How do you sort the below object based on the value in Javascript?

{
     "en": "English (English)",
     "fa": "French",
     "ar": "العربیه",
     "zh": "中文 (Chinese)"
 }

Well first you need to make an array of arrays:

var sortable_langs = [];
 $.each(languages, function(index, language) {
     sortable_langs.push([index, language]);
 });

 sortable_langs.sort(function(a, b) {
     if(a[1] < b[1]) { return -1; }
     if(a[1] > b[1]) { return 1; }
     return 0;
 });

NOTE: a[1] and b[1] refers to the language value like: English (English). They are compared with each other. If a[1] is bigger than b[1] then it will be moved to the first to the top.

In-place value swapping

# Let's say we want to swap
# the values of a and b...
a = 23
b = 42

# The "classic" way to do it
# with a temporary variable:
tmp = a
a = b
b = tmp

# Python also lets us
# use this short-hand:
a, b = b, a

How to get only numbers in textbox using jQuery?

// Restricts input for each element in the set of matched elements to the given inputFilter.
 (function($) {
     $.fn.inputFilter = function(inputFilter) {
     return this.on("input keydown keyup mousedown mouseup select contextmenu drop", function() {
         if (inputFilter(this.value)) {
         this.oldValue = this.value;
         this.oldSelectionStart = this.selectionStart;
         this.oldSelectionEnd = this.selectionEnd;
         } else if (this.hasOwnProperty("oldValue")) {
         this.value = this.oldValue;
         this.setSelectionRange(this.oldSelectionStart, this.oldSelectionEnd);
         }
     });
     };
 }(jQuery));

 // restrict input to receive just numbers
 $("#my_input_num").inputFilter(function(value) {
     return /^\d*$/.test(value);
 });

In Google OAUTH 2.0 in case you get a token from Google Login you can get user's information for that token by sending a simple GET request to the following URL:

https://www.googleapis.com/oauth2/v1/userinfo?alt=json&access_token=YOUR_GOOGLE_TOKEN

The response differs based on the given scope on the first login step. Mine was set to the below:

https://www.googleapis.com/auth/plus.me https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email

#google #login_with_google #oauth #scope #userinfo #oauth2

Move the first letter of each word to the end of it, then add "ay" to the end of the word. Leave punctuation marks untouched.

Examples:

pig_it('Pig latin is cool') # igPay atinlay siay oolcay
pig_it('Hello world !')     # elloHay orldway !

How to find the query associated with a queryset in Django ORM?

Sometime you want to know how a Django ORM makes our queries execute or what is the corresponding SQL of the code you are writing. This is very strightforward. Youn can get str of any queryset.query to get the sql.

You have a model called Event. For getting all records, you will write something like Event.objects.all(), then do str(queryset.query)

>>> queryset = Event.objects.all()
>>> str(queryset.query)
SELECT "events_event"."id", "events_event"."epic_id",
    "events_event"."details", "events_event"."years_ago"
    FROM "events_event"

Example 2:

>>> queryset = Event.objects.filter(years_ago__gt=5)
>>> str(queryset.query)
SELECT "events_event"."id", "events_event"."epic_id", "events_event"."details",
"events_event"."years_ago" FROM "events_event"
WHERE "events_event"."years_ago" > 5

How to convert ByteArray to PDF and then upload it via jQuery?

var docData = [ yourByteArray ];
 var blob = new Blob([new Uint8Array(docData)], { type: 'application/pdf' });

 // Now create form to upload the file
 var formData = new FormData();
 formData.append("file", blob);

 // Let's now upload the file
 $.ajax({
         type: 'POST',
         url: 'https://www.YOUR-UPLOAD-FILE-ENDPOINT.com/storage',
         beforeSend: request => set_ajax_headers(request),
         data: formData,
         processData: false,
         contentType: false
     }).done(function(data) {
         console.log('File is uploaded!');
     });

NOTE: function set_ajax_headers is a function that sets headers on the given request.

Write a function that when given a URL as a string, parses out just the domain name and returns it as a string. For example:

domain_name("http://github.com/carbonfive/raygun") == "github" 
domain_name("http://www.zombie-bites.com") == "zombie-bites"
domain_name("https://www.cnet.com") == "cnet"

#python #codewars

def domain_name(url):
    return url.split("//")[-1].split("www.")[-1].split(".")[0]

MongoDB server Load Average: 0.5 (It can reach 16)
Database Size: 100GB (It is compressed in MySQL it reaches 300 GB in size!)
Req/Sec: 500

Our server seems hungry for more requests and more data.

You are given a node that is the beginning of a linked list. This list always contains a tail and a loop.

Your objective is to determine the length of the loop.

For example in the following picture the tail's size is 3 and the loop size is 11:

# Use the `next' attribute to get the following node

node.next

Note: do NOT mutate the nodes!

#python #codewars

Sample Tests:

# Make a short chain with a loop of 3
node1 = Node()
node2 = Node()
node3 = Node()
node4 = Node()
node1.next = node2
node2.next = node3
node3.next = node4
node4.next = node2
Test.assert_equals(loop_size(node1), 3, 'Loop size of 3 expected')

# Make a longer chain with a loop of 29
nodes = [Node() for _ in xrange(50)]
for node, next_node in zip(nodes, nodes[1:]):
    node.next = next_node
nodes[49].next = nodes[21]
Test.assert_equals(loop_size(nodes[0]), 29, 'Loop size of 29 expected')

# Make a very long chain with a loop of 1087
chain = create_chain(3904, 1087)
Test.assert_equals(loop_size(chain), 1087, 'Loop size of 1087 expected')
