Thanks for you changes to Glass (and many other nodes!), the reorganization is quite nice :) --GregorR 19:36, 12 Jun 2006 (UTC)

You're welcome! I wondered what you thought about my replacing pointers by names, I thought it seemed more intuitive given the context-sensitivity. Also whether I got anything wrong about how the language works.
Next time I do a major edit by pasting into vim, I'll have to remember to :set paste to avoid inserting line breaks. The diffs got all messed up, and I just discovered the author link was broken. --Ørjan 20:04, 12 Jun 2006 (UTC)

Thanks for sorting out a page for me. It's quite generous of you. --Thematrixeatsyou 06:33, 1 Aug 2006 (UTC)

Thanks for creating the numerous Deadfish implementations. --Jonskinner

Thank you for the Puzzlang edits! I hadn't thought of the triangle approach. I will leave in the toroidal geometry, for short minimalist programs (obfuscated Puzzlang?). Daedalus 00:47, 25 February 2009 (UTC)

Some damn impressive work with Slashes! Congrats. What do you think, is it a Turing tarpit? --Keymaker 08:42, 14 May 2009 (UTC)

I hope you'll be even more impressed with what I'm currently designing, in which case the answer will be "yes". :) --Ørjan 15:41, 14 May 2009 (UTC)

The Haskell TM->Geom compiler you added to Geom is ingenious! Awesome work. I had wondered whether the call stack would be sufficient to emulate a two-way tape, but I couldn't work out the details. Tzec 13:04, 1 October 2011 (UTC)

Thanks! I got a lot of experience with that technique during my Underload experiments. :) --Ørjan 21:38, 1 October 2011 (UTC)

Thanks for sorting 0815 page out man, it looks much better now!--Paulo Jorente (talk) 07:39, 11 February 2013 (UTC)

Thank you for straightening me out. I appreciate all the work you do on the Esolang Wiki! --Johnnie (talk) 14:16, 7 February 2014 (UTC) 01:55, 19 November 2014 (UTC)

AAAAAAAAAAAAAA!!!! --Ørjan (talk) 01:59, 19 November 2014 (UTC)

Thanks for your updates to Nanofuck! Orby (talk) 00:52, 27 March 2017 (UTC)

Thank you very much for the formatting help on Micro! That is the first page I've ever created, and I don't really know how to operate the editor yet. Thanks, again! --raddish0 --(this comment by Raddish0 at 20:18, 5 June 2017‎ UTC; please sign your comments with ~~~~)

Hi. I'm the creator of La Weá and I must say I do not exactly agree with your edits. Sure, most of them may be considered "swear words" (definitely not all), but that doesn't necessarily make them "offensive" here; hence, "colloquial". Although you would need to be acquainted with my language and culture to fully grasp what they convey. As for the "shameful" category, I'm still not really sure how it could fit in there. Anyways, I hope you can understand. --Pelirodri (talk) 2:15, 22 September 2018 (UTC)

Template:License problem

Oerjan, you are a fine, fine, person, and I appreciate your contributions to this wiki, so don't take this personally. But Template:License problem is just silly. If someone posts copyrighted material here, we need to delete it ASAP, not keep it around and put it on display! We can re-add it if the author agrees, of course. I would've thought that was obvious. Maybe you have a good reason for this template, one that hasn't occurred to me -- if so, please say it here. I'll leave the template around for now just in case. --Graue 05:08, 3 Aug 2006 (UTC)

You are probably right, and besides you obviously have final say in this wiki's policy. What made me do this was that the person who entered the material seemed to be the copyright holder, so I thought it was less urgent than usual, and I got the idea of making a warning first. --Ørjan 19:59, 3 Aug 2006 (UTC)

Who's the anal-retentive one?

OK, now seeing as I have made a CPU architecture, someone may just steal it (grrr chinese) and use it in their CPU... "Ooooh, I can't be fucked making an arch, I'll just steal this poor guy's one." Now, compared against public domain...

  • It has one catch: you must include that quote if you wish to redistribute it.

That is my one right. 191 bytes. It's like public domain in these ways (with slight exceptions):

  • You can distribute it, modify it, make deriative works with it (with the condition in this case).
  • You can slap another license on it. (Just keep that license with it.)
  • You can piss on it, stick it in a blender, call it something else. (It just needs that quote)

The one thing you can't do is claim that it's yours. Well you can try, but have a look at the license, and you'll see why it can't be done practically.

I would call it "named public domain." And yet, you didn't do anything with my other langs. What the fuck?! You'd even fuck over an article that had a Creative Commons SA license (FYI: that is "no rights except the fact that it must stay no rights") or a green copyright (the copyright owner has released all rights).

My opinion: One goat.

--GreaseMonkey 01:27, 28 Nov 2006 (UTC)

It has been decided that the contents of this wiki should be public domain. You are certainly within your right to use a different license, but then please put it on a separate web site and link to it instead. --Rune 11:49, 28 Nov 2006 (UTC)

Well, I did give a warning once (see the Template discussion above), and then Graue thought I was silly and should have deleted it outright, so this time I did. Sorry for infuriating you, but this is site policy, and if we didn't have a common license the site might turn into (even more of) a mess. We can't please everybody all the time. And of course I am anal-retentive, I am a nerd you know. :) --Ørjan 02:17, 29 Nov 2006 (UTC)

I did just wanna thank you for your edit of FRAK--Sigfb05 21:20, 25 March 2007 (UTC)

For he's a jolly good fellow

Thanks Oerjan for correcting the typos in the ACRONYM spec, having broken and dislocated my fifth finger (no, really), it would have been excruciatingly painful for me to fix them (no, really) :) -- Hiato 14:53, 25 January 2008 (UTC)

Thank you

Thanks for correcting my typo on Defcalc. Afarnen 21:23, 22 January 2010 (UTC)

User: prefix

Hi, and welcome to Esolang. Unfortunately, the User: before links to user pages is Esolang:Policy, so I have reverted those changes. --Ørjan 15:25, 24 May 2010 (UTC)

Ok, but I feel like it's a weird policy. The articles look like drafts with this prefix. --Piglop 15:33, 1 June 2010 (UTC)

And another thanks!

Thanks for helping me on wikifying the article about tubes! yours Rm minusrf slash

I hate using wikis as a form of interpersonal communication

You may be anal-retentive, but apparently not anal-retentive enough to keep the email address on your home page up to date! What manner of perfidious chicanery is this perfidious chicanery? Please email me your working email address, if you have one. Thank you kindly. Sincerely, the guy who emailed Ørjan only to receive a 554 User Account has Expired response from, November somethingth, 2010

Sorry, I honestly cannot manage to handle this right now. --Ørjan 04:45, 17 November 2010 (UTC)

"copyvio" for User:NSQX/NBF2C.c?

Well, I copied /brainfuck/impl/BF2C.c in the Esoteric File Archive and clearly said that I copied that file, so how is that a copyright violation? Also, the original website that hosted it,, no longer exists so I can't ask the original author for permission. --NSQX 10:14, 7 April 2012 (UTC)

Turns out that copyright violations aren't allowed even if you openly acknowledge they're copyright violations. 11:33, 7 April 2012 (UTC)

(To NSQX.) It is indeed a copyright violation. The original author of the work, Thomas Cort, has let anyone look at and use the work, but there are conditions attached in its license, the GPL. Among these are that any derivative work of the work (such as your NBF2C) are also licensed under the GPL, and that the copyright status is clear.

This wiki doesn't allow information (code, text or otherwise) with copyright status other than public domain. As a result, we don't host GPLed code here. The Esoteric File Archive does allow the hosting of GPLed code, so it would be a more appropriate place.

Also, you've edited out the original copyright notice and license, which is a GPL violation in its own right. The original author has copyright over their contribution to the work even if you make a derivative of it, regardless of whether their website is still online or whether it exists at all. (You have copyright over your changes to it, but as it's based on an original GPLed work, you must license your changes under the GPL yourself to be able to use it.) The resulting program needs a copyright header the same as the one in the original, except that you can change the name of the program, and should have two Copyright (C) lines, one for the original author's copyright, one for your own.

I'm going to blank the page again, because it's violating the wiki's copyright rules. We'll give you some time to copy the file from the page history back to your local computer, in case you don't have a copy yourself. --ais523 17:45, 7 April 2012 (UTC)

Right; the GPL allows people to use the code to create new programs, but you have to retain the full attribution and licensing information from the original program, and you must license your new program itself under the GPL. The easiest way to do this would be to modify the start of the licensing header to look something like this:
 * NBF2C
 * Copyright (C) 2012 NSQX
 * Based on BF2C, copyright (C) 2003 Thomas Cort
(It's okay to remove the additional information in the second comment, just not the licensing header itself.) Once you've made that change, you can get it into the file archive by emailing a copy to Graue, who maintains the archive; his email address is available at As well as allowing copyrighted content, it's also generally more organised and well-suited for storing files than the wiki. Of course, once it's available in the file archive, it's perfectly fine for you to link that file from your wiki user page; we just can't have copyrighted material directly on the wiki. —ehird 17:53, 7 April 2012 (UTC)

Thanks for your help in fixing my formatting problems for Quiney! --(this comment by Nathanator1416j at 16:45, 4 February 2014‎ UTC; please sign your comments with ~~~~)

Turing completeness

I wouldn't mind if you tested one of my (My only) languages, Quiney. I hope I did a good enough job explaining it, if it's hard to understand what I meant, I'd love it if you'd say why in the discussions! Nathanator1416j (talk) 19:17, 11 March 2014 (UTC)

Funny, I always thought it was "Turning"... Nathanator1416j (talk) 12:54, 12 March 2014 (UTC)
No, but we do have Turning tarpits which is something else and probably a pun on people making this mistake. Also, I just realized this wasn't my user talk page, so I'm moving this there. --Ørjan (talk) 13:20, 12 March 2014 (UTC)

Can a programming language be Turing-complete if parts of a computation that determines the Turing-completeness of it from the language is done by hand? (From here, in the text that is indented) --A (talk) 13:10, 8 May 2019 (UTC)

In theory you can do any terminating amount of pre-computation "by hand" (which really means as part of compiling into your language).
But what's important is that you must be able to convert a whole computation (even a non-terminating one) to your language, not just each tiny part of it, and I've got the impression that many of your TC claims have the problem that you only show individual parts but it's very unclear how to put them together in such a way that the whole works.
The arbitrary effect at an arbitrary point idea is a special case of this: that parts can be connected together and the whole does what you expect. When a language has unusual restrictions on how things may be composed this can be the trickiest part of a TC proof.
I suspect what Salpynx is pointing out is an example of the same thing, but I don't really understand Bitch, mostly because the spec is unclear about what exactly happens when chaining instructions, and my brain refuses to read an implementation to find out. --Ørjan (talk) 00:29, 9 May 2019 (UTC)

Deletion Request

Could you please the page User:LegionMammal978/Interpreters/Kangaroo? The idea I had didn't end up working. -- LegionMammal978 (talk) 12:25, 1 January 2016 (UTC)

*POOF* --Ørjan (talk) 00:13, 2 January 2016 (UTC)

All links gone dead

It seems that your esoteric page and all the links to programs and interpreters have gone dead. I hope they will return soon! If I recall correctly I noticed this a few days ago (but it could be less than that). I know it's a very short time but I thought I might just as well tell about it since you might not even have noticed it. --Keymaker (talk) 15:53, 7 December 2017 (UTC)

Some server was down temporarily. I guess I should be happy people notice it... --Ørjan (talk) 20:14, 7 December 2017 (UTC)


There was a programming language called "Lutfig". I saw it in various categories. And it was gone. What on earth is it? --(this comment by BradensEsolangs at 16:56, 19 April 2018‎ UTC; please sign your comments with ~~~~)

The (sole) author of that page requested its deletion after a few months, while it was still in a pretty early draft stage. My impression was that it seemed overambitious, I guess they gave up on fleshing it out. --Ørjan (talk) 01:18, 20 April 2018 (UTC)
When did he? --(this comment by BradensEsolangs at 00:05, 23 April 2018 UTC; please sign your comments with ~~~~)

It was created 25 November 2016 and deleted 20 February 2017. --Ørjan (talk) 08:44, 23 April 2018 (UTC)

--YamTokTpaFa (talk) 01:30, 12 May 2019 (UTC)

I have lots of things I'd like to discuss.

  1. About Esolang talk:Community portal
    • Isn't this working well? Also what do you think of what I posted there?
  2. I'd like to classify each article in this wiki, so any articles about any esoteric languages must be categorized to Category:Languages, I think. What do you think of the policy?
  3. Should I ask anything on Discord next time, instead of this talk page?

--YamTokTpaFa (talk) 13:12, 6 July 2019 (UTC)

...PS. Policy of templates? --YamTokTpaFa (talk) 13:13, 6 July 2019 (UTC)

Problem creating account

A friend of mine is unable to create a new account. The registration claims that the CAPTCHA is missing or incorrect even though we have supplied the correct answer. Could you look into this and come back to me? Thank you in advance. Timwi (talk)

Issue resolved. The problem was that copying the Befunge program in Discord removes the backslashes. Sorry to bother you, though this might be a possible impetus to use a program that doesn’t use backslahes?

Sandbox talk

The Esolang talk:Sandbox page is being treated like a sandbox. Is there anything too be done for this? ColorfulGalaxy (talk) 04:39, 20 November 2021 (UTC)

NOT ANY MORE. Also, anyone can blank a public sandbox. --Ørjan (talk) 04:48, 20 November 2021 (UTC)

Project Euler

Could you please restore this page and blank it? I'm going to put a chart in it. For "restore" I mean using the restore link, not just re-creation. ColorfulGalaxy (talk) 04:39, 20 November 2021 (UTC)

No. It was deleted because all the content was copyright violation. Just recreate it. And don't include anything non-CC0 this time. --Ørjan (talk) 04:48, 20 November 2021 (UTC)


Almost every page created by ColorfulGalaxy on Project Euler started off with an Aheui program. Apparently he can not speak Korean. I suspect that it was copied. Could you please handle it? --(this comment by Guy Fawkes Rep at 15:49, 29 November 2021‎ UTC; please sign your comments with ~~~~)

Not without proof. Or a well-formed request. --Ørjan (talk) 11:41, 5 December 2021 (UTC)
Of course he can't speak Korean , as he's Ch***se. (read his profile) He must have copied it from some emails he received. -- Guy Fawke
Also it's unlikely for him to learn this language within such a short time.
