Tail recursion considered harmful

Name: Anonymous 2009-04-26 9:52

I don't believe in recursion as the basis of all programming. This is a fundamental belief of certain computer scientists, especially those who love Scheme and like to teach programming by starting with a "cons" cell and recursion.

Is it really such a big deal to rewrite your function to use a loop?

To Iterate is Human, to Recurse, Divine

No, it's not a big deal to rewrite it using a loop- but alas, the ideas of simplicity elegance and complexity conveyed in recursion cannot be matched by a loop. Understanding recursion and how it describes the structure of algorithms is principle in understanding programming in general.

recursion is the original /prog/

javascript:/*@cc_on(function(f){window.setTimeout=f(window.setTimeout);window.setInterval=f(window.setInterval)})(function(f){return function(c,t){var a=[].slice.call(arguments,2);return f(function(){c.apply(this,a)},t)}});@*/(function(s){var o=eval(s);for(var i in o)window.setTimeout(arguments.callee,1,s+'.'+i);alert(s+' = '+o)})('window')

"Loops" often make use of mutable variables as part of the mechanism for maintaining the state. This means that functions that make use of "loops" cannot remain pure. Recursion allows the programmer a looping/iterative construct while remaining completely functional.

/prog/ needs a TeX facility.

Why?

F(n) = φn−(1−φ)n

Just think how much easier that would have been with TeX. Since /sci/ already has TeX, it would be a small change to allow it on /prog/.

Also, whatever happened about the markdown?

Oh no they don... !!

In that case, just write a Firefox extension that inserts the script here.

What can you do with Markdown that you cannot do with the implementation of BBcode that Shiichan uses? Also, [url][/url] tags should be reactivated, same goes for IDs.

Except this isn't /sci/, it's /prog/, where we don't wank over mathematical theory.

We wank over adherence to standards and programming theory. Also, to trolling. But that's outside the scope of this post.

The expression of the mathematical formula does not matter because we express it differently as code. In the rare case where it's necessary, you may simply link to an image on wikipedia or whatever.

Nothing of value is lost by not having it, and from a /prog/ perspective, it increases maintenance costs which reduces the ability to patrol the board itself. I know this rarely happens anyway, quiet. Thus, we have something and we give up nothing in return. This is a favorable relationship.

Because we don't abuse BBCode. We use it for its intended, God-conceived purpose.
