This is a fairly simple code golf challenge. Your program, given an ASCII string, is to parse that string into two strings, which it will evaluate. If the second string is "later" than the first one, it will return a 1, if it is "earlier" than the first one, it will return a -1, and if they are t...
Symbolic differentiation of polynomials
Longtime lurker, but I've just started submitting to challenges and I'd like some help developing one of my own.
Task
Write a program that takes in a polynomial in x from stdin (order(p)>1) and differentiates it. The input polynomial will be a string of ...
Write a few lines of Python code, X, that does not reference any global variables, such that
def method():
X
print(a)
method()
prints 1 but
def method():
X
X
print(a)
method()
prints 2.
I found an old post on Jon Skeet's blog that pointed out a puzzle from a tweet by Vladimir Reshetnikov:
C# quiz: write a valid C# program containing a sequence of three tokens ? null : that remains valid after we remove the null.
Note that the wording "three tokens" is important: "? null :"...
64 bit weaving
code-golf
Input
Two integers:
A non-negative integer W in the range 0 to 2^64-1, specifying the weave.
A positive integer S in the range 1 to 255, specifying the side length.
Output
An S by S ASCII representation of the requested weave (S newline separated strings of S ch...
Challenge
Given the equation of a line and the coordinates of the vertices of a shape, output the coordinates of the shape when reflected across the given line.
Further Information
The line's equation will be given with a y and an x separated by an equals sign (there may not always be a y and ...
(A few related meta questions)
I know of a couple logic puzzles that I think would make good questions for this site. However, they are not original to me. I got them from this puzzle book. With proper source attribution, can I base challenges on them?
Considerations for:

Background
PICASCII is a neat tool that converts images into ASCII art.
It achieves different degrees of brightness by using the following ten ASCII characters:
@#+';:,.`
We'll say that these charxels (character elements) have brightnesses from 1 (at-sign) to 10 (space).
Below, you can see...
