The ubuntu-bug tool does not support this. It will ask a few questions and send you to a Launchpad page. You should upload/post your patch there.

I'm not sure this would be the right solution. Something like a plugin package manager seems to be better in my eyes. I'll have to think a little bit more about this issue. What are the popular plugins?

Message passing in itself (in the Erlang sense) is neither sufficient nor necessary for concurrent programming. The important part for security is that immutable things are passed between separated domains (processes in Erlang). This ensures that no state is shared. Without message passing transactional memory can achieve similiar effects. I don't want to dig into concurrency at this point though, it is overhyped anyways.

For the argument that polymorphism is the single common property Smalltalks set of properties isn't needed and doesn't contradict it.

Ist 16:9 aber nun wirklich der beste Kompromiss oder gibt es bessere Methoden als "größtmögliche Überlappung"?

Thanks for your comment! I'd say an anonymous function is a first-class function without a name. For a longer explanation some way of introduction has to be chosen and in my opinion this one is short and easy to understand. Can you propose a better introduction?

This makes property 4 nearly paradox, since it can be resolved by violating it. Property 4 is probably useful for formal theory, but useless in practice.

With "higher template magic" i didn't mean "hard to understand", but "it takes too much text at this point". Your explanation is very good, so thank you very much for this extension.

Thanks for your comment. Your argument is good. My argument is that polymorphism is the essence of OOP, because it is the only property all OO languages share. If this is ruled out, there is nothing common between OO languages.

Which means the term is either useless or another definition has to be found. Maybe "implements at least n of the nine properties". Where n is at most 4 to include Simula, the first OO language.

Are you sure? The ActionScript documentation displays polymorphism: http://www.adobe.com/devnet...

Thanks for your comment anyways. I made up the language on the fly and later found that it pretty much is JavaScript. Adding the "var" keywords seems to be enough to make it valid then. :)

I just saw that i did write "OOP is better than other paradigms" and corrected that. Sorry!

That's why there are two warnings at the top of the Wikipedia article. ;)

It's hard to find a definitive reference, because everybody just writes "the well-known principle of locality". For example in the abstract of a paper:
"Object-oriented design (OOD), as introduced by Booch [3], emphasizes the software-engineering principles of locality, encapsulation, and information hiding." http://portal.acm.org/citat...

The citation [3] refers to the book "Software engineering with Ada" by Grady Booch from 1983. Maybe that's the source of "my" principle of locality.

Thanks for your comment! This article is not an "argument for OOP", it is my try to define OOP and consider it necessity. My argument is: If you think the principle of locality is worthwhile, then you want polymorphism in your language, otherwise you have to use an object-framework like gobject. Which means: every programming language should support polymorphism.

Also I didn't declare OOP as the best paradigm, if there even is a "best" one. Personally i think object-oriented and functional are complementary, but we haven't found the sweet spot yet. Maybe i should write a similar article about functional programming?

I'm not good enough with e.g. Haskell to judge its object-orientedness. As far as i know it supports polymorphism, hence it is object-oriented according to my definition. The examples i found online haven't completely convinced me though.

Thanks for your comment, Venkman! I avoided the phrase "functions are values", because i think it confuses the reader. What is a "value"? "Anything that can be assigned to a variable" is an appropriate definition i think. So i took that shortcut instead of talking about values.

Apart from the pub-sub stuff, you could just use ikiwiki.

You can run ikiwiki locally as well as online. There is no tool to provide "realtime preview", but it isn't hard to write a plugin or script to do this.

Isn't it like Googles PageRank? You get credibility by being rated credible by credible people.

I lately stumpled upon Website Baker. It is a simple PHP CMS, but easy to hack if you know a thing or two about PHP. The problem may be the integration part.
