And, as they say: ‘Don’t feed the trolls’ – well, i’m about to do exactly that: feed the trolls at work who love to rag on about how awful obj-c is! So here i go, foolishly treading where no sensible...

Don't Overload #nil?
There’s a popular post on Hacker News about writing confident code by, among other things, overloading Object#nil? and returning “null objects†instead of nil itself.DO NOT DO THIS.In Ruby, all objects (except nil itself) coerce to the boolean value true. Your object will be nil and true at the same time. Bad things will happen. Your coworkers will cry. Sad people from around the world will ask bewildering questions on your mailing list.Here’s what happen...

Read white space with scanf()
Usually, when we want to enter string with white spaces in C, we need to call gets() or fgets(0 method. We usually will not use scanf(0 or fscanf() because they cannot accept white spaces when scan user inputs. But when we specify the format in scanf() function, we may read strings with white space. the code section below illustrate this: #include <stdio.h> int main(int argc,char **argv){ char name[30]; fprintf(stdout,"Please en...
