00:22:38 -!- hppavilion[1] has joined.
00:23:40 <zzo38> If the code inside of the sandbox is not a arrow function but is a proper function then it may also leak "this"; you can specify the this value yourself (such as undefined) if called by Reflect.apply instead.
00:23:42 <evilvoid> what I sent last?
00:24:27 <evilvoid> The issue is that when you want to inject some helper functions
00:24:41 <evilvoid> Like your own math things
00:25:56 <zzo38> Yes, I know. That is why I suggested things such as: sandbox.func1=vm.runInContext("(x=>y=>{ "use strict"; if(typeof y!=="number") throw new TypeError(); else return x(y);)")(my_math_function) for example (before executing any untrusted code in the sandbox)
00:26:23 <zzo38> Actually that is not quite right. Here it is: sandbox.func1=vm.runInContext("(x=>y=>{ "use strict"; if(typeof y!=="number") throw new TypeError(); else return x(y);)",sandbox)(func1);
00:26:27 <evilmoon> sounds like what math.js did

01:36:45 <fizzie> boily: Late 2002.
01:36:46 <evilvoid> And because 42 is a primitive...
01:36:49 <zzo38> Yes, there you have leaked the "this" because you are not doing what it is supposed to do
01:36:59 <evilvoid> ^
01:37:07 <zzo38> It demonstrates that the result of vm.runInContext("(x=>x.constructor.constructor)",vm.createContext(Object.create(null)))(42) is not the same Function object; if you write ==Function then it will be false. Did you even try that?
01:37:11 <evilvoid> The question is how to inject forgein data safely
01:37:19 <evilmoon> ^
01:37:30 <zzo38> Because, the value x is a primitive so the conversion to an object occurs inside of the sandbox.
01:37:37 <evilmoon> the answer is: you really cant.
01:37:38 <evilvoid> ^
01:37:42 <evilvoid> ^
01:37:45 <zzo38> If you replace 42 with {} then it will be the object from outside of the sandbox.
01:37:54 <evilvoid> Math.js cant have a sandbox then
01:38:11 <evilvoid> And sandboxes will get boring
01:39:09 <evilvoid> MathJS dies because of f.constructor for example
01:39:10 <zzo38> You can inject foreign data before executing any untrusted code, if they are primitives rather than objects (functions are also objects).
01:39:22 <zzo38> How is f defined in MathJS anyways?
01:39:41 <fizzie> boily: (In other words, we should have a sesquidecennial celebration late 2017.)
01:39:42 <evilvoid> MathJS does some syntax rewriting
01:39:53 <evilvoid> It wraps what you provided in another function
01:39:57 <zzo38> Also, ensure that the sandbox object is created without a prototype! (This is what Object.create(null) means; it means to create an object with no prototype)
01:40:14 <zzo38> Syntax rewriting won't help.
01:40:36 <evilvoid> It does it just to make it a "more mathematic" syntax
01:40:39 <zzo38> You need to do it properly.
01:40:41 <evilmoon> evilvoid: study it a little more, it actually compiles the code into a node based syntax.
01:40:52 <evilmoon> and generates JS from that
01:40:52 <evilvoid> ^
01:41:05 <zzo38> It might do syntax rewriting for that reason, but syntax rewriting will not be sufficient to be safe.
01:41:25 <evilmoon> for example, (x+1)+6 becomes a syntax tree
01:41:25 <evilvoid> you can always eval(String.fromCharCode(stuff))
01:41:54 <zzo38> Yes, and that is why syntax rewriting is not sufficient.
01:42:28 <boily> fizzie: fizziello. that long?!?
01:42:42 <evilvoid> not giving ANYTHING makes features useless
01:42:50 <zzo38> (I also made a TeX sandbox that does not attempt to validate the input or anything like that; security is done by using a custom format file instead. This requires One True TeX and will not work with pdfTeX or LaTeX or other variants.)
01:43:24 <evilvoid> like auth0 uses "web containers" (idk in deep how that works) for evaling user code like to rewrite users
01:43:57 <fizzie> boily: http://esoteric.sange.fi/archive/2002-q4 and look up "Esolang IRC channel".
01:44:01 <zzo38> You can give stuff; just make sure you do it properly! Such as by wrapping functions and that kind of stuff
01:44:03 <evilvoid> Also you cant put a timeout
01:44:09 <zzo38> Use proxies if necessary.
01:44:12 <evilvoid> Since execution is outside ssandbox
01:44:25 * boily is touching history
01:44:59 <zzo38> You could use a separate process and communicate with signals if you want to do timeouts
01:45:08 <boily> fizzie: speaking of history, have you updated the fizziegraphs lately?
01:45:24 <fizzie> boily: Not in a long, long time.
01:45:39 <fizzie> I could try to figure out how to do it, and see if the scripts even still work.

01:47:16 -!- evilator has joined.
01:47:45 <zzo38> If you write vm.createContext({}) then it is unsafe because it can take values from the outside's Object.prototype, but with Object.create(null) it has no prototype, so that part is undone at least.
01:47:46 <evilmoon> my god. too. much. evil

01:48:16 <fizzie> boily: I should probably readjust the "channel regulars" whitelist some day, to account for changes.
01:49:10 <zzo38> If f is a function brought into the sandbox like how I suggested (wrapping it inside of a function created in the sandbox, by creating a function that returns a function also inside of the sandbox), then it will be the function inside of the sandbox and not outside. Stuff outside of the definition of that function cannot access its local variables.
01:49:34 <evilvoid> Its almost impossible to give values
01:50:00 <evilvoid> SInce you can constructor them to get true Function(tm)
01:50:03 <zzo38> I think someone else has also made up a sandbox out of proxies.
01:50:25 <evilvoid> This is the first safe sandbox I see
01:51:02 <evilmoon> and all that was needed was a single #esoteric memeber and a one liner
01:51:09 <evilvoid> lol
01:51:28 <evilvoid> Well, the sandbox/sandcastle guys wasted their time
01:51:57 <evilmoon> +1
01:52:03 <zzo38> The way I did it, you can't "constructor them to get true Function(tm)", I think.
01:52:26 <zzo38> (But your tests were doing it wrong; not the way I meant)
01:52:49 -!- Gregor has joined.
01:52:53 <evilvoid> What you did is a empty context, which returns a function scoped to the sandbox
01:53:01 <evilvoid> Well, scoped is not the correct word

07:31:42 <shachaf> zzo38: But d(dx)/dx^2 = 0, right?
07:31:51 <izalove> almost the same code works fine with vector https://arin.ga/NZCIsJ/raw
07:32:27 <zzo38> shachaf: I don't know; I haven't tried to figure out
07:33:24 <zzo38> But, second derivative can be d(dy/dx)/dx even though the notation d^2y/dx^2 is used but that notation is wrong.
07:33:38 <shachaf> I don't think that notation is wrong.
07:33:54 <shachaf> I used to think it was odd and arbitrary but now I'm thinking it's actually good.
07:34:14 <shachaf> Why do you say it's wrong?
07:35:55 <zzo38> Because d^2y/dx^2 doesn't equal d(dy/dx)/dx, and also I saw in another book (by Penrose) that it is wrong!
07:36:09 <shachaf> Which book?
07:36:17 <shachaf> And I think it does equal d(dy/dx)/dx
07:36:55 <shachaf> Here:
07:37:13 <shachaf> d(dy/dx)/dx = (dx d(dy) - dy d(dx))/(dx^3)
07:37:35 <shachaf> = d(dy)/dx^2 - dy/dx d(dx)/dx^2
07:37:52 <shachaf> And I think d(dx)/dx^2 = 0
07:38:13 <shachaf> I can say that it's because the second derivative of x with respect to x is 0, but that's circular. :-)
07:39:15 <oerjan> shocking
07:44:22 <oerjan> but then (dy/dx)^2 = dy^2/dx^2 = (d^2y/dy^2) / (d^2y/dx^2) = 0 whenever d^2y/dx^2 /= 0 checkmate atheists
07:45:16 <oerjan> wait
07:45:29 <oerjan> the last one is in the wrong order
07:45:55 <oerjan> so it's actually infinity hth
07:50:44 -!- digin4 has joined.
07:51:20 <shachaf> are you saying (dy/dx)^2 = (dy^2/dx^2) = (1/dx^2)/(1/dy^2) = (d^2y/dx^2)/(d^2y/dy^2) = (d^2y/dx^2)/0
07:51:50 <oerjan> yes hth
07:51:58 <shachaf> good counterexample oerjan++ tdh
07:52:52 <shachaf> So maybe d(dx)/dx^2 isn't 0?
07:54:19 <shachaf> Really, it couldn't be 0, that would make this whole thing break.
07:54:42 <oerjan> well d^2x/dx^2 is supposedly 0.
07:55:23 <shachaf> If it's the second derivative it would have to be.
07:55:46 <shachaf> Let's see. One way to make this whole thing work is to parameterize everything in terms of t, right?
07:56:05 <oerjan> MAYBE
07:56:13 <shachaf> So dy/dx = D_t(y)/D_t(x)
07:56:48 <shachaf> Where D_t(e) means what people usually mean by de/dt
07:57:35 <shachaf> Certainly D_t(y)/D_t(x) = D_x(y), right?
07:58:35 <shachaf> So the second derivative is D_t(D_t(y)/D_t(x))/D_t(x)
07:58:39 <oerjan> i think the trouble may be simply that second derivatives in this notation don't behave sensibly wrt changes of variables.
07:58:47 -!- zzo38_ has joined.
07:58:49 <shachaf> Well, it's really just what I wrote earlier except with a more complicated symbol for d.

07:58:52 -!- zzo38_ has changed nick to zzo38.
07:59:06 <shachaf> zzo38: Which book does Penrose pen his objection in?
07:59:49 <oerjan> or put differently, dy^2/dx^2, the thing you need to change variables for second derivatives, is not (dy/dx)^2 where dy/dx is the thing you need for first derivatives.
07:59:50 <shachaf> oerjan: that would be scow though
08:00:29 <shachaf> if (dy/dx) (dy/dx) isn't (dy dy)/(dx dx) then this notation is broken
08:00:51 <oerjan> yep
08:01:23 <oerjan> basically because first and second derivatives have no simply scaling correspondence.
08:01:56 <shachaf> but parameterize it in terms of t. certainly (dy/dt)/(dx/dt) * (dy/dt)/(dx/dt) = ((dy/dt)(dy/dt))/((dx/dt)(dx/dt))
08:01:59 <shachaf> right?
08:02:38 -!- digin4 has quit (Quit: Leaving).
08:03:36 <oerjan> well sure, everything works nice as long as you're only dealing with first derivatives.
08:03:40 <oerjan> *nicely
08:03:46 <oerjan> *as long as
08:04:03 <shachaf> so you're not objective to (dy/dx)^2 = (dy^2/dx^2)
08:04:08 <shachaf> objecting
08:04:41 <oerjan> i'm objecting that there are two different senses of dy^2/dx^2 which don't scale in the same way.
08:05:29 <shachaf> well, the real problem here isn't with squaring dy or any of that, it's with the connection to d^2y
08:05:52 -!- ybden has joined.
08:05:52 -!- ybden has quit (Excess Flood).
08:06:02 <oerjan> well one of the senses is _defined_ by that connection, of course.

08:06:57 -!- ybden has quit (Excess Flood).
08:07:07 <shachaf> if this notation works, then by definition if y = f(x) then d^2y/dx^2 = f''(x)
08:07:09 <shachaf> right?
08:07:21 <oerjan> duh
08:07:32 <shachaf> so d^2y = f''(x) dx^2
08:07:45 <shachaf> but if f(x) = x, that means d^2y = 0
08:08:03 <zzo38> shachaf: Penrose wrote it in a footnote in Road to Reality (not a part of the main text).

08:09:27 <shachaf> that seems problematic

08:09:43 -!- ybden has quit (Excess Flood).
08:10:24 <shachaf> ybden is sure rejoining a lot
08:10:53 <shachaf> zzo38: Oh, I have a copy of that book, I think. Do you remember which footnote?
08:12:28 <zzo38> No I do not remember
08:13:23 <shachaf> Actually it doesn't seem problematic.
08:13:40 <shachaf> If dy = 0, that means dy is constant.
08:13:46 <shachaf> Er, y is constant.
08:14:01 <shachaf> So if d(dy) = 0, that means dy is constant.
08:14:26 <zzo38> Yes.
08:14:37 <zzo38> I know that.
08:14:49 <zzo38> (They even say so in the book.)
08:14:59 <shachaf> I know, I'm looking at the book.
08:19:14 <shachaf> zzo38: So what's d(dy/dx)?
08:19:58 -!- mtve has joined.
08:20:05 <shachaf> I guess it's what I said above: (dx d(dy) - dy d(dx))/dx^2
08:21:01 <shachaf> = d(dy)/dx - dy/dx d(dx)/dx
08:23:24 -!- Robdgreat_ has changed nick to Robdgreat.
08:24:26 <shachaf> So d(dy/dx)/dx = d(dy)/dx^2 - dy/dx d(dx)/dx^2
08:24:37 <shachaf> So what's that second part? Not 0?
08:26:25 <oerjan> put in a different way, in d^2 / dx^2 the two dx'es come from different scopes, and if there's a dy/dx have to be the same in the two scopes.
08:26:25 <shachaf> zzo38: That's certainly in contradiction with what the author says about differential forms etc.
08:26:41 <oerjan> *it doesn't have
08:27:24 <zzo38> I know, but apparently a 1-form or whatever is a special case or something like that?
08:27:25 <shachaf> oerjan: This is probably related to how if you have f : U^n -> U^m, D^2f : U^n -> (U^n -o (U^n -o U^m))?

09:30:49 <zzo38> Also it can be use even if different compilers have different name mangling schemes.
09:31:20 <oerjan> oh someone managed to break it?

09:32:41 <oerjan> wat
09:33:05 <fizzie> oerjan: Yes, turns out if you set the permissions of /hackenv (which is read-write in the sandbox) to 0, it goes (well, used to go) to a mode where nothing works because the hg commands can't access the .hg subdirectory, requiring manual intervention.
09:33:58 <oerjan> fizzie: doesn't `revert still work?
09:34:07 <zzo38> shachaf: If it is converted into a C header file instead of C++ then it won't matter after it has been converted, because it uses the name-mangling scheme of the converter.
09:35:01 <fizzie> oerjan: No -- it does "work" in the sense that it attempts to execute the commands (since that happens outside the sandbox), but the 'hg revert' it uses just fails.
09:35:34 <oerjan> fizzie: i somehow didn't think the internal HackEgo commands accessed .hg through /hackenv ...
09:35:57 <oerjan> iirc .hg wasn't even always inside it...
09:36:07 <oerjan> maybe i remember wrong.
09:36:16 <fizzie> It's always been a subdirectory the times I've been playing with it.
09:37:12 <fizzie> And yeah, from the internal command's perspective it's not /hackenv, it's /home/hackbot/hackbot.hg/multibot_cmds/env, but a chmod on /hackenv in the sandbox translates directly to a chmod on that, since it's mounted read-write.

10:15:59 <oerjan> shachaf: i thought that was what i did, except i couldn't remember the english spelling.
10:16:18 <shachaf> Ah, I thought it was meant to be "wuss out"
10:16:43 <shachaf> Where "weasel out" would be more appropriate, because woozles are related to weasels.
10:18:27 <shachaf> OK, let's take a case like x=t^2, y=t^3
10:18:47 <shachaf> I said that d(dy)/dx^2 = dy/dx d(dx)/dx^2 + d(dy/dx)/dx
10:19:05 <shachaf> So d(dy/dx)/dx = d(dy)/dx^2 -dy/dx d(dx)/dx^2
10:19:12 <shachaf> d(dy/dx)/dx = d(dy)/dx^2 - dy/dx d(dx)/dx^2
10:20:17 <shachaf> dy = 3t^2, dx = 2t
10:20:31 <shachaf> dy/dx = 3/2 t
10:21:29 <shachaf> So d(dy/dx)/dx = d(3/2 t)/(2t) = (3/2)/(2t) = 3/(4t)
10:21:58 <shachaf> d(dy) = 6t, d(dx) = 2
10:22:10 <shachaf> dx^2 = 4t^2
10:23:00 <shachaf> So we have 6t/(4t^2) - 3/2 t 2/(4t^2)
10:23:26 <oerjan> quack.
10:23:48 <shachaf> = (6t - 3t)/4t^2
10:24:16 <shachaf> = 3/4 t
10:24:28 <shachaf> So that extra dy/dx d(dx)/dx^2 adjustment did exactly the wrong thing.
10:24:37 <shachaf> We wanted 3/2 t
10:25:37 <shachaf> But note that d(dy)/dx^2 = 6t/(4t^2) = 3/2t *is* the right derivative.
10:26:06 <oerjan> shoquack.
10:26:28 <shachaf> oerjan: zzo38 said it was nonsense earlier!
10:26:39 <shachaf> But here we go, d^y/dx^2 actually does work.
10:26:51 <shachaf> It's just that my claim about the d^2x/dx^2 was wrong
10:26:58 <shachaf> Why is that?
10:27:06 <oerjan> skeptiquack about d^y/dx^2 hth
10:27:20 <shachaf> Does it not work in this case?
10:27:57 <shachaf> Er, d^2y/dx^2
10:28:15 <shachaf> skeptiquacks are exactly what i need tdh
10:29:46 <shachaf> So what am I doing wrong?
10:31:44 <zzo38> If d^2y/dx^2 is OK then maybe did I miss some simplification steps in my calculation? (I just got an answer that I was able to prove was equal to Penrose's answer.)
10:31:54 <shachaf> Which answer?
10:32:36 <zzo38> I forget now, but I remembered when I simplified both answers I got the same thing in each case, showing them to be equal.
10:32:46 <oerjan> when calculating second derivatives, you have to let the dx's from calculating the first derivatives go to 0 _first_, because there's no continuity property that allows you to defer it. this means that you _cannot_ treat dx^2 as having the same dx variable twice... they come from different scopes, as i said.
10:32:49 <shachaf> Maybe I should ask: Answer to what?
10:33:26 <shachaf> oerjan: i know you said that but i didn't understand it so i decided to ignore it hth
10:33:46 <oerjan> thought so.
10:34:06 <shachaf> Now I think I see what you mean, but I'm not sure it's true.
10:34:23 <shachaf> this isn't taking a limit, yo
10:34:43 <shachaf> dy/dx is just an expression in x
10:35:08 <shachaf> dy/dx = 2x or something
10:35:13 <shachaf> maybe, maybe it is true, though
10:35:42 <oerjan> also, my comment about rubber duck means that i'm not reading half of what you write hth
10:35:53 <shachaf> half of what i write is wrong
10:35:58 <shachaf> i hope that's the half you're not reading twh
10:36:50 <shachaf> Say x^2+y^2=1
10:37:01 <shachaf> 2x dx + 2y dy = 0
10:37:25 <shachaf> y dy = -x dx
10:37:53 <oerjan> incidentally, that's equivalent to saying "a circle is always normal to its radius"
10:38:09 <shachaf> yes
10:38:33 <shachaf> it's much nicer than dy/dx = -x/sqrt(1-x^2) or whatever you might write
10:39:13 <shachaf> OK, let's parameterize it.
10:39:26 <shachaf> x = cos t, y = sin t
10:40:05 <shachaf> dx = -sin t dt, dy = cos t dt

10:40:41 <shachaf> dx = -sin t, dy = cos t
10:40:59 <shachaf> what am i even doing
10:41:24 <shachaf> dx = -y, dy = x
10:41:25 <oerjan> incidentally, the half i'm not reading includes most of the formulas hth
10:41:41 <shachaf> dy/dx = -x/y
10:42:03 <shachaf> d(dy) = -y
10:42:49 <shachaf> d(dx) = -x
10:43:44 <shachaf> d(dy)/dx^2 = -y/(y^2) = -1/y
10:44:03 <shachaf> is that right
10:45:27 <oerjan> quack but i dislike confusing functions and expressions.
10:46:28 <shachaf> these are expressions
10:46:45 <oerjan> the d(dy) = -y part is just sin'' = -sin and cos'' = -cos
10:46:57 <shachaf> yes
10:47:03 <shachaf> since x and y are expressions in t
10:47:10 <shachaf> what's confused there
10:48:05 <oerjan> the d operator applied to an expression.
10:48:36 <shachaf> yes, d means "derivative with respect to t"
10:48:42 <shachaf> as specified a few pages ago
10:48:49 <oerjan> quack.
10:49:17 <shachaf> look, is -1/y the right second derivative?
10:49:30 <shachaf> oh, i guess i could differentiate and see
10:50:11 <shachaf> for a half circle the usual way it would be the derivative of -x/sqrt(1-x^2)
10:51:29 <shachaf> = (y d(-x)/dx - (-x) dy/dx)/y^2
10:52:07 <shachaf> = (x dy/dx - y)/y^2
10:52:14 <shachaf> dy/dx = -x/y
10:52:45 <shachaf> so that's (-x^2/y - y)/y^2
10:53:08 <shachaf> = -x^2/y^3 - 1/y
10:53:10 <shachaf> hm
10:54:05 <shachaf> the second derivative of sqrt(1-x^2) is -1/(sqrt(1-x^2)^3)
10:54:25 <oerjan> quack
10:54:27 <shachaf> so -1/(y^3)
10:54:35 <shachaf> which is neither of the other two answers i got
10:54:49 <shachaf> probably because i haven't done this in years and also it's 3 in the morning
10:55:23 <shachaf> ok, well, the hand derivative i just did wrong
10:55:48 <shachaf> but -1/y isn't right, it's -1/y^3
10:55:55 <shachaf> let me try one more time
10:56:02 <shachaf> x = cos t, y = sin t
10:56:16 <shachaf> dx = -y, dy = x
10:56:24 <shachaf> d(dx) = -x, d(dy) = -y
10:57:03 <shachaf> d(dy)/(dx^2) = -y/(y^2) = -1/y

11:02:25 <shachaf> how do they bid?
11:02:30 <shachaf> or what
11:06:23 <zzo38> I thought you can bid how many points you will earn, which will also control cards you must ante at first and how many times that when you would set a scheme in motion instead you must look at the top card of your scheme deck and decide to either leave it there or move it to the bottom.

21:17:24 <wob_jonas> It turns out, that on the older versions of the euro notes, printed before 2013..2015, the euro symbol is much less prominent, in particular it doesn't appear as a large white symbol printed on the top left corner on the back side.
21:17:42 <wob_jonas> That is definitely part of why I assumed the euro symbol didn't appear on the euro banknotes.

21:40:04 <\oren\> the RMB has apparently got on it Chinese, mandarin pinyin, Mongolian, Tibetan, Uyghur (in Arabic script), and Zhuang.
21:40:05 <wob_jonas> fizzie: EKB is also only on the newer versions of the notes
21:40:25 <fizzie> Well, you joined later.
21:41:04 <wob_jonas> the old version has what looks like "BCE ECB EZB EKT EKP", where presumably ECB and BCE are English and French, who always reverse their acronyms
21:41:35 <fizzie> EKP is there just for Finnish and Estonian.
21:42:03 <wob_jonas> the newer one has "BCE ECB E<russian ts><russian b> EZB EKP EKT EKB B<c with dot above>E EBC"
21:43:09 <wob_jonas> I would guess EZB is german, and the one with c with dot above is probably slovakian.
21:43:35 <\oren\> Zentral? weird
21:43:46 <wob_jonas> that's just a guess
21:43:49 <wob_jonas> I don't really know
21:44:37 <\oren\> wikipedia says Europa:ische Zentralbank
21:45:18 <\oren\> because the germans like to squeeze words together even if they would happily stand on their own
21:45:42 <wob_jonas> \oren\: yes, and zentral is definitely a real german word
21:45:49 <wob_jonas> so that sounds pretty plausible

22:29:55 <moonythedwarf> oerjan: i have a reversable 2d language with 3 instructions: / (mirror 1) \ (mirror 2) and < (split/join), how could i combine \ and / ?
22:30:36 <oerjan> why would you do that, it's nicely symmetric. also have you looked at BackFlip
22:31:21 * oerjan doesn't think anyone ever found a good way of programming it.
22:32:08 <oerjan> you seem to have chosen similar command characters, at least.
22:32:33 <moonythedwarf> yay i have less instructions :P i came up with it during school, just chose some symbols that look like my diagrams
22:32:36 <oerjan> but split/join doesn't sound like what < does in backflip.
22:32:38 <wob_jonas> oerjan: nice. wasn't there also some 2d fungeoid language with only two different characters, space and a tricky one?
22:32:53 <oerjan> wob_jonas: Jolverine?
22:33:01 <wob_jonas> no, it's Black
22:33:03 <oerjan> there may be more than one.
22:33:27 <oerjan> (Jolverine is also reversible)
22:33:37 <moonythedwarf> oerjan: what i looked at for insperation was the billard ball machine (https://esolangs.org/wiki/Billiard_ball_machine) page
22:34:27 -!- hppavilion[1] has joined.
22:34:51 <oerjan> moonythedwarf: funny way of getting inspired, the /\< chars there seem to be just for demonstration...
22:34:52 <moonythedwarf> i never saw the backflip page
22:35:05 <moonythedwarf> i know, i wanted to try something similar
22:35:20 <moonythedwarf> now that a look at it again, i could possibly only use two instructions and diagonal only moving balls
22:35:21 <oerjan> as in, not actually part of the language
22:35:27 <wob_jonas> note that Black is self-modifying (modifies the contents of its instruction cells during execution) in an essential way
22:35:46 <oerjan> was Black reversible too...
22:36:31 <moonythedwarf> wob_jonas: the topic right now is reversable languages
22:36:43 <wob_jonas> ah
22:38:24 <oerjan> i'm not sure it was the topic, i only remembered jolverine was reversible after mentioning it.
22:38:26 <wob_jonas> wait, which is that 2d fungeoid that has space and the four arrows as the only commands, and tiling a quarter plane with instructions?
22:39:08 <oerjan> i don't remember
22:40:02 <wob_jonas> it's Nopfunge
22:41:22 <oerjan> wob_jonas: also, Wierd may fit your question too
22:41:33 <oerjan> um, not the last one
22:41:37 <oerjan> but above
22:41:57 <moonythedwarf> oerjan: say i wanted to make a one directional gate in my theoretical language
22:42:07 <moonythedwarf> /\
22:42:10 <moonythedwarf> <<
22:42:13 <moonythedwarf> \/
22:42:38 <moonythedwarf> that would, if the 'ball' came from the left, send it back again
22:42:41 <oerjan> hm, Nopfunge may have been added after i gave up following the wiki.
22:42:48 <moonythedwarf> in fact, actually, cut that last < in the middle line
22:44:12 <oerjan> moonythedwarf: note that if your language is reversible and commands don't change state, then you can only have one input path going to each output path
22:44:15 <wob_jonas> It would be easy to define a 2d language that's equivalent to Nopfunge and uses only two characters (instead of five), but what the machine does depends not only on the character under the pointer, but also on the some characters on adjacent cells.
22:44:28 <oerjan> and vice versa.
22:44:37 <shachaf> `? oerjan
22:44:45 <wob_jonas> Hmm, in fact you could make it even without that.

22:44:57 <oerjan> did HackEgo turn slow again
22:45:02 <wob_jonas> Let me think.
22:45:15 <wob_jonas> No wait, that wouldn't work.
22:46:08 * moonythedwarf is thinking about how to make a turing complete single instruction esolang
22:46:51 <wob_jonas> It would be easy if the pointer always had a speed of two, and the command rotated it right then displaced it by one tile forward in the new direction, so essentially you have the plane colored to four different colors, each color of square used exactly in one of the four compass directions.
