    and result is 874. but result isn't listed into answers and can you tell me question more clearly?
    Homework 2.1, is the mini-backup method b = db.products_bak some kind of convention?
    so i can backup any collection by simply adding “_bak” on any collection name? such as db.users_bak?

    Hi, I'm trying to install mongo-edu from https://github.com/przemyslawpluta/mongo-edu/wiki/Installation
    I've flowed the steps in the install guide but I'm getting an error,
    no such file or directory 'usr/lib/node_modules/mongo-edu/node_modules/youtube-dl/bin/youtube-dl'

    do I need to clone the repo first and run the command from within the folder?

    when I ran npm install mongo-edu -g it failed with permission denied and suggested i run with admin or root privileges so i did that as sudo and got the above error no such directory etc

    Hey all, looking for help with the mongo for developers using Pymongo (week 2, hw2.2) if there's anyone around

    hi i can you make a small readme stating the changes need to be made to download mongo-edu
    Hi all, any chance I could get some help with using the mongo nodejs driver?
    I have a question regarding the use of $push in $group aggregation. Is there a way to push data without creating a new array? E.g. round_funding: { $push: "$funding_rounds.raised_amount”} creates an array in an array, like so - round_funding: [ [1,2,3,4,5,6 ] ]. Whereas I would like to see round_funding: [ 1,2,3,4,5,6 ].

    Hi All,
    I saw this forum when I search for MongoDB in gitter.

    I am new here and is this a forum for Mongo DB newbies? Who are mentor(s) here?
