Re: Trial for RDi SOA

Amen to Jim,

Joe, you can't "invite" us to waste hundreds of hours for nothing, maybe IBM
can, maybe you can help to IBM, really try to compete with two IBM EGL gurus
are too for indigent sole developers:
at least you can write about how long it took to create the application.

anyway this is not the journey, its logical that IBM try to develop a nice
demo program at any cost, good, but please don't try to include us in the
hard job.
I would prefer all this time and effort in doing real business apps and
making it easy to install and using RDi and EGL (and affordable, too).

And yes, sure, using RPG don't limit you to using javascript and so on,
today js is imprescindible to develop client GUI apps. please when I spoke
about using RPG don't take the argument that without js RPG can't do this or
that.

Guillermo.

Here's the deal: what can you use that will work better? How long

would

it take you to re-create this application, in ANY technology? Here are
the requirements:

Frankly I don't know since I n eed to do the application to find out how
long it takes :) The curse of our business.

I have not played around with the demo application so I have no idea of
the actual functionality, but am only responing based on your outline.

And I'll try to respond generally, but I really am asking people to give
me real estimates for how long it would take, since that's the real
issue: how productive can you be?

Unauthenticated services:
1. View sessions and tracks, with times
2. View descriptions, votes and tags
3. View comments in realtime
4. Find current sessions
5. Search sessions on keywords

Unauthenticated means no sessions. Ok. Not bad. Real time means SQL.

Not SQL. Calls to RPG.

Authenticated services
1. Register/login (we use email authentication)
2. Maintain schedule
3. Social networking: votes, tags, comments
4. Recommend sessions
5. Online chat

Chat means Ajax. Jetty has a demo application, I'll just nick... eh...
adapt.

A bit more than that. Chat sessions are specific to sessions. You
click on a session's chat button and you're placed there. Comments are
stored in the database, so that people can view past comments as well as
watch (and participate in) ongoing conversations.

Administrative services
1. Maintain sessions and tracks
2. Enable/disable users
3. Clear/maintain tags, votes and comments

Hmm... Would a "Keep stuff in a spreadsheet and upload new versions with
changes" do?

Nope. Users are added by people registering - wouldn't show up in
spreadsheet. Either would any of the social networking stuff. That's
why spreadsheets (to put it politely) suck for real applications.

All data is to be stored on the System i. Responses for the most part
should be subsecond.

Naturally. I have just played around with pooled java toolbox
connections where the overhead for doing a program call is 1-2 ms, so it
CAN be done :)

Would such a challenge include data files so we just talk creating
functionality or would everything have to be made from scratch?

Well, we created everything from scratch. Why shouldn't you? <grin>

The RSDC scheduler is a benchmark. I'd love to see it reproduced using
any technology, so that we can compare approaches.

I have no idea what you are talking about :)

I'm tired of listening to everyone say how good (TECHNOLOGY X) is. Time
to prove it. It's easy to sit on a mailing list and pontificate. It's
a lot harder to really do something.

But we've done it, so now it's time for others to match it.

I think we need to be fair here. Chris Laffra isn't just some guy off
the street that is trying to program business apps like the rest of us.
He is the Chief Architect of EGL Rich UI. Come on, that's like you
challenging me and my co-worker to fight you and the heavyweight champ.
Not exactly a fair fight. I think that if we got the head architect on
the .NET side or the head architect of FLEX to help front-end an i-based
app, we could do pretty well to compete with your app.

I think the important thing here is that all of this IS possible with
IBM tools. Anything claiming to be the 'best' is just someone's opinion
based on their experience. Everyone else's mileage may vary.
