I saw a simple method to calculate Log2(N), where N is the power of 2:
unsigned int Log2(unsigned int N)
{
unsigned int n = 0;
while (N >>= 1)
{
++n;
}
return n;
}
It would be not likely very necessary, but I try to improve it in a simple way, the idea comes from bi...
Please see this link to see original question and code:
I tested that code to see if I could implement something similar I was working.
Manually went through code. Saved M so I can read it again and continue.
M <- read.csv("test-2016-12-30.csv")
KEYS = c("ShortFileName")
VAL = c("scanDate","Co...
I'm looking to learn how to write efficient Haskell code. This snippet works, but the run time is slow. How can I write faster Haskell code?
input: maxPrice = 7
input: vendorsDelivery = [5, 4, 2, 3]
input: vendorsProducts = [[1, 1, 1],[3, -1, 3],[-1, 2, 2],[5, -1, -1]]
output: [1,2] (fastest...
I revised the code in here because I wanted to get an square magic 3x3.
It works, but it's slow. Any suggestions on speeding up the code?

I have a Slack bot that takes a stream of messages and the idea is that if 3 different users repeat the same message, the bot will also mime that message.
I am just beginning with RXJS and I am trying to figure out the correct, most idiomatic way to refactor the following code. Is it even possi...
I have code for a discord music bot, but I don't understand why when I try to addstaff. I get

What is a more pythonic way to write a try/except clause with a return value?
Example A, is shorter, but I don't like the fact that the method seems to have a "dangling" return statement (visually the method just drops off the end).
Example B, is longer, but seems to be more clear that the meth...
This code is my answer to question 7 of Real World Haskell, chapter 3's review section at the end.
intersperse :: a -> [[a]] -> [a]
intersperse _ [x] = x
intersperse sep (x:xs) = x ++ sep : (intersperse sep xs)
intersperse _ [] = []
The code satisfies all of the conditions of the question, but...
I have a function in python where I want the reverse complement of a DNA string.
This is what I have now:
def inversComplement(input):
output = ''
for letter in input:
letter = letter.upper()
if letter == 'A':
output += 'T'
elif letter == 'T':

My program can be called like this:
FakeDpi someInteger someExecutable [parametersForSomeExecutable]
For example:
FakeDpi 120 "C:\Program Files (x86)\...\excel.exe" /X "C:\Users\...\myFile.xlsx"
should result in
dpi = 120
exe = C:\Program Files (x86)\...\excel.exe
args = /X "C:\Users\...\m...
I need to TAB through a combination of ComboBox(es) and cells in my worksheet. I have written the following code to jump from a ComboBox to a ComboBox:
Private Sub ComboBox1_KeyDown (ByValKeyCode As MSForms.ReturnInteger, ByVal Shift as Integer)
If KeyCode = 9 Then ComboBox2.Activate
End Sub

I'm a noob coder, learning Javascript. I'm trying to make a text adventure game, which is starting to take shape. But I've hit a brick wall when it comes to making the text commands interactive. For instance, I'm working on 'get'/'take' items. Obviously the command would followed by the item (for...
I use revealing module pattern to give my JavaScript code a little structure, my question is about proper naming, I have something like this:

Because I have writing more multithreaded C++14 code lately, I've developed some tools that help me make sure that my threads are all working as intended. In the real code, it's often difficult to detect race conditions or unintended sequence dependencies among threads, so I have found that temp...
I wrote an entab program which needs to replace every \$n\$ spaces with 1 tab. I picked \$n\$ to be 4, so every 4 spaces should be 1 tab. I have a feeling that my code is far too complicated than it should be, and the logic I made it with could be much simpler.
The logic of the code:
Note: \$n\...
Some I am trying to develop a program in python with tkinter and pyserial with the objective to control the color of a RGB LED connected to the arduino. The code is functional, but with a few problems. Here is the code:
Arduino.
