Bob,
I tried your JHS lab on Linux. It worked on Centos and failed on Ubuntu:
Chapter: Action of {. on Non-Empty arrays
*** event handler error
ev_dot_ctrl 0

jtype ctrl

Hi everybody,
With the help of Chris I have updated the Head Monadic Verb lab so that it runs
in both JHS and jqt in j901. You will need to update your addons suing either
the package manager or JAL, but when that is done you should be able to run the
labs with videos. Again, this is for j901 only.
Enjoy.
Cheers, bob

Hi everyone.
I have repurposed the Head video into a lab for the JHS environment. To access
it you will need to update your applications using jal in the IDE menu,
specifically the lab files.
Then you should see 'Video - The Head Monadic Verb - {.y' within the core group
of labs. Listed alphabetically, it is at the bottom of the list.
If you have connectivity to youtube.com you can run the lab and the videos will
display. Without connectivity, the lab will still run, but videos will not
display.
Have a look and see what you think.
It is early days, but I think this has potential and the addition of
interaction with the JHS environment changes the feel of the presentation quite
a bit.
Cheers, bob

Thank you Ian,
You have given me several good ideas that could benefit from video explanation.
I agree that the Head example is probably not the one that is best suited
to video. For me, it was a chance to dip my toe in the water and see how it
might work. The more conceptual ideas, such as Henry's diagrams comparing the
different
composition conjunctions, could be fertile ground for video explanation.
One of the other ways that I think that the Head video may work is to wrap a
lab around it. In the next couple of days I am looking to release a video lab
based on the
Head video in JHS. I think that this increases the usefulness for teaching
purposes and may be
a potential use for some of the simpler videos. I look forward for your
reflections on
this project.
Also, thank you for the comparison with 3Blue!Brown, but Grant Sanderson's
videos are
ones that I aspire to and are beyond comparison to my current level.
Thanks again for your valuable input.
Cheers, bob

Your videos are gorgeous, Bob. A 3Blue1Brown channel for the J community.

As I said I think that I am looking for a use for my tools more than
anything else.
Your "Items" movie aptly meets a training need. It also fills a blind-spot
in NuVoc ??? as it's presently conceived. More so than your Head ({.) movie
and its proposed series. That is, considered as a proof of concept, rather
than a work of art, where it can't be faulted.
I didn't think there was a lot of future in the idea of a Head-type movie
for each of the 121 primitives documented by NuVoc. The idea's come up
before, and I haven't changed my mind about it. It's a helluva lot of work,
fated to be mostly wasted.
Here's why.
Originally NuVoc aimed to deliver online help at the point-of-use in the
shortest possible time, with minimum demands on the beginner's overloaded
brain. It avoided diverting the user's attention from the coding task in
hand, i.e. their own, whatever it was. It assumed he or she had no time
(???just then) to settle down to a sublime exposition of J theology. That's
why there's a line across the page (originally a heavy line!) with "More
Information" below the line.
I fear your Head ({.) movie and its kin would go below the line, in amongst
"More Information". This would condemn it and its siblings to being watched
perhaps twice or 3 times in the whole career of any given novice user, and
then for perhaps just 2 or 3 primitives. Your "Items" movie escapes my
criticism by being both more general and much better targeted.
Let me suggest what these "2 or 3 primitives" are: Rank ("), Cut (;.),
Atop (@) &co.
They're all conjunctions. Precisely where NuVoc meets its greatest
challenge (???and fails, some would say). NuVoc does best when it deals
separately with verbs and adverbs derived from conjunctions. IMO here's
where your videos would really show-off their power.
Example:
Buried in the "More Information" section of Atop (@)
https://code.jsoftware.com/wiki/Vocabulary/at ???you see a marvellous diagram
(due to Henry) of what verb composition is all about. I used to study this
thing like a mandala. But might it be better as a movie? Or supported by a
movie?

well done. I thought this concept was getting through just fine in your
{. video, but this is a concise and direct addressing of items.

As a reply to Raul, I have created a video that explains the concepts of
items in J. This is a bit different as it deals with a concept rather than
a verb.

Let me know what you think.
