There is even invisible, which I think is good, since sometimes you might want invisible captions, such as if the text is already part of the picture (e.g. the clues in Jeopardy!). However, tag 12 and 13 and 14 is undefined, according to Wikipedia. 00:19:02 I can make the suggestion of the use of these tags: video translation, described video (invisible by default, like tag 15), and miscellaneous (in case none of the other tags are suitable). 00:23:50 -!- oerjan has quit (Quit: Nite). 00:30:02 -!- imode has quit (Ping timeout: 240 seconds). 00:35:19 [[Brainfuck constants]] M https://esolangs.org/w/index.php?diff=66802&oldid=58043 * A * (+38) /* 97 */ 01:11:31 Whoa, more Homestuck 01:11:52 * pikhq should read herself the epilogue 01:40:33 I saw the note by wib_jonas about "vanishing three card blind" M:tG game.

I defined cross-ratio in normal human-readable terms involving exterior product only 10:56:12 though it looks like black magic; I don’t know how to derive it in a straightforward manner, it was constrained guessing 10:58:45 the final result is this: where “metric-dependent” (though independent) definition goes (A, B; C, D) = |AC| |BD| / |BC| |AD|, the invariant one goes (a ∧ c) (b ∧ d) / (b ∧ c) (a ∧ d), and I’m not joking it’s really that similar. As I said, black magic 11:00:28 where a, b, c, d are nonzero vectors from lines A, B, C, D 11:04:50 I specifically was looking for an expression invariant under scaling these a, b, c, d separately, and one that is invariant under any linear maps. This would mean it’s invariant in projective space, and this also enforced fractions and the form where each vector occurs equally often in denominators and numerators. So the simplest expression to satisfy that is the one I got here, upto a permutation of (a, b, c, d) 11:08:25 oh, by (a ∧ c) (b ∧ d) / (b ∧ c) (a ∧ d) I meant (a ∧ c / b ∧ c) (b ∧ d / a ∧ d) (or another rewriting), division is allowed because bivectors are all from one-dimensional space here, as all vectors line in the same plane (as all projective points need to be collinear for cross-ratio to be defined) 11:26:58 eh, I wrote about this in three places and still no reaction :D though I have no patience. I hadn’t seen the expression anywhere to date, so I’m agitated at least because that shouldn’t be the case, it’s simple and it’s definitely useful when teaching. Or learning, for that matter 11:30:22 though contemporarily it’s not a consensus yet that exterior products make many things more transparent. Exterior algebra captures linear dependence, in a way 11:30:41 arseniiv: may I recommend you the book https://esolangs.org/logs/2019-08.html#lN5c ? 11:31:04 b_jonas: I’ll take a look! 11:55:54 -!- atslash has joined. 12:08:47 oh there is a nice remark also that cross-ratio values naturally lie in RP! I should fix my definition so that be the case 12:10:34 and also that the distances in the classical definition are directed. Yes, this makes more sense, and yes it’s nice that the invariant definition was taking that into account all along 12:15:12 (I look at the first edition) 12:27:10 hm constructing a definition such that cross-ratio lies in RP isn’t trivial! 12:27:40 we should divide bivectors or we get nonsense, but we should also take away all divisions 12:28:04 I think there is an invariant way though 12:37:30 -!- xkapastel has joined. 13:07:08 -!- LKoen has quit (Remote host closed the connection). 13:20:31 -!- LKoen has joined. 13:20:35 [[Dilemma]] N https://esolangs.org/w/index.php?oldid=66803 * A * (+635) Created page with "== Drafts == Maze language based on a searching algorithm that does not remember the way it goes.

And of course there's a truckload of different cross-platform development things that just draw their own stuff (Flutter, React Native, Xamarin, that Feathers thing...). 20:47:32 fizzie: I mean for the native android services 20:48:15 Can you run a X server on Android? 20:53:38 I don't see why you couldn't in theory, but I haven't really heard of anyone doing it. 20:54:02 i think people do 20:54:13 because they want to use GUI programs in a GNU/Linux chroot 20:54:20 you can use Xvnc or something 20:55:02 I use Termux on my phone, which is basically an Android terminal emulator app, plus a Linux userland installed inside the app's data directory, and an APT repository for convenient packages. 20:55:10 oxample: https://www.reddit.com/r/amateurradio/comments/84jbgy/wsjtx_on_android/ 20:55:13 fizzie: that sounds dope 20:55:17 I should use that 20:55:21 is it less buggy than juicessh 20:55:25 can you run the linux mosh client in it 20:56:06 So far I like it better than JuiceSSH, which is where I switched from. At least you can run the standard OpenSSH client and ssh-agent. 20:56:15 good 20:56:16 I assume mosh should be fine as well, I've just never set that up. 20:56:19 you can probably run mosh too 20:56:26 it doesn't have much in the way of system requirements 20:56:47 (The nice bit with Termux is that it requires no root.) 20:58:07 Looks like there's also some support for running X11, through the VNC trick: https://wiki.termux.com/wiki/Graphical_Environment 21:06:24 -!- LKoen has joined. 21:07:00 -!- kspalaiologos has quit (Quit: Leaving). 21:07:39 i didn't like termux that much for some reason i fail to remember 21:07:53 maybe because of the softkeys or the colors or something like that 21:08:07 but the url handling of juicessh is the worst i've ever seen 21:08:14 even connectbot did it better 21:12:18 The default colors had that thing where the "dark blue" is very light. 21:13:19 But that was just a matter of copying my normal set of colors into ~/.termux/colors.properties on the phone. 21:15:56 The softkeys are also configurable, I set them to a multi-row layout pretty similar to what I had in JuiceSSH (esc, /, -, home, up, end, pageup on top row; tab, ctrl, alt, left, down, right, pagedown on bottom). 21:17:02 One thing that seems a bit wonky is that when you swipe the softkeys to switch to the "input a line of text using the normal Android text input" mode, it also seems to always treat that as a keypress of whatever key you start the swipe from. 21:17:50 Also the URL handling isn't that great either, there's a long-press "select URL" option but it doesn't consider # a URL character or some-such. 21:18:44 I like the volume key shortcuts. (Holding volume down acts like holding control down, and holding volume up turns wasd into arrows.) 21:18:52 -!- imode has joined. 21:23:43 Can you configure the URL characters and schemes? 21:26:09 Not via a configuration file, as far as I can tell. You could always just edit the source and build the app, though, it's open source. 21:26:25 The relevant logic would seem to be here: https://github.com/termux/termux-app/blob/master/app/src/main/java/com/termux/app/TermuxActivity.java#L676 21:31:51 -!- imode has quit (Ping timeout: 264 seconds). 21:34:37 We can see that some schemes are missing, such as "news" and "nntp" and "ssh" and "magnet". Also, the "news" and "magnet" schemes do not use // after the colon. And, yes it does looks like it doesn't include # as a URL character, but it ought to do; even that URL linking to the source code has it, and in many other HTTP(S) URLs it will be common, so it should be included. 21:38:05 -!- xkapastel has quit (Quit: Connection closed for inactivity). 22:25:51 -!- arseniiv has quit (Ping timeout: 264 seconds). 23:03:40 -!- LKoen has quit (Quit: “It’s only logical.
