Best JavaScript compressor [closed]
...
Packer has an option to 'base62 encode' off - and for jQuery it compresses smaller than yui after gzip. This is because jquery uses 'eval' and 'with' which prevents 'safe' compressors from doing certain compressions, but packer ignores them. Not safe...
Simultaneously merge multiple data.frames in a list
...using the tidyverse packages. For comparison purposes below, you'll find a base R version using the same sample dataset.
1) Join them with reduce from the purrr package:
The purrr package provides a reduce function which has a concise syntax:

How to list the contents of a package using YUM?
...
@dimadima: The question was for yum (= RHEL based systems) which uses rpm as native packet manager (Red Hat Packet Manager). If the OP would be on a debian/ubuntu/.. system, dpkg would be the way to go, since it is the backend to apt.

Determining complexity for recursive functions (Big O notation)
...;
}
This function is being called recursively n times before reaching the base case so its O(n), often called linear.
int recursiveFun2(int n)
{
if (n <= 0)
return 1;
else
return 1 + recursiveFun2(n-5);
}
This function is called n-5 for each time, so we deduct five from...
Initial bytes incorrect after Java AES/CBC decryption
...g this work due to missing some information like, forgetting to convert to Base64, initialization vectors, character set, etc. So I thought of making a fully functional code.
Hope this will be useful to you all:
To compile you need additional Apache Commons Codec jar, which is available here:

How to concatenate two numbers in javascript?
...ut strings, right? Yes there is.
For any two numbers, a and b, with any base B. We are going to multiply a by base B to the power of length b (using log base of b then flooring it to get the nearest whole number then adding 1 to it) then adding b.
So now our code looks like this:
a * Math.p...

Round to 5 (or other number) in Python
...ndard function in Python, but this works for me:
Python 2
def myround(x, base=5):
return int(base * round(float(x)/base))
Python3
def myround(x, base=5):
return base * round(x/base)
It is easy to see why the above works. You want to make sure that your number divided by 5 is an integ...
Difference between abstract class and interface in Python
... methods and attributes on that object.
In Python, we can use an abstract base class to define and enforce an interface.
Using an Abstract Base Class
For example, say we want to use one of the abstract base classes from the collections module:
import collections
class MySet(collections.Set):
