+0:00:48.160,0:00:51.280 +as you can possibly get with those + +0:00:49.760,0:00:54.000 +topics and by the way + +0:00:51.280,0:00:55.760 +uh credit where credit is due the title + +0:00:54.000,0:00:57.039 +is not mine it's actually from bastian + +0:00:55.760,0:01:00.719 +gary the current old + +0:00:57.039,0:01:03.199 +maintainer and yeah i wanted to + +0:01:00.719,0:01:04.879 +talk to you a little bit today about + +0:01:03.199,0:01:07.600 +this question because + +0:01:04.879,0:01:09.040 +if you are used to going on our slash + +0:01:07.600,0:01:09.600 +emacs you know the subreddit that we + +0:01:09.040,0:01:11.840 +have + +0:01:09.600,0:01:13.200 +if you go on i can use often you know + +0:01:11.840,0:01:16.000 +it's a question that + +0:01:13.200,0:01:17.520 +you see pop-up every once in a while + +0:01:16.000,0:01:20.640 +should i be using + +0:01:17.520,0:01:24.159 +one big file or should i be using + +0:01:20.640,0:01:24.799 +a lot of tiny files and i believe you + +0:01:24.159,0:01:27.600 +know + +0:01:24.799,0:01:29.520 +we've got defenders on both sides if i + +0:01:27.600,0:01:32.479 +just show you one examples + +0:01:29.520,0:01:35.280 +so we have carl voigt okay so he's one + +0:01:32.479,0:01:37.920 +of the organizers for the conference + +0:01:35.280,0:01:40.000 +he hears the guy who probably has the + +0:01:37.920,0:01:42.000 +biggest augment files + +0:01:40.000,0:01:43.759 +right now in all the people i know and + +0:01:42.000,0:01:44.479 +god knows i know plenty of people use + +0:01:43.759,0:01:46.880 +old mode + +0:01:44.479,0:01:48.320 +but if you just look at this line i hope + +0:01:46.880,0:01:51.360 +it's not too small you just + +0:01:48.320,0:01:56.719 +make it a little larger but + +0:01:51.360,0:02:01.759 +carl basically has a file with 126 + +0:01:56.719,0:02:04.560 +000 lines and i'm just going to pause + +0:02:01.759,0:02:06.399 +and try to have you imagine how large a + +0:02:04.560,0:02:08.399 +file it actually is + +0:02:06.399,0:02:10.000 +just think about all of these lines + +0:02:08.399,0:02:12.080 +being tasked in your days + +0:02:10.000,0:02:13.200 +think about all those lines being about + +0:02:12.080,0:02:14.400 +little thoughts + +0:02:13.200,0:02:17.200 +you know that you've had throughout the + +0:02:14.400,0:02:19.680 +day or project that you were working on + +0:02:17.200,0:02:20.720 +and it's massive and you know one of the + +0:02:19.680,0:02:23.920 +problem that + +0:02:20.720,0:02:27.680 +uh calvoit actually approaches on + +0:02:23.920,0:02:30.160 +this topic is that it takes him roughly + +0:02:27.680,0:02:32.400 +20 seconds to get his old agenda going + +0:02:30.160,0:02:35.680 +which is a massive amount of time + +0:02:32.400,0:02:37.720 +i mean we have very fast computers now + +0:02:35.680,0:02:39.200 +you know ever since e-max was created in + +0:02:37.720,0:02:42.319 +1976 + +0:02:39.200,0:02:43.440 +computers i have no idea how much faster + +0:02:42.319,0:02:47.760 +they've gotten + +0:02:43.440,0:02:49.599 +and yet you know for earth 1000 lines + +0:02:47.760,0:02:51.120 +emac seems to be choking and it's + +0:02:49.599,0:02:52.720 +certainly not reasonable in a way to + +0:02:51.120,0:02:55.360 +have to wait 20 seconds + +0:02:52.720,0:02:57.040 +just for your entire file to be passed + +0:02:55.360,0:02:58.480 +so basically what i want to do + +0:02:57.040,0:03:00.879 +and by the way i forgot to do the + +0:02:58.480,0:03:02.879 +presentation but i'm leova i did this + +0:03:00.879,0:03:05.519 +before for those who were around + +0:03:02.879,0:03:06.640 +and i um help maintain a software which + +0:03:05.519,0:03:08.560 +is called orgrom + +0:03:06.640,0:03:09.840 +and that's the expertise that i have on + +0:03:08.560,0:03:11.760 +the topic + +0:03:09.840,0:03:13.599 +actually if you go online i do have a + +0:03:11.760,0:03:15.440 +github page i will make sure that you + +0:03:13.599,0:03:18.640 +have all the links available afterwards + +0:03:15.440,0:03:20.720 +but i do publish my init files + +0:03:18.640,0:03:22.319 +and you can see if you scroll at the + +0:03:20.720,0:03:23.200 +bottom i have a little demonstration + +0:03:22.319,0:03:25.519 +which shows you + +0:03:23.200,0:03:27.440 +the fancy things that i can do with my + +0:03:25.519,0:03:28.159 +old mood setup and that might be even + +0:03:27.440,0:03:30.720 +interesting + +0:03:28.159,0:03:32.319 +in lights of the talk you've just had + +0:03:30.720,0:03:34.080 +about gtd stuff because + +0:03:32.319,0:03:36.159 +the first one is about how i end all my + +0:03:34.080,0:03:39.680 +projects the second one is about + +0:03:36.159,0:03:40.000 +the flow from a task uh as i work on it + +0:03:39.680,0:03:41.519 +so + +0:03:40.000,0:03:43.120 +i won't spend too much time on this but + +0:03:41.519,0:03:45.440 +basically that's my expertise + +0:03:43.120,0:03:46.959 +i have spent eight years working with + +0:03:45.440,0:03:48.959 +working with org mode + +0:03:46.959,0:03:50.720 +three of them actually thinking about + +0:03:48.959,0:03:54.080 +writing packages + +0:03:50.720,0:03:55.680 +and the thing is if i go into a little + +0:03:54.080,0:03:57.760 +bit of details and obviously it's only a + +0:03:55.680,0:04:00.720 +lighting talk so i won't have time to + +0:03:57.760,0:04:01.840 +actually go really in depth about it but + +0:04:00.720,0:04:03.599 +there is something + +0:04:01.840,0:04:05.200 +in the ultimate libraries which is + +0:04:03.599,0:04:07.000 +called org elements + +0:04:05.200,0:04:08.319 +and you have the name right there org + +0:04:07.000,0:04:11.439 +element.el + +0:04:08.319,0:04:12.319 +dot el being for e-lisp file and as you + +0:04:11.439,0:04:14.799 +can see + +0:04:12.319,0:04:16.239 +the page it's on the work wiki so it's + +0:04:14.799,0:04:19.280 +accessible by everyone + +0:04:16.239,0:04:23.759 +but it's basically the api that + +0:04:19.280,0:04:26.400 +org mode uses to pass all mode files + +0:04:23.759,0:04:27.199 +so for those who don't know passing + +0:04:26.400,0:04:29.360 +means basically + +0:04:27.199,0:04:30.880 +checking a file checking all the content + +0:04:29.360,0:04:32.880 +of the file and extracting all the + +0:04:30.880,0:04:34.960 +information that we need from that file + +0:04:32.880,0:04:36.560 +and as you can imagine you all have + +0:04:34.960,0:04:38.240 +augmented files in your mind + +0:04:36.560,0:04:39.840 +well you know they can be fairly complex + +0:04:38.240,0:04:41.759 +you know you can have properties + +0:04:39.840,0:04:43.040 +you can have contextual information like + +0:04:41.759,0:04:45.199 +if you write a line + +0:04:43.040,0:04:46.560 +which starts at column zero which means + +0:04:45.199,0:04:48.000 +at the left + +0:04:46.560,0:04:49.680 +you know it doesn't have the same + +0:04:48.000,0:04:52.639 +meaning whether or not it is + +0:04:49.680,0:04:54.160 +before the beginning of a headline or if + +0:04:52.639,0:04:55.199 +it is after the beginning of a red line + +0:04:54.160,0:04:57.759 +you know it's going to be + +0:04:55.199,0:04:58.960 +relatively different hierarchically + +0:04:57.759,0:05:01.759 +speaking + +0:04:58.960,0:05:02.639 +and so the problem when it comes to the + +0:05:01.759,0:05:05.759 +question of + +0:05:02.639,0:05:08.560 +many files versus one big file or + +0:05:05.759,0:05:09.600 +few big files is that we always have to + +0:05:08.560,0:05:12.880 +keep in mind + +0:05:09.600,0:05:15.680 +what org elements want you to do + +0:05:12.880,0:05:17.440 +and the thing is there are plenty of + +0:05:15.680,0:05:18.400 +problems when it comes to passing file + +0:05:17.440,0:05:21.360 +the first one + +0:05:18.400,0:05:22.160 +being obviously that emacs is a single + +0:05:21.360,0:05:24.880 +thread + +0:05:22.160,0:05:26.400 +process or has some threading + +0:05:24.880,0:05:28.639 +capabilities we're not going to go into + +0:05:26.400,0:05:32.400 +the details right now that's not my goal + +0:05:28.639,0:05:35.919 +but it makes it incredibly hard to + +0:05:32.400,0:05:39.280 +parallelize uh passing processes as + +0:05:35.919,0:05:42.320 +we currently with the current technology + +0:05:39.280,0:05:44.080 +and so you'd have to imagine that if you + +0:05:42.320,0:05:46.479 +have a very large files if you go back + +0:05:44.080,0:05:49.199 +to the example of carl voice from before + +0:05:46.479,0:05:50.000 +100 000 lines that means that you have + +0:05:49.199,0:05:52.320 +to scan + +0:05:50.000,0:05:53.759 +through every single line basically + +0:05:52.320,0:05:56.080 +because sometimes let's just say that + +0:05:53.759,0:05:59.440 +you have a property drawer for instance + +0:05:56.080,0:06:03.520 +which tells you oh okay uh this tree + +0:05:59.440,0:06:05.120 +has the tag foo so the problem is there + +0:06:03.520,0:06:08.720 +are multiple ways for you + +0:06:05.120,0:06:11.840 +to define a tag okay so you can use the + +0:06:08.720,0:06:14.000 +usual way which is about wrapping in + +0:06:11.840,0:06:16.160 +columns the tag at the end of a heading + +0:06:14.000,0:06:17.360 +so for instance if i i'm not going to + +0:06:16.160,0:06:18.240 +switch to emac that's going to waste too + +0:06:17.360,0:06:21.039 +much time + +0:06:18.240,0:06:21.520 +but that's one way to say your time but + +0:06:21.039,0:06:23.520 +say + +0:06:21.520,0:06:25.360 +you have tag inheritance which means + +0:06:23.520,0:06:28.160 +that when you have a parent with a tag + +0:06:25.360,0:06:29.520 +you also want the child to inherit the + +0:06:28.160,0:06:32.400 +tag so if you have + +0:06:29.520,0:06:33.680 +first heading with the typhoo you have + +0:06:32.400,0:06:37.520 +the first subheading + +0:06:33.680,0:06:39.680 +and the tag foo is implied now imagine + +0:06:37.520,0:06:41.039 +having to do that with a file that is + +0:06:39.680,0:06:44.160 +completely nested + +0:06:41.039,0:06:47.280 +a file that has maybe 9 10 + +0:06:44.160,0:06:49.039 +11 levels of depth to it + +0:06:47.280,0:06:51.039 +it's mind-bogglingly complicated for the + +0:06:49.039,0:06:52.639 +software to do that knowing that i've + +0:06:51.039,0:06:55.919 +told you about tags + +0:06:52.639,0:06:58.639 +but any property can be inheritable + +0:06:55.919,0:07:00.240 +anything like priorities even though why + +0:06:58.639,0:07:03.759 +would you do this + +0:07:00.240,0:07:05.599 +you can have groups you can all this and + +0:07:03.759,0:07:07.199 +as someone who went through the trouble + +0:07:05.599,0:07:08.560 +of optimizing his old agenda so + +0:07:07.199,0:07:11.280 +basically if we go back to the + +0:07:08.560,0:07:12.160 +gifts gifs oh god we've already had this + +0:07:11.280,0:07:14.479 +discussion + +0:07:12.160,0:07:16.400 +between the git and magit and now i've + +0:07:14.479,0:07:18.080 +started jeff and gif and i only have one + +0:07:16.400,0:07:19.599 +more minute left to do so so let's just + +0:07:18.080,0:07:23.599 +say i'm going to say gif + +0:07:19.599,0:07:26.880 +just to spice people so if you go on + +0:07:23.599,0:07:29.120 +the way i organize my agenda what i did + +0:07:26.880,0:07:30.960 +in order to keep my agenda build time + +0:07:29.120,0:07:33.440 +under two seconds + +0:07:30.960,0:07:35.520 +is that i've rewritten a whole lot of + +0:07:33.440,0:07:36.560 +codes to be able to pass my organ gender + +0:07:35.520,0:07:40.080 +files + +0:07:36.560,0:07:41.360 +so the thing is i'm going to be talking + +0:07:40.080,0:07:43.440 +more about this later + +0:07:41.360,0:07:44.479 +i only have let's say one minutes to + +0:07:43.440,0:07:47.440 +conclude + +0:07:44.479,0:07:48.479 +so as you've gathered i'm not going to + +0:07:47.440,0:07:51.039 +be giving you the answer + +0:07:48.479,0:07:53.440 +right now i'm going to be talking about + +0:07:51.039,0:07:55.680 +orgrum a little later which is about + +0:07:53.440,0:07:57.759 +following the principle of having many + +0:07:55.680,0:08:01.120 +small files + +0:07:57.759,0:08:02.960 +but as someone who has been using + +0:08:01.120,0:08:04.879 +one large file to manage my life you + +0:08:02.960,0:08:08.319 +know i'm sitting on the fence + +0:08:04.879,0:08:10.560 +i do not know which one is the best + +0:08:08.319,0:08:12.240 +but i hope that my presentation has + +0:08:10.560,0:08:15.199 +given you a little id + +0:08:12.240,0:08:15.520 +of what goes on behind the principles + +0:08:15.199,0:08:16.560 +and + +0:08:15.520,0:08:18.560 +you also need to think about the + +0:08:16.560,0:08:19.120 +philosophy behind the organization of + +0:08:18.560,0:08:21.039 +your notes + +0:08:19.120,0:08:23.280 +but i hope to be approaching this topic + +0:08:21.039,0:08:25.360 +with you in about + +0:08:23.280,0:08:27.520 +two hours or so maybe one hour actually + +0:08:25.360,0:08:28.960 +so i'm actually finished i've decided to + +0:08:27.520,0:08:31.520 +leave you two minutes of questions + +0:08:28.960,0:08:32.880 +so uh if someone could feed me the + +0:08:31.520,0:08:34.399 +question that might be best + +0:08:32.880,0:08:36.240 +because i don't want oh actually i can + +0:08:34.399,0:08:39.919 +just open the year + +0:08:36.240,0:08:40.800 +i can just open it give me a second okay + +0:08:39.919,0:08:43.039 +ah + +0:08:40.800,0:08:43.839 +just loading up huh i might stop showing + +0:08:43.039,0:08:46.959 +my screen + +0:08:43.839,0:08:47.519 +that might make it easier so i mean if + +0:08:46.959,0:08:49.360 +you can make + +0:08:47.519,0:08:52.000 +myself big now on the screen that would + +0:08:49.360,0:08:55.839 +be splendid yeah sure + +0:08:52.000,0:08:58.720 +thank you so uh where are we + +0:08:55.839,0:09:00.160 +question 12. okay so what's better one + +0:08:58.720,0:09:02.160 +big file + +0:09:00.160,0:09:03.120 +i did is it did a job to tell me that i + +0:09:02.160,0:09:04.240 +haven't answered the question because + +0:09:03.120,0:09:06.320 +someone just + +0:09:04.240,0:09:08.080 +asked me the question well personally if + +0:09:06.320,0:09:08.560 +i were to give you a quick answer in + +0:09:08.080,0:09:11.600 +like + +0:09:08.560,0:09:13.920 +20 seconds personally i think it's a + +0:09:11.600,0:09:15.680 +question that is contextually based + +0:09:13.920,0:09:17.839 +do you want something that is efficient + +0:09:15.680,0:09:21.200 +as far as optimization is concerned + +0:09:17.839,0:09:23.440 +then you need to think about + +0:09:21.200,0:09:24.640 +this and personally for all the + +0:09:23.440,0:09:26.640 +organization that i do + +0:09:24.640,0:09:27.760 +all this stuff all the to-do's that i + +0:09:26.640,0:09:30.080 +handle + +0:09:27.760,0:09:31.519 +i like to do this in one simple big file + +0:09:30.080,0:09:33.760 +because you benefit from all the + +0:09:31.519,0:09:36.320 +refiling capabilities of log mode + +0:09:33.760,0:09:37.200 +so i would do that but for knowledge + +0:09:36.320,0:09:40.080 +management + +0:09:37.200,0:09:41.279 +for note-taking and all this well i'd + +0:09:40.080,0:09:42.959 +much rather follow the + +0:09:41.279,0:09:44.480 +orgrom way of doing things which is + +0:09:42.959,0:09:48.240 +about having many + +0:09:44.480,0:09:50.000 +small files okay i'm not getting any + +0:09:48.240,0:09:52.080 +more questions i'm not sure if there is + +0:09:50.000,0:09:53.040 +one on ise that could be fed to me + +0:09:52.080,0:09:56.399 +otherwise i'm + +0:09:53.040,0:09:57.040 +happy to to uh pass over to the next uh + +0:09:56.399,0:09:59.360 +speaker + +0:09:57.040,0:10:01.360 +and by the way just before i finish your + +0:09:59.360,0:10:04.399 +world is a lie it's not a three-piece + +0:10:01.360,0:10:06.520 +suit i'm wearing jeans below so i hope + +0:10:04.399,0:10:09.610 +that satisfies your curiosity + +0:10:06.520,0:10:09.610 +[Music] + +0:10:10.640,0:10:15.040 +okay there's one more question appearing + +0:10:12.640,0:10:17.680 +but otherwise one big file to have + +0:10:15.040,0:10:19.760 +everything so i'm putting you on the + +0:10:17.680,0:10:21.040 +spot i believe it was such a short talk + +0:10:19.760,0:10:23.600 +you know the problem is + +0:10:21.040,0:10:24.720 +i just wanted to give you a little + +0:10:23.600,0:10:26.959 +answer + +0:10:24.720,0:10:27.920 +a little you know path of thinking on + +0:10:26.959,0:10:29.839 +this topic + +0:10:27.920,0:10:31.600 +but obviously it's a topic i could be + +0:10:29.839,0:10:33.200 +spending 40 minutes on but + +0:10:31.600,0:10:35.120 +i'm going to be drained you're going to + +0:10:33.200,0:10:35.680 +be drained nobody's going to be happy if + +0:10:35.120,0:10:37.920 +i do this + +0:10:35.680,0:10:37.920 +so + +0:10:39.440,0:10:42.880 +and someone asked me if i switch between + +0:10:41.200,0:10:46.560 +british and french accents + +0:10:42.880,0:10:48.480 +so a little a little secret for you um + +0:10:46.560,0:10:49.760 +when i'm stressed i tend to relate to a + +0:10:48.480,0:10:53.760 +french accent + +0:10:49.760,0:10:56.160 +so you can measure the amount of stress + +0:10:53.760,0:10:58.880 +that i'm feeling during this talk + +0:10:56.160,0:11:00.560 +with the amount of h's that i drop and + +0:10:58.880,0:11:02.720 +the amount of uh + +0:11:00.560,0:11:04.399 +sheer fright that you can see sometimes + +0:11:02.720,0:11:07.200 +in my eyes when i'm thinking about what + +0:11:04.399,0:11:07.200 +to say next + +0:11:08.240,0:11:11.360 +all right sir so i mean do you believe + +0:11:10.880,0:11:14.240 +we can + +0:11:11.360,0:11:15.519 +leave it at that and uh i'll be you + +0:11:14.240,0:11:17.040 +people will see plenty more with me + +0:11:15.519,0:11:20.000 +later on anyway + +0:11:17.040,0:11:20.640 +right um so looking at the schedule i + +0:11:20.000,0:11:23.920 +think + +0:11:20.640,0:11:27.120 +your talk has until like 202 meaning + +0:11:23.920,0:11:28.000 +like five or six minutes from now oh + +0:11:27.120,0:11:30.000 +right + +0:11:28.000,0:11:31.680 +yeah so if you do like to take like one + +0:11:30.000,0:11:33.920 +or two questions to add two more + +0:11:31.680,0:11:37.040 +questions by all means + +0:11:33.920,0:11:38.320 +okay so uh someone has asked me what is + +0:11:37.040,0:11:40.640 +the emacs icon + +0:11:38.320,0:11:42.880 +icon sorry see another french accent + +0:11:40.640,0:11:44.880 +here uh in my status bar + +0:11:42.880,0:11:46.640 +uh oh sorry i'm not sharing anymore uh i + +0:11:44.880,0:11:49.200 +might just share again just so that + +0:11:46.640,0:11:53.120 +everyone can catch a glimpse of that + +0:11:49.200,0:11:54.880 +uh there we go allow + +0:11:53.120,0:11:56.240 +so it should be so if you could make me + +0:11:54.880,0:11:56.959 +small again i'm in i'm not sure if it's + +0:11:56.240,0:12:00.480 +going to do it + +0:11:56.959,0:12:01.839 +by itself but i do have a little icon + +0:12:00.480,0:12:04.480 +here in my status bar + +0:12:01.839,0:12:05.760 +which is basically a way to interact + +0:12:04.480,0:12:07.279 +with all protocol + +0:12:05.760,0:12:09.120 +uh i'm not going to look for it right + +0:12:07.279,0:12:10.800 +now but it's uh + +0:12:09.120,0:12:12.399 +it's a browser extension that is + +0:12:10.800,0:12:15.680 +developed by one of my friends + +0:12:12.399,0:12:16.160 +over at ranger whose name is v phone and + +0:12:15.680,0:12:18.240 +uh + +0:12:16.160,0:12:19.680 +it's very useful i'm someone who uses a + +0:12:18.240,0:12:22.320 +lot of uh + +0:12:19.680,0:12:23.040 +of uh all protocols and by the way i + +0:12:22.320,0:12:25.279 +used to teach + +0:12:23.040,0:12:27.279 +english okay to high schoolers and they + +0:12:25.279,0:12:29.600 +were supremely worried + +0:12:27.279,0:12:30.800 +when i show them my status line and they + +0:12:29.600,0:12:34.000 +so kill + +0:12:30.800,0:12:36.560 +and explore in my status line so as + +0:12:34.000,0:12:37.839 +fellow emacs users you know that + +0:12:36.560,0:12:40.880 +obviously kill + +0:12:37.839,0:12:44.320 +means to kill a selection of text and + +0:12:40.880,0:12:47.279 +keep it inside your clipboard + +0:12:44.320,0:12:48.320 +but for my students who you know they + +0:12:47.279,0:12:51.600 +were very worried + +0:12:48.320,0:12:53.600 +about what their professor was up to + +0:12:51.600,0:12:55.120 +doing his nights + +0:12:53.600,0:12:56.560 +so let's see if we've got more questions + +0:12:55.120,0:12:57.920 +so i'm showing you the questions on the + +0:12:56.560,0:13:00.560 +rainbow so let's see if + +0:12:57.920,0:13:01.920 +we've got more so people are posting a + +0:13:00.560,0:13:03.920 +lot of questions now + +0:13:01.920,0:13:06.399 +so how do you feel about archiving files + +0:13:03.920,0:13:09.360 +in old mode and how can that work in + +0:13:06.399,0:13:10.240 +so one of the thing when we think about + +0:13:09.360,0:13:13.920 +optimization + +0:13:10.240,0:13:16.240 +is yes archiving done trees + +0:13:13.920,0:13:17.920 +is a good idea because it means that if + +0:13:16.240,0:13:18.720 +we go back to the org element the way it + +0:13:17.920,0:13:20.399 +works + +0:13:18.720,0:13:22.079 +and we'll get into technical details + +0:13:20.399,0:13:24.079 +afterwards i'm giving a presentation + +0:13:22.079,0:13:26.880 +about all grown technical suspect + +0:13:24.079,0:13:28.399 +aspects sorry so i'll have a chance to + +0:13:26.880,0:13:31.360 +expand a little more on this + +0:13:28.399,0:13:32.160 +but basically all elements need to uh + +0:13:31.360,0:13:35.279 +every time + +0:13:32.160,0:13:38.320 +it sees a to do it has to consider it + +0:13:35.279,0:13:40.000 +even though it is a done to do why + +0:13:38.320,0:13:41.839 +because let's say for instance that in + +0:13:40.000,0:13:45.519 +your agenda you want to activate + +0:13:41.839,0:13:48.959 +log mode which is going to show the + +0:13:45.519,0:13:49.519 +tasks which are done now you could be + +0:13:48.959,0:13:51.440 +clever + +0:13:49.519,0:13:53.360 +and say oh okay the old agenda does not + +0:13:51.440,0:13:54.880 +need to show don items so it's not going + +0:13:53.360,0:13:56.959 +to look for them + +0:13:54.880,0:13:58.720 +but the problem is that all elements is + +0:13:56.959,0:13:59.519 +always called it always needs to pass + +0:13:58.720,0:14:01.839 +the buffer + +0:13:59.519,0:14:03.519 +you know uh nicodego as you who is the + +0:14:01.839,0:14:05.040 +french developer who's worked a whole + +0:14:03.519,0:14:07.440 +lot on all elements + +0:14:05.040,0:14:08.399 +has gone through a lot of trouble to + +0:14:07.440,0:14:11.600 +optimize all + +0:14:08.399,0:14:13.279 +elements but the problem is + +0:14:11.600,0:14:14.720 +there's just so much that we can do with + +0:14:13.279,0:14:18.560 +a concurrent process + +0:14:14.720,0:14:21.120 +and right now it leaves somewhat + +0:14:18.560,0:14:22.079 +uh you know things to be desired but + +0:14:21.120,0:14:24.800 +we're working on it + +0:14:22.079,0:14:25.839 +and one more time i feel like i spent + +0:14:24.800,0:14:28.000 +half of this talk + +0:14:25.839,0:14:29.360 +teasing my next talks but i'll be + +0:14:28.000,0:14:31.279 +talking more about this + +0:14:29.360,0:14:32.639 +in my future talks in about one to two + +0:14:31.279,0:14:34.959 +hours + +0:14:32.639,0:14:36.079 +so continuing with questions how big are + +0:14:34.959,0:14:37.760 +my org files + +0:14:36.079,0:14:39.839 +so in the background i'm just going to + +0:14:37.760,0:14:40.720 +check how many lines i have in my main + +0:14:39.839,0:14:42.959 +file + +0:14:40.720,0:14:44.079 +so in my own file so the one i told you + +0:14:42.959,0:14:47.279 +about where i keep all + +0:14:44.079,0:14:50.720 +my to do gtd stuff i have + +0:14:47.279,0:14:54.000 +38 000 lines which is + +0:14:50.720,0:14:57.040 +you know it's sizable definitely + +0:14:54.000,0:14:58.480 +but i do archive a lot of stuff + +0:14:57.040,0:15:00.880 +so that might be a slight difference + +0:14:58.480,0:15:02.079 +between uh my myself and carl voight + +0:15:00.880,0:15:04.880 +even though i don't remember if they + +0:15:02.079,0:15:06.639 +actually archive stuff + +0:15:04.880,0:15:08.480 +so does it not consume more resources + +0:15:06.639,0:15:10.839 +and time to load multiple files + +0:15:08.480,0:15:12.560 +files than a large file or the same + +0:15:10.839,0:15:15.839 +content now + +0:15:12.560,0:15:19.279 +theoretically yes having many files + +0:15:15.839,0:15:22.240 +open concurrently is slightly slower + +0:15:19.279,0:15:24.160 +than having one main file opened + +0:15:22.240,0:15:25.279 +now the problem is for those of you who + +0:15:24.160,0:15:27.199 +have large files + +0:15:25.279,0:15:29.360 +you may have noticed that when you are + +0:15:27.199,0:15:32.560 +scrolling in a very large file + +0:15:29.360,0:15:34.480 +it starts taking quite a bit of time why + +0:15:32.560,0:15:35.920 +it's because you know in old mode you + +0:15:34.480,0:15:38.959 +have a lot of content + +0:15:35.920,0:15:40.959 +that is hidden so when you have + +0:15:38.959,0:15:43.040 +the view mode which hides as much stuff + +0:15:40.959,0:15:43.600 +as possible means meaning that you only + +0:15:43.040,0:15:45.360 +see + +0:15:43.600,0:15:46.880 +the top heading and i'm checking the + +0:15:45.360,0:15:49.360 +time i mean don't worry i'm i'm finished + +0:15:46.880,0:15:49.360 +on this one + +0:15:50.240,0:15:53.360 +when you're hiding a whole lot of stuff + +0:15:52.160,0:15:54.720 +you know orgmo + +0:15:53.360,0:15:56.959 +needs to keep track or i should say + +0:15:54.720,0:15:58.160 +emacs needs to keep track of which areas + +0:15:56.959,0:16:00.560 +of text to show + +0:15:58.160,0:16:02.320 +and which areas of text to hide and the + +0:16:00.560,0:16:04.480 +problem is that when you're hiding stuff +
