WEBVTT

00:00.000 --> 00:07.200
Okay, so we are live now. So hi, everyone. Sorry, we were doing some last minute verification

00:07.200 --> 00:12.720
with Blaine. We wanted to share screens, but somehow the Firefox gods are not in our favor

00:12.720 --> 00:15.640
today. So hi, Blaine. How are you doing?

00:15.640 --> 00:21.480
I'm doing great, Will. This has been a great conference. I've seen some talks this morning

00:21.480 --> 00:27.100
that are going to change my life. I just can't wait to start applying some of the packages

00:27.100 --> 00:28.100
I've learned about.

00:28.100 --> 00:33.240
That's amazing. And it's only day one. We've got more of this coming today, too.

00:33.240 --> 00:34.240
Exactly.

00:34.240 --> 00:38.000
So, Blaine, we haven't had the chance to tell you, but do you have the pad open on

00:38.000 --> 00:39.000
your end?

00:39.000 --> 00:40.000
Let's see.

00:40.000 --> 00:45.040
Oh, yes, because I asked you to close Firefox, so you don't have it. Do you need the URL,

00:45.040 --> 00:46.040
maybe?

00:46.040 --> 00:48.080
Yeah, that would be great.

00:48.080 --> 00:52.280
I will put it into BBB, the chat right on your left.

00:52.280 --> 00:58.200
Okay. I see it. So if I click on this and open a new window?

00:58.200 --> 01:00.520
Yes, don't worry about it.

01:00.520 --> 01:05.600
Okay. So I have some questions. Oh, that's fantastic. This is kind of a silly question,

01:05.600 --> 01:10.560
but I'm curious. Do you have a favorite color theme?

01:10.560 --> 01:21.120
So I do. I've been using a color theme that is sort of light green. It's from a set of

01:21.120 --> 01:29.760
themes that Prot put together and made available this fall on Melpa, and in some of the slides

01:29.760 --> 01:36.880
you'll see that I have this, like, white background, but I'm currently using a sort of a mint green

01:36.880 --> 01:45.240
color, which I find actually has great contrast, and I had to install some fonts for the Mac

01:45.240 --> 01:52.360
to be able to use that theme, but Prot provides detailed instructions, and it was pretty easy

01:52.360 --> 01:54.360
to do.

01:54.360 --> 02:03.960
Okay. Let's see. To your knowledge, so the second question is, to your knowledge, are

02:03.960 --> 02:09.000
recent coming security changes in Chrome going to impact browser extension?

02:09.000 --> 02:16.560
Oh, that's a great question. I, to be honest, I don't know. I'm not aware of that issue

02:16.560 --> 02:23.400
because I ran and I installed some extension I probably shouldn't have installed in Chrome

02:23.400 --> 02:30.120
a couple weeks ago, and I've been getting pop-up ads, and so I switched to Firefox,

02:30.120 --> 02:39.960
but so far I have used GhostText in a number of browsers. I can vouch that it works in

02:39.960 --> 02:50.120
Safari, Chrome, obviously Firefox, Brave, and then amongst the Firefox family of browsers

02:50.120 --> 02:56.240
there's WaterFox and IceCat. It works in those two.

02:56.240 --> 03:02.400
So if Chrome's security issues become a problem, then there are other browsers for which maybe

03:02.400 --> 03:07.960
that problem won't be an issue.

03:07.960 --> 03:14.580
Is this, a third question is, is this browser, is this browser agnostic, or do you have to

03:14.580 --> 03:17.760
use Chrome?

03:17.760 --> 03:25.460
That's a good question. So obviously, as you've seen that, or just heard, it works in a number

03:25.460 --> 03:30.480
of other browsers. There's probably at least ten other browsers in which it will work.

03:30.480 --> 03:35.840
So there's sort of three families of extensions, one for Safari, one for Firefox, and one for

03:35.840 --> 03:47.580
Chrome, and often one of those extensions will work in a different browser.

03:47.580 --> 03:53.060
You mentioned, fourth question is, you mentioned a couple other solutions to allow Emacs editing

03:53.060 --> 04:02.600
of text areas, pointers. Well, unfortunately, I didn't do my due diligence in researching

04:02.600 --> 04:07.000
those other solutions. I'm aware that there's something called Emacs Everywhere that's supposed

04:07.000 --> 04:13.840
to have a similar capability, but I haven't dug into using it, so I can't say anything

04:13.840 --> 04:14.840
about it.

04:14.840 --> 04:27.040
I'll have to say that. So because you're setting up a server from an editor, and you have this

04:27.040 --> 04:35.520
extension in a browser, things don't always mesh. You may have port 4001 occupied by some

04:35.520 --> 04:43.720
other server from Emacs or another application, and so you have to sort that out. That can

04:43.720 --> 04:49.360
happen from time to time. I've had trouble with the Emacs server sometimes using that

04:49.360 --> 04:57.800
port, but I think you can redirect that Emacs server to another port to avoid that issue.

04:57.800 --> 05:02.240
That would be the greatest difficulty is just getting the two sides talking to each other

05:02.240 --> 05:10.160
through the web socket, but once that's going, I use it every day, and I'll go for weeks

05:10.160 --> 05:16.560
without any issue, and then, of course, I'll be changing something about Emacs configuration

05:16.560 --> 05:22.520
where I'm turning on some new server that fires up when I start Emacs, and then I break

05:22.520 --> 05:28.760
it there, or something along those lines, but the great hazard of fiddling with your

05:28.760 --> 05:49.520
Emacs configuration, just a hazard of being an Emacs user. Let's see. Why not save text?

05:49.520 --> 05:56.120
So I have a fifth question, which is why not save text from Emacs? I would like to hear

05:56.120 --> 06:04.560
some solution to the issue I ran into. So if I am editing a document in a web browser

06:04.560 --> 06:13.200
and then via Emacs, and I save that to a document on disk, then I, okay, that's great if I'm

06:13.200 --> 06:19.020
not going to make any more changes, everything's fine, that works great, but if I then decide

06:19.020 --> 06:27.200
to make more changes in the browser, and then I try to save those changes, the copy on disk

06:27.200 --> 06:32.280
is out of sync with the copy in the browser, and I've had the connection break when I do

06:32.280 --> 06:42.080
that. So I heard that there might be a way of solving that problem. I'm not, but I have

06:42.080 --> 06:48.040
not implemented the solution. I forget what the suggestion was. Maybe somebody in the

06:48.040 --> 06:51.840
audience has an idea.

06:51.840 --> 06:56.760
Speaking of the audience, we have opened up the chat now, so if you want to join the current

06:56.760 --> 07:02.200
BBB Discord room in which we are and ask questions directly to Blaine, feel free to do so, otherwise

07:02.200 --> 07:05.840
we're still taking questions on the pad as long as we have them, although right now I

07:05.840 --> 07:10.120
think we have answered all of them. Am I wrong, Blaine, or did we answer all of them already?

07:10.120 --> 07:13.200
You're correct, we've answered all of them.

07:13.200 --> 07:18.120
So we're going to still discuss for about 2-3 minutes. If people want to add last questions

07:18.120 --> 07:23.360
to the pad, feel free to do so. If you want to join us in BBB, the link is at the top

07:23.360 --> 07:28.140
of the talk of Blaine, Euclid Maxco 2022. You know everything now. We are at the end

07:28.140 --> 07:33.640
of the day, and you can tell it's the end of the day because my accent is getting significantly

07:33.640 --> 07:40.840
Frencher as a result. It's not getting any better since last year, I think. I wish I

07:40.840 --> 07:44.760
could contribute, Blaine, more to your talk, but I feel like I'm way out of my league.

07:44.760 --> 07:50.280
I'm the guy who plays with Org on the side, and I tune into your talks every year, and

07:50.280 --> 07:54.840
I see molecules, and I see stuff that I can barely comprehend, and I feel very humbled

07:54.840 --> 07:56.840
as a result.

07:56.840 --> 08:03.320
Well, I'm just trying to make my talks kind of unique.

08:03.320 --> 08:07.960
You are succeeding amazingly well. It reminds me, have you been talking with John Kinchin

08:07.960 --> 08:15.680
or something? Because you seem to be evolving in seminal fields, in a way, with Emacs.

08:15.680 --> 08:26.160
I have been. I'm a fan of his. I have installed CyMax and his configuration for Emacs, but

08:26.160 --> 08:33.960
I haven't. I've just started poking around with it, and I've used his configuration.

08:33.960 --> 08:43.280
I've got it up and running, and I've used GhostText with it, and I was trying to tap

08:43.280 --> 08:49.880
into his OrgRef package, which is super powerful for managing bibliographies.

08:49.880 --> 08:50.880
Yeah.

08:50.880 --> 08:53.880
Yeah, he's very inspiring.

08:53.880 --> 08:59.880
I'm glad to hear you're very much inspired. Go on, please.

08:59.880 --> 09:05.280
He's very amazing. He's very accomplished in Emacs and a very accomplished teacher,

09:05.280 --> 09:11.160
and he has now, as you probably know, a series of videos on YouTube that he's been putting

09:11.160 --> 09:18.920
together about programming. So he's teaching students at Carnegie Mellon University how

09:18.920 --> 09:26.200
to program in Python via Emacs, and he has been sharing these videos on YouTube, and

09:26.200 --> 09:30.720
they're like just 20-minute videos, kind of short snippets, but you can learn a lot from

09:30.720 --> 09:33.480
them. It's really fantastic.

09:33.480 --> 09:39.240
It's an amazing journey, isn't it? You start from a field that has nothing to do whatsoever

09:39.240 --> 09:43.800
with Emacs, and yet you find yourself so attracted to the idea of programming and making your

09:43.800 --> 09:49.620
workflow easier that you end up actually transitioning into a little bit of a programming role or

09:49.620 --> 09:54.900
teaching programming role. I mean, I was studying literature. I was all well and good in my

09:54.900 --> 10:00.040
English faculty, and then I decided to say, oh yeah, let's try Emacs, and 10 years later

10:00.040 --> 10:06.160
I find myself spending more time working on Emacs than working on my literature papers.

10:06.160 --> 10:12.920
My history is that I developed a dozen years ago, started teaching students how to do molecular

10:12.920 --> 10:17.960
graphics, and then I got into Python programming to develop tools to make it easier for them

10:17.960 --> 10:22.680
to use molecular graphics, and then evolved into making these snippets available for a

10:22.680 --> 10:29.680
wide range of text editors that meant learning about – so I prepared these snippets for

10:29.680 --> 10:35.440
about 20 different text editors, leading ones, and of course I saved for the end Emacs. First

10:35.440 --> 10:42.800
I went through Vim and the month of hell of rewiring your brain to do the Vim key bindings

10:42.800 --> 10:51.920
and then on to Emacs, which I call the ultimate text editor, because there is no other text

10:51.920 --> 10:56.040
editor beyond Emacs. It's the end of the line.

10:56.040 --> 11:01.360
I absolve you for your herrings with Vim as a result of the last comment you just made.

11:01.360 --> 11:05.680
Actually, no, I have new write of that solution. I can agree to your solution. You'll have

11:05.680 --> 11:09.200
to ask RMS tomorrow.

11:09.200 --> 11:16.800
Well, I spent a year in evil mode, but I switched about half a year ago to just Emacs key bindings

11:16.800 --> 11:24.840
and bye-bye Vim. I use Vim when I log into remote servers and have to edit something

11:24.840 --> 11:30.720
really quick, but I've probably forgotten most of the key bindings. There's only about

11:30.720 --> 11:36.560
a dozen you really need to know to get the essential work done. But yeah, it's been

11:36.560 --> 11:37.560
quite a journey.

11:37.560 --> 11:45.160
Sorry for the interruption. We do have one question, a very simple question about what

11:45.160 --> 11:51.200
was the key binding for Linux Firefox. Do you have it on top of your mind?

11:51.200 --> 11:52.200
So Linux Firefox.

11:52.200 --> 11:57.240
I'm not sure what they're referring to as well, which is why I threw you this purple,

11:57.240 --> 11:59.240
hoping that it would make sense for you.

11:59.240 --> 12:00.240
It's Control-Shift-H.

12:00.240 --> 12:14.120
I hope this answers your questions. So I think Control-Shift-H, yes. Well Blaine, I see some

12:14.120 --> 12:18.120
people have joined on BBB, but no one with a microphone still. I will tide you at the

12:18.120 --> 12:21.560
end. We are reaching the end of the day. We are reaching closing remarks and I will be

12:21.560 --> 12:26.720
making a plea for more people to join with a microphone. Last year we had pretty much

12:26.720 --> 12:30.440
the same setting. We were opening the room afterwards and people were showing up with

12:30.440 --> 12:33.760
the microphones and we had lovely discussions. So in this year, it feels like everyone's

12:33.760 --> 12:38.940
a little shy, shouldn't you know? That's the whole point is for you to talk and for

12:38.940 --> 12:43.160
us all to listen. Well Blaine, that was very insightful. Thank you so much for both the

12:43.160 --> 12:44.960
presentation and the questions. Go on.

12:44.960 --> 12:51.200
We have a question in the panel on the left and blue button. So how long have I been using

12:51.200 --> 13:03.520
Emacs? I made a commitment to use it full-time about 18 months ago, maybe 20 months ago.

13:03.520 --> 13:09.240
So I'm a newbie. I'm still in the steep part of the learning curve.

13:09.240 --> 13:13.640
You just have to provide context for the people. Blaine presented something at the last year's

13:13.640 --> 13:19.440
EmacsConf and it was as impressive as this year's presentation. And afterwards he told

13:19.440 --> 13:23.760
us, oh yeah, I've been using Emacs for six months or so. And that's where everyone's

13:23.760 --> 13:28.920
jewels dropped to the floor because some people have been using Emacs for 10 years and we

13:28.920 --> 13:31.960
couldn't even imagine doing some of the stuff you're doing with it.

13:31.960 --> 13:33.960
Thank you.

13:33.960 --> 13:40.880
Do we have any other questions? I think that's pretty much it. I'm not seeing anything appear

13:40.880 --> 13:48.520
on the other screen. I think we're pretty much good. So Blaine, I'm not going to keep

13:48.520 --> 13:52.880
you any longer. We are probably going to bring this Q&A to a close. Thank you so much for

13:52.880 --> 13:59.880
all the answers. What are we going to do for the stream? We still have a talk going on

13:59.880 --> 14:05.960
on the dev channel currently. And then we'll be going to the closing remarks for the day

14:05.960 --> 14:10.680
at about 55 of the current hour. So we are going on a break for 20 to 25 minutes. So

14:10.680 --> 14:14.040
Blaine, sorry for keeping you off stage as I'm making the announcement, but it's the

14:14.040 --> 14:16.520
best way for people to see my face as I do it.

14:16.520 --> 14:20.800
Thank you very much, Leo. I appreciate it.

14:20.800 --> 14:26.720
And thank you so much for all your time and all your answers. I will be closing BBB now

14:26.720 --> 14:31.600
and we will put some music on and some announcements and see you at the top of the hour for the

14:31.600 --> 14:57.720
others or 55 rather than top of the hour. All right. Bye bye everyone. Bye bye Blaine.
