Theme:
A theme is required for material components to work properly within the application.
Angular Material 2 provides four prebuilt themes:
deeppurple-amber
indigo-pink
pink-bluegrey
purple-green
If you are using Angular CLI, you can import one of the prebuilt themes in style.css.

Let's assume we have a Dogs application, then our model will be a Dog class.
DatabaseReference reference = FirebaseDatabase.getInstance().getReference().child("dogs");
This is how to send a Dog to the database, a new unique dog and set the dog with the key.
String key = reference.push...
Using the dynamic variable %Random%, we can get a random integer from 0 to 32767. For example:
echo %random%
This obviously, returns an integer from 0 to 32767. But sometimes we want it to be in a specific range, say from 1 to 100.
Generating Random Numbers Within Specific Range
The basic me...
Unfortunately, batch does not have a built-in method to generate alphabets, but using %random% and for loop, we can 'generate' alphabets.
This is a simple idea of how this works.
set /a result=(%random%*26/32768)+1
for /f "tokens=%result%" %%I in ("A B C D E F G H I J K L M N O P...

The Boolean operators || and && will "short circuit" and not evaluate the second parameter if the first is true or false respectively. This can be used to write short conditionals like:
var x = 10
x == 10 && alert("x is 10")
x == 10 || alert("x is not 1...
Pseudorandom Distribution
Accorinding to this Stack Overflow answer, user CherryDT pointed out this code:
set /a num=%random% %% 100
does not give a uniform distribution.
The internal dynamic variable %random% does gives a uniform distribution, but the above code will not be a uniformed random...

np.save and np.load provide a easy to use framework for saving and loading of arbitrary sized numpy arrays:
import numpy as np
a = np.random.randint(10,size=(3,3))
np.save('arr', a)
a2 = np.load('arr.npy')
print a2
