What stirs your rage, /prog/?

Mine are people who do this on C-like languages:
if(numbers==NULL)
{
numbers=temp;
numbers->next=NULL;
}
else
{
temp2=numbers;
while(temp2!=NULL)
{
var=temp2;
temp2=temp2->next;
}
temp2=temp;
var->next=temp2;
temp2->next=NULL;
}

No spaces between operators.
Opening brace on lines by themselve.
Else statement not a continuation of the if-statement it belongs to
Terse variable.
camelCase

Else statement not a continuation of the if-statement it belongs to

Do you mean:
if (predicate){
// something
} else {
// alternate
}

I fucking hate when people do this. It's one of my programming pet-peeves. I scan the block level by line, if you put else after a brace it's harder to see and it just looks retarded. The only time you can put anything after a brace is in:
do {
// something
} while (condition)
