What those it mean for a code to be called clean? Is it by strictly following the rules, commenting regularly, or neatness in the real sense like arrangements. This may sound stupid... But...

Almost like Jazz Music, if you ask, you can't know, you only have to experience it.

Almost like how you can tell a master orator from a wunnabe talker.

Always a thing of beauty...

It's is elegant, no surprises, a little happiness here and there, it's poetic, actually, let me quote from the "Tao of Programming":

"
A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity.

A program should follow the `Law of Least Astonishment'. What is this law? It is simply that the program should always respond to the user in the way that astonishes him least.

A program, no matter how complex, should act as a single unit. The program should be directed by the logic within rather than by outward appearances.

If the program fails in these requirements, it will be in a state of disorder and confusion. The only way to correct this is to rewrite the program.

10ks... Since I‘ve not gone too far in this programming stuffs, it‘s better I know now, remember that “it‘s easier to train a child than to correct an adult“.
Since dirty codes doesn‘t really mean wrong codes, meaning the program will still function well... most of us may not get it right, a lot programmers write dirty codes maybe due to the way they stared or taught or deadline pressure and maybe because there‘s no penalty for it. I don‘t really understand grammar easily in mathematics and programming class, if anyone will show me example of a dirty coding and example of the corresponding clean code. I‘ll appreciate it...

In that light, the way to learn clean code is to read clean code, and a great place to start is: https://github.com/languages

There, you can select which language you're interested in and read how they attack problems and see what the conventions [idioms] are (as in language styles). Some language like Ruby and Python, folks in does language tale their idioms seriously, deviating from the idiom is considered dirty especially considering there are so many different ways you can write the same thing. (think of it as the English language, you can say "I'm coming, or I am coming", in academia, writing the later is strongly frowned on, you get the point).

But, again to see example of clean code, read clean codes and learn the patterns (and the great thing about Github is that you can ask the folks directly behind the code questions) and of course, see some clean codes here: https://github.com/languages or http://freecode.com/

( I would typically recommend Github more considering how snobby the guys on there are ... which makes them write even cleaner)

@delomos thanks, I think that helps...
And I spent hours reading ur NL posts and googlin ur name and reading your blogs. I think I love your blogs and opinions about things generally... I‘ve been searching and I don‘t really know someone like u exist, I mean an African... I did my permutations, random selections, logical reasoning, tests etc... The end result is void, I mean empty set, no value to return. But here you are... I‘ll somehow like to whatchamacallit... Ummmm... Relate with you.

Or what do you think?

@SoftVersion:
I'm humbled brother, thanks.

As to relating to me, not very sure how you mean?

@delomos, I will explain better in private mail to you. Can you please provide me your e-mail address or somewhere I can private message you. Thanks

@SoftVersion: me {at{ delewrit.es {dot{ com

@delomos and @softversion, Me i like this una dating oh... heehehe. nice work. Thats what this forum's all about. Networking. Keep it up.

@kodewriter lol...
@delomos message sent...

@delomos... Sth wrong wit dat email... delewrit.es.com?

SoftVersion: @delomos... Sth wrong wit dat email... delewrit.es.com?

Not sure how you mean, I got the mail, will be replying shortly. thanks.

@SoftVersion: please send that email to me (at) delewrit.es -- the one I got was from NL PM, not sure how to respond to it from within NL.
