@Rainbolt should classes go in their own file?

Leaky Nun

@TimmyD You can do this in Vim by pressing <N>~ where <N> is the number of characters you want to toggle the case for.

For example, try typing this in Vim: itesting<ESC>^4~

Rainbolt

@NathanMerrill I prefer one class per file except in rare cases. For example, we had a bunch of auto generated classes that were built from a json structure. I put them all in one file.

Nathan Merrill

if I had two closely related classes, I prefer to put them in the same file

TimmyD

@LeakyNun I use NEdit whenever I'm subjected to *nix.

Q: Return the integers with square digit-sums

Introduction and Credit We all know and love our awesome rules to test whether a number is divisble by 11 or 3, which is just some clever sum over the digits of the number. Now this challenge takes this to a new level, by requiring you to compute the sum of the digits and then checking whether t...

Nathan Merrill

you know, too bad we don't switch the month that gets an extra day. Maybe we should give months an extra day on a rotating basis (January year 0, February year 4, March year 8...)

then people that are born on January 32 have to wait a whopping 48 years before they get another birthday :)

Eᴀsᴛᴇʀʟʏ Iʀᴋ

Maybe we should give up and find a planet where the length of the day is a factor of the length of the solar cycle?

An exact factor. That would be hard to come by

Nathan Merrill

@EᴀsᴛᴇʀʟʏIʀᴋ the problem isn't the lunar cycle, its that our solar cycle isn't divisible by our day cycle
