+- Q1: is there any additions that you have to add to emacs for using

+- Q2: One stuggle I have with this input method option is, why not use
+ an IME that\'s installed on the host OS?
+ - A:I live inside Emacs, and that the host OS typically provides

+ - A:No, everything is in pure Elisp.
+- Q4: What alternatives have you looked into for solving the problem
+ related to your markup language idea? What isn\'t achieved by them?
+ - A:The way that Emacs has evovled about properties about string
+ and text. And I suggest we adopt the \"web\" model for Emacs
+ application development. If you step back and look at where we
+ are, there\'s no such thing as no \'emacs native markup language

+- Q1: bindat seems very similar to GNU Poke (except that GNU Poke is a
+ superset, and then some, with a different syntax). I\'m wondering if
+ it might be good to add a bindat variant that translates to/from
+ Poke if need be (using libpoke), for sheer insane blazing
+ native-code JITted speed. (And, later, maybe letting bindat gain
+ some of the insanely expressive capabilities GNU Poke has got). Its
+ use of eval blocked this in times past. but now\...
+ - A:GNU Poke is indeed the natural evolution, and is much more
+ powerful.  Given the fairly little use of BinDat so far, I\'m
+ not sure there will be enough motivation to give access to GNU
+ Poke from Emacs, tho.  One of the main benefits of using GNU
+ Poke would probably be that lots of formats are already
+ available for GNU Poke, so you could directly re-use them.

+- Q1: Do you have any plans for somewhat scientific testing of colors,
+ layout, etc?
+ - A: There are already some studies on the usefulness of
+ colorization but they\'re not consistent. I would love to make a
+ study with some students but it\'s a bit beyond my expertise.
+- Q2: I have really enjoyed looking at the development of NANO emacs.
+ The only thing I slightly disagree with are the colours: on my
+ system some of them are extremely low-contrast and faded. Otherwise
+ the design is fantastic! Do you have any comments on the colour
+ scheme?
+ - A: I think you\'re right and I might need to revise the color
+ scheme, taking inspiration (or copying) some of the colors from
+ modus themes since Prot designed proper colors backed by
+ scientific theory.
+- Q3: Are your examples hand-selected from design-perspective or does
+ \"everything\" look good automatically with your setup?
+ - A: Screenshots I\'ve shown are available on GitHub and you
+ should obtain the same if you install them. Some parts come from
+ my personal configuration (org-agenda and mu4e mostly) but I can
+ post the code if you\'re interested.
+- Q4: Should we use monocromatic colour schemes over full-coloured
+ ones?
+ - A: I\'m not sure I can answer this question, I would need to
+ search if there are any recommendation on that matter.
+- Q5: Are there ways that emacs could be improved to make these kinds
+ of usability experiments easier and more accessible to users? For
+ example making it easier to switch between such experiments?
+ - A: <https://github.com/plexus/chemacs> is a perfect answer. It
+ allows you to switch from one configuration to another without
+ messing up your own.
+- Q6: Would it be possible to integrate nano emacs design to default
+ emacs design? What would the pushback be for integrating \"better\"
+ UI changes?
+ - A: I think Emacs would benefit from better defaults and I would
+ vote for modus themes to be the new default theme. Next would be
+ to package Emacs with a decent font (e.g. Julia Mono, Iosevka,
+ Inconsolata, Victor Mono) that would really help changing the
+ first impression of new users. Last would be to tweak a the
+ mode-line a bit.

+- Q1: Any plans for supporting other languages?  It\'d be great to use
+ EAF to offload processing to Common Lisp, for example.
+ - A: You\'re able to use Python & JavaScrpt/Vue to extend on top
+ of Elisp, it is so far enough (Python for Qt apps and JS for web
+ apps). Currently I don\'t see a clear advantage of using Common
+ Lisp as well, but there could definitely be a support in theory.
+- Q2: is there an eaf-app that\'s not a bootstrapping nightmare?
+ (having Vue as a dependency, eg)
+ - A: I don\'t fully understand what you mean by \"bootstrapping
+ nightmare\", all these dependencies are system dependencies that
+ you install like any other system dependency, it doesn\'t slow
+ the Emacs startup nor the system startup. But if you\'re asking
+ for an app suggestion with lightweight dependencies without JS
+ or Vue dependencies, the popular EAF Browser and EAF PDF Viewer
+ are cool app options.
+- Q3: Are there security implications to having a browser in emacs?
+ - A \[opalvaults\]: With how Emacs deals with things like
+ GPG/pass/etc. I feel like it\'s probably as secure as you make
+ it?
+ - A: \[matthewzmd\] the browser application is independent from
+ emacs itself, you\'re using a browser in emacs, but the browser
+ is not actually \*in\* emacs. The browser is QtWebEngine, a
+ modified Chromium without Google stuff, it is as safe as a
+ Chromium can be.
+- Q4: maybe i misunderstood, but is every eaf app essentially embedded
+ QT?
+ - A: yes, it\'s built upon qt-webengine 
+ - A: Yes, it uses PyQt5 and it\'s essentially painting the Qt
+ frame on top of emacs, simulating a buffer. EPC is used for
+ Elisp \<-\> Python \<-\> JS communication so that you can extend
+ Emacs in various langauges
+ - Q: I guess/hope this is using qtwebengine, not qtwebkit?
+ - A: right, qtwebengine.  If you wanna dig more into the
+ internals of EAF, I suggest you to read this part of the
+ Wiki
+ (<https://github.com/emacs-eaf/emacs-application-framework/wiki/Hacking)>
+ or my talk from last year
+ (<https://emacsconf.org/2020/talks/34/)>
+- Q5: Can the EAF dependencies be made into dynamically loadable
+ modules for Emacs, so there will be no need to rebuilt Emacs?
+ - A: There is no need to rebuilt Emacs, they\'re simply
+ dependencies that you can install using the system package
+ managers (pacman, apt, etc), npm install and pip install
+
- One thing I never tried watching all this is viewing PDF files within emacs.
- is there an eaf-app that's not a bootstrapping nightmare? I suppose having Vue as dependency makes that not so for a large number

+- Q2: AFAIK, EIEIO is generally slower than, e.g. cl-defstructs.  When

+ I don\'t think there\'s a blanket reason not to use EIEIO, but

+ - A:Not sure what further elaboration you want (e.g. \"why?\" or
+ \"when?\")
+ - I would like why? Is it just style since Emacs understand both,
+ or not?
+ - The why is to be more explicit (i.e. a form of documentation, so
+ as a reader I can see that this refers to the function rather
+ than being just a use of a symbol for other purposes)).  The
+ compiler knows about it and will hence give you a warning if you

+ - A:Good question.  We have several of them documented in the

+ you there), but that only covers those conventions with which

+- Q1: How to find a balance between «generic» molds that do not
+ provide specific enough info vs writing a new mold for every new
+ query/question?
+ - A: You can write molds that are private for your special
+ problem. I created molds for my work that I don\'t share: like
+ find the stories I am working on and how long time I spent on
+ tasks lately. Also, moldable-emacs is to make these tools easy
+ to write, so you should free to throw away tools when you need
+ them once only. If I believe a tool is a good start for many
+ other tools, I put them among the core molds, else if I use them
+ often I store them as contrib. If it is a one off, I throw it
+ away.
+- Q2: How would you evaluate this workflow for package managemnt in
+ large independent codebases. Can one integrate it with code sematic
+ analyzers to make for a better work flow?
+ - A: moldable-emacs is about creating custom tools you can apply
+ to your situation. I started experimenting with molding NPM json
+ packages + security data from OWASP to view/display security
+ issues in my packages to my colleagues in the past.
+ moldable-emacs gives me the infrastructure to answer my question
+ about security, and I now started asking myself about
+ architecture coherence, so I have scaled up tree-sitter over
+ projects to check that modules don\'t use packages from other
+ modules. By that I mean that as long as your code semantic
+ analyzers output data, you can mold that (context) data to tell
+ your story (answer the question you have). Does this answer your
+ question?
+ - You answered it very well. I am also a security auditor for
+ multiple development teams. And I am incharge of code analysis
+ in an understaffed security team. So your usecase example got my
+ usecase spot on. 
+ - Cool! For now you can define insecure patterns using tree-sitter
+ expressions (for example, I find a variable called \"password\"
+ in the code set to a string. For the package.json I linked to
+ OWASP API and looped through the packages using tree-sitter
+ tokens. I didn\'t get there, but I wanted to see an Org Mode
+ buffer with the list of the most vulnerable deps highlighted by
+ color + how to solve them: so I could pass them to developers to
+ resolve them (I am a dev, but sometimes others don\'t know about

+- Q1: Any reference to a Christopher Alexander book that you liked
+ most?

+ construction. New York: Oxford University Press.
+ - Alexander, C. (1979). The timeless way of building. New

+- Q2: You are making a great case for the ease-of-use, humanizing, and
+ empowering aspects of Emacs, but how does this align with the
+ initial difficulty for many users in learning Emacs? What is the
+ weakness of Emacs here, in relation to these design patterns?
+ - A: If we take a Vygotskyean approach to learning, we begin step
+ by step, gradually building on to what we know. What I found
+ fascinating as a non-programmer coming to Emacs was how this
+ approach works even in Emacs. Particularly if we are taking a
+ human-based approach to Emacs, it has no weakness here, because
+ humans can only move forwards from where they are, not where
+ they want to be. So Emacs becomes a good teacher in
+ process-based learning. We need to hierarchize what we know,
+ what we are ready/motivated to learn next, and also remember the
+ time required for growth.
+- Q3: How do you suggest emacs users should go about desinging their
+ work(flow) patterns?
+ - A: Strangely, I seem to have answered this above!
+- Q4: Emacs provides a lot of extensibility as mentioned in your talk.
+ This is a good thing, but such extensibility and possiblility can
+ sometimes inhibit creativity (for me at least). How could we
+ incorporate constraints in to how we use Emacs, in order to deal
+ with the possibilities that might make it\'s use more complex? A
+ great answer, thank you!
+ - A: I love this question. What about thinking about Emacs as
+ one\'s own path of desire? What do we want to do most with it?
+ But also, because Emacs is the ultimate blank canvas, in this
+ context I would recommend reading Cameron\'s \"Blasting through
+ blocks\" chapter in The Artist\'s Way to get through any related
+ anxiety and find one\'s \'creative purpose\' with Emacs. And
+ building on an answer from above, taking things one
+ project/activity/outcome at a time. Trusting that over time
+ skills and proficiency grow.
+ - I like the idea about \"Emacs as one\'s own path of
+ desire\". It\'s all in my init.el.
+ - Emacs is seriously the best in this respect!  :) And it is
+ so great to be part of this conference to be among like
+ minds!:)
+- Q5:In your opinion, what approaches might be tried to introduce
+ individuals to these aspects of emacs\'s user experience? In my
+ experience, many of my co-workers are often impressed with what I am
+ able to do with emacs, but they remain reticent to attempt it
+ because I find it difficult to produce a suitably encapsulating
+ \"elevator pitch\" for it.
+ - A: Not everyone wants to think about the tools that they use.
+ Haha, that is why I am trying to get one convert at a time, and
+ let them convert others in their midst :)
+- Q6: Are there ways to reach out to you after the conference to dig
+ deeper here?
+ - A: gretzuni.com
+- Q7:On the mention of emacs being \'frontierless\': Doesn\'t this
+ result in a kind of \'characterless\' or \'non-definied\' space? For
+ example, if I learn a musical instrument, I am bound by various
+ frontiers/horizons (12 tone system, the tamber of the particular
+ instrument, etc). Surely there are similar limits on the
+ extensibility of emacs and the possibilities it offers for \'human
+ expansion\'. If so, which limits/boundaries of emacs do you see as
+ most meaningful/impactful on growth and transformation?
+ - A: That is a really interesting question. Aren\'t the limits
+ here our knowledge? I am really stuck on the idea of Lisp and
+ its dialects as being particularly philosophical. Any time I
+ look at what people do with Lisp it seems to be profoundly
+ related to design on a deeper level. I will leave it here for
+ now - but thank you for the question, I will be sure to mull it
+ over and possibly blog about it at some point\...
+ - Hi! Thank you for the answer, that was exactly what I was
+ thinking about (elisp being something particular/defining to the
+ emacs experienc/environment). I don\'t know lisp/programming
+ myself, so I was just interested in your perpsective! Really
+ loved the talk a lot! But the way, the question came from a
+ hermeneutic perspective, where boundaries/horizons are essential
+ for defining/demarcating the self (of course, within a boundary
+ there can be endless play, but the limits set the \'rules\' for
+ play, and therefore create meaning).Thanks again!
+ - Wow - a fellow hermeneuticist?! 
+ - Haha, yes. In my past life I studied it ;) also studied a lot of
+ Stiegler too, so was interested to find him in the talk!
+ - That is quite uncanny! The combination of the three (plus Emacs)
+ have given me a whole new perspective on life - and I wonder why
+ Stiegler didn\'t pursue Free Software more, though he does nod
+ to it here and there. Do you have any work to share, would you
+ like to keep in touch?
+ - sure! would be great! :) My main area was Ricoeur, so I have
+ written some things on Ricoeur and technology (there was a
+ recent volume on his work, and I wrote something on
+ postphenomenology and ricoeur) I\'ve since left academia though,
+ because it was quite difficult to find full-time work
+ (especially since hermeneutics is so
+ underappreciated/underreppresented! so, I always get excited to
+ hear others talking about it ;)
+ - Yes, I know what you are talking about and actually the whole
+ future - and present - of academe is an interesting question -
+ haha that I think is related to Emacs, I mean, we do live in the
+ knowledge age so we need tools to help with this. Ricoeur has a
+ great essay on ideology and science critique, which is so limber
+ (as opposed to so much calcified academic thinking) and I am so
+ interested in exploring approaches to academe that \'continue
+ the ongoing work of the hermeneuticist\' (I am paraphrasing him
+ here) that make use of technology, possibly through something
+ like Ted Nelson had in mind, where we literally trace the traces
+ among ideas\... wow, that\'s a mouthful of a comment. Ha! I am
+ overjoyed at the opportunity for this conversation, thank you so
+ much! :) 
+ - really interesting that you are referencing Ted Nelson in
+ this context. I think org-roam, in many ways, resembles what
+ he had in mind with Xandadu; well, with the limitation that
+ org-roam only serves Personal Information Management, not
+ our civilisations\' as he intended with Xanadu.
+ - Yes! the feeling is mutual :) I really love Ricoeur\'s general
+ style and approach to questions. Unfortunately he didn\'t write
+ much about technology itself, which made my job quite difficult!
+ But I did meet a friend of his once that told me that, in the
+ 70s, Ricouer had asked him \"are we still writing when we use
+ computers?\". So, he was thinking about the question at least. I
+ only discovered emacs after I finished all that word, but since
+ then I can finally say that \'yes!\' we can \'write\' using
+ computers (with writing being a core activity of the self for
+ Ricoeur). Also, I just wish I had emacs instead of just writing
+ so many academic papers in microsoft word! 
+ - Ha! Yes, the moment of being freed from that software box and
+ having all the LaTeX options in Emacs (here, I list my fave) is
+ like stepping into technicolor out of black and white - to this
+ day, I still feel that way! So much you wrote is interesting.
+ Stiegler\'s concern of whether technology - like the writing pad
+ in Plato earlier - would strip us of our intellectual capacity
+ (I can see that possibly happening with automaticizing tools
+ like - maybe Excel is a good example, because one does not
+ really have to think about what one is doing). But Emacs use
+ prompts us to ask questions and design \*exactly\* what we are
+ looking for.
+ - wow, yes, that is so interesting. I never considered the
+ question of desire and emacs until your talk, and it was
+ definitely one of the most interesting parts!
+ -  In my work I was also mostly interested in Freud (the role of
+ \'technique\' in psychoanalysis) and also Foucault\'s later
+ lectures on hermeneutics of the self/technologies of the self.
+ The angle of \'desire\' in relation to personal
+ configuration/design was so interesting to me and like an
+ \'aha\' moment. I\'ll definitely be thinking about it more!
+ Thank you so much again for the talk and all the responses!
+ - Thank you too, and hope we\'ll be in touch!
+ - Yes :) enjoy the rest of the conference!
+ - Likewise :)
+- Q8: What was that Crichton quote? That was neat! (From the
+ references - Crichton, M. (1983). *Electronic life*. New York:
+ Knopf.)
+ - A: Thank you - I hope that general computing will have its day!

+ publications or other good references on this topic that you can
+ share/link here?

- Andrew Blinn's talk on Fructure and Ethan Leba's talk on Tree-edit are really insightful.
- Agreed about the lack of formal grammar (only a proliferation of parsers) being a limiting factor. Maybe we could bridge directly to the available commands without going through a grammar though.

+- Q1: A common issue I have with Magit status buffers is that focus

+ - A: It is certainly possible and compatible.

+ thousands of elements (and thank you for your work on this, it\'s
+ very exciting for Emacs\'s future)
+ - A: In general EWOC and tabulated-list should perform better, and
+ tui still needs some optimization. TUI has the potential to be
+ better, but it needs some work.
+- Q6: Are you planning to contribute tui.el to emacs core?
+ - A: Eventually, once its polished and more robust.
+- Q7: What is the memory overhead like, e.g. I guess values are hashed
+ to detect whether items need to be re-rendered?

- like in dogears.el readme
- So I'm really interested in potentially using tui for Ement.el
-- there are 2 or 3 ways I could imagine using it...
- 1. For the room buffers, showing events in the chat rooms. That sometimes has thousands of events, so that's why I asked about performance for that case.
- It seems like it could be very helpful for re-rendering some events when their content changes, e.g. when messages are edited, when coalescing adjacent join/leave events...
-- That sounds interesting. I don't know anything about React
- EWOC does work for that to some extent, but I've been unable to get nested EWOCs to work correctly so far, so TUI is an interesting alternative
-- yes IIRC
- yeah, EWOC uses markers too AFAIK, and it seems to perform well enough even with 2000-3000 events in a buffer
- oh yeah, your grid idea
-- that would be SO useful
- yes, sorting and filtering, temporarily hiding elements!
-- that would be SO useful
- like "show all messages from this user or mentioning that user in this room"
- and then press a key and all the others are shown again
-- ahh, I need that! :)
- expanding larger images from thumbnails, captions for files, etc
- like Element.io but in Emacs with TUI, that would be great
- that's the official Matrix Web client
-- I think it uses React
-- but I'm not sure
- Sounds great! well thanks for the presentation, I really look forward to TUI's progress! maybe someday I can help with it, in the distant future... I have too many Emacs projects already :)
- hmm, a TUI library for taxy.el... more ideas!
- TUI would be like a natural frontend for taxy.el as a backend
-- that would be fun :)
- are you on Matrix by any chance?
-- maybe someday, need to get more people "jacked in" :)
- I'm bad with email, but when I have time to check out TUI in more detail, I look forward to it!
