Any time that a row ID (oddly placed in column 8, i.e. row[7]) is repeated after the first instance, I want to write those rows into a second file. The code I'm using is extremely slow -- it's a 40-column CSV with about a million rows. This is what I have:

Our Rubberduck open-source VBE add-in project is coming along nicely. One of the main features we're going to be implementing in the next release, is code inspections.
I started by defining an abstraction:
namespace Rubberduck.Inspections
{
/// <summary>
/// An interface that abstracts ...
my objective is to create a Windows Forms program in C++/CLI using Visual Studio 2012. The program should allow a user to enter a number in a text box, and then button1 click basically manipulates a label and textbox, displaying whether the guess is either too high(cold, blue) or warm(red). For...

I'm writing an AdBlocker and it modify browser native to block DHTML effectively, example block Anti-AdBlock.
So I really want to override innerHTML, outerHTML, lenght, width, height using javascript, find a way to get those function arguments[x] to compare, if there is ad words then I will skip...
Here's the problem statement from Minimum Scalar Product
You are given two vectors v1=(x1,x2,...,xn) and v2=(y1,y2,...,yn). The scalar product of these vectors is a single number, calculated as x1y1+x2y2+...+xnyn.
Suppose you are allowed to permute the coordinates of each vector as you wish. ...
I have a question. I need to write a program which will find a prime number, greater than the given n. I wrote the below code, which, I think, works good:
#include <stdio.h>
int isPrime(int n)
{
int i,j=0;
for(i=1; i<=n; i++)
{
if(n%i == 0)
j++;
}
if(j ==...
I have prepared an implementation of sort_by_keys filter
{% for donation in donations|sort_by_keys:'date,-value' %}
<img src="{{ donation.stamp_img_url }}" />
{% endfor %}
example data:
donations = [

date: '29-07-2014',
value: 150,
},
{
date: '07-10-2...
As the first step for writing a Morse code practice program, I thought I'd start with the very simplest step of a text-based Morse code translator. This simple program reads lines from stdin and emits them as a text-based representation of the Morse code equivalent. Any character that doesn't h...
I'm relatively new to NodeJS and express, and I've recently run into the pyramid of doom while doing stuff that requires multiple steps.
I've found that promises are very promising indeed. But I've definitely would love some opinions on various aspects of my approach to routes as a whole.

Problem
To figure out if any anagram of the string can be a palindrome or not.
Idea
It relies on two observations.
Frequency of every character in the string is even, if length of the string is even.
Frequency of every character in the string is even except for one character, who frequen...i need to write a program that reads a sequence of integers and determines if the sequence is alternating.An alternating sequence is a sequence of numbers in which every number should be greater or smaller than the one before it according to the base alternation. for example 1 5 4 8 2 10 is alter...
Natural merge sort is a modification of merge sort that sacrifices O(N) to actually build a list of "runs" that may be defined as monotonically increasing or strictly decreasing contiguous subsequences in the input array. After the run queue is established, the algorithm repeatively pops two runs...
I want to reverse string.
If the string begins with a "'" the whole string should be reversed.
Ex:
"'Hello you"
-> uoy olleH
Hello you
ello you
llo you
lo you
o you
you
you
ou
u
If there's no "'" the string should be reversed word by word. Ex:"Hello you"
-> olleH
Hello
ello
llo

Learning Haskell on my own. On lecture 5 of CIS194
I feel I am over-complicating things, and that there should be a succinct way to achieve this - perhaps using concepts I have not learnt - or some prelude function I have missed out on.
Thankful for any pointers on how I can improve (also on t...
I aim to create a few primitives for creating AES256-then-HMACSHA256 secured session state through cookies.
What I've considered:
HMAC instead of plain sha to avoid hash extension attacks
input validation from the programmer
AES in CBC mode, because we're supporting more than 128 bits of data

I'm creating a small App and decided to write my own DAO for learning etc.
At the moment its in one big file, which i really don't like. COuld you give me some tips on how:
you would separate this into smaller classes and use abstraction, inheritance etc?
how i can update the CRUD functions(th...
