-00:00:52.239 --> 00:00:54.079 -little different from the previous - -00:00:54.079 --> 00:00:56.879 -talk I've gave you and different even - -00:00:56.879 --> 00:00:58.239 -from what nura gave you - -00:00:58.239 --> 00:01:00.480 -there's like uh scaling the mountain as - -00:01:00.480 --> 00:01:02.399 -far as difficulty is concerned and on - -00:01:02.399 --> 00:01:03.359 -this one - -00:01:03.359 --> 00:01:04.879 -I will be telling you about the - -00:01:04.879 --> 00:01:06.799 -technical aspects of orgrim - -00:01:06.799 --> 00:01:09.360 -because you know I've been telling you - -00:01:09.360 --> 00:01:11.119 -about the general philosophy - -00:01:11.119 --> 00:01:13.119 -of the notes and the general philosophy - -00:01:13.119 --> 00:01:14.560 -of organization - -00:01:14.560 --> 00:01:16.159 -but right now I really want to get into - -00:01:16.159 --> 00:01:18.479 -the nitty gritty about or grow - -00:01:18.479 --> 00:01:22.640 -so if we go in the git repository - -00:01:22.640 --> 00:01:25.759 -this at the very core is all grown and - -00:01:25.759 --> 00:01:27.920 -for some of you who have no experience - -00:01:27.920 --> 00:01:28.960 -whatsoever - -00:01:28.960 --> 00:01:31.280 -uh developing stuff or programming or - -00:01:31.280 --> 00:01:32.880 -anything along those lines - -00:01:32.880 --> 00:01:36.000 -this is how all the development around - -00:01:36.000 --> 00:01:36.720 -the world - -00:01:36.720 --> 00:01:40.000 -is working you have a repository a - -00:01:40.000 --> 00:01:42.159 -git repository where you have all the - -00:01:42.159 --> 00:01:44.399 -files all the libraries you're using - -00:01:44.399 --> 00:01:46.399 -all the programs all the commands - -00:01:46.399 --> 00:01:48.720 -everything is inside your files - -00:01:48.720 --> 00:01:52.240 -and in a way this is the organ project - -00:01:52.240 --> 00:01:53.759 -you can see that we have many files we - -00:01:53.759 --> 00:01:55.600 -have organ buffer capture compat - -00:01:55.600 --> 00:01:57.040 -completion dailies - -00:01:57.040 --> 00:02:00.399 -etc etc so - -00:02:00.399 --> 00:02:02.000 -before we dive a little deeper I just - -00:02:02.000 --> 00:02:04.079 -want to give you a lay of the land so to - -00:02:04.079 --> 00:02:04.640 -speak to - -00:02:04.640 --> 00:02:08.160 -to know where we're heading so - -00:02:08.160 --> 00:02:11.680 -orgro is built on top of old mode - -00:02:11.680 --> 00:02:15.599 -and org mode gives us plenty of tools - -00:02:15.599 --> 00:02:17.760 -to play around with the files I'm moving - -00:02:17.760 --> 00:02:18.800 -the glass I'm - -00:02:18.800 --> 00:02:20.080 -I'm starting to move my hands a little - -00:02:20.080 --> 00:02:21.360 -bit you know when I get excited about - -00:02:21.360 --> 00:02:22.959 -something I move my hand - -00:02:22.959 --> 00:02:26.640 -and then that stuff happens so - -00:02:26.640 --> 00:02:29.360 -in all chrome we have org mode and - -00:02:29.360 --> 00:02:31.360 -augment gives us plenty of tools which - -00:02:31.360 --> 00:02:33.360 -are incredibly useful - -00:02:33.360 --> 00:02:36.560 -for writing stuff so you know we already - -00:02:36.560 --> 00:02:37.440 -have the links - -00:02:37.440 --> 00:02:39.440 -we already have the hierarchy which is - -00:02:39.440 --> 00:02:40.560 -given by having - -00:02:40.560 --> 00:02:43.360 -trees within trees within trees we have - -00:02:43.360 --> 00:02:43.760 -uh - -00:02:43.760 --> 00:02:45.760 -quote blocks we have babel blocks we - -00:02:45.760 --> 00:02:48.000 -have so much stuff we have an arsenal of - -00:02:48.000 --> 00:02:49.680 -tools that have been developed - -00:02:49.680 --> 00:02:53.519 -for the last 15 years and - -00:02:53.519 --> 00:02:56.640 -when you think about it all chrome just - -00:02:56.640 --> 00:02:59.760 -wants to create backlinks but it sounds - -00:02:59.760 --> 00:03:01.360 -something very simple but the problem is - -00:03:01.360 --> 00:03:02.239 -that we need - -00:03:02.239 --> 00:03:05.519 -to play nicely with all of those - -00:03:05.519 --> 00:03:06.400 -intricate - -00:03:06.400 --> 00:03:09.360 -pieces and the fact is it takes quite a - -00:03:09.360 --> 00:03:10.879 -lot of expertise to be able to do so - -00:03:10.879 --> 00:03:11.440 -because - -00:03:11.440 --> 00:03:14.400 -if right now we are in the brain of all - -00:03:14.400 --> 00:03:15.200 -grow - -00:03:15.200 --> 00:03:18.959 -but if I show you the brain of org mode - -00:03:18.959 --> 00:03:21.599 -so this is the brain of org mode and it - -00:03:21.599 --> 00:03:23.280 -looks very simple like this because I - -00:03:23.280 --> 00:03:25.519 -haven't entered the less folder - -00:03:25.519 --> 00:03:28.000 -but I'm just going to enter it I'm going - -00:03:28.000 --> 00:03:29.120 -to - -00:03:29.120 --> 00:03:32.000 -zoom out a little bit don't worry if you - -00:03:32.000 --> 00:03:32.959 -don't see everything - -00:03:32.959 --> 00:03:35.519 -but I just want you to get a fear the - -00:03:35.519 --> 00:03:37.519 -sheer feel of magnitude - -00:03:37.519 --> 00:03:41.280 -that is um org mode so right now we are - -00:03:41.280 --> 00:03:42.640 -in a very small size what I'm gonna do - -00:03:42.640 --> 00:03:43.760 -I'm going to skip - -00:03:43.760 --> 00:03:47.519 -one page okay one two - -00:03:47.519 --> 00:03:51.040 -three we have let's just check how many - -00:03:51.040 --> 00:03:52.319 -lines we have - -00:03:52.319 --> 00:03:54.640 -okay let me just revert to a fairly - -00:03:54.640 --> 00:03:56.480 -readable side - -00:03:56.480 --> 00:03:58.560 -at the bottom you can see that we have - -00:03:58.560 --> 00:03:59.599 -oh it's not showing because it's a - -00:03:59.599 --> 00:04:00.959 -little small okay I'm just going to - -00:04:00.959 --> 00:04:03.840 -resize the window a little bit - -00:04:03.840 --> 00:04:06.959 -it's not showing up give me a second I - -00:04:06.959 --> 00:04:08.720 -can't see how many lines I have okay so - -00:04:08.720 --> 00:04:10.159 -let's do it to get away - -00:04:10.159 --> 00:04:11.840 -I'm going to go back at the beginning of - -00:04:11.840 --> 00:04:14.000 -the buffer and we're going to count - -00:04:14.000 --> 00:04:16.160 -how many lines we have so the bottom in - -00:04:16.160 --> 00:04:17.840 -a midi buffer and the mini buffer is - -00:04:17.840 --> 00:04:18.880 -this area - -00:04:18.880 --> 00:04:22.320 -we have 377 lines - -00:04:22.320 --> 00:04:25.919 -which means 377 - -00:04:25.919 --> 00:04:29.759 -libraries within org mode and mind you - -00:04:29.759 --> 00:04:31.520 -that's not counting all the modules that - -00:04:31.520 --> 00:04:32.960 -we have on the side which - -00:04:32.960 --> 00:04:36.240 -come on top of volt mode now when you - -00:04:36.240 --> 00:04:37.360 -try to think - -00:04:37.360 --> 00:04:40.639 -about something so elemental - -00:04:40.639 --> 00:04:44.400 -as links you have to think about how to - -00:04:44.400 --> 00:04:45.520 -play well - -00:04:45.520 --> 00:04:48.560 -with every single one of these modules - -00:04:48.560 --> 00:04:50.000 -now obviously not - -00:04:50.000 --> 00:04:53.759 -the 370 370. sometimes you know - -00:04:53.759 --> 00:04:56.080 -one module it's not going to do anything - -00:04:56.080 --> 00:04:57.680 -like I'm not sure op car could be doing - -00:04:57.680 --> 00:04:58.639 -anything with it - -00:04:58.639 --> 00:05:00.080 -but it's something that we have to keep - -00:05:00.080 --> 00:05:03.039 -in mind and so - -00:05:03.039 --> 00:05:04.720 -really early on when we started - -00:05:04.720 --> 00:05:07.520 -developing all grown with jethro kwan my - -00:05:07.520 --> 00:05:10.080 -co-maintainer you know we had this idea - -00:05:10.080 --> 00:05:10.639 -that - -00:05:10.639 --> 00:05:13.520 -we wanted to develop something that was - -00:05:13.520 --> 00:05:14.639 -optimized - -00:05:14.639 --> 00:05:18.240 -something that would you know scale very - -00:05:18.240 --> 00:05:20.160 -nicely whether or not you had - -00:05:20.160 --> 00:05:21.600 -you know something that would work as - -00:05:21.600 --> 00:05:24.560 -fast if you had 10 files - -00:05:24.560 --> 00:05:27.680 -or if you had 100 files or if you had - -00:05:27.680 --> 00:05:30.880 -10 000 files and maybe more so the - -00:05:30.880 --> 00:05:32.080 -problem when you do this - -00:05:32.080 --> 00:05:34.400 -and I'm doing some callbacks to the talk - -00:05:34.400 --> 00:05:36.320 -I gave you earlier today about - -00:05:36.320 --> 00:05:41.280 -few small few big files this is many - -00:05:41.280 --> 00:05:44.800 -I got confused few big files versus many - -00:05:44.800 --> 00:05:45.919 -small files - -00:05:45.919 --> 00:05:49.280 -the problem with this is that we need to - -00:05:49.280 --> 00:05:51.600 -think about optimization from the get go - -00:05:51.600 --> 00:05:53.680 -and so one of the decision we took when - -00:05:53.680 --> 00:05:54.800 -we got started - -00:05:54.800 --> 00:05:59.199 -with orgrum is that if I go in my - -00:05:59.199 --> 00:06:02.479 -test repository so that's the one in - -00:06:02.479 --> 00:06:04.240 -which we were right before - -00:06:04.240 --> 00:06:08.000 -we have a file which is called orgrumdb - -00:06:08.000 --> 00:06:11.600 -now if I open it it's not it's a - -00:06:11.600 --> 00:06:14.160 -little garbage because uh it's a binary - -00:06:14.160 --> 00:06:15.120 -but what we have - -00:06:15.120 --> 00:06:18.560 -is a database with which we communicate - -00:06:18.560 --> 00:06:21.919 -via sorry it's an sql database - -00:06:21.919 --> 00:06:25.120 -and what this allows us to do - -00:06:25.120 --> 00:06:28.479 -is we store all the information we need - -00:06:28.479 --> 00:06:31.919 -inside this sql database which allows us - -00:06:31.919 --> 00:06:34.720 -to speed up a lot of the operations that - -00:06:34.720 --> 00:06:35.360 -are - -00:06:35.360 --> 00:06:37.840 -necessary for the functioning of our - -00:06:37.840 --> 00:06:38.479 -ground - -00:06:38.479 --> 00:06:40.240 -so for instance if I go back to the - -00:06:40.240 --> 00:06:41.759 -index file that I had before - -00:06:41.759 --> 00:06:43.440 -let's just go back to who actually this - -00:06:43.440 --> 00:06:45.680 -way you'll see a little more on the side - -00:06:45.680 --> 00:06:47.919 -so you see that on the side we have - -00:06:47.919 --> 00:06:48.720 -whoops - -00:06:48.720 --> 00:06:50.319 -two links I'm not going to click on them - -00:06:50.319 --> 00:06:51.759 -otherwise I'm going to open them but we - -00:06:51.759 --> 00:06:53.199 -have two links - -00:06:53.199 --> 00:06:56.319 -now there are many implementations of - -00:06:56.319 --> 00:06:58.240 -the zettol casten method inside - -00:06:58.240 --> 00:07:00.800 -Emacs and inside and with old mode but - -00:07:00.800 --> 00:07:02.400 -what we've decided to do - -00:07:02.400 --> 00:07:04.639 -is that every time you have a link so if - -00:07:04.639 --> 00:07:05.520 -we go to - -00:07:05.520 --> 00:07:08.479 -the index again here at point we have - -00:07:08.479 --> 00:07:09.120 -the link - -00:07:09.120 --> 00:07:12.400 -foo every time we create a link we - -00:07:12.400 --> 00:07:14.160 -update our database - -00:07:14.160 --> 00:07:16.800 -to say okay so we have a link in the - -00:07:16.800 --> 00:07:17.919 -file - -00:07:17.919 --> 00:07:21.080 -index which is leading to the file - -00:07:21.080 --> 00:07:24.319 -fu.org and it is situated - -00:07:24.319 --> 00:07:27.840 -under the heading a heading and - -00:07:27.840 --> 00:07:29.840 -if you check the site buffer you see - -00:07:29.840 --> 00:07:31.440 -that all this all these information - -00:07:31.440 --> 00:07:33.120 -which I just highlighted to you - -00:07:33.120 --> 00:07:42.639 -are present right here - -00:07:42.639 --> 00:07:45.599 -oh well sorry I forgot this thank you - -00:07:45.599 --> 00:07:46.400 -okay - -00:07:46.400 --> 00:07:50.879 -so let's see log okay I'm going to split - -00:07:50.879 --> 00:07:53.039 -actually I'm going to split like this - -00:07:53.039 --> 00:07:54.960 -I'm going to go back there - -00:07:54.960 --> 00:07:56.960 -the problem is that I can't show my - -00:07:56.960 --> 00:07:58.720 -keystrokes at the same time as a machine - -00:07:58.720 --> 00:08:02.080 -I'm showing the site buffer so I'll - -00:08:02.080 --> 00:08:03.599 -keep it right now for your own - -00:08:03.599 --> 00:08:05.199 -discretion anyway getting back to the - -00:08:05.199 --> 00:08:07.039 -talk - -00:08:07.039 --> 00:08:10.160 -so the thing is we have this - -00:08:10.160 --> 00:08:12.720 -sql database and the goal is to keep it - -00:08:12.720 --> 00:08:13.520 -optimized - -00:08:13.520 --> 00:08:16.400 -now why is it better optimized than just - -00:08:16.400 --> 00:08:17.039 -using - -00:08:17.039 --> 00:08:20.960 -orgrom sorry just using default org mode - -00:08:20.960 --> 00:08:23.520 -so in my talk about many big files - -00:08:23.520 --> 00:08:24.080 -versus - -00:08:24.080 --> 00:08:26.879 -a few I keep getting you know you got - -00:08:26.879 --> 00:08:28.080 -what I was saying I'm not going to - -00:08:28.080 --> 00:08:29.120 -repeat it - -00:08:29.120 --> 00:08:32.240 -by the way it is uh 10 to 10. - -00:08:32.240 --> 00:08:35.200 -I'm starting really to be tired now so - -00:08:35.200 --> 00:08:36.399 -uh moving on to - -00:08:36.399 --> 00:08:39.279 -um what did I want to show you so it was - -00:08:39.279 --> 00:08:40.800 -almost yes all the elements - -00:08:40.800 --> 00:08:44.959 -so what I'm going to do I'm going to - -00:08:44.959 --> 00:08:47.200 -see I believe it's org element pass - -00:08:47.200 --> 00:08:48.399 -buffer - -00:08:48.399 --> 00:08:51.040 -so I was telling you about all elements - -00:08:51.040 --> 00:08:51.920 -before - -00:08:51.920 --> 00:08:53.600 -and the main command sorry the main - -00:08:53.600 --> 00:08:55.760 -function that is used by org element - -00:08:55.760 --> 00:08:58.560 -is pass buffer what it does and you can - -00:08:58.560 --> 00:08:59.760 -see the dock string is that it - -00:08:59.760 --> 00:09:01.040 -recursively passed - -00:09:01.040 --> 00:09:03.279 -the buffer and return structure - -00:09:03.279 --> 00:09:04.959 -structure being all the information that - -00:09:04.959 --> 00:09:06.320 -we have in this buffer - -00:09:06.320 --> 00:09:07.680 -so just to show you a little more we're - -00:09:07.680 --> 00:09:09.600 -going to move into a scratch buffer - -00:09:09.600 --> 00:09:10.880 -and what we're going to do is that we're - -00:09:10.880 --> 00:09:12.800 -going to write this command - -00:09:12.800 --> 00:09:16.320 -pass buffer and we're going to check the - -00:09:16.320 --> 00:09:17.760 -output of this command - -00:09:17.760 --> 00:09:19.600 -oh sorry not this one we're going to go - -00:09:19.600 --> 00:09:22.000 -in the index so the index file you have - -00:09:22.000 --> 00:09:23.680 -a title you have a heading you have a - -00:09:23.680 --> 00:09:25.120 -link etc etc - -00:09:25.120 --> 00:09:26.880 -so what I'm going to do I'm going to - -00:09:26.880 --> 00:09:28.560 -evaluate this text - -00:09:28.560 --> 00:09:30.800 -and now at the bottom in the midi buffer - -00:09:30.800 --> 00:09:32.560 -in the mini buffer sorry - -00:09:32.560 --> 00:09:36.160 -you see an ast an abstract - -00:09:36.160 --> 00:09:37.600 -obviously don't remember what the s - -00:09:37.600 --> 00:09:39.839 -stands for semantic - -00:09:39.839 --> 00:09:42.720 -huh interesting anyway a representation - -00:09:42.720 --> 00:09:43.519 -of the data - -00:09:43.519 --> 00:09:45.279 -in a way that is exploitable by a - -00:09:45.279 --> 00:09:47.600 -machine now what I'm going to do - -00:09:47.600 --> 00:09:49.839 -syntax thank you so what I'm going to do - -00:09:49.839 --> 00:09:52.000 -I'm going to paste it inside the buffer - -00:09:52.000 --> 00:09:54.480 -in a way that is humanly readable and - -00:09:54.480 --> 00:09:56.399 -you can see that we have plenty of - -00:09:56.399 --> 00:09:58.800 -information we have a section which - -00:09:58.800 --> 00:10:00.560 -starts at the char - -00:10:00.560 --> 00:10:05.040 -1 which ends at the character 45 - -00:10:05.040 --> 00:10:07.040 -we have the content so he makes scratch - -00:10:07.040 --> 00:10:08.240 -oh actually no - -00:10:08.240 --> 00:10:10.240 -never mind I did something wrong I run - -00:10:10.240 --> 00:10:11.279 -it in the wrong buffer - -00:10:11.279 --> 00:10:13.040 -so actually what I'm going to do we're - -00:10:13.040 --> 00:10:14.399 -going to run this command - -00:10:14.399 --> 00:10:17.519 -with the selected window next - -00:10:17.519 --> 00:10:21.120 -window okay that's a bit of live - -00:10:21.120 --> 00:10:23.760 -elise writing for you right now okay so - -00:10:23.760 --> 00:10:24.640 -now if I - -00:10:24.640 --> 00:10:26.240 -evaluate this and paste the content of - -00:10:26.240 --> 00:10:28.480 -the buffer - -00:10:28.480 --> 00:10:31.600 -it is doing its bidding so now what we - -00:10:31.600 --> 00:10:32.399 -have - -00:10:32.399 --> 00:10:34.959 -we have a section we have the keyword - -00:10:34.959 --> 00:10:36.720 -title which you see right here you have - -00:10:36.720 --> 00:10:38.160 -the value - -00:10:38.160 --> 00:10:39.920 -if we scroll down a little bit we have a - -00:10:39.920 --> 00:10:41.360 -heading which is right here we have the - -00:10:41.360 --> 00:10:42.480 -contents - -00:10:42.480 --> 00:10:44.800 -which should be yes the content is not - -00:10:44.800 --> 00:10:46.320 -listed exactly here but you have a - -00:10:46.320 --> 00:10:48.079 -paragraph which is this - -00:10:48.079 --> 00:10:50.640 -and then you have a link etc etc it is - -00:10:50.640 --> 00:10:51.200 -all - -00:10:51.200 --> 00:10:53.839 -uh parenthesis if you're not used to - -00:10:53.839 --> 00:10:54.640 -e-list - -00:10:54.640 --> 00:10:56.320 -like right now I've selected only the - -00:10:56.320 --> 00:10:58.640 -content of the parenthesis link - -00:10:58.640 --> 00:11:00.399 -I can move like this etcetera etcetera - -00:11:00.399 --> 00:11:01.680 -I'm not it's not a needle - -00:11:01.680 --> 00:11:03.760 -lessons that I'm doing right now but - -00:11:03.760 --> 00:11:05.279 -basically - -00:11:05.279 --> 00:11:08.399 -if we were to use the default tooling of - -00:11:08.399 --> 00:11:09.120 -orgrom - -00:11:09.120 --> 00:11:10.880 -org mode sorry I keep getting too - -00:11:10.880 --> 00:11:12.480 -confused sorry for that - -00:11:12.480 --> 00:11:14.240 -uh it would be extremely slow to do what - -00:11:14.240 --> 00:11:16.399 -we're doing some people - -00:11:16.399 --> 00:11:19.760 -are doing so some implementations of the - -00:11:19.760 --> 00:11:22.240 -zettelkassen method inside Emacs have - -00:11:22.240 --> 00:11:23.040 -opted - -00:11:23.040 --> 00:11:26.480 -for this method but the problem is that - -00:11:26.480 --> 00:11:27.360 -we think - -00:11:27.360 --> 00:11:30.160 -that it scales poorly now some other - -00:11:30.160 --> 00:11:30.560 -people - -00:11:30.560 --> 00:11:33.920 -have decided to not do with a database - -00:11:33.920 --> 00:11:35.600 -and what they do is that they use a tool - -00:11:35.600 --> 00:11:37.200 -which is called rip grep - -00:11:37.200 --> 00:11:38.800 -you might know grep which is a tool that - -00:11:38.800 --> 00:11:41.279 -allows you to search - -00:11:41.279 --> 00:11:43.440 -a file the content of a file for a line - -00:11:43.440 --> 00:11:46.560 -so for instance if we open v term here - -00:11:46.560 --> 00:11:49.680 -uh let's see so I've opened the term I - -00:11:49.680 --> 00:11:51.839 -am in this repository what I'm going to - -00:11:51.839 --> 00:11:54.399 -do is that I'm going to - -00:11:54.399 --> 00:11:58.000 -load the content of the file uh - -00:11:58.000 --> 00:12:00.480 -how am I going to do this oh um I need - -00:12:00.480 --> 00:12:02.480 -to move to bash - -00:12:02.480 --> 00:12:06.160 -let's do crap - -00:12:06.160 --> 00:12:08.000 -for the line which links do we did we - -00:12:08.000 --> 00:12:09.519 -have grep foo - -00:12:09.519 --> 00:12:11.600 -inside the file is it three I can - -00:12:11.600 --> 00:12:13.760 -remember okay let's do this - -00:12:13.760 --> 00:12:18.079 -am I working no - -00:12:18.079 --> 00:12:21.279 -let's go for four why is it eight - -00:12:21.279 --> 00:12:22.800 -ah damn it oh you know what I'm just - -00:12:22.800 --> 00:12:24.320 -going to copy the name - -00:12:24.320 --> 00:12:28.240 -up there we go no - -00:12:28.240 --> 00:12:33.680 -ah problem with live presentation always - -00:12:33.680 --> 00:12:34.800 -you know what I'm struggling so I'm - -00:12:34.800 --> 00:12:36.720 -going to drop this point anyway - -00:12:36.720 --> 00:12:38.560 -so grep is a simple tool that allows you - -00:12:38.560 --> 00:12:40.000 -to search the content of a file but - -00:12:40.000 --> 00:12:42.480 -rig grep is a solution that is written - -00:12:42.480 --> 00:12:44.160 -in rust and which is supposed to be - -00:12:44.160 --> 00:12:45.920 -well not supposed which is far more - -00:12:45.920 --> 00:12:48.880 -capable now - -00:12:48.880 --> 00:12:50.639 -I'd like to talk to you about the future - -00:12:50.639 --> 00:12:52.320 -of orgrim right now I've told you about - -00:12:52.320 --> 00:12:54.720 -the general concept which is about using - -00:12:54.720 --> 00:12:58.399 -uh this sql database and about - -00:12:58.399 --> 00:13:01.519 -playing nicely with old mode but - -00:13:01.519 --> 00:13:03.279 -we think that there's something great - -00:13:03.279 --> 00:13:05.200 -that we can do about orgrim - -00:13:05.200 --> 00:13:08.320 -now I've been talking with the a lot of - -00:13:08.320 --> 00:13:10.320 -people who are behind org mode and you - -00:13:10.320 --> 00:13:10.880 -know - -00:13:10.880 --> 00:13:14.000 -they've told us do you think that - -00:13:14.000 --> 00:13:16.880 -orgrom could have something to bring to - -00:13:16.880 --> 00:13:18.320 -old mode let's say - -00:13:18.320 --> 00:13:20.160 -backlinks is there something that we - -00:13:20.160 --> 00:13:21.600 -could be doing to - -00:13:21.600 --> 00:13:25.600 -import backlinks into old mode and - -00:13:25.600 --> 00:13:27.200 -we thought about it with jethro and the - -00:13:27.200 --> 00:13:29.200 -problem is uh - -00:13:29.200 --> 00:13:30.800 -we've always tried to have an - -00:13:30.800 --> 00:13:32.720 -experimental ground a very - -00:13:32.720 --> 00:13:35.360 -uh can a very isolated portion of your - -00:13:35.360 --> 00:13:36.320 -system - -00:13:36.320 --> 00:13:37.920 -where we could track backlinks and - -00:13:37.920 --> 00:13:40.320 -that's why we use um - -00:13:40.320 --> 00:13:42.320 -a slipbox directory so that we only - -00:13:42.320 --> 00:13:44.880 -track backlinks in one specific place - -00:13:44.880 --> 00:13:47.040 -but now because there seems to be so - -00:13:47.040 --> 00:13:48.639 -much interest about the method and we - -00:13:48.639 --> 00:13:50.079 -have so much backing - -00:13:50.079 --> 00:13:52.480 -on uh you know on github we have like - -00:13:52.480 --> 00:13:53.120 -200 - -00:13:53.120 --> 00:13:56.399 -2 600 stars which is mind-boggling to us - -00:13:56.399 --> 00:13:59.760 -because we have so much success but - -00:13:59.760 --> 00:14:02.399 -we have plenty of ideas about the future - -00:14:02.399 --> 00:14:03.360 -one of the key - -00:14:03.360 --> 00:14:06.000 -parts of development being the writing - -00:14:06.000 --> 00:14:08.480 -of an external parser for orgrim - -00:14:08.480 --> 00:14:09.680 -so I've been telling you about org - -00:14:09.680 --> 00:14:11.839 -element org elements runs - -00:14:11.839 --> 00:14:15.279 -inside Emacs but what if - -00:14:15.279 --> 00:14:19.519 -we wrote a background process - -00:14:19.519 --> 00:14:23.600 -that could read a file an augment file - -00:14:23.600 --> 00:14:25.760 -extract the same type of data that you - -00:14:25.760 --> 00:14:27.440 -see on your screen right now - -00:14:27.440 --> 00:14:30.240 -so that we could use to update a - -00:14:30.240 --> 00:14:30.959 -database - -00:14:30.959 --> 00:14:33.279 -so that we could use to compute the - -00:14:33.279 --> 00:14:34.959 -links so that we could use it - -00:14:34.959 --> 00:14:37.360 -to show you know orgrim server all the - -00:14:37.360 --> 00:14:39.519 -connections between your nodes - -00:14:39.519 --> 00:14:41.360 -now there is a path of improvement here - -00:14:41.360 --> 00:14:44.320 -that is extremely important to us - -00:14:44.320 --> 00:14:47.360 -but you know that's the technical aspect - -00:14:47.360 --> 00:14:48.639 -and I'm out of time I'm just going to - -00:14:48.639 --> 00:14:50.079 -take one more minute to finish on this - -00:14:50.079 --> 00:14:51.360 -point - -00:14:51.360 --> 00:14:54.560 -but we believe - -00:14:54.560 --> 00:14:57.680 -that orgrim has the potential to be a - -00:14:57.680 --> 00:14:58.399 -think tank - -00:14:58.399 --> 00:15:00.639 -in a way for org mode and the way we - -00:15:00.639 --> 00:15:01.920 -think about - -00:15:01.920 --> 00:15:04.079 -note-taking in general I've stressed a - -00:15:04.079 --> 00:15:06.079 -great deal in my first presentation - -00:15:06.079 --> 00:15:10.240 -sorry the one I did before neura that - -00:15:10.240 --> 00:15:12.480 -all chrome is really great as a way to - -00:15:12.480 --> 00:15:14.639 -think organically about knowledge - -00:15:14.639 --> 00:15:17.600 -and honestly we kind of want to put the - -00:15:17.600 --> 00:15:19.279 -theory into practice with orgrim - -00:15:19.279 --> 00:15:22.079 -we are holding something which has the - -00:15:22.079 --> 00:15:23.440 -potential to be - -00:15:23.440 --> 00:15:25.120 -a great factor of innovation for the - -00:15:25.120 --> 00:15:27.279 -future whether it be or org mode - -00:15:27.279 --> 00:15:29.600 -or even for software in general you know - -00:15:29.600 --> 00:15:31.440 -the way to think about - -00:15:31.440 --> 00:15:34.880 -build nodes of knowledge in a way - -00:15:34.880 --> 00:15:37.440 -and the way to represent all those ids - -00:15:37.440 --> 00:15:38.240 -with the graph - -00:15:38.240 --> 00:15:40.560 -the way to basically have a note-taking - -00:15:40.560 --> 00:15:41.600 -system that - -00:15:41.600 --> 00:15:43.360 -corresponds to the research that - -00:15:43.360 --> 00:15:45.839 -corresponds to the way you think - -00:15:45.839 --> 00:15:49.120 -so yeah I believe we are - -00:15:49.120 --> 00:15:51.839 -really excited about this and if you - -00:15:51.839 --> 00:15:53.519 -want to keep track of the development of - -00:15:53.519 --> 00:15:55.360 -all chrome - -00:15:55.360 --> 00:15:57.600 -I on my youtube channel which is already - -00:15:57.600 --> 00:15:59.279 -linked a little earlier - -00:15:59.279 --> 00:16:02.639 -inside this present inside the pad sorry - -00:16:02.639 --> 00:16:04.240 -I do have a youtube channel where I try - -00:16:04.240 --> 00:16:06.079 -to present novelties - -00:16:06.079 --> 00:16:09.519 -or the new stuff inside um orgrim - -00:16:09.519 --> 00:16:11.519 -but I also be recording videos about the - -00:16:11.519 --> 00:16:13.360 -technical aspects about the direction - -00:16:13.360 --> 00:16:15.519 -that we're taking with orgrim - -00:16:15.519 --> 00:16:18.000 -and if you want to talk with us we are - -00:16:18.000 --> 00:16:18.560 -always - -00:16:18.560 --> 00:16:22.160 -available either on isc channel orgrom - -00:16:22.160 --> 00:16:23.680 -I believe there's a dash between org and - -00:16:23.680 --> 00:16:25.279 -rome but also - -00:16:25.279 --> 00:16:27.279 -on the discourse and I'll be putting all - -00:16:27.279 --> 00:16:29.440 -the links inside the conversation - -00:16:29.440 --> 00:16:31.199 -and that's me done so thank you for - -00:16:31.199 --> 00:16:32.880 -listening and now I'll be taking - -00:16:32.880 --> 00:16:34.560 -three minutes of questions so as to be - -00:16:34.560 --> 00:16:37.360 -right on time - -00:16:37.360 --> 00:16:39.920 -mini thanks for your awesome talk leo - -00:16:39.920 --> 00:16:41.120 -thank you - -00:16:41.120 --> 00:16:43.040 -so I'm just refreshing the page and I'm - -00:16:43.040 --> 00:16:44.959 -going to scroll down to my - -00:16:44.959 --> 00:16:49.600 -talk if I can find the right section - -00:16:49.600 --> 00:16:53.120 -let me just scroll a little bit - -00:16:53.120 --> 00:16:55.600 -uh reproducible Emacs no I think it's - -00:16:55.600 --> 00:16:57.120 -slower - -00:16:57.120 --> 00:16:59.279 -god we have so many questions so at the - -00:16:59.279 --> 00:17:00.639 -same time I'm pissed because I can't - -00:17:00.639 --> 00:17:01.120 -find it - -00:17:01.120 --> 00:17:02.639 -but I'm really really impressed by the - -00:17:02.639 --> 00:17:05.360 -number of questions that we had oh yeah - -00:17:05.360 --> 00:17:07.760 -um which is about I think about line 600 - -00:17:07.760 --> 00:17:08.260 -or so - -00:17:08.260 --> 00:17:09.919 -[Music] - -00:17:09.919 --> 00:17:13.199 -yes got it splendid - -00:17:13.199 --> 00:17:16.400 -so um the questions so why not run a - -00:17:16.400 --> 00:17:18.160 -background Emacs for passing instead of - -00:17:18.160 --> 00:17:19.919 -implementing a new parser - -00:17:19.919 --> 00:17:22.559 -so I believe we've had this question uh - -00:17:22.559 --> 00:17:24.480 -I was giving a similar talk - -00:17:24.480 --> 00:17:27.600 -earlier this week and this week - -00:17:27.600 --> 00:17:31.679 -I'm not french this week sorry and - -00:17:31.679 --> 00:17:33.280 -someone asked me this question and the - -00:17:33.280 --> 00:17:35.679 -thing is running a background Emacs - -00:17:35.679 --> 00:17:38.320 -process you know it sounds great - -00:17:38.320 --> 00:17:40.400 -but it's also very limited because all - -00:17:40.400 --> 00:17:41.760 -the problems we have - -00:17:41.760 --> 00:17:45.520 -about concurrency about threads in Emacs - -00:17:45.520 --> 00:17:48.160 -well yes we can forward all our calls to - -00:17:48.160 --> 00:17:49.200 -background Emacs - -00:17:49.200 --> 00:17:51.760 -just like uh you know when you export a - -00:17:51.760 --> 00:17:52.240 -file - -00:17:52.240 --> 00:17:56.400 -with uh um sorry - -00:17:56.400 --> 00:17:57.840 -I mean could you mute microphone when - -00:17:57.840 --> 00:17:58.799 -you're speaking it's a little hard for - -00:17:58.799 --> 00:18:01.520 -me to concentrate - -00:18:01.520 --> 00:18:03.600 -that's fine don't worry you are now uh - -00:18:03.600 --> 00:18:04.640 -so um - -00:18:04.640 --> 00:18:06.960 -dammit where was I I'm sorry the - -00:18:06.960 --> 00:18:07.679 -question yes - -00:18:07.679 --> 00:18:09.280 -so basically forwarding all the - -00:18:09.280 --> 00:18:11.840 -questions uh sorry all our queries to uh - -00:18:11.840 --> 00:18:13.039 -background Emacs - -00:18:13.039 --> 00:18:16.000 -that is what uh org export is doing like - -00:18:16.000 --> 00:18:17.960 -you have the ability to - -00:18:17.960 --> 00:18:20.799 -asynchronously export latex documents - -00:18:20.799 --> 00:18:22.080 -odt documents from - -00:18:22.080 --> 00:18:24.480 -org mode and it uses a very minimal - -00:18:24.480 --> 00:18:26.000 -version of Emacs to do that but the - -00:18:26.000 --> 00:18:28.240 -problem is that we think that it's not - -00:18:28.240 --> 00:18:30.320 -going to scale as well as a true - -00:18:30.320 --> 00:18:33.039 -genuine background process and since we - -00:18:33.039 --> 00:18:34.480 -have been talking a lot - -00:18:34.480 --> 00:18:36.000 -as far as the old mode development is - -00:18:36.000 --> 00:18:38.160 -concerned about - -00:18:38.160 --> 00:18:40.640 -writing a proper parser writing a proper - -00:18:40.640 --> 00:18:41.760 -documentation - -00:18:41.760 --> 00:18:43.440 -for the passing of old mode file and - -00:18:43.440 --> 00:18:46.000 -writing a proper document standard - -00:18:46.000 --> 00:18:48.400 -that says okay this is how the old mode - -00:18:48.400 --> 00:18:50.000 -format works you know to - -00:18:50.000 --> 00:18:52.000 -basically have a way to not fall into - -00:18:52.000 --> 00:18:55.120 -the traps of markdown which has many - -00:18:55.120 --> 00:18:56.559 -many standards - -00:18:56.559 --> 00:18:58.480 -we need to think about this and we - -00:18:58.480 --> 00:19:00.000 -believe that all grown has - -00:19:00.000 --> 00:19:01.360 -the ability to think about these - -00:19:01.360 --> 00:19:03.120 -questions and as a - -00:19:03.120 --> 00:19:04.640 -as a person I'm also really interested - -00:19:04.640 --> 00:19:06.400 -about this so - -00:19:06.400 --> 00:19:07.840 -I can take the question I mean so don't - -00:19:07.840 --> 00:19:10.160 -worry about feeding them to me so how - -00:19:10.160 --> 00:19:11.760 -often does the - -00:19:11.760 --> 00:19:13.679 -db index get updated in order to contain - -00:19:13.679 --> 00:19:14.799 -changes within the - -00:19:14.799 --> 00:19:17.360 -files so we have two ways either we - -00:19:17.360 --> 00:19:19.440 -update as soon as you save a file - -00:19:19.440 --> 00:19:22.160 -or we have a timer which is an idle - -00:19:22.160 --> 00:19:23.600 -timer which waits okay - -00:19:23.600 --> 00:19:25.600 -the user has not imputed inputted - -00:19:25.600 --> 00:19:26.960 -anything in the last - -00:19:26.960 --> 00:19:29.360 -five seconds so it's time to queue a - -00:19:29.360 --> 00:19:30.080 -database - -00:19:30.080 --> 00:19:33.039 -passing a rebuild of the data not a an - -00:19:33.039 --> 00:19:33.919 -incrementation - -00:19:33.919 --> 00:19:37.120 -of the database I should say so - -00:19:37.120 --> 00:19:38.799 -did you ever think of uh I believe I - -00:19:38.799 --> 00:19:40.320 -have one more one more minutes and then - -00:19:40.320 --> 00:19:42.240 -I'll hand it to the other folks - -00:19:42.240 --> 00:19:43.440 -do you ever think of opening up or - -00:19:43.440 --> 00:19:45.440 -designing the sqldb as a general all - -00:19:45.440 --> 00:19:47.200 -speed up tool outside of orgrom so that - -00:19:47.200 --> 00:19:48.160 -other libraries - -00:19:48.160 --> 00:19:49.919 -that do execute complex queries are able - -00:19:49.919 --> 00:19:51.679 -to use it well - -00:19:51.679 --> 00:19:52.960 -a lot of people have been working on - -00:19:52.960 --> 00:19:54.640 -this and I believe alpha papa has been - -00:19:54.640 --> 00:19:56.480 -thinking quite a lot about this you know - -00:19:56.480 --> 00:19:57.679 -all ql - -00:19:57.679 --> 00:20:01.120 -is the ql stands for language - -00:20:01.120 --> 00:20:03.679 -and I I can't remember now what's uh - -00:20:03.679 --> 00:20:04.720 -what's the backend - -00:20:04.720 --> 00:20:08.080 -is for all ql but the idea is relatively - -00:20:08.080 --> 00:20:10.080 -relatively the same you know it's about - -00:20:10.080 --> 00:20:13.039 -finding ways to optimize the way we - -00:20:13.039 --> 00:20:14.880 -store the data about an old mode file - -00:20:14.880 --> 00:20:16.640 -and how we retrieve it - -00:20:16.640 --> 00:20:20.400 -and sql for us seems to seem to be a - -00:20:20.400 --> 00:20:22.159 -good idea now obviously - -00:20:22.159 --> 00:20:24.240 -maybe we could do something about old - -00:20:24.240 --> 00:20:26.080 -mode but the problem is I think a - -00:20:26.080 --> 00:20:27.360 -background process - -00:20:27.360 --> 00:20:30.799 -is not necessarily um in - -00:20:30.799 --> 00:20:32.960 -the core mentality of old mode but it's - -00:20:32.960 --> 00:20:34.000 -definitely a - -00:20:34.000 --> 00:20:36.080 -something that we could suggest uh when - -00:20:36.080 --> 00:20:37.679 -we are a little more mature because well - -00:20:37.679 --> 00:20:40.960 -orgrom was started last february and so - -00:20:40.960 --> 00:20:41.679 -it's a fairly - -00:20:41.679 --> 00:20:44.480 -young project in a way so uh I see - -00:20:44.480 --> 00:20:45.840 -plenty more questions but - -00:20:45.840 --> 00:20:48.400 -I'm out of time folks so I'm not sure uh - -00:20:48.400 --> 00:20:50.559 -the other speaker is probably ready - -00:20:50.559 --> 00:20:52.559 -so what I'll do is I'll probably try to - -00:20:52.559 --> 00:20:54.000 -answer your questions when I get the - -00:20:54.000 --> 00:20:55.360 -time inside the pad - -00:20:55.360 --> 00:20:58.960 -but feel free to ping me on isc - -00:20:58.960 --> 00:21:01.039 -or on the different channels we have - -00:21:01.039 --> 00:21:02.320 -foreground and - -00:21:02.320 --> 00:21:04.000 -I answer them with you know as much - -00:21:04.000 --> 00:21:05.520 -energy as I can gather - -00:21:05.520 --> 00:21:07.600 -all right thank you so much you are now - -00:21:07.600 --> 00:21:08.880 -unmuted - -00:21:08.880 --> 00:21:11.760 -thank you again very much leo and that - -00:21:11.760 --> 00:21:13.120 -was me done for today so you'll see me - -00:21:13.120 --> 00:21:14.000 -at the end but I'm - -00:21:14.000 --> 00:21:15.840 -officially done and I am free of - -00:21:15.840 --> 00:21:17.840 -thoughts I can focus on - -00:21:17.840 --> 00:21:22.640 -sleeping probably awesome -
