:set backspace=indent,eol,start 
This worked for me:
:set backspace=indent,eol,start
I'm not sure exactly what it does but it is listed as a possible solution here and here. I found this line in a vimrc file distributed with Ubuntu where the behavior of the mac "delete" key (otherwise known as the "backspace" key) works as ex...
The Motivation
The desire for a KOTH server has been around for a while. There have been a couple notable meta discussions about it in the past:
Creating an official place to become a King of the Hill tester
How could we run KotHs in a distributed fashion?
By being able to host KOTHs on a se...
Goal
You're playing a computerised chess game. The display is in black and white only and the pixels are chunky. White pixels use a lot power compared to black pixels and you're concerned about your carbon footprint.
Given a square and a piece in chess notation, return the number of white pix...

APL, 9 bytes
{⎕←⍵:∇⍵}⎕
Explanation:
⎕ ⍝ read a number from the keyboard
{⎕←⍵: } ⍝ output it, and if it is true:
∇⍵ ⍝ call the function again with that input
The APL code page is an EBCDIC-based code page used specifically to write programs written in the APL programming language.
== Character set ==
Due to its origins on IBM Selectric Teleprinters, APL symbols have traditionally been represented on the wire using a unique, non-standard character set. In the beginning, there were few terminal devices which could reproduce them—the most popular ones being the Selectric fitted with a specific APL print head. Over time, with the universal use of high-quality graphic display, printing devices and Unicode support, the APL character font problem has largely...

I've seen some code golf languages that still a work in progress (functions being added etc), but they have already been made public and people are posting answers using those languages.
I'd like to know what the standard practice is regarding changes to the language as it's still being polished...

Pyth, 8
u+G!OTsQ
Try it online
This uses Pyth's second mode on reduce, that looks for repeated input then exits.
Explanation
u+G!OTsQ ## Implicit: Q=eval(input())
u sQ ## reduce with 2 arguments, which causes a loop until the reduce gets the
## same argument twice

Stack Exchange automagically detects serial
voting (when one user either
upvotes or downvotes many of another user's posts) and reverses it. In this
challenge, you will implement a very, very simple "serial vote" detector.
Input
The input is a string representing a list of votes. Every group of...
