When code-golfing there will be times where you need a Hex Dump of your code, usually because you've used unprintable characters. So, why not make a program that Hex Dumps itself?
The Challenge
This challenge is to, given no input, output a Hex Dump of your source code in the following formatti...
To neutralize an array, recursively replace all numbers (not digits!) with zeros and all characters (not strings!) with spaces.
If your language contains a built-in which does all or most of this task, I would appreciate an additional alternative version without it.

Introduction
You have been tasked to write a program that splits a rectangular integer array evenly in half (for whatever reason).
This task is computationally intensive, but luckily you have a dual-core machine to perform the calculations.
To maximize the benefits of parallelism, you decide to ...
It's time for a clock challenge
I'd like you to build me a clock that displays time in this format:
18 ----------
19 --------------------------------------------------
This displays '18:10'. The current hour and the next hour are shown at the front of the line, followed by a space and a numbe...
Do you know that language? answer-chaining
Task:
Your challenge is, given previous submissions and itself as input, output the language that they're written in, in the following format:
Say the first program is in Ruby. It must output 1, because Ruby is the 1st language used in this challenge....
Once upon a time, There was a lord of legendary questions, named Matthew (yep, thats me, and some of you may know me).
Unfortunately, he was previously kicked out from PPCG because the lord of StackExchange, used "age restriction" on him.
Now, he(I) is back, and about to give you a code golf qu...
This is a cops-and-robbers puzzle the robbers' thread can be found here.
Your task will be two write two programs that are anagrams of each other and perform each others inverses. These programs may accept and output as many numbers1 as you wish. If you choose take numbers as character points ...

Detect Failing Castles

One of the interesting aspects of gravity is that you can't just have stuff floating in midair. (As far as I know.)
However, it seems not everyone at the Association of Random Castle Builders is aware of this fact, leading to castles ...
Number that includes the amount of digits of itself
code-golfnumber
Create a number where each digit represents the amount of this digit the number itself contains. Maybe my english is too bad to describe it clearly so here is an example:
8000000010
explanation:
8 -> this number ...
