 liked a lot for exploratory analysis. In this talk, I will show how to add
 similar reactivity in Org-Babel.
 
+## Discussion / notes
 
+-   Q: Is there a web page describing this topic?
+    -   A: The repository readme is here
+        [https://dev.lepisma.xyz/git/ob-rx/](https://dev.lepisma.xyz/git/ob-rx/){rel="noreferrer noopener"}
+        but not sure if you meant any other kind of description.
+-   Q: If I understand correctly, recomputation happens upon saving; why
+    not tie it to C-c C-c instead?
+    -   A: You can tie the (interactive) function it to C-c C-c too, I
+        usually prefer on-save reactivity when I need reactivity.
+-   Q: You mentioned that you are working on something similar for
+    JS\... what do you have now? (Thanks! =))
+    -   A: I don't have something public but I am using a webkit child
+        frame to show up d3 plots. Will add this in ob-rx once I have it
+        stable.
+-   Q: If this could work on C-c C-c and as a minor mode, then it could
+    perhaps be contributed upstream!  Is that planned?
+    -   A: Not thought about it, maybe.
+-   Q:Is it possible to do something reactive with :result file :file
+    my-generated.file (?) - yes you got it, it's just I make
+    intermediate compilation steps in org sometimes using that.
+    -   A: Yes, the core mechanism is to just control the order of
+        execution for code blocks. So any normal workflow involving
+        files will also work. I have tried a few file workflows and
+        ended up needing ob-async so that Emacs doesn't get stuck. But
+        I am not sure if I understood your exact use case (?).
+-   Q:how does it handle circular dependencies?
+    -   A: I haven't checked if my approach gets stuck in circular
+        dependencies (it should), but usually when I am writing
+        org-babel notebooks, I end up not having circular dependencies.
+        The check for this should be easy enough though and the
+        minor-mode could warn if it detects a circular dep. Will add
+        this in later versions.
+-   Q: How to get the block dependence plot? Very nice.
+    -   It's a small piece of graphviz code in the minor mode, here
+        [https://git.sr.ht/\~lepisma/ob-rx/tree/master/item/ob-rx.el#L118](https://git.sr.ht/~lepisma/ob-rx/tree/master/item/ob-rx.el#L118){rel="noreferrer noopener"}
+        -   Thank you.
+-   Q: I'm curious what packages you're using for org appeance. It
+    looks like a mix of org-modern and some other packages. (Yes I am
+    also interested in your overall emacs theme)
+    -   A: So my config is here
+        [https://git.sr.ht/\~lepisma/rogue/tree](https://git.sr.ht/~lepisma/rogue/tree){rel="noreferrer noopener"}
+        but maybe the core part of the look is based on my older blog
+
+
+
+
+-   I'm really looking forward to this talk.
+-   Excited to see reactivity in org-babel!
+-   Your emacs theme is very pleasing!!
+-   I will try this type of dependence block. It looks like it can save
+    a lots of mental effort to organize my data.
+-   Excellent talk!

+-   Cool project!
+-   Great talk and beautiful Emacs!
+-   This seems to add useful features to org-babel, great job!
+- Very cool!
+- Very interesting !
+- https://dev.lepisma.xyz/git/ob-rx/
+- this looks useful.
+- I'm quite fond of Pluto.jl in Julia, so it'd be nice to have something like this that I can use from inside Emacs.
+  - Yeah, it also reminded me of Pluto
+  - But I really prefer working from inside Emacs, so I don't use Pluto that much. This is great
+  - It could hopefully minimize my usage of rstudio
+  - I was thinking something like that too for the R folk
+  - Indeed, rstudio is nice, but it is not emacs
+- excellent talk by tushar
