel = Model.extend({ }); |
| Properties / Method | Note |
|---|---|
| constructor() | You can use Backbone.Model.apply(this, arguments) to invoke constructor function of parent class |
| initialize() | If you definean initialize function, it’ll be invoked when the model is created. |
| defaults | Remember that in JavaScript, objects are passed by reference, so if you include an object as a default value, it will be shared among all instances. Instead, define defaults as a function. |
| attributes | If you’d like to retrieve and munge a copy of the model’s attributes, use _.clone(model.attributes) instead. |
| validate(attrs, options) | By default validate is called before save, but can also be called before set if {validate:true} is passed. Return your custom error message, and it will be stored to validateError |
| isValid() | Run validate() to check the model state. |
| validationError | The value returned by validate during the last failed validation. |
set() get() |
set(‘attr’, ‘value’) or set({ attr: value}) |
| destroy() | You can use _.invoke() to call destroy function for a batch of models. ex: _.invoke(modelsArray, 'destroy') |
|

var Collection = Backbone.Collection.extend({ }) |
| Properties / Method | Note |

| Properties / Method | Note |
|---|---|
| tagName | |
| id | |
| className | |
| attributes | |
| el and $el | |
| events | |
| render() | A good convention is to return this at the end of render to enable chained calls. |
