Challenge
Suppose you have a list of numbers, and a target value. Find the set of all combinations of your numbers which add up to the target value, returning them as list indeces.
Input and Output
The input will take a list of numbers (not necessarily unique) and a target summation number. Th...
I almost dupe voted that question (before I started answering) and then I remembered that my dupe-votes are actually hammers now. I almost forgot because I've never used it before :P
@user202729 It does really look like a math function. It used to look kind of exponential because I was getting increasingly active but then I became decreasingly active (for multiple reasons) so it looks kind of like a sigmoid :P
I got 3k rep in like a month before I got a promotion, then really 0 rep until I got fired, then 3k rep in like another month before I got a job again, then ... really 0 rep
Yeah, I guess the two things I hate about Swift are Xcode and the fact that there's a major version released every year, so most of the documentation on a thing I want to search up is outdated
I think Apple purposely does this so that it hinders people making iOS apps etc. on non-Apple products
@Downgoat Why would you not use the latest version of any programming language ever, except when working on legacy software and/or needing to support IE8?

@Pavel Updating software is expensive in terms of man-hours. Don't fix what isn't broken, etc.
You know what a palinedrome, a prime and a date is.
Your task is to list all dates in 100 thousands of years that fulfill
all three characteristics.
Nevermind anything but the numbers, use the following formats: YYYYMMDD and YYYYYMMDD.
Dates between 0000-01-01 and 9999-12-31 should be p...
In an advanced university course on computer science and problem solving, one of my fellow students asked for a solution to a home exam on one of the Stack Exchange sites. The question he asked is taken directly from the exam without modification also stating that this is practice question for th...
I have n pairs of numbers: { p[1], s[1] }, { p[2], s[2] }, ... , { p[n], s[n] }
Where p[i] is integer greater than 1; s[i] is integer : 0 <= s[i] <= p[i]
Is there any way to determine minimum positive integer a , such that for each pair :
( s[i] + a ) mod p[i] != 0
Anything better than brute...

New way of stopping WW from changing his name/profile: Everytime he does it, he loses 100 rep if the community asks him to change. See how long it takes to get a decent picture and name :P
@quartata I just wanted to say sorry for what happened yesterday. After looking into it I now see why that term is offensive. Thank you for calling me out.
One of PPCG's oldest rules, mentioned in What topics can I ask about here?, is that all answers to challenge questions must:

I think it should be added to the standard loopholes. Posting an ungolfed answer to a code golf, then claiming its a 'baseline' solution isn't allowed, why should answers that deliberately get a bad score?

@Doorknob Out of curiosity, is your profile still accurate about your age? 'Cause if so, and "Member for 5 years, 11 months", that means you were about 10 when you joined?

Jewish joke (not Nazi propaganda): Two Jews arrive to Ellis Island. They see a sign offering money in exchange for letting oneself be baptised. One is willing, but the other reluctant. The willing goes in. Long time passes. He comes back out. The reluctant: "Nu, did you get the money?" The other: "Oh you Jews — all you think about is money!"

Challenge
Basically do what the title says
Method
Given a positive integer 1 <= N <= 100000000000 through one of our standard input methods, multiply every digit together, ignoring zeroes.
Ex: Take a number, say 361218402:
3 * 6 = 18
18 * 1 = 18
18 * 2 = 36
36 * 1 = 36
36 * 8 = 288
288 * 4...
