Write a program or function that takes in a nonempty single-line string. The string will either be zero or more spaces followed by one period (a particle), such as . or ., or the string will be a sequence of one or more alternating forward and back slashes (a wave) that could start with ...
Your task is to, given an image, compress it to 100000 bytes or less while still preserving the image's quality as much as you can.
Rules:
No cheating/loopholes.
Your code must not be optimized to work best only on the test set of images, but rather produce a good output in general.

Task
Your task is to write a program that will output ASCII boxes at the locations specified by the input.
Input
You will be given a list of numbers. The format here is a bit flexible, in that you can use any deliminator you want (e.g. 1,2,3,4, 1 2 3 4, [1,2,3,4]). The list is in groups of 4 a...
This task is part of the First Periodic Premier Programming Puzzle Push.
You get a hierarchy of items in the following format:

Introduction
As some of you may know, URLs actually have a list of characters that do special things. For example, the / character separates parts of the URL, and the ?, &, and = characters are used to pass query parameters to the server. In fact, there is a bunch of characters with special func...
C, 69 bytes
p;f(char*s){p=s[strlen(s)-1]^46;p^=p?93:3022856;printf("%s%s",s,&p);}
This requires a little-endian machine, and output to a terminal that support ASCII escape codes.
p=s[strlen(s)-1]^46 grabs the last ASCII code of the input string, and XORs it with the ASCII code of a dot.
p^=p...
I want to replace a character with its hex literal. For example before regex:
h
After regex:
0x68
I'm trying this:
s/\([a-z]\)/\=printf("%#02x", submatch(0))/
But this replaces it with
00
What am I doing wrong? Is this even possible?
