+NOTE Q: Do you have any suggestions for interactive debugging of Julia code in Emacs?
+
+00:00.089 --> 00:00.829
+... answer to that. I, I think the infrastructure for an
+
+00:01.509 --> 00:14.192
+ecosystem in Julia in general is as mature as other
+
+00:01.509 --> 00:14.192
+languages, and even debugger infiltrator themselves are
+
+00:01.509 --> 00:14.192
+not particularly well developed. And so I don't think
+
+00:15.853 --> 00:19.214
+there's much we can do about that right now. I think that it's
+
+00:21.570 --> 00:28.057
+unfortunate that most of the development for these type of
+
+00:21.570 --> 00:28.057
+tools is tightly linked to VS code. But even there, I don't
+
+00:29.218 --> 00:36.225
+think that there's much done in terms of interactive
+
+00:29.218 --> 00:36.225
+debugging. So I, yeah, I think this has to be worked on mostly
+
+00:36.866 --> 00:43.213
+on the Julia side first. And then probably Emacs can get
+
+00:43.820 --> 00:48.303
+something out of that. I know that there's development in
+
+00:49.183 --> 00:57.728
+debugger.jl itself for future releases to make it at least
+
+00:49.183 --> 00:57.728
+faster and more stable. But yeah, I think we're not there as
+
+00:58.809 --> 01:03.852
+Julia community itself. So let alone Emacs, integration
+
+01:04.192 --> 01:07.234
+with Emacs. The way I personally debug is mostly using,
+
+01:08.286 --> 01:15.508
+well, debugger and infiltrator with Julia REPL mode in
+
+NOTE Q: Can you call out something that Julia has that Emacs does not, and which could benefit Emacs?
+
+01:08.286 --> 01:15.508
+Emacs. The second question, can you call out something that
+
+01:18.009 --> 01:24.891
+Julia has that Emacs does not and which could benefit Emacs?
+
+01:26.852 --> 01:27.852
+Nothing stands out to me except the usual multi-threading
+
+01:28.848 --> 01:32.552
+and things like this. I don't necessarily see something
+
+01:33.432 --> 01:46.783
+that Julia has going on that DMX doesn't have, but I see some
+
+01:33.432 --> 01:46.783
+differences and approaches that I think are important,
+
+01:33.432 --> 01:46.783
+like the community. I think Julia is a very active and tight
+
+01:47.384 --> 01:50.266
+community. Julia uses Slack and is very, very active. I
+
+01:54.093 --> 01:57.736
+think he might say something like that, but it's maybe more
+
+01:54.093 --> 01:57.736
+on Reddit, IRC. JuliaCon is big and brings together lots and
+
+01:59.078 --> 02:02.381
+lots of people. And I think the sense of community is really
+
+02:03.221 --> 02:05.263
+powerful. It's very easy to essentially meet people that
+
+02:06.364 --> 02:16.834
+are interested in what we're building and interested in
+
+02:06.364 --> 02:16.834
+what we're doing and interested in Julian, our, you know,
+
+02:06.364 --> 02:16.834
+hacker spirit. I think Emacs is a very strong community.
+
+02:21.228 --> 02:26.151
+We're here on a Saturday talking about Emacs, which again
+
+02:21.228 --> 02:26.151
+proves that we are doing this. But I'd like to emphasize that
+
+02:27.192 --> 02:35.696
+the community is a really important aspect in Julia that I
+
+02:27.192 --> 02:35.696
+think we should double down on our side. The next question is
+
+NOTE Q: Is there a way to use lisp syntax with Julia, like hy for python or lisp flavoured erlang?
+
+02:36.797 --> 02:44.841
+about Lisp syntax with Julia, like what we can do in Python.
+
+02:48.038 --> 02:53.180
+I don't think that's, I don't, I am not aware of any package
+
+02:48.038 --> 02:53.180
+that does that. I would bet that there's something there. I
+
+02:56.722 --> 02:58.063
+think that that's possible. Indeed, there used to be a Lisp
+
+02:59.243 --> 03:07.027
+interpreter in Julia itself until the latest release. The
+
+03:07.647 --> 03:12.229
+syntax parsing was done with a Lisp, it was called TemtoList
+
+03:07.647 --> 03:12.229
+indeed. I think this got rid, get rid of this for our more
+
+03:16.124 --> 03:23.489
+Julia-based solution that is faster and with better code
+
+03:16.124 --> 03:23.489
+provenance. I think that it should be possible to use the
+
+03:25.430 --> 03:35.437
+metaprogramming features in Julia to change the structure
+
+03:25.430 --> 03:35.437
+of your syntax to be a Lispy syntax. I do want to emphasize
+
+03:36.238 --> 00:03:44.664
+that Julia is heavily inspired by Lisp, so I wouldn't be
+
+03:36.238 --> 03:44.664
+surprised if if something like this were possible.
+
+03:49.309 --> 00:03:51.167
+I have tried Julia Snail.
+
+NOTE Q: Have you tried the Julia Snail package for Emacs? It tries to be like SLY/SLIME for Common Lisp.
+
+00:03:51.168 --> 00:03:51.070
+So the next question is about Julia
+
+03:51.270 --> 03:52.712
+Snail. I found Julia REPL to be a little bit easier to set up
+
+03:53.312 --> 03:58.436
+and use. So I just settled on that. I should maybe revisit
+
+04:00.918 --> 04:03.480
+that. In particular, I use the Julia REPL with the vterm
+
+04:03.720 --> 04:11.406
+backend, which essentially makes a companion REPL to my
+
+04:03.720 --> 04:11.406
+scripts. And that works for me. I do think that the tooling
+
+04:15.638 --> 04:16.518
+uh, could be improved. I think there is definitely much room
+
+04:17.399 --> 04:22.040
+and I would like to see improvement in that area. Um, and, uh,
+
+NOTE Q: Is there a data inspector for a Julia REPL available that you can use in Emacs?
+
+04:22.940 --> 04:28.322
+so we have data inspector for Julia REPL.
+
+04:32.043 --> 04:34.784
+I don't think so. I don't, is there any data inspector
+
+04:34.804 --> 04:39.826
+in for, for the Julia REPL that we can use in Emacs?
+
+04:43.223 --> 00:04:43.489
+I'm not sure. I don't think so.
+
+00:04:44.840 --> 00:04:47.839
+I think the way I look at data is
+
+00:04:47.840 --> 00:04:50.519
+essentially ignoring Emacs when encoded. It's just using the
+
+00:04:50.520 --> 00:04:54.759
+REPL. And again, with Julia REPL. So I'm not aware of any
+
+00:04:54.760 --> 00:04:57.720
+specialized tool And again, maybe this is, again, a good
+
+04:58.652 --> 05:05.595
+moment to emphasize that tooling, the Julia community
+
+04:58.652 --> 05:05.595
+clusters around VS Code. And there is tools like the, pretty
+
+05:06.315 --> 05:11.578
+much all the work with VS Code, unfortunately. And while
+
+05:12.578 --> 05:21.242
+there's a very, very decent Julia mode and Julia repo mode
+
+05:12.578 --> 05:21.242
+and Julia snail, there's definitely, definitely room for
+
+05:12.578 --> 05:21.242
+improvement.
+
+NOTE Q: Have you tried literate programming Julia (using Org babel or some other means) in Emacs?
+
+05:24.443 --> 05:28.145
+Next, we have a question about literate programming in
+
+05:24.443 --> 05:28.145
+Julia. I haven't done much of it with Org Babel or
+
+05:29.505 --> 05:32.906
+anything else. I haven't done much of it. I can say that Julia
+
+05:35.827 --> 05:46.070
+has developed a new iteration of notebooks called Pluto.
+
+05:46.090 --> 05:48.471
+Here I'm thinking about Jupyter notebooks. The Pluto
+
+05:51.021 --> 06:02.988
+notebooks for Julia try to remove a bunch of the pain points
+
+05:51.021 --> 06:02.988
+that Jupyter notebooks have, meaning you cannot easily
+
+05:51.021 --> 06:02.988
+commit them to Git or things like this.
+
+06:06.450 --> 06:09.152
+I haven't used them, but I know some people are very fond of
+
+06:06.450 --> 06:09.152
+them. And so I think that that's what some of the Julia
+
+06:09.872 --> 06:15.195
+community would use for notebooks. And I think they can
+
+06:15.315 --> 06:19.298
+interact with Emacs with no problem. And that would be a form
+
+06:20.974 --> 06:23.035
+of later programming. But if you can do it in Python, you can
+
+06:24.015 --> 06:27.696
+do it in Julia. I think there is no reason. And actually, you
+
+06:30.617 --> 06:38.719
+can take advantage of all this just-in-time or
+
+06:30.617 --> 06:38.719
+just-out-of-time compilation by keeping the same
+
+06:30.617 --> 06:38.719
+session. So I think it will be definitely a nice use case. So
+
+06:44.681 --> 06:47.222
+these are the questions that I see here. I'm going to scroll
+
+06:48.561 --> 06:54.486
+through the comments and see if there's something that I
+
+06:48.561 --> 06:54.486
+should say about comments. I'm excited people want to learn
+
+06:56.228 --> 06:57.669
+Julia. I have to say that if I want to do GPU computing
+
+06:58.990 --> 07:06.757
+nowadays, I find it much easier to do it with Julia than with
+
+06:58.990 --> 07:06.757
+CUDA. So I encourage people to look into that. And I do,
+
+07:11.758 --> 07:26.807
+again, I would like to share what makes me excited about
+
+07:11.758 --> 07:26.807
+Emacs, about this being open, being collaborative, being
+
+07:11.758 --> 07:26.807
+respectable with documentation is something that I find in
+
+07:11.758 --> 07:26.807
+Julia. So I think people that are excited about the same
+
+07:27.367 --> 07:35.192
+features will find a little bit of joy in working with Julia.
+
+07:38.214 --> 07:39.675
+I think I addressed what I have here. I don't know if there's
+
+07:40.189 --> 07:43.532
+anything else that I should add.
+
+07:51.718 --> 07:54.000
+It took me a minute to unmute there.
+
+00:07:54.040 --> 00:07:58.399
+No, I think that was awesome. And thank you so much.
+
+00:07:58.400 --> 00:08:00.399
+I guess I thought it would
+
+00:08:00.400 --> 00:08:06.559
+collapse that shared area on BBB, my mistake, on the stream,
+
+00:08:06.560 --> 00:08:12.399
+or I would have left it open. But in any case, no, I thought
+
+00:08:12.400 --> 00:08:15.079
+that was great. You did a great job of responding to all the
+
+00:08:15.080 --> 00:08:17.879
+questions and comments. And thank you again so much for your
+
+00:08:17.880 --> 00:08:20.920
+talk and getting us all excited to learn Julia. Thank you.
+
+08:24.094 --> 08:25.275
+Enjoy EmacsConf. And again, thanks so much for attending,
+
+08:25.335 --> 08:30.220
+for being EmacsConf. Thank you.
