Objective: Crop the image so only the number stays in the image
Problem: Slow Performance
I have code that crops an image.
The image pixels are 0 or 255. There are no values between.
The background is 0 (black)
The Letter/Number is between 0(not-inclusive) - 255 (white)
This code is being us...
At the bottom is my implementation of a segment tree with a sample driver file (Didn't make an update function because I didn't need it for what I was doing).

I need to get the results of the following function:
getScore <- function(history, similarities) {
nh<-ifelse(similarities<0, 6-history,history)
x <- nh*abs(similarities)

x2 <- sum(x, na.rm=TRUE)/sum(abs(similarities[contados]),na.rm=TRUE)

I've written a simple ascii dungeon generator on c++. It works most of the time, but sometimes it only generates one or two rooms. That's the fault of my self-made algorithm. Do you think I can somehow prevent that from happening? And what are your thoughts on the code overall?
Algorithm:

Let's just start at the top. I'll do some basic things that you should have done before posting here. Because they are basic courtesy to the reader. After that, when I still have some energy left I actually may review your code.

Classnames should be PascalCase....
The code below takes in two arguments, 'a path to search' and an 'output file name'. It searches the supplied path (including sub directories) and writes out all files that have the same size as any other files in the path. This will form part of a multi-step process to identify duplicate files...
I often need to switch connection strings and databases (dev/prod) and I need to be able to execute queries with the NOLOCK flag.
For this purpose I create a few utilities that should make this a little bit easier.
The main class is the QueryService that encapsulates the enitre setup process ...

Good morning, fellow coders.
Here you can see a mediocre code of mine where I have fun with four deques, each with a different priority.
Here is how it works: in a while loop I generate a random number between 1 (highest priority) and 4 (lowest priority), and this number tells me in which deque...
I wanted to use System.Timers.Timer for my task but it always runs synchronously. This is why I wrote following class. Question is: is there any bugs or something? It may be enhanced?

I recently wrote this PHP MVC framework. Would like your review.

require 'common.inc.php'; //define constants, auto loading etc

What is a Zombie? Why are Code Reviewers so violent and talking about killing Zombies all the time? And what ammo are they talking about? What is a TS? What does RSA mean?

I would like to create a DDD domain model library, to be used to any client. Where each client will provide default implementation of services.
My solution is something mixing Factory Method Pattern with Singleton:

I'm working on a "nice" crawler that start with one url, and find the other urls to process each page, a kind of "Google" crawler, to index pages.

I have a paper on the definition of (i) available here. I was curious about the simultaneous real numbers associated with the roots of unity, and noticed there was not a routine in R.

Based on previous question, The Code now relied on std::regex for validate and split the input. Also, I removed all duplicates functionality by reading the input and applied conversion in-place.
How can I improve it further.
