In this talk, I am going to demonstrate a text +adventure game for learning the basics of Emacs. Through solving +puzzles and programming your companion robot, Emi, you will learn how +to use the built-in Emacs help system, the mechanic of emacs +customization and the basics of programming Emacs Lisp. I believe this +game is ideal as a light-hearted complement to the `C-h t` tutorial. + +About the speaker: + +Dr Chung-hong Chan is a senior researcher at GESIS Leibniz Institute for the Social Sciences, Germany. + +# Discussion + +- <https://github.com/chainsawriot/orgdungeon> +- Q: Maybe the Emacs tutorial could be adapted to this game flow? + - A: Unfortunately, that would be quite difficult. The Emacs tutorial is more about the basics (cursor movement, buffer management etc). And those bits are quite difficult to demo in the current text adventure format. I think a game format like vim-adventures[vim-adventures](https://vim-adventures.com/) would be better. +- Q: What was something that you learned about Org-Mode/Emacs in + working on this tutorial? + - A: ~(eval (car (read-from-string string)))~ +- Q: Could you please elaborate what's the background of this game? + What's the motivation why you choose this game as introduction for + a newbie ton enter the Emacs world? + - A: The background of this game is a bit silly. It’s actually my wife wanted to create a (general) video game last year and I told her I can create a puzzle game as well. I have no experience in programming any video game, but I enjoy playing niche video games such as Tetris and TIS-100. + I have tried to create educational material for R programmers to learn emacs, e.g. [this](https://github.com/chainsawriot/essaprimer) and [this](https://github.com/chainsawriot/presentation-typeless). Actually, the game presented so far is covering the same material of the latter tutorial. But I don’t think the written tutorial is as effective as this game. + There are so many introductory emacs tutorials. C-h t, for example, is quite good. If the path to emacs is from 0 to 100, those tutorials are good for going from 0 to maybe 20. It is nice to get the feet wet. I think that the gateway to really enjoy emacs, i.e. beyond 20, is to customize emacs so that emacs becomes your own tool. However, there is a huge perceived knowledge barrier of “learning emacs lisp” and “learning emacs internal”. From my own experience, the trick is stop “learning” (from an educational perspective, one can’t learn something for the sake of learning something.), but to “do.” The best way to immediately do something, is to play a game. +- Q: Thank you for the talk! Really cool project! How many planes are + you planning to make and what more will you teach the players? + + Q: Do you have an end goal for this game? That is, what information + do you want it to cover or will it be never ending? + - A: I am going to answer both questions jointly. The plan is to at least allow the users to write a 10-LOC function in emacs lisp. +- Q: What is plane? Is that something like a question set in the game? + - A: I am not a D&D player. But my wife told me [a Plane](https://en.wikipedia.org/wiki/Plane_(Dungeons_%26_Dragons)) is one parallel universe. But you are right, one Plane in this game is basically one question set, or one puzzle. +- Q: Is it for programmers? Non-programmers? Or general? + - A: I really hope that this is for everyone. But given the emacs userbase is like 90% programmers, I don’t mind this game is geared towards the programmer type wanting to “go beyond 20” +- Q: What is the link to your GitHub repository? + - A: It is above in the notes and links... + - <https://github.com/chainsawriot/orgdungeon> +- Q: Is `(find-file org-file-name)` [skip-to-plane] a effective + way to load information from your org-files? + - A: Probably not. The original idea was to have one giant org file and jump between headlines. But the current approach is easier to implement. +- I love this idea of using emacs to teach emacs! It is a good + continuation of C-h t. The adventure should not replace C-h t but be + its next step after finishing C-h t. Good job! +- Q: i am wondering what is the naming scheme of the planes, since there are large spaces between the numbering which i guess could be like how you leave space in between basic lines? + - A: +- with how simple the system seems it would be interesting if people forked it and add their own tutorials for their projects +- neat idea for learning about emacs! +- that was actually my first thought - it is good template for tutorial of complicated custom functions. +- Yeah, that sounds pretty interesting as an idea +- I mean, it is beautiful presentation of fun hacking, but I don't see it as real text adventure...

In this presentation, we will +demonstrate not only org-mode, but also a few companion libraries that +add functionality such as knowledge graph visualizations, literate +programming, and collaborative editing to quickly create a deeply +informative reference page. + +The starting point of our best practice is the National Research Data +Infrastructure Germany (NFDI), about which we intend to retrieve and +process certain information data gathered from wikidata. For this, we +are additionally leveraging the "org-roam" emacs package, which +provides functionality for quickly and simply linking together notes +and ideas into a custom knowledge graph. Initially, we will write a +short abstract about the NFDI and embed it into our existing knowledge +graph by linking it to other existing nodes. In the visualized graph +(using the “org-roam-ui” package), links and secondary connections to +other existing nodes can now be revealed. + +Next, we would like to enrich the text about the NFDI by with data +retrieved from the Wikidata API. A convenient way of creating +self-documenting code is the approach called “literate programming”, +which presents program logic embedded within human language text. In +Emacs we achieve this by using the “org-babel” package. Perhaps now we +find it is helpful to collaborate with a colleague in the document: +while one is writing the code, the other can explain its use and +interpret the results. We will do this simultaneously in the same +document using a method called “crdt” (conflict-free replicated data +type) and – of course – there is also an implementation of this in +Emacs. The results of the code blocks can be used for further analysis +and shared throughout the same document. + +Finally, for the sake of proper and barrier free documentation, we +show how to export the document to various formats like pdf, html, txt +etc. using either the built-in feature of org-mode or the +implementation of pandoc. + +About the speakers: + +**Jonathan Hartman** is a trained data scientist and works at the IT +Center of the RWTH Aachen University, Germany. + +**Lukas C. Bossert** is a trained classical archaeologist and is deputy +head of the department "research process and data management" at the +IT Center of the RWTH. + +Lukas, an intermediate Emacs user, is currently exploring how to +optimize his daily workflow by leveraging various Emacs packages. On +the other hand, Jonathan is a relative newcomer to this environment, +encountering common pitfalls faced by beginners.

I mean, for my personal + use case, for example, Sycnthing, sometimes it's not working + perfectly and I had to manually edit it. How is it robust compared + to syncthing? + - A (Lukas): We also faced sometimes issues that letters got + mixed up. We couldnt figure out what caused it and it was not + reproducable . I cannot compare it to syncthing, never used that + with emacs/org-mode. +- Q: How's the security for this kind of things? I mean, if we adopt + these things in our PAD, is there any, can this thing execute + arbitrary (elisp) code in different people's computer? (Think like + an adversary!) + - A: (Lukas) As far as we saw the code is executed on the local + computer, see the part with the R-code in our video. + - (zaeph) We had plans with qhong (maintainer of crdt.el) to + tunnel the connection via SSL, but we were blocked by the SSL + library that shipped with Emacs, sadly. However, we did create + a security policy that allowed restrictions on the execution of + Elisp code. (great!) +- Q: Really nice talk and demo! You guys clearly rehearsed :). I + always wonder with serial data processing sequencing like this, to + what degree do the intermediate outputs need to appear inline in the + text? Suppose you had 50,000 or one million rows from your initial + wikidata (or similar) call. How would you handle that size of data + using a collaborative, literate approach like this? + - A: (Lukas) Good question. In your local buffer there is no + difference and for the collaborative partner I cannot tell. We + testet it with 50 items because that was enough for + demonstrating our purpose. + - noweb allows getting results of evaluation without having to put + the actual data into Org buffer - just arrange the original + block generating the data to have :results silent. Basically, + :var foo=block-name does not require "block-name" to be + evaluated in advance - it will be evaluated as necessary. AFAIU, + in the talk, it is re-evaluated every time (to not have it, one + would need :cache t). + - This has tremendous utility + - So it would be stored on disk and referenced by name in a + subsequent block? Sounds useful. + - Not on disk - just cached within a single session. To store + on disk, need to save to actual file on disk. +- Q: How do you handle the viewing of larger or really any tabular + data in Emacs/Org when you want to inspect it, like the nice way + tabular data is displayed inline in Rmarkdown/RStudio? + - A: (Lukas) I have no particular way of doing this. + - What about pandas data summary functionality? Can be a simple + python block. + - Lukas: Jonathan is our python expert, he might answer this + question. + - A: (Jonathan) If I follow, you can certainly just use + DataFrame.describe() or Series.describe() to get summary + statistics for a dataset - the return value would be a Series or + a DataFrame, which would be displayed similiarly to how we show + things here. Alternatively, DataFrame.head(n) or + DataFrame.sample(n) would return a dataframe of the first n / n + random lines of a dataset, and might be a way of providing the + gist of a very large dataset without printing the entire table + in the document. + - Would be nice to have a "summarized table" functionality in + Org, that includes an abridged copy of a long table inline, but + you can open it in another buffer to browse/edit the full table + (ala block edit). + - Feel free to post a feature request - see + <https://orgmode.org/manual/Feedback.html#Feedback> +- Q: I'm thinking about an application for a single user, but in + different platforms. In a simple case. For example, you have a + buffer in your local computer, and you also want to have some files + on your pad or on your phone, and you can use this CADT concept to + make sure that there's not too much conflict in between different + editing sections. Do you think this is a good idea? I mean, compared + to purely relying on Syncthing, which sometimes I feel is unreliable + for resolving those conflicts. + - A: (Lukas) This sounds very interesting and could beneficial for + contiously working on things. + +## Notes + +- I like the way you highlight the point you are talking about in real + time. +- Conflict-free Replicated Data Types (CADT) :: + <https://github.com/emacs-straight/crdt> +- !This is the future of PAD for our conference. +- Just came here to say watching two users editing the same buffer + simultaneously is BLOWING MY MIND + - BLOWING MY MIND +2 + - blowing my mind, too ... + - WOW +- Gitlab custom-export.setup + - What about it? + - I am looking for that setup file and want to try it :) + --> + <https://git.rwth-aachen.de/dl/workshops/collaborative-coding-with-emacs/-/blob/main/emacs/custom-export.setup> + - Thank you! +- Truly one of the most impressive talks of the day.

Then only, ask for + assistance in reporting the bug we found ("M-x report-emacs-bug" + will be sufficient ) ? + - A: (Answering for Stefan, because information about how to + report Emacs bugs is widely available, including in Emacs's own + documentation: You should try to reproduce it on the latest + released version of Emacs, with a clean Emacs configuration + (i.e. "emacs -q"), before reporting. And you should look for + existing bug reports on the tracker. If you have extra time, + consider trying to reproduce it on the master branch or the + branch for the next release as well.

Maybe just post a link to your + homepage or GH repositories. + - A: It's pretty much only Org usage to document my activities in + a way that I know what I did 3 weeks ago and can pick up my + research from then. I do not use Emacs for source code review + specifically (depending on the target environment, there are + better suited tools). The thing with the field is that often, + one has to resort to work with whatever tools are at hand and to + make the most of them, which is kind of at odds with using Emacs + first and foremost as an integrated environment for everything. + Other than Org, I use it as an editor for pretty much any + programming language I encounter. +- Q: What are the biggest challenges to using transient? + - A: The documentation was very high-level compared to what I'm + used to, so I had to skim it a lot to find out how to use it for + basic tasks. I think it would be useful to have some slightly + more hands-on examples for common tasks. One issue I've run + into a few times was the code using generic functions, so it was + difficult to debug errors (like using a non-interactive lambda + form when a command was expected and getting an unhelpful error + message). + - <https://github.com/positron-solutions/transient-showcase> + might be helpful. + - Definitely, but as I've remarked in the talk, the + examples felt very "generic". Slightly more realistic + examples would make it even better. +- Q: Very cool project.

Native compilation + has brought the experience much closer to a modern app. +- Q: What do you think the future in the area of artificial + intelligence from the developer point of view? + - A: I do use xinside Emacs quite a bit when doing development in + other languages. Ex: working on ledger, haven't done a lot of + C++ lately. Ex: comparing strings only up to the length of the + shortest string. I think in terms of developer assistance, not + having to keep all the libraries in memory... Like Rosetta Code + (<https://rosettacode.org/wiki/Rosetta_Code>).

What lessons did you learn while developing + EAT? + - A:I learned how to optimize Elisp code, and also how terminals + work actually. And also process handling in Elisp. +- Q: How long did it take you to develop EAT to this point? + - A:It took around 5 months to make it working at bare minimum. + - Q: Did you have any experience with terminal emulation + before working on EAT? + - A:Not much really.

And also I wanted Eshell terminal + emulation. +- Q: Is Elisp native-compilation what allows EAT to peform as well as + or better than Vterm, or is EAT even that fast with just + byte-compilation? + - A:I use native-compilation.

At the time I implemented + the main code, I had plenty of time. I did profiling and tried + various implementations to do the same thing. +- Q: what sparked your interest in Emacs, considering its often + perceived as outdated, and how do its powerful capabilities remain + relevant today? + - A: First of all, it's free software, I have the freedom. And + the IDEs I used to use were resource hogs, so needed something + lightweight. And, after I started using Emacs, I discovered how + powerful it actually is. Emacs is itself a programming + platform, so you can make literally anything with it. +- Q: have you thought about making EAT work with shell-mode? + - A: Yes, I have considered integrating with shell-mode/Comint but + it doesn't work, they need the terminal text to be mutable and + Eat doesn't support that.

Really varies. But the number of people + with >0.2sec is significant enough to make GC a big deal. You + can check it yourself - there are GC stats plots for each + individual user in <https://zenodo.org/records/10213384>. +- Q:Having recently been working on a high-performance smooth + scrolling mode, which needs to respond to scroll events + arriving >50-60 times per second, a 100ms delay is *very* + noticeable in this scenario. For normal buffer interation and + commands 0.1s a reasonable dividing line, but I'd estimate you can + easily feel a 20ms delay during varoius "fast" interactions. Do + you think there is hope to "spread out" GC latency to keep it + below say 15ms, even if more frequent (without just repeating many + short GC's in a row)? + - A: The only reasonable "spread out" is deferring GC to + _after_ that scrolling. Like (let ((gc-cons-threshold <large + enough number to avoid multiple GCs>)) (do the scrolling)). + This is also what recommended by Emacs devs (AFAIR). +- Q:Opinions about gcmh-mode? + - A: (Not Ihor): Ironically it uses too many timers, creating + garbage of its own. It should use `timer-set-time` instead of + creating and throwing away timers after each command (via + `post-command-hook`) Interesting! + - A: (from Ihor): the problem is it ends up consuming a ton of + memory, increasing GC time, and that most GCs occur when Emacs + is being used intensively and there is no chance for Emacs to go + on idle and perform the GC. Since GC cons threshold is raised to + ~1G (gcmh-high-cons-threshold) while Emacs is used - you will + face a really bad hang (seconds to tens of seconds regularly). + Ends up not helping much, recommend increasing + gc-cons-percentage=0.2 or so instead. +- Q: + - A: +- Q: Is there some way to free up memory (such as via + `unload-feature`) in Emacs? Often I only need a package loaded for + a single task/short period but it persists in memory afterwards. + - A: <https://elpa.gnu.org/packages/memory-usage.html>, and + built-in M-x memory-report - most of the time, it is some + history/cache variables of large buffers that are occupying + memory. The library code itself is rarely affecting GC. (The + other question is when libraries add timers/heavy mode-line + constructs/post-command-hooks/etc - that's indeed a problem, + but solved by disabling or not using a package; no need to + unload) +- Q: Very nice presentation! I just experimented with the threshold + and lowered my gc-elapsed from 1.1 to 0.06 seconds (during startup). + Interestingly, going to 10MB increased the time, 4MB was the + sweet-spot for my system.

Or would cons/allocation also degrade too noticeably? + - Not the speaker: That would cause Emacs to use a lot more total memory + - Indeed. Essentially the question is at what point all my daily mostly-textual Emacs usage doesn't come close to using all the available memory on a 32G sys? (but my mind went more to being concerned about new cons/alloca and fragmentation for the intra-day use) I'll have to look into it more before being cogent. One more onto the todo list then :) + - A: for increasing thresholds up to RAM limits, do remember that individual GC time will increase - with 32Gb RAM you will likely make individual GC prohibitedly slow sooner than later. I'd say that it only makes sense to increase the thresholds when you have multiple agglomerated GCs. Going beyond this is of little use.

Emacs is a +[freedom-respecting](https://www.gnu.org/philosophy/free-software-even-more-important.html) text editor/operating system that puts you in the +driver's seat. By bringing these two worlds together, hyperdrive.el +aims to inspire deliberation about digital communication freedom. + +Hyperdrives are peer-to-peer shared folders, well-suited for data that +changes over time, like personal blogs. It complements Bittorrent and +IPFS, which work best with unchanging data, like journal archives. + +Here's a scenario: Alice creates a new hyperdrive and adds some files. +Her computer returns a public key URL that uniquely identifies the +hyperdrive. Alice shares that URL with Bob, who can then download +Alice's files directly from her computer. No third-party servers are +required to route the connection. + +Data is distributed among peers; once Bob has loaded Alice's files, +Carol can get them from Bob (or anyone else who has a copy) even when +Alice is offline. Drives are mutable; when Alice adds/removes/changes +files in the drive, Bob can refresh her drive on his machine to get +the latest changes. Drives are versioned; anyone with the URL can +"check out" prior versions of Alice's drive to see what her files used +to look like. + +Currently supported features in hyperdrive.el include: + +- [directly edit hyperdrive files](https://ushin.org/hyperdrive/hyperdrive-manual.html#Write-to-a-hyperdrive) +- [dired-like directory view](https://ushin.org/hyperdrive/hyperdrive-manual.html#Directory-view) +- [org-mode link support](https://ushin.org/hyperdrive/hyperdrive-manual.html#Org-mode-links) +- [version history navigation/diffing](https://ushin.org/hyperdrive/hyperdrive-manual.html#View-the-hyperdrive-version-history) +- [built-in bookmark.el integration](https://ushin.org/hyperdrive/hyperdrive-manual.html#Bookmark-a-hyperdrive) +- [local directory mirroring](https://ushin.org/hyperdrive/hyperdrive-manual.html#Mirror-a-whole-directory) +- [audio/video streaming](https://ushin.org/hyperdrive/hyperdrive-manual.html#Stream-audio-and-video) + +Planned features include: + +- peer discovery (swarming) +- diffing directories between versions + +Check out [the manual](https://ushin.org/hyperdrive/hyperdrive-manual.html#Installation) for installation instructions! + +You're welcome to join our public XMPP chat room! + +- xmpp:discuss@conference.ushin.org ([Join anonymously from your browser](https://anonymous.cheogram.com/discuss@conference.ushin.org)) +- #_bifrost_discuss_conference.ushin.org:aria-net.org (Matrix bridge) + +Bugs can be submitted to the [ushin issue tracker](https://todo.sr.ht/~ushin/ushin).

I enjoy fiddle, Aikido, peer-to-peer networks, +Emacs, and swimming in cold water. I work with [USHIN](https://ushin.org/), a tiny +educational US nonprofit whose mission is to promote personal, +community, and global health through free and open universal shared +information for everybody. This year, we're focusing on the +hyperdrive.el project, with the goal of bringing Emacs and +peer-to-peer together. + +I am Protesilaos. Friends call me "Prot" and you are welcome to do the +same. I have been an Emacs user for ~4 years. I use Emacs full-time for +practically every aspect of my computing. I am the author and maintainer +of several packages for Emacs and am enthusiastic about its potential +for user freedom. + +# Discussion + +## Questions and answers + +- Q: It's not clear how hyperdrive (not hyperdrive.el) works. Do I + need to install something on my computer to use it? Can I use it + from my phone? + - A: Like the emacs transmission client connects with the + transmission-daemon, hyperdrive.el connects with the + hyper-gateway daemon. + - Accessing hyperdrives on mobile: + <https://github.com/AgregoreWeb/agregore-mobile> +- Q: What lessons have you learned while developing hyperdrive.el? + - A: Great support and guidance from talented folks like Adam, + Mauve, Jonas, Prot!! +- Q: I use multiple computers and my partner also would like acess to + my notes. so 2 questions. How well would this work with using this + to editing my zettelkasten hyperdrive using multiple computers + - A: Hyperdrives are single-writer, so you'd be better off + linking between drives. In the future, we plan to add support + for <https://github.com/nobiot/org-transclusion> to + hyperdrive.el. + - Q2: How well would it work if my and my partner worked on the + same hyperdrive zettelkasten + - A: If you linked between drives, it could work quite well! +- Q: What would be a good way of getting Hyperdrives if you don't + want to install NPM and hava a binary. Could you compile it with + deno or the "rust or zig or go?" cli alternative tool? I would + prefer to download a single binary. + - A: Jonas has been using hyper-gateway installed with a `guix + shell` command. Thank you, Jonas!!! + - Quick gist: + <https://gist.github.com/tarsius/509e9c65c9df1bc243d77cd968d60daa> + - Q: <https://github.com/datrs/hypercore> rust hyperdrive? + - A: I'm not familiar with this rust port yet. +- Q: If you had your druthers, what would make your work on + hyperdrive.el easier? + - A: User feedback!! Please try it out :) +- Q: Have you tried putting a git repo in hyperdrive? Does it work + well? + - A: If you use a bare repository, take care to gc and create pack + files before mirroring to the drive, and only publish periodic + updates, then that might be okay. (And make sure not to repack + old pack files.) +- Q: Is data transferred between nodes in the clear or encrypted? + - A: Encrypted in transit. +- Q: Is there a searchable catalogue of hyperdrives? + - A: Not yet, but we have plans for a distributed "trust" + network that could be used with hyperdrive: + <https://git.sr.ht/~ushin/trust.el> +- Q: Any plans for FUSE or posix semantics? + - A: Not yet. There was + <https://github.com/andrewosh/hyperdrive-fuse> , but it's not + maintained currently. +- Q: Any plans for a TRAMP interface? + - A: Good idea! A TRAMP interface may make it easier to offer + live hyperdrive filename completions. +- Q: How does this comprare to syncthing? + - A: Syncthing is useful for sharing files among a small group of + trusted peers, like an F2F network + (<<https://en.wikipedia.org/wiki/Friend-to-friend>>). + Hyperdrives are useful for publicly sharing a set of files which + you can updated going forward and which others can link to. +- Q: If you edit a file on the hyperdrive, then edit the same file on + the local mirror. How is the conflict handled when you sync the + mirror again? + - A: If I understand correctly, you're asking about what happens + when you write to the same hyperdrive from multiple machines. + The short answer is, "Please don't do that." However, it + appears that the Holepunch team is making progress on + <https://docs.holepunch.to/building-blocks/autobase> for + "autohmatically rebasing" hyperdrive history, effectively + allowing for multi-writer hyperdrives. +- Q: wouldn't user be able to collaborate asynchronously by viewing diffs on a serially "shared" file, in other words, a user would copy another peer's text file, edit and upload their changes, share the link to their updated file so that then others can see diffs and in that way co-create an evolving file? + - A: You could try this. Another idea that we have in the works is integration with <https://github.com/nobiot/org-transclusion> + +## Notes + +- damn, I never even knew about dired-jump (C-x C-j). Main + differences with (C-x d) from the file are one fewer keystroke and + having the point on the file you came from. +- Btw, hyperdrive looks like another one of those things that would be amazing if I collaborated with anyone using emacs +- Also incidentally hyperdrive is amazing +- I installed hyperdrive.el and tried to run it and immediately got: transient-setup: Symbol’s function definition is void: transient-prefix-object + - Need to upgrade transient.el + - Gah, you are right. I had an obsolete version just hanging out causing pain. + - Okay, I got hyperdrive.el working and it was super easy. hyper://fwsn55wnznts5mpkee16j89ja38nfz6zne4wijzap1z9ka4jsxio/Dird_a333f1_4884540.jpg +- I think hyperdrive is a pretty easy way to share files. Easier than Dropbox. But maybe for delivery? I'm not sure. + - A: What do you mean by "delivery"? + - I was thinking of asset delivery. I write professionally, so I have things like PDFs and other documents to deliver. Sometimes I have big files to deliver to clients. Using something like hyperdrive would be cooler than Dropbox. ... Hmmmm, is there a hyperdrive web gateway? + - A: A good non-Emacs option is <https://github.com/AgregoreWeb/agregore-browser> Agregore is Chromium with built-in support for more protocols besides HTTP, like Hyperdrive, Bittorrent, IPFS, Gemini, and Gun. <https://github.com/RangerMauve/hyper-gateway> , the program that hyperdrive.el connects to as a client is, I think, exactly what you asking about. I don't know of a public HTTP gateway, but you could easily run hyper-gateway on a VPS. + - That would be fun. Then I could control the domain name so it would look cool and professional and like I was extra high-tech. + - A: hyper-gateway lets you serve multiple drives at various subdomains. For example, you could serve your primary drive at <https://reverik.tld>, and then folks could access, e.g., the USHIN drive at <https://aaj45d88g4eenu76rpmwzjiabsof1w8u6fufq6oogyhjk1ubygxy.reverik.tld> + + +- Great work, everyone. Thank you. +- Prot's presentations are so clear. Perfectly model pedagogy. +- Just like his code: his .el buffers SQUEAK as you C-v through them. +- Prot is indeed a model of paying attention to detail. +- I have learned so much from his videos, and from his code. +- Prot switching from vim/etc to Emacs seems to correspond to an inflexion point in the current Emacs renaissance does it not? Coincidence, or... I wonder what way the causal arrow goes :) + - I think the current "Emacs renaissance" probably dates back to around the time that package.el was developed and then when MELPA came online. momentum seems to have been building since then + - We must also consider Org-mode's inception as a key moment in recent Emacs history +- My Emacs environment would be much poorer without Prot's contributions, that's for sure. +- My hypothesis is that Diogenes himself made his way to Cyprus and spent the past immortal couple thousand years as a mountain hermit waiting to return to mortal life when the Emacs community needed him. Humor aside, there are a few key personalities---many of them here this weekend---who have been disproportionately catalytic to the community recently. Prot is certainly one.

We'll go over what LLMs are and are used for, followed by listing +the significant LLM client packages already for Emacs. That functionality +that these packages provide can be broken down into the basic features that +are provided through these packages. However, each package currently is +managing things in an uncoordinated way. Each might support different LLM +providers, or perhaps local LLMs. Those LLMs support different +functionality. Some packages directly connect to the LLM APIs, others use +popular non-Emacs packages for doing so. The LLMs themselves are evolving +rapidly. There is both a need to have some standardization so users don't +have to configure their API keys or other setup independently for each +package, but also a risk that any standardization will be premature. We +show what has been done in the area of standardization so far, and what +should happen in the future. + +About the speaker: + +Andrew Hyatt has contributed the Emacs websocket package, the triples +(making a triple-based DB library) and the ekg package (a tag-based +note-taking application).

They now also support LLama, which is hopeful + - I keep meaning to revisit the idea of the Remembrance Agent and see if it can be updated for these times (and maybe local HuggingFace embeddings) +- I think Andrew is right that Emacs is uniquely positioned, being a unified integrated interface with good universal abstractions (buffers, text manipulation, etc), and across all uses cases and notably one's Org data. Should be interesting...! +- Speaking of which, anyone trained/fined-tuned/prompted a model with their Org data yet and applied it to interesting use cases (planning/scheduling, etc) and care to comment? +- The ubiquitous integration of LLMs (multi-modal) for anything and everything in/across Emacs and Org is both 1) exciting, 2) scary. +- I could definitely use semantic search across all of my stored notes.

A "working group" / "birds of a feather" type of thing around the potential usages and integration of LLMs and other models into Emacs and Org-mode would be interesting, especially as this is what pulls people into other platforms these days. +- To that end, Andrew is right that we'll want to abstract it into the right abstractions and interfaces. And not just LLMs by vendor/models, but what comes after LLMs/GPTs in terms of approach. +- I lean toward thinking that LLMs may have some value but to me a potentially wrong result is worse than no result + - I think it would depend on the use case.

When one of my novels threatened to collapse under the weight +of its own subplots, org-mode's powerful blending of structure and prose +rescued it.

Something was missing - some +diagrams, maybe? + +The main tool for drawing diagrams in LaTeX is something called TikZ, +that is HUGE - its manual has over 1000 pages.

In particular, no one among my friends knows how styles in TikZ +really work; styles are implemented using "keys", that are hard to +inspect from a running TeX - see [1] - and I found the chapter on "key +management" in the manual very hard to understand. It feels as if +something is missing from it… some diagrams, maybe? + +In my day job I am a mathematician. I work in a federal university in +Brazil, and besides teaching I do some research - mostly in areas in +which the papers and theses have lots of diagrams, of many different +kinds, and in which people use zillions of different programs to draw +their diagrams. Every time that I see those diagrams I think "wow, I +<span class="underline">need</span> to learn how to draw diagrams like that!", but until a few +months ago this seemed to be impossible, or very hard, or very +painful… + +This presentation will be about a point in which all these ideas +intersect. I am the author of an Emacs package called eev, that +encourages using REPLs in a certain way; Lua can be used in several +different styles, and if we use it in a certain way that most people +hate - with lots of globals, and with an implementation of OO that +makes everything inspectable and modifiable - then it becomes very +REPL-friendly; there is an extension of LPeg called LPegRex ([2], +[3]), that I found promising but hard to use, so I rewrote some parts +of it to make them more REPL-friendly, and to make it print its ASTs +in 2D ASCII art. The core of my presentation will be about how I am +using REPLs written in Lua to write grammars, parsers, and tools to +generate many kinds of diagrams, and how I am using these diagrams to +document both my own code and other people's programs - the parts of +them in which some diagrams seem to be missing. My hope is that people +will find these ideas easy to port to other languages besides Lua, to +other tools for generating diagrams besides LaTeX - SVG, maybe? - and +to other ways to use REPLs in Emacs besides eev.

As we all know, Emacs is +a beast, and those who use and love Emacs spend years tweaking, adjusting, +modifying, and, above all, learning. Because at the end of the day, Emacs is a +personal journey. Everyone has preferences, searching for what makes them most +comfortable, happy, and productive. Still, I believe that we are stronger +together than we are apart. One of the best ways to find out what we like is +by seeing what other people like.

In his talk today, titled +"Sharing Emacs is Caring Emacs: Emacs Education and Why I Embraced +Video," he will share his views on communication and sharing in the +Emacs community, and how we can all do our part to spread Emacs, +support each other, and ensure its growth. +# Discussion + +## Questions and answers + +- Q: Are you using ox-reveal to make your slides?

(Two years before entering college); taking notes in + org-mode for programming classes is the BEST!!! Syntax + highlighting, inline code blocks, literate-esque programming is + great for school. Professors want PDFs on their desk! And + org-mode simplifies this process. + - Also presenter is in humanities, and writes their humanities + essays in org-mode +- Q: To Leo: Before NeoVim, you had to do as much (or more) + configuration to get basic editing done than in Emacs. It's also + slower with modal editing compared to Emacs keybindings because you + have to press Esc and two keys to get things done while in Emacs you + only have to press C/M-something (one keypress) to move or search or + whatever and then write.

Use of +Emacs was obligatory in courses covering R, Python, C/C++, SQL, and more. +Onboarding relied on simplified Emacs tutorials and starter configurations. +Sessions involved live coding, and assignments and projects required +Org-mode notebooks. I will present the setup, the results, and provide +insight into my ongoing work with Emacs in the classroom. Especially in +AI-assisted teaching, literate programming tools will become even more +important, and Emacs and Org-mode will have a new role to play. Most +importantly, using Emacs consistently for all classwork imparts deep +infrastructure and computing knowledge that other tools often obfuscate. + +- Outline (tentative): + 1.

I volunteered for that at a time when FSF was asking for one +since it was unmaintained. I did not have much elisp experience but a passion for the +package. Not much happened. + +To my great delight a few years ago the author of Hyperbole Bob Weiner joined the band and +we started together to actively develop Hyperbole again. + +One of my focus areas in that work has been to add test cases. We have now gone from no +tests to over 300 ert tests for the package. This talk is about my test case journey. What +I have learned by doing that. + + +# Discussion + +## Questions and answers + +- Q:How many tests do you have for Hyperbole and how wouild you rate + the test coverage compared to other packages? + - A: + - With all tests including the interactive we have 354 tests. + Havng said that I must point out that the size of the tests + can be very different. I tend to split tests so they are + logically (in some sense) different. So that if a test fails + it will more likely point you to what the error is. This + makes it become more tests. Codewise you could collect + similar tests to one ert-deftest making the name of the test + point out some group or collection of functions, but I + don't do that! + - I have not studied other packages so I don't know how our + test coverage compares to other packages. In fact I don't + know what code coverage we have. That is another thing to + look into. +- Q: One small suggestion, to me 'should' means optional, whereas + 'shall' or 'must' means required. Not sure if it is too late to + make a major grammar change like that :) Very nice presentation. (I + see :)) + - A: The assertions come from the ert package so any changes would + have to be suggested to that. I guess you could make your own + version of the assestions using aliases for should et al. +- Q: FYI, you may find this helpful for running Emacs tests/lints, + both from a command line and from within Emacs with a Transient + menu: <https://github.com/alphapapa/makem.sh> It also works on + remote CI. + - A: Thanks for the suggestion. I did have a look at makem.sh but + a long time ago so I don't remember why we did not try to apply + it. I might give it another look now when I have used plain ert + more. +- Q: Is it easy to run ad hoc tests inside of an Emacs session, given + the command line scripts you need to run to get a batch test session + running? In other words, can you tweak tests in an Emacs session and + run them right away? + - A: + - Yes, in principle you just load your tests and run them all + using `ert` and give it the test selector `t`. That runs + all loaded tests. + - If you want to modify a test you can do that. You change it, + evaluate it, and run it again. Just as you change any + function. +- Q: Did you have to change Hyperbole code and design to be more + readily testable as you were increasing your test coverage? + - A: + - Yes, we have done that to a small extent but we should do + more of that. Some Hyperbole functions are large and by that + complicated to test. Splitting them into smaller logical + parts can make testing easier. + - Also moving code into pure functions and avoid side effects + is a good thing. Pure functions are easier to test. Maybe + haveing the side effects separated out into fewer places. + This has not been applied but is something I have been + thinking about. With side effects I here mean things like + adding or modifying text in buffers. +- Q: What's the craziest bug you found when writing these tests? + - A: This is not a bug but I always assumed giving a prefix + argument to a cursor movement would give the same result as + hitting the key the same amount of times. So like C-u 2 C-f + would be the same as hitting the C-f key twise. It is not! When + moving over a hidden area, the three dots '...' at the end of + folded line in org-mode or outline-mode, you get different + behavior. Trying to write a test case for the kotl-mode and its + folded behavior teached me that. +- Q: Why do you prefer el-mock to mocking using cl-letf. (Question + asked in BBB) + - - With cl-letf you need to keep track if the mocked + functionality is being called or not. The el-mock package + does that for you which is what you normally want. Doing + this with cl-letf means the definition becomes longer and + more complicated. Sort of blurs the picture. el-mock is more + to the point. + - BUT since cl-letf does allow you do define a "new" + function it is more powerful and it can be the only option + in cases where el-mock is too limited. So it is good to know + of this possibility with cl-letf when el-mock does not + provide what you need. + + +[[!inline pages="internal(2023/info/test-after)" raw="yes"]] + +[[!inline pages="internal(2023/info/test-nav)" raw="yes"]] + + diff --git a/2023/talks/unentangling.md b/2023/talks/unentangling.md new file mode 100644 index 00000000..14993980 --- /dev/null +++ b/2023/talks/unentangling.md @@ -0,0 +1,166 @@ +[[!meta title="(Un)entangling projects and repos"]] +[[!meta copyright="Copyright © 2023 Alexey Bochkarev"]] +[[!inline pages="internal(2023/info/unentangling-nav)" raw="yes"]] + +<!-- Initially generated with emacsconf-publish-talk-page and then left alone for manual editing --> +<!-- You can manually edit this file to update the abstract, add links, etc. ---> + + +# (Un)entangling projects and repos +Alexey Bochkarev (he/him) - <https://www.bochkarev.io>, @bochkarev@qoto.org (Mastodon) + +[[!inline pages="internal(2023/info/unentangling-before)" raw="yes"]] + +Emacs provides a few excellent tools for working on projects through +all their key stages. Orgmode is great for brainstorming, structuring +and maintaining TODO lists, tracking time, organizing notes, and +writing memos or reports. Many major modes help writing code, magit +makes version control almost frictionless, and projectile helps with +project management and navigation. However, I found a few situations +when I wanted to separate the concepts of "project" and "source +storage" (say, having a few version control repositories associated +with a single "generalized project"). + +In this talk, I would like: + +1. to describe a specific example of such situation, + +2. discuss a workflow aimed at managing such "generalized" projects +and present my solution, based on a very simple ELisp "glue" on top of +the functionality provided by package projectile. + +For example, consider a research project (think: applied mathematics with +a heavy part of computational experiments). It might consist of: + +- The ``paper'' draft: some sort of final report source, usually in + LaTeX format, or orgmode exported to PDF via LaTeX.

Will be published along with the + paper. + +- A collection of intermediate memos (notes) sent to collaborators. + +- A collection of "raw" notes (lab journal), regarding what did I try + and especially what did NOT work and in which ways. + +This setting raises a few problems that all boil down to the necessity +of having an easily accessible private notes file(s) associated with a +few repositories at the same time outside of these repos. This way one +can: + +- Maintain more granular project structure and TODOs while still having +more concise TODO lists for the colleagues on a per-repository basis. + +- Maintain (project-specific) private technical notes, and maybe a full + lab journal both describing the "big picture" of the project and + containing the technical information. + +- Keep time tracking data private and outside of the source repositories, + +- Capture thoughts and TODOs to a single place from across a few + specific repositories. + +I propose to solve this problem by associating a single "notes folder" +and a main `.org` file to each repository using the standard mechanism +of directory-local variables on top of what is already provided by +projectile package. + + +# Discussion + +## Questions and answers + +- Q: Do you use these unentangling techniques in a blog or hosting a + zettelkasten? + - A: Well, I try to keep my "private notes" in something that + might qualify as a Zettelkasten, yes.

I tried to play around with the idea that + I structure the work in a repo, and then when I "clock in" it + saves time to a separate notes file instead... but it seemed a + little too complicated, to my taste. + - I feel that the time tracking also kind of annoying, + especially you forgot to clock on and all the things mess + up. So right now I'm just using a Pomodoro technique, 25 + minutes, done, rest, 25 minutes, rest, and kind of repeating + that. And I'm quite happy with that. + - wait, what's that? 'org-pomodoro'?. sounds + interesting... + - It's not, you know, special for Org Mode. It's + kind of a general technique which you focus on a + small task for just 25 minutes, but at the time + you're super focused, 100% focused, and after that + five minutes you rest, and you're kind of repeating + these patterns over long sections. You can do four, + five, six of those sections, and it helps me to + focus over relateive long time. + - I also feel this might be something really + useful. Just haven't found a way to incorporate + it into my workflow + - for me it's quite simple is I can just use + a simple stopwatch that every 25 minutes + stop and reminde me a rest. I believe + there's a lot of fancy clock specialized on + this this type of technique it's at the + core of this concept is really not a complex + idea. + - wait, I'm confused. So, that's outside + Emacs right? :-) + - Yes, the concept is outside of + Emacs, but I saw people using this + package. Let me search,: + <https://github.com/marcinkoziej/org-pomodoro> + <-- yeah, that one. Maybe I'll + have a look, thanks! + - Yeah, it's, again, if you're + familiar with the sports, it's + kind of making your long hard + working, breaking into a small + section, but I feel it's, you + have more kind of energy over a + long term, yeah. + - I like Using a weekly GTD log files for my TODO.

This is usually about 1000 pages. +I am not going to push my luck with a multiyear document. +Each month is a chapter. The resulting PDF is a breeze to scroll and search. +It has an autogenerated table of contents and an index. I have posted +a blank version for 2023 and another for the upcoming year +(<https://github.com/MooersLab/diary2024inLaTeX>) +One could take a similar approach in org-mode by using Bastian Bechtold's +org-journal package (<https://github.com/bastibe/org-journal>). + +I gave a 60-minute talk on this topic to the Oklahoma Data Science Workshop +2023 Nov. 16 (<https://mediasite.ouhsc.edu/Mediasite/Channel/python>). +This workshop meets once a month and is for people interested in data +science and scientific computing. You do not have to be an Oklahoma +resident to attend. Send me e-mail if you want to be added to our mailing list. + +# About the speaker: + +I am an Associate Professor of Biochemistry at the University of +Oklahoma Health Sciences Center. I use X-ray crystallography to study +the structures of RNA, proteins, and protein-drug complexes. I have +been using Python and LaTeX for a dozen years, and Jupyter Notebooks +since 2013. I have been using Emacs every day for 2.5 years. I +discovered voice computing this summer when my chronic repetitive +stress injury flared up while entering data in a spreadsheet. I +tripled my daily word count by using the speech-to-text, and I get a +kick out of running remote computers by speech-to-command. +# Discussion + +## Questions and answers + +- Q: Comment there is a text to command thing called clipea that + would be awesome <https://github.com/dave1010/clipea> + - A: <https://sourceforge.net/projects/sox/> also a good + alternative. +- Q: Could you comment on how speaking vs. typing affects your + logic/content. Thanks! + - A: I find that this is like the difference between writing your thoughts + down on a blank piece of printer paper versus paper bound with a + leather notebook. I do not think there has any real difference. I know + that some people believe there is a solid certain difference but this + is, for the purpose I am using this, for the purpose of generating the + first draft, because my skills with the-- using my voice to edit my + text is still not very well developed, I am still more efficient using + the keyboard for that stage. + + So the hardest part about + writing generally is getting the first crappy draft written. I + have found that dictation is perfectly fine for that phase. I + find it actually very conducive for just getting the text out. The + biggest problem that most of us have is applying our internal editor and + that inhibits us from generating words in a free-flowing + fashion. + + I generally do my generative writing--actually, I divide my writing + into two categories: generative writing (generating the first crappy + draft) and then rewriting. Rewriting is probably 80-90% of writing + where you can go back and rework the order of the sentences, order of + paragraphs, the order of words in a sentence and so forth. It is + really hard work that is best done later in the day when I am more + awake. I do my generative writing first thing in the morning when I am + feel horrible. That is when my internal editor is not very awake and I + can get more words out more words past that gatekeeper. I can do this + sitting down. I can do this standing up. I can do this 20 feet away + from my computer looking out the window to get my eyes a break. I find + it is just a very enjoyable to use it in this fashion. The downside is + that I wind up generating three times as much text. That makes for + three times as much work when it comes to rewriting the text, and that + means I am using the keyboard a lot and later on in the day. + + I have not made any progress on recovering from my own repetitive + stress injury. I hope that I will add the use of voice commands, + speech-to-commands, for editing the text in the future and I will + eventually give my hands more of a break. + + This allows you to actually separate those two activities not only by + time... So many professional writers will spend several hours in the + morning doing the generative part and then they will spend the rest of + the day rewriting. They have separated this to activities temporally. + What most people actually do is they they do the generative part and + then they write one sentence, and they apply that internal editor + right away because they want to write the first draft as a perfect + version, as a final draft, and that is what slows them down + dramatically. + + This also allows you to separate these two activities in terms of + modality. You are going to do the generative writing by Voice In, the + rewriting by keyboard. I think this is like what most people... One way + that many people can get into using speech-to-text in a productive way + that sounds great... + - A: (not the author, just an audiance): So, for example, when + you're talking, you have an immense feeling of the topic you + have. You can close your eyes and do your body gestures to + manipulate a concept or idea, and you have... I just feel you + feel more creative than just tapping. Definitely you have much + more speed advantage over tapping, but more important thing is + you use your body as a whole to interact with those ideas. + [this one is done via voice...] + - but typing is definitely good for acturate control, such as + M-x some-command ... +- Q: Have you tried the ChatGTP voice chat interface, if so how has + been your experience of it? As someone experienced with voice + control, interested to hear your thoughts, performance relative to + the open source tools in particular. + - A: I do not have much experience with that particular software. I have + use Whisper a little bit, and so that is related. Of course, you have + this problem of lag. I find that Whisper is good for spitting out a + sentence maybe for a docstring and a programming file. I find that it + is very prone to hallucinations. I find myself spending half my + time deleting the hallucinations, and I feel like the net gain is + diminished as a result, or there has not much of a net gain in terms of + what I am getting out of it. +- Q: Are any of these voice command/dictions freemium? + - A: To be able to add custom commands, you have to pay + $48 a year. The Talon Voice software is free and the only + limitation there is access to the language model. If you want to get + the beta version, you need to subscribe to Patreon to support the + developer. I did that, and I really did not find much of + an improvement. I really do not intend to do that in the future. + But otherwise in Talon Voice, everything is open and free. The Slack + community is incredibly welcoming. Its parallels with + the Emacs Community are pretty striking. +- Q: How good is Talon compared to whisper? + - A: With Talon, I find that the first part of the sentence will + be fairly accurate. When I am doing dictation and then towards + the end, the errors... In general, I think its error rate is + about five words out of 100 or so or will be wrong. Whisper is + wonderful because it will insert punctuation for you, but I + guess its errors are longer and that will hallucinate full + sentences for you. So they both have significant error rates. + They are just different kinds of errors. Hopefully, both over + time... [Talon] errors are generally shorter in extent. It do + not hallucinate as long. +- Q: are any of those voice command/dictation tools libre? i can not find that information on the web + - (not the speaker): + - this FAQ <https://talon.wiki/faq/> says that Talon Voice is closed source + - talon voice is non-free <https://talonvoice.com/EULA.txt> + - Mistral 7B is apache 2.0 license i.e. no restrictions + + +## Notes + +- From the speaker: I really appreciate the high level of accuracy that I am getting from +Voice In. I would use Talon Voice for dictation, but at this point, +there is a significant difference between the level of accuracy of +Voice In versus Talon Voice. It's large enough of a difference that I'll +probably use Voice In for a while until I can figure out how to get +Talon Voice to generate more accurate text. +- When you do Org mode and you have the bullets, it can allows you to naturally shard your thoughts in a way that is really easy to edit. ... It has a +summarizing capability.

The numbers don’t lie, I’m writing +more than ever, in part because of Emacs. + +In this presentation I’ll walk through my writing setup for Emacs. +I’ll go over the workflow of writing in Org Mode syntax with Denote +serving as my personal knowledge management system. + +I’ll demonstrate some of functions (or types of functions) I use for: + +- Dynamic auto-completion for Org-Mode macros +- Linking to other Org-Mode documents via different contexts (abbreviations, citations, and links) +- Different Org-Mode blocks that map to HTML elements + +And with a complete post, I’ll then walk through the resulting export. +Demonstrating the output to Hugo (and its shortcodes) as well as other +formats. + +About the speaker: + +Jeremy Friesen is a long-time software developer but only recently an +Emacs convert (as of May 2020). When he switched to writing posts +using Emacs, he observed an explosion in writing, in part because of +the joy of using a tool that he can shape and extend to meet his needs +and wants. + +# Discussion + +## Questions and answers + +- Q: Do you think the line number for writing document kind of + distraction? Especially for notes. + - A:I don't find it distracting; I've been coding for a long + time and those fringes are partially invisible. But help me + orient. + - or, what it brings to you, if we don't have that. + - Given that I'm writing code, prose, documentation, etc, + I prefer to have a common left fring...most of the time. + - Okay. I use (avy-goto-line &optional ARG) for jumping + - I bind C-j to jump to `avy-goto-char-timer`; My C-l is + bound to `consult-goto-line` +- Q: How do you manage private and public data with your zettlekasten. + One of my blockers on putting my zettlekasten on the web is I don't + want everything in it to be public. expeccily fleeting notes + - A: I explicitly export a single page at a time; this ensures the + primary page is something I consider public. + - Q: Do you have anything to prevent private links from getting + accidentally being made publicaly accessible + - The main guard is the "publish this page" function. Under + the hood, private notes are those that I don't specify a + public URL. I do this by way of the `#+ROAM_REFS:` + keyword (technically there are a few other keywords I check + as well; for bespoke historical reasons) on the document. + If it doesn't have that, then an internal link to that item + will not export a public link. +- Q: Is there anything special you're using to go from Org to Hugo + Markdown? This looks like a really nice setup, and I'd like to + give it a try! + - A: <https://github.com/jeremyf/dotemacs> you'll be looking for + jf-blogging.el (also jf-org-mode.el) +- Q: Another font question. What font were you using in eww? + - A: For fixed fonts I'm using "Iosevka Comfy Motion Fixed" and + for variable "ETBembo" +- Q: What's the story behind the name "Take On Rules"? + - A: The blog started as a game rules oriented blog; it was my + time to interrogate rule systems. But over time that drifted; + and once I moved to Org-Mode for writing I settled on an + everything and nothing blog. My + <https://takeonrules.com/about/> has a bit more details on this + - "Anything and nothing." Makes sense. :-) + +## Notes + +- <https://takeonrules.com> (presenter's personal blog) +- When you put your thoughts on the physical world, it actually helps + you to generate more.
