I came across the question: Single-page personal portfolio website It has an answer, that doesn't review the code at all. It only comments: […] I can tell you there is not many things you can really cut in order to make the code more tidy without resorting to frameworks. Inevitably as this ...

I've researched this morning how to use Google Analytics to track outbound page views. However, I think the implementation might be a bit difficult on our website (as we have hundreds of outbound links) Here's what google recommends. /** * Function that tracks a click on an outbound link i...

I've recently put together a library for working with Crypto in Go. I did not roll my own, I'm relying on stdlib for the core parts of this, but I would still like to get this reviewed by some experts in case I've done something horrific. If you're interested and want to view this in a more pal...

This program should convert a file containing Mana, Hashcat or John the Ripper NTLMv1 hashes to another file containing Hashcat or John the Ripper hashes. Do you have any suggestions on how to make the code cleaner? The hash format selection code feels kinda dirty. #!/usr/bin/env python3 # Take...

Trying to find way to do this with only one pass through the array, so I won't run a sort on it and take arr[0..1]. Not sure how to make it look better: def LowestSecondLowest(arr) lowest,second_lowest = nil,nil arr.each do |n| if second_lowest.nil? second_lowest=n elsif lowe...

Very simple code, works fine. I'm mainly interested in the method I used to count lines. I thought about using fgetc, but I'm not even sure if it'd read the newline character, and I think it's slower too. #include <stdio.h> #include <stdlib.h> #define MAX_SIZE 1000 int main(void){ FILE *in_...

I am especially concerned about: Correctness: Does my algorithm always output the correct answer given a correct input? Readability: Is my algorithm easy to understand for an experienced Ruby programmer (or, in other words: how many WTFs does a experienced Ruby programmer say while reading my c...

The purpose of my code here is to play a part in genome sequencing analysis, and while functional it takes days to run, so I am looking for any way I can improve speed.
