I need to store lots of data and with each entry there is a Facebook user id to whom data belongs to. What is the best way to store this in #mongodb?

Is one collection with entries like this will be fine?

{
  "stuff": { ... },
  "id": "<facebook-user-id>"
}

Later I will need this do display his own stuff to the logged in user.

Here is the task.

I've got two directories: A and B (two versions of a same library).

I need to list all the files in A where git diff between file from A and from B is longer than 2 lines.

What is the cleanest way of doing this in #bash?

Yet another javascript quiz task. Do not hurt your brain too much :-) More under the cut

#Clojure is awesome. This is my first lispy language and I really got a "wow" moment. When writing in Clojure after Ruby of Javascript you need to completly change the way you think about programs. Remember 'everything is an object'? Now everything is a function! More under the cut

So we have a linked list and we would like to reverse-print it's values.

var someList = {
       value: 1,
       next: {
                value: 2,
                next: {
                          value: 3,
                          next: {
                                   value: 4,
                                   next: null
                          }
                }
       }
};

Ok, #ruby guys, it is time to show your real power. Here is the task. Write a program, which outputs numbers from 0 to 1000 without: More under the cut

Use jshint. It is available for all platforms (Textmate, Sublime, etc.). Real-time error highlighting will save you a lot of time.

debugger; statement. Insert it in suspicious places, same as breakpoint, but is not affected by code changes. The killer feature is scope access: use console to output 'this', which will be bound to the scope you're in. More under the cut

alias l='ls -trlah'

more productive ls:

• -tr to sort modified asc, last modified will be in the end of output
• -l for permissions
• -a for hidden 'dot' files
• -h for human readable size

#unix #bash

Simple example for the mongoose 'populate' feature: referencing objects from each other. More under the cut
