I like anagrams. I like programs that reference their own source code. So this challenge combines them!
Input.
The input to the program could be anything, including letters, numbers, symbols, you name it.
Output.
A truthy value if the input's characters can be rearranged to give the source code, ...
Close the case
NO CasE ShoulD StaY OpeN, ClosE ThE CasE
Given a sentence as input, close every uppercased word at letter i by changing letter -i to upperCase.
Rules:
Every case in a word should be followed up by a case on the mirrored position of the word.
In case the case is in the middle of...
I am wondering If docker could be used to perform this. So I have a website which I want to use as a cloud-storage provider (friends and family).
But what is getting me annoyed is that maybe, some friend uploads a virus, a malicious php executable or something that could harm the root system. I a...
When I was a kid, there was a "really cool" shortcut to count to 100:
1, 2, miss a few, 99, 100
Output the exact string above, in the fewest characters possible, without using these characters: 0, 1, 2, 9

For anyone who has spent a headache trying to understand dir_colors with GNU ls, this may be the post for you!
We're going to ignore parsing LS_COLORS, or matching globs,

Powerful numbers are positive integers such that, when expressed as a prime factorisation:
$$a = p_1^{e_1} \times p_2^{e_2} \times p_3^{e_3} \cdots \times p_k^{e_k}$$
all exponents \$e_1, e_2, ...\$ are greater than or equal to \$2\$. Note that the exponents do not include zero exponents, as exam...
Is it zero- or one- indexed?
code-golf array
Your task is to determine whether some arbitrary programming language has zero-indexed or one-indexed arrays based on sample inputs and outputs
Inputs
An array of integers with at least 2 elements
A positive integer index
The value of the array at th...
I ain't no Fortunate Prime
The primorial \$p_n\#\$ is the product of the first \$n\$ primes. The sequence begins \$2, 6, 30, 210, 2310\$.
A Fortunate number, \$F_n\$, is the smallest integer \$m > 1\$ such that \$p_n\# + m\$ is prime. For example \$F_7 = 19\$ as:
$$p_7\# = 2\times3\times5\times7\...
