That is maybe 10 seconds + +02:55.200 --> 02:57.599 +of awake time between each request. + +02:57.599 --> 02:58.933 +Cron does not actually run + +02:58.933 --> 02:59.933 +on the Kindle device itself, + +02:59.933 --> 03:01.600 +simply because it does not reliably work. + +03:01.600 --> 03:04.050 +All of this is handled by the server. + +03:04.050 --> 03:05.599 +With the server-client model, + +03:05.599 --> 03:08.000 +it also tries to restrict Amazon access. + +03:08.000 --> 03:09.517 +SSH keys are shared + +03:09.517 --> 03:11.217 +only from the client to the server, + +03:11.217 --> 03:12.517 +but not from the server to the client, + +03:12.517 --> 03:13.920 +so the Kindle cannot connect + +03:13.920 --> 03:16.319 +to the Raspberry Pi without a password. + +03:16.319 --> 03:18.033 +IPtables rules are also set + +03:18.033 --> 03:19.483 +so that the Kindle cannot phone home + +03:19.483 --> 03:20.667 +to Amazon, and the connections + +03:20.667 --> 03:23.200 +are restricted to just the LAN. + +03:23.200 --> 03:24.820 +So I got very curious at one point + +03:24.820 --> 03:26.133 +and decided to see how long + +03:26.133 --> 03:27.599 +a Kindle could last on a single charge + +03:27.599 --> 03:28.560 +in such an arrangement, + +03:28.560 --> 03:30.640 +so that every 15 minutes for 18 hours, + +03:30.640 --> 03:31.599 +I tested the device + +03:31.599 --> 03:32.959 +by sending a media item + +03:32.959 --> 03:35.200 +and recording the battery level. + +03:35.200 --> 03:36.159 +The Kindle doesn't seem to + +03:36.159 --> 03:36.959 +report the battery level + +03:36.959 --> 03:37.760 +very continuously, + +03:37.760 --> 03:39.040 +but at discrete percentages, + +03:39.040 --> 03:39.840 +so that you could end up with + +03:39.840 --> 03:42.159 +a graph that looks like this. + +03:42.159 --> 03:43.617 +Assuming you have half the charge, + +03:43.617 --> 03:45.200 +and use it once every hour - + +03:45.200 --> 03:48.319 +it will drop by 10% battery in 76 hours, + +03:48.319 --> 03:49.760 +which is roughly three days. + +03:49.760 --> 03:50.640 +It's hard to extrapolate + +03:50.640 --> 03:52.400 +with only three good summarized data points, + +03:52.400 --> 03:53.519 +of which the number of requests + +03:53.519 --> 03:54.879 +per battery level appear to diminish + +03:54.879 --> 03:56.640 +as shown in the table below, + +03:56.640 --> 03:58.560 +but the final result yields 76 requests + +03:58.560 --> 04:00.799 +with an average loss of 0.5% battery life + +04:00.799 --> 04:02.273 +per request. Which is not bad! + +04:02.273 --> 04:04.400 +Assuming you do a request every 2 hours + +04:04.400 --> 04:06.000 +from 8am to 8pm, + +04:06.000 --> 04:07.040 +and let it sleep at night, + +04:07.040 --> 04:09.040 +then that's approximately 6 requests a day, + +04:09.040 --> 04:10.400 +which could easily last a device + +04:10.400 --> 04:11.280 +for a month. + +04:11.280 --> 04:12.586 +The ksync script does + +04:12.586 --> 04:13.200 +essentially everything: + +04:13.200 --> 04:14.799 +from generating and fetching the media, + +04:14.799 --> 04:16.720 +to initializing all Kindle devices, + +04:16.720 --> 04:18.160 +generating the server cronjobs, + +04:18.160 --> 04:19.199 +log report summaries, + +04:19.199 --> 04:20.400 +editing the config tables, + +04:20.400 --> 04:21.199 +and much more. + +04:21.199 --> 04:22.880 +The media operations are comparatively + +04:22.880 --> 04:23.680 +much more complex + +04:23.680 --> 04:25.280 +and encompass a few media use cases + +04:25.280 --> 04:26.400 +such as fetching the weather + +04:26.400 --> 04:28.560 +(though only from Open Weather Maps) + +04:28.560 --> 04:30.000 +and retrieving Google Calendar views + +04:30.000 --> 04:32.000 +by week, month, agenda, and four day view. + +04:32.000 --> 04:33.199 +You can retrieve Org-Mode data + +04:33.199 --> 04:34.639 +from an Emacs instance on the server, + +04:34.639 --> 04:35.360 +which in my case + +04:35.360 --> 04:36.720 +I produce views for an agenda + +04:36.720 --> 04:39.360 +or a sparse tree of my main projects file. + +04:39.360 --> 04:41.120 +Finally we have gallery and wavfile, + +04:41.120 --> 04:42.240 +which are static resources + +04:42.240 --> 04:44.000 +which will never change once generated. + +04:44.000 --> 04:45.199 +The idea is that you feed it + +04:45.199 --> 04:46.400 +text and an image location, + +04:46.400 --> 04:47.040 +and it generates + +04:47.040 --> 04:48.720 +a Kindle-compatible image + +04:48.720 --> 04:51.280 +using imagemagick as a backend for it. + +04:51.280 --> 04:52.240 +In the case of the wavfile, + +04:52.240 --> 04:54.160 +it uses espeak on the backend. + +04:54.160 --> 04:55.280 +The below is summarized + +04:55.280 --> 04:56.317 +from the help-me text + +04:56.317 --> 04:57.199 +in the main ksync file, + +04:57.199 --> 04:58.160 +but essentially, you need to + +04:58.160 --> 04:59.919 +define your config in the CSV files, + +04:59.919 --> 05:01.440 +which we talk about in the next section; + +05:01.440 --> 05:03.120 +initialize all your Kindle devices, + +05:03.120 --> 05:04.720 +i.e. copy over SSH keys, + +05:04.720 --> 05:06.160 +kill all the unnecessary services, + +05:06.160 --> 05:07.840 +and prime them for media collection; + +05:07.840 --> 05:08.720 +and ensure that you have + +05:08.720 --> 05:10.080 +all your static media generated + +05:10.080 --> 05:11.440 +and fetchable; and finally + +05:11.440 --> 05:12.720 +you then refresh the scheduling + +05:12.720 --> 05:14.240 +on the server. + +05:14.240 --> 05:15.759 +Okay, so this is all good and well, + +05:15.759 --> 05:17.039 +and we now know what the server does + +05:17.039 --> 05:18.400 +and how to probe and inspect it - + +05:18.400 --> 05:19.759 +but how does the server generate + +05:19.759 --> 05:21.120 +much of the content? + +05:21.120 --> 05:22.080 +So a lot of the content + +05:22.080 --> 05:23.360 +will be dynamically generated, + +05:23.360 --> 05:24.639 +meaning it cannot be cached + +05:24.639 --> 05:26.720 +and is likely to change from hour to hour. + +05:26.720 --> 05:28.400 +The media content that is generated here + +05:28.400 --> 05:29.759 +are mostly PNG images + +05:29.759 --> 05:30.567 +and have a timestamp + +05:30.567 --> 05:32.320 +embedded in their filenames. + +05:32.320 --> 05:33.520 +The Emacs-specific content + +05:33.520 --> 05:34.560 +consists of a few views, + +05:34.560 --> 05:36.000 +namely the org-gcal views, + +05:36.000 --> 05:37.600 +org-agenda, and org-calories -- + +05:37.600 --> 05:39.520 +essentially anything that Emacs can display + +05:39.520 --> 05:42.000 +and that you want to capture into an image. + +05:42.000 --> 05:43.360 +Emacs can't (as far as I know) + +05:43.360 --> 05:44.639 +render graphics in a headless way, + +05:44.639 --> 05:45.600 +so what we do instead + +05:45.600 --> 05:48.240 +is run Emacs in a dummy minimal X11 session + +05:48.240 --> 05:50.080 +via "xvrb-run." + +05:50.080 --> 05:51.680 +From inside, you can take screenshots + +05:51.680 --> 05:52.233 +as you would in + +05:52.233 --> 05:53.440 +a normal desktop environment, + +05:53.440 --> 05:54.400 +but with the benefit that + +05:54.400 --> 05:56.479 +you don't actually need to invoke a desktop + +05:56.479 --> 05:58.560 +or interfere with an existing one. + +05:58.560 --> 05:59.840 +The minimal elisp shown here + +05:59.840 --> 06:00.720 +is all that is required + +06:00.720 --> 06:02.400 +to output your desired image from Emacs + +06:02.400 --> 06:04.479 +and configure it for the Kindle environment. + +06:04.479 --> 06:05.360 +On the web side of things, + +06:05.360 --> 06:06.400 +we don't really need to invoke + +06:06.400 --> 06:07.520 +a dummy X11 session + +06:07.520 --> 06:09.120 +because Chromium can run headless + +06:09.120 --> 06:09.919 +and can be controlled + +06:09.919 --> 06:11.600 +by the node library "puppeteer" + +06:11.600 --> 06:13.039 +to render dynamic content, + +06:13.039 --> 06:14.560 +focus on regions of the webpage, + +06:14.560 --> 06:16.080 +and take snapshots. + +06:16.080 --> 06:17.600 +The static content comprises + +06:17.600 --> 06:19.600 +of two types: images and audio. + +06:19.600 --> 06:21.520 +The content is accessed by a key, + +06:21.520 --> 06:22.560 +in this case Batman, + +06:22.560 --> 06:23.600 +and the content information + +06:23.600 --> 06:25.199 +is given by the "--extra" parameter + +06:25.199 --> 06:26.960 +which describes either or both + +06:26.960 --> 06:30.880 +an image and text. + +06:30.880 --> 06:32.248 +Okay, so now we have content, + +06:32.248 --> 06:33.600 +how do we schedule this content + +06:33.600 --> 06:34.960 +to appear on our desired machines + +06:34.960 --> 06:36.400 +at desired times? + +06:36.400 --> 06:37.759 +Everything is run via cron. + +06:37.759 --> 06:38.720 +So previously we saw that + +06:38.720 --> 06:40.880 +we only needed the tables MACHINES.csv, + +06:40.880 --> 06:43.440 +COMMANDS.csv, and multiple TIME_*.csv tables + +06:43.440 --> 06:44.880 +for the shell script to work. + +06:44.880 --> 06:46.479 +But Org-Mode does this far easier, + +06:46.479 --> 06:47.919 +since you can just have everything + +06:47.919 --> 06:49.039 +in the same file, + +06:49.039 --> 06:50.720 +and with the helper minor-mode, + +06:50.720 --> 06:51.360 +manage everything + +06:51.360 --> 06:53.120 +from a single Org-Mode document. + +06:53.120 --> 06:55.120 +Here I have 4 kindles and their shortnames. + +06:55.120 --> 06:56.160 +Yes, I even have a Kindle + +06:56.160 --> 06:57.520 +hanging outside my door. + +06:57.520 --> 06:58.960 +I have 11 defined commands + +06:58.960 --> 07:00.800 +which represent the views I want to see, + +07:00.800 --> 07:02.319 +and there are 4 timetables I use, + +07:02.319 --> 07:02.800 +but you can have + +07:02.800 --> 07:04.319 +everything on one, if you like. + +07:04.319 --> 07:05.360 +Rows are machine names, + +07:05.360 --> 07:06.800 +and columns are corresponding hours + +07:06.800 --> 07:07.840 +at which they run. + +07:07.840 --> 07:09.440 +Trust me, it's easier to configure + +07:09.440 --> 07:10.960 +repeating tasks just by repeating them + +07:10.960 --> 07:12.720 +multiple times, because at least this way, + +07:12.720 --> 07:13.680 +it's human readable, + +07:13.680 --> 07:14.880 +and the script which converts these + +07:14.880 --> 07:15.759 +to a cronjob + +07:15.759 --> 07:18.800 +collapses the repeating tasks by itself. + +07:18.800 --> 07:20.560 +The ksync script can be called + +07:20.560 --> 07:23.120 +from within the config.org file + +07:23.120 --> 07:24.683 +using this convenient + +07:24.683 --> 07:26.960 +use-package declaration. + +07:26.960 --> 07:28.319 +All that one needs to do + +07:28.319 --> 07:30.560 +is to configure the ENVIRONMENT_VARIABLES + +07:30.560 --> 07:32.880 +by setting them in this table + +07:32.880 --> 07:34.479 +where you set the repo name, + +07:34.479 --> 07:36.160 +the config directory, + +07:36.160 --> 07:37.599 +where the media shall go, + +07:37.599 --> 07:38.960 +and the server IP, + +07:38.960 --> 07:39.919 +although this can be + +07:39.919 --> 07:41.360 +automatically detected. + +07:41.360 --> 07:42.240 +The package allows you + +07:42.240 --> 07:43.440 +to export your tables + +07:43.440 --> 07:46.720 +by running C-c C-c on them, + +07:46.720 --> 07:49.199 +and allows you to update all the jobs + +07:49.199 --> 07:52.319 +related to each of your clients. + +07:52.319 --> 07:53.759 +You can also initialize clients + +07:53.759 --> 07:55.120 +using this package -- + +07:55.120 --> 07:56.479 +for either all of them + +07:56.479 --> 07:58.479 +or individual clients -- + +07:58.479 --> 07:59.599 +and the package comes with + +07:59.599 --> 08:01.120 +some convenience functions + +08:01.120 --> 08:02.720 +to do this automatically + +08:02.720 --> 08:06.720 +for all tables in the buffer. + +08:06.720 --> 08:08.319 +With this, I want to say a big thank you + +08:08.319 --> 08:09.840 +to Takaaki Ishikawa + +08:09.840 --> 08:11.520 +for his fantastic "org-tree-slide" + +08:11.520 --> 08:12.879 +presentation package. + +08:12.879 --> 08:14.136 +To Pascal Widdershoven + +08:14.136 --> 08:15.803 +and David Hamp-Gonsalves, + +08:15.803 --> 08:16.633 +for their fantastic + +08:16.633 --> 08:17.840 +kindle-dash repositories, + +08:17.840 --> 08:19.903 +for which some of my internal Kindle scripts + +08:19.903 --> 08:20.720 +are derived from. + +08:20.720 --> 08:22.160 +Also a big thanks to the friendly + +08:22.160 --> 08:23.520 +and not-so-friendly users and hackers + +08:23.520 --> 08:24.960 +in the MobileRead forums. + +08:24.960 --> 08:25.919 +And finally, a big thanks + +08:25.919 --> 08:26.960 +to the Emacs community + +08:26.960 --> 08:28.270 +and the conference organizers. + +08:28.270 --> 08:31.120 +Thank you!

00:00:19.039 +First, I need to introduce the way + +00:00:19.039 --> 00:00:21.279 +in which we build our project budget. + +00:21.279 --> 00:00:22.480 +We start from the goals + +00:00:22.480 --> 00:00:24.720 +and the work to be performed, + +00:24.720 --> 00:00:29.840 +and we split it into different tasks + +00:29.840 --> 00:00:31.920 +which may be grouped in different ways, + +00:31.920 --> 00:00:33.440 +according to our needs. + +00:00:33.440 --> 00:00:36.800 +It could be user stories or functional groups + +00:00:36.800 --> 00:00:40.719 +or packages, and then for each task, + +00:00:40.719 --> 00:00:44.000 +we compute the effort. + +00:44.000 --> 00:00:45.440 +Then from the effort, + +00:00:45.440 --> 00:00:49.840 +we derive the project cost and price + +00:49.840 --> 00:00:52.239 +according to two different approaches. + +00:52.239 --> 00:00:53.280 +The first approach: + +00:00:53.280 --> 00:00:56.320 +we allocate the effort to each resource + +00:56.320 --> 00:00:59.680 +and we multiply the effort of the resource + +00:00:59.680 --> 00:01:01.359 +by the price of the results. + +00:01:01.359 --> 00:01:04.320 +We sum all the efforts together, + +00:01:04.320 --> 00:01:07.280 +and then we sum all the tasks together, + +00:01:07.280 --> 00:01:09.600 +the prices of all the tasks together. + +00:01:09.600 --> 00:01:11.200 +In the second approach, + +00:01:11.200 --> 00:01:16.400 +we use a generic effort estimation + +00:01:16.400 --> 00:01:20.799 +for each task, without allocating the effort + +00:01:20.799 --> 00:01:22.560 +to any specific person, + +00:01:22.560 --> 00:01:25.119 +and we multiply this effort + +00:01:25.119 --> 00:01:29.040 +by the average price of the resource. + +01:29.040 --> 00:01:34.720 +In both cases, the price is computed + +01:34.720 --> 00:01:40.079 +by summing cost to overheads and profit. + +00:01:40.079 --> 00:01:41.040 +We're a small company. + +00:01:41.040 --> 00:01:42.719 +We can choose our toolchain. + +00:01:42.720 --> 00:01:44.960 +So we decided to use Org mode + +00:01:44.960 --> 00:01:47.360 +for writing our proposals. + +01:47.360 --> 00:01:49.200 +We built a template. + +00:01:49.200 --> 00:01:54.159 +The template has got a fixed structure + +01:54.159 --> 00:01:56.880 +which allows us to do a lot of reuse, + +01:56.880 --> 00:01:59.600 +and some Emacs Lisp code + +00:01:59.600 --> 00:02:01.040 +and Org mode features + +00:02:01.040 --> 00:02:04.079 +to build the project tables. + +00:02:04.079 --> 00:02:07.600 +Let me show you, without further ado, + +00:02:07.600 --> 00:02:11.760 +the template which is shown here. + +02:11.760 --> 00:02:15.520 +Basically it is a fairly standard + +02:15.520 --> 00:02:17.750 +Org mode document. + +02:20.800 --> 00:02:23.760 +There are some sections here. + +02:23.760 --> 00:02:28.879 +Let me show you the structure here. + +02:28.879 --> 00:02:30.000 +There are some sections, + +00:02:30.000 --> 00:02:34.959

proposal. + +00:02:58.400 --> 00:03:00.400 +Now the structure is not really important + +00:03:00.400 --> 00:03:02.720 +in the sense that the only constraint + +00:03:02.720 --> 00:03:05.360 +and requirement we set + +00:03:05.360 --> 00:03:07.599 +is that there has to be a section + +03:07.599 --> 00:03:10.800 +with an ID named plan, + +03:10.800 --> 00:03:15.840 +which will contain the project plan. + +03:15.840 --> 00:03:21.040 +Here, for instance, we have a project plan + +00:03:21.040 --> 00:03:23.599 +made of a user story + +03:23.599 --> 00:03:25.360 +whose development is split into + +00:03:25.360 --> 00:03:27.360 +three different tasks. + +03:27.360 --> 00:03:30.080 +For each task, let me show you + +00:03:30.080 --> 00:03:33.200 +just the structure + +00:03:33.200 --> 00:03:37.279 +before the application of the template. + +03:37.280 --> 00:03:45.200 +For each task, you need to define the effort. + +00:03:45.200 --> 00:03:47.360 +Here, for instance, we have an effort, + +00:03:47.360 --> 00:03:50.480 +a generic effort not allocated to any person. + +03:50.480 --> 00:03:52.400 +We use Org mode duration, + +00:03:52.400 --> 00:03:54.799 +60 stands for 60 minutes, + +03:54.799 --> 00:03:57.680 +and here we have an effort profile. + +00:03:57.680 --> 00:04:02.000 +So in task 1.2, Adolfo will work 10 days + +00:04:02.000 --> 00:04:04.159 +and Michele 20 days. + +04:04.159 --> 00:04:06.000 +These are working days, + +00:04:06.000 --> 00:04:07.439 +so one working day + +00:04:07.439 --> 00:04:09.760 +corresponds to eight hours. + +04:09.760 --> 00:04:13.519 +This is standard. We might revise these + +04:13.519 --> 00:04:15.040 +to become more compliant + +00:04:15.040 --> 00:04:19.759 +with the definition given by Org mode. + +00:04:19.759 --> 00:04:23.040 +Notice that you can or cannot, + +00:04:23.040 --> 00:04:26.720 +you may or may not use TODO keywords here, + +00:04:26.720 --> 00:04:29.199 +if you want. We don't usually use them + +00:04:29.199 --> 00:04:31.360 +because the final document + +00:04:31.360 --> 00:04:34.720 +looks nice to the customer without TODO. + +00:04:34.720 --> 00:04:38.479 +We then add them when we move to + +00:04:38.479 --> 00:04:40.719 +a later stage. + +04:40.720 --> 00:04:43.040 +So once you define the plan + +00:04:43.040 --> 00:04:45.600 +with the effort allocation, + +04:45.600 --> 00:04:51.440 +you can go back to the Emacs Lisp part + +00:04:51.440 --> 00:04:55.680 +where you can set three different variables + +04:55.680 --> 00:04:59.680 +to define the hourly rates of your team. + +04:59.680 --> 00:05:02.880 +So for instance, here I am taking + +00:05:02.880 --> 00:05:06.160 +10 euros per hour + +00:05:06.160 --> 00:05:09.680 +(not real rate, actually), and Michele at 20. + +05:09.680 --> 00:05:11.360 +And then you can set the profit + +00:05:11.360 --> 00:05:14.560 +as a percentage on top of the hourly rate + +00:05:14.560 --> 00:05:16.160 +and profit as a percentage + +00:05:16.160 --> 00:05:19.360 +on top of hourly rates. + +05:19.360 --> 00:05:24.000 +The ballpark effort allocation here + +00:05:24.000 --> 00:05:28.880 +is used to compute the average tariff, + +05:28.880 --> 00:05:32.160 +our average hourly rate, + +05:32.160 --> 00:05:33.600 +as a weighted average. + +00:05:33.600 --> 00:05:36.320 +So here I'm saying that on average, + +00:05:36.320 --> 00:05:40.639 +I will work 30% of the effort of each task, + +00:05:40.639 --> 00:05:42.400 +while Michele will take care of + +00:05:42.400 --> 00:05:47.280 +the remaining 70%, and the hourly rate + +00:05:47.280 --> 00:05:48.720 +is computed by multiplying + +00:05:48.720 --> 00:05:57.120 +30% by 10 + 70% by 20. + +05:57.120 --> 00:06:00.880 +If I do a C-c C-c here, I execute + +00:06:00.880 --> 00:06:05.440 +the Emacs Lisp code + +00:06:05.440 --> 00:06:07.439 +in the source code block. + +00:06:07.440 --> 00:06:08.880 +As you can see, + +00:06:08.880 --> 00:06:15.759 +Emacs put back the properties + +06:15.759 --> 00:06:17.840 +that transform the effort + +00:06:17.840 --> 00:06:19.600 +into a total amount: + +00:06:19.600 --> 00:06:22.800 +namely, the effort is first transformed + +00:06:22.800 --> 00:06:24.479 +into working hours, + +06:24.479 --> 00:06:27.280 +the rates and costs are computed, + +06:27.280 --> 00:06:28.880 +overhead computed, + +00:06:28.880 --> 00:06:32.160 +and everything contributes + +00:06:32.160 --> 00:06:34.639 +to the total amount. + +06:34.639 --> 00:06:37.600 +Same thing here. + +00:06:37.600 --> 00:06:41.440 +The cost is slightly more complex + +00:06:41.440 --> 00:06:45.360 +because we use profiled effort, + +06:45.360 --> 00:06:47.199 +and so on and so forth. + +00:06:47.199 --> 00:06:49.680 +This information here + +00:06:49.680 --> 00:06:56.960 +can be then grouped up + +06:56.960 --> 00:06:59.759 +to form the project plan + +00:06:59.759 --> 00:07:01.599 +and project budget. + +00:07:01.599 --> 00:07:03.039 +As you can see, + +07:03.039 --> 00:07:06.880 +this is something we do not export + +07:06.880 --> 00:07:09.440 +in the project proposal to the client, + +07:09.440 --> 00:07:10.880 +because we prefer to do + +00:07:10.880 --> 00:07:13.199 +some rounding by hand + +07:13.199 --> 00:07:14.880 +in order to build a budget + +00:07:14.880 --> 00:07:20.880 +which is, let's say, more reasonable. + +07:20.880 --> 00:07:24.639 +This table here computes VAT + +00:07:24.639 --> 00:07:28.159 +on total amounts by C-c C-c once again. + +00:07:28.160 --> 00:07:31.120 +Then this table here, the payment structure + +00:07:31.120 --> 00:07:36.080 +is used to compute the amount to be paid + +00:07:36.080 --> 00:07:39.280 +according to the different payments + +00:07:39.280 --> 00:07:40.800 +we want to set in the project. + +00:07:40.800 --> 00:07:42.160 +Here, for instance, we are setting + +00:07:42.160 --> 00:07:45.919 +three payments with the following percentages, + +00:07:45.919 --> 00:07:49.199 +and the table, you set the dates and amounts, + +00:07:49.199 --> 00:07:53.440 +and the table keeps track of the rest + +00:07:53.440 --> 00:07:56.479 +by looking at the total amount + +07:56.479 --> 00:08:00.800 +it finds here in the budget table, + +00:08:00.800 --> 00:08:03.280 +so the payment structure and budget + +00:08:03.280 --> 00:08:07.280 +are then used by this piece of code here + +08:07.280 --> 00:08:12.000 +to build the entries + +00:08:12.000 --> 00:08:16.720 +used for our internal accounting, + +08:16.720 --> 00:08:21.038 +which is based on hledger. + +08:21.039 --> 00:08:23.759 +We did everything here by hand, + +08:23.759 --> 00:08:26.400 +but it is not necessary, of course, + +08:26.400 --> 00:08:31.280 +because if you export the document + +00:08:31.280 --> 00:08:34.880 +using C-c C-e and then, for instance, + +00:08:34.880 --> 00:08:39.760 +l for LaTeX and p for PDF, + +08:39.760 --> 00:08:43.279 +Org mode takes care of evaluating + +00:08:43.279 --> 00:08:46.480 +each piece of code in the document + +00:08:46.480 --> 00:08:50.720 +and generate the updated documents. + +00:08:50.720 --> 00:08:52.000 +Here, for instance, you can see + +00:08:52.000 --> 00:08:55.680 +that the PDF generated from the template + +00:08:55.680 --> 00:08:57.440 +which contains all the tables, budget, + +00:08:57.440 --> 00:08:59.920 +and payment schema, everything, + +00:08:59.920 --> 00:09:02.240 +which we use to make an offer + +00:09:02.240 --> 00:09:07.999 +to our clients. + +09:08.000 --> 00:09:10.000 +There are various advantages, + +00:09:10.000 --> 00:09:12.640 +the first, the main one being that + +00:09:12.640 --> 00:09:15.600 +we keep all the information in one place, + +09:15.600 --> 00:09:17.920 +and that we can version + +00:09:17.920 --> 00:09:20.399 +the different versions. + +00:09:20.399 --> 00:09:21.680 +You can use source control + +00:09:21.680 --> 00:09:24.640 +to version different iterations + +00:09:24.640 --> 00:09:26.080 +on the document. + +09:26.080 --> 00:09:28.000 +If you want, you can find the document here. + +00:09:28.000 --> 00:09:33.120 +Thank you for your
