[00:00.000 --> 00:07.640]  All good, I don't know if this is working, but it's green.
[00:07.640 --> 00:09.880]  Ah, look at you, crikey, thank you for coming.
[00:09.880 --> 00:12.560]  Look at this, excitable people.
[00:12.560 --> 00:16.440]  Collaboration, well, so here we are with Calabra.
[00:16.440 --> 00:19.440]  I hope this is what you want to hear.
[00:19.440 --> 00:21.640]  One of my concerns is that I've given similar talks
[00:21.640 --> 00:24.080]  in the past, so maybe we have lots of time
[00:24.080 --> 00:25.920]  for questions at the end.
[00:25.920 --> 00:31.600]  So I tried to do some different things this time.
[00:31.600 --> 00:34.280]  So one thing that we're really eager to do
[00:34.280 --> 00:37.680]  is to get Calabra online reused in lots of different places.
[00:37.680 --> 00:40.040]  That's lots of innovation going on out there.
[00:40.040 --> 00:41.600]  And lots of people have great ideas
[00:41.600 --> 00:45.560]  of how to use documents and make them look better on the web.
[00:45.560 --> 00:49.960]  And we would love to integrate with you to do that.
[00:49.960 --> 00:54.600]  So one of the things that we're really useful for
[00:54.600 --> 00:56.600]  is converting documents to different formats,
[00:56.600 --> 00:59.160]  which seems like an easy thing to do, you know?
[00:59.160 --> 01:00.760]  But it's really tough.
[01:00.760 --> 01:04.560]  And to wrap that up nicely for you,
[01:04.560 --> 01:06.960]  we have this beautiful rest endpoint.
[01:06.960 --> 01:09.000]  And it looks so simple, you know, you just do this curl
[01:09.000 --> 01:12.200]  command, brilliant, and you ignore certificates, OK,
[01:12.200 --> 01:15.040]  so you should remove that in deployment.
[01:15.040 --> 01:17.800]  And out of it, you get, well, what do you get?
[01:17.800 --> 01:20.080]  You get your text file turned into a .x.
[01:20.080 --> 01:21.320]  That's an easy one, right?
[01:21.320 --> 01:24.560]  But imagine you wanted to convert a PDF or, you know,
[01:24.560 --> 01:26.280]  a PPTX into a PDF.
[01:26.280 --> 01:29.680]  Or a very common request is converting PPTX
[01:29.680 --> 01:32.720]  into animated SVG.
[01:32.720 --> 01:33.880]  So we can do that very nicely.
[01:33.880 --> 01:35.520]  We can produce XHGML out of it.
[01:35.520 --> 01:37.040]  You can run in your browser.
[01:37.040 --> 01:38.320]  That's actually how Calabra online
[01:38.320 --> 01:39.680]  does its presentation thing.
[01:39.680 --> 01:41.760]  So you can get animations and presentations.
[01:41.760 --> 01:43.760]  You can understand the structure
[01:43.760 --> 01:48.480]  of your arbitrarily horrible, say, binary PowerPoint file.
[01:48.480 --> 01:49.680]  And you can dump that into something.
[01:49.720 --> 01:52.000]  You can parse and read and interpret and mash up
[01:52.000 --> 01:54.040]  and do cool stuff with.
[01:54.040 --> 01:55.760]  And the good news about that is that, well,
[01:55.760 --> 01:59.640]  say, people do this already in lots of horrible ways.
[01:59.640 --> 02:01.440]  So I will pick on someone.
[02:01.440 --> 02:03.840]  I don't know, is there any?
[02:03.840 --> 02:05.200]  Who do we have in the room?
[02:05.200 --> 02:06.440]  OK, let me think.
[02:06.440 --> 02:10.040]  What integration do I particularly like?
[02:10.040 --> 02:11.800]  So there is an unnamed open source project.
[02:11.800 --> 02:14.440]  And when it tries to convert its files,
[02:14.440 --> 02:18.720]  to show them in its jitsie-like, remarkably jitsie-like,
[02:18.760 --> 02:20.200]  a video, no, not jitsie.
[02:20.200 --> 02:21.240]  I forget.
[02:21.240 --> 02:23.200]  One of these video conferencing systems, big blue button,
[02:23.200 --> 02:24.680]  let's call it.
[02:24.680 --> 02:26.320]  It essentially has a shell script.
[02:26.320 --> 02:29.400]  And all of the good, beautiful software architecture
[02:29.400 --> 02:32.080]  stops at the point you want to convert a document.
[02:32.080 --> 02:35.480]  And it launches a shell script, which starts a Docker image,
[02:35.480 --> 02:37.760]  which then launches another shell script in the Docker image
[02:37.760 --> 02:40.680]  that copies a file into it with some horrible command
[02:40.680 --> 02:43.640]  that then converts it via another shell script.
[02:43.640 --> 02:47.800]  It launches an Office Suite that sits and talks to a RPC.
[02:47.800 --> 02:50.640]  And then it's just absolute horror.
[02:50.640 --> 02:53.520]  And if any of this hangs, or dies, or crashes, or burns,
[02:53.520 --> 02:56.760]  or uses more CPU, or finds that one document that
[02:56.760 --> 02:58.640]  has a real problem, you're just doomed.
[02:58.640 --> 03:02.560]  You have to write all of this lifecycle management nightmare.
[03:02.560 --> 03:04.640]  And the good news is, with our beautiful API,
[03:04.640 --> 03:06.840]  you don't need to care about any of that.
[03:06.840 --> 03:08.360]  Deploy the Docker image, job done.
[03:08.360 --> 03:09.960]  If it's too big, we'll time out.
[03:09.960 --> 03:11.920]  If it's too horrible, we'll tell you.
[03:11.920 --> 03:13.920]  And it's all done for you.
[03:13.920 --> 03:15.920]  So that's kind of good if you want the whole document.
[03:15.920 --> 03:19.040]  Often, though, people have enterprise, file sync, and share.
[03:19.040 --> 03:21.000]  They want to see their document.
[03:21.000 --> 03:23.480]  They're fed up of seeing an icon.
[03:23.480 --> 03:25.440]  They want to see what's inside it.
[03:25.440 --> 03:27.240]  So again, we can convert your document
[03:27.240 --> 03:29.840]  to an easy thumbnail, very trivially.
[03:29.840 --> 03:30.520]  Nice big image.
[03:30.520 --> 03:33.520]  You can shrink it down to whatever size you like.
[03:33.520 --> 03:35.720]  And that's pretty good.
[03:35.720 --> 03:38.200]  So we're really eager that people use it everywhere.
[03:38.200 --> 03:40.840]  And so we've written most of the work for you already,
[03:40.840 --> 03:42.240]  so you can use it.
[03:42.240 --> 03:45.440]  I think it's a patchy license, some really liberal.
[03:45.440 --> 03:47.800]  I'm more of a copy-left guy, but at least I understand.
[03:47.800 --> 03:48.800]  Other people aren't.
[03:48.800 --> 03:53.960]  So in the language of choice, we probably missed Ruby.
[03:53.960 --> 03:57.320]  I'm going to get in trouble with Neil later.
[03:57.320 --> 03:58.760]  But there you go.
[03:58.760 --> 04:00.600]  And we've done a whole lot of features recently.
[04:00.600 --> 04:03.120]  So one of them I was really surprised and encouraged.
[04:03.120 --> 04:06.280]  I was talking to someone from a European office
[04:06.280 --> 04:07.880]  full of lawyers earlier.
[04:07.880 --> 04:11.720]  And you wouldn't believe it, but they really love citations.
[04:11.720 --> 04:13.200]  They're all court cases, of course.
[04:13.200 --> 04:15.320]  I always think academic citations.
[04:15.320 --> 04:17.880]  But referring to other legal cases
[04:17.880 --> 04:20.640]  is this massive, worldwide web of knowledge
[04:20.640 --> 04:21.920]  about what's fair.
[04:21.920 --> 04:24.360]  And anyway, so we've done lots of things with Zotero.
[04:24.360 --> 04:25.760]  So one of the things that you can do,
[04:25.760 --> 04:28.320]  if you have a collaboration online integration now,
[04:28.320 --> 04:30.120]  is just to push.
[04:30.120 --> 04:35.040]  We added all this citation stuff in the toolbar here.
[04:35.040 --> 04:36.360]  And NextCloud implemented this.
[04:36.360 --> 04:38.640]  And all you need to do is provide a box somewhere
[04:38.640 --> 04:40.680]  that you can set this API key.
[04:40.680 --> 04:44.040]  So Zotero have a very nice REST API.
[04:44.080 --> 04:48.000]  And then we plug into that, and you send us this.
[04:48.000 --> 04:49.840]  We had this user private info.
[04:49.840 --> 04:52.440]  So you have a user info which has things like avatars
[04:52.440 --> 04:54.560]  and extended information about users
[04:54.560 --> 04:55.840]  that we send to everyone in the UI.
[04:55.840 --> 04:57.960]  We thought it was best not to send your private key
[04:57.960 --> 04:58.720]  to everyone.
[04:58.720 --> 05:01.720]  So we added this extra tag, user private info.
[05:01.720 --> 05:04.880]  And so when you connect to CollaborOnline
[05:04.880 --> 05:07.880]  and embed it in your iFrame, you need three methods.
[05:07.880 --> 05:11.640]  Get, so we can get the file and show it and render it.
[05:11.640 --> 05:13.760]  And then a post so we can send it back again
[05:13.760 --> 05:14.600]  when we've edited it.
[05:14.600 --> 05:16.000]  So that's the save.
[05:16.000 --> 05:17.880]  And then there's a check file info.
[05:17.880 --> 05:19.600]  And that basically tells us about you.
[05:19.600 --> 05:21.280]  So who is this person?
[05:21.280 --> 05:24.640]  We've got a path thing, a URL for the document.
[05:24.640 --> 05:28.920]  And we've got an opaque identification password to token.
[05:28.920 --> 05:29.880]  But what's their name?
[05:29.880 --> 05:30.720]  Tell me their name.
[05:30.720 --> 05:34.080]  Tell me what they look like, their avatar and this sort of thing.
[05:34.080 --> 05:36.560]  And so you just send this back there and bingo.
[05:36.560 --> 05:38.520]  Suddenly you have beautiful integration
[05:38.520 --> 05:41.640]  with all of your citation libraries.
[05:41.640 --> 05:44.760]  You don't need to run a Java app on the side and then talk.
[05:44.760 --> 05:46.800]  It just works really nicely.
[05:46.800 --> 05:50.080]  And updates all of your citations beautifully
[05:50.080 --> 05:51.120]  with a familiar interface.
[05:51.120 --> 05:52.880]  So that's kind of nice.
[05:52.880 --> 05:56.000]  That's a way of integrating two things together
[05:56.000 --> 05:59.400]  through a very, very simple REST API into a nice UI.
[06:01.840 --> 06:04.040]  Yeah, so language tool is something else I love.
[06:04.040 --> 06:07.320]  I don't know if Daniel's, he's probably a rich man.
[06:07.320 --> 06:11.000]  Grammarly has set a price point for,
[06:11.040 --> 06:12.600]  does anyone get Grammarly adverts?
[06:12.600 --> 06:13.560]  Does anyone watch YouTube?
[06:13.560 --> 06:15.320]  Has been plagued by, yeah.
[06:15.320 --> 06:18.920]  So there are many ways to create value in the world.
[06:18.920 --> 06:20.880]  One of them is, of course, to create value.
[06:20.880 --> 06:23.440]  The other is to tell people you've created value.
[06:23.440 --> 06:27.240]  And I think often as engineers we forget to tell people
[06:27.240 --> 06:28.400]  that we've created the value.
[06:28.400 --> 06:29.240]  That's the problem.
[06:29.240 --> 06:32.000]  We do it all and then there's no marketing.
[06:32.000 --> 06:34.240]  I think Grammarly is probably the extreme example
[06:34.240 --> 06:37.600]  of marketing versus value.
[06:37.600 --> 06:41.240]  But anyway, so they can sell somehow for 30 bucks a month,
[06:41.240 --> 06:43.440]  50 bucks a month, something like that,
[06:43.440 --> 06:45.520]  a subscription to their web grammar checker
[06:45.520 --> 06:48.240]  that sends all your information to someone else
[06:48.240 --> 06:52.960]  and sends it back with grammar checking, which is great.
[06:52.960 --> 06:55.200]  But because they've set the price point,
[06:55.200 --> 06:56.600]  there's a great company in Germany,
[06:56.600 --> 06:58.600]  I think based in Potsdam, that make,
[06:58.600 --> 07:00.720]  well, they already made an open source grammar checker.
[07:00.720 --> 07:03.120]  They've done the whole create the value bit.
[07:03.120 --> 07:06.160]  And so, but they now sell these lovely plugins to people
[07:06.240 --> 07:08.200]  and you can fit for much less money,
[07:08.200 --> 07:10.280]  get a better open source product
[07:10.280 --> 07:13.320]  and they have some of those nice AI things in there.
[07:13.320 --> 07:14.680]  And AI is cool.
[07:14.680 --> 07:17.760]  Of course, for checking an ISBN is valid,
[07:17.760 --> 07:21.120]  probably not the best use of AI, I might argue.
[07:21.120 --> 07:22.840]  But on the other hand, sentence structure
[07:22.840 --> 07:26.920]  and human language, that can be pretty cool.
[07:26.920 --> 07:28.840]  So, they're taking on Grammarly
[07:28.840 --> 07:29.960]  and the nice thing about that, of course,
[07:29.960 --> 07:30.960]  is you can get a docker image
[07:30.960 --> 07:34.560]  and you can deploy that in your Kubernetes, whatever
[07:34.560 --> 07:36.480]  and connect it up to a collaborate line.
[07:36.480 --> 07:39.160]  So, all of your grammar checking stays in-house.
[07:39.160 --> 07:42.120]  So, you get the benefit of all of that goodness
[07:42.120 --> 07:45.600]  and from a European free software company, I love it.
[07:45.600 --> 07:48.440]  And they're doing well and they're growing really nicely.
[07:48.440 --> 07:51.160]  So, nice to see that happen.
[07:51.160 --> 07:52.600]  Very easy to set up.
[07:52.600 --> 07:54.600]  And they even document the API nicely,
[07:54.600 --> 07:55.760]  which is kind of cool.
[07:55.760 --> 07:58.760]  So, you can see all of the number of features
[07:58.760 --> 08:03.520]  exposed in some of the JSON API they have at that URL.
[08:03.560 --> 08:04.680]  But again, very simple endpoints.
[08:04.680 --> 08:06.840]  You just send your stuff to check
[08:06.840 --> 08:08.840]  and you get some answers back and we show it.
[08:08.840 --> 08:11.800]  And then, of course, you can configure that as you like
[08:11.800 --> 08:13.400]  and they have a web service.
[08:13.400 --> 08:15.040]  I mean, another example of just sending text
[08:15.040 --> 08:17.240]  and getting text back is our deep integration.
[08:17.240 --> 08:21.320]  So, another easy thing there that's often useful for people.
[08:22.880 --> 08:27.080]  And, yeah, it's a bit interesting this.
[08:27.080 --> 08:29.880]  So, obviously, they want to try and retain formatting,
[08:29.880 --> 08:31.920]  which is probably one of the big advantages
[08:32.920 --> 08:35.320]  of pasting it into your web browser.
[08:35.320 --> 08:37.800]  But you can buy an enterprise key for DeepL and use that,
[08:37.800 --> 08:40.400]  but you're not going to have it on-premise, I guess.
[08:41.400 --> 08:44.000]  And then, trying to really get styles through HTML
[08:44.000 --> 08:46.560]  and map them back properly is more challenging
[08:46.560 --> 08:47.840]  than you might imagine.
[08:47.840 --> 08:49.120]  And we haven't done a very good job of it.
[08:49.120 --> 08:50.480]  So, if anyone wants to improve that,
[08:50.480 --> 08:53.440]  they're very welcome to come and contribute.
[08:53.440 --> 08:56.240]  But I think this idea of ask the computer
[08:56.240 --> 08:57.640]  to improve my documents and stuff,
[08:57.640 --> 09:01.400]  that interaction thing is there and working nicely.
[09:01.400 --> 09:03.000]  And there's lots of easy, low-hanging fruit
[09:03.000 --> 09:05.800]  if people want to help do cool stuff.
[09:07.520 --> 09:09.800]  So, one of the other things we try and do
[09:09.800 --> 09:12.120]  is we try and integrate outside the iframe.
[09:13.400 --> 09:15.920]  It's interesting. So, you create virtualization, for example,
[09:15.920 --> 09:18.480]  and almost all of the interesting thing about virtualization
[09:18.480 --> 09:20.280]  is the bit that isn't virtualized, you know,
[09:20.280 --> 09:21.840]  the bit where you can punch through the magic
[09:21.840 --> 09:25.280]  to not virtualize something and run the command inside it.
[09:25.280 --> 09:28.560]  Anyway, so, similarly with us,
[09:28.600 --> 09:31.120]  you know, the integration is probably
[09:31.120 --> 09:33.280]  the most interesting bit around the edge.
[09:33.280 --> 09:35.600]  And it's much the best if you can do that.
[09:35.600 --> 09:37.720]  So, we've written a huge SDK so that you're,
[09:37.720 --> 09:40.280]  it's easy to do, which you can see online.
[09:41.800 --> 09:44.480]  And so, when you save as, it seems easy to save as, right?
[09:44.480 --> 09:45.680]  But I just explained to you how it works.
[09:45.680 --> 09:47.120]  You know, you do a get and you do a post
[09:47.120 --> 09:49.000]  and that's kind of easy for us.
[09:49.000 --> 09:51.280]  But if you want to save it as something else,
[09:51.280 --> 09:52.920]  that's more tricky.
[09:52.920 --> 09:55.240]  So, but yet, people kind of want that
[09:55.240 --> 09:56.280]  if they're editing a document.
[09:56.280 --> 09:59.120]  They, you know, often people load a document
[09:59.120 --> 10:01.160]  and they continually save it as through its lifetime.
[10:01.160 --> 10:05.360]  So, the document you get actually started in 1995,
[10:05.360 --> 10:07.760]  you know, and it's been saved as ever since, you know,
[10:07.760 --> 10:11.640]  with a nice template and the WMF preview of Windows
[10:11.640 --> 10:14.320]  metafile in the top right corner and all of that good stuff.
[10:14.320 --> 10:16.240]  And often we see the macros in it.
[10:16.240 --> 10:17.840]  I mean, we're analyzing government macros
[10:17.840 --> 10:20.920]  and we routinely see like the Windows,
[10:20.920 --> 10:25.240]  the Office 95 macro API had a compatibility
[10:25.240 --> 10:28.080]  when Office 97 arrived and we're still seeing that in macros,
[10:28.080 --> 10:31.440]  you know, the word basic dot something thing.
[10:31.440 --> 10:32.440]  Just extraordinary.
[10:32.440 --> 10:34.200]  Anyway, save as is used.
[10:34.200 --> 10:35.880]  So, we should do that.
[10:35.880 --> 10:36.760]  I talked very quickly.
[10:36.760 --> 10:37.800]  Who has got lost?
[10:37.800 --> 10:39.480]  Does anyone, you know, no?
[10:39.480 --> 10:40.320]  I'm sorry.
[10:40.320 --> 10:42.600]  Okay, so we need a file picker.
[10:42.600 --> 10:43.440]  So, how are we going to get that?
[10:43.440 --> 10:46.360]  Well, I mentioned this check file info thing
[10:46.360 --> 10:48.840]  that tells us what you can cope with.
[10:48.840 --> 10:51.120]  And if you say, well, we can do insert remote image
[10:51.120 --> 10:53.400]  and we can do this write relative thing,
[10:54.360 --> 10:56.360]  then we'll send you a post message when you click save as.
[10:56.360 --> 10:58.120]  We send a post message outside the frame saying,
[10:58.120 --> 11:01.560]  hey, we want a graphic from somewhere, you know?
[11:01.560 --> 11:03.160]  And then you can do what you like.
[11:03.160 --> 11:06.360]  You pop up your nice file picker, come arbitrary,
[11:06.360 --> 11:08.840]  image creator, ASCII art, you know, whatever thing.
[11:08.840 --> 11:10.280]  We don't care.
[11:10.280 --> 11:12.920]  And when you're done, send us this action insert graphic
[11:12.920 --> 11:15.160]  and just a URL to it and we'll put it in the document.
[11:15.160 --> 11:16.120]  That's kind of cool.
[11:16.120 --> 11:19.160]  Or we'll save as and reload and, you know,
[11:20.120 --> 11:23.720]  create a window for the new document.
[11:23.720 --> 11:25.880]  So that's really useful and easy to do.
[11:25.880 --> 11:27.280]  And we're using, I think, the same hooks
[11:27.280 --> 11:28.760]  for our new export stuff.
[11:28.760 --> 11:32.400]  So there's a whole lot of work in accessible PDF creation
[11:32.400 --> 11:34.800]  and PDF UA and I mean, look at all these options.
[11:34.800 --> 11:37.400]  I mean, I hate options, but, you know,
[11:37.400 --> 11:38.680]  apparently you need all of these.
[11:38.680 --> 11:41.800]  So we've added loads of them recently and you'll be pleased.
[11:41.800 --> 11:45.120]  And of course, repub, it's very, very useful for accessibility.
[11:45.120 --> 11:48.800]  It's kind of an extended HTML, a dialect.
[11:49.040 --> 11:50.720]  So, you know, you can integrate easily
[11:50.720 --> 11:54.880]  and get all of this richness suddenly.
[11:54.880 --> 11:56.760]  One of our problems, of course, is that interoperability
[11:56.760 --> 12:00.440]  is really, really key in what we're doing.
[12:00.440 --> 12:02.960]  And people really care about that.
[12:02.960 --> 12:05.080]  And one of the challenges we have at the moment
[12:05.080 --> 12:09.800]  is our competition really is not great at interoperability.
[12:09.800 --> 12:11.720]  They're spoiled by interoperating with themselves
[12:11.720 --> 12:14.120]  a whole lot, which is easier.
[12:14.120 --> 12:17.160]  And so when we save, I mean, we love ODF, right?
[12:17.160 --> 12:20.400]  But if you save it in an ODF file, and, hey, that's good to see it,
[12:20.400 --> 12:22.840]  and then you sort of download it somewhere else
[12:22.840 --> 12:25.040]  and give it to someone on a Windows machine,
[12:25.040 --> 12:26.920]  like it's not, they'll load it in Word
[12:26.920 --> 12:28.880]  and it will completely mangle the document.
[12:28.880 --> 12:32.120]  You know, they even have a big list of the things they break.
[12:32.120 --> 12:34.520]  You know, there's a thousand pages.
[12:34.520 --> 12:36.520]  It's a very large document that explains
[12:36.520 --> 12:38.800]  all the things they don't do, you know, change tracking.
[12:38.800 --> 12:39.760]  I mean, why would you want that?
[12:39.760 --> 12:42.480]  You know, what kind of features?
[12:42.480 --> 12:44.680]  Anyway, so lots of it is dropped on the floor,
[12:44.680 --> 12:47.760]  which would be fine, because obviously that product is awful.
[12:47.760 --> 12:51.120]  But it's sad to be blamed, you know, for someone, I mean, like,
[12:51.120 --> 12:53.960]  you know, the user perception is your product doesn't interoperate.
[12:53.960 --> 12:55.360]  You're like, are you sure it's me?
[12:55.360 --> 12:56.520]  You know, like, I don't know.
[12:56.520 --> 13:00.120]  So, of course, if you use the DocX file format tragically,
[13:00.120 --> 13:03.520]  you know, we can interoperate better with the other world,
[13:03.520 --> 13:04.200]  which is a shame.
[13:04.200 --> 13:06.400]  But the good news is you shouldn't need to do that.
[13:06.400 --> 13:08.560]  You can use it all online in the browser
[13:08.560 --> 13:12.040]  and you can feel happy and relaxed knowing it's an ODF format
[13:12.080 --> 13:15.600]  on your server, and you have a full feature experience.
[13:15.600 --> 13:16.960]  But anyway, I was distracted.
[13:16.960 --> 13:19.600]  Remote font management, so that's all very good.
[13:19.600 --> 13:22.520]  But if you've ever written slides, what you'll notice is that,
[13:22.520 --> 13:25.000]  you know, that you change the wording of this line here
[13:25.000 --> 13:28.720]  until it just about fits in and doesn't wrap horribly, you know?
[13:28.720 --> 13:29.600]  And that's great.
[13:29.600 --> 13:33.200]  But of course, it's highly dependent on the font being used.
[13:33.200 --> 13:35.960]  And if you change the font, be it ever so slightly,
[13:35.960 --> 13:39.080]  you know, the text can grow and then everything looks awful.
[13:39.080 --> 13:40.480]  And of course, my slides look awful anyway,
[13:40.480 --> 13:41.640]  just because I'm a hacker.
[13:41.640 --> 13:43.960]  But other people have beautiful looking slides.
[13:43.960 --> 13:46.720]  And so anyway, we decided it was very useful
[13:46.720 --> 13:48.320]  to be able to configure fonts,
[13:48.320 --> 13:52.320]  and that brings a whole load of interesting problems.
[13:52.320 --> 13:54.560]  But anyway, to make this even easier,
[13:54.560 --> 13:55.880]  we have a remote configuration.
[13:55.880 --> 13:58.280]  So one of the things that's nice is to be able to deploy
[13:58.280 --> 14:01.240]  lots of images on Kubernetes and demand scale
[14:01.240 --> 14:03.400]  and more and more of these things.
[14:03.400 --> 14:05.920]  But it's a bit of a pain to configure them,
[14:05.920 --> 14:08.080]  and particularly for a large hoster or something.
[14:08.080 --> 14:10.440]  You know, you have customers that arrive quite regularly
[14:10.440 --> 14:12.160]  and add things, and how are you going to deal with that?
[14:12.160 --> 14:13.640]  And do you restart all of that?
[14:13.640 --> 14:14.520]  What do you do?
[14:14.520 --> 14:17.200]  So we have this remote configuration endpoint now.
[14:17.200 --> 14:19.480]  So you can cut a whole load of your config out.
[14:19.480 --> 14:21.960]  And collaboration, I would just go, hey, tell me my config.
[14:21.960 --> 14:22.680]  Has it changed?
[14:22.680 --> 14:24.640]  And then pull it every minute or so
[14:24.640 --> 14:28.800]  and update a whole subset of those settings to make it easier.
[14:28.800 --> 14:30.920]  And one of those courses is the font, font setting.
[14:30.920 --> 14:32.680]  So it's easy to have then a path to font.
[14:32.680 --> 14:34.720]  So if you have a file sync and share thing
[14:34.720 --> 14:37.160]  and you can manage files, you know, just create a folder
[14:37.160 --> 14:40.040]  and drop loads of fonts in it, and then we'll notice.
[14:40.080 --> 14:43.760]  And, you know, we just get this kind of JSON
[14:43.760 --> 14:48.160]  come out of that font endpoint, this thing we can figure in.
[14:48.160 --> 14:50.440]  That tells us where they are, and ideally some timestamps.
[14:50.440 --> 14:52.600]  So we don't, you know, continually fetch them.
[14:52.600 --> 14:54.880]  And then we can just build a whole set of fonts.
[14:54.880 --> 14:56.920]  And in the background, it's very funky,
[14:56.920 --> 14:58.600]  because we have a fork it.
[14:58.600 --> 15:01.400]  So you can't fork if you have threads.
[15:01.400 --> 15:02.920]  And it's kind of useful to have threads.
[15:02.920 --> 15:05.080]  So we initialize LibreOffice in what
[15:05.080 --> 15:07.760]  we call the fork it, whose job is just to fork.
[15:07.800 --> 15:10.560]  And we pre-initialize everything, load our configuration,
[15:10.560 --> 15:13.560]  and then we fork and copy on right huge amounts
[15:13.560 --> 15:15.120]  of our static data.
[15:15.120 --> 15:16.880]  So if you've started LibreOffice and thought, well,
[15:16.880 --> 15:18.120]  it took several seconds.
[15:18.120 --> 15:19.680]  What am I going to do online?
[15:19.680 --> 15:22.480]  Because that's the instant we fork within milliseconds
[15:22.480 --> 15:25.480]  and we have a document there ready to load and open.
[15:25.480 --> 15:27.440]  But the problem is it really needs all the fonts.
[15:27.440 --> 15:29.200]  And we really don't want to handle all of those fonts
[15:29.200 --> 15:30.240]  to the child processes.
[15:30.240 --> 15:32.520]  And we really control this very carefully
[15:32.520 --> 15:34.240]  from a security perspective.
[15:34.240 --> 15:37.720]  So anyway, after lots of work, we now restart this response.
[15:38.520 --> 15:42.120]  Load files and pass them in and patch lots of infrastructure.
[15:42.120 --> 15:43.560]  I was actually just talking to Leonard
[15:43.560 --> 15:45.400]  a few minutes ago about he was telling me,
[15:45.400 --> 15:46.440]  oh, you've got to mount PROC.
[15:46.440 --> 15:47.280]  You have to mount PROC.
[15:47.280 --> 15:48.120]  You'll get screwed over.
[15:48.120 --> 15:49.400]  You have to mount devices.
[15:49.400 --> 15:51.760]  Otherwise, something will go wrong in your stack somewhere.
[15:51.760 --> 15:54.520]  And we're like, yeah, well, we tested that.
[15:54.520 --> 15:57.560]  And we fixed and we patched around those things
[15:57.560 --> 15:59.960]  so that actually our jails have almost nothing in them.
[15:59.960 --> 16:04.680]  No PROC, only two devices in slash dev, no shell.
[16:04.680 --> 16:06.200]  They're pretty well locked down.
[16:06.200 --> 16:07.600]  So we like that.
[16:07.600 --> 16:09.200]  Oh, and then I've got a few minutes.
[16:09.200 --> 16:11.800]  I'll just show you a whole load of gratuitous features
[16:11.800 --> 16:14.160]  we've added just in case you like features.
[16:14.160 --> 16:16.600]  The users do, turns out.
[16:16.600 --> 16:18.760]  So I'm a big hater of the blockchain.
[16:18.760 --> 16:22.520]  But DevDAO actually sponsored some of this work.
[16:22.520 --> 16:23.160]  So we like that.
[16:23.160 --> 16:25.520]  And the European Commission as well.
[16:25.520 --> 16:27.840]  So getting our columns into our spreadsheets,
[16:27.840 --> 16:30.320]  lots of them has been happening.
[16:30.320 --> 16:32.080]  And it's got rid of this very annoying dialogue
[16:32.080 --> 16:34.840]  that played lots of users for a long time.
[16:34.840 --> 16:35.840]  So that's really cool.
[16:35.840 --> 16:37.120]  Oh, and there's even the proper credit.
[16:37.120 --> 16:38.800]  Well, NGIA DATSY.
[16:38.800 --> 16:40.800]  So the European Union Horizon Research Program
[16:40.800 --> 16:42.400]  is actually really cool.
[16:42.400 --> 16:45.280]  And anyone who has not knows about it,
[16:45.280 --> 16:47.960]  if you have a good idea, the traditional way
[16:47.960 --> 16:49.920]  of getting funding from the European Union
[16:49.920 --> 16:51.800]  was that if you have a really good idea,
[16:51.800 --> 16:55.480]  you need to find 15 other people across 27 countries
[16:55.480 --> 16:57.400]  and then try and persuade them all that their idea is
[16:57.400 --> 16:58.920]  the same thing and then get someone
[16:58.920 --> 17:00.320]  to write the proposal and submit it.
[17:00.320 --> 17:03.320]  And then you don't get it because it's all inconsistent.
[17:03.320 --> 17:08.440]  So the good thing about the NGIA DATSY, the Horizon Research
[17:08.440 --> 17:09.920]  thing, was that they said, hey, let's
[17:09.920 --> 17:11.480]  do something that's good for Europeans.
[17:11.480 --> 17:15.960]  And so they would just give money to single vision stuff.
[17:15.960 --> 17:17.960]  And our vision was, well, let's fix interoperability.
[17:17.960 --> 17:19.160]  So we did a lot of that.
[17:19.160 --> 17:20.440]  And they paid, which is awesome.
[17:20.440 --> 17:20.960]  Look at that.
[17:20.960 --> 17:25.920]  That's, yeah, it just makes life so much easier, doesn't it?
[17:25.920 --> 17:27.320]  And probably good for Europe as well.
[17:27.320 --> 17:31.720]  So anyway, say form controls, creating lots of nice rich text
[17:31.720 --> 17:34.720]  folders, much better PDF export with creating
[17:34.720 --> 17:37.120]  real, editable PDFs actually built into the product
[17:37.120 --> 17:40.800]  rather than having to layer things over the top afterwards.
[17:40.800 --> 17:42.440]  Starting to theme colors so that you
[17:42.440 --> 17:44.000]  can select different bits of your document
[17:44.000 --> 17:47.360]  and change the theme and see how that impacts the whole document.
[17:47.360 --> 17:50.480]  And we're doing lots of work here to extend that to writer
[17:50.480 --> 17:51.800]  and calc.
[17:51.800 --> 17:52.640]  Chart data tables.
[17:52.640 --> 17:54.120]  You wouldn't believe it, but these things
[17:54.120 --> 17:56.800]  at the bottom of charts are very popular in presentations.
[17:56.800 --> 17:59.360]  Some people like lines and other people like numbers.
[17:59.360 --> 18:01.720]  Now you can do both in the same thing.
[18:01.720 --> 18:03.640]  It's a key interoperability thing.
[18:03.640 --> 18:06.120]  And then also other random interop things,
[18:06.120 --> 18:08.720]  precisely anchoring your images and reflowing your text
[18:08.720 --> 18:12.040]  very nicely in the browser, improving our formula input
[18:12.040 --> 18:15.480]  bar, accessibility checker to try and find problems
[18:15.480 --> 18:18.040]  in your documents for the visually impaired,
[18:18.040 --> 18:19.920]  prettier dialogue functionality.
[18:19.920 --> 18:21.720]  So happening in the client side.
[18:21.720 --> 18:24.040]  And lots of this is now JavaScript in the client side
[18:24.040 --> 18:27.640]  to make it more accessible and performant.
[18:27.640 --> 18:31.160]  We completely reworked the tile serving thing.
[18:31.160 --> 18:33.920]  So instead of sending new tiles when things change,
[18:33.920 --> 18:35.600]  we send very small deltas of them.
[18:35.600 --> 18:37.760]  So we find the pixels that change,
[18:37.760 --> 18:39.800]  and then we Z-standard compress them.
[18:39.800 --> 18:43.200]  So we switch from big PNGs with even headers in them
[18:43.200 --> 18:48.720]  and crazy stuff to much smaller Z-standard compressed things.
[18:48.720 --> 18:49.560]  Thanks to Facebook.
[18:49.560 --> 18:53.040]  I just need to thank Facebook for helping us all get digital
[18:53.040 --> 18:53.960]  sovereignty back.
[18:53.960 --> 18:56.920]  That's important.
[18:56.960 --> 18:57.960]  Password options.
[18:57.960 --> 19:00.200]  So you can put passwords on your files
[19:00.200 --> 19:01.200]  and various attributes.
[19:01.200 --> 19:03.680]  Lots I've mentioned, the PDF things, embedded video
[19:03.680 --> 19:06.680]  playbacks, if you like that sort of thing.
[19:06.680 --> 19:08.640]  And the last silly idea, I think,
[19:08.640 --> 19:12.160]  in the few seconds I have left.
[19:12.160 --> 19:13.760]  So we've done a bit of a concept for running
[19:13.760 --> 19:15.080]  CollaborOnline in the browser.
[19:15.080 --> 19:16.840]  So when you go through your tunnel,
[19:16.840 --> 19:19.280]  and my hope is that tunnels get better connectivity.
[19:19.280 --> 19:22.600]  But you can then click a button and, in theory,
[19:22.600 --> 19:23.880]  run this thing offline.
[19:23.880 --> 19:26.240]  So we have a prototype now of CollaborOnline.
[19:26.240 --> 19:27.680]  If you're interested in that, there'll
[19:27.680 --> 19:30.040]  be talks in the LibreOffice track, which is, I suppose,
[19:30.040 --> 19:33.360]  somewhere nearby, that then allows you to edit offline.
[19:33.360 --> 19:35.320]  And there are a whole lot of interesting problems there.
[19:35.320 --> 19:38.160]  If you like wrestling with massive, multi-gigabyte
[19:38.160 --> 19:41.600]  linkages and horrible nightmares, do get involved with that.
[19:41.600 --> 19:43.000]  But there's a little prototype there
[19:43.000 --> 19:46.920]  that will allow you to work on that and play with WASM.
[19:46.920 --> 19:48.280]  So yeah, come and hack with us.
[19:48.280 --> 19:48.960]  We have HackFest.
[19:48.960 --> 19:50.600]  So there's a LibreOffice HackFest.
[19:50.600 --> 19:53.360]  If you're excited about LibreOffice, and you should be.
[19:53.360 --> 19:55.880]  The cool kids are all using LibreOffice technology.
[19:55.920 --> 19:58.120]  Come to our HackFest this Monday and Tuesday.
[19:58.120 --> 20:00.320]  Oh, we have a community dinner tonight with Pasta
[20:00.320 --> 20:02.720]  at the Business and Technology Incubator.
[20:02.720 --> 20:04.240]  And there's a great link there.
[20:04.240 --> 20:06.120]  If you take a photo of it, you'll have it for later,
[20:06.120 --> 20:06.800]  so you can come along.
[20:06.800 --> 20:09.480]  And beyond that, we're running a HackFest
[20:09.480 --> 20:13.200]  in Clare Corridor, Cambridge, in March 28 and 29,
[20:13.200 --> 20:16.040]  which is not only LibreOffice, but also CollaborOnline.
[20:16.040 --> 20:17.960]  And it would be lovely to see you there.
[20:17.960 --> 20:20.080]  If you want to come and stay in a beautiful Cambridge College
[20:20.080 --> 20:24.120]  and wine and dine at our expense and have some team building
[20:24.120 --> 20:25.680]  and get stuck into CollaborOnline,
[20:25.680 --> 20:26.920]  we'd love to have you with us.
[20:26.920 --> 20:28.220]  So thank you for your patience.
[20:28.220 --> 20:36.760]  Are there any questions?
[20:39.920 --> 20:40.800]  Yes, sir?
[20:40.800 --> 20:44.520]  When can we expect the chat-GPT integration with CollaborOn?
[20:44.520 --> 20:49.280]  Well, like I say, when can we expect chat-GPT integration
[20:49.280 --> 20:49.760]  with CollaborOn?
[20:49.760 --> 20:51.000]  I'm sorry, I have to repeat the question.
[20:51.000 --> 20:52.560]  Yes, so it's a really good question.
[20:52.560 --> 20:55.080]  Ultimately, you can select some text,
[20:55.080 --> 20:58.040]  and we can send that to you, and you can send it back quite
[20:58.040 --> 20:59.440]  easily.
[20:59.440 --> 21:01.680]  But yeah, I think AI brings a whole lot
[21:01.680 --> 21:03.800]  of interesting challenges.
[21:03.800 --> 21:07.600]  And I think, I don't know if you've looked at Office 365
[21:07.600 --> 21:09.960]  and the AI slide improver, which I obviously
[21:09.960 --> 21:12.440]  should have used.
[21:12.440 --> 21:14.440]  It makes your slides look pretty.
[21:14.440 --> 21:17.040]  But the question is, what are pretty slides?
[21:17.040 --> 21:20.240]  And the real problem in AI is, of course, the training data.
[21:20.240 --> 21:21.440]  And one of our problems is that we
[21:21.440 --> 21:23.720]  like this digital sovereign world where we don't spy on people
[21:23.720 --> 21:25.360]  all the time to work out what they're
[21:25.360 --> 21:26.960]  doing to their documents, right?
[21:26.960 --> 21:28.680]  So Microsoft doesn't have this problem.
[21:28.680 --> 21:31.880]  They have Office 365, and they're constantly watching, you know?
[21:31.880 --> 21:34.280]  So they know how to make pretty slides just
[21:34.280 --> 21:37.600]  by watching millions of people go, color's a bit.
[21:37.600 --> 21:40.000]  And also offering you options of different ways
[21:40.000 --> 21:44.800]  to break or improve your slide and seeing what you choose.
[21:44.800 --> 21:48.320]  So yeah, I mean, how do we build the data sets
[21:48.320 --> 21:51.120]  to let us do this in an open-source way?
[21:51.120 --> 21:53.240]  And I think AI is fantastically interesting.
[21:53.240 --> 21:54.680]  And Bradley, no doubt, will come up
[21:54.680 --> 21:58.720]  with the Aferro AI license, you know?
[21:58.720 --> 21:59.800]  I'm sure this is happening.
[21:59.800 --> 22:05.520]  Because the source is banal beyond belief in most AI things.
[22:05.520 --> 22:09.400]  It's the data and the training data and the model you build.
[22:09.400 --> 22:11.520]  So yeah, it would suck to be an open-source company.
[22:11.520 --> 22:13.040]  100% open-source code.
[22:13.040 --> 22:14.600]  It's just this massive binary blob
[22:14.600 --> 22:16.480]  that not even we understand that you have to buy,
[22:16.480 --> 22:18.280]  you know, to make it useful.
[22:18.280 --> 22:19.400]  So I don't know.
[22:19.400 --> 22:20.920]  We're working on the problem.
[22:20.920 --> 22:22.360]  And there are a lot of smart minds
[22:22.360 --> 22:24.760]  thinking about putting AI and keeping
[22:24.760 --> 22:26.280]  that sovereign and on-premise.
[22:26.280 --> 22:28.840]  But I don't have a perfect answer.
[22:28.840 --> 22:30.600]  But it's a fantastic question.
[22:30.600 --> 22:33.280]  And if you want to do chat, GPT, we should talk.
[22:33.280 --> 22:34.640]  You know, come and see me.
[22:34.640 --> 22:35.800]  I did not mention we're hiring people.
[22:35.800 --> 22:36.720]  I'm probably not supposed to.
[22:36.720 --> 22:38.240]  But we love C++ hackers.
[22:38.240 --> 22:41.040]  If you come and see me, you know, we're growing fast
[22:41.040 --> 22:42.000]  and doing some cool things.
[22:42.000 --> 22:44.120]  Other questions?
[22:44.120 --> 22:45.640]  Anyone at all?
[22:45.640 --> 22:46.120]  No?
[22:46.120 --> 22:46.680]  More?
[22:46.680 --> 22:48.640]  Yeah?
[22:48.680 --> 22:51.320]  Well, that's very good of you.
[22:51.320 --> 22:52.840]  Then come and see me afterwards if you want to chat.
[22:52.840 --> 22:53.320]  Please do.
[22:53.320 --> 22:53.960]  Thank you so much.
[22:53.960 --> 22:54.960]  Thank you very much.
[22:54.960 --> 22:55.960]  Thank you very much.
[22:55.960 --> 22:56.960]  Thank you very much.
[22:56.960 --> 22:57.960]  Thank you.
[22:57.960 --> 22:58.960]  Thank you very much.
[22:58.960 --> 22:59.960]  Thank you.
[22:59.960 --> 23:00.960]  Thank you.
