Try it! (No prerequisites)

% (find-2024gitvideo "08:06" "thing these bullets here behave in")
% (find-2024gitvideo "08:09" "exactly the same way as the red stars, so")
% (find-2024gitvideo "08:13" "if I type f8 here three times it creates")

% (find-2024gitvideo "19:33" "and the idea is that a")
% (find-2024gitvideo "19:36" "command like this one, Time 4:20, in a")
% (find-2024gitvideo "19:40" "script means \"it's 4:20 now\", or \"at this")

% (find-2024gitvideo "20:10" "so, in this test here I will run")

% (find-2024gitvideo "20:21" "created this tree here...")

% (find-2024gitvideo "20:26" "but now my new version of that...")

% (find-2024gitvideo "20:35" "versions side to side...")

% (find-2024gitvideo "20:39" "the new version has more columns,")

% (find-2024gitvideo "20:46" "for example, this point here is")
% (find-2024gitvideo "20:48" "going to be the timestamp A0, this is the")
% (find-2024gitvideo "20:51" "timestamp A1, timestamp A2, and so on...")

% (find-2024gitvideo "20:57" "so each one of these things takes a")
% (find-2024gitvideo "20:59" "low resolution picture of the repository")
% (find-2024gitvideo "21:01" "at that point... the low resolution picture")
% (find-2024gitvideo "21:03" "is just a tree")
% (find-2024gitvideo "21:04" "generated by git log...")

% (find-2024gitvideo "21:09" "and all these low resolution")
% (find-2024gitvideo "21:12" "pictures are saved to files with certain")
% (find-2024gitvideo "21:14" "names, and then at the end I can run")
% (find-2024gitvideo "21:17" "this thing here,")
% (find-2024gitvideo "21:19" "Timeline, that concatenates all these")
% (find-2024gitvideo "21:23" "files... so let's run that...")

% (find-2024gitvideo "21:30" "now if I run Timeline it generates")
% (find-2024gitvideo "21:33" "all these trees here, and this line here")
% (find-2024gitvideo "21:38" "does the same thing, but it")
% (find-2024gitvideo "21:41" "also generates a file called /tmp/all.")

% (find-2024gitvideo "21:50" "Now that we have that file we")

% (find-2024gitvideo "22:15" "I found the rules very hard to")
% (find-2024gitvideo "22:18" "understand... I mean, when I was")
% (find-2024gitvideo "22:23" "able to draw the diagram then things")
% (find-2024gitvideo "22:25" "became much simpler, but just by")
% (find-2024gitvideo "22:28" "reading the rules and the manuals I")
% (find-2024gitvideo "22:30" "found them very complex, but... so, when I")
% (find-2024gitvideo "22:35" "started studying this diagram here the")
% (find-2024gitvideo "22:38" "the rules started to become clear to me,")
% (find-2024gitvideo "22:41" "and when I found a way to translate that")
% (find-2024gitvideo "22:43" "diagram to the other format, that is")
% (find-2024gitvideo "22:46" "much prettier, then things become much")
% (find-2024gitvideo "22:50" "clearer. So these diagrams helped me a lot.")

% (find-2024gitvideo "22:58" "So, this section here is about how to")

% (find-2024gitvideo "23:04" "the files that were created... note that")

% (find-2024gitvideo "23:38" "this eepitch block here creates a very")

% (find-2024gitvideo "24:08" "And if we run magit on that repository...")

% (find-2024gitvideo "24:11" "by the way, if you do not have")

% (find-2024gitvideo "24:19" "use this thing here and install it in")
% (find-2024gitvideo "24:22" "the eev way... you may need this thing here")
% (find-2024gitvideo "24:27" "to configure MELPA,")
% (find-2024gitvideo "24:30" "like running this and this...")
% (find-2024gitvideo "24:35" "and then you can execute these")

% (find-2024gitvideo "24:42" "package-refresh-contents and package-install,")
% (find-2024gitvideo "24:44" "and then you will have magit in")

% (find-2024gitvideo "24:48" "Anyway, I do have magit here.")

% (find-2024gitvideo "24:52" "Let me run this thing here... it runs magit")

% (find-2024gitvideo "26:09" "I did that from magit, and it should be")

% (find-2024gitvideo "26:37" "magit... this is the part that")

% (find-2024gitvideo "26:47" "part that explains how to create new")
% (find-2024gitvideo "26:50" "commits... and again, I found these things")
% (find-2024gitvideo "26:53" "very hard to understand when I")
% (find-2024gitvideo "26:56" "started to learn magit...")

% (find-2024gitvideo "27:00" "and now here we have a section about")
% (find-2024gitvideo "27:02" "\"Why this?\", and about... anyway, let me")
% (find-2024gitvideo "27:07" "read this. I found git and magit both very")
% (find-2024gitvideo "27:11" "hard to learn. To test most concepts we")
% (find-2024gitvideo "27:14" "would need a repository with tags and")
% (find-2024gitvideo "27:16" "branches, and a second repository that")
% (find-2024gitvideo "27:18" "pulls from that...and even with that")
% (find-2024gitvideo "27:21" "most tests would be very hard to undo")
% (find-2024gitvideo "27:24" "and to reproduce...")

% (find-2024gitvideo "27:26" "and when I was trying to learn git...")
% (find-2024gitvideo "27:29" "more specifically, I was learning git")
% (find-2024gitvideo "27:32" "to set up a git repository")
% (find-2024gitvideo "27:35" "for eev, my package...")

% (find-2024gitvideo "27:39" "When I was trying to set up a git")
% (find-2024gitvideo "27:42" "repository for eev on GitHub for the")
% (find-2024gitvideo "27:44" "first time I did several things wrong on")
% (find-2024gitvideo "27:47" "the GitHub side, and I didn't know how to")
% (find-2024gitvideo "27:50" "fix that... I didn't know how to undo these")
% (find-2024gitvideo "27:53" "things... and after spending several")
% (find-2024gitvideo "27:56" "days trying to fix that I gave up, I")
% (find-2024gitvideo "27:59" "deleted that repository, I created a new")
% (find-2024gitvideo "28:02" "one, and I decided that I would be very")
% (find-2024gitvideo "28:05" "coward from that point on, because I")
% (find-2024gitvideo "28:08" "didn't know how to undo certain things...")
% (find-2024gitvideo "28:11" "and I decided I would always do lots")
% (find-2024gitvideo "28:14" "of local tests before messing up my")
% (find-2024gitvideo "28:16" "public repository again.")

% (find-2024gitvideo "28:19" "So at that point I started playing")
% (find-2024gitvideo "28:22" "with the idea of reproducible tests and")
% (find-2024gitvideo "28:26" "not committing everything to a")
% (find-2024gitvideo "28:29" "repository in GitHub, and this is my n-th")
% (find-2024gitvideo "28:31" "version of my tools for doing lots of")
% (find-2024gitvideo "28:34" "local tests. And, of course,")
% (find-2024gitvideo "28:35" "if you like this approach")
% (find-2024gitvideo "28:38" "then please get in contact!")

% (find-2024gitvideo "28:43" "Let me show another example of")
% (find-2024gitvideo "28:46" "something that the tutorials suppose")
% (find-2024gitvideo "28:52" "that... no, sorry, let me explain it")
% (find-2024gitvideo "28:55" "in another way. A typical use")
% (find-2024gitvideo "28:58" "case for git is like this: there's a")
% (find-2024gitvideo "29:00" "\"shared\" git repository in a \"server\",")
% (find-2024gitvideo "29:03" "and there are several \"developers\",")

% (find-2024gitvideo "29:07" "machine, and the developers are working")
% (find-2024gitvideo "29:09" "on copies of that shared repository, and")
% (find-2024gitvideo "29:12" "they are making changes on that and they are")
% (find-2024gitvideo "29:15" "trying to somehow synchronize their work.")

% (find-2024gitvideo "29:17" "So they are going to save")
% (find-2024gitvideo "29:20" "their changes to their local repositories,")

% (find-2024gitvideo "29:23" "changes to the \"server\" somehow...")

% (find-2024gitvideo "29:29" "and I found that the")
% (find-2024gitvideo "29:33" "tutorials suppose that you are one")
% (find-2024gitvideo "29:36" "of the developers, and that you are")
% (find-2024gitvideo "29:38" "working with colleagues on that shared")

% (find-2024gitvideo "31:39" "switch to this directory here instead of")
% (find-2024gitvideo "31:41" "switching machines... and we run git pull.")

% (find-2024gitvideo "31:45" "So this is a miniature that")

% (find-2024gitvideo "32:41" "repository... preferably in a way in")
% (find-2024gitvideo "32:44" "which this creation mechanism is easy to")
% (find-2024gitvideo "32:48" "run again...")

% (find-2024gitvideo "32:50" "and then we have to teach people")
% (find-2024gitvideo "32:54" "what are the keys that they have to")
% (find-2024gitvideo "32:55" "press in magit... for example")
% (find-2024gitvideo "32:58" "here for staging the changes people")
% (find-2024gitvideo "33:02" "have to to press S in a certain part of")
% (find-2024gitvideo "33:05" "the magit buffer, and then they have to")
% (find-2024gitvideo "33:08" "type \"c c\" in another position of")
% (find-2024gitvideo "33:13" "the magit buffer... so it's a totally")

% (find-2024gitvideo "33:18" "So: this is a prototype, but")

% (find-2024gitvideo "33:26" "please get in contact!")

% (find-2024gitvideo "33:28" "And... that's it! That's what we have")
