Recently edited code

Isn't it somwhat misleading to show Recently Edited Java Code and Recently Edited C Code?

Spinoza1111 21:41, 5 June 2006 (CDT)

Feel free to update the main page however you see fit! We could add more languages or anything really... When I made the main page I just wanted to let people know what code is new and being worked on. -Nostromo 09:11, 6 June 2006 (CDT)

C# / VB

Very interesting. Thanks for creating this. Do you want or will you stock C Sharp or Visual Basic code?

Edward G. Nilges, author of <shamelessPlug>Build Your Own .Net Language and Compiler (Apress 2004)</shamelessPlug>

Hi Edward. Yeah, we can add all types of languages. Feel free to build whatever you'd like to see. -Nostromo 09:11, 6 June 2006 (CDT)

Copyright

I just discovered that site by chance from wikipedia:OCaml. I like it. I think it would be nice to have a way to contact the managers/admins of the project, and know a little more about who they are. Is the wiki source distributed under some kind of very flexible license? I don't want to annoy programmers who would copy-paste some code into their programs, it's more about granting the right of cloning the web site in case it is not maintained anymore or something like that. --Martin 05:38, 24 June 2006 (CDT)

Hi Martin. I haven't selected a license yet -- mainly because I'm not a lawyer.  :-) I was thinking either Public Domain or GPL -- but really it's up to what the community thinks is best. The issue I'm mainly concerned with is that I want code from open source projects of all types to be available, which all have their own governing license. That means that the license would depend on the code that is submitted. (What happens when that code evolves is still an open question.) However, any license we as a community choose should be open to complete cloning / redundancy for back-up purposes, etc. Let me know your thoughts! -WikiSysop 12:05, 27 June 2006 (CDT)

Hi All. I've just a question. Can I use a class from this site in my open source project? My open source project needs no GPL license, I need a free code and eventually I'll add some modification to the current implementation of the class. let me know -g.migliavacca 16:36, 22 May 2007 (CDT)

Hello g.migliavacca. All of the code on this wiki is available under the GFDL (full text of the licence), a copyleft licensing scheme, meaning that anyone may use, modify and distribute it, but the resulting work which they distribute must also be 'copylefted'. Hope this (and the links) help. Cheers. --Why My Fleece? 18:52, 22 May 2007 (CDT)

Web Programming

Great site! I hope it will grow and become even better! However - as I'm mainly a web programmer I miss JavaScript and VBScript. I would gladly contribute with loads and loads of functions in those languages. --Megalobrainiac 02:14, 26 June 2006 (CDT)

I too would like to see more web programing and scripting languages. I'm trying to bring in as much content as possible, so keep checking back -- and feel free to add your favorite functions! -WikiSysop 12:05, 27 June 2006 (CDT)

VB.net

Am I allowed to contribute code in VB.net ? Lcarsdata 15:22, 15 February 2007 (CST)

Please do! Contribute in any way you feel is appropriate. We even have some 'recipes' for non-languages, like XML. -Nostromo 15:47, 15 February 2007 (CST)

Full classes

This is fantastic, I've been thinking of doing something like this for quite a while now, glad I found this wiki first.

One thought (for now): It would be nice if, at least for java, every snippet was entered as a full class or at least method. Java has very little overhead for this, and it really leads to ease of use as plug-in code and reusability.

After looking at it a bit more, I realize that you are really targeting smaller code snips. My ideal would be more along a library--is there room for both styles on there? (I put an XML class I wrote in the Java area as an example--what do you think?)

Perhaps a new category tag could be used to indicate a fully-formed library style class, or a snip tag to indicate code that is not?

Also, a summary of categories at the bottom of each edit page with a line on how to use them might help--It took me a while to figure out how to do the whole category thing. Added groovy category as a test...

Why not a merger

Having more than one competing site which provides a wiki code repository makes picking and contributing to one difficult for new users such as myself. Moreover, I'm disturbed by an apparent lack of discourse about a possible merger among such sites, firstly of Code Codex and Rosetta Code. Such a merger of such sites is a highly warranted for several obvious reasons. I hope you won't let personal pride (if any), or trivial code licensing issues, or manageable technical issues come in the way of a better unified future for all. I look forward to continued discussion with regards to this, until compromise and consensus has been achieved, and such non-trivial sites have been merged into one. --Borg 01:06, 31 March 2007 (CDT)

Truth be told, I have no problem if CC includes RC code with attribution. However, I'm not sure that a merger is the best idea, because I've had a different vision of what I want to make Rosetta Code than what I've seen of CC. RC is intended as a learning tool (for me as much as anyone), and a way to increase general knowledge of programming and programming languages. Eventually, I want to see it blossom into an encyclopedia for programmers.
However, I'm not totally adverse to the idea of a merger. If the CodeCodex admins are interested in that, they should send me an email. --Short Circuit 09:14, 31 March 2007 (CDT)
I can understand a merger possibly being less than ideal when there is a serious uncompromisable difference in the site's vision, such as say with LiteratePrograms. However, I personally don't see a big difference in visions of CC and RC. What is the difference as per you? --Borg 12:01, 31 March 2007 (CDT)
Hi all -- thanks for brining this discussion here. While I'm certainly not opposed to merging projects at some point, I think I agree with Short Circuit for the time being. The difference in vision, as I understand it, is that Rosetta Code is more focused on showing similarities between languages on common tasks. While that's possible on CodeCodex, it's less of a focus. For example, we have code on CodeCodex that only really makes sense in one language, such as JavaScript or VBA. I think the vision long-term for CodeCodex is to be a code clearing house, while RC is more focused on common tasks across languages as a method for learning different syntaxes. (Please correct me if I'm off here SC -- I certainly don't want to mischaracterize your great project.)
Also, I'm not sure of the benefits of having only one player in this space this early in the game. Since both CC and RC have lenient licenses, content can flow back and forth freely as both projects see fit. -Nostromo 10:09, 2 April 2007 (CDT)

CAPTCHA

Your CAPTCHA implementation is a bit intrusive. On my site, I use these settings:

Once we identified and blocked the users that had been created by spambots, we ceased getting spam edits, so these settings seem alright. --Short Circuit 00:51, 17 February 2009 (EST)
