First thing to comment on after copying and pasting into my IDE, the following line gives a warning:
int size = vec_input.size();
Implicit conversion loses integer precision: 'size_type' (aka 'unsigned long') to 'int'
Apparently, the size() method of Vector returns an unsigned long, and...

I am the half-robot side of syb0rg that will be posting the recent answers of Code Review to the CR Answers chatroom. This is simply a place where you can post your feature requests.
Implementation time will depend on many variables, such as the complexity of the ...

Comment on (recently) (self) deleted posts
I've occasionally had the situation where I'm trying to explain something to a new user about the site - new post review or just habitual refresh of the front page newest, or watching the chat room feed.
My comment is about how the question doesn't fit...
This is a sanitizing function , I wanted to know if this function is secure enough?
public function clean( $input, $fordb = true ) {
global $db;
//is it an array?
if( is_array( $input ) ) {
//yes it is! let's clean each item individually.

Realtime and smarter feeds
Many processes in Stack Exchange are cached, or have delays, that enable the higher performance of the site.
I propose that these caches are selectively removed for 30K users, and that feeds become personalized and more "real time". For example:

I'm practicing templates from a not so well written C++ book and I receive the following compiler errors respectively, "error C4430: missing type specifier - int assumed. Note: C++ does not support default-int" and "error C2143: syntax error : missing ',' before '<'". Both refer me to line 10.

I recently created a gem for jekyll plugin to create some csv files. I put a little more effort into it and tried to make it something that other's might be able to use. I'm a little lost on how to test a jekyll gem and don't often use jekyll. I want to make the code less fragile and could use so...

Most of the reviewers/answerers here should be familiar enough with Ctrl+K and Home,Shift+▼,Del keystroke combinations that an edit to provide some readability without losing the original content of the code submitted should supercede the site policy of not modifying the OP's original code.

I've written a MySQL class that handles sanitization of different data types. The reason I used this (and not prepared statements) is because this can be more dynamic.
Prepared statmenets only supports four data-types:
Integer
Double
String
Blob
This limits functionality and it doesn't all...
Shamir's Secret Sharing scheme essentially splits a secret into n parts, at least k of which are needed to recover it. I'm using that to encrypt/decrypt arbitrary files (it's part of a college project). Here's a rough idea of what I'm doing:
Take a file, and read N bytes. Treat those bytes as a...

The basic Idea would be to exchange the node's inorder successor value with node value . Now the node to be deleted is
case 1.Leaf node
case 2.A node with one right child(inorder successor couldn't have a left child else that would be the inorder successor value)

I have written a program in C to do the following:

See this this question for background. This is a live filter where results are filtered as you type. I've taken into account Kerri's answer and expanded on her recommendation.

Why do Swift questions get marked as duplicates of Objective-C questions?
Swift is attractive to new developers. A new developer may not be at a level to understand Objective-C syntax and may be asking a valid Swift question. For it to be marked as a duplicate of an Objective-C question is unfai...
