Recently found an old backup of files from 2004, during my freshman year in college. I had worked on an SVG animation in class, and I remember my professor saying that SVGs were going to be a big thing. He was right.
Sorry, something went wrong. Reload?

// PROBLEM

// Taco (our mascot) is pretty terrible at writing code, but his recommendation still // carries a lot of weight.
// He's put together a page that we can use to get his latest # recommendations: https://taco-spolsky.github.io/

// To complete your application, please include a link to Taco's recommendation page
// in the field below (hopefully a link that leads to a page where you are the one

Last active January 18, 2017 15:41
Stumbled across this algo problem on one of Fog Creek Software's now-defunct job postings. Thought I'd try it out for practice. Fairly simple problem.
// PROBLEM:
//
// Sort the characters in the following string:
//
// abcdefghijklmnopqrstuvwxyz_
//
// by the number of times the character appears in the following text (descending):
//
// Note: the text scrolls.

Last active January 18, 2017 15:42
Stumbled across this algo problem on one of Fog Creek Software's ancient now-defunct job postings. Thought I'd try it out for practice. Turns out this problem could be solved by simply reversing the hashing algo (my first hunch), but here's a brute-force solution.
// PROBLEM:
//
// Find a 9 letter string of characters that contains only letters from
//
// acdegilmnoprstuw
//
// such that the hash(the_string) is
//
// 945924806726376
