Multiple SSH Keys settings for different github account

create different public key

$ ssh-keygen -t rsa -C "[email protected]"

Pub/sub with MongoDB and Node.js

Setup:

$ mongo

> db.createCollection('messages', { capped: true, size: 100000 })
> db.messages.insert({})

Sort object properties by value (values are text)

I have following object:

var cities={10:'Tashkent', 14:'Karakalpakiya', 16:'Andijan'};

I want sort it by city names, so after sort it should be:

var cities={16:'Andijan', 14:'Karakalpakiya', 10:'Tashkent'};

But I can't sort object properties, instead can convert object into array, then sort items.

Commit, clone a container

To 'clone' a container, you'll have to make an image of that container first, you can do so by "committing" the container. Docker will (by default) pause all processes running in the container during commit to preserve data-consistency.

For example;

docker commit --message="Snapshot of my container" my_container my_container_snapshot:yymmdd
