Yes, but only up to a point. Wall-to-wall talking heads and vaguely
relevant wallpaper is boring. Veritasium seems to have the right mix, at
least with his earlier videos. Though I'm thinking of a lot less
talk-into-camera. Voice-over with a live session is better (if no fumbles).
Ex-IBM Human Factors, my guiding star has been: spoonfeed the new user. But
a meaty masterclass on (say) debugging may fire-up a J newcomer if it's not
couched in J-speak or somehow else mystified.They may not follow the detail
without doing some homework, but be impressed with how much easier it is
than they're used to.
*Masterclass topics*
J best-practice.
J tools to make life easier for the jobbing programmer, the use of which
may not be obvious to a beginner. Or tools which suit a particular sort of
workflow or problem-solving approach, which even a J journeyman might not
know about.
The sort of things that are *not* to be found in the programming forum or
NuVoc, but more like a chapter from 50 Shades Of J, or At Play With J.
Making a video from a APWJ chapter might be a good example to start with,
since the script is almost written for you.
*Topics on my own to-do list*
to write articles about:
Debugging
using (13!:) versus Run > debug…
Avoiding use of debug at all via line-by-line re-execution in the session
manager, having assigned (y=:…) and (x=:…) .
stdlib gems
ignoring verbs that a C++ programmer would expect to be there, or verbs
like mean or avg, which are flaunted for their gee-whizz value.
string handling
Not just { {. {: but stdlib tools like rplc, (;:), taketo, regex.
Handling unicode.
Understanding someone else's tacit expression, e.g. examples from _z_
locale or addons.
Use of (13 :), addon: tte, dissect.
Reducing to a train and dividing into triples.
In fact *dissect* merits a whole masterclass to itself.
It's something I've never got on top of (having long fossilized my J usage
and so never felt the need for).
Rank
how it makes functional composition far easier to code than does APL
why J needs so many confusing conjunctions and constructs for function
composition: Atop (@), At (@:), Compose (&), Appose (&:), Hook ((u v)),
Fork ((f g h)) (…actually it doesn't.)
A bit of history as to how it all arose.
why ("0), ("1), ("_) covers 99% of what you'll ever need.
Which to do first? That's hard to answer.
++ Whichever's the biggest use to an intermediate J-er
++ Whichever best exemplifies what we're trying to achieve
++ Whichever appeals most to you.
