When I need a singleton class in my Ruby code (for example, single logger for multiple classes) I usually use code like this:
class Parent_Singleton
@singleton = nil
def self.new
@singleton || (@singleton = super)
end
end
This approach allows me to avoid using the module Singleton (b...

I tried to review this question, once I was done, I tried to click on I'm Done radio button, but I can't (it is disabled). I can only choose No action needed, but I decided to skip instead.
The last first post I reviewed yesterday falls in the same scenario (except I did not skip)
I have implemented Binary_Search in python (I think), and my own method for range objects. I want to know if there is any way to improve this code, here it is:
def findAmountString(string, char):
amount = 0
for n in range(len(string)):
if string[n] == char: amount += 1
return amount
def...
I hope this is the right place for asking this type of question. If not please direct me to the right place.
So we have quiet a big TypeScript codebase at work, where each method resides in its own file. Now in a lot of those methods the variables are often declared all together at the top/beginn...

I have this code which I use to append data to a JSON file. It will be helpful if someone could suggest pointers on:
Reducing file opening and closing
Make the write_json function efficient
and other general pointers. Thanks a lot.

The following code was written with the intent to be as efficient as possible, where efficiency includes speed of execution, memory usage, and lines of code, all in support of the primary design constraint that it can change the payload argument buffer in-place.
In its current state:
It does succ...
The program will read size of free memory partitions and size of processes from a text file and then will try to allocate a memory partition for each process using the first-fit algorithm.
Input Example:
300,600,350,200,750,125
115,500,358,200,375
My code for the implementation:
import sys

My function needs to check if some nested object is empty.
For flat objects, there is no need of recursion, and a very basic function could be the following (inspired to PHP empty):
empty = function (mixedVar) {
var undef
var key
var i
var len
var emptyValues = [unde...

My problem was that scripts I found online for this displayed all the containers, but sinc...
