I'm Joseph + +00:00:03.920 --> 00:00:07.439 +Turner presenting on behalf of Ushin, a tiny independent + +00:00:07.440 --> 00:00:12.039 +information freedom nonprofit. Hyperdrive.el is an Emacs + +00:00:12.040 --> 00:00:14.959 +interface to the Hyperdrive peer-to-peer file sharing + +00:00:14.960 --> 00:00:18.399 +system built by HolePunch. Like other peer-to-peer file + +00:00:18.400 --> 00:00:22.119 +sharing tools, such as BitTorrent, Hyperdrive lets you + +00:00:22.120 --> 00:00:25.959 +share unlimited files directly with other users without + +00:00:25.960 --> 00:00:29.519 +having to go through a central hub. One thing that sets + +00:00:29.520 --> 00:00:32.519 +HyperDrive apart is that the files you share can be + +00:00:32.520 --> 00:00:35.759 +modified. Since Hyperdrive has built-in versioning, + +00:00:35.760 --> 00:00:38.519 +you can explore the history of changes that you make to your + +00:00:38.520 --> 00:00:42.199 +files or others make to theirs. You can stream video and + +00:00:42.200 --> 00:00:45.639 +audio. There's no sign-up or account creation process + +00:00:45.640 --> 00:00:49.319 +required. It's all free software. This means that the + +00:00:49.320 --> 00:00:52.319 +community has the legal right, the tools, and the + +00:00:52.320 --> 00:00:55.359 +information necessary to participate in the development + +00:00:55.360 --> 00:00:58.337 +process, or even fork the project + +00:00:58.338 --> 00:01:00.799 +and go somewhere on[??]. Since + +00:01:00.800 --> 00:01:04.919 +last year's talk, we've added a few new features. It's now + +00:01:04.920 --> 00:01:08.559 +much easier to get started using hyperdrive.el, since we + +00:01:08.560 --> 00:01:12.399 +added the hyperdrive install command, which downloads the + +00:01:12.400 --> 00:01:16.399 +gateway program and installs it on your machine. We added a + +00:01:16.400 --> 00:01:19.959 +peer graph feature, which lets you visualize your network + +00:01:19.960 --> 00:01:24.719 +of sources of information. We also published a new package, + +00:01:24.720 --> 00:01:29.079 +hyperdrive-org-transclusion, which lets you display live + +00:01:29.080 --> 00:01:34.599 +updating snippets of Hyperdrive files in Org documents. + +00:01:34.600 --> 00:01:37.319 +Let's get started. Let's say you get an email from your + +00:01:37.320 --> 00:01:41.079 +friend Alice inviting you to check out hyperdrive.el. + +00:01:41.080 --> 00:01:45.519 +Let's click on the link here to look at the manual. Let's go + +00:01:45.520 --> 00:01:50.239 +down to the installation section. It says you need to have + +00:01:50.240 --> 00:01:54.639 +GNU Emacs version 28.1 or later. I'll assume you have it + +00:01:54.640 --> 00:01:57.479 +installed, but if not, you can click this link. + +00:01:57.480 --> 00:01:59.399 +You need to have curl installed, + +00:01:59.400 --> 00:02:01.919 +which is likely already the case, but if not, + +00:02:01.920 --> 00:02:04.719 +hyperdrive.el will let you know. + +00:02:04.720 --> 00:02:10.879 +Now from within Emacs you can install hyperdrive.el. + +00:02:10.880 --> 00:02:14.399 +Run M-x package-refresh-contents. + +00:02:14.400 --> 00:02:20.919 +Then, M-x package-install, type in hyperdrive, + +00:02:20.920 --> 00:02:26.079 +and hit return. Next, we'll install hypergateway ushin. + +00:02:26.080 --> 00:02:32.999 +Let's run M-x hyperdrive-install. It's prompting me to + +00:02:33.000 --> 00:02:35.880 +download and install the gateway, which is 51 megabytes. + +00:02:35.881 --> 00:02:39.780 +I'll press y. + +00:02:39.781 --> 00:02:44.159 +I will skip most of the download process. The download is + +00:02:44.160 --> 00:02:49.439 +wrapping up. + +00:02:49.440 --> 00:02:53.399 +Now, it's prompting me to start the gateway. I can either run + +00:02:53.400 --> 00:02:59.279 +M-x hyperdrive start, or I can press this button. And + +00:02:59.280 --> 00:03:03.479 +after a few moments, we'll see that the gateway will start. + +00:03:03.480 --> 00:03:07.279 +It's ready. You can also click this button, View Hyperdrive + +00:03:07.280 --> 00:03:10.239 +User Info Manual, to view the same manual that we were + +00:03:10.240 --> 00:03:13.479 +viewing in the browser. The info manual comes with + +00:03:13.480 --> 00:03:17.319 +hyperdrive.el and is available offline. Now that + +00:03:17.320 --> 00:03:20.559 +everything's installed and the gateway is running, we're + +00:03:20.560 --> 00:03:23.399 +back at Alice's email. Let's click on the link to her + +00:03:23.400 --> 00:03:28.719 +hyperdrive. Here's Alice's hyperdrive. Let's open her + +00:03:28.720 --> 00:03:33.079 +hello.org file. + +00:03:33.080 --> 00:03:37.319 +I'm being prompted to mark Alice's hyperdrive. Currently, + +00:03:37.320 --> 00:03:41.879 +it's unknown. I'll press ? to see more details. + +00:03:41.880 --> 00:03:48.279 +Safe, unsafe, unknown. I'll press e for explain. In the info + +00:03:48.280 --> 00:03:54.139 +manual, it says that if a hyperdrive is marked as safe, that + +00:03:54.140 --> 00:03:57.799 +means files in that hyperdrive will automatically have + +00:03:57.800 --> 00:04:02.559 +their major mode enabled based on their file extension. In + +00:04:02.560 --> 00:04:06.719 +this case, if I mark Alice's hyperdrive as safe and I click on + +00:04:06.720 --> 00:04:10.519 +this hello.org file, Emacs will automatically enable org + +00:04:10.520 --> 00:04:14.919 +mode in that file. Since I know Alice directly, I'll mark her + +00:04:14.920 --> 00:04:19.639 +hyperdrive as safe. I'll click on the file hello.org again, + +00:04:19.640 --> 00:04:25.679 +and now I'll press Shift-s for safe. + +00:04:25.680 --> 00:04:30.639 +Now I'm going to set Alice's pet name. Hyperdrive.el has + +00:04:30.640 --> 00:04:34.679 +different ways to name a hyperdrive. The public key is the + +00:04:34.680 --> 00:04:38.719 +drive's unique identifier. You can also assign yourself a + +00:04:38.720 --> 00:04:42.359 +public nickname, which you announce to the world. Then + +00:04:42.360 --> 00:04:45.959 +users on their own machines can assign each hyperdrive that + +00:04:45.960 --> 00:04:50.439 +they are aware of a private pet name. I'll assign Alice a + +00:04:50.440 --> 00:04:54.079 +pet name, which is the way that I will identify Alice just on + +00:04:54.080 --> 00:05:01.906 +my own machine. I'll type in my friend Alice. + +00:05:01.907 --> 00:05:03.707 +Then when I refresh her drive, + +00:05:03.708 --> 00:05:07.359 +we see that it says pet name in the top left. + +00:05:07.360 --> 00:05:09.392 +Now I'll do what she asks, + +00:05:09.393 --> 00:05:11.613 +which is to right click on her name and + +00:05:11.614 --> 00:05:15.259 +open her peer graph. In the context menu, I see a few + +00:05:15.260 --> 00:05:19.159 +different actions I can take, but I'll click on peer graph. + +00:05:19.160 --> 00:05:22.959 +It's prompting me to pick the max hops for sources. Default + +00:05:22.960 --> 00:05:26.799 +3. I'll choose the default. Same for blockers. I'll explain + +00:05:26.800 --> 00:05:27.599 +what that means later. + +00:05:30.380 --> 00:05:35.959 +This is Alice's peer graph. Here we can see that Alice has two + +00:05:35.960 --> 00:05:41.279 +direct sources, Bob and Eve. Both Bob and Eve have assigned + +00:05:41.280 --> 00:05:45.919 +themselves nicknames, and so we see Bob and Eve here. Eve has + +00:05:45.920 --> 00:05:50.479 +assigned this other hyperdrive to be a source. But this + +00:05:50.480 --> 00:05:55.959 +other hyperdrive, whose public key is KB3ZR6MQ + +00:05:55.960 --> 00:05:59.519 +and so on--if we hover over the hyperdrive, we'll see the full + +00:05:59.520 --> 00:06:03.239 +public key--has not assigned itself a nickname. So we + +00:06:03.240 --> 00:06:07.999 +just see the truncated short public key. Because we've + +00:06:08.000 --> 00:06:10.917 +assigned a pet name for Alice, + +00:06:10.918 --> 00:06:14.558 +we see Alice's pet name show up here. + +00:06:14.559 --> 00:06:17.839 +Now I'll open the peer list view to show the same + +00:06:17.840 --> 00:06:21.479 +information in a different way. Since I'm using a large + +00:06:21.480 --> 00:06:25.199 +font, I'll widen this window so we can see everything going + +00:06:25.200 --> 00:06:29.319 +on in the peer list. We see that the root hyperdrive is pet + +00:06:29.320 --> 00:06:33.639 +name, my friend Alice, nickname Alice, public key, DM1, and + +00:06:33.640 --> 00:06:38.359 +so on. We've set the sources max hops to three, which means + +00:06:38.360 --> 00:06:42.359 +that we will go out at most three hops from Alice in order to + +00:06:42.360 --> 00:06:49.839 +find sources. One hop from Alice are Bob and Eve. One hop + +00:06:49.840 --> 00:06:55.839 +from Eve is KB3, which is two hops from Alice. Now we've set + +00:06:55.840 --> 00:06:59.159 +the max hops for sources to three, but in this case, the + +00:06:59.160 --> 00:07:04.279 +network is small, and KB3 has no sources. So we can only go + +00:07:04.280 --> 00:07:07.959 +out two hops from Alice until we run out of sources. In the + +00:07:07.960 --> 00:07:11.159 +future, we plan to add a search feature based on this list of + +00:07:11.160 --> 00:07:14.479 +sources. You type in a query, and you get back a list of + +00:07:14.480 --> 00:07:19.879 +results published by Eve, Bob, or KB3. It's also possible to + +00:07:19.880 --> 00:07:23.239 +block peers. I'll open the transient menu by pressing + +00:07:23.240 --> 00:07:28.759 +question mark. For now, let's turn on showing blocked + +00:07:28.760 --> 00:07:35.439 +peers. I'll press s x, and now it says blocked sources. + +00:07:35.440 --> 00:07:38.839 +Now we can see Mallory also shows up. Mallory has been + +00:07:38.840 --> 00:07:43.399 +included as a source by Eve, but is blocked. So in the end + +00:07:43.400 --> 00:07:47.039 +result, she does not show up in the list of sources. Instead, + +00:07:47.040 --> 00:07:51.839 +she shows up as a blocked source. But how is it that Mallory + +00:07:51.840 --> 00:07:55.039 +ended up being blocked? Let's open up the transient menu + +00:07:55.040 --> 00:08:02.759 +once more and click S, B to show blockers. Now we can see that + +00:08:02.760 --> 00:08:07.079 +Bob has blocked Mallory. This means that Bob is not + +00:08:07.080 --> 00:08:12.519 +interested in seeing search results from Mallory. Since + +00:08:12.520 --> 00:08:17.639 +Alice has included Bob as a blocker, that means that Alice + +00:08:17.640 --> 00:08:23.439 +trusts Bob to block people on her behalf. So since Bob has + +00:08:23.440 --> 00:08:27.479 +blocked Mallory, Mallory does not show up in Alice's + +00:08:27.480 --> 00:08:31.919 +peergraph as a source. Well, now I'm curious to see what it is + +00:08:31.920 --> 00:08:35.919 +Mallory published that drove Bob to block her. I'll + +00:08:35.920 --> 00:08:39.439 +right-click on Mallory, and in the context menu, open + +00:08:39.440 --> 00:08:44.319 +Hyperdrive, and... Wingsuit Flying Grand Canyon Point of + +00:08:44.320 --> 00:08:49.879 +View Not Clickbait? I gotta check this out. + +00:08:49.880 --> 00:08:56.159 +No! Disgusting! No wonder Bob blocked Mallory. Let's go + +00:08:56.160 --> 00:09:01.839 +back to Alice's paragraph. Mallory is a blocked source. + +00:09:01.840 --> 00:09:05.599 +Are there any peers who are blocked but who aren't sources? + +00:09:05.600 --> 00:09:11.739 +I'll open the transient menu and I'll press s x. Now we're + +00:09:11.740 --> 00:09:16.839 +looking at blocked non-sources. Darth, who's been blocked + +00:09:16.840 --> 00:09:20.759 +by Bob, has not been added by any of Alice's sources as a + +00:09:20.760 --> 00:09:25.559 +source. So Darth is a blocked non-source. I'll open the + +00:09:25.560 --> 00:09:29.699 +transient menu again and I'll press s x. Now we're + +00:09:29.700 --> 00:09:34.639 +looking at all blocked peers. Both Mallory and Darth show + +00:09:34.640 --> 00:09:37.959 +up. If I scroll down in the peer list, we'll see that Mallory + +00:09:37.960 --> 00:09:42.519 +is listed under blocked sources, and Darth is listed under + +00:09:42.520 --> 00:09:45.559 +blocked non-sources. This view has gotten a little bit + +00:09:45.560 --> 00:09:49.319 +busy. Let's say that we're only interested in how Alice + +00:09:49.320 --> 00:09:54.519 +relates to Mallory. I'll open the transient menu, and I + +00:09:54.520 --> 00:09:58.519 +will filter the graph to show paths only to Mallory. I'll + +00:09:58.520 --> 00:10:05.519 +press o a, type in Mallory, and hit enter. Now we see that + +00:10:05.520 --> 00:10:11.479 +Mallory has a bold border and KB3 and Darth are missing from + +00:10:11.480 --> 00:10:16.679 +the graph. Eve shows up because there's a path from Alice to + +00:10:16.680 --> 00:10:22.479 +Mallory that goes through Eve. Same for Bob. We can also add + +00:10:22.480 --> 00:10:28.599 +more than one peer in this view. I'll press OA again, and + +00:10:28.600 --> 00:10:34.719 +this time I'll choose Darth. Now Darth and Mallory have bold + +00:10:34.720 --> 00:10:38.839 +borders, and KB3 is still missing. We can remove Mallory and + +00:10:38.840 --> 00:10:42.799 +Darth one at a time with o r, or we can press C-u, the + +00:10:42.800 --> 00:10:47.679 +universal prefix argument, and then o r to remove both + +00:10:47.680 --> 00:10:51.239 +Mallory and Darth from the list. Now we're back to seeing + +00:10:51.240 --> 00:10:55.679 +everybody. This view of the graph is somewhat simplified + +00:10:55.680 --> 00:10:57.537 +because we're showing only + +00:10:57.538 --> 00:11:00.238 +the shortest paths between peers. + +00:11:00.239 --> 00:11:06.039 +If I press Shift-s now we're looking at all paths. + +00:11:06.040 --> 00:11:10.039 +Here, we can see that in addition to going from Alice to + +00:11:10.040 --> 00:11:15.519 +Bob as a source directly, we also go from Alice to Bob through + +00:11:15.520 --> 00:11:21.079 +Eve as a source. Let's go back to showing only the shortest + +00:11:21.080 --> 00:11:27.719 +paths. Currently, the max hops for sources and for blockers + +00:11:27.720 --> 00:11:31.679 +is set to 3. Let's see what happens if we set the blockers max + +00:11:31.680 --> 00:11:33.519 +hops to 0. + +00:11:35.800 --> 00:11:39.479 +After the graph reloads, we now see that Mallory + +00:11:39.480 --> 00:11:43.286 +shows up as a source, not as a blocked source. + +00:11:43.287 --> 00:11:44.759 +This is because Bob, + +00:11:44.760 --> 00:11:49.199 +who is one hop away from Alice, is no longer included as a + +00:11:49.200 --> 00:11:52.479 +blocker, because we've set the blockers max hops to 0. And + +00:11:52.480 --> 00:11:57.519 +since Bob is not a blocker, the fact that Bob blocks Mallory + +00:11:57.520 --> 00:12:01.719 +doesn't factor in. While Alice is the only one who gets to + +00:12:01.720 --> 00:12:05.959 +decide who her direct sources, blockers, and blocked peers + +00:12:05.960 --> 00:12:10.239 +are, anyone can view Alice's peer graph, tinker with the + +00:12:10.240 --> 00:12:14.439 +sources or blockers' max hops, and use her list of sources to + +00:12:14.440 --> 00:12:19.239 +do a search. Let's see what happens if we set sources' max + +00:12:19.240 --> 00:12:24.719 +hops to 2. Well, the graph doesn't change, because we only + +00:12:24.720 --> 00:12:29.239 +ever went out 2 hops anyway. Let's set source's max hops to 1. + +00:12:30.140 --> 00:12:35.159 +Now we only see Bob and Eve, since KB3 and Mallory are + +00:12:35.160 --> 00:12:43.079 +2 hops out. Source hops 0. Now we're left with just Alice. + +00:12:44.120 --> 00:12:47.999 +Now I'd like to create a new hyperdrive and add Alice as a + +00:12:48.000 --> 00:12:52.731 +source. I'll run M-x hyperdrive new. + +00:12:52.732 --> 00:12:53.812 +Now it's prompting me + +00:12:53.813 --> 00:12:57.479 +for a new hyperdrive seed. Seed is a string of characters + +00:12:57.480 --> 00:13:01.359 +that's combined with your secret key, which is generated + +00:13:01.360 --> 00:13:04.719 +for you by the gateway program, in order to create a new + +00:13:04.720 --> 00:13:10.679 +public key for this new hyperdrive. I'll type in Joseph, a + +00:13:10.680 --> 00:13:15.319 +new drive. Now, I'll right-click on my own name, and in the + +00:13:15.320 --> 00:13:21.599 +context menu, I'll choose Set Relation From. From Joseph + +00:13:21.600 --> 00:13:32.279 +to Alice, as a source. Now, I'll right-click on my name again, + +00:13:32.280 --> 00:13:40.919 +and click on Peer Graph. Max hops, let's say three, and for + +00:13:40.920 --> 00:13:41.879 +blockers as well, + +00:13:45.440 --> 00:13:49.399 +Here's the peer graph from my newly created + +00:13:49.400 --> 00:13:54.199 +hyperdrive's perspective. Mallory is included as a + +00:13:54.200 --> 00:13:58.519 +source, three hops from the root. Let's open the list view. + +00:14:01.220 --> 00:14:06.439 +If we were to mark Alice as a blocker by clicking on this + +00:14:06.440 --> 00:14:10.319 +button in the blocker column next to the pet name for Alice, + +00:14:12.120 --> 00:14:16.959 +Then we see that Mallory shows up as a blocked source. Only + +00:14:16.960 --> 00:14:21.359 +now that Joseph includes Alice as a blocker does the fact + +00:14:21.360 --> 00:14:26.399 +that Bob blocked Mallory take effect. You can click on + +00:14:26.400 --> 00:14:30.539 +another peer to set them as the root hyperdrive. I'll click + +00:14:30.540 --> 00:14:34.999 +on Eve. Now we're looking at the peer graph from Eve's + +00:14:35.000 --> 00:14:39.519 +perspective. This peer graph view has a history. If I open + +00:14:39.520 --> 00:14:42.359 +the transient menu, you'll see here there's a back and a + +00:14:42.360 --> 00:14:47.359 +forward button. Back is bound to l for left. If I press l, + +00:14:48.440 --> 00:14:51.839 +we're looking at the graph from Joseph's perspective. If I + +00:14:51.840 --> 00:14:56.279 +press l again, now we're looking at Alice, as at the + +00:14:56.280 --> 00:15:01.439 +beginning. I'll press r to go forward, and r again, and now + +00:15:01.440 --> 00:15:04.734 +we're back at Eve. Now, I'd like to show you + +00:15:04.735 --> 00:15:08.337 +the hyperdrive-org-transclusion package we published. + +00:15:08.338 --> 00:15:10.358 +I'll open up the HyperDrive manual + +00:15:10.359 --> 00:15:14.399 +to see how to install it. + +00:15:15.680 --> 00:15:20.999 +Now, from here, I'll press m and type in transclusion to jump + +00:15:21.000 --> 00:15:23.599 +straight to the org-transclusion integration section of + +00:15:23.600 --> 00:15:27.079 +the manual. To summarize, we can install HyperDrive + +00:15:27.080 --> 00:15:30.879 +org-transclusion with M-x package-install + +00:15:32.220 --> 00:15:33.919 +hyperdrive-org-transclusion. + +00:15:37.000 --> 00:15:42.159 +Then, once this is done, we will copy the following snippet + +00:15:43.780 --> 00:15:47.559 +and add it either to our init.el file or, in this case, I'll + +00:15:47.560 --> 00:15:52.439 +just evaluate it. Now, hyperdrive-org-transclusion mode is + +00:15:52.440 --> 00:15:52.879 +enabled. + +00:15:58.100 --> 00:16:01.479 +Let's go back to the hello.org file in Alice's hyperdrive. + +00:16:01.480 --> 00:16:07.239 +I'll right-click on Alice, then click Open Hyperdrive, and + +00:16:07.240 --> 00:16:11.359 +hit Enter on hello.org. This time, I'm not prompted to mark + +00:16:11.360 --> 00:16:16.199 +Alice's hyperdrive as safe, since we did it already. I'll + +00:16:16.200 --> 00:16:20.719 +navigate to the Check Out My Peers heading. Then I'll run + +00:16:20.720 --> 00:16:28.359 +M-x org-store-link. Now, I'll create a new file in my + +00:16:28.360 --> 00:16:32.959 +hyperdrive by running M-x hyperdrive-find-file. I'll + +00:16:32.960 --> 00:16:38.488 +select my hyperdrive and I'll call this new file + +00:16:38.489 --> 00:16:45.919 +response-to-alice.org. + +00:16:45.920 --> 00:16:50.780 +Now, I'll paste in a response that I've written. + +00:16:50.781 --> 00:16:57.979 +I'll go to the bottom and I will run M-x org-insert-link + +00:16:57.980 --> 00:16:59.423 +and I'll insert the link + +00:16:59.424 --> 00:17:02.799 +that I stored earlier. As a link + +00:17:02.800 --> 00:17:07.759 +description, I'll change it to snippet from Alice's + +00:17:08.880 --> 00:17:09.879 +hyperdrive file. + +00:17:12.700 --> 00:17:18.399 +I'll save my hyperdrive file. + +00:17:18.400 --> 00:17:21.839 +Now, to show that the link works, I'll just kill this buffer + +00:17:21.840 --> 00:17:27.099 +showing the hello.org file, and I'll click on the link. + +00:17:27.100 --> 00:17:29.487 +Now in addition to linking from my file + +00:17:29.488 --> 00:17:31.488 +to the heading in Alice's file, + +00:17:31.489 --> 00:17:35.699 +I'd like to transclude this headings content in my file. + +00:17:35.700 --> 00:17:38.634 +So I'll go to the link in my file and run + +00:17:38.635 --> 00:17:45.400 +M-x org-transclusion-make-from-link + +00:17:45.401 --> 00:17:47.879 +and I'll save my file again. + +00:17:47.880 --> 00:17:50.504 +All that's been added is another link + +00:17:50.505 --> 00:17:54.433 +prefixed with this transclude keyword. + +00:17:54.434 --> 00:17:57.034 +To make the transclusion show up inline, + +00:17:57.035 --> 00:18:02.359 +I'll run M-x org-transclusion-add. The content + +00:18:02.360 --> 00:18:05.359 +of Alice's file hasn't been copied into mine. It's just + +00:18:05.360 --> 00:18:12.959 +being transcluded. If I run M-x org-transclusion-remove, + +00:18:12.960 --> 00:18:15.439 +you'll see that the underlying content is still + +00:18:15.440 --> 00:18:21.639 +just the transclude keyword and the link. + +00:18:21.640 --> 00:18:24.319 +Now some time has passed and Alice has updated her + +00:18:24.320 --> 00:18:29.879 +hyperdrive file. She wrote, please add me as a source. Since + +00:18:29.880 --> 00:18:33.559 +the transclude link that I added in my file does not specify a + +00:18:33.560 --> 00:18:36.879 +version, it will always transclude the latest version of + +00:18:36.880 --> 00:18:42.639 +Alice's hello.org file. If I run M-x org-transclusion-add + +00:18:42.640 --> 00:18:46.719 +once more, we'll see that the latest version of Alice's + +00:18:46.720 --> 00:18:51.679 +file gets transcluded into mine. Let's say that I want to + +00:18:51.680 --> 00:18:54.959 +transclude the previous version of Alice's hello.org + +00:18:54.960 --> 00:18:58.879 +file, and I don't want my transclusion to change when Alice + +00:18:58.880 --> 00:19:02.919 +updates her file. That's possible too. I'll go over to her + +00:19:02.920 --> 00:19:09.759 +file and run M-x hyperdrive-open-previous-version. Now + +00:19:09.760 --> 00:19:14.079 +when I widen the window a little, we can see in the mode line + +00:19:14.080 --> 00:19:18.279 +that this is version 57. For an explanation of what the + +00:19:18.280 --> 00:19:21.599 +version numbers mean, check out the last video or the info + +00:19:21.600 --> 00:19:25.759 +manual. For now, I'll go down to her check out my peers + +00:19:25.760 --> 00:19:32.999 +heading and run M-x org-store-link. Now, in my response to + +00:19:33.000 --> 00:19:39.159 +Alice, I'll insert the link. I'll run org transclusion make + +00:19:39.160 --> 00:19:44.759 +from link. Now there are two transclusions. The first + +00:19:44.760 --> 00:19:47.719 +transclusion will update whenever Alice updates her file, + +00:19:47.720 --> 00:19:52.919 +and the second transclusion is pinned to version 57. That + +00:19:52.920 --> 00:19:53.356 +covers Hyperdrive install, the peer graph, and + +00:19:53.357 --> 00:19:58.298 +hyperdrive-org-transclusion. + +00:19:58.299 --> 00:20:00.519 +Feel free to check out the hyperdrive.el + +00:20:00.520 --> 00:20:04.119 +info manual in the Ushin hyperdrive here, or on the + +00:20:04.120 --> 00:20:08.439 +ushin.org website. Thanks to the folks at Sopranica, we + +00:20:08.440 --> 00:20:11.879 +have a public XMPP group chat you can join, either using an + +00:20:11.880 --> 00:20:15.919 +XMPP client or anonymously from your browser. If you use + +00:20:15.920 --> 00:20:19.799 +Matrix, there's also a bridge. Thank you for watching, and + +00:20:19.800 --> 00:20:22.519 +thank you to the EmacsConf organizers and all the + +00:20:22.520 --> 00:20:25.160 +presenters who made this wonderful event possible. |
