Did you even try that? 01:37:11 The question is how to inject forgein data safely 01:37:19 ^ 01:37:30 Because, the value x is a primitive so the conversion to an object occurs inside of the sandbox. 01:37:37 the answer is: you really cant. 01:37:38 ^ 01:37:42 ^ 01:37:45 If you replace 42 with {} then it will be the object from outside of the sandbox. 01:37:54 Math.js cant have a sandbox then 01:38:11 And sandboxes will get boring 01:39:09 MathJS dies because of f.constructor for example 01:39:10 You can inject foreign data before executing any untrusted code, if they are primitives rather than objects (functions are also objects). 01:39:22 How is f defined in MathJS anyways? 01:39:41 boily: (In other words, we should have a sesquidecennial celebration late 2017.) 01:39:42 MathJS does some syntax rewriting 01:39:53 It wraps what you provided in another function 01:39:57 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 Syntax rewriting won't help. 01:40:36 It does it just to make it a "more mathematic" syntax 01:40:39 You need to do it properly. 01:40:41 evilvoid: study it a little more, it actually compiles the code into a node based syntax. 01:40:52 and generates JS from that 01:40:52 ^ 01:41:05 It might do syntax rewriting for that reason, but syntax rewriting will not be sufficient to be safe. 01:41:25 for example, (x+1)+6 becomes a syntax tree 01:41:25 you can always eval(String.fromCharCode(stuff)) 01:41:54 Yes, and that is why syntax rewriting is not sufficient. 01:42:28 fizzie: fizziello. that long?!? 01:42:42 not giving ANYTHING makes features useless 01:42:50 (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 like auth0 uses "web containers" (idk in deep how that works) for evaling user code like to rewrite users 01:43:57 boily: http://esoteric.sange.fi/archive/2002-q4 and look up "Esolang IRC channel". 01:44:01 You can give stuff; just make sure you do it properly! Such as by wrapping functions and that kind of stuff 01:44:03 Also you cant put a timeout 01:44:09 Use proxies if necessary. 01:44:12 Since execution is outside ssandbox 01:44:25 * boily is touching history 01:44:59 You could use a separate process and communicate with signals if you want to do timeouts 01:45:08 fizzie: speaking of history, have you updated the fizziegraphs lately? 01:45:24 boily: Not in a long, long time. 01:45:39 I could try to figure out how to do it, and see if the scripts even still work. 01:46:38 updating target 2, days 2015-09-11 ... 2016-09-24 01:46:53 Heh, almost exactly a year has passed. 01:47:16 -!- otherbot has changed nick to evilrbot. 01:47:16 -!- evilator has joined. 01:47:45 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 my god. too. much. evil 01:48:06 [wiki] [[Al Dente]] M https://esolangs.org/w/index.php?diff=49771&oldid=49770 * CatIsFluffy * (+4) fixed bug in EBNF allowing for (a or b).c 01:48:16 boily: I should probably readjust the "channel regulars" whitelist some day, to account for changes. 01:49:10 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 Its almost impossible to give values 01:50:00 SInce you can constructor them to get true Function(tm) 01:50:03 I think someone else has also made up a sandbox out of proxies. 01:50:25 This is the first safe sandbox I see 01:51:02 and all that was needed was a single #esoteric memeber and a one liner 01:51:09 lol 01:51:28 Well, the sandbox/sandcastle guys wasted their time 01:51:57 +1 01:52:03 The way I did it, you can't "constructor them to get true Function(tm)", I think. 01:52:26 (But your tests were doing it wrong; not the way I meant) 01:52:49 -!- Gregor has joined. 01:52:53 What you did is a empty context, which returns a function scoped to the sandbox 01:53:01 Well, scoped is not the correct word 01:53:05 Its like bound to it 01:53:08 Hello I sometimes exist 01:53:15 fizzie: is that the actual gregor?:P bcause the chmod 000/0000 / -R issue needs fixed 01:53:18 -!- Gregor has changed nick to Guest77839. 01:53:48 Yup thats gregor. hi mr person i've never met who wrote HackEgo 01:53:51 I assume it is, though the nickserv-induced nickname change is a little amusing. 01:53:58 -!- Guest77839 has changed nick to Gregor. 01:54:12 holy fungot!

07:35:55 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 Which book? 07:36:17 And I think it does equal d(dy/dx)/dx 07:36:55 Here: 07:37:13 d(dy/dx)/dx = (dx d(dy) - dy d(dx))/(dx^3) 07:37:35 = d(dy)/dx^2 - dy/dx d(dx)/dx^2 07:37:52 And I think d(dx)/dx^2 = 0 07:38:13 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 shocking 07:44:22 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 wait 07:45:29 the last one is in the wrong order 07:45:55 so it's actually infinity hth 07:50:44 -!- digin4 has joined. 07:51:20 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 yes hth 07:51:58 good counterexample oerjan++ tdh 07:52:52 So maybe d(dx)/dx^2 isn't 0? 07:54:19 Really, it couldn't be 0, that would make this whole thing break. 07:54:42 well d^2x/dx^2 is supposedly 0. 07:55:23 If it's the second derivative it would have to be. 07:55:46 Let's see. One way to make this whole thing work is to parameterize everything in terms of t, right? 07:56:05 MAYBE 07:56:13 So dy/dx = D_t(y)/D_t(x) 07:56:48 Where D_t(e) means what people usually mean by de/dt 07:57:35 Certainly D_t(y)/D_t(x) = D_x(y), right? 07:58:35 So the second derivative is D_t(D_t(y)/D_t(x))/D_t(x) 07:58:39 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 Well, it's really just what I wrote earlier except with a more complicated symbol for d. 07:58:50 -!- zzo38 has quit (Disconnected by services). 07:58:52 -!- zzo38_ has changed nick to zzo38. 07:59:06 zzo38: Which book does Penrose pen his objection in? 07:59:49 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 oerjan: that would be scow though 08:00:29 if (dy/dx) (dy/dx) isn't (dy dy)/(dx dx) then this notation is broken 08:00:51 yep 08:01:23 basically because first and second derivatives have no simply scaling correspondence. 08:01:56 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 right? 08:02:38 -!- digin4 has quit (Quit: Leaving). 08:03:36 well sure, everything works nice as long as you're only dealing with first derivatives. 08:03:40 *nicely 08:03:46 *as long as 08:04:03 so you're not objective to (dy/dx)^2 = (dy^2/dx^2) 08:04:08 objecting 08:04:41 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 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 well one of the senses is _defined_ by that connection, of course. 08:06:11 right 08:06:21 -!- ybden has joined. 08:06:22 -!- ybden has quit (Excess Flood). 08:06:56 -!- ybden has joined. 08:06:57 -!- ybden has quit (Excess Flood). 08:07:07 if this notation works, then by definition if y = f(x) then d^2y/dx^2 = f''(x) 08:07:09 right? 08:07:21 duh 08:07:32 so d^2y = f''(x) dx^2 08:07:45 but if f(x) = x, that means d^2y = 0 08:08:03 shachaf: Penrose wrote it in a footnote in Road to Reality (not a part of the main text). 08:08:38 -!- ybden has joined. 08:08:38 -!- ybden has quit (Excess Flood). 08:09:27 that seems problematic 08:09:36 or is it? 08:09:43 -!- ybden has joined. 08:09:43 -!- ybden has quit (Excess Flood). 08:10:24 ybden is sure rejoining a lot 08:10:53 zzo38: Oh, I have a copy of that book, I think.

Not 0? 08:26:25 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 zzo38: That's certainly in contradiction with what the author says about differential forms etc. 08:26:41 *it doesn't have 08:27:24 I know, but apparently a 1-form or whatever is a special case or something like that? 08:27:25 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))? 08:27:42 shachaf: i'm not in a state of mind to even parse that at the moment. 08:27:52 -!- hppavilion[1] has joined. 08:27:57 oerjan: The second derivative at a point is a bilinear map. 08:27:58 Right? 08:28:14 s/U/R/g 08:28:18 i'm also not in a state of mind to understand the concept hth 08:28:38 oerjan: Well, if f : R^n -> R^m, then Df : R^n -> (R^n -o R^m) 08:28:38 Right? 08:28:45 or body. this neck is killing me. 08:29:06 At each point it gives you a linear approximation of f around that point. 08:29:22 shachaf: please consider me just a rubber duck at this point hth 08:29:30 `? oerjan 08:29:31 Your mysterious evil hungarian oerlord immoritus oerjan is a lazy expert in future computation.

(I just got an answer that I was able to prove was equal to Penrose's answer.) 10:31:54 Which answer? 10:32:36 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 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 Maybe I should ask: Answer to what? 10:33:26 oerjan: i know you said that but i didn't understand it so i decided to ignore it hth 10:33:46 thought so. 10:34:06 Now I think I see what you mean, but I'm not sure it's true. 10:34:23 this isn't taking a limit, yo 10:34:43 dy/dx is just an expression in x 10:35:08 dy/dx = 2x or something 10:35:13 maybe, maybe it is true, though 10:35:42 also, my comment about rubber duck means that i'm not reading half of what you write hth 10:35:53 half of what i write is wrong 10:35:58 i hope that's the half you're not reading twh 10:36:50 Say x^2+y^2=1 10:37:01 2x dx + 2y dy = 0 10:37:25 y dy = -x dx 10:37:53 incidentally, that's equivalent to saying "a circle is always normal to its radius" 10:38:09 yes 10:38:33 it's much nicer than dy/dx = -x/sqrt(1-x^2) or whatever you might write 10:39:13 OK, let's parameterize it. 10:39:26 x = cos t, y = sin t 10:40:05 dx = -sin t dt, dy = cos t dt 10:40:06 -!- hppavilion[1] has quit (Ping timeout: 264 seconds). 10:40:24 er 10:40:29 scrap that 10:40:32 x = cos t, y = sin t 10:40:41 dx = -sin t, dy = cos t 10:40:59 what am i even doing 10:41:24 dx = -y, dy = x 10:41:25 incidentally, the half i'm not reading includes most of the formulas hth 10:41:41 dy/dx = -x/y 10:42:03 d(dy) = -y 10:42:49 d(dx) = -x 10:43:44 d(dy)/dx^2 = -y/(y^2) = -1/y 10:44:03 is that right 10:45:27 quack but i dislike confusing functions and expressions. 10:46:28 these are expressions 10:46:45 the d(dy) = -y part is just sin'' = -sin and cos'' = -cos 10:46:57 yes 10:47:03 since x and y are expressions in t 10:47:10 what's confused there 10:48:05 the d operator applied to an expression. 10:48:36 yes, d means "derivative with respect to t" 10:48:42 as specified a few pages ago 10:48:49 quack. 10:49:17 look, is -1/y the right second derivative? 10:49:30 oh, i guess i could differentiate and see 10:50:11 for a half circle the usual way it would be the derivative of -x/sqrt(1-x^2) 10:51:29 = (y d(-x)/dx - (-x) dy/dx)/y^2 10:52:07 = (x dy/dx - y)/y^2 10:52:14 dy/dx = -x/y 10:52:45 so that's (-x^2/y - y)/y^2 10:53:08 = -x^2/y^3 - 1/y 10:53:10 hm 10:54:05 the second derivative of sqrt(1-x^2) is -1/(sqrt(1-x^2)^3) 10:54:25 quack 10:54:27 so -1/(y^3) 10:54:35 which is neither of the other two answers i got 10:54:49 probably because i haven't done this in years and also it's 3 in the morning 10:55:23 ok, well, the hand derivative i just did wrong 10:55:48 but -1/y isn't right, it's -1/y^3 10:55:55 let me try one more time 10:56:02 x = cos t, y = sin t 10:56:16 dx = -y, dy = x 10:56:24 d(dx) = -x, d(dy) = -y 10:57:03 d(dy)/(dx^2) = -y/(y^2) = -1/y 10:57:37 `? evilipse 10:57:38 ​ the most obnoxious of evil people, likes to use chmod 000 / -R 10:57:57 `slwd evilipse//s//evilipse,/ 10:57:59 sed: -e expression #1, char 0: no previous regular expression 10:58:08 `slwd evilipse//s/^/evilipse,/ 10:58:10 wisdom/evilipse//evilipse, the most obnoxious of evil people, likes to use chmod 000 / -R 10:58:57 ok, dy/dx = -x/y 10:59:52 d(-x/y) = (y d(-x) - (-x) dy)/y^2 11:00:32 = (y^2 + x^2)/y^2 11:00:45 = 1/y^2 11:00:54 so d(-x/y)/dx = 1/y^3 11:01:09 so at least that's right 11:01:26 but why does that not work in the other problem, and d^2y/dx^2 not work in this problem? 11:01:29 please advise 11:01:39 quack. 11:01:42 so tired 11:02:09 maybe the whole premise is broken? 11:02:09 I thought of variant of Archenemy game of Magic: the Gathering where the players must bid on being the solo player.
