notebook VS JRuby

For folks asking what the Notebook UX offers that the Lab does not, this github thread may be enlightening: https://github.com/jupyter/notebook/issues/6210

(TLDR: some novice users in educational settings find the lab environment overwhelming.)

For further info refer to the official GitHub Repo.

DisabledFunctionError: cv2.imshow() is disabled in Colab, because it causes Jupyter sessions to crash; see https://github.com/jupyter/notebook/issues/3935. As a substitution, consider using from google.colab.patches import cv2_imshow

As it seems, this is not quite straight forward and manyusers have similar troubles.

As someone who has looked at Shoes several times but never dove in, it's confusing how Shoes 4 has been the "preview version" of Shoes for, like, a decade or more. It made me actively avoid getting invested in Shoes 3 (the release promoted on the linked website) because Shoes 4 requires JRuby and I am happy with CRuby (the Ruby interpreter most people think of when they hear "Ruby").

No disrespect to the developers but to me it feels like taking over a GUI toolkit created "to teach programming to everyone" (to quote the Shoes 4 readme) and making it depend upon a super-complicated enterprise-focused Ruby was sort of Missing The Point™ in a huge way.

Heck I couldn't even switch to JRuby if I wanted to because I <3 Ractors and JRuby still lacks CRuby 3.0 feature parity: https://github.com/jruby/jruby/issues/7459

__callee__ now properly returns the name under which a method was called, which will be the new name in the case of aliased methods. #2305, #7702

rdoc has been updated to 6.3.3 to fix all known CVEs. (#7396, #7404)

Altering the visibility of an included module method no longer changes what super method gets called. (#7240, #7343, #7344, #7356)

It looks like the readme is copy pasta from jruby: https://github.com/jruby/jruby

Chris: Yeah, that's exactly right. So I was working at Sun at the time. I remember the JRuby guys. I saw them speak at one of the Java conferences, and they came to work for Sun. Just listening to them talk about JRuby...and then a lot of it was obviously about Ruby on Rails at the time. And I was like, wow, this was just mind-blowing the way they talked about it.

In fact, I built its GUI twice with two different approaches, one using the up and coming Glimmer DSL for LibUI on CRuby relying on a multi-canvas-grid (LibUI area) approach, and one using the very mature Glimmer DSL for SWT on JRuby by relying on a button-grid approach.
