Some "Polyglot" toughts on "topic demos" and/or the show-case
I'd like to see at least one "topic example", written in something
else than Java(EE). This makes it easier for us promoting the mobile
libraries to native iOS developers (or JS guys), since a JavaEE based
backend is not something they would prefer using (most of them).
For us the point is really "promoting" our MOBILE efforts, and we know
our mobile lib's don't care about the backends. (E.g. take the
integration tests we have for Android, iOS or JS - they go against
Reddit or Github API - we have no clue (perhaps a guess) what they use
for implementing these "services")
Ok, now this ProDoctor is based on Forge/JavaEE, which is fine with
me, since that's IMO the classical JBoss target. Also, if I understood
Luke's comments from Summit, these guys
are looking into "mobile" (Android, JS, iOS), so that's a good spot for
them.
However, the other platforms are also important (especially when
talking to JS/iOS hackers).
I'd say, yes - why not build another topic-example, based on a
different "backend technology".
I'd prefer Node.js over Ruby/Sinatra... (I can't read Clojure, so I am
not proposing that :-))
I mean another topic demo, not a rewrite (aka "ProDoctor.js" ;-))
Or maybe even the "Show-Case" in some other language??
Take JRuby/Sinatra for example: But I am not 100% sure what that means
if the "show-case" should/would also demonstrate our java libs (e.g.
AG-Security).
I *think* with TorqueBox/JRuby we can use most of our "java libs", but
does require JRuby (and TB), right? So I am not 100% sure on that....
Greetings,
Matthias

Functionality would be additive as we completed it, so the idea would need to be easily
"upgraded" as we go.

It would require documentation to discuss complexities and usage for an advanced
application, but would not need to cover the bread and butter imo (that is what the
quickstart tutorials are for). We would have to commit to long term maintenance of this
as well.

I agree

I'd that's what they wanted to use but they shouldn't have to be familiar with
that setup to understand where the

I agree that our central backend should have those requirements and by default the clients
would point there but it should be clear that the clients aren't tied to one backend
as well.

directory right next to the /clients directory :-)

With the various servers, configuration, certs, etc... At the same time, we need a demo
(both sooner, and simpler) than the showcase demo for the related tutorials, docs, etc...

into digestible pieces.

requirements for quick starts that we should consider as well, where they don't
conflict. For example build tools, deployment options, etc...

this is a server side quickstart (demoing a new feature in security for example), it would
be a single quickstart with 3 (or 4 with hybrid) very simple clients included. For client
quickstarts, an idea I had would be that they could be there own quickstart so there would
be 3 or 4 of them and to solve the single backend, we have one more repo for the backend
and it can be included as a git submodule to each quickstart. I'll wait for qmx to
object here :) as I am also not a huge fan of submodules but I think they could solve a
problem here and with appropriate instructions in the README could be handled properly.

I think it is VERY important that all of our client types share a similar approach
(cookbook or not). We don't want completely different approaches by client type. If
we do group quickstarts (some or all) by client how will we handle common server-side
functionality such as that security example above.

We'll need to discuss this as we discuss quickstart planning in general.

Imo, if we aren't committing to maintain it we should not have it our repository.

JBDS efforts. At the very least, imo, some of our quickstarts should be based on
scaffolding, and tooling. Imo many of the example (where possible) should be compatible

>>>>

apply to iOS, and we would need to balance the effort required on a case-by-case basis for
others. It just might not make sense or have a different target than forge or JBDS. That
is fine, I don't want to use this as a handicap, but we should be considering both of
these as we go.
>>>
>>> I agree that we need some forge and tooling specific examples, quickstarts,
what ever. My only concern is that unless we can get the code generated by forge prettier
(proper white space being one of my biggest pet peeves) so that someone looking at the
generated code doesn't struggle to read it, I don't want the demo code scaffolded.
Not sure how possible this is but IMO is very important for the usability of our demos as
learning tools.
>>
>> This is another standard is needed imo, or at least updated and used. Coding
standards for the various languages, IDE config files where possible. There is one in the
repos now, but it has not been updated, review, or maybe even used in a long time.
